EASY 7TH GRADE MATH QUESTION!!! FIRST PERSON MARKED BRAINLIEST!!! PLEASE ANSWER QUICKLY AND CORRECTLY!!

Answer:

40°, 60° and 80°

Step-by-step explanation:

sum the parts of the ratio, 2 + 3 + 4 = 9 parts

Divide 180° ( sum of angles in a triangle) by 9 to find the value of one part of the ratio.

180° ÷ 9 = 20° ← value of 1 part of the ratio , then

2 parts = 2 × 20° = 40°

3 parts = 3 × 20° = 60°

4 parts = 4 × 20° = 80°

The angles in the triangle are 40°, 60°, 80°

Answer:

The answer is D.

Step-by-step explanation:

For each of these questions, you just have to substitute one of the x values, where the X is in the equation. Then the equation is true is the Y value you solve for is the same as the corresponding  Y value.

Answer:

its B

x^2/680,625 - y^2/3,319,375 = 1

The equation that be used to determine possible locations of the origin of the sound  [tex]\dfrac{ x^2}{680,625} - \dfrac{ y^2}{3,319,375 }= 1[/tex]

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

A pair of listening posts is 4,000 ft apart.

They both pick up a sound, but one listening post records the sound 1.5 seconds after the other listening post.

Assume sound travels at 1,100 ft/s.

The equation would become

[tex]\dfrac{ x^2}{680,625} - \dfrac{ y^2}{3,319,375 }= 1[/tex]

Answer: 8

Step-by-step explanation: on the left chain, there are 5 4’s, so 4 times 5 is 20 Because you know that, subtract it from 60 to only have the W’s values. So 60-20 is 40 and because there is 5 w’s do 40/5 is 8. Therefore, the value of the w’s is 8 and the value of the 4’s is 20

Hello your question is incomplete attached below is the complete question

answer : ALTITUDE , x = 24

Step-by-step explanation:

The type of segment shown in Blue is ALTITUDE segment

This is because

Angle BCD = Angle CEG (opposite angles)

Angle ACD= Angle CFG (opposite  angles)

Angle ADC = Angle BCD= Angle CEG = Angle CFG

It can be seen that the triangles are similar hence

 18/27=16/x

therefore  X  =24

Answer:

false, true . false

Step-by-step explanation:

if u want an explanantion you can ask me :)

Answer: a. True b. True c. False

Explanation:

a. 65+25 =90 complementary angles add up to 90°

b. 65 + b + 25 = 180

90 + b = 180

b = 180 - 90

b = 90

Check-

65 + 25 + 90 = 180

90 + 90 = 180

180 = 180 ✅

c.not vertical angles because they aren’t across from eachother

Answer:

4

Step-by-step explanation:

To find the side length of the original triangle:

24/3=8 (because it is an equilateral triangle).

Because the triangle is dilated by a factor of 0.5 and the triangle is equilateral, the side lengths of the new triangle is

8*0.5=4

Answer:

the function is f(x) = 7/4x - 2

therefore the average rate of change is 7/4

Answer:

The equation is;

p + 90 = 120 minutes

Danielle’s drive from work to the park took 30 minutes ( p = 30 minutes)

Step-by-step explanation:

Here, we want to write and solve an equation

Here, we want to get the time taken by Daniele from the park to work

From the question, the total commute is two hours

since 1 hour is 60 minutes, it follows that 2 hours is 120 minutes

Now, if we added the time taken to commute both journeys, we have the total as 2 hours

This means;

p + 90 = 120 minutes

p = 120 - 90

p = 30 minutes
