Step-by-step explanation:

Arithmetic mean is simply the sum of the all the number present divide by the total number.

From the question, we obtained the following information:

The arithmetic mean = 5.6

Total number present = 10

Sum of the numbers =?

Arithmetic mean = sum of the numbers / total number

Sum of the numbers = arithmetic mean x total number

Sum of the numbers = 5.6 x 10 = 56

Answer:

Step-by-step explanation:

Average mean = 5.6

No. Of scores = 10

Mean = sum of no./ number of scores

Therefore 5.6 = sum of no. /10

Cross multiply

Sum of no. = 5.6 x 10

= 56

The sum of the number is 56

What is the product (9t-4)(-9t -4)

r-ruslan [8.4K]

Hey Tro2,

Lets find the product of your equation together,

The question we are encountering is : What is the product (9t-4)(-9t-4)?

Lets simplify this step by step, shall we.

$\left(9t-4\right)\left(-9t-4\right)$ : Equation

$\mathrm{Distribute\:parentheses\:using}:\quad \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd$ .

Where : $a=9t,\:b=-4,\:c=-9t,\:d=-4$ .

This leads to $9t\left(-9t\right)+9t\left(-4\right)-4\left(-9t\right)-4\left(-4\right)$ .

Now we have to $\mathrm{Apply\:minus-plus\:rules}$ .

Where: $-\left(-a\right)=a,\:\:\:\:+\left(-a\right)=-a$

$-9t\cdot \:9t-9t\cdot \:4+4\cdot \:9t+4\cdot \:4$

$=-81t^2+16$

Keisha swims 18 feet from one side of her circular pool to the other swimming straight through the center. She then swims one ti

Ket [755]

Answer:

56.5 ft

Step-by-step explanation:

Here we know that:

- Keisha swims 18 feet from one side of her circular pool to the other swimming straight through the center --> this means that the diameter of the swimming pool is 18 feet, so

d = 18 ft

- Then, she swims one time around the entire edge of her swimming pool. --> this means that she swims along the perimeter of the swimming pool

The perimeter of a circle is given by

$p=\pi d$

where d is the diameter. Therefore in this case, the length of Keisha's second swim is:

$p=\pi \cdot d = 3.14 \cdot 18 =56.5 ft$
