60x + 75 :))

Explanation: were disrupting 15 to 4 & 5 so were multiplying because when a number is in parenthesis like this a(b) we multiply.

Answer:

60x + 75

Step-by-step explanation:

When using distributive property, multiply the number on the outside of the parenthesis by the numbers on the inside of the parenthesis.

Here, the number outside of the parenthesis is 15.

15 (4x + 5)

15 ⋅ 4x = 60x

15 ⋅ 5 = 75

KEEP WHICHEVER SIGN IS IN THE MIDDLE OF THE PARENTHESIS.

15 (4x + 5) = 60x + 75

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

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.

Answer:

40 and 202.5 m³

Step-by-step explanation:

(7)

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

-------------------------------------------------------------------

The volume (V) of a pyramid is calculated as

V = [tex]\frac{1}{3}[/tex] Ah ( A is the area of the base and h the height ) , then

V = [tex]\frac{1}{3}[/tex] × 9² × 7.5

= [tex]\frac{1}{3}[/tex] × 81 × 7.5

= 27 × 7.5

= 202.5 m³

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
