A cabinetmaker is asked to build a cabinet with dimensions of 8 inches wide by 14 inches long by 40 inches tall. He is then asked to reduce the size of the cabinet by a scale factor of 3/4. What are the new dimensions of the cabinet?
Answers
Answer:
6 inches by 10 1/2 inches by 30 inches
Step-by-step explanation: To find this answer you have to multiply the old dimensions by the scale factor which is 3/4. You would do 8 times 3/4 which is 6 inches. Then 14 inches times 3/4 which is 10 1/2. And then 40 inches times 3/4 and that answer is 30 inches. Those are the new dimensions for the cabinet.

g(x) = 2x² +16x+35
(a) Write the equation in the form g (x)= a (x - h)2 + k.
Answers
Answer:
The equation g(x) = 2(x+4)² +3
(h,k) = (-4,3) and a = 2
Step-by-step explanation:
Step(i):-
Given equation g(x) = 2 x² + 16 x +35
g(x) = 2(x² +8 x ) +35
g(x) = 2(x² +2(4) (x ) +(4)² -(4)²)+35
we know that (a+b)² = a²+2ab+b²
Step(ii):-
g(x) = 2( x+4)² - 2(16) +35
⇒ g(x) = 2(x+4)² - 32 +35
⇒ g(x) = 2(x+4)² +3
comparing g(x) = a (x-h)² +k
(h,k) = (-4,3) and a = 2
Final answer:-
The equation g(x) = 2(x+4)² +3
(h,k) = (-4,3) and a = 2

Given the equation,
y = 1/3x - 4, what is the slope and the y-intercept?
m= 4 and b= 1/3
m= -4 and b=1/3
m= 1/3 and b= 4
m= 1/3 and b= -4
Answers
Answer:
m = 1/3 and b = - 4
Step-by-step explanation:
The equation already gives the answer as the equation is in slope-intercept form.
[tex]y = mx + b[/tex]
Where m = slope and b = y-intercept.
From the equation —
[tex]y = \frac{1}{3} x - 4 \\ m = \frac{1}{ 3} \\ b = - 4[/tex]
Therefore, our slope is 1/3 and y-intercept is - 4.

Answer:
2 Radical 50
Step-by-step explanation:
Now we need to reduce the 100,since 2 is not reducible its automatically goes outside the radical. To reduce the 100 we can multiply 50 times 2.You can see now that the 2 in the radical is also not reducible so that also has to go outside the radical. When you get two numbers that are alike you don't necessarily combine them but only use one of them.

A scuba diver was at a depth of −8012 feet. How many feet did the scuba diver ascend if the diver traveled to the surface of the ocean?
Answers
The scuba driver traveled to the sea level which is 8012 feet
what is sea level?Sea level is measured in relation to the adjacent land. Just like the ocean, the elevation of land may rise and fall over time. For example, the tremendous weight of a glacier on land pushes the land down, closer to sea level. And the sea level at the surface of the ocean is considered to be zero.
Given here, he dived to a depth -8012 feet so he has to ascend again by + 8012 feet to reach the surface of the ocean .
Hence, he traveled 8012 feet.

Solve for a: b − 2a = c
Answers
Answer:
[tex]a=-\frac{c-b}{2}[/tex]
Step-by-step explanation:
Solving for the variable [tex]a[/tex], given that :
[tex]b-2a=c[/tex]
We can first start start by subtracting [tex]b[/tex] from both sides of the equation:
[tex]-2a=c-b[/tex]
Now, we can divide both sides of the equation by the coefficient of [tex]a[/tex], which would be [tex]-2[/tex]:
[tex]a=\frac{c}{-2}-\frac{b}{-2}[/tex]
Applying the fraction rule [tex]\frac{a}{c}\pm\frac{b}{c} =\frac{a\pm b}{c}[/tex]:
[tex]a=\frac{c-b}{-2}[/tex]
Then, apply the fraction rule [tex]\frac{a}{-b} =-\frac{a}{b}[/tex]
[tex]a=-\frac{c-b}{2}[/tex]

Find the 37th term of the arithmetic sequence: -38,-8,22,52
Answers
Answer:
1042
Step-by-step explanation:
-38,-8,22,52
The common difference is 52 - 22 = 30
a_1 = -38
a_2 = -38 + 30
a_3 = -38 + 2 * 30
a_4 = -38 + 3 * 30 (notice that the common difference is multiplied by 1 less than the term number)
a_n = -38 + (n - 1)30 (since the term number is n, we multiply the common difference by n - 1)
a_n = -38 + 30(n - 1)
a_37 = -38 + 30(37 - 1)
a_37 = 1042

Devi rides the bus to her grandmother's house every day. She tracked how many minutes the bus rides took for one week: 24 32 25 24 30 30 24 calculate the mean, median, range, and mid range of the bus ride times for a week
Answers
Answer:
Mean: 27
Median: 25
Range: 8
Mid Range: 28
Step-by-step explanation:
The value of mean, median, range and mid range will be 27 , 24 , 8 and 28 respectively.
It is given that the time in minutes for which Devi rides the bus in a week is 24, 32, 25, 24, 30, 30, 24.
We have to find out the value of mean, median, range and mid range.
What is mean of numbers ?
The mean of numbers is the ratio of sum of all numbers to the total no. of numbers.
As per the question ;
The time in minutes for which Devi rides the bus in a week is ;
24, 32, 25, 24, 30, 30, 24.
So ;
The mean will be ;
= [tex]\frac{24 + 32 + 25 + 24 + 30 + 30 +24}{7}[/tex]
= [tex]\frac{189}{7}[/tex]
= 27
and
We know that when n is odd number then ; Median is ;
= [tex]\frac{n+1}{2}th[/tex] term
= [tex]\frac{8}{2}th[/tex] term
= 4th term
= 24
and
Range will be ;
= largest number - smallest number
= 32 - 24
= 8
and
Mid range will be ;
= (largest number + smallest number) / 2
= [tex]\frac{32 + 24}{2}[/tex]
= 56 / 2
= 28
Thus , the value of mean, median, range and mid range will be 27 , 24 , 8 and 28 respectively.
