if possible,find the missing side length labeled with a question mark. if not possible, explain why. on the left at here are 6 inches 6 inches twice . inside the triangle there are 36 inches 36 inches twice. and the in the bottom there is 20 inches

Answers

Answer:

10 inches

Step-by-step explanation:

They're 36 degrees, so corresponding angles are the same, so the middle line is parallel to the bottom line of the triangle.

But the middle line bisects one of the waist lines of the triangle, so this is the middle line, which is equal to half the length of the bottom line

The answer is 10 inches :3

Someone please help. Explain why it might be easier to solve the multiplication problem by changing it from this: 5×98×2 , to this: 5×2×98 . Use a property of multiplication to justify your reasoning.

Answers

Answer:

Because it is easy to multiply 5 by 2 which is 10......and then 10 × 98 youbjust have to add 0 to 98.....which will be 980

The multiplication problem can be simplified by the equation A = 5 x 2 x 98 and the value of A = 980

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = 5 x 98 x 2

On simplifying , we get

From the associative property , we get

A = ( 5 x 2 ) x 98

where the value of 5 x 2 = 10

So , the multiplication expression is

A = 10 x 98

A = 980

Therefore , the value of A is 980

Hence , the equation is A = 980

Which of the following represents, the difference of a number squared and four is less than or equal to five.

Answers

Answer:

x² - (4 ≤ 5)

Step-by-step explanation:

(I have x representing the number that is squared, it might be a different letter on your options, but regardless it will be the same general answer. You also may not need the parentheses around the 4 ≤ 5)

Difference means subtraction so we know that the second number/group of numbers will be subtracted from the first that is listed.

Next, if you are squaring any number it's going to have the little 2 to the right of it. That's what that means.

Then, we look at that last bit. "Four is less than or equal to five." This means exactly how it sounds. To write this we need the symbol ≤. This symbol means less than or equal to. You would would but the 4 in front and the 5 in back to get 4 ≤ 5.

Now we just put it together. It tells us that 4 ≤ 5 is being subtracted from a number squared. So this means that a number squared needs to be first, and because difference means subtraction, we would subtract 4 ≤ 5 from that. A number squared can be represented by any letter variable, but for this example, I will use x.

This leaves you with x² - (4 ≤ 5)

I hope this helped :)

Based on her recipe, Elena knows that 5 servings of granola have 1,750 calories.
1. If she eats 2 servings of granola, how many calories does she eat?
2. If she wants to eat 175 calories of granola, how many servings should she eat?
3. Write an equation to represent the relationship between the number of calories and the number of servings of granola.

Answers

Answer: 350 Calories

Step-by-step explanation:

I did this in school hope this helps!

1. 1750/5=350 (to find out how many calories for 1 bar) 350*2=700
2. 300=1 serving and since you want 175 you set up a faction so you will have 300/1 = 175/? Then you would cross multiple and divide so 175*1= 175 and then divided 175/300= about 0.6 servings

A basket contains 3 apples and 7 oranges. A fruit is drawn and put back into the basket. This process is repeated 3 times. What is the probability that selected three fruits are orange? **Please answer in fractions only!**

Answers

Answer:

the fraction of oranges in the basket would be 8/15 because we have 8 oranges and 15 fruits in total

Step-by-step explanation:

The probability for selection orange thrice from basket is 343/100.

What is the definition of the probability?Probability is synonymous with possibility. It is a mathematical branch that deals with incidence of a random event. The value ranges from zero to one. Probability has just been introduced in mathematics to predict the likelihood of events occurring.

A basket contains 3 apples and 7 oranges.

Total fruits = 10.

A fruit is selected from the basket three times with replacement.

The probability for the selection of one orange is 7/10.

The probability for the selection of second orange is 7/10.

The probability for the selection of third orange is 7/10.

Thus, the probability for selection orange thrice is;

Probability (3 times orange) = 7/10×7/10×7/10

Probability (3 times orange) = 343/100

Thus, the probability for selection orange thrice from basket is 343/100.

An orchard sells apples in 5.5‐pound bags. The orchard sells 65 bags of apples each day.

How many pounds of apples does the orchard sell in 1 week?

The orchard sells
pounds in 1 week.

Answers

Answer:

2502.5 pounds

Step-by-step explanation:

Answer:

2,503 pounds

Step-by-step explanation:

Multiply the amount of bags sold by the number of days within a week.

65 x 7 = 455

In 1 week 455 bags of apples are sold.

The next step is to multiply the total amount of bags sold in 1 week by the pound of 1 bag of apples.

455 x 5.5 = 2,502.5lbs

2,503lbs (rounding to the nearest whole number) of apples are sold in 1 week.
