Answers

Answer:

u ≈ 5.7

Step-by-step explanation:

Using the Sine rule in Δ TUV, that is

[tex]\frac{t}{sinT}[/tex] = [tex]\frac{u}{sinU}[/tex] , substitute values

[tex]\frac{2.5}{sin26}[/tex] = [tex]\frac{u}{sin85}[/tex] ( cross- multiply )

u × sin26° = 2.5 × sin85° ( divide both sides by sin26° )

u = [tex]\frac{2.5sin85}{sin26}[/tex] ≈ 5.7 ( to 1 dec. place )

In the formula for average rate of change, what does the triangle in front of the x and y stand for?

d. the percent rate of change of y and x
a
Please select the best answer from the choices provided
A
B

D

Answers

the right answer would be b

The triangle represents delta notation change in y over change in x. the correct option is C.

What is the rate of change?

The pace at which one quantity changes in relation to another quantity is known as the rate of change function. Simply said, the rate of change is calculated by dividing the amount of change in one item by the equal amount of change in another.

The average rate of change is calculated by the formula,

Rate of change = Δy / Δx

Here, the triangle represents the rate of change of the y coordinate with respect to the rate of change of the x coordinate.

What is the value of z?

Answers

Answer: 58 degrees

Step-by-step explanation:

We can see that this triangle is an isosceles triangle so that means the two bottoms angles will be equal

Point S must be equal to point U

z = 58 degrees

Check if this is true:

Angle sum of a triangle: 180 degrees

58 + 58 = 116

180 - 116 = 64

Point T is 64

Since segments JK and RQ are parallel, they are similar by both extending at the same angle and both segments formed by the parallel lines being proportional segments.Since the lengths of segments KZ and ZR are given, they are similar because they are proportional.Since vertical angles are always equivalent by the Vertical Angles Theorem, angles JZK and RZQ are congruent

Because we have 2 sides with a non-included (not in-between the two sides) angle, the triangles are similar by SSA Similarity.

Kamala was ordering tickets from a local theater for two different events. The first event cost $24.95 per ticket plus a $5 processing fee. The second event cost $35.75 per ticket plus a $9.95 processing fee. If Kamala purchased the same number of tickets to each event, what is the simplified expression for the total cost for both events?

Answers

Answer:

T=60.7x+5+14.95

Step-by-step explanation:

let the number of tickets be x

and the number is the same for both tickets

for the first event

the cost is =24.95x+ 5

for the second event

the cost is =35.75x+ 9.95

for both events the total cost is

T=24.95x+ 5+35.75x+ 9.95

T=24.95x+35.75x+5+ 9.95

The simplified expression for the total cost for both events T=60.7x+5+14.95

A fire hydrant is 30 in. tall and casts a shadow 8 in. long. how tall is a

Answers

Using proportions, it is found that a tree that casts a shadow 4 ft long is 180 in. tall.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, a fire hydrant that is 30 in. tall and casts a shadow 8 in. long. We want to find the height of a tree that casts a shadow of 4 ft = 4 x 12 = 48 inches. Hence, the rule of three is given by:

30 in - 8 in

h in - 48 in

Applying cross multiplication:

h = 48 x 30/8

h = 6 x 30.

h = 180 in.

An object is launched at 18.4 meters per second (m/s) from a 36.8-meter tall
platform. The equation for the object's height s at time t seconds after launch is
s(t) = -4.9t2 + 18.4t + 36.8, where s is in meters.

Answers

Answer:

Step-by-step explanation:

Given the equation for the object's height s at time t seconds after launch is

s(t) = -4.9t^2 + 18.4t + 36.8

Since are not asked what to look for, we can as well lok for the time taken for the ball to hot the ground. The ball hits the ground at when s(t) = 0. The equaton becomes:

0 = -4.9t^2 + 18.4t + 36.8

Multiply through by -10

49t^2 - 184t - 368 = 0

factorize the resulting expression

t = 18±√184²-4(49)(-386)/2(49)

t =  18±√338564+75656/78

t =  18±√414220/78

t =  18±643.599/78

t =  661.559/78

t = 8.48secs

Hence the object reaches that ground after 8.48seconds

If 1 foot ≈ 0.305 meter, approximately how many feet are in 8 meters? Round to the nearest tenth, if necessary.

Answers

Answer:

26.22 foot

Step-by-step explanation:

The relation between foot and meter is given by :

1 foot = 0.305 meter

We firstly find value of 1 meter in terms of foot.

So,

[tex]1\ m=\dfrac{1}{0.305 }\ \text{foot}[/tex]

To find no of foot in 8 meters, multiply [tex]\dfrac{1}{0.305 }[/tex] by 8 i.e.

[tex]8\ m=\dfrac{1}{0.305 }\times 8\ m\\\\=26.22\ \text{foot}[/tex]

So, there are 26.22 foot in 8 meters.

A clothing store owner decided to track customers' reasons for returning items. She found that 9% of customers do not provide a reason, 29% say the item did not fit, 13% find a flaw with the item and 4% changed their mind about the purchase. The remaining customers returns gifts purchased for them. What is the probability that out of 40 returns on a given day, 20 are gifts that are being returned?

Answers

Answer:

0.102542

Step-by-step explanation:

Given that 9% of customers do not provide a reason, 29% say the item did not fit, 13% find a flaw with the item, and 4% changed their mind about the purchase.

So, the total percentage of items returned due to no reason, unfit, flaw, and due to changing mind

=9%+29%+13%+4%=55%

As the remaining customers returned gifts purchased for them, so, the percentage of customers who returned gifts =100-55=45%.

So, the fraction of customers who returned gifts=45/100=0.45.

Now, observe that if 1 item returned, there is a chance of 0.45 that the item is a gift.

Moreover, there are only two possibilities for any idem, i.e the idem was a gift or not a gift, so the number of total returned items can be considered a Bernoulli's population.

Let p be the probability of a returned item which is the same for all the returned items,

p=0.45

So, according to Bernoulli's theorem, the probability that out of n=40 returns on a given day, r=20 are gifts is

[tex]\binom{n}{r}p^r(1-p)^{n-r}=\binom{40}{20}(0.45)^{20}(1-0.45)^{40-20}[/tex]

[tex]=0.102542[/tex]

Hence, the probability that 20 returned items are gifts among the total 40 returned items is 0.102542.

B both are proportional

Step-by-step explanation:

so i think by proportional its linear?

so the graph is linear because its a line and its a function, but for the table we first have to find the slope by using the equation

y2 - y1 / x2 - x1

(4, 1.31) and (8, 2.62) will be the points we will use

2.62 - 1.31 / 8 - 4

1.31/4

0.3275x

now i think we use a point we did not use yet sooo (16, 5.24)

we substitute

y = 0.3275x + b

5.24 = 0.3275(16) + b

5.24 = 5.24 + b

b = 0

so the equation would be

y = 0.3275x

now we check with the last point given

6.55 = 0.3275(20) ?

6.55 = 6.55

so i think the answer is both are proportional ?

Answers

Answer:

Patrick's statement is incorrect

Step-by-step explanation:

Crackers come in packages of 24

cheese slices come in packages of 18

He wants one cheese slice for each cracker

Patrick made the statement below "if Andy doesn't want any crackers or cheese slices left over he needs to buy at least 432 of each"

Patrick's statement is incorrect

The lowest common multiple ( L. C. M) of 24 and 18 is 72

Therefore, Andy needs 72 packages of crackers and 72 packages of cheese slice so that no crackers or cheese slice will remain.

Answer:

Answer:

Its A.

Step-by-step explanation:

Add the price up to find the total: 5.50 + 3.75 + 3 = $12.25. Since there were 2 people and they wanted to split the cost- they pay half half. So 12.25 divided by 2 is $6.12.5 but you gotta round it to get an answer hats there so you round it up to 6.13.
