Answer: x=4
Step-by-step explanation:
0=2x²-16x+32 >Take out GCF
0=2(x²-8x+16) >Find 2 numbers that multiple to last term, +16,
but add to middle term, -8
-4 and -4 multiply to +16 and add to -8
put -4 and -4 into factored form
0=2(x-4)(x-4) >Divide both sides by 2
0=(x-4)(x-4) >Normally you would set both parenthesis to 0
but they are the same so set the x-4=0
x-4=0
x=4

Step-by-step explanation:

i think you made a mistake on "it got colder by 2C." If temperatures get colder, they drop, meaning you subtract it.
also, it said between the hours of 6-10pm, which is three hours, the temperature drops each hour by 3C. so, you multiply 3 to -3, and come up with -9

Grace made a dot plot showing the distances she ran each day for two weeks.
She says that she usually runs 7 miles each day because that is the distance that occurs most often.
Do you agree with Grace’s reasoning?
Use the drop-down menus to explain and show your answer.
Dot plot named as ALTDCDistances RunALTDC has number line from 1 to 7. 1 dot on 1, 3 dots on 2, 3 dots on 3, 3 dots on 4 and 4 dots on 7 are given.
The mode, which is (3,4, or 7) ,(is or is not) a typical distance for the data. The median, which is (3.5,4, or 7),(is or is not) a typical distance for the data. The mean, which is (3,4, or 7) ,(is or is not) a typical distance for the data. So, Grace’s reasoning(is or is not ) correct.
Answer:
The mode, which is 7, is not a typical distance for the data. The median, which is 3.5, is not a typical distance for the data. The mean, which is 4, is a typical distance for the data. So, Grace’s reasoning is not correct.

Ali Clara and Shane raise money for new books for the school library all Ellie rays 20% more than Clara and $58 more than Shan Claries 1/4 times
Answer:
a. $435
b. 33.33%
Step-by-step explanation:
P.S - The exact question is -
Let Clara raised money = x
As given,
Ali raised 20% more than Clara
⇒Ali raised money = [tex]x + \frac{20}{100}x = x + \frac{1}{5} x = \frac{6}{5}x[/tex]
Also given,
Clara raised [tex]\frac{1}{4}[/tex] times more than Shan
Clara raised money = Shan raise money + [tex]\frac{1}{4}[/tex] times shan raired money
⇒Clara raised money = [tex]\frac{5}{4}[/tex] Shan raised money
⇒Shan raised money = [tex]\frac{4}{5}[/tex] times Clara
⇒Shan raised money = [tex]\frac{4}{5}[/tex] x
As given,
Ali raised $58 more than shan
⇒[tex]\frac{6}{5}x = \frac{4}{5}x + 58[/tex]
⇒[tex]\frac{6}{5}x -\frac{4}{5} x = 58[/tex]
⇒[tex]\frac{2}{5}x = 58[/tex]
⇒x = (29)(5) = $145
∴ we get
Clara raised money = x = $145
Ali raised money = [tex]\frac{6}{5}x[/tex] = $174
Shan raised money =[tex]\frac{4}{5}[/tex] x = $116
a.)
Total raised money = $145 + 174 + 116 = $435
b.)
Percentage of money Clara raised = [tex]\frac{145}{435}[/tex]×100% = [tex]\frac{1}{3}[/tex]×100% = 33.33%
Find the quotient of 3 2/5 and 3 1/6 . Express your answer in simplest form.
1 5/12
95/102
1 7/95
10 23/30
Answer:
1 7/95
Step-by-step explanation:
convert the fractions into improper fractions
3 2/5 = 17/5
3 1/6 = 19/6
[tex]\frac{17}{5}[/tex] divided by [tex]\frac{19}{6}[/tex] - invert second term and multiply
so 17 * 6 = 102
5* 19 = 95
answer is 102/95, or 1 7/95

white chocolate costs $2.00 per bar, and dark chocolate costs $2.50 per bar. If you buy 15 bars of chocolate for $34, how many of each bar did you buy?
Answer:
7 white and 8 dark bars
Step-by-step explanation:
x white bars
15-x dark bars
cost of white bars is 2 * x
cost of dark bars is 2,5 * (15-x)
Write an equation
2x + 2,5 * (15-x) = 34
2x + 37,5 - 2,5x = 34
-0,5 x = - 3,5
x = 7
So we have x = 7 white bars
and 15 - x = 15 - 7 = 8 dark bars
Find the roots of the equation: f(x)=64x2+6=31
Answer:
5/8, -5/8
Step-by-step explanation:
64x^2 = 25
divide both sides by 64
x^2 = 25/64
take the square root of both sides, and the negative square roots
Answer:
x = 5/8=0.625 and x = -5/8=−0.625
Step-by-step explanation:
f(x)=64x^2+6=31
Subtract 6 from both sides.
64x^2+6=31
Subtract 6 from 31 to get 25.
64x^2=25
Divide both sides by 64.
x^2=25/64
Take the square root of both sides of the equation.
x=5/8=0.625
x=-5/8=−0.625
A man knows that his apple tree is 51 ft high. At 11:00 am the tree casts a shadow of 68 ft. What is the angle of elevation of the sun? Round to the nearest tenth
Answer:
36.9 degrees
Step-by-step explanation:
This problem can be solved by drawing a right triangle and doing trigonometry. We can draw our triangle with a height of 51 and a base of 68. In order to find the angle from the ground to the sun we can use arctangent (tan^-1). Since tan(angle)=opposite/adjacent we can find the angle by doing angle=tan^-1(51/68)
Help me please :( I’m going to get beat if I don’t do these topics it’s finding the angles measures given two parallel lines

A 1kg book is lifted 2m. How much work was done?
Answer:
work= force ×distance
force= mass × acceleration due to gravity
mass= 1kg
acceleration=10
Force=1×10=10N
Work=10×2=20joules
The work done is 20 joule.
What is Work done?
It should be converted to energy in order to move an object. Energy can be transferred by the use of force. Work done refers to the amount of energy used by a force to move an object.
Given:
mass, m= 1 Kg
So, force = mg = 1 x 10 = 10 N
and, displacement = 2m
Now, work done= force x displacement
= 10 x 2
= 20 Joules.
Hence, the work done is 20 joule.

The sum of two numbers is 1130. Their difference is 470. Write a system of equations that
could be used to find the value of the two numbers then find the value of the smallest number
(1 Point)
300
330
180
500
17
Answer:
x = 800 and y = 330
Step-by-step explanation:
Let two numbers be x and y.
Sum of two numbers is 1130.
Their difference is 470.
So,
x+y=1130 ...(1)
x-y = 470 ...(2)
Add equation (1) and (2).
x+y+x-y = 1130+470
2x = 1600
x = 800
Put the value of x in equation (1)
800+y=1130
y = 1130-800
y = 330
So, the smallest number is 330 and the largest number is 800.
