Answer:
Use this formula to calculate for the surface area of cylinder.
Step-by-step explanation:
A=2π r h+2 π r^2.
use r = 10 m and h = 7 m
2 (3.14) (10) 7 + 2 (3.14) 10 ^2. = 439.6 + 628 = 1067.6
round to the nearest hundredths = 1068

Two triangles: left triangle with y degrees and 40 degrees and right triangle with x degrees.
40 degrees from the left triangle, when adding with the unknown angle of the right triangle, is equal to 180 degrees. Adding left triangle's (third) undetermined angle and x degrees angle (the other same angle), is equal to 90 degrees. The right triangle is an isosceles triangle, meaning two equal angles, and one of them is x degrees. Thus, the other same angle is also x degrees.----------------------------------------------------------------------------------------------------------
1) Subtract 180 - 40 = 140 degrees. 140 degrees is the unknown angle of right triangle.
2) 140 + x + x = 180 (equation)
140 + 2x = 1802x = 180 - 1402x = 40 x degrees = 20 degreesANSWER: x = 20 DEGREES
----------------------------------------------------------------------------------------------------------
1) With knowledge of x degrees being 20 degrees, the other same angle is 20 degrees, too.
2) Subtract 90 - 20 = 70 degrees. 70 degrees is the (third) undetermined angle
of left triangle.
2) 70 + 40 + y = 180
110 + y = 180y = 180 - 110y = 70 degreesANSWER: y = 70 DEGREES

Quadrilateral BCDE is similar to quadrilateral FGHI. Find the measure of side FG. Round your answer to the nearest tenth.
Answers
Answer:
The answer is below
Step-by-step explanation:
Two polygons are said to be similar to each other if they have the same shape as well as the ratio of their corresponding sides being equal to each other.
Since quadrilateral BCDE is similar to quadrilateral FGHI, hence the ratio of their corresponding sides is equal. Hence:
[tex]\frac{FG}{BC}= \frac{HI}{DE} \\\\substituting:\\\\\frac{FG}{8.3} =\frac{50}{11} \\\\FG=\frac{50*8.3}{11}\\\\FG=37.7\ to \ the\ nearest\ tenth[/tex]

In circle E with m \angle DEF= 70m∠DEF=70 and DE=13DE=13 units find area of sector DEF. Round to the nearest hundredth.
Answers
Answer:
103.18units³
Step-by-step explanation:
Area of the sector DEF = theta/360 * πr²
r is the radius
theta is the angle subtended at the centre
theta =70 degrees
radius DE = 13units
Substitute
Area of the sector = 70/360 * 3.14(13)²
Area of the sector = 7/36 * 530.66
Area of the sector = 3,714.62/36
Area of the sector = 103.18units³ (to the nearest hundredth)

The number 7 goes above 84.
120 under 10.
12 above 144.
Explanation: Refer to the next question. Each ratio will equal out to 1/12 so you either divide or multiply 12 for each one.
5x12=60
84/12=7
10x12=120
144/12=12
1. 1/12
Explanation:
2 packets of flavoring to 24 ounces of water, 24/2 is 12.
4. 276 ounces of water
Explanation:
12 ounces of water to every packet of flavoring so we need to multiply 23 by 12 which equals 276.
5. Yes. (9.5, 114) makes sense because it follows the ratio of 1:12. 114/9.5=12; 9.5x12=114.
6. 36/3, 66/5, 108/9, 180/15
Explanation:
24/2 = 12, multiply each bottom number by 12 and divide each top number by 12.
7. It uses multiplication because you are multiplying by 12.

It looks like the equation is supposed to read
3⁴ˣ ⁻ ⁵ = (1/27)²ˣ ⁺ ¹⁰
Recall that 3³ = 27, so 1/27 = 3⁻³ :
3⁴ˣ ⁻ ⁵ = (3⁻³)²ˣ ⁺ ¹⁰
Distribute the exponent on the right side:
3⁴ˣ ⁻ ⁵ = 3 ⁻⁶ˣ ⁻ ³⁰
The exponents must be equal for this equation to hold, so
4x - 5 = -6x - 30
Solve for x :
10x = -25
x = -25/10 = -5/2

The lenght of a rectangle is 2 units more than the width. The area of the rectangle is 48 units. What is the length, in units, of the rectangle?
Answers
Answer:
The length of this rectangle is 6 units.
Step-by-step explanation:
Let the width of the rectangle be x.
x • (x+2) = 48
x^2+2x=48
x^2+2x-48=0
x^2 - 6x + 8x - 48
x(x-6) 8(x-6)
(x+8)(x-6)
x=-8,6
