Answer and step-by-step explanation:

If it is a rectangle, the formula is:

L * W

Fill in the values:

4*6.9

Then solve.

27.6

So, if it is a rectangle, the answer is (C), 27.6 Inches squared.

If it is a triangle, the the formula is:

(B*H)/2

Fill in the values:

4*6.9/2

Simplify:

27.6/2

Then solve.

13.8

So, if it is a triangle, the answer is (A), 13.8 Inches squared

Hope this helps!

Aleka and Helene both opened savings accounts that earn 2.5% interest a year. Aleka puts $2,500 into her account. Helene put $1,

Xelga [282]

Given:

Amount in Aleka and Helene accounts represented by the following function:

Aleka: $f(x) = 2500(1.025)^x$

Helene: $g(x) = 1500(1.025)^x + 200x$

To find:

The function represents the difference, $h(x) = f(x) -g(x)$ , between the value of Aleka's and Helene's total savings after x years.

Solution:

We have,

$f(x) = 2500(1.025)^x$

$g(x) = 1500(1.025)^x + 200x$

Now,

$h(x) = f(x)-g(x)$

$h(x) = 2500(1.025)^x-[1500(1.025)^x + 200x]$

$h(x) = 2500(1.025)^x-1500(1.025)^x - 200x$

$h(x) = 1000(1.025)^x - 200x$

Therefore, the correct option is C.

The measure of angle DBE is (0.1x - 22) and the measure of angle CBE is (0.3x - 54). Find the value of x.

ElenaW [278]

The measure of angle DBE is (0.1x - 22) and the measure of angle CBE is (0.3x - 54). The value of x is 415

Step-by-step explanation:

Given that,

The measure of angle DBE (0.1x - 22)

The measure of angle CBE (0.3x - 54)

Step 1

As per the Angle Addition Postulate,

m∠DBE+m∠CBE=m∠DBC

Step 2

Since∠ DBC is a right angle as indicated by the square symbol, then m∠DBC=90°.

Hence,

(0.1x-22)+(0.3x-54)= 90

Step 3

Lets solve the equation for x

We know that 0.4x-76= 90

0.4x= 166

x=166/0.4

x=415

Step 4

Answer : The value of x is 415

The total cost in dollars to buy uniforms for the players on a volleyball team can be found using the function C equals 34.95 yo

ASHA 777 [7]

Answer:

8 ≤ u ≤ 12

Step-by-step explanation:

Given:

C = 34.95u +6.25

Where,

u = number of uniforms

what is the domain you of the function for this situation

The number of uniforms depend on the number of players

If there are at least 8 players but not more than 12 players on the volleyball team.

u ≥ 8

u ≤ 12

The domain of the function is

8 ≤ u ≤ 12
