Answer:
Step-by-step explanation:
use pythageran theorem
c=square root of a2+b2
but we are solving angle b
so
b2=c2-a2
b2=225-196
b2=29
b approximately = 5.39 Rounded up
Answer:
5.4
Step-by-step explanation:
c² = a² + b²
15² = 14² + b²
225 = 196 + b²
b² = 225 - 196
b² = 29
b = 5.4

i want to fined out that
a^2+b^2
________is equal to?
a+b
Answer:
(a+b)²-2ab
Step-by-step explanation:
First we need to factorize (a+b)²
(a+b)² = a² + 2ab + b²
(a+b)² = a²+b²+2ab
Subtract 2ab from both sides
(a+b)² - 2ab = a²+b²+2ab - 2ab
(a+b)²-2ab = a²+b²
Swap;
a²+b² = (a+b)²-2ab
Hence the expression of a² + b² is (a+b)²-2ab

A room measures 15 ft by 20 ft by 10 ft. If a basketball has a diameter of 9.6 inches, approximately how many basketballs will be needed to fill the room?
Answer:
10344.827586 basketballs
Step-by-step explanation:
A room measures 15 ft by 20 ft by 10 ft. If a basketball has a diameter of 9.6 inches, approximately how many basketballs will be needed to fill the room?
Step 1
We find the volume of the room
The room is rectangular in shape
Volume = Length × Width × Height
= 15ft × 20ft × 10ft
= 3000ft³
Step 2
Basket ball is spherical in shape
Volume of a sphere = 4/3πr³
Diameter = 9.6 inches
Radius = Diameter/2 = 9.6 /2 = 4.8 inches
Convert Radius from inches to ft
= 4.8inches/12
= 0.408333 feet
Volume of a sphere = 4/3 × π × 0.408333³
= 0.29 ft³
Step 3
3000 ÷ 0.29

Which function represents transforming ƒ(x) = 3x with a reflection over the x-axis and a vertical shift of 4 units?
A) h(x) = 3x + 4
B) h(x) = -3x + 4
C) h(x) = 3x-4
D) h(x) = -3x+4
Answer:
B. h(x) = -3x + 4.
Step-by-step explanation:
I am assuming that the vertical shift is upwards,
A refection in the x axis gives -3x
Vertical shift upwards of 4 gives -3x + 4.

Use a formula to find the amount of wrapping paper you need to wrap a gift in the cylindrical box shown. You need to cover the top, bottom, and all the way around the box. Use 3.14 for .
Answer:
Total wrapping paper need = 960.84 inch²
Step-by-step explanation:
Given:
Height of cylinder box = 8 inch
Radius of cylinder box = 9 inch
Find:
Total wrapping paper need
Computation:
Total wrapping paper need = Total surface area of cylinder
Total surface area of cylinder = 2πr(h + r)
Total wrapping paper need = 2[3.14][9][8+9]
Total wrapping paper need = 2[3.14][9][17]
Total wrapping paper need = [6.28][9][17]
Total wrapping paper need = [56.52][17]
Total wrapping paper need = 960.84 inch²

Find the quotient of 7/8 divided by 1/4 by using the procedure. Write your answer as a proper fraction, whole number or mixed number
Answer:
7/8 x 4/1
make 1/4 a reciprocal (basically just turning the fraction upside down)
then turn the division sign into a multiplication sign and multiply across:
7/8 x 4/1 = 28/8 = 3 4/8 = 3 1/2

Question 1 options:
A 30°-60°-90° triangle has a shorter leg with a length of 14 cm. The hypotenuse of the triangle is ___ cm
From now on, remember that the smallest side in a triangle is always facing the smallest angle of the triangle.
_________________________________
The question told us that the shorter leg has a measure of 14 in which it is tha smallest side of the triangle thus 14 is the facing side to the 30 degrees angle .
As we know, in a right-angled triangle, the facing side to the angle of 30 degrees has half measure of hypotenuse. So :
1/2 × hypotenuse = 14
Multiply both sides by 2
hypotenuse = 28

Arc PR = ___ degrees
===========================================================
Explanation:
Angle PAQ is 90 degrees as the square marker indicates. The adjacent angle RAQ is also 90 degrees.
So overall, central angle PAR is 90+90 = 180 degrees. Arc PQR is 180 degrees which is a semicircle.
If events A and B are independent, P(A) = 0.62, and P(
BA) = 0.93, what is P(B)?
O 0.41
O 0.93
O None of the other answers are correct
O 0.58
O 0.67
Answer:
Step-by-step explanation:
you’re given A=0.62 and B/A=0.93
you’re solving for B
substitute your A value of 0.62
B/0.62=0.93
same as B/0.62=0.93/1
now cross multiply
B= 0.62x0.93
B=0.5766
B=0.58

You mix 3/4 quart of blue paint for every 5/6 quart of yellow paint to make 4 3/4 quarts of green paint. How much blue paint and how much yellow paint do you use?
Answer: We need 2.5 quarts of yellow paint.
Step-by-step explanation:
As per given, The ratio of blue paint to yellow paint is [tex]\frac34: \frac{5}{6}[/tex].
[tex]=3\times6:5\times4\\\\=18:20\\\\ =9:10[/tex]
Total green paint = [tex]4\frac34[/tex] quarts
Quantity of yellow paint required = [tex]\frac{10}{9+10}\times4\frac34[/tex]
[tex]=\frac{10}{19}\times\frac{19}{4}\\=\frac{5}{2}\\=2.5\ $$ quarts$$[/tex]
Hence, We need 2.5 quarts of yellow paint.
