Answer: 14 feet
Step-by-step explanation:
Let the shorter piece of the board be represented by x.
Since the longer piece is 2 feet more than twice the first, this will be:
= (2 × x) + 2
= 2x + 2
We then add both pieces and equate them to 20. This will be:
x + (2x + 2) = 20
x + 2x + 2 = 20
3x + 2 = 20
3x = 20 - 2
3x = 18
x = 18/3
x = 6 feet
Shorter piece = 6 feet
Longer piece = 2x + 2 = 2(6) + 2
= 12 feet + 2 feet
= 14 feet
The longer piece of board is 14 feet

RESEARCH STUDY 11.2: Dr. Bloedorn is a health psychologist who researches nutrition. She is curious as to whether a new drink additive will help people consume fewer calories during a meal. The drink additive is a white, odorless, tasteless powder that a person can add to any drink. She collects a random sample of 63 overweight students on campus and measures the calories they eat during lunch using a bomb calorimeter. She then gives this additive to the same 63 participants to use at dinner and measures how many calories they eat (again using the bomb calorimeter). Imagine that Dr. Bloedorn finds no difference between the calories consumed with the drink additive and without. This is known as
Answer:
This is known as null effect
Step-by-step explanation:
A null effect is the outcome of an experiment that does not give the effect or result expected. Although an experiment with a null effect has a result, however the result of the experiment does not support the hypothesis
An example of a null result that remains importantly useful is the Michelson-Morley experiment from that partly made possible the formulation of special relativity theory

If your roll a six sided die what is the probability of getting a 2 or a 6
(A) 1/3
(B) 1/4
(C) 1/6
(D) 2/3
Answer:
(A)1/3
Step-by-step explanation:
probability of getting a 2 = 1/6
probability of getting a 6 = 1/6
so the probability of getting a 2 or a 6
=(probability of getting a 2+probability of getting a 6)
=(1/6+1/6)
=2*(1/6)
=1/3

[tex](y - 1)^{3} = (y - 1)( {y}^{2} + y \: \: 1 + {1}^{2} ) \\ \\(y - {1)}^{3} = (y - 1)( {y}^{2} + y + 1)[/tex]
HELP ME ANSWER THE PROBLEM IN THE PICTURE 25 POINTSS
Answer:
x = 3, y = - 1
Step-by-step explanation:
Given the 2 equations
6x + 4y = 14 → (1)
- 5x + 12y = - 27 → (2)
Multiplying (1) by - 3 and adding to (2) will eliminate the y- term
- 18x - 12y = - 42 → (3)
Add (2) and (3) term by term to eliminate y
- 23x + 0 = - 69
- 23x = - 69 ( divide both sides by - 23 )
x = 3
Substitute x = 3 into either of the 2 equations and solve for y
Substituting into (1)
6(3) + 4y = 14
18 + 4y = 14 ( subtract 18 from both sides )
4y = - 4 ( divide both sides by 4 )
y = - 1
solution is (3, - 1 )

On a map, 1 inch represents 3 miles. How many miles long is a road that is 2.5 inches long on the map?
Answer:
7.5
Step-by-step explanation:
you have to double it to get 6 then half of 3 is 1.5 so 6 plus 1.5 is 7.5
Answer:
7.5 miles
Step-by-step explanation:
1 inch = 3 miles
1 inch = 3 miles
1/2 inch = 1.5 miles
3+3+1.5 = 7.5 miles

Step-by-step explanation:
To find the diameter of a circle, you multiply the radius (the radius is the distance from the outside of the circle to the middle) by 2.
Ex: the first one has 6m as the radius. So you would multiply the 6 by 2. Which would be 12.
The radius is half of the diameter. So for number 8, the answer would be 2.
hope this helps and that it wasn't to confusing :)
Choose the expression that is NOT equivalent to the following expression:
45y + 99
5(9y + 19.8)
9(5y + 11)
2(22.5y + 49.5)
4(11y + 22)
Answer:
4(11y +22)
Step-by-step explanation:
5(9y+19.8) =45y+99
9(5y+11)=45y+99
2(22.5y+49.5)=45y+99
4(11y+22)=44y+88
you must expand the numbers to get the total
for example you multiply 5×9y and 5×19.8 in a
please please help!! and if you could show work too that would be amazing!!!
Answer:
AB, BC, AC
Step-by-step explanation:
Hi there,
In order to solve this problem, we should know that the longest side of the triangle is always opposite of the largest angle in a triangle. The first step is to find the angle measures. We are given the measures of ∠A and ∠C.
To find m∠B, just subtract the sum of the other angles and subtract the value from 180.
m∠A + m∠C + m∠B = 180°
65° + 40° + m∠B = 180°
105° + m∠B = 180°
m∠B = 75°
Now that we know all of the angle measures, we can identify the the lengths of the sides from least to greatest by looking at the angle value. The greater the angle measure, the longer the opposite side would be.
m∠A = 65° ⇒ opposite of side BC = medium side
m∠B = 75° ⇒ opposite of side AC = longest side
m∠C = 40° ⇒ opposite of side AB = shortest side
Hope this explanation helps. Cheers.

Answer:
C
Step-by-step explanation:
The length of arc AC (L) is calculated as
L = circumference of circle × fraction of circle
= 2πr × [tex]\frac{150}{360}[/tex]
= 2π × 12 × [tex]\frac{5}{12}[/tex]
= 2π × 5
= 10π ≈ 31.42 → C

Find the value of x.
Answer:
x= 128*
Step-by-step explanation:
180*-52*=128*
Answer:
x = 128
Step-by-step explanation:
well we know that for a polygon, the interior angles always add up to 360.
One angle is 52, and since the other two have squares it means that they are a perfect 90 degree angle. add those up to get 232, and then subtract 232 from 180 to get 128
Solve the equation: 4(x-2)=12
