5 0

Answer:

b = 7.9

Step-by-step explanation:

A = 37       a =

B = 53       b =

C = 90       c = 10

B = 180 - 90 -37 = 53

\frac{sinB}{b} = \frac{sinC}{c}\\ \frac{sin(53)}{b} = \frac{sin(90)}{10}\\ b = \frac{10 sin(53)}{sin(90)} \\b = 7.9

Help please (●´⌓`●) ​
Triss [41]

Answer: 39ft^2

Step-by-step explanation:

This is a rectangle missing a piece which looks like a triangle.

Find the area of the rectangle and subtract the area of the triangle.

Rectangle:

A=l*w\\A=(9ft)(5ft)\\A=45ft^2

Triangle:

A=\frac{hb}{2}\\ A=\frac{(3ft)(4ft)}{2}\\ A= \frac{12ft^2}{2}\\ A=6ft^2

Now subtract the area of the triangle from the area of the rectangle.

45ft^2-6ft^2=39ft^2

xenn [34]

Answer:

12

Step-by-step explanation:

The highest common factor between 24 and 36 is 12.

24: 2 * 2 * 2 * 3

36: 2 * 2 * 3 * 3

They both have two 2s and one 3.

in each of the 12 bags, you would put 2 Candles and 3 bottles of lotion. Doesn't look right, but it is.

Find an equation in standard form for the hyperbola with vertices at (0, ±2) and foci at (0, ±7).
Alisiya [41]
<span>Standard Form of an Equation of an Hyperbola opening up and down is:

(y-k)^2 / b^2 - (x-h)^2 / a^2 = 1

</span><span>where Pt(h,k) is a center with vertices 'b' units up and down from center.

</span><span>vertices: vertices: (0,+-2) b = 2 AND Center is (0,-0)

(y)^2/4-(x)^2/a^2=1

</span><span>foci: (0,+-7) 

a^2 = 24 

square root of 4 + a^2 = 5.29

4 + 5.29 = 9.29

y^2 / 4 - x^2 / 24 = 1</span>
