Answer:
Step-by-step explanation:
set jk and kl equal to each other bc they are the same length (we know this bc of the midpoint)
3x - 1 = 2x + 8
x = 9
substitute 9 in an equation
2(9) = 8 = KL
18 + 8
26 = KL
since KL is the same length as JK we can just multiply 26 * 2
JL = 52
hope this helps <3

Answer:
12
Step-by-step explanation:
8x-1+3x+4+3x+9=180
14x+12=180
14x=180-12
x=168/14
x=12
Answer:
8x-1+3x+9+3x+4=180
8x+3x+3x=180+1-9-4
14x=168
x=12

Step-by-step explanation:
Suppose h(t) = -5t^2 + 3 is the height of a diver above the water (in meters), t seconds after the diver leaves the springboard. PLEASE HELP 50 POINTS!!!!
a. How high above the water is the springboard? Explain how you know.
b. When does the diver hit the water
c. At what time on the diver's descent toward the water is the diver again at the same height as the springboard?
d. When does the diver reach the peak of the dive?
Answer:
brainliest please i work really hard for this
Step-by-step explanation:
Hit Water:
He hits the water when his height, h(t), is 0 meters above water.
0 =
This is no factorable so we use the quadratic formula.
(-b±√(b²-4ac))/2a
(-10±√(10²-4*-5*3))/2*-5
(-10±√(100+60))/-10
(-10±√160)/-10
(-10±√16*10)/-10
(-10±4√10)/-10
(-10±4√10)/-10 Seperate to two equations
(-10+ 4√10)/-10 and (-10- 4√10)/-10
(-10+12.65)/-10 (-10-12.65)/-10
-.265 Not Solution 2.265 Seconds
Becasue there is no negative time
The diver hits the water at 2.265 seconds
For when he is at the same height as the spring board, we need to find the height of the spring board, and we do that by substituting 0 for t because we need the height 0 seconds after he jumps.
h(0) = -5*0^2 +10*0 +3
h(0) = 3 The height of the spring board is 3 so we need to know when he is at 3 meters again.
3= -5t^2 + 10t + 3 Subtract 3 from both sides
0= -5t^2 +10t
0= -5(t^2-2t) Factor out -5 and divide both sides by -5
0= t^2-2t
0= t(t-2) Factor out t.
Solve.
t= 0 t-2=0
t= 2
He will be at the same height as the spring board at t= 2 seconds
27= 3 (3х - 6)
Help please
Answer:
x = 5
Step-by-step explanation:
27= 3 (3х - 6)
27 = 9x - 18
27 + 18 = 9x
45 = 9x
45/9 = x
5 = x
x = 5
Here is an expression: 20 + 4
What are some ways to think about this expression? Describe at least two meanings you
think it could have.
Answer:
look at my explanation.
Step-by-step explanation:
What is an Expression?
An expression is a sentence with a minimum of two numbers and at least one math operation. This math operation can be addition, subtraction, multiplication, and division. The structure of an expression is:
Expression = (Number, Math Operator, Number)
For example,
= 7 + 9
= 23 × 4
= 37 – 6
= 25 + 9 – 4 ÷ 2

Answer:
∠ 2 = 60°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles fro 180° for ∠ 2, that is
∠ 2 = 180° - (57 + 63)° = 180° - 120° = 60°
Montel uses 8 oz of sugar to make 36 fluid ounces of lemonade if it makes 180 fluid ounces of lemonade to bring to a party how many ounces of sugar will he use
Answer:
40 oz of sugar
Step-by-step explanation:
1) you have the basic measurement for 36 fluid ounces of lemonade, now imagine how many time can 36 go into 180 in order to find how many sugar oz you will need
180/36= 3
This mean 180 is 5 times as much lemonade and you will need 5 times as much sugar.
8ounces of sugar x 5 = 40ounces of sugar to make 180fluid ounces of lemonade
A teenager’s heart pumps an average of 7200 L of blood every 24 hours. What is the rate of change of volume of blood?
Answer:
300L per hour
Step-by-step explanation:
The rate of change of volume of blood pumped by the teenager's heart expresses the volume of blood pumped with respect to hour.
Rate of change of volume of blood = [tex]\frac{volume of blood}{time}[/tex]
= [tex]\frac{7200L}{24}[/tex]
= 300L/hour
The rate of change of volume of blood by the teenager's heart is 300 litres per hour. This implies that his/ her heart pumps 300 litres of blood every hour.

Answer:
Step-by-step explanation:
p1(-3,2) p2(2,6)
find the slope of the line between these two points
m= 6-2 /2-(-3)
m=4/5
find the slope of the line between p2 and p3(8,-1)
m=-1-6 /8-2
m=-7 / 6
dist= sqrt( (8-(-3))^2+(-1-2)^2)
dist = 11.40175 (1 to 3) hyp
dist = sqrt( (8-2)^2 + (-1-6)^2)
dist = 9.219544 (2 to 3)
dist = sqrt( (2-(-3))^2 + (6-2)^2)
dist = 6.403124 ( 1 to 2)
use law of cosines to find an angle
law of cosines cos(C) = (a^2+b^2-c^2) / (2ab) =97.61°
cos(A) = (b^2+c^2-a^2) / ( 2bc) = 32.23°
cos(B) = (a^2+c^2-b^2) / (2ac) =50.16°
do the same process as above but for the points in 23
This took me a few hours :/ granted I took a break for dinner but still .. pay me for that much work :D.. if you can't get 23 later re post question I'll work on it later

A factory uses 1/8 of a barrel of raisins in each natch of granola bars. Yesterday, the factory used 1/4 of a barrel of raisins. How many batches of granola bars did the factory make yesterday? Simplify you answer and state it as a fraction or as a whole or mixed number.
Question:
A factory uses 1/8 of a barrel of raisins in each batch of granola bars. Yesterday, the factory used 1/4 of a barrel of raisins. How many batches of granola bars did the factory make yesterday?
Answer:
The factory made 2 batches of granola yesterday.
Step-by-step explanation:
Our ratio from the question is given as:
1/8 barrel of raisins = 1 batch of granola
Hence: 1/4 barrel of raisins = x batches of granola.
Cross Multiply
1/8 × x = 1/4 × 1
x = 1/4 ÷ 1/8
x = 1/4 × 8/1
x = 2 batches of granola
Therefore, the factory made 2 batches of granola yesterday

Kiran read for x minutes,and Andre read for 5\8 more than that write an equation that relates the number of minutes Kiran read with y,then number of minutes that Andre read.
Answer:
[tex]y = \frac{5}{8} + x[/tex]
Step-by-step explanation:
Given
[tex]Kiran = x[/tex]
[tex]Andre = y[/tex]
[tex]Andre = \frac{5}{8}\ minutes\ more[/tex]
Required
Write an equation that represents the scenario
[tex]Andre = \frac{5}{8}\ minutes\ more[/tex] means that Andre read 5/8 minutes more than Kiran and this can be represented as:
[tex]Andre = \frac{5}{8} + Kiran[/tex]
Substitute x for Kiran
[tex]Andre = \frac{5}{8} + x[/tex]
Substitute y for Andre
[tex]y = \frac{5}{8} + x[/tex]

what are the areas for shape 1,2 and 3
Answer:
I think it is
1: 22.37
2:16.81
3:83.16
Step-by-step explanation:
Answer:
Shape 1: 22.365
Shape 2: 16.81
Shape 3: 83.16
Step-by-step explanation:
I'm going to start with 2, because its the easiest shape to do, which is 4.1*4.1= 16.81. Next is 3, which you find the length by adding 4.1 to 9.1 = 13.2. You then multiply 13.2 by 6.3 = 83.16. Finally for shape 1, you first find the bottom shape, which you do by dividing 6.3 by 2 so you can get the width of half the triangle. That is 3.15. then you multiply that by 7.1 to get the area of 22.365.

What is the ratio of boys to girls in Mrs. Carlton's class, which has a total of 31 students, 14 of whom are girls?
Answer:
17:14 or 17 to 14
Step-by-step explanation:
since you know there are 14 girls, subtract 14 from 31 and then you'll get 17. since its asking for a ratio of boys to girls not girls to boys, you put boys first, then girls. so your answer will be 17:14
