Need help with this question I don't understand.

Answer:

2x - 9 = 5x

Step-by-step explanation:

This question is asking you to write an equation for the statement given. Twice of x is 2 times x, or 2x. Diminished by 9 means subtracting 9 from 2x, so 2x-9. Finally this is equal to 5x. So, 2x-9=5x.

Answer:

well we know d>30 and 1.00>d

so i think the answer would be just that d>30=1.00>d

Step-by-step explanation:

Answer:

30=1.00>d

Step-by-step explanation:

Jada has  dimes. She has more than 30 cents but less than a dollar.

Write two inequalities that represent how many dimes Jada has.

Can  be 10?

How many possible solutions make both inequalities true? If possible, describe or list the solutions.  

Order these numbers from greatest to least: -4 ,1/4 , 0, 4, 3  1/2 ,7/4  , 5/4

hope this helps

Answer:

Well for these problems you need to know the formula so

First off we have to square the radius thats just a fancy way of saying multiply by itself so 2.8 x 2.8 = 7.84 Now we just multiply that by pi!

so 3.14 x 7.84 = 24.6176 now sense we have to round it our final answer would be 24.6

Answer:

yes it is :)

Step-by-step explanation:

Step-by-step explanation:

if y varies inversely as x^2 then 1/y=x^2

note: there needs to be a constant

so let's just say that the constant is k

so we multiply k by x^2 to equal 1/y

1/y=(x^2)k

put in the values for x and y

x=4 and y=1/4

1/(1/4)=(4^2)k

4/16=k

1/4=k

now we insert k back into the first equation that we made

1/y=(x^2)(1/4)

put in the value for y

y=1

x=?

1/1=(x^2)(1/4)

4=x^2

±[tex]\sqrt{4}[/tex]=x

2=x and -2=x

Hope that helps :)

Answer:

x = 2

Step-by-step explanation:

y ∝ [tex]\frac{1}{x^{2} }[/tex] ⇒ y = [tex]\frac{k}{x^{2} }[/tex] (where k is the constant of proportionality)

k = x²y

When x = 4 and y = [tex]\frac{1}{4}[/tex],

k = (4)² × [tex]\frac{1}{4}[/tex]

  = [tex]16 * \frac{1}{4}[/tex]

  = 4

So, y = [tex]\frac{4}{x^{2} }[/tex]

When y = 1,

[tex]1 = \frac{4}{x^{2} }[/tex]

x² = 4

√x² = ±√4

∴ x = 2 or -2

Answer:

49.5

Step-by-step explanation:

find the area of the triangle and rectangle then add them together

Rectangle: 5 x 5 = 25

Triangle = 1/2 x 7 x 7 = 24.5

24.5 + 25 = 49.5

hope this helps and is right. p.s. i really need brainliest :)

Answer:

Profit = $2.50

Step-by-step explanation:

Expenses:

(325 x 0.30) + 95.00 = $192.50

Gross sales:

325 x 0.60 = $195.00

Profit = $2.50

Answer:

1/7^7

Step-by-step explanation:

Exponents are simply repeated multiplication.

Here, 1/7 is multiplied by itself 7 times.

Therefore, the exponent is 1/7^7.

Answer:

y=1.5x+2

Step-by-step explanation:

Step 1, find slope

(20-8)/(12-4)

12/8 = 1.5

slope = 1.5

Step 2, find the y-intercept

y = 1.5x+b

use point (4,8)

8 = 1.5(4)+b

8 = 6+b

-6 -6

2 = b

Step 3, put it all in slope-intercept form (y = mx+b)

y = 1.5x+2

Answer: y = 1.5x+2

Step-by-step explanation:

I chose a power strip for this assignment. The dimensions are (2.7in x 13.2in x 1.6cm(0.625in))

Pt A. The surface area of the box is 33.05in (added up all the sides, l2 + w2 + h2 = surface area)

Pt B. 330.5in (33.05 * 10)

Pt C. 22.28in² (= l * w * h --> 2.7in * 13.2in * 0.625in)

Pt D. Scaled down by factor of 1/10: 2.23in²

Good luck!!

Answer:

just look for an cereal box.

Step-by-step explanation:

Answer:

1,800

Step-by-step explanation:

V = l × w × h

V = 15 × 12 × 10

V = 180 × 10

V = 1,800 ft

Step-by-step explanation:

The volume of a box is equal to the length l times the width w times the height h.

[tex]lenght \times width \times height[/tex]

Substitute the values of the length l=10, the width w=15, and the height h=12 into the formula.

[tex]10 \times 15 \times 12[/tex]

Multiply 10 by 15.

[tex]150 \times 12[/tex]

Multiply 150 by 12.

[tex]1800(ft) ^{3} [/tex]

The Volume of the figure is 1800(ft)³.

Answer:

s=150c

$7450

Step-by-step explanation:

Answer:

$7450

Step-by-step explanation:

The equation would be C=5500+150S.

You would then substitute S for 13.

150x13=1950.

1950+5500=7450

The total cost would then be 7450.
