Answer:

y = 5 ft

Step-by-step explanation:

We are looking for y.

This is a right triangle, so we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

a = 12 and b = y c = 13

12^2 + y^2 = 13^2

144 + y^2 =169

Subtract 144 from each side

144-144 +y^2 = 169-144

y^2 = 25

Take the square root of each side

sqrt(y^2) = sqrt(25)

y = 5

Answer:

(-1, 5) and (3, -3)

Step-by-step explanation:

The solutions are all the points where the two functions intersect. Since the lines intersect at two different points, there are two solutions.

The two points at which the functions appear to intersect are (-1, 5) and (3, -3).

The product of two rational numbers is -12 if one of the number is -8 find the other

evablogger [386]

Answer:

The other number is $\frac{4}{3}$

Step-by-step explanation:

The product of two rational numbers, x and -8, is -12. This means that:

$-8x = -12$

The other number is x, which we find solving the equation. So

$8x = 12$

$x = \frac{12}{8} = \frac{4}{3}$

The other number is $\frac{4}{3}$

Candace ate 3 over 4 cup of cereal. The box of cereal states that one serving of cereal is equal to 2 over 3 cup. Which fraction

choli [55]

Answer: Candace ate $\dfrac9{12}$ servings.

Step-by-step explanation:

Given: Candace ate $\dfrac34$ cup of cereal.

The box of cereal states that 1 serving of cereal = $\dfrac23$ cup.

i.e. 1 cup = $\dfrac32$ servings [Multiply $\dfrac32$ both sides]

⇒ $\dfrac{3}{4}$ cup = $\dfrac34\times\dfrac32$ servings

= $\dfrac9{12}$ servings [which is the number of servings she ate]

Hence, Candace ate $\dfrac9{12}$ servings.
