5. Mr. Crossley is building a new dog house for Chester.
He starts with a piece of wood that is 8 feet long. How
many pieces of woods can he cut if he needs each piece
to be 2 feet?
Answers
Answer:
4 Pieces
Step-by-step explanation:
8 ÷ 2 = 4
Answer:
Step-by-step explanation:
Hello there!
He has 8 ft of wood, and he needs each peice to be 2 ft long. To solve this, we divide 8 ft by 2 ft (this will determine how many 2 ft peices can be cut from 8 ft). 8 ÷ 2 = 4, so this means he can cut four peices of wood to build the doghouse for Chester!

solve -5(x-7)^2+30=-20
Answers
Answer:
x=7−√10 or x=7+√10
Step-by-step explanation:
−5(x−7)2+30=−20
Step 1: Simplify both sides of the equation.
−5x2+70x−215=−20
Step 2: Subtract -20 from both sides.
−5x2+70x−215−(−20)=−20−(−20)
−5x2+70x−195=0
For this equation: a=-5, b=70, c=-195
−5x2+70x+−195=0
Step 3: Use quadratic formula with a=-5, b=70, c=-195.
x=
−b±√b2−4ac
2a
x=
−(70)±√(70)2−4(−5)(−195)
2(−5)
x=
−70±√1000
−10
x=7−√10 or x=7+√10

Answers
Answer:
x = 1, XZ = 48
Step-by-step explanation:
So you already have the diagram with the number labeled,
4(x + 5) and 2(x + 11)
We know that Y is the midpoint between X and Z so we know that XY = YZ:
4(x + 5) = 2(x + 11)
Let's solve the equation for x:
4x + 20 = 2x + 22 (Distributive Property)
Subtract 20 from both sides:
4x = 2x + 2
Subtract 2x from both sides:
2x = 2
Divide both sides by 2:
x = 1
So now we know that x = 1, we want to find XZ:
XZ = 4(x + 5) + 2(x + 11)
We can plug in x (1):
XZ = 4(1 + 5) + 2(1 + 11)
Simplify:
XZ = 4(6) + 2(12)
XZ = 24 + 24
XZ = 48

if (8^9)^p=8^18what is the value of p
Answers
Answer:
[tex]\huge\boxed{p=2}[/tex]
Step-by-step explanation:
In order to simplify this equation [tex](8^9)^p = 8^{18}[/tex], we have to use basic exponent rules.
Exponent rules tell us that [tex](a^b)^c = a^{b\cdot c}[/tex].
We have [tex](8^9)^p[/tex], so this means that it's equivalent to [tex]8^{9 \cdot p}[/tex] or just [tex]8^{9p}[/tex].
Now, we have [tex]8^{9p}=8^{18}[/tex]
Let's just focus on the exponents for now.
Since we know that in order for [tex]8^{9p}[/tex] to be equivalent to [tex]8^{18}[/tex], the exponents must be the exact same. So, [tex]9p=18[/tex].
We can find p by divide both sides by 9.
[tex]p = 2[/tex]
Hope this helped!
Which expressions are equivalent to 18 + 24?

C

D
6(3+4)
2(16 + 22)
OF
2(9 + 12)
Answers
Answer: A and D are correct because they both equal 42.
Step-by-step explanation: Both A and D when distributed equal 18 + 24.
B is incorrect because that equals 18 + 63
C is incorrect because that equals 72 + 12
The last one is incorrect because when simplified it is 76 of 30 and 76 of 30 equals 22.8, not 42.
Answer:
A only
Step-by-step explanation:
Not sure if your missing letter options. If D is asking all 3 to be right, then no, D is not correct. If there are 2 letters missing then the last equation also works.
I reread the question and option D seems like it is
6(3+4) * 2(16 + 22)
2(9 + 12)
Which equals
(42 * 76) / 42 = 72
So not D

= (7)^2 * (x^3)^2 * (y^3)^2
= 49 * x^(3*2) * y^(3*2)
= 49x^6y^6
You have to distribute the terms in "7x^3 * y^3" each to the power of 2

You want to find out whether caffeine mitigates the effect of alcohol on reaction time. To study this, you administer to your subjects a drink that is equivalent to three 12-ounce beers, followed by the equivalent of two cups of coffee. Then your subjects complete a simulated driving task in which they must follow a fixed speed limit while driving on a straight road. Wind periodically and randomly pushes the simulated vehicle right, left, or not at all. Speed is measured in miles per hour above or below the 60-mph speed limit, with 1 mph being the smallest unit on the scale. Suppose the first subject scores 9 mph. Determine the real limits of 9. When measuring weight on a scale that is accurate to the nearest 0.2 pound, what are the real limits for the weight of 120 pounds? When measuring weight on a scale that is accurate to the nearest 0.5 pound, what are the real/limits for the we.ght of 187 pounds?
Answers
Answer:
First Question
lower limit of 9 mph [tex]j = 8.5 \ mph[/tex]
upper limit of 9 mph [tex]q = 9.5 \ mph[/tex]
Second Question
lower limit of 120 pounds is [tex]i = 119.9 \ pounds[/tex]
upper limit of 120 pounds is [tex]l = 120.1 \ pounds[/tex]
Third Question
lower limit of 187 pounds is [tex]a = 186.75 \ pounds[/tex]
upper limit of 187 pounds is [tex]b = 187.25 \ pounds[/tex]
Step-by-step explanation:
From the question we are told that
The amount of beer administered is three 12-ounce beers
The amount of coffee administered is two cups of coffee
The speed limit is 60-mph
The smallest unit of scale is 1 mph
The first subject scores 9 mph
Generally given that the smallest unit of scale is 1 mph then the deviation of 9 mph will be by [tex]\frac{1}{2} \ mph[/tex]
Hence the lower limit of 9 mph is
[tex]j = 9 - 0.5[/tex]
[tex]j = 8.5 \ mph[/tex]
And the upper limit of 9 mph is
[tex]q = 9 + 0.5[/tex]
[tex]q = 9.5 \ mph[/tex]
Generally given that the measuring weight on a scale that is accurate to the nearest 0.2 pound then 120 pounds will deviate by [tex]\frac{1}{0.2} \ pounds[/tex]
Hence the lower limit of 120 pounds is
[tex]i = 120 - 0.1[/tex]
[tex]i = 119.9 \ pounds[/tex]
And the upper limit of 120 pounds is
[tex]l = 120 + 0.1 [/tex]
[tex]l = 120.1 \ pounds[/tex]
Generally given that the measuring weight on a scale that is accurate to the nearest 0.5 pound then 187 pounds will deviate by [tex]\frac{1}{0.5} \ pounds = 0.25 \ pounds [/tex]
Hence the lower limit of 120 pounds is
[tex]a = 187 - 0.25[/tex]
[tex]a = 186.75 \ pounds[/tex]
And the upper limit of 120 pounds is
[tex]b = 187 + 0.25 [/tex]
[tex]b = 187.25 \ pounds[/tex]
Caffeine migrates the effects of alcohol.
Caffeine being a drug in itself is able to remove the effects of alcohol drugs. In order to study the effects of drinking coffee can be used to cure and treat the patients suffering.
Thus caffeine has more medicinal usage.
The study administered to the subject that drink coffee equivalent to three 12 ounces of beer was taken in 2 cups of coffee. The subjects were asked to do driving takes which has some mixed reactions.The goal was to find a cause-and-effect relationship. The study proves that the caffeine kept them more awake as per the use of alcohol of the beer.Hence as per the effect of chemicals, the effects of weights increased. Thus was able to migrate the reaction time.Learn more about whether caffeine.

3x +21 6x-60 find the value of x 25 26 27 28 will.mark brainest
Answers
Answer:
Heloo
Step-by-step explanation:
Simplifying
3x + 21 = 6x + -60
Reorder the terms:
21 + 3x = 6x + -60
Reorder the terms:
21 + 3x = -60 + 6x
Solving
21 + 3x = -60 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
21 + 3x + -6x = -60 + 6x + -6x
Combine like terms: 3x + -6x = -3x
21 + -3x = -60 + 6x + -6x
Combine like terms: 6x + -6x = 0
21 + -3x = -60 + 0
21 + -3x = -60
Add '-21' to each side of the equation.
21 + -21 + -3x = -60 + -21
Combine like terms: 21 + -21 = 0
0 + -3x = -60 + -21
-3x = -60 + -21
Combine like terms: -60 + -21 = -81
-3x = -81
Divide each side by '-3'.
x = 27
Simplifying
x = 27
Answer:
x = 27Step-by-step explanation:
3x + 21 = 6x - 60
3x - 6x = -60 - 21
-3x = -81
x = 27

length of each side.
Answers
Answer:
15,20,25
Step-by-step explanation:
The ratio of the sides is 3:4:5
So 3x + 4x + 5x = 60
12x = 60
x = 60/12
x = 5
The sides are therefore
3x = 3*5 = 15
4x = 4*5 = 20
5x = 5*4 = 25
