Answer:

50

Step-by-step explanation:

35/7= 5

5*10=50

Answer:

50 people in the choir

Step-by-step explanation:

we can solve for x, assuming x is the value in which 1 is on the ratio. 7x=35, so the value of x would be 5. Next, we must multiply x by 3 since that is what the ratio states. If we do this, we will get 5*3, or 15. Therefore, there are 15 boys in the choir. Last, we have to add 15+35 to get the total number of people in the choir. There are 50 people in the choir.

Hope this helps! :)

Answer:

2 cans

Step-by-step explanation:

Given that :

Radius of pool = 30 feets

Using the relation for the Area of a circle :

Area = pi*r^2

Thus,

Area of pool = 3.14 * 30^2

Area of pool = 3.14 * 900 = 2826feet²

Paints are sold in cans of 5 gallon

5 gallon of paint = 1500 feet²

Least number of 5 gallon can required :

2826 feet² / 1500 feet² = 1.884 cans

Hence,

Least number of 5 gallon can required = 2 cans

Answer:

Approximately $14.20

Step-by-step explanation:

Let the cost of the groceries be represented by c, then;

cost price + VAT = c + (5% of c)

To get the value of the cost, c, that would make him spend as close to $15. Since the tax is 5% of the cost price, then the cost price would be close to $15.

Let c = $14.20, then;

So that,

c + (5% of c) = 14.20 + (5% of 14.20)

                    = 14.20 + 0.71

                    = $14.91

Thus, the greatest total cost of groceries Darla can spend in order to spend as close to $15 as possible is approximately $14.20.

Range: {-4, 3, 5}

Step-by-step explanation:

The range of a function includes all the set of possible output, or y-values in a given data set of a function.

Thus, the range of the function, {(2, 3), (-3, 5), (6, -4)} includes 3, 5, and -4.

This can be written as:

Range: {-4, 3, 5}

Answer:

Positive 4

Step-by-step explanation:

Factors for 8 => 1, 2, 4, 8

factors for 12 => 1, 2, 3, 4, 6, 12

the common greater number is 4. So the plot will be on posotive 4. Above sea level, which is above zero.

Answer:

y = [tex]\frac{-1}{4}[/tex]x - 3

Step-by-step explanation:

(4, -4) (-8, -1)

y = mx + b

equation for slop: [tex]\frac{y1 - y2}{x1 - x2}[/tex]

[tex]\frac{-4 + 1}{4 + 8}[/tex] = [tex]\frac{-3}{12}[/tex] = [tex]\frac{-1}{4}[/tex]

y = [tex]\frac{-1}{4}[/tex]x - 3

Answer:

60 hours

Step-by-step explanation:

We are given;

Initial amount: A_o = 64 mg

Half life; T_½ = 15 hours

Amount left: A = 4 mg

To get the time that 4 mg of Sodium-24 remain, we will use the formula;

A = A_o(½^(t/T_½))

Where t is the time that 4 mg of Sodium-24 remain.

Thus;

4 = 64 × ½^(t/15)

Divide both sides by 64 to get;

4/64 = 2^(t/15)

0.0625 = ½^(t/15)

In 0.0625 = (t/15) In 0.5

-2.7726 = (t/15) × -0.6931

t = (-2.7726 × 15)/-0.6931

t = 60 hours

Answer:

5

Step-by-step explanation:

5 courses worth 4 credits have Diego completed. Therefore, option B is the correct answer.

We need to find how many courses worth 4 credits has Diego completed.

In mathematics, a system of equations, also known as a set of simultaneous or an equation system, is a finite set of equations for which we sought common solutions. A system of equations can be classified in a similar manner as single equations.

Now, let the courses worth 3 credits be x and the courses worth 4 credits be y.

Now, in total Diego completed 18 courses

That is, x+y=18 ------(I)

Diego has earned a total of 59 credits

So, 3x+4y=59 ------(II)

Multiply the equation (I) by 3, that is 3x+3y=54 ------(III)

Now, subtract the equation (III) from (II) and simplify.

That is, 3x+4y-(3x+3y)=59-54

⇒y=5

Substitute y=5 in the equation (I) and simplify

That is, x=13

Therefore, 5 courses worth 4 credits have Diego completed.

Estimated Answer: 30

Work: Since 2.31 is below 2.50, I rounded is back down to 2. Since 2.58 is above 2.50, I rounded it up to 3, and Since 5 isn't a decimal, it stays at 5. So, the new "Estimated" multiplication problem is 2 x 3 x 5 = 30

Answer:

16 ft²

Step-by-step explanation:

The complete question is attached.

A trapezoid is a quadrilateral (has four sides) with one a parallel base. The base angles and the diagonals of an isosceles trapezoid are equal.

The area of a trapezoid = [(sum of the parallel bases) / 2] * height of the trapezoid.

Given that the parallel bases are 3 ft and 5 ft, while the height of the trapezoid is 4 ft. Hence:

The area of a trapezoid = [(3 + 5)/2] * 4

The area of a trapezoid = 16 ft²

Explanation:

Compare two graphs, the transformation of the graph is g(x) while f(x) is an original.

[tex]f(x) = 6x \\ g(x) = 6x -5[/tex]

For a linear function or line graph.

[tex]y = mx + b[/tex]

This means that the function y has the graph that shifts up b units.

[tex]y = mx - b[/tex]

While on the other hands, if the function y has -b as y-intercept. We can say that the function has the graph that shifts down b units.

Rather say that. If the constant term is positive, it shifts up and if the constant term is negative, it shifts down.

Back to the answer.

Comparing two graphs, from f(x) and g(x) —

We can say that function g shifts down 5 units from f(x) ^ Read the topic above before this ^

Thus, the answer is B.

Answer:

Brass + Brass = Woodwind

Brass + Woodwind = 150

Brass = 50, Woodwind = 100

Step-by-step explanation:

Hi there!

The two addition equations would be:

Brass + Brass = Woodwind

(As there are twice as many woodwind as brass)

AND

Brass + Woodwind = 150

(As there are 150 of those instruments in total)

These two equations fully describe this situation, and you can use them to solve the problem using substitution as well.

Since Woodwind = Brass + Brass, then:

Brass + Woodwind =150

Can also be written as:

Brass + (Brass+Brass) = 150

Now we can solve by combining all the like terms which gives us:

3*Brass = 150

Brass = 150/3

Brass = 50 meaning that Woodwind = 100, as 50+50=100.

x = 76

Step-by-step explanation:

Given

f(x) = [tex]\frac{1}{4}[/tex] x + 5 and f(x) = 24, then equate the right sides

[tex]\frac{1}{4}[/tex] x + 5 = 24 ( subtract 5 from both sides )

[tex]\frac{1}{4}[/tex] x = 19 ( multiply both sides by 4 to clear the fraction )

x = 76
