I had a question on a test that just like that one and I got it right

Answer:

50⁰

Step-by-step explanation:

we know that sum of angles in a triangle is equal to 180⁰

on adding the angles we get

x⁰+x⁰+20⁰+x⁰+70⁰=180⁰

3x⁰+90⁰=180⁰

3x⁰=90⁰

x⁰=30⁰

Now angle R=x+20=30+20=50⁰

Answer is 50⁰

Answer:

4). 3

5). 600

Step-by-step explanation:

formula of finding intrest earned is (p×r×t)/100

by putting this formulae____

( HERE p means principal , r means rate , t means time )

(p×r×t) /100= interest

(480×r×5) / 100=100.80

(336×r) / 100 = 100.80

336×r= 100.80×100

r= (100.80×100)/336

r=3

5). (p×r×t)/100=interest

(p×4×5) /100 = 120.00

p×4×5 = 120.00×100

p= 12000 / 4×5

P=12000/20

P=600

Answer:

[tex]y = \frac{11}{13} x + 2 \frac{10}{13} [/tex]

Step-by-step explanation:

y= mx +c, where m is the slope and c is the y-intercept.

We need to find the value of m and c, which can be done by using the slope formula and by substituting a pair of coordinates respectively. Find m first before finding the value of c.

[tex]\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]

[tex]slope = \frac{7 - ( - 4)}{5 - ( - 8)} [/tex]

[tex]slope = \frac{7 + 4}{5 + 8} [/tex]

[tex]slope = \frac{11}{13} [/tex]

Substitute the value of m into the equation:

[tex]y = \frac{11}{13} x + c[/tex]

Substitute a pair of coordinates:

When x= 5, y= 7,

[tex]7 = \frac{11}{13} (5) + c[/tex]

[tex]c = 7 - \frac{55}{13} [/tex]

[tex]c = \frac{91}{13} - \frac{55}{13} [/tex]

[tex]c = \frac{36}{13} [/tex]

[tex]c = 2 \frac{10}{13} [/tex]

Thus, the equation of the line is [tex]y = \frac{11}{13} x + 2 \frac{10}{13} [/tex].

Answer:

x=10

Step-by-step explanation:

so your given an angle, 110, and another with an equation, 8x+30, which happens to be vertical to 110 degree angle meaning they are equal, so they both are equal to 110 now how do you solve for x? you simply reverse the equation that x is in, so you subtract 110-30=80, then divide by 8 giving you 10, so x=10.

Answer:

X = 10, because of the second angle's equation. 8x + 30 hints the solution. 110 - 30 is 80, and 80 / 8x In this case, x can be represented as itself is 10

Answer:

35.355 cm

Step-by-step explanation:

if u imagine the 3D cut triangle but at a different angle, u would imagine the legnth of the parallelogram being 7.071 which is the hypotenuse of the triangle... along with the hypotenuse given, they also gave the side lenght of the parallelogram which is 5cm... 5 x 7.071 = 35.355 cm

Answer

Kevin jumped 1.55 meters

Ben jumped 1.445

micheal jumped 1.201

Step-by-step explanation:

The reason I used those numbers is Kevin jumped the highest, so I made him jump the farthest. Micheal jumped 334 thousandths of a meterless than Kevin so I put he jumped 1.201.

Step-by-step explanation:

its closest to -.9 so it has to be that one

Answer:

Now, △DEF has interior angles with measures y°, 70°, and 20°.

By using angle sum property,

Now, we can say that,

"The two triangles are not similar because x≠y"

As one angle of measure 70 degree is common in both the triangles.

If 'x' would be equal to 'y' , then we could say that the triangles are similar by AA criteria.

Therefore, the two triangles are not similar because x is not equal to

Step-by-step explanation:

Answer:

the triangles are not similar. If they were, they would have the same angles.

The interior angles are not congruent. We can rule out choice B and C.

Just because they have one equal angle does not make them similar. We can rule out D.

A is the best answer.

Answer:

[tex]beinggreat78~here![/tex]

First step to simplifying ratios is to find the ratio. The ratio would be 14:16. The next step is to find the least common factor and simplify by dividing. The least common factor is 2, so divide both numbers by 2.

[tex]\frac{14 / 2}{16 / 2} = \frac{7}{8}~or~7:8[/tex]

With that info, your answer is 7:8

What have we learned?

Answer:

48 cubes

Step-by-step explanation:

To begin, we must find the volume of both the cube and the rectangular prism.

The volume of a cube is a side to the 3rd power.

1/3 · 1/3 · 1/3 = 1/27

The volume of a prism is l * w * h.

2/3 · 1 · 8/3 = 16/9

Now, we have the volume of a cube and the prism. Since we have the find how many cubes can fit into the prism, we must divide 16/9 by 1/27.

16/9 ÷ 1/27 = 16/9 · 27/1 = 432/9 = 48/1 = 48

Therefore, 48 cubes will fit into the prism.

Answer:

-7x - 14

Step-by-step explanation:

By simplifying the expression:

-3(2x+5) - (x - 1)

-6x-15 -x + 1

-7x - 14

Answer:

-7x - 14

Step-by-step explanation:

You can use the distributive property to find an equivalent expression.

Distribute -3 to 2x + 5.

(-3 × 2x) + (-3 × 5) = -6x + (-15) = -6x - 15

Distribute -1 to x - 1. (It is -1 because there is always a 1 in front of things like x = 1x and (x + 1) = 1(x + 1). 1 times anything equals the number it is multiplied by. There is a - sign in front of the parenthesis, which makes the invisible 1 a -1.)

(-1 × x) + (-1 × -1) = -x + 1

You can simplify the expression.

(-6x - 15) + (-x + 1) = -7x - 15 + 1 = -7x - 14

It sounds like the machine produced eight blocks per minute and the other charts aren't showing the consistent flow you're looking for.

Answer:

The black line has the greater slope.

Step-by-step explanation:

One way to think about which line has the greater slope is to imagine (or draw) a car on top of each line driving from left to right. If the car is driving up a steeper hill then the slope is greater.

To show your work though, starting at the y-intercept on the black line, find another point that you can see well on the line such as (3, 4). To get from the y-intercept to (3,4) go up 2 and right 3 so the slope is 2/3.

For the blue line, find a point that is easy to see such as (2, 3). To get from the y-intercept to (2, 3) go up 1 and right 2 so the slope is 1/2.

(Remember slope is y/x or rise/run)

Since 2/3 is bigger than 1/2, the slope of the black line is greater.
