4 0

Answer:

A =36 ft^2

Step-by-step explanation:

The area of a trapezoid is given by

A = 1/2 ( b1+b2)h where b1 and b2 are the lengths of the bases

A = 1/2 ( 13+5) *4

A = 1/2 ( 18)*4

A =36 ft^2

Earl runs 30 meters in 20 seconds. How many meters does Earl run per second?
Karolina [17]
To answer this we will divide the amount of meters by the amount of seconds. Then your answer will be the amount of meters Earl runs per second. Then we will check our work. Lets do it:-

30 ÷ 20 = 1.5
1.5 meter per second.

CHECK OUR WOK:-

1.5 × 20 = 30
We were RIGHT!!

So, 1.5 meters per sec.

Hope I helped ya!!

What are the zeros of f(x) = x2 - 12x + 36?
topjm [15]

Answer:

c. x = 6 only

Step-by-step explanation:

In order to calculate the zeros of f(x), we need to set it equal to zero and find the corresponding values of x.

x^{2}-12x+36=0

Using the midterm breaking, we can split -12x into two such terms whose sum will be -12x and product will be 36x². These two terms are -6x and -6x

So, the above expression can be written as:

x^2-6x-6x+36=0\\\\ x(x-6)-6(x-6)=0\\\\ (x-6)(x-6)=0\\\\ (x-6)^{2}=0\\\\ x-6=0\\\\ x=6

This means, the zero of f(x) occurs at x = 6 only.

Choice B

Step-by-step explanation: Hello!

To find the length of KL, we will need to use the distance formula.

The distance formula is \sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2}}.

We are given K(4, 5) and L(4, -2), and we can find the distance between these two points through substitution.

\sqrt{(4-4)^{2} +(-2-5)^{2}}

\sqrt{(0)^{2} +(-7)^{2}}

\sqrt{(7)^{2}} = \sqrt{49} = 7

Therefore, the length of KL is 7 units, choice B.

Nancy can do a typing job in 8 hours, when Carole helps her, they can do the job in 5 hours. How many hours would it take Carole
galben [10]

Answer: \frac{40}{3}\ \text{hours}

Step-by-step explanation:

Nancy can do typing job in 8 hours

i.e. in 1-hour nancy can  \frac{1}{8} part of work

Together they can do that work in 5 hours

or in 1 hour \frac{1}{5} part of work is done

suppose Carole takes x hours for the work

so, in 1 hour \frac{1}{x} part is done

If both work together for 1 hour then we can write

\frac{1}{8}+\frac{1}{x}=\frac{1}{5}

\frac{1}{x}=\frac{1}{5}-\frac{1}{8}

x=\frac{40}{3}\ \text{hours}
