Mason misses 25% of the free throws he attempts in a season. How many total free throws did he attempt if he missed 52?

Answers

Given:

Mason misses 25% of the free throws he attempts in a season.

Number of missed free throws = 52

To find:

The total number of free throws.

Solution:

Let x be the total number of free throws.

Mason misses 25% of the free throws he attempts in a season.

Number of missed throws = 25% of x

Number of missed free throws = 52

Now,

[tex]\dfrac{25}{100}x=52[/tex]

[tex]\dfrac{1}{4}x=52[/tex]

Multiply both sides by 4.

[tex]x=52\times 4[/tex]

[tex]x=208[/tex]

Therefore, the total number of free throws is 208.

2. Which equation is equivalent to 2 + 4x = 5 - 3(x + 1)? A. 2 + 4x = 2x - 3 B. 2 + 4% = 5 - 3 -3. C. 6x = 5-(+ 1). D. 2 + 4 = 2/5 1).​

Answers

Answer:

B) 2 + 4x = 5 - 3 - 3x

Step-by-step explanation:

By simplifying JUST the right side and re-arranging them

2 + 4x = 5 - 3(x + 1),

2 + 4x = 5 - 3x -3,

2 + 4x = 5 -3 - 3x

f (x) = x + 5 and g(x) = 2x Find (f +g)(x)

Answers

Step-by-step explanation:

f(x)=x+5 and g(x)=2x

(f∘g)(x)=f(g(x))=f(2x)=5+(2x)=2x+5

(g∘f)(x)=g(f(x))=g(x+5)=2(x+5)=2x+10

(f∘g)(x)=2x+5

(g∘f)(x)=2x+10

Glen, Andre, and Ramón share the cost of renting a vacation cottage. The total cost is $960. Glen pays 30% of the total cost. Andre pays 0.45 of the total cost. Ramón pays the rest. How much does Ramón pay?

Answers

Answer:

Ramon pays $240.

Step-by-step explanation:

30% of $960 is $288, so Glen pays $288

0.45 = 45%

45% of $960 is $432, so Andre pays $432

30% + 45% = 75% meaning Ramon pays 100% - 75% which is 25%.

25% of $960 is $240. So, Ramon pays $240.

You could also add up the payments of Andre and Glen and subtract that sum from $960 to get the same answer.

find the glide reflection image of the image of the black triangle for the composition

Step-by-step explanation:

The glide reflection of the figure is given below. Therefore, option D is the correct answer.

What is a glide reflection?

Glide Reflection is a composition of transformations. In glide reflection, a translation is first performed on the figure then it is reflected over a line.

From the given figure, labelled the black triangle as A, B and C.

The coordinates of  triangle ABC are; A= (2,8) , B= (2,5) and C=(6,5)

To find the glide reflection image of the triangle ABC.

Given: The rule of translation is: (x, y)→(x, y-7) and the line of reflection is x= 1.

Now, apply the rule of translation to the black triangle, and we get;

A(2, 8)→(2, 8-7)=A'(2, 1)

B(2, 5)→(2, 5-7)=B'(2, -2)

C(6, 5)→(6, 5-7)=C'(6, -2)

Now, apply the rule of reflection over the line x =1.

That is, (x, y)→(-x+2, y)

A'(2, 1)→(-2+2, 1)=A''(0, 1)

B'(2, -2)→(-2+2, -2)=B''(0, -2)

C'(6, -2)→(-6+2, -2)=C''(-4, -2)

You can see the graph of the Glide reflection as shown below.

Therefore, option D is the correct answer.

Kevin measured a line to be 12.4 inches long. If the actual length of the line is 15.7 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?

Answers

Answer:

The percent error of the measurement, to the nearest tenth of a percent is [tex]21.0\%[/tex]

Step-by-step explanation:

Estimated length of a line = 12.4 inches

Actual length of the line = 15.7 inches

Error = 15.7 - 12.4 = 3.3 inches

Percent error of the measurement [tex]=\frac{3.3}{15.7}(100)=21.02[/tex] ≈ 21.0

So, the percent error of the measurement, to the nearest tenth of a percent is [tex]21.0\%[/tex]

Which of the following are point slope form of the line going through (-4,6) and (1,2)

Answers

Answer:

answer in comment

Step-by-step explanation:

So, we have to find the slope of the line. We are given two points, so we can use those:

(x1,y1) = (-4,6)

(x2,y2) = (1,2)

m = (y2-y1)/(x2-x1) = (2-6)/(1--4) = (2-6)/(1+4) = -4/5

Also, we know that point-slope is of the form:

(y-y1) = m*(x-x1)

It doesn't matter which point you use, though, you can also use:

(y-y2) = m*(x-x2)

So we can plug the variables into the equation and get:

(y-2) = -4/5*(x-1)

OR

(y-6) = -4/5*(x+4)

Hi there! The answer for this question would be 9!

Explanation:

0.09 is also 9 since 1.00 is 1 whole in fraction form. This means that 0.09 is also 9/100 in fraction form.

Final Result: 9

Answer: 9

Step-by-step explanation:

On both sides of the equation, there is the 27/100. So we can essentially ignore that because the other two terms just have to be equal. The 0.09 has a 9 in the hundredths place. So that means the decimal is equivalent to 9/100
