Find the missing lengths
Answer:
x = 13 cm
Step-by-step explanation:
The figure given is a square.
Area of the given square (A) = 169 cm²
Formula for area of a square is:
A = s²
Where,
s = x
Thus:
169 = x²
Take the square root of both sides
√169 = √x²
13 = x
x = 13 cm

Answer:
#8 is one #9 is 4
Step-by-step explanation:
2x + y =8 and 4x -2y = 6
Answer:
x=1.25 and y=-5.5
Step-by-step explanation:
2x+y=-8, 2x=-y-8 or 4x=-2y-16. Plug this value in the second equation, we have - 2y-16-2y=6, y=-5.5. Plugging this in any equation we have, x=1.25

Step-by-step explanation:
volume of cylinder = Bh = πr²h = π*7²*15 = 735π
volume of cone =1/3 Bh =1/3 πr²h =1/3 π*7²*15 = 1/3 * 735π
Answer:
the first choice- volume of the cylinder is 735pi
and the 3rd choice the volume of the come is 1/3 pf 735pi (245 is 1/3 of 735)
Step-by-step explanation:
Volume of the cylinder
[tex]V=\pi r^{2} h\\V=\pi 7^{2} 15\\V=49(15)\pi \\V=735\pi[/tex]
Volume of the cone
[tex]V=\pi r^{2} (\frac{h}{3} )\\V=\pi 7^{2} (\frac{15}{3})\\V=49 (5)\pi \\V=245\pi[/tex]

A figure is shown.
4 cm
7 cm
10 cm
2 cm
3 cm
6 cm
Which expression shows how to find the area of the figure?
Answer:
Then it is just a matter of plugging in the values into the formula. For example, if one base is 6 cm long, the other is 10 cm long and the height is 4 cm, the area is then (6 + 10) / 2 x 4 = 16 / 2 x 4 = 8 x 4 = 32 cm 2 (32 square centimeters).

Convert 9 square feet to square inches
Answer:
1296
Step-by-step explanation:
9 x 144
A square foot is a unit of area. It is the size of a square that is one foot on a side. It is 144 square inches, 1/9th of a square yard, or approximately 0.093 square meters.
A square inch is a unit of area. It is the size of a square that is one inch on a side. It is 1/144th of a square foot, or exactly 6.4516 square centimeters.
So, 9 x 144 = 1296

9514 1404 393
Answer:
1/8
Step-by-step explanation:
To find out, divide 1/3 by 8/3.
(1/3)/(8/3) = 1/8
8/3 goes into 1/3 exactly 1/8 times.
__
There are (at least) two ways to divide fractions.
1. "invert and multiply" (A.K.A. "swap dot")
[tex]\dfrac{1}{3}\div\dfrac{8}{3}=\dfrac{1}{3}\cdot\dfrac{3}{8}=\dfrac{1\cdot3}{3\cdot8}=\boxed{\dfrac{1}{8}}[/tex]
__
2. Drop common denominators.
[tex]\dfrac{1}{3}\div\dfrac{8}{3}=1\div8=\boxed{\dfrac{1}{8}}[/tex]
How do I work out 60% of 25?
Answer:
15
Step-by-step explanation:
Multiply: 25x.60=15
The reason why you multiply 25 times .60 is because you need to change the percentage to a decimal. The way you change you from a percentage to a decimal is by moving the decimal twice to the left.
So, 60%=.60
The circular opening of a tunnel
has a circumference of 42
meters. Which equation can be
used to find d, the diameter of
the tunnel opening?
Answer:
2(21/pi)=d
Step-by-step explanation:
The formula for a circumference is C=2(pi)(r) in this case we know our circumference is 42 meters so 42=2(pi)(r), we must leave our radius by itself so we divide by 2 to get 21=pi(r) we then also divide by pi which will get us 21/pi=r and we know that the diameter is double of the radius so we just double which will then be 2(21/pi)=d
