Answer:
a) (-25)(4)
Step-by-step explanation:
To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations. In this case,
withdrew means no longer there which means subtracted.
Then, times mean multiply.
Therefore, -minus twenty-five times (x) four
combine them and it equals (-25)(4)

The volume of the Hawk’s refrigerator is 30 × 68 × 28.5 cubic inches.
The volume of the Lopez’s refrigerator is (30 × 68 × 28.5) + 16 cubic inches.
Without doing any calculations, which statement describes how the volume of
the Hawk’s refrigerator compares to the Lopez’s refrigerator?
A.
The volume of the Hawk's refrigerator is 16 cubic inches greater than the volume of the Lopez's refrigerator.
B.
The volume of the Hawk's refrigerator is 16 times less than the volume of the Lopez's refrigerator.
C.
The volume of the Hawk's refrigerator is 16 times greater than the volume of the Lopez's refrigerator.
D.
The volume of the Hawk's refrigerator is 16 cubic inches less than the volume of the Lopez's refrigerator.
Answer:D
Step-by-step explanation:
The correct statement that describes how the volume of the Hawk's refrigerator compares to the Lopez's refrigerator is: Option D.
D. The volume of the Hawk's refrigerator is 16 cubic inches less than the volume of the Lopez's refrigerator.
From the given information, we get,
The volume of the Hawk's refrigerator is given as 30 × 68 × 28.5 cubic inches.
The volume of the Lopez's refrigerator is given as (30 × 68 × 28.5) + 16 cubic inches.
We can see that the volume of the Lopez's refrigerator is obtained by adding 16 cubic inches to the volume of the Hawk's refrigerator.
Since 16 cubic inches are being added to the Hawk's refrigerator to get the Lopez's refrigerator, the volume of the Hawk's refrigerator must be 16 cubic inches less than the volume of the Lopez's refrigerator.
So, option D, "The volume of the Hawk's refrigerator is 16 cubic inches less than the volume of the Lopez's refrigerator," is the correct statement.

The box-and-whisker plot represents the heights (in meters) of the tallest buildings in Chicago.
a. What percent of the buildings are no taller than 345 meters?
About ____
percent of the buildings are no taller than 345 meters.
Answer:
75%
Step-by-step explanation:
The answer is 75% because each point/dot, represents 25% of the data. Below 345 meters are 3 points, therefore 3 * 25% = 75%.
Approximately 75% of the buildings are no taller than 345 meters for the box-and-whisker plot.
What is the box and whisker plot?A box and whisker plot (also known as a box plot) depicts a five-number summary of a set of data: lowest, lower quartile, median, upper quartile, and maximum.
The box-and-whisker plot represents the heights (in meters) of the tallest buildings in Chicago.
We can see that all three of the data points that are less than or equal to 345 meters are included in the lower half of the box-and-whisker plot, which represents the range from the minimum to the median height.
This means 3 × 25% = 75%.
So, we can estimate that approximately 50% of the buildings are no taller than 345 meters.

Answer:
The answer is "[tex]r=0.175 \ ft[/tex]"
Step-by-step explanation:
using formula:
[tex]\to \text{profit = revenue-cost}[/tex]
[tex]\to revenue = 70 \times 4\pi r^2 = 280\pi r^2\\\\\to cost = 800 \times \frac{4}{3} \pi r^3 = \frac{3200}{3} \pi r^3[/tex]
so,
[tex]\to profit (p)= 280\pi r^2 - \frac{3200}{3} \pi r^3\\\\\text{max profit when}\\\\\to 560 \pi r-3200 \pi r^2=0[/tex]
[tex]\to \pi r(560 -3200r)=0\\\\ \to (560 -3200r)=0\\\\\to 3200r=560\\\\\to r=\frac{560}{3200}\\\\\to r=\frac{56}{320}\\\\\to r=\frac{7}{40}\\\\\to r=0.175 \ ft[/tex]

Answer:
C
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (- 5, 3 ) and r = 4 , then
(x - (- 5))² + (y - 3)² = 4² , that is
(x + 5)² + (y - 3)² = 16 → D
The exponential function), whose graph is given below, can be written as h(x) = a•b^x.
Complete the equation for h(x).
Answer:
Step-by-step explanation:
h(x)=a*b^x
it passes through (0,6) and (1,4)
6=a*b^0
6=a*1
a=6
h(x)=6*b^x
