Answer:

-100

Step-by-step explanation:

(-13-8)2^2

-25*4=-100

Step-by-step explanation:

First we need to remember the rule of PEMDAS and then simplify.

5×10/5+2=12

Multiply

50/5+2=12

Divide

10+2=12

Add

12=12

Answer:12.59

Step-by-step explanation:

From the diagram you can see that we have constructed a right triangle, with height A and base 15.

Length of shadow = 15 feet.

Height of flagpole = A.

We know the angle of elevation is

40

∘

. Using this angle and the tangent ratio, we can find A.

Answer:

Your answer is 50 (or b)

Step-by-step explanation:

You can tell this because the inside angle is 25 but the cornner says 2x so you have to double it so 25+25=50...hope this helps

:P

Answer:

50

Step-by-step explanation:

There is a straight line at the bottom which is 180 degrees. On the right side the angle measure is 150 degrees so you subtract that by 180 and you get 30 degrees making it supplementary. Next you should know that there is 180 degrees in a triangle. Now you formulate the equation 30+50+2x =180. Then you solve for x and you get the solution x=50 which is your answer. Now you can substitute 50 in for x and see if all the angle measures add up to 180 degrees.

If you can please make my answer the brainliest that would be much appreciated. Thanks!

Answer:

no, 3/15 reduces to 1/3 and 1:3 isn't equal to 1:5

Answer:

36.4%

Step-by-step explanation:

Actual wait time is 55 minutes

Approximate wait time is 35 minutes

Therefore the percent error can be calculated as follows

= 35-55/55 × 100

= 20/55 × 100

= 0.3636 × 100

= 36.4%

Answer: I think 4

Step-by-step explanation:

Answer:

No matter what scale factor is dilated, the angles will not change.

My explanation:

A 30-60-90 right triangle (literally pronounced "thirty sixty ninety") is a special type of right triangle where the three angles measure 30 degrees, 60 degrees, and 90 degrees. The triangle is significant because the sides exist in an easy-to-remember ratio: 1:√3:2.

That is to say, the hypotenuse is twice as long as the shorter leg, and the longer leg is the square root of 3 times the shorter leg. You might also remember it as "X, 2X, and X roots of 3", which is how I remember it, but then you have to remember that 2X is actually the longest side, not X roots of 3.

Which side is which? The side opposite the 30 degree angle will have the shortest length. The side opposite the 60 degree angle will be √3

times as long, and the side opposite the 90 degree angle will be twice as long. The triangle below diagrams this relationship. Remember that the longest side will be opposite the largest angle, and the shortest opposite the smallest angle.

Hopefully this helped, if not HMU and I will try to get you a better answer! :)

Answer:

Distance between Lisa and the tree in the water = 26.5 ft

Step-by-step explanation:

From the figure attached,

Lisa is a point L, Molly is at M and a tree stick at point S.

By applying sine rule in ΔLMS,

[tex]\frac{\text{SinL}}{\text{SM}}=\frac{\text{SinM}}{LS}=\frac{\text{SinS}}{\text{LM}}[/tex]

[tex]\frac{\text{Sin(54)}}{22}=\frac{\text{Sin(103)}}{\text{LS}}[/tex]

LS = [tex]\frac{22\times \text{Sin}(103)}{\text{Sin(54)}}[/tex]

LS = 26.5 ft

Therefore, distance between Lisa and the tree in the water is 26.5 ft.

Answer: Coordinates of the image are (-2 , -1)

Step-by-step explanation:

The rule for 180° rotation counterclockwise is:

(x , y) ⇒ (-x , -y)

This means that to get the coordinates of a point rotated 180° counterclockwise, all you have to do is flip the signs of both the x and the y

Now, we are given the point (-4 , 1)

Applying the above rule:

[tex]( x image, y image) = (-(-4),-(1))[/tex]

[tex](x image, y image) =(-2, -1)[/tex]

Answer:

40.04

Step-by-step explanation:

It was at 40.04 before the 23% increase. To find 23 % of 52 set it up as a inequality.

x/52 = 23/100

Cross multiply

52 * 23 =  1,196    100 * x =100x

Now solve for x.

100x /100 = 1,196/100          x = 11.96

Subtract answer from 52 to get answer

52 - 11.96 = 40.04

Answer:

(0, 0), (4, 0), (4, -5)

Step-by-step explanation:

This one keeps the same lengths of the previous triangle. It also keeps the same proportions (or something) etc, etc. I solved this problem by graphing and seeing which one fit best.

Answer:(x + 12) ^2 -60

Answer:

ANSWER

Step-by-step explanation:

In the table, look at the x values. Now, in the function ( the expression in the question) substitute the x values from the table into the function. The first column would be 4x1-1sqaured so 4 x 1 = 4    1 squared is 1   so 4 - 1 is 3. So the answer for the first box is 3.
