Answer:

Find the value of x in each of the given figures.

Step by step explanation :

a. .. Let the triangle be ABC

we have to find the value of A

ATTQ ( According to the question) we have ::

B = 25°

C = 105° + ___ = 180° ( adjacent angles)

C = 75 ° = 180° - 105° ( transfer 105° from LHS to RHS)

The sum of all interior angles of a triangle is 180° .

so, A+B+C = 180°

A+ 25° + 75° = 180°

A+ 100° = 180°

A= 180° - 100°

A = 80°

therefore answer is 80°

b. .. Let the triangle be ABC.

we have to find the value of x

ATTQ , we have

A= 3x+2°

B=2x°

C = 152° + ___ = 180°

C= 180°- 152° = 28°

The sum of all interior angles of triangle is 180°

so, A+B+C = 180°

3x+2° + 2x° + 28° = 180°

first add the variables then numbers

5x° + 30° = 180°

5x° = 180° - 30°

5x ° = 150°

x° = 150° / 5

x = 30°

therefore answer is 30°

thank you so much..

An athlete runs an equal distance 2 days a week. The other 5 days of the week, he runs a total of 11 miles. Write an equation

katovenus [111]

Ok since the athlete an equal distance of 2 days a week and he runs a total of 11 miles in 5 days you will need to think back so before he had 11 miles done next weak he had a total of 19 miles so you will start at 11 then count up to 19.

Use a number line to show how many days it took for the athlete to get 19 miles.

Then once you do the number line count the lumps and that’s how many days it took for the athlete to get 19 miles.

Hope this helped.

1. On the last 5 quizzes, Marco has earned a total of 21 out of 25 possible points. If he has a perfect

Nonamiya [84]

The number of points Marco needs to bring his average up to 90% is 15points.

If there's a possible 25 possible points, and Marco has taken 5 quizzes;

Evidently, each quiz has weighs 5 points.

Mathematically;

$\frac{21 + 5x}{5(5 + x)} \times 100\% = \frac{90}{100}$

2100 + 500x = 2250 + 450x

50x = 150

x = 3.

Therefore, he needs 5x points = 15 points to bring his average up to 90%.

A real estate office manages an apartment complex with 50 units. When the rent is $780 per month, all 50 units are occupied. How

Nataliya [291]

Answer:

A) The linear equation is $x=\frac{-1}{15}p+102$

B) When the rent is raised to $855 the number of units occupied is 45.

C) When the rent is lowered to $795 the number of units occupied is 49.

Step-by-step explanation:

A) A linear equation for the demand is written as $x=mp+p_{0}$ , where $m$ is the slope, $x$ is the number of occupied units, $p$ is the rent.

$m$ is calculated using the problem information. When the rent is $p=$780$ then $x=50$ and when the rent is $p=$825$ then $x=47$ .

Using the slope equation we have:

$m=\frac{50-47}{780-825}=\frac{-3}{45}=\frac{-1}{15}$

Thus the linear equation is:

$x=\frac{-1}{15}p+p_{0}$

In order to calculate $p_{0}$ we use the problem information, When the rent is $p=$780$ then number of occupied units is $x=50$ , thus:

$50=\frac{-1}{15}780+p_{0} \\\\50=-52+p_{0} \\\\p_{0}=102 \\$

Finally, the linear equation is:

$x=\frac{-1}{15}p+102$

B) The demand equation is plot in the attached file, the number of units occupied when the rent is raised to $855 is 45.

C) In order to predict the number of occupied units lets use the equation:

$x=\frac{-1}{15}p+102$

where $p=$795$ , then:

$x=\frac{-1}{15}795+102\\ \\x=-53+102\\\\x=49$

Thus, when the rent is lowered to $795 the number of units occupied is 49.

Find the component form of the resultant vector

Lera25 [3.4K]

Answer to problem 1 is {-144,-192}
Answer to problem 2 is {-12,-12}

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

Explanation:

Vector u is given to be u = {-18,-24}
To compute the vector 8*u, we multiply both sides by 8 and multiply each coordinate by 8
The rule I'm using is if u = (a,b) then k*u = (k*a,k*b)

So,
u = {-18,-24}
8*u = 8*{-18,-24}
8*u = {8*(-18),8*(-24)}
8*u = {-144,-192}

Problem 2 is handled the same way
f = {-2,-2}
6*f = 6*{-2,-2}
6*f = {6*(-2),6*(-2)}
6*f = {-12,-12}
