Answers

Answer 1

Answer:

m<6=77°

Step-by-step explanation:

Because the angles marked 3x+5 and 4x+7 are same side exterior angles, they are supplementary, meaning that

3x+5°+4x+7°=180°

7x+12°=180°

7x=168°

x=24°

Because the angles marked 6 and 3x+5 are corresponding angles, they are congruent, so:

<6=24*3+5

<6=77°

Westin performed an experiment in which he randomly pulled a marble from a bag, recorded its color, put it back, and then repeated. He did this 36 times, and 9 of those times he pulled a purple marble.

Which bags of marbles are good models for this experiment?

Select two that apply.

A ) 4 purple, 5 blue, 2 green, 1 red

B ) 4 purple, 5 blue, 2 green, 1 red

C ) 9 purple, 9 red, 9 green

D ) 9 purple, 9 red, 9 green

E ) 1 purple, 1 blue, 1 green, 1 red

F ) 1 purple, 1 blue, 1 green, 1 red

G ) 4 purple, 4 blue, 4 yellow, 4 orange

Answers

Answer:

Step-by-step explanation:

Based on the experiment, 9 times he pulled a purple marble out of the 36 trials.

That means he has a 1/4 probability of pulling a purple marble

This means that the purple marble ideally makes up one-quarter of the total marble in the bag.

Choice G and F satisfy the condition as stated above.

Hope that helps!

G) 4 purple, 4 blue, 4 yellow, 4 orange

there is 80 people how many people will there be if there was 75% more people?

Answers

Answer:

we have to add 75% of 80 into 80

so 75% of 80 is 60

now add 60 into 80 we get

80 + 60 = 140

so new population is 140

Answer:

Step-by-step explanation:

Note that 1.75 = 1.00 + 0.75.  The 1.00 is the original amount and the 0.75 the increase.  To answer this question, multiply (80 people) by 1.75:  140

140 is the final number of people.

Solve following proportions

Answers

Answer:

s = 6

Step-by-step explanation:

[tex]\frac{21}{14} =\frac{s}{4}[/tex]

1- cross multiply

21 x 4

= 84

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

14 x s

= 14s

SO..

14s = 84

2- to find 's' divide both sides by 14

[tex]\frac{14s}{14} = \frac{84}{14}[/tex]

s = 6

s=6
21/14 simplified is 3/2 after you divide by 7. now you need to find a fraction that is equal to 3/2 with a denominator of 4. to do this you multiply both numbers in the fraction 3/2 by 2. you get 6/4. s=6.

The variables x and y have a proportional relationship, and y= 5/6 which equation represents this relationship? x= 3/4. Which equation represents this relationship?

Answers

Answer:

(d)  y= (1 1/9)x

Step-by-step explanation:

A proportional relation is described by the equation ...

 y = kx

Dividing by x shows how to find the value of k:

 k = y/x

For the given values of y and x, the value of k is found to be ...

 k = (5/6)/(3/4) = (5/6)(4/3) = 20/18 = 10/9 = 1 1/9

The relationship is represented by the equation ...

 y = (1 1/9)

Five students came for after-school tutoring. Lin’s teacher assigned each of them the same number of problems to complete. Then he assigned each student 2 more problems. 30 problems were assigned in all.

Answers

Answer:

Equation: 5x + 10 = 30

Simplified Equation: 5x = 20

Number of problems assigned per person (at the start): 4

Total number of problems assigned per person: 6

Step-by-step explanation:

Hello!
We know that there were 5 students at the after-school tutoring and that the same number of problems were assigned to each person.

Let x = # of problems assigned to each student.

Since there were 5 students, x is multiplied by 5 so we can represent that as 5x

Next, 2 problems were assigned to each of the 5 students, so that can be represented as 5*2 or 10

If we add both values, they should equal to 30:

5x + 10 = 30

Simplified version: 5x = 20

Value of x : 4

On average, a largemouth bass weighs about 12 pounds. Two fishermen weighed the largemouth bass they both caught and found their catch weighed 82 pounds. What is the greatest number of largemouth bass caught that are average weight?

Answers

82÷12=6.833333333333

The greatest number of largemouth bass caught is 6.

What is Average?

In mathematics, the central value of a set of data is expressed as the average of a list of data. It is defined mathematically as the ratio of the total number of data points to the number of units in the list. In terms of statistics, the term "mean" also refers to the average of a certain set of numerical data.

As per the given data:

Average weight of largemouth bass = 12 pounds

Weight of all largemouth bass caught = 82 pounds

n = number of largemouth bass

Average = (Sum of all observations / Number of observations)

Average weight = (Average weight of largemouth bass / n)

12 = (82 / n)

n = (82 / 12)

n = 6 {considering only integer value}

Hence, the greatest number of largemouth bass caught is 6.

Answer:

20(x+3) = 310

The sum of the measures of angle Y and angle Z is 180 degrees. Angle Y measures (3x + 20) degrees and Angle Z measures x degrees.

A.) write an equation and solve for the value of x.

B.) what is the measure of each angle?

Answers

A)
The question tells us that
y + z = 180
And
y=3x+20
z=x

So we put them in the first formula:

y + z = 180
(3x + 20) + x = 180

Add and get x to one side:
4x + 20 = 180
4x + 20 - 20 = 180-20
4x = 160
Divide both sides by 4
x = 40

B)
Put x back in to equation to get size of each angle:

Y =3x +20
Y=3(40)+20
Y=120+20
Y=140

Z=x
Z=40

Verify: y+z=180
140+40=180
180=180

Add the two equations together to get:

Solve for y by dividing both sides by 4:

Y = -1

Now you have a value for y, solve for x in the first equation:

2x + 3(-1) = 7

2x -3 = 7

Add 3 to both sides:

2x = 10

Divide both sides by 2:

X = 5
