A biologist estimates that the human body contains 90 pounds of water for every 100 pounds of body weight. At the rate estimate the number of pounds of water in a child who weighs 80 pounds

Answer:

The answer is 2

All lines that are parallel have the same slope

Answer:

the slope is (2)

Step-by-step explanation:

Two lines that are parallel to each other have the same slope so,

the equation y=2x+5 is in the form y=mx+c

where m is the slope of the line so if we compare both equations we can see that the slope of the line given will be 2 and therefore, the slope of the line parallel to it will be the same (2)

Answer:

$3.29

Step-by-step explanation:

You need to find the unit price by dividing the cost by the amount.

24.33/7.4 = 3.29

Therefore, one pound of ham is $3.29.

Answer:

122 adults

Step-by-step explanation:

1049.20(price of tickets sold)÷8.60(ticket price per adult)=122

Answer:

A

Step-by-step explanation:

12x² - 7y² - 10x² + y² = 12x² - 10x² - 7y² + y²

                                 = (12 - 10)x² + (-7 + 1)y²

                                  = 2x² + (-6y²)

                                  = 2x² - 6y²

Answer:

Step-by-step explanation:

The formula of a distance between two points

[tex]A(x_A;\ y_A);\ B(x_B;\ y_B)\\\\|AB|=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}[/tex]

We have

[tex]A(3;\ 7);\ B(-5;\ -8)[/tex]

Substitute

[tex]|AB|=\sqrt{(-5-3)^2+(-8-7)^2}=\sqrt{(-8)^2+(-15)^2}\\\\=\sqrt{64+225}=\sqrt{289}=17[/tex]

Answer:

53 degrees

Step-by-step explanation:

Complimentary angles are angles whose sum equals 90 degrees.

90-37 = 53

Answer:

m∠RPQ = 53°

53 degrees

Step-by-step explanation:

When two angles are complementary angles, it means they add up to 90 degrees (Ex: a 10° angle and 80° angle would be complementary).

Therefore, if ∠SPR and ∠RPQ are complementary, then

m∠SPR + m∠RPQ = 90°

since you are given that m∠SPR = 37°, you can plug that in for m∠SPR to find m∠RPQ:

m∠SPR + m∠RPQ = 90°

37° + m∠RPQ = 90°

m∠RPQ =  90° - 37°

m∠RPQ = 53°

Answer:

Step-by-step explanation:

is easy and no hard

Answer:

12

Step-by-step explanation:

18 - 2r and 4r are the same length so the equation would be:

18 - 2r = 4r

Move the 2r to the other side

18 = 6r

Divide it by 6 to get r by itself

r = 3

Answer:

[tex]x = \frac{360}{11} [/tex]

[tex]y = \frac{60}{11} [/tex]

Step-by-step explanation:

Since 6y=x plug 6y in for x on the top equation.

[tex]2(6y) - y = 60[/tex]

[tex]12y - y = 60[/tex]

[tex]11y = 60[/tex]

[tex]y = \frac{60}{11} [/tex]

Plug y=60/11 into 6y=x

[tex]6( \frac{60}{11} ) = x[/tex]

[tex] \frac{360}{11} = x[/tex]

Plug 360/11 into 2x-y=60

[tex]2( \frac{360}{11} ) - \frac{60}{11} = 60[/tex]

[tex] \frac{720}{11} - \frac{60}{11} = 60[/tex]

[tex] \frac{660}{11} = 60[/tex]

The identity is true

Answer:

5/2

Step-by-step explanation:

Answer:

5/2 is the largest fraction.

Step-by-step explanation:

To find the largest fraction, we can convert some using the LCD (least common denominator)

Keep 5/6 as is.

1/3 = 2/6

3/2 = 9/6

5/2 = 15/6

So, 5/2 is the largest fraction.
