Find the missing side of each triangle. Leave your answers in simplest radical form.
QveST [7]

Answer:

Missing side = 12.04mi /√145mi.

Step-by-step explanation:

<h3>Given :- </h3>

Perpendicular = 9 mi

Base = 8 mi

And Hypotenuse = missing side = x

<h3>Solution :- </h3>

Now substitute the values

➟ ( 9 mi ) ² + ( 8 mi ) ² = x²

Simplify the values

➟ 81 mi ² + 64 mi ² = x ²

Add the values

➟ 145 mi ² = x ²

Finding , the root of 145 mi ²

➟ √145 mi ² = x

➟ 12.04 mi = x

Therefore, The missing side of the triangle is 12.04 mi / √145 mi.

Kasey and Jordan are counting calories while eating lunch in the school cafeteria. in one week, Kasey had 10 slices of pizza and
svetoff [14.1K]

Answer:

222 calories from the pizza

Step-by-step explanation:

nandhini123-

Given:

slices of pizza ate by Kasey =10

cups of fruit salad by Kasey=  5

slices of pizza ate by Jordan = 6

cups of fruit salad by Jordan=  7

Kasey's calorie  count = 3070

Jordan calorie  count = 2522

To Find:

calories Jordan got from pizza =?

Solution:

Let the calorie of one slice of pizza be  x

and the  calorie of one cup of fruit salad be  y

According to the question, the equation that represents the Kasey's Scenario is

10x + 5y = 3070-------------------------------------(1)

Similarly the equation that represents the Jordan Scenario is

6x + 7y = 2522--------------------------------------(2)

multiply eq(1) by 6 we get

60x + 30y = 18420---------------------------------(3)

multiply eq(2) by 10 we get,

60x + 70y = 25220----------------------------------(4)

Subtracting eq (3) from (4) we get

 60x + 70y = 25220

 60x + 30y = 18420

 (-)        (-)        (-)

-----------------------------------

0x + 40y = 6800

---------------------------------

=>40 y = 6800

=>y =

=> y = 170

So calorie of one cup fruit salad is = 170 calories

substituting the y values in eq 1 we get

10x + 5(170) = 3070

10x + 850 = 3070

10x = 3070 - 850

10x = 2220

x =

x= 222

So calorie of one pizza slice = 222 calories

Now we know that  Jordan ate 6 slices of pizza

calories  Jordan get from pizza = number of pizza he ate  X calore per pizza slice

=> 6 x 222

=>1332 calories

Which expression is equivalent to 6 Superscript 4 times 6 cubed? (6 times 6 times 6 times 6) (6 times 6 times 6) (6 6 6 6) times
malfutka [58]

The expression which is equivalent to 6 Superscript 4 times 6 cubed and posses same value as this expression is,

6\times6\times6\times6)\times6

<h3>What is the equivalent expression?</h3>

Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.

The given statement for the expression is 6 Superscript 4 times 6 cubed. This expression cab be written as,

6^4\times6

Suppose the equivalent expression of this equation is n. Thus,

n=6^4\times6

The 4 power of number 6 means that the number 6 should be multiplied 4 times.

n=(6\times6\times6\times6)\times6

Hence, the expression which is equivalent to 6 Superscript 4 times 6 cubed and posses same value as this expression is,

6\times6\times6\times6)\times6
