Answer 1

Answer:

im not that good at math but i think is about 101.39388

Step-by-step explanation:

Answer 2

129 units²

The surface area is the area of all the surfaces basically.

so the three rectangular sides are 7 by 5, which gives you 35.

There's three of them, so 105.

There are also two triangular sides that are 6 by 4.

equation to find area of triangle is [tex]\frac{1}{2}[/tex]b · h, which is a fancy equation for half base times height.

so base times height, 24. Half is 12.

There are two sides, so 24 units squared.

105+24 is 129.

Hope this helps, and please consider marking branliest.

SCALE
The two containers are mathematically similar in shape.
The larger container has a volume of 3456 cm3 and a surface area of 1024 cm2.
The smaller container has a volume of 1458 cm3.
Calculate the surface area of the smaller container.

Answers

Answer:

1458/3456 = 27/64 (simplification)

cube root of 27/64 = 3/4

square of 3/4 = 9/16

9/16 multplied by 1024 = 576.

what is the perimeter of the larger rectangle?

Answers

Answer:

30 meters

Step-by-step explanation:

Perimeter smaller rectangle: 2(x+1)+2x = 2x+2+2x

= 4x+2

Perimeter larger rectangle: 2(4x-5)+2(3x-1) = 8x-10+6x-2

= 14x -12

2(4x+2)+2 = 14x-12

8x+4+2 = 14x - 12

8x + 6 = 14x - 12

6 + 12 = 14x - 8x

18 = 6x

x = 3

14*3-12 = 30 meters

Multiply the polynomials: (x + 3)(x2 – 5x + 12)

Answers

Answer:

x³ - 2x² - 3x + 36

Step-by-step explanation:

(x + 3)(x² - 5x + 12)

Each term in the second factor is multiplied by each term in the first factor , that is

x(x² - 5x + 12) + 3(x² - 5x + 12) ← distribute parenthesis

= x³ - 5x² + 12x + 3x² - 15x + 36 ← collect like terms

= x³ - 2x² - 3x + 36

Step-by-step explanation:

x = the area in black

each triangle have area = 80

the area of the 3 triangles without combining them = 80 × 3 = 240

the total area = 210

the total area in the figure = 3 triangles area - 2x

because we have calculated 1 black area not the three of them so we need to add its area once and get rid of the others by subtracting them from the sum of the 3 triangles area

240 - 2x = 210

2x = 30

x = 15

hope that helps

240-2x=210
2x=30

At their last babysitting gig, Zainab made $44 for 8 hours of work and Keziah made $47.25 in 9 hours. Each girl charges a different hourly rate. For a 10 hour job, which girl will make more money? How much more?

Answers

Answers:

Zainab made more moneyShe made $2.50 more

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

Explanation:

To find the hourly rate, we divide the money made over the number of hours.

Zainab's hourly rate = 44/8 = $5.50 per hourKeziah's hourly rate = 47.25/9 = $5.25 per hour

Then we'll multiply each of these results by 10 to figure out how much they made over the 10 hours

Zainab: 5.50*10 = 55 dollarsKeziah: 5.25*10 = 52.50 dollars

We see that Zainab made more money and she made 55-52.5 = 2.50 dollars more.

800 divided by 39 please show steps

Answers

Answer:

20.51282

Step-by-step explanation:

1. Starting by the smallest number that can be divided. 80÷39 equals to 2.

2. Now we write 2 in the answer line.

3. Multiply the result by 39. That makes us 78.

4. Now we write 78 under 800.

5. Subtract the numbers (80-78) and now we have 2.

6. Bring 0 next to our substracted number (2) so that will make it 20.

7. Divide the subtracted number with our initial value (39). That will make us a decimal number (0.512) but we will note the 0 except if you want to make it detailed then note 20.51282

8. Add the 0 next to the 2 that we writed in the start above.

9. Write the remainder (20) next to the quotient.

10. The result is 20 or to be exact 20.51282 and we have a remainder of 20.

how do you convert a repeating decimal in the 10000 place into a fraction?

Answers

Decimal to Fraction

Converting any terminating decimal into a fraction is fairly straightforward. You count the number of decimal places, move the decimal point that number of places to the right, and put the resulting number over "1" followed by that number of zeroes.

For instance:

Convert the decimal 0.7 into a fraction.

This decimal has one decimal place, so I move the decimal point one place to the right, to get 7. Then I put this over "1" followed by one zero (otherwise known as "10") to get: 7/10

Which equation is an identity?
A. (9x/15) + 27 = (9x/15) + (27/15)
B. 3((x/2) + 16) - 16 = (3/2)x
C. -4(3 - 2x) = -12 - 8x
D. -5((x/15) - 16) - 30 = 50 - (1/3)x
E. 36((3/4)x- 2) + 72 =-72 + 27x

Answers

Answer:

Step-by-step explanation:

An equation is an identity if the equation is always true regardless of what value you replace 'x' with.

This means we need to simplify the equations above to see which one will be true for any value of 'x'.

After simplifying equation C, we get -12-8x = -12-8x. Since both sides of the equation are the same, this equation will be true regardless of what value replaces x so this equation is an identity.

Step-by-step explanation:

The sales tax in Mansfield is 8.25% on anything purchased. What is the percent of the original price you will pay? Write your answer as a percent, decimal, and fraction.)

Answers

If the tax was 10%, then you’d end up paying the original 100% plus the additional 10% tax, so you’d pay 110% of the original price.

In your example, it’s the same, except you have 8.25% tax, so you’d pay 100%+8,25% or 108.25% of the original price.
That’s stated as a percent.

To convert a percent to a decimal, you divide by 100:
108.25 ÷ 100 = 1.0825

To convert a decimal to a fraction, you have to know the place value of the smallest place. In this case, the 5 is in the ten thousandths place.
10825/10000

You can always double check that fraction on a calculator.

Point F is on line segment EG. Given FG = 3x – 5, EF = x, and
EG = 5x – 8, determine the numerical length of FG.

Answers

A line segment can have one or more points on it. The numerical length of FG is 4

Given that:

[tex]FG = 3x - 5[/tex]

[tex]EF = x[/tex]

[tex]EG = 5x - 8[/tex]

Because point F is on EG, then:

[tex]EG = EF + FG[/tex]

So, we have:

[tex]5x - 8 = x + 3x - 5[/tex]

[tex]5x - 8 = 4x - 5[/tex]

Collect like terms

[tex]5x - 4x = 8 - 5[/tex]

[tex]x =3[/tex]

Recall that:

[tex]FG = 3x - 5[/tex]

Substitute [tex]x =3[/tex]

[tex]FG = 3 \times 3 - 5[/tex]

[tex]FG = 9 - 5[/tex]

[tex]FG = 4[/tex]

Hence, the numerical length of FG is 4
