Step-by-step explanation:

So the social studies test she scored higher

Answer:

B

Step-by-step explanation:

You have given angle x and the hypotenuse you are asked to find the adjacent side of the triangle so you would be using

Cosθ = Adjacent/hypotenuse.

cos49 = adjacent/4

1.32 = adjacent/4

2.62 = adjacent

VX = 2.6

Remember!

SOH

Sinθ = opposite/hypotenuse

CAH

Cosθ = adjacent/hypotenuse

TOA

Tanθ = opposite/adjacent

Answer:

y = x + 6

Step-by-step explanation:

y = mx + b

Since (0,6) is your y-intercept (or just positive 6), you have your b part of the equation solved.

The line goes up at a continuous rate of up 1, over 1, so they cancel each other out, making the m part of your equation 1.

So, you have y = 1x + 6 and you change it to just y = x + 6 (since x itself automatically has a 1 before it, when it's by itself).

Hope this helps!

Answer:

2 × 10⁵

Step-by-step explanation:

The following data were obtained from the question:

6×10⁹/ 3×10⁴ =?

The above expression can be simplified as follow:

6×10⁹/ 3×10⁴ = 6×10⁹ ÷ 3×10⁴

Recall:

Aᵐ ÷ Aⁿ = Aᵐ ¯ ⁿ

Therefore,

6×10⁹ ÷ 3×10⁴ = (6/3) × 10⁹ ¯ ⁴

6×10⁹ ÷ 3×10⁴ = 2 × 10⁵

Thus, 6×10⁹/ 3×10⁴ is equal to 2 × 10⁵

Positive Correlation

Step-by-step explanation:

The graph shown as a positive correlation.

Two variables move in the same direction in a positive correlation.

You can also tell that the graph has a correlation that is positive because of the line moving in a upward direction from left to right.

Hope this helps.

Answer:

M= 83/66

Step-by-step explanation:

The formula to solve the slope is y2-y1/x2-x1 so ,

-10-73= -83

7-73= -66

-83/-66= 83/66

Answer:

40 : 320

Step-by-step explanation:

sum the parts of the ratio, 1 + 8 = 9 parts

Divide the quantity by 9 to find the value of one part of the ratio

360 ÷ 9 = 40 ← value of 1 part of the ratio, then

8 parts = 8 × 40 = 320

Then 360 in the ratio 1 : 8 is 40 : 320

Answer:

40:320

Step-by-step explanation:

8+1=9

360/9=40

40 times 1 is 40

40 times 8 is 320

Answer:32 inches

Step-by-step explanation:

Using the pythagorean theorem

40²= 24²+ b²

simplify

1600 = 576 + b²

subtract 576 from both sides

1024 = b²

square root both sides

32= b
