the angle measures of a triangle are in the ratio 5:6:7. find the angle measures of the triangle

Answers

Answer:

50°, 60°, 70°

Step-by-step explanation:

Sum the parts of the ratio, 5 + 6 + 7 = 18 parts

The 3 angles in a triangle sum to 180° , then

180° ÷ 18 = 10° ← value of 1 part of the ratio, then

5 parts = 5 × 10° = 50°

6 parts = 6 × 10° = 60°

7 parts = 7 × 10° = 70°

The angle measures of the triangle are 50° , 60° , 70°

The accompanying graph is a sketch of the function
y = f(x) over the interval 0 SXS 7.
What is the value of (f. f)(6)?
1) 1 2) 2 3) (4) -2

Answers

A composite function combines two or more functions to generate a new function.

The value of [tex]\mathbf{f(f(6))}[/tex] is -2

The require parameter is:

[tex]\mathbf{f(f(6))}[/tex]

First, we calculate f(6)

From the graph (see attachment)

[tex]\mathbf{f(6) = 2}[/tex]

So, the function [tex]\mathbf{f(f(6))}[/tex] becomes:

[tex]\mathbf{f(2)}[/tex]

In other words,

[tex]\mathbf{f(f(6)) = f(2)}[/tex]

Next, we calculate f(2)

From the graph

[tex]\mathbf{f(2) = -2}[/tex]

So:

[tex]\mathbf{f(f(6)) = -2}[/tex]

Hence, the value of [tex]\mathbf{f(f(6))}[/tex] is -2

Liam knows the key to making creamy risotto, a rice dish, is to add the liquid to the rice gradually. He adds 5 ladles of chicken broth to his rice before adding seasoning, and he continues to add 2 ladles of broth each minute afterwards.Write an equation that shows the relationship between the number of minutes since Liam added the seasoning, x, and the total number of ladles of broth he has added, y.

Answers

The equation that shows the relationship between the number of minutes and total number of ladles of broth is y = 2x + 5

Let x represent the number of minutes and y represent the total number of ladies.

Since he adds 2 ladles of broth each minute and he has 5 ladies initially, hence:

y = 2x + 5

The equation that shows the relationship between the number of minutes and total number of ladles of broth is y = 2x + 5

find the value of each variable 2x+4x+108

Answers

Answer:

Step-by-step explanation:

2x + 4x + 180

We have to do combine like terms.

2x and 4x are like terms, so add 2x to 4x. Which gives you 6x. Now you have the expres 6x + 180. You can’t find the variable for this expression, its unsolvable. If you meant, “2x + 4x = 180” Then yes, it would be solvable.

All you would have to do Is, 2x + 4x which gives you 6x, and now divide both side by 6. 6x divided by 6, the two 6 would cancel out, and 180 divide by 6, leaving you with 30. So x should equal to 30.

Harper knows he is 50 yards from school. The map on his phone shows that the school is 34 inch from his current location.
How far is Harper from home, if the map shows the distance as 3 inches?

Answers

Answer:

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

1. We know that 1 yard is 36 inches, therefore, 50 yards expressed in inches is:

(50)(36)=1800in

2. If he is 50 yards from school and the map shows that the school is 34 inches from his current location, when it shows 3 inches the real distance is:

(1800)(3in)/24in=158.82

3. If you can to express it in yards:

158.82/36=4.41yd

Therefore, the answer is: 158.82 inches or 4.41 yards.

Sadie is doing weekly payroll for her employees at her car dealership. Her employees make a base salary plus commission. The function LaTeX: E(x)=\mid 5- \frac{6x}{2}\mid models the way Sadie calculates the commission where x represents the number of cars the employee sells. If one of her employees sells 7 cars, how much commission will they make?

Answers

The commission function is an illustration of the absolute functions

The commission for the sales of 7 cars is 16

The function is given as:

[tex]\mathbf{E(x)=\mid 5- \frac{6x}{2}\mid}[/tex]

When an employee sells 7 cars, we have:

x = 7

So, the equation becomes

[tex]\mathbf{E(x)=\mid 5- \frac{6\times 7}{2}\mid}[/tex]

Simplify

[tex]\mathbf{E(x)=\mid 5- 3\times 7\mid}[/tex]

[tex]\mathbf{E(x)=\mid 5- 21\mid}[/tex]

Simplify

[tex]\mathbf{E(x)=\mid- 16\mid}[/tex]

Remove absolute brackets

[tex]\mathbf{E(x) = 16}[/tex]

Hence, the commission for the sales of 7 cars is 16
