Answers

Answer 1

Answer:

9) 7sqrt(2)

11) 8sqrt(2)

13) 3sqrt(7)

Step-by-step explanation:

9) factor the radicand 98 into 7*7*2, 7^2*2, and then factor out the 7 squared to the outside of the radical to get 7 square roots of 2

11) factor the radicand 128 into 8*8*2, 8^2*2, and then factor out the 8 squared to the outside of the radical to get 8 square roots of 2

13) factor the radicand 63 into 3*3*7, 3^2*2, then factor out the 3 squared outside of the radical to get 3 square roots of 7

Answers

Absolute Value can’t be negative so -3 minus -4 is -7 but since absolute value isn’t able to be negative it turns into 7, the answer is A

Answer:

The absolute value of -7 = 7

The absolute value of 7 = 7

So, D, both -7 and 7

Math question angles

Answers

m<1 = 131

m<2 = 49

m<3 = 131

<4 and <2 are vertical from each other and so are <3 and <1.

<4 and <1 are a linear pair and so are <2 and <3.

To get <1 do this

180 -49 = 131

m<1 = 131

m<3 = 131 because they are vertical from each other

m<2 = 49 since it is vertical from <4

Vertical from each other means that they are across from each other and have the same measure.

Linear Pair means that two angles on the same line will equal to 180.

Ex: m<1 = 131 & m<4 = 49

So 131 + 49 = 180 Linear Pair

Answers

Answer:

Tn = 2/3^(n-1)

Step-by-step explanation:

The nth term of a geometric progression is expressed as

Tn = ar^{n-1}

a is the first term

n is the number of terms

r is t common ratio

From the sequence

a = 2/9

r = (2/3)/(2/9) = 2/(2/3) =3

Substitute

Tn = 2/9(3)^(n-1)

Tn = 2/3^(n-1)

Hence the required equation is Tn = 2/3^(n-1)

Answer:

the actual answer is [tex]a_{n}[/tex][tex]=(\frac{2}{9} )3^{n-1}[/tex]

An experiment finds that runners with the longest legs complete a mile run in less time. Identify the relation between leg length and time of a mile run.

Answers

Answer:

The relation between the leg length and the time of a mile run is an inverse relation.

Step-by-step explanation:

Inverse relation is one between two variables in which as the value of one of the variables increases, then the value of the other decreases.

From the given question the longer the leg of a runner, the lesser the time to complete a mile run. This implies that as the length of the leg of a runner increases, the time to cover a mile decreases. Therefore, the relation between the leg length and time is an inverse relation.

In Mr. Snarey's class 8 out of 25 students are boys. What percentage are girls?

HELP!! PLEASE

Answers

25% I thinkkkkkkkkkkkkkk

First:

8 out of 25 students are boys.
Put that in fraction form

8/25

Now..

Turn that 25 into 100
So

8/25 = 32/100

25/25 is 100%
So
25/25 = 100/100

100/100 - 32/100 = 68/100

So 68% of the students are girls.

Jesse is a pizza delivery driver. Each day his employer gives him $20 plus $0.50 for every pizza that he delivers.

Write an equation that can be used to determine how much Jesse earns each day if he delivers x pizzas.

Answers

Answer:

Concept: Algebraic Representation

You have a daily pay or a y-intercept of 20 Then you have a variable change such that 0.50 is earned for each additional pizza Hence the representation is y=0.50x+20X represents pizzas sold and y represents total pay

Answer:

y=0.50x+20

X represents pizzas sold and y represents total pay

Select all the ratios that are equivalent to 4: 5.
14:27.5 2:2.5 3:3.75 2:3 8:10 7:8

Answers

Answer: All the ratios that are equivalent to 4: 5 are

2:2.5 3:3.75 and 8:10

Step-by-step explanation: You can check by making fractions of the ratios.

4/5 = 0.8

2/2.5 = 0.8 Also, the values are each half of the given ratio.

8/10 = 0.8 and the values are double the numbers in the given ratio.

3:3.75 this one is not obvious at first, but each value is .75 or 3/4 of the numbers in the given ratio, and it passes the decimal equivalency test:

3/3.75 = 0.8

The ratios that equivalent to 4 : 5 are given as 2:2.5, 3:3.75 and 8:10 respectively.

What is the ratio of two numbers?

The ratio of two numbers a and b can be written as a : b = a/b.

The ratio of two quantities is the unit rate of one quantity with respect to the other.

In order to find the equivalent ratio cross multiplication is done as follows,

(a) 4: 5 and 14:27.5
