Answer:

1: 12.96

2: 32.25

3: 169

4: 77mi

5: 65

Step-by-step explanation:

1:a^2+b^2=c^2 -> 17^2-11^2=a^2 ->sqrt of 168=a=12.96

2: 16^2+28^2=c^2 -> \sqrt{1040} =c=32.25

3:5^2+12^2=13^2 -> 169=169

4: you can form a triangle with this problem: 44mi=b and 63mi=a so you need to find c

mina [271]

Answer:

-10 points

Step-by-step explanation:

A game show awards 30 points for each correct answer and deducts 50 points for each in correct answer. A contestant answers 2 questions incorrectly and 3 questions correctly. What is his final score?

Let us say Initial number of points = 0

Hence,

He answers 2 incorrectly = 0 - 50 - 50

= -100

He answers 3 correctly =-100 + 30 + 30 + 30

His final score = -100 + 30 + 30 + 30

= -10 points

Which side in the smallest triangle would correspond with HI in the largest triangle?

tensa zangetsu [6.8K]

The side of the small triangle that will correspond to the side of HI is side IK.

<h3>How to find corresponding side of similar triangles?</h3>

Similar triangles are triangles that have the same shape but different size.

In similar triangles, corresponding sides are always in the same ratio.

The corresponding angles are equal.

Therefore, the side of the small triangle that will correspond to the side of HI is side IK.

Write the standard form of the equation of the line through the given points.

fenix001 [56]

You first have to find the slope using the slope formula. That looks like this with our values: $\frac{-2-(-1)}{5-(-3)}=- \frac{1}{8}$ . So the slope is -1/8. Use one of the points to first write the equation in y = mx + b form. We have an x and a y to use from one of the points and we also have the slope we just found. Filling in accordingly to solve for b gives us $-2=5(- \frac{1}{8})+b$ and $-2=- \frac{5}{8}+b$ . Adding 5/8 to both sides and getting a common denominator gives us that $b=- \frac{11}{8}$ . Writing our slope-intercept form we have $y=- \frac{1}{8}x- \frac{11}{8}$ . Standard form for a line is Ax + By = C...no fractions allowed. So let's get rid of that 8 by multiplying each term by 8 to get 8y = -x - 11. Add x to both sides to get it into the correct form: x + 8y = -11

St lies on the coordinate plane with s located at (3.2). The midpoint of dt is z(3,9) state the location of the endpoint T thank

77julia77 [94]

Answer:

T = (3,16)

Step-by-step explanation:

The midpoint formula is just another version of the pythagorean theorem, and it states that the midpoint between (x1,y1) and (x2,y2) is $\left(\frac{x_1+x_2}{2}\right),\:\left(\frac{y_1+y_2}{2}\right)$

Substituting what we know:

endpoint S is (3,2) and endpoint T is (x2,y2)

Midpoint Z is (3,9). We will apply the formula -- backwards.

$\left(\frac{3+x_2}{2}\right)=3$ , solving with algebra we get x2 = 3

So the x-coordinate of endpoint T is 3.

$\left(\frac{2+y_2}{2}\right)=9\quad$ , solving with algebra, we get y2 = 16.

So the y-coordinate of endpoint T is 16.

So the location of endpoint T is (3,16)
