What is the perimeter?

Answers

Answer: 24

8 + 6 = 14

to find the other missing measure (slanted side) use pythagorean theorem

c^2 = a^2 + b^2

c^2 = 6^2 + 8^2

c^2 = 36 + 64

c^2 = 100

c = 10

then add all the measurements since it’s perimeter

10 + 6 + 8 = 24

Answer:

P=22

Step-by-step explanation:

b=8

h=6

the slanted side=8

8+8+6=22

Answer:

The answer is 420.

Step-by-step explanation:

Because since we know it wants 140 grams of fish. And twice as many pasta than fish. You can simply just do this: 140 x 2 = 280. So 140 + 280 will = 420. There you go!

420 grams
Do 140 x 2 to get the pasta (double the fish) to get 280. Then add the grams of fish back 280 + 140 which equals 420 grams

12. Tiger Woods was 4 under par (-4) in the first round. He shot 2 over par (+2) in the second round. He shot the same score in the 3rd and 4th rounds. He finished at 8 under par ( -8). What did he shoot in the 3rd and 4th rounds?

Answers

I think -3; If the final par was -8, you would subtract (-4 + 2), you would get -6. Then you just divide it in half because it said he scored the same in rounds 3 and 4, leaving you with -3.

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{PQ}{16}[/tex] = [tex]\frac{30}{12}[/tex] ( cross- multiply )

12 PQ = 480 ( divide both sides by 12 )

PQ = 40 in

Darnell is trying to understand the Pythagorean Theorem by drawing a few triangles. He found that 1² + 1² = (√2)² is accurate. Which statement is true about Darnell’s triangle?

A. The triangle is not a right triangle because the lengths of its sides measure the same.

B. The triangle is not a right triangle because the hypotenuse is shorter that the lengths of its sides.

C. The triangle is a right triangle, the lengths of its sides are 1 and √2 with a hypotenuse of 1.

D. The triangle is a right triangle, the lengths of its sides are 1 and 1 with a hypotenuse of √2.

PLEASE HELP ASAP!!!!

Answers

Answer:

D. The triangle is a right triangle, the lengths of its sides are 1 and 1 with a hypotenuse of √2.

Step-by-step explanation:

The Pythagorean Theorem is modeled by a² + b² = c².

c represents the hypotenuse and a and b represent the other two sides.

The Pythagorean Theorem can only be applied to right triangles.

Given cosθ = .876 and tanθ = -4.731 determine sinθ

Answers

The answer must be -0.185

Answer:

[tex]sin\theta[/tex]= -4.144356

Step-by-step explanation:

[tex]tan\theta=\frac{sin\theta}{cos\theta}[/tex]

Therefore:

[tex]sin\theta = tan\theta.cos\theta[/tex]

[tex]sin\theta[/tex] = -4.731 × 0.876

[tex]sin\theta[/tex] = -4.144356

Jeff drew a line through (0, 0) and (7, 7) and said it was the line of best fit for the data.

Part A: Explain why Jeff's line is NOT the best fit.
Part B: What would be a better line of best fit for the scatter plot?
Part C: How does the actual line of best fit compare with Jeff's line?

Answers

Answer:

The line of best fit would not be right because there would be a big gap of space. The line should be the cooardinate 7,3 as this covers the line and the cooardinate 7,7 is an outlier. The new line is more accurately placed

Step-by-step explanation:

Answer:

The actual line of best fit would be from (0, 0) to (7, 4), this is because it covers majority of the points. All the other points are just anomalies. Moreover, Jeff's line is NOT the line of best fit because it is not accurate and is out of place. Furthermore, the actualy line of best fit is 3 places lower on the y-axis then Jeff's line of best fit.
