Step-by-step explanation:

x+y=7

x=7-y

So x=7-y

Put this in 5(7-y)+45y=195

35-5y+45y=195

35+40y=195

40y=195-35

40y=160

y=160/40

y=4

A tropical punch recipe calls for 300 ml of sugar for every 222 flavor packages. Write an equation that shows the relationship between s, the amount of sugar in milliliters, and f, the number of flavor packages for this recipe.

Answers

Answer:

s = 150f

Step-by-step explanation:

A tropical punch recipe calls for 300 ml of sugar for every 2 flavor packages. Write an equation that shows the relationship between s, the amount of sugar in milliliters, and f, the number of flavor packages for this recipe.

The amount of sugar in milliliters = s

The amount of flavor packages for these recipe = f

The relationship between 2 variables

= y ∝ x

y = kx

k = constant of proportionality

Hence:

s ∝ f

s = kf

Note ,

s = 300

f = 2

300 = 2k

k = 300/2

k = 150

Therefore, the equation that shows the relationship between s, the amount of sugar in milliliters, and f, the number of flavor packages for this recipe is:

s = kf

s = 150f

Answer:

2=150f

IM HONESTLY DESPERATE THIRD TIME DOING THIS WILL BRAINLEIST- what are some similarities and differences of incenter and circumcenter of triangles?

Answers

Answer:

Incenter is the point for a triangle where the center of the circle that will be drawn to be tangent to all three sides of the triangle, the circle will be inside (inscribed within ) the triangle. The incenter is the point where all three angle bisectors of the triangle intersect. The incenter is the point that is equidistant from all three sides of the triangle. The perpendicular distance to each side will be a radius of the incenter circle

Circumcenter is the point for a triangle where the center of the circle that will be drawn that is tangent to all three vertices of the triangle. The circle will be outside (circumscribed about) the triangle. The circumcenter is the point where all three perpendicular bisectors of the sides of the triangle intersect. The circumcenter is equidistant to all three vertices of the triangle.The radii of the circle will touch each of the three vertices of the circle .

Answers

Answer:

By 2034 Texas per capita income would reach at least $50,000

Step-by-step explanation:

Given;

[tex]I(t) = 27,992(1.017)^t[/tex]

Converting the given function to log;

[tex]I(t) = 27,992(1.017)^t \\\\\frac{I(t)}{27,992} = (1.017)^t\\\\Log_{1.017} ( \frac{I(t)}{27,992} )= t \\\\(Based \ on \ log \ rule; if \ a = b^y , in \ log \ it \ will \ be \ written \ as, Log_b \ a = y)[/tex]

(B) When I(t) = $50,000, the time "t" will become;

[tex]Log_{1.017} ( \frac{I(t)}{27,992} )= t\\\\Log_{1.017} ( \frac{50,000}{27,992} ) = t\\\\Log_{1.017} (1.7862) = t\\\\34.4 \ years = t[/tex]

Thus, by 2034 Texas per capita income would reach at least $50,000

Answers

Answer:

45

Step-by-step explanation:

Answer:

a = 45

b = 15

Step-by-step explanation:

From the information given, you can deduce that both ΔPQR and ΔPSR are isosceles triangles that share base PR. This means that ∠a = ∠SRP because the base angles of an isosceles triangle are always congruent.

Because the vertex of ΔPSR is 90°, you know that the base angles add up to 90 because 180(sum of a triangle's angles) - 90 = 90. 90/2 = 45, so a = 45.

To find b, you need to subtract the base angle of ΔPSR from the base angle of ΔPQR. ΔPQR's base angle is 60, because 180 - 60 = 120 and 120/2 = 60. 60 - 45 = 15, so b = 15.

The delivery charge and daily rate to lease a construction crane are listed below for two companies.
High Top Cranes charges $744 for delivery and $3,290 per day.
Big Lift Equipment charges $1,428 for delivery and $3,214 per day.
If Builder's Construction Company leases a crane for 11 days, which leasing company has a lower total cost?

Answers

Answer: Big Lift Equipment

Step-by-step explanation:

From the question,

High Top Cranes charges $744 for delivery and $3,290 per day. Since Builder's Construction Company leases a crane for 11 days, the cost will be:

= $744 + $3290(11)

= $744 + $36190

= $36934

Big Lift Equipment charges $1,428 for delivery and $3,214 per day. Since Builder's Construction Company leases a crane for 11 days, the cost will be:

= $1428 + $3214(11)

= $1428 + $35354

= $36782

Based on the calculations, Big Lift Equipment has a lower cost

Which equations and/or functions represent the graphed line? Select three options.


f(x)=1/5x-4
f(x)=1/2x+2
f(x)=1/2+1
y-3=1/2(x-2)
y-1=1/2(x+2)

Answers

Answer:

The second one, the fourth one, and the fifth one.

f(x)=(1/2)x+2

y-3=1/2(x-2)

y-1=1/2(x+2)

The three equations that represent the graphed line are:

f(x) = (1/2)x + 2

y - 1 = (1/2)(x + 2)

y - 3 = (1/2)(x - 2)

To identify which equations and/or functions represent the graphed line, we can compare the given equations with the characteristics of the graph.

The graphed line appears to have a slope of 1/2 and passes through the point (0, 1). Let's check the options:

f(x) = (1/5)x - 4: This equation has a slope of 1/5, not 1/2, so it does not represent the graphed line.

f(x) = (1/2)x + 2: This equation has the correct slope of 1/2, but it does not pass through the point (0, 1), so it does not represent the graphed line.

f(x) = (1/2) + 1: This equation is not in slope-intercept form and does not represent the graphed line.

y - 3 = (1/2)(x - 2): This equation has the correct slope of 1/2 and passes through the point (2, 3). However, it does not pass through the point (0, 1), so it does not represent the graphed line.

y - 1 = (1/2)(x + 2): This equation has the correct slope of 1/2 and passes through the point (−2, 1) (after rearranging to slope-intercept form). It also passes through the point (0, 1), which matches the graph.

The three equations that represent the graphed line are:

f(x) = (1/2)x + 2

y - 1 = (1/2)(x + 2)

y - 3 = (1/2)(x - 2)

Logan is working two summer jobs, making $18 per hour tutoring and making $10 per hour clearing tables. In a given week, he can work a maximum of 13 total hours and must earn at least $170. If xx represents the number of hours tutoring and yy represents the number of hours clearing tables, write and solve a system of inequalities graphically and determine one possible solution.

Answers

Answer: he could work 7 hours tutoring and 6 hours clearing tables

Step-by-step explanation:

The system of inequalities can be used to find the number of hours Logan

can spend on each job in a week.

Response:

The system of inequalities are;

x + y ≤ 1318·x + 10·y ≥ 170

A possible solution of the system of inequality obtained from the graph is the point (5, 8)

x = 5, and y = 8Methods used to solve the inequality graphically

The amount Logan makes per hour tutoring = $18 per hour

The amount he makes clearing tables = $10 per hour

Number of hours Logan can work in a week = 13

Amount he must earn in a week = At least $170

Number of hours he spends tutoring = x

Number of hours he spends clearing tables = y

Based on the given information, we have;

x + y ≤ 1318·x + 10·y ≥ 170

Please find attached the graph of the above inequality showing the feasible region.

A possible solution obtained from the feasible region is the point of intersection of the two inequalities which is the point (5, 8), which gives;

A possible solution is x = 5, y = 8

Therefore, Logan can spend 5 hours tutoring and 8 hours clearing tables in a week to work for 13 hours and make $170.

A Formidable HunterI remember well the great horned owl that sat on the windowsill of my kindergarten classroom. It was stuffed, of course, but quite imposing nonetheless. This grand specimen was nearly two feet long with brown, white and rusty red feathers. Its yellow eyes were large and perfectly round, giving it a wise look. Its talons were thick and sharp, and on its brow two curved feathers stuck up, looking just like two horns. I got the impression that this bird was a great hunter.Of the 145 species of owl, the great horned is the largest. Owls live in most parts of the world, ranging from tropical to subarctic climates. The elf owl is the smallest at only six inches, but no matter what their size, all owls are good hunters. They hunt under cover of night, so their prey can't see them. Unlike other birds, owls have large, soft feathers that allow them to fly without making noise, which also makes them good predators. Farmers like owls because they keep pests such as mice, voles, rats and even rabbits from their crops and stores of grain. And they have hearty appetites. Henry Williamson, a farmer in England, had eleven barn owls on his farm. He kept careful watch on their hunting habits and was astounded to find that together they ate 150 mice each night! While farmers may be grateful to owls, owners of cats and small dogs should beware: owls have been known to pluck up small pets that unknowingly wander into the birds' hunting zones.Select the correct answer.Why might it be difficult to keep an owl as a pet?A.
