Answer:

Step-by-step explanation:

Look at the LHS: you have the square of x, then you have 2 times x, times -1. to complete a square you just need to add the square of -1, that is 1. That becomes

$x^2-2x +1 = (x-1)^2$

A canoe requires 8 hours of fabrication and a rowboat 5 hours. The fabrication departments has at most 107 hours of labor availa

Elina [12.6K]

Answer: A

Step-by-step explanation: Canoe → 8h →X

Rowboat → 5h → Y

Fabrication department has at most 107, which means it need to be less than 107 hours.

This way, the amount of time to fabricate X canoes = 8X plus the amount of time to fabricate Y Rowboat = 5Y must be less than 107.

8X + 5Y < 107

DanielleElmas [232]

Answer:

4 3/8 miles

Step-by-step explanation:

We are told that: the scale on a map is 1 inch =2 1/2 miles.the distance between two streets on the map is 1 3/4 inches

If 1 inches = 2 1/2 miles

1 3/4 inches =

Cross Multiply

1 3/4 × 2 1/2/1

= 7/4 × 5/2

= 35/8

= 4 3/8 miles

The actual distance between these streets is 4 3/8 miles

Find the measure of C to the nearest degree.

Alisiya [41]

Let the ∠C be : θ

From the figure, We can see that the Side which is opposite to angle θ is measuring 7 units

Also, We can notice that Hypotenuse is 11 units

As we are dealing with opposite and hypotenuse, we can clearly use Sinθ to find out the angle θ

We know that :

$\bigstar \ \ \boxed{\sf{Sin\theta = \dfrac{Opposite \ Side}{Hypotenuse}}}$

$\implies \sf{Sin\theta = \dfrac{7}{11}}$

$\implies \sf{\theta = Sin^{-1}\bigg(\dfrac{7}{11}\bigg)}$

$\implies \sf{\theta = 39.52^{\circ}}$

Answer : The measure of ∠C to the nearest degree is 38°
