geometry solving for x in triangles

Answer:

D

Step-by-step explanation:

First of all, i mean A and B are out first thing because you don't have enough information to find out if it's true.

C is incorrect because as stated before, not enough information.

However,

You know that the angles 1-8 are all supplementary, which means that 1 and 2 can be added to make 180 degrees, as so can 3 and 4, 3 and 1. 2 and 4, blah blah blah.

In D, the angles that are being added are supplementary, because the three lines making up that weird figure is adjacent and is parallel to each other.

If you give one of the angles a degree, you know that 180-x with x being that degree, will equal the other angle on the other side of the lines.

Therefore its D.

Edit:

I just realized that theres an angle stated at the top of the screen. Still with that angle given, A and B is incorrect and the answer is still D.

Answer:

y=8

Step-by-step explanation:

The two triangles are similar, but scaled to a ratio.

Given the ratio of two corresponding sides AC and NL, the scale is 10:5 which is 2. So, the side MN when scaled to the same ratio, the corresponding side's length y = 4*2 = 8 ft

Answer:(8,65)

Because if you were to write this as an equation it would be 25+5x=y than you plug in each variables until determined true.

Answer:

x = 14

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

Step-by-step explanation:

1). [tex]8\frac{1}{4}[/tex] ÷ [tex]\frac{3}{4}[/tex]

= [tex]\frac{33}{4}[/tex] ÷ [tex]\frac{3}{4}[/tex]

= [tex]\frac{33}{4}\times \frac{4}{3}[/tex]

= 11

2). [tex]3\frac{1}{3}[/tex] ÷ [tex]\frac{10}{3}[/tex]

= [tex]\frac{10}{3}[/tex] ÷ [tex]\frac{10}{3}[/tex]

= [tex]\frac{10}{3}\times \frac{3}{10}[/tex]

= 1

3). [tex]\frac{5}{4}[/tex] ÷ [tex]\frac{1}{4}[/tex]

= [tex]\frac{5}{4}\times \frac{4}{1}[/tex]

= 5

4). [tex]\frac{25}{4}[/tex] ÷ [tex]6\frac{1}{4}[/tex]

= [tex]\frac{25}{4}[/tex] ÷ [tex]\frac{25}{4}[/tex]

= [tex]\frac{25}{4}\times \frac{4}{25}[/tex]

= 1

5). [tex]11\frac{1}{4}[/tex] ÷ [tex]\frac{9}{4}[/tex]

= [tex]\frac{45}{4}[/tex] ÷ [tex]\frac{9}{4}[/tex]

= [tex]\frac{45}{4}\times \frac{4}{9}[/tex]

= 5

6). [tex]3\frac{1}{7}[/tex] ÷ [tex]\frac{2}{7}[/tex]

= [tex]\frac{22}{7}[/tex] ÷ [tex]\frac{2}{7}[/tex]

= [tex]\frac{22}{7}\times \frac{7}{2}[/tex]

= 11

Now we can classify the expressions by their quotients as 1, 5 and 11.

Answer: Celsius

Step-by-step explanation: Scale based on 0° for the freezing point of water and 100° for the boiling point of water.

Answer:

r(180°,0) is a rotation of 180° degrees over the origin.

Notice that this rotation moves our figure to the opposite quadrant (so a translation of two quadrants).

Then this is equivalent to:

A reflection over the x-axis followed by a reflection over the y-axis.

Or.

A reflection over the y-axis followed by a reflection over the x-axis.

There is another possible reflection, but it depends on where is our figure.

If the figure is in the first or third quadrant, a reflection over the line y = -x is equivalent to the rotation.

If the figure is in the second or third quadrant, then the reflection over the line y = x is equivalent to the rotation.

We can combine those two and write:

A reflection over the line y = (-1)^n*x.

Where n is the number associated with the quadrant where the figure is in.

Answer:

8.2

Step-by-step explanation:

3.2+2.3+2.7=8.2

Given:

Butterfly can travels = 82 km each day.

Total distance = 3936 km.

To find:

The number of day it takes to travel the given distance.

Solution:

Let the number of days it takes to travel be d.

Butterfly can travels about 82 km each day.

So, distance traveled by it in d days = (82d) km

Total distance is about 3936 km.

[tex]82d=3936[/tex]

To isolate d , we need to divide both sides by 82.

[tex]\dfrac{82d}{82}=\dfrac{3936}{82}[/tex]

[tex]d=48[/tex]

Therefore, the required number of days is 48.

Answer:

x = 66/7 & area = 132/7

Step-by-step explanation:

7x-9=0

x=9/7

substitute value of x in 5x-3;

5(9/7)+3=66/7

Then, a*a,

thus, 2(66/7) = 132/7

Step-by-step explanation:

If Grayson begins saving $1,000 per month and makes 9% a year, compounded monthly, he will have $667,887 in retirement. Therefore, $667,887 is the correct number.

A financial notion known as future value (FV) gives a worth to an asset based on anticipated factors like future interest rates and cashflows. Knowing how much their money might be in five years, given an anticipated rate of return, may be helpful for an investor. Future value is the idea of taking the investment's current worth, adding anticipated development, and estimating what the investment is going to cost in the future.

To calculate the amount of money Grayson will have at retirement, we can use the formula for the future value of an annuity:

FV = Pmt x (((1 + r/n)^(n*t)) - 1) / (r/n)

where:

FV is the future value of the annuity (i.e., the amount Grayson will have at retirement)

Pmt is the monthly payment ($1,000 in this case)

r is the annual interest rate (9% in this case)

The number of annual increasing times is n. (12 for monthly compounding)

t is the number of years (20 in this case)

Plugging in the numbers, we get:

FV = 1000 x (((1 + 0.09/12)⁽¹²*²⁰⁾) - 1) / (0.09/12)

FV = $667,887.20

Therefore, Grayson will have $667,887 at retirement if he starts saving $1,000 per month and earns 9% a year, compounded monthly. Therefore, the answer is $667,887.
