Answer:
[tex]\mathrm{No\: solutions}[/tex]
Step-by-step explanation:
Since Connor has worked 12 hours walking dogs, he's earned [tex]12\cdot 8 = \$96[/tex] from walking dogs. He still needs to earn [tex]\$160-\$96=\$64[/tex]. As stated in the problem, he makes $12 an hour landscaping, therefore the minimum number of whole hours he must work to fulfill his requirements is [tex]\lceil{ \frac{64}{12} \rceil = 6\: \mathrm{hours}[/tex]. However, the problem states he can only work a maximum of 15 hours. He would have to work [tex]12+6=18[/tex] to fulfill his requirements and therefore he will not be able to meet his requirements with the restrictions given.
The average of three test scores is 82. The scores on the first test and the third test are the same. The score on the second test is 6 less than the score on the first test. What is the score on the first test?
Answer:
84
Step-by-step explanation:
Let x = the test
(x + x + ( x - 6))/3=82
((3x - 6)/3) • 3= 82 • 3
3x - 6 + 6 = 246 + 6
3x = 252
3 3
x = 84
You are driving up a mountain. At the base of the mountain you see a sign that states the elevation above sea level is 3,720 feet at this point. You then travel a horizontal distance of 5 miles to the top of the mountain, and see another sign that states the elevation is 4,215 feet above sea level. What was the average slope of the mountain you just climbed in feet/mile?
A) 843 ft/mi
B) 744 ft/mi
C) 99 ft/mi
D) 0.0188 ft/mi
Step-by-step explanation:
Slope of the mountain
= Rise in height / Run in distance
= (4215ft - 3720ft) / 5 mi
= 495ft / 5mi
= 99ft/mi. (C)
Josie packed unit cubes into a prism, as shown. Which statement about the volume of the box is true?
Also so, the answer to this is; The volume of the prism is less than 72 cubic units.
Why is this the answer?
The actually cubic units for that is actually 54 cube units which if you think is; 54 < 72
So I hope this helps. I wasn´t able to see the image but according to what I know, I think it is in one of the imagine math or something else lessons. If what im telling has nothing to do with your question, I am sorry and- I guess thats that. I really hope this helps. Bye!! ^m^

Help me pleaseeeeeeeeeeee
Answer: 990 lb
Step-by-step explanation:
t = (4 x 180) + (3 x 90)
t = 720 + 270 = 990
both are x=
27. x=
28.x=
Answer:
Step-by-step explanation:
27. the sum of 2 complementary angles=90
8x-17+5x-10=90
13x=90+27
13x=117 x=9
28. the sum of supplementary angles=180
17x-12+3x-48=180
20x=180+60
20x=240
x=120

Thickness measurements of ancient prehistoric Native American pot shards discovered in a Hopi village are approximately normally distributed, with a mean of 5.4 millimeters (mm) and a standard deviation of 0.8 mm. For a randomly found shard, find the following probabilities.
a. the thickness is less than 3.0 mm
b. the thickness is more than 7.0 mm
c. the thickness is between 3.0 mm and 7.0 mm
Answer:
a) the required probability is 0.0013
b) the required probability is 0.0288
c) the required probability is 0.9759
Step-by-step explanation:
Given the data in the question;
let x be the thickness measurements
Given that X follows a Normal distribution with mean μ = 5.4
standard deviation σ = 0.8
then z = x-μ / σ = x-5.4 / 0.8 follows standard Normal
a) probability that the thickness is less than 3.0 mm
P( x<3 ) = P( x-5.4 / 0.8 < 3-5.4 / 0.8 ) = P( Z < -3.00 ) = 0.0013
Therefore, the required probability is 0.0013
b) the thickness is more than 7.0 mm
P( x>7 ) = P( x-5.4 / 0.8 > 7-5.4 / 0.8 ) = P( Z > 2.00)
= 1 - P( Z ≤ 2)
= 1 - 0.9772
= 0.0288
Therefore, the required probability is 0.0288
c) the thickness is between 3.0 mm and 7.0 mm
P(3< x<7 ) = P( x<7) - P(x<3)
= P( x-5.4 / 0.8 > 7-5.4 / 0.8 ) - P( x-5.4 / 0.8 < 3-5.4 / 0.8 )
= P( Z< 2 ) - P( Z < -3)
= 0.9772 - 0.0013
= 0.9759
Therefore, the required probability is 0.9759
PLEASE HELP DUE SOON FIRST GOOD ANSWER GETS BRAINLIEST
show that x^2 + y^2 + z^2 = 3(2x-y) -1 is a sphere
Step-by-step explanation:
x² + y² + z² = 3(2x - y) - 1
x² + y² + z² = 6x - 3y - 1
x² - 6x + y² + 3y + z² = -1
(x - 3)² + (y + 1.5)² + z² = -12.25
(x - 3)² + (y + 1.5)² + z² = -(3.5)²
Since it follows the general equation form, it is a sphere.

Is 5/9 closer to 1, 1/2, or 1?
Answer:
Closer to 1/2
Step-by-step explanation:
Half of 9 is 4.5 and 5 is .5 away from half and to make this 1 it needs to be 9/9 which is 4 away.
Answer:
1/2
Step-by-step explanation:
Half of 9 is 4.5/9, and 5/9 is closer to 4.5/9 than 9/9(or 1)

Question 10 of 10
Which of the following is an x-intercept of the function, f(x) = x2 -5x2 - 8x +48
?
A. -4
o
B. 4
C. -2
O
D. 2
Answer:
Option B: 4
Step-by-step explanation:
From the image, the correct function is;
f(x) = x³ -5x² - 8x + 48
Now, the x-intercept occurs when y = 0.
Thus;
x³ - 5x² - 8x + 48 = 0
So we are looking for values of x that will make y = 0.
Let's try the options;
Let's try x = -4;
(-4)³ - 5(-4)² - 8(-4) + 48 = -64 - 80 + 32 + 48 = -64 ≠ 0
So, x = -4 is not an x - intercept
Let's try x = 4;
(4)³ - 5(4)² - 8(4) + 48 = 64 - 80 - 32 + 48 = 0
So,x = 4 is an x-intercept
Let's try x = - 2;
(-2)³ - 5(-2)² - 8(-2) + 48 = -8 - 20 + 16 + 48 = 36 ≠ 0.
So, x = -2 is not an x-intercept.
Let's try x = 2;
(2)³ - 5(2)² - 8(2) + 48 = 8 - 20 - 16 + 48 = 20 ≠ 0
So, x = 2 is not an x-intercept

Ginger mows
3/4 acre in 1 3/4 hours. What is her unit rate of acres mowed per hour?
9514 1404 393
Answer:
3/7 acres per hour
Step-by-step explanation:
To find acres mowed per hour, divide acres mowed by hours:
(3/4 ac)/(1 3/4 h) = (3/4)/(7/4) ac/h = 3/7 ac/h
Ginger's unit rate is 3/7 acres per hour.
Answer: 3/7!

Ashley owns 14 acres of land which she rents to a Timber grower for $3131 per acre per year. Her property taxes are $882 per acre per year. How much profit does she make on the land each year?
A. $56,182
B. $42,952
C. $31,486
D. $44,716
Answer:
A. $56,182
