Answer: 4

Step-by-step explanation:

Change the 2.5 to an improper fraction, then multiply by the reciprocal of 5/8.

[tex]2\frac{1}{2} /\frac{5}{8} =\frac{5}{2}*\frac{8}{5}=\frac{40}{10} =4[/tex]

Conversion a mixed number 2 1/

to a improper fraction: 2 1/2 = 2 1/

2

= 2 · 2 + 1/

= 4 + 1/

= 5/

To find new numerator:

a) Multiply the whole number 2 by the denominator 2. Whole number 2 equally 2 * 2/

2

= 4/

2

b) Add the answer from previous step 4 to the numerator 1. New numerator is 4 + 1 = 5

c) Write a previous answer (new numerator 5) over the denominator 2.

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 5/

Answer:

1. 9 = x

2. y = 2

Just copy these steps on paper, then submit.

Writing it yourself will help you, trust me :)

1. 2(x + 5) = 3x + 1

2(x + 5) = 3x + 1

Distribute the 2

2x + 10 = 3x + 1

-1                    -1

2x + 9 = 3x

-2x         -2x

9 = x

2. 3y - 4 = 6 - 2y

3y - 4 = 6 - 2y

     +4    +4

3y = 10 - 2y

+2y       +2y

5y = 10

Divide both sides by 5

y = 10/5

y = 2

Step-by-step explanation:

The total area of the garden is  31.75 sq meters

The first step is to calculate the radius if the circle

The diameter of the garden is 20 feet

2π × radius= 20

2π × 3.14= 20

6.28π= 20

π= 20/6.28

π= 3.18

The area of the flower garden can be calculated as follows

= π × radius²

= 3.14 × 3.18²

= 3.14 × 10.1124

= 31.75 sq meters

Hence the total area of the garden is 31.75 sq meters

A solution to a quadratic is the same as the root or x intercept (when talking about real numbers). The graph shows that we have exactly one x intercept, which is where the parabola touches the x axis. So we have one root.

Answer:

Adult ticket is $6

Student ticket is $4, as you said.

Step-by-step explanation:

We'll call adult tickets x and student tix y.

14x + 11y = 128

14x + y = 88

First, solve the second equation for y in terms of x:

y = 88- 14x

Then substitute that for y into the first equation:

14x + 11(88-14x) = 128

14x + 968 - 154x = 128

-140x = -840

x = 6  The adult ticket is $6, like you said.

Now take that and solve for y:

y = 88 - 14(6)

y = 88 - 84

y = 4 The student ticket is $4, as you said.

Answer:

D the slope is undefined and the y intercept is -5

Step-by-step explanation:

quadrant II and III are on the left. the only way for a line to pass through those two quadrants without passing through I and I would have to be a negative x intercept. The slope would have to be undefined which would make a diagonal line. if the slope was 1 or anything higher it would end up hitting the other quadrants.

You can solve this by doing Pythagorean theorem. I think thats what its called... a^2+b^2=c^2. So 24 squared plus 18 squared is 900. The square root of 900 is 30. The legnth of the third side is 30.

The distance from the top of the flagpole to the ground is 30 feet.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side.

Given the distance from the base of a flagpole to a point on the ground = 24 feet

height of flagpole = 18 feet

the distance from the top of the flagpole to the ground is x

by Pythagorean theorem, we can find the distance

h² = b² + p²

h = hypotenuse = x

b = base = 24 feet

h = height = 18 feet

x² = 24² + 18²

x² = 576 + 324

x = √900

x = 30 feet

Hence the value of x is 30 feet.

Answer:

y=7x-6

Step-by-step explanation:

You would first pick two coordinates in this case would be ( 0, -6), (1,1). You would find your slope by using the formula y2-y1/x2-x1. Which would give you a slope of 7/1 which is equal to 7. Then you would use point slope formula which is y-y1=m(x-x1). would would plug in the numbers and it would say

y-(-6)=7(x-0). Then you would simplify the y-(-6) which would be y+6 then you would distribute the 7. Your whole equation would look like y+6=7x+0. Then you would use inverse operations and subtract -6 from the left side of the equals and subtract it from 0 giving you -6. Therefore your whole equation would be y=7x-6. Hoped this helped.

Step-by-step explanation:

The measure of a godown = 40 m × 25 m × 10 m

The measure of wooden crate = 1.5 m × 1.25 m × 0.5 m

We need to find the maximum number of wooden crates that can be stored in the godown. Let there are n wooden crates. So,

[tex]n=\dfrac{40\times 25\times 10}{1.5\times 1.25\times 0.5}\\\\n=10666.67[/tex]

or

n = 10667

Hence, there are approx 10667 wooden crates can be stored.
