PLSSSSSS HELPPP!!! FASTTTTTTT

Answer:

in the explanation

Step-by-step explanation:

rs=2^2+4^2=20cm

sq root of 20=4.472135955 (round down to how much you like, probably 1dp)

qt=4^2+8^2=80cm

sq root of 80= 8.94427191

for the other pic just do [tex]\sqrt{80}[/tex] takeaway [tex]\sqrt{20}[/tex], which is 4.472135955 and round down to how much u like

Answer:

39

Step-by-step explanation:

2x5=10

10+3=13

13x3=39

Answer:

39

Step-by-step explanation:

First since f=5 , you should get rid of the f

2 * 5 = 10

so now the equation is 3(10+3)

Then you add the numbers in the parentheses

10 + 3 = 13

Then multiply it by 3

3 * 13 = 39

39 is your answer

Answer:

19: The difference between the temperature in Fair Banks and Barlow is 3°F

20: -13°F, -10°F, 15°F, 24°F.

Step-by-step explanation:

I'm assuming that by "compare", it means to find the difference between temperatures in question 19. If it means something else, let me know and I'll try and help you find it.

Answer:

for 19 is the difference between the temperature in Fairbanks and Barlow is 3°F and for 20 is -13°F, -10°F, 15°F, 24°F.

it means to find the difference between temperatures in question 19 i guess that helps. 0-o

Answer:

1/4

Step-by-step explanation:

got it right on test

Answer:

Step-by-step explanation:

1.

P(A) = 1/6, P(B) = 1/2

P(A and B) = 1/6*1/2 = 1/12

2.

P(A) = 1/6

P(B) = 1/6

P(A and B) = 1/6*1/6 = 1/36

3.

P(A) = 2/6 = 1/3

P(B) = 1/3

P(A and B) = 1/3*1/3 = 1/9

4.

P(gold) = 4/7 for each

P(2 golds) = 4/7*4/7 = 16/49

5.

Remaining marbles:

P(green) = 2/5

Answer: Because Frank is planting x seeds in one and 4x+7 in the other, you need to add both of those together.

Answer:B or 540 cubic inches.

Step-by-step explanation:

So, if we multiplied all 3 values using the volume formula, we get 600 cubic inches. And if it says 90%, we multiply .9x600 and get 540 cubic inches.

Answer:

B. 540 cubic inches

Step-by-step explanation:

Let's start with the formula.

[tex]Volume=Length*Width*Height[/tex]

Or:

[tex]V=L*W*H[/tex]

We are given the Length, Width, and Height.

So we just multiply it out:

[tex]12.5*6*8=600[/tex]

The volume is 600 cubic inches

But we aren't done yet:

We now have to find 90% of 60, and we can do that in two ways

Set up a percent proportion:

[tex]\frac{x}{90}=\frac{600}{100}[/tex]

[tex]x=\frac{90*600}{100}[/tex]

[tex]x=540[/tex]

Or we could use benchmark fractions.

To find 90% of 600, we do 600 - (10% of 600)

This is just 600 - 60

540

Answer: 50

Step-by-step explanation:

5/9 (f-32) if f = 122 you take 122 and subtract 32 because of order of operations and now you have 5/9 (90) and then you multiply 5/9 times 90 and you get 50

Answer:

54

Step-by-step explanation:

30 percent * 180 =

(30:100)* 180 =

(30* 180):100 =

5400:100 = 54

Answer:

R= 1 1/12 or 13/12 I think that's the simplest form

Answer:

4[tex]\frac{7}{12}[/tex]

Step-by-step explanation:

Give make the fractions improper first!

3[tex]\frac{1}{4}[/tex] -> [tex]\frac{13}{4}[/tex]

1[tex]\frac{1}{3}[/tex] -> [tex]\frac{4}{3}[/tex]

Now give them the same denominator, making it easy to solve.

[tex]\frac{13(3)}{4(3)}[/tex] -> [tex]\frac{39}{12}[/tex]

[tex]\frac{4(4)}{3(4)}[/tex] - >[tex]\frac{16}{12}[/tex]

now add!

[tex]\frac{55}{12}[/tex] - > 4[tex]\frac{7}{12}[/tex]

Answer: 76

Step-by-step explanation:

well, we know that 15% of the X is 12, so we first use 6 15%, which is 90% 6X12=72. next, we would use 12/3, which is 4. 72+4=76.

Answer:

80

Step-by-step explanation:

12/x = 15/100

cross multiply

1200/15x; 1200/15 =80

x=80

Answer:

1. A, because 4(2)=8. 2 is the x.

2. B, because 2.5 x 4 = 10, which makes sense.

3. B, because 5x is the amount that you want to put into equal parts and the 3 is just being subtracted from the amount of the equal parts from the 5x.

4. C.
