b

Step-by-step explanation:

hi I I'm the explanation

Answer:

Thats what i got too :)

Step-by-step explanation:

You have the correct answer. It is 80.3 square yards.

Work Shown:

Area of parallelogram = length*width = 21.5*33.6 = 722.4 sq ft

1 yard = 3 ft

1 sq yd = 9 sq ft ... square both sides

To convert from square feet to square yards, we'll divide by 9

This is the same as multiplying by 1/9

722.4 sq ft = (722.4 sq ft)*(1 sq yd/9 sq ft)

722.4 sq ft = (722.4)*(1/9) sq yards

722.4 sq ft = 80.2667 sq yards

722.4 sq ft = 80.3 sq yards

Answer:

p = -4

Step-by-step explanation:

I'm not going to explain each step, just try to follow along.

31 = -(1+6p)+4(p+6)

31 = -1-6p+4p+24

7 = -1-2p

8 = -2p

p = -4

Answer:

-3x

Step-by-step explanation:

Answer:

Step-by-step explanation:

If we multiply any negative number in this case -3 times a POSITIVE we will always get a negative. So the positive we can put as x and multiply -3 times x = -3x.

Hope this helps :D

y(x)=4x

y(x)=4

<=>4x=4

<=>x=1

Answer:

direct

Step-by-step explanation:

The standard form of an equation representing direct variation is

y = kx ← k is the constant of variation

The standard form of an equation representing inverse variation is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

y = - [tex]\frac{2}{5}[/tex] x ← represents direct variation with k = - [tex]\frac{2}{5}[/tex]

Answer:

14 girls

Step-by-step explanation:

I hope this helps!

Answer:

14 girls in the class

Step-by-step explanation:

use percentage equation, p = nw or part of the question = the percentage times the total amount.

So in this case our p, or girls in the class (which is part of the total), is unknown. We have the percentage and we have the total. So all we need to do is multipy them. However how do you multiply percentage . . . well 40 percent also equalts to 0.40. So all you have to do is multiply .40 by 35 and you have your answer.

Answer:

the first questions answer is yes the seconds is no

HAVE A NICE DAY!!!

Answer:

6x+8y = 3

Step-by-step explanation:

we have 3x + 4y = 7

4y = -3x + 7

y = -3/4 x + 7/4

so slope is -3/4

2 parallel lines always have same slope

so the slope of our new line is -3/4

so y = -3/4 x + C

for c,

we have (x,y) = (-2/3,7/8)

7/8 = -3/4 * -2/3 + C

C = 3/8

so equation is

y = -3/4 x + 3/8

simplyfyig,

8y = -6x + 3

or, 6x+8y = 3

Answer:

Subtract 3

-6x = 42

Divide by -6

x = -7

Answer:

∠ B ≈ 62.73°

Step-by-step explanation:

Using the sine ratio in the right triangle.

sinB = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{8}{9}[/tex] , thus

∠ B = [tex]sin^{-1}[/tex] ([tex]\frac{8}{9}[/tex] ) ≈ 62.73° ( to the nearest hundredth )

Answer:

6A7C8B

Step-by-step explanation:

Add them in and try to solve for 7 and 6, for 8. I usually put all number on one side and all x on other side.

Answer:

(a) TRUE

(b) TRUE

(c)  FALSE

(d) TRUE

Step-by-step explanation:

" The "opposite" of any number is also known as it's " additive inverse" i.e. for any number 'a' the additive inverse is 'a' ".

(a) TRUE

Since let us consider any negative number '-5' then it's opposite is '5' since (-5)+5=0

(b) TRUE

this could be seen clearly from the number line.

(c) FALSE

this statement is false since we can take example of zero.

the opposite of zero is 0 but 0×0≠1.

(d) TRUE

since 0-0=0.Step-by-step explanation:

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

Step 1: Define

f(x) = 2x + 1

g(x) = x² - 7

(f - g)(x) is f(x) - g(x)

Step 2: Solve

Answer:

20x^5

Step-by-step explanation:

You just multiply 5 by 4 and get 20 and when multiplying exponents you just add them together so you get 20x^5

THE BEST ANSWER IS C>>>>>>>>>>>>

Answer:

5. 3050ft³ (rounded to 3 s.f.)

6. 4190ft³(rounded to 3 s.f.)

7. 4600ft³(rounded to 3 s.f.)

Formulas (For easier reference):

Volume of a cone: pi×r²×[tex]\frac{h}{3}[/tex]

Volume of cylinder: pi×r²×h

Volume of a sphere: [tex]\frac{4}{3}[/tex]×pi×r³

Volume of a hemisphere: [tex]\frac{2}{3}[/tex]×pi×r³

Step-by-step explanation:

You can just apply the formulas to the question:

5. Volume of cone = pi×9²×[tex]\frac{(16-10)}{3}[/tex]

                               = 162pi

  Volume of cylinder = pi×9²×10

                                   = 810pi

Volume of figure = 162pi+810pi

                            = 972pi

                            = 3050ft³ (rounded to 3 s.f.)

6. Volume of sphere = [tex]\frac{4}{3}[/tex]×pi×10³

                                   = 1333[tex]\frac{1}{3}[/tex]pi

                                   = 4190ft³(rounded to 3 s.f.)

7. Volume of hemisphere = [tex]\frac{2}{3}[/tex]×pi×(26÷2)³

                                          = 1464[tex]\frac{2}{3}[/tex]pi

                                          = 4600ft³(rounded to 3 s.f.)

Answer:

The number 11 is not a solution for the given equation.

Step-by-step explanation:

We are given an equation with one variable. We can use simplifying processes to solve the equation.

[tex]3(x+6)=4x \ \ \text{Distribute the 3 through.}\\3x + 18 = 4x\ \ \ \text{Flip the equation.}\\4x = 3x + 18 \ \ \ \text{Subtract 3x from both sides.}\\\small\boxed{\bold{x = 18}}[/tex]

We can also substitute 11 for x and solve to see if the left side and right side of the equation equals itself.

[tex]3(11 + 6) = 4(11)\\33 + 18 = 44\\\small\boxed{\bold{51 \neq 44}}[/tex]

Therefore, 11 is not a solution for the given equation.

Answer:

[tex] \displaystyle \rm \longmapsto \:3(x + 6) = 4x[/tex]

[tex] \displaystyle \rm \longmapsto \:3x + 18 = 4x[/tex]

[tex] \displaystyle \rm \longmapsto \:4x = 3x + 18[/tex]

[tex] \displaystyle \rm \longmapsto \:4x - 3x = 18[/tex]

[tex] \displaystyle \rm \longmapsto \:x = 18[/tex]

[tex] \displaystyle \rm \longmapsto \:3(11 + 6) = 4(11)[/tex]

[tex] \displaystyle \rm \longmapsto \:33 + 18 = 44[/tex]

[tex] \displaystyle \rm \longmapsto \:51 = 44[/tex]

Answer:

10 : 12 is equivalent to 5 : 6 and 20 : 24.

Step-by-step explanation:

You can divide and multiply the ratio by 2 to get an equivalent ratio.

The ratio which is equivalent to 10: 12 are 5: 6 and 20: 24 Therefore, option (C) will be correct.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

As per the given ratio, 10:12.

Divide numerator and denominator by 2

(10/2):(12/2) = 5:6.

Multiply the numerator and denominator by 2

(10×2);(12×2) = 20:24

Hence "The ratio which is equivalent to 10: 12 are 5: 6 and 20: 24".
