Answer:

Mike will only need 42 quarters to make 10.50

Step-by-step explanation:

=========================================================

Explanation:

The quotient is the result after a division problem.

As another example, we would say that 9 is the quotient of 27 and 3 because 27 ÷ 3 = 9

We can use the slash symbol / to mean division. So we could say 27/3 = 9

Going back to the answer, we could rewrite j ÷ 9 as j/9

The order is important. This means j ÷ 9 is different from 9 ÷ j which represents "the quotient of 9 and j".

Answer:

35 or -35

Step-by-step explanation:

i have no idea what u mean by value, so it's either 35, because of absolute value, or -35.

Ask properly! Question is not clear!

Answer: Por ejemplo, un televisor podría costarle originalmente $ 5000. Determine el porcentaje de descuento: en nuestra tienda de ejemplo, todo tiene un 75% de descuento. La suma que queda en su bolsillo, sus ahorros, es simplemente estos dos valores multiplicados entre sí: 75% * $ 5000 = 0,75 * $ 5000 = $ 3750.

Answer:

15.08 m

Step-by-step explanation:

The angle XZW :

XZW + 108° = 180°

XZW = 180° - 108°

XZW = 72°

Length of an arc = θ / 360 * πd

d = diameter = XV = 24

Length of arc XW = (72/360) * π * 24

Length of arc XW = 15.0796

Length of XW = 15.08 m

Answer:

15.08

the answer is D have a good day

Answer:

(a) Output = 37

(b) Input = 9

Step-by-step explanation:

Given

[tex]y =x5 - 3[/tex]

Solving (a): Output, when input = 8

This means that, we solve for y when x = 8

So, we have:

[tex]y =x5 - 3[/tex]

[tex]y =8*5 - 3[/tex]

[tex]y =40 - 3[/tex]

[tex]y = 37[/tex]

Solving (b): Input, when output = 42

This means that, we solve for x when y = 42

So, we have:

[tex]y =x5 - 3[/tex]

[tex]42 = x5 - 3[/tex]

Collect like terms

[tex]x5 = 42 + 3[/tex]

[tex]x5 = 45[/tex]

Divide both sides by 5

[tex]x = 9[/tex]

Answer:

8

Answer:

1st One: 12

2nd One: 27.3

Step-by-step explanation:

Both shapes- from what I can see- are right triangles. This means each shape is 90 degrees. If you subtract the given number by 90, you'll have your missing value :)

Answer:

2-Angle V= 90-78=12°

4-Angle Y= 90-62.7=27.3°

Answer:ik i am late but it is 4.4 for the people that need it now

Step-by-step explanation:

Answer:

18 cm

Step-by-step explanation:

Since the pyramids are similar then the ratio of corresponding sides are equal, that is

12 ÷ 4 = 3

Then the height of the larger pyramid is 3 times the height of the smaller.

height of larger pyramid = 3 × 6 = 18 cm

Answer:

3/5

Step-by-step explanation:

there are 5 cards and chances of picking 4 or 7 which are three cards (since there are two 7s) gives u a probability of 3/5 or 60% chance.

Answer:

3/10

Step-by-step explanation:

y2 - y1 / x2 - x1

4 - 1 / 4 - (-6)

3/ 10

Answer:

Step-by-step explanation:

y1-y2

--------

x1-x2

so

and (x1,y1) and (x2,y2) are those points so plug it in

(1-4)/(-6-4) so that simplifies to -3/-10 so just 3/10 is the slope.

Hope this helps!

Answer:

17.50

Step-by-step explanation:

you really don't need to know the tax amount.

20% of x = 3.50

(20/100) x = 3.50  Divide top and bottom of the left number by 20

(20÷20) / (100÷20)  *  x = 3.50

(1/5) x = 3.50           Multiply both sides by 5  

x = 3.50 * 5

x = 17.50

The meal cost 17.50

Answer:

B)

Step-by-step explanation:

to get the converse, interchange the hypothesis and conclusion

in this case the hypothesis is "if it is snowing" and the conclusion is "then it is my birthday"

Converse would then be "If it is my birthday, then it is snowing"

Answer:

It is Quantitative.

Step-by-step explanation:

Quantitative data is information about quantities; information that can be measured with numbers.

Qualitative data describes qualities or characteristics; information collected using questionnaires, interviews, or observation, and frequently appears in narrative form.

Examples:

It is 25° Celcius today. - Quantitative

I drooled after smelling freshly baked cookies. - Qualitative

Tips:

Think of Quantitative as Quantity; numbers.

Think of Qualitative as Quality; description/characteristics.

Answer: C

Step-by-step explanation:

The two lines meet at (3,2). always read these things by doing the horazontal line and then the vertical one.

Answer:

Area = B x H + L (sum of sides of triangle)

        = 9 x 12 + 10 (12 + 15 + 9)

        = 108 + 360

        =[tex]468in^2[/tex]

Either your options are wrong or question is to find lateral surface.

Lateral Surface area = ( a + b + c) x H , where a, b , c are sides of the triangle.

Lateral Surface Area = (12 + 15 + 9) x 10

                                =[tex]360in^2[/tex]

Answer:

c. 29.3 cubic mi

Step-by-step explanation:

Applying,

V = πr²h/3.............. Equation 1

Where V = volume of the cone, r = radius of the circular base, h = height of the cone, π = pie

From the diagram,

Given: h = 7 mi, r = 2 mi

Constant: π = 3.14

Substitute these values into equation 1

V = 3.14(7×2²)/3

V = 29.3 cubic mi

Hence the right answer is c. 29.3 cubic mi

Answer: 12

Step-by-step explanation: The mean is basically the average. So, start by lining up the numbers from smallest to largest. 1, 3, 4, 8, 14, 18, 19, 19, 22. Then, add them all together. You get 108. Then, divide 108 by the number or numbers in the data set, which in this case is 9. So 108 divided by 9 = 12. Your answer is A. --> 12

Answer:

Perimeter of PQR = 37 units (Approx.)

Step-by-step explanation:

Using graph;

Coordinate of P = (-2 , -4)

Coordinate of Q = (16 , -4)

Coordinate of R = (7 , -7)

Find:

Perimeter of PQR

Computation:

Distance between two point = √(x1 - x2)² + (y1 - y2)²

Distance between PQ = √(-2 - 16)² + (-4 - 4)²

Distance between PQ = 18 unit

Distance between QR = √(16 - 7)² + (-4 + 7)²

Distance between QR = √81 + 9

Distance between QR = 9.48 unit (Approx.)

Distance between RP = √(7 + 2)² + (-7 + 4)²

Distance between RP = √81 + 9

Distance between RP = 9.48 unit (Approx.)

Perimeter of PQR = PQ + QR + RP

Perimeter of PQR = 18 + 9.48 + 9.48

Perimeter of PQR = 36.96

Perimeter of PQR = 37 units (Approx.)

Answer:

4 hours

Step-by-step explanation:

If it took them together with a total of 6 hours and Oliver is half as fast meaning Jose is faster it will take Jose 4 hours.

A simple equation is

6= 4+2

And the 2 would be Oliver since Oliver is half as fast.
