Mickey needs $80 to buy a fish tank for Nemo. So far he has been able to save $8. He is going to be cleaning up this weekend at the park where he makes $9 per hour. Which inequality shows the minimum number of hours h , that Mickey can work at the park to earn enough to buy the fish tank for Nemo?

a. 8 + 9n ≤ 80, so n ≤ 8

b. 8 + 9n ≥ 80, so n ≥ 8

c. 9n ≥ 80 + 8, so n ≥ 9.8

d. 9n ≤ 80 + 8, so n ≤ 9.8

Answer:

there are no figures showing up

Step-by-step explanation:

Answer:

[tex]x= 7, y=4\sqrt{2}[/tex]

Correct option B.

Step-by-step explanation:

The diagram shows a trapezoid with a base angle of 45° and the other base angle of 90°.

We have completed the diagram to draw a perpendicular line over the base of height h=4. A triangle is formed with an angle of 45°.

Recall a right triangle with angles of 45° is isosceles, thus the base and the height are h=4. Please check the diagram below.

For that triangle, we apply Pythagora's Theorem:

[tex]y^2=4^2+4^2=2*4^2[/tex]

Thus:

[tex]y=\sqrt{2*4^4}=4\sqrt{2}[/tex]

[tex]y=4\sqrt{2}[/tex]

The base of the trapezoid x is h + 3 = 7

Thus:

[tex]\mathbf{x= 7, y=4\sqrt{2}}[/tex]

Correct option B.

To figure out what a fraction is as a decimal u would do the top divided by the bottom

For this fraction it would look like this,

8 divided by 9 which would get you 0.88888888888

So your decimal is  0.889

Its not 0.888 because with decimals since a typical decimal is show as 2-3 numbers it would be rounded up to keep it as 3 numbers or less. so this would be 0.889 or if that doesnt work 0.888 with a line over the last 8.

Answer:

0.889

Step-by-step explanation:

0.88888888 repeating the 3rd 8 is the thousandth place so you look at your neighbor and it is 5 or higher so you round up to 0.889

Answer:

x = 2 , y = 1

Step-by-step explanation:

Solve the following system:

{y = 3 x - 5 | (equation 1)

3 y + 6 x = 15 | (equation 2)

Express the system in standard form:

{-(3 x) + y = -5 | (equation 1)

6 x + 3 y = 15 | (equation 2)

Swap equation 1 with equation 2:

{6 x + 3 y = 15 | (equation 1)

-(3 x) + y = -5 | (equation 2)

Add 1/2 × (equation 1) to equation 2:

{6 x + 3 y = 15 | (equation 1)

0 x+(5 y)/2 = 5/2 | (equation 2)

Divide equation 1 by 3:

{2 x + y = 5 | (equation 1)

0 x+(5 y)/2 = 5/2 | (equation 2)

Multiply equation 2 by 2/5:

{2 x + y = 5 | (equation 1)

0 x+y = 1 | (equation 2)

Subtract equation 2 from equation 1:

{2 x+0 y = 4 | (equation 1)

0 x+y = 1 | (equation 2)

Divide equation 1 by 2:

{x+0 y = 2 | (equation 1)

0 x+y = 1 | (equation 2)

Collect results:

Answer: {x = 2 , y = 1

Answer:

Ava made 4 three point shots and 8 two point shots.

Step-by-step explanation:

Let X represent the number of 3-point shots and Y represent the number of 2-point shots.

Then using the provided data two equations can be formed:

X + Y = 12...(i)

3X + 2Y = 28...(ii)

Solve (i) and (ii) simultaneously:

Multiply (i) by 2 and subtract (ii) from (i) as follows:

2X + 2Y = 24

-3X - 2Y = -28

-X = -4

X = 4

Substitute X = 4 in (i) and solve for Y as follows:

X + Y = 12

4 + Y = 12

Y = 8

Thus, Ava made 4 3-point shots and 8 2-point shots.

I would go with A. it's the only one that makes sense

Answer: 52.5

Step-by-step explanation: 2(3x+10)+2(x+10)=360 because all the sides of a rhombus equal 360 and alternate sides are equal

8x+20=360

-20=-20

8x/8=340/8

x=42.5

x+10. 42.5+10=52.5

D=52.5

The measure of ∠D in parallelogram ABCD is 52.5°.

A parallelogram is a 2D figure in which opposite sides are equal.

We know in a parallelogram sum of the adjacent angles is 180° and opposite angles are equal.

∴ In a parallelogram, ABCD ∠A = ∠C and ∠B = ∠D and we also know that sum of all the interior angles of a parallelogram is 360°.

∴ ∠A + ∠B + ∠C + ∠D = 360°.

2∠A + 2∠B = 360°.

2(3x) + 2(x+10) = 360°.

6x + 2x + 20° = 360°.

8x = 340°.

x = 42.5°.

Given, ∠B = ∠D = x + 10° = 42.5° + 10° = 52.5°.
