Find the missing length of the triangle.
Answer:
29 = c
Step-by-step explanation:
Since this is a right triangle we can use the Pythagorean theorem
a^2+b^2= c^2 where a and b are the legs and c is the hypotenuse
20^2 + 21^2 = c^2
400 +441 =c^2
841 = c^2
Take the square root of each side
sqrt(841) = sqrt(c^2)
29 = c
Answer:
c = 29 km
Step-by-step explanation:
21² + 20² = c²
441 + 400 = 841
√841 = 29
1. Lily spent 4 times as much as her sister Sue. If the girls spent $24, how much did each girl spend?
Answer:
Lily spent $19.20, Sue spent $4.80. Make sure to include the units.
Step by Step:
Lets say Sue is X
4x+x=24
5x=24
x=24/5
x=4.8
So sue spent 4.8.
24-4.8=19.2
Lily spent 19.2
Check: 4(4.8)=19.2
19.2+4.8=24

What is the value of n in the equation 1/2 (n - 4) - 3 = 3 - (2n + 3)?
A. n = 0
B. n = 2
C. n = 4
D. n = 6
HELP PLEASE!!!!
Answer:
n=2
1/2n-2-3=3-2n-3
1/2n+2n=3+2+3-3
2/1/2n=5
5/2n=5
n=5 multiply 2/5
n=2
if anyone could help me to figure out whether or not this is correct i would appreciate that. thank you :)
Answer:
You are correct.
Step-by-step explanation:
Probably too late, but 475 x 3 = 1425. Since it is a loss, the negative sign is appropriate.

Problem 3
Answer: 1/5 of a gallon per minute-------------------------
Explanation:
Two points from the graph are (10,2) and (20,4)
Apply the slope formula
m = (y2-y1)/(x2-x1)
m = (4-2)/(20-10)
m = 2/10
m = 1/5
The slope of the graph is 1/5.
Do the same for two points from the table. I'll use the first two rows
m = (y2-y1)/(x2-x1)
m = (4-2)/(10-5)
m = 2/5
The slope of the table is 2/5.
Subtract the two slopes to wrap things up:
2/5 - 1/5 = (2-1)/5 = 1/5
=====================================================
Problem 5
Answer: 23 degrees------------------------
Explanation:
Angles 1 and 3 are same side exterior angles, so they are supplementary due to the parallel lines set up here.
(angle1)+(angle3) = 180
(157) + (angle3) = 180
angle3 = 180-157
angle3 = 23 degrees

Answer:
9 pi
Step-by-step explanation:
First find the circumference of the circle
C =2 * pi *r
C = 2 * pi *9
C = 18 pi
This is a semicircle which is 1/2 of a circle
Take 1/2 of the circumference
1/2 C = 1/2 ( 18 pi)
1/2 C = 9 pi

Answer:
6 x 4 = 24, 24 x 2 = 48
7 x 6 = 42
7 x 4 = 28, 28 x 2 = 56
6 x 4 x 1/2(basically just dividing by 2) = 12, 12 x 2(two triangles) = 24
5 x 5 = 25, 25 x 2 = 50
Add given areas:
48 + 42 + 56 + 24 + 50 = 220 ft^2 is your answer.

Given v = u + 5t; Find v when u= -15 and t=4
v = u + 5t
v = -15 + 5(4)
v = -15 + 20
v = 5

[tex]v = u + 5t[/tex]
Given,
[tex]u = - 15 \\ t = 4 \\ v = \: ?[/tex]
To find the value of v, we must substitute the values of u & t in the equation ⇻ v = u + 5t.
[tex]v = u + 5t \\ v = ( - 15) + 5(4) \\ v = - 15 + 20 \\ v = 5[/tex]

What is the area of the shaded portion of the circle?
9514 1404 393
Answer:
(a) (5π -11.6) ft²
Step-by-step explanation:
The shaded area is the area of 1/5 of the circle less the area of the triangle with base 5.8 ft and height 4 ft.
shaded area = 1/5(π(5 ft)²) -(1/2)(5.8 ft)(4 ft)
shaded area = (5π -11.6) ft²

Answer:
[tex]\huge\boxed{Answer\hookleftarrow}[/tex]
Given,
[tex]3x - 2y = 5[/tex]
[tex]xy = - 2[/tex]
Now,
[tex](3x - 2y) {}^{2} = (5) {}^{2} \\ [/tex]
Use the algebraic identity ⇻ (a - b)² = a² - 2ab + b²
[tex](3x - 2y) {}^{2} = (5) {}^{2} \\ 3x {}^{2} - 2 \times 3x \times 2y + 2y {}^{2} = 5 {}^{2} \\ 9 {x}^{2} - 12xy + 4y {}^{2} = 25 \\9x {}^{2} + 4y {}^{2} = 25 + 12xy \\ 9x {}^{2} + 4 {y}^{2} - 1 = 24 + 12xy[/tex]
✐ So, the value of 9x² + 4y² - 1 is 24 + 12xy
Now,
xy = - 2
So, 12xy = 12 × - 2 = - 24
•°• 24 + 12xy
= 24 + (-24)
= 24 - 24
= 0
