Simplify the expression below:
(7y^2-3y)-(4y^2+2y-2)

Answer:

If he spends $52.50 on 5 bags, add $16.50 to $52.50 and get $69.

Answer:

cone volume=(1/3)hpir^2

d/2=r

d=12

d/2=12/2=6=r

V=120pi

120pi=(1/3)hpi6^2

120pi=(1/3)hpi36

120pi=12hpi

divide both sides by pi

120=12h

divide 12

10=h cm

if height and diameter is doubled aka height and radius are doubled

V=(1/3)(2h)pi(2r^2)

we want to see how it compares to V=(1/3)hpir^2

V=(1/3)(2h)pi(2r^2)

V=2(1/3)(h)pi4r^2

V=8((1/3)hpir^2)

the volume is increased by 8 times

blanks are

Step-by-step explanation:

Answer:

The height of the container is 10 centimeters. If its diameter and height were both doubled, the container's capacity would be 8 times its original capacity.

Answer:

f(−10) =  ⇒ -19

f(2) =  ⇒ 4

f(−5) =  ⇒ -9

f(−1) =  ⇒ 1

f(8) =  ⇒ -5

Step-by-step explanation:

Answer:

-5

Step-by-step explanation:

y- 1/5x = 7

y= 1/5x +7

So, the slope of the line is 1/5

Perpendicular slopes are always the reciprocal with an inverse sign.

So, -5

Answer:

$1400

double is $2800

Step-by-step explanation:

$35,000 x .04 = $1400

if sales double, the commis soon will double so $1400 x 2 = $2800

Answer:

6:9

Step-by-step explanation:

the answer is 6:9 because 4:6' equivalent is 2:3, which is the same as 6:9

Answer:

d

Step-by-step explanation:

the answer is 12% decrease in area

The required, percentage decrease in the area of the triangle is 12%. Option D is correct.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
Area of the triangle = 1/2bh

Now,
The length of the base of a triangle is increased by 10 percent and the height is decreased by 20 percent,
base = b + 0.1b = 1.1b
height = h - 0.2h = 0.8h

New area = 1/2[1.1b][0.8h] = 0.88 [1/2b/h]

Percentage decrease in area = [ 1/2bh - 0.88 [1/2b/h] / 1/2bh × 100%
                                             = 12%

Thus, the required, percentage decrease in the area of the triangle is 12%. Option D is correct.

Answer:

the third one is correct

explanation:

the second dot on the graph shows that it is ten gallons of water for 2 minutes, making the fraction 10/2. That simplifies to 5/1, which is the third answer.

Answer:

4.72 in.

Step-by-step explanation:

BC = 3.1 in.

CD = 7.2 in.

Altitude of right triangle altitude is given as [tex] h = \sqrt{xy} [/tex], where:

h = altitude

x = 3.1 in.

y = 7.2 in.

Plug in the values into the formula

[tex] h = \sqrt{3.1*7.2} [/tex]

[tex] h = \sqrt{22.32} [/tex]

[tex] h = 4.72 in. [/tex] (nearest hundred)

Answer:

he should be making $306.25

Step-by-step explanation:

what i did was multiply his $8.75 a dog by 5 then multiply it by the 7 weeks

Answer:

Chris's total earning will be: $306.25

Step-by-step explanation:

Given:

Total number of dogs = d = 5

Number of weeks = w = 7

Cost for walking per dog = c = $8.75

First of all, we will calculate his per week cost of walking 5 dogs

Per week cost of walking 5 dogs = d*c = 8.75*5 = $43.75

Then for the cost of 7 weeks, the amount of one week will be multiplied by 7

Total earning will be:

[tex]= 43.75*7 = 306.25[/tex]

Hence,

Chris's total earning will be: $306.25

Answer:

43

Step-by-step explanation:

3x + 10 = 5x - 12

       10 = 2x - 12

      22 = 2x

        x = 11

check:

33 + 10 = 55 - 12

43 = 43

correct

x = 11 so bring this into 3x + 10

we get 43
