Which percent is equivalent to 720?

[tex]\bf \stackrel{\textit{we know that they are supplementary}}{\stackrel{\measuredangle A}{(3x+18)}~~ + ~~\stackrel{\measuredangle B}{(5x+2)}}~~ = ~~180 \implies 8x+20=180\implies 8x=160 \\\\\\ x=\cfrac{160}{8}\implies \boxed{x = 20} ~\hfill \stackrel{\measuredangle A}{3(20)+18}\implies 78[/tex]

Final answer:

The measure of ∠A, when ∠A and ∠B are supplementary, is found to be 78° after setting up an equation, simplifying it, and solving for x.

Explanation:

If ∠A and ∠B are supplementary angles, the sum of their measures is 180°. We have m∠A=(3x+18)° and m∠B=(5x+2)°. Set up an equation to find the value of x:

3x + 18 + 5x + 2 = 180.

Simplify and solve the equation:

8x + 20 = 180

8x = 160

x = 20

Now, substitute x back into the expression for m∠A:

m∠A = 3(20) + 18

m∠A = 60 + 18

m∠A = 78°

So, the measure of ∠A is 78°.

Answer:

[tex]y = - {10}^{x - 3} - 5[/tex]

Step-by-step explanation:

The parent exponential function given to us is

[tex]y = f(x)= {10}^{x} [/tex]

If this function is reflected over the x-axis, shifted right 3 units and down 5 units, then it becomes:

[tex]y = g(x) = - f(x - 3) - 5[/tex]

This implies that:

[tex]y = g(x) = - {10}^{x - 3} - 5[/tex]

where the negative multplier indicates reflection over x-axis, x-3, indicates shift to the right 3 units, and -5 indicates downward shift 5 units

The IQR for Week 1 is 31, and the IQR for Week 2 is 25.

Step-by-step explanation:

Answer:

D.

The IQR for Week 1 is 31, and the IQR for Week 2 is 25.

The sequence is geometric because it decreases by a factor of 1/27.

In an arithmetic sequence, the terms change by a constant difference, while in a geometric sequence, the terms change by a constant ratio. In this case, the terms of the sequence are decreasing, and the ratio between consecutive terms is 1/27, which is a constant factor.

For example, if the sequence were arithmetic, you would see a consistent subtraction of a fixed number from one term to the next.

Therefore, the sequence is geometric because it follows the pattern of a geometric progression.

The area of the rhombus is [tex]72 \ cm^2[/tex]

Explanation:

It is given that in a rhombus VWXY, the length of the diagonals are [tex]\mathrm{WY}=18 \ {cm}[/tex] and [tex]X V=8 \ {cm}[/tex]

The area of the rhombus can be determined by multiplying the diagonals and dividing by 2.

The area of the rhombus can be determined using the formula,

[tex]A=\frac{p q}{2}[/tex]

where p and q are diagonals of the rhombus.

Substituting the values in the formula, we have,

[tex]A=\frac{18\times 8}{2}[/tex]

Multiplying the numerator, we get,

[tex]A=\frac{144}{2}[/tex]

Dividing by 2, we have,

[tex]A=72 \ cm^2[/tex]

Thus, the area of the rhombus is [tex]72 \ cm^2[/tex]

Answer:

They won £30 in total

Step-by-step explanation:

∵ Sara and Gordon win some money

∵ They share it in the ratio 2 : 1

∵ Sara gets £20

- To solve the problem lets use the ratio method

→  Sara  :  Gordon

→  2        :  1            

→  20      :  x          

By using cross multiplication

∵ 2 × x = 1 × 20

∴ 2 x = 20

- Divide both sides by 2

∴ x = 10

∵ x represents the share of Gordon

∴ Gordon gets £10

- Add their shares to find the total

∴ The total = 20 + 10 = 30

∴ They won £30 in total

Answer:

18

Step-by-step explanation:

4 + 2(7)

This equation can be rewritten like this: 4 + 2 x 7

According to the order of operations, multiplication comes before addition.

So, we can go ahead and multiply 2 and 7 out:

4 + 2 * 7

4 + (2 * 7)

4 + (14)

Then, our second step is to add.

4 + 14 = 18

So, 4 + 2(7) = 18.

18 is your answer.

A. Kellie's minute-per-mile pace 9 minutes per mile.

To find this, divide her time (72 minutes) by the number of miles she went (8). 72 divided by 8 is 9 minutes per mile.

B. Ashley ran 4 miles in 34 minutes. First, divide Ashley's time (102 minutes) by the number of miles she went (12). 102 divided by 12 is 8.5 minutes per mile. Then divide 34 by 8.5 to get how far she went in that time. Thus meaning 4 miles.

C. The difference in time between their 4 miles is 2 minutes. Kellie took 36 minutes to go 4 mile (4 miles times 9 minutes is 36 minutes) and Ashley took 34 minutes to go 4 miles (as stated in part B.) Lastly, subtract 34 from 36 to get the 2 minute difference.

I hope this helps!

Answer:

44L

Step-by-step explanation:

Mary has 20 liters of paint that have white:blue ratio of 2:3. She wants to make a new mix by adding more blue paint until the ratio becomes 1:7. That means the volume of white paint of the old mid and new mix should be the same.

The volume for the second mix will be:

old mix white paint = new mix white paint

2/(3+2) * 20L = 1/(1+7) * V2

2/5 * 20L= 1/8 V2

8L= 1/8 V2

V2= 8L * 8

V2= 64L

If the new mix volume is 64L and old mix volume is 20L, then the blue paint needed to be added will be: 64L- 20L= 44L

Given data:

[tex]$1 \frac{4}{9} \text { and } 2 \frac{1}{3}[/tex]

Plot the points [tex]1 \frac{4}{9} \text { and } 2 \frac{1}{3}[/tex] on the number line.

Let us plot the first point [tex]1\frac{4}{9}[/tex].

1 unit is completed. So count after 1 (indicated) in the number line.

point after 1 is [tex]1\frac{1}{9}[/tex]

point after [tex]1\frac{1}{9}[/tex] is [tex]1\frac{2}{9}[/tex]

point after [tex]1\frac{2}{9}[/tex] is [tex]1\frac{3}{9}[/tex]

point after [tex]1\frac{3}{9}[/tex] is [tex]1\frac{4}{9}[/tex].

So, move 4 points after 1 in the number line is [tex]1\frac{4}{9}[/tex].

Now plot the point [tex]2\frac{1}{3}[/tex].

To make the denominator 9, multiply and divide numerator and denominator by 3.

[tex]$2 \frac{1}{3}=2 \frac{3}{9}[/tex]

2 unit is completed. So count after 2 (indicated) in the number line.

point after 2 is [tex]2\frac{1}{9}[/tex]

point after [tex]2\frac{1}{9}[/tex] is [tex]2\frac{2}{9}[/tex]

point after [tex]2\frac{2}{9}[/tex] is [tex]2\frac{3}{9}=2\frac{1}{3}[/tex]

So, move 3 points after 2 in the number line is [tex]2\frac{1}{9}[/tex].

Step-by-step explanation:

B

Answer:

Step-by-step explanation:

Given that,

y=x+2 equation 1

2x-y=-4 equation 2

This is a simultaneous equation.

Substitute equation 1 into equation 2

2x-y=-4. Since y=x+2

2x-(x+2) = -4

2x-x-2 = -4

x-2 = -4

x = -4+2

x = -2

Also from equation 1

y=x+2

Since x=-2

y=-2+2

y=0

Then, solution (x, y) = (-2,0)

Answer: x = -2, y = 0

Step-by-step explanation:

[tex]y=x+2\\2x-y=-4[/tex]

Substitute y = x+2 in [tex]2x-y=-4[/tex]

Then we get, [tex]2x-(x+2)=-4[/tex]

[tex]2x-x-2=-4\\x-2=-4\\x=-4+2\\x=-2[/tex]

Then substitute x = -2 in any equations, just only one equation. For me, I'd substitute x = -2 in y = x+2

[tex]y=-2+2y=0[/tex]

So the answer is x = -2 and y = 0

Answer:

The height is 3.183 cm.

Step-by-step explanation:

The volume [tex]V[/tex]of a cylinder with base radius [tex]r[/tex] and height [tex]h[/tex] is given by

[tex]V = \pi r^2h[/tex]

Now, if the volume and the radius is given, we can use this equation to work out the height of the cylinder:

[tex]h= \dfrac{V}{\pi r^2 }.[/tex]

For our graduated cylinder,

[tex]V = 490cm^3[/tex]

[tex]r = 7cm[/tex];

therefore,

[tex]h = \dfrac{490cm^3}{\pi (7cm)^2 }[/tex]

[tex]\boxed{h = 3.183\:cm}[/tex]

Thus, the height of the graduated cylinder is 3.183 cm.
