Answer:
175%
Step-by-step explanation:
1. To find how much a percent of a number is, we'd just have to multiply the percent by the number. However, in this case, we're missing the percentage.
2. To find that percentage, we can write an equation of [tex]\frac{x}{100} * 4 = 7[/tex] because "of 4" means to multiply by 4, and "is 7" means that the product is 7.
3. Now, let's solve our equation.
[tex]\frac{x}{100} * 4 = 7[/tex]Step 1: Simplify both sides of the equation.
[tex]\frac{4}{100}x = 7[/tex] [tex]\frac{1}{25}x=7[/tex]Step 2: Multiply both sides by 25.
[tex]\frac{1}{25}x * 25 = 7 * 25[/tex] [tex]x = 175[/tex]Step 3: Check to see if solution is correct.
[tex]\frac{175}{100} * 4 = 7[/tex] [tex]\frac{700}{100} = 7[/tex] [tex]7 = 7[/tex]Therefore, the answer is 175%.

Compare and contrast pyramids and cones.
Be sure to use mathematical terms to describe parts of the solids.
a. In what ways are they alike?
b. In what ways are they different?
Choose either pyramids or cones, and explain how the formula for their volume can be described using other solids.
Answer:
Similarities: both have a base which extends into a single vertex.
Differences: a cone only has 1 edge and a pyramid has a minimum of 6 (for a triangular pyramid).
the base of a pyramid is a polygon - the base of a cone is a curve
(a mathematical cone has no edges at all it is a continuous sheet - or two sheets if you consider the vertex as dividing the surface into two sheets).
Step-by-step explanation:

The key difference between Pyramids and cones are:
A pyramid is basically a code that has a base in the form of a polygon.
Pyramids and cones are alike in the following ways:
Because a cone can be made from a right angle triangle, their formulas are also alike in some ways. Notice that both formulas are related to the height of the object.
The formula for the area of a right angle triangle is:
A = hb/2
The area of a cone is given as:

5 divided by 14?
......................................
Answer:
0.3571
Step-by-step explanation:
Step 1: Start by setting it up with the divisor 14 on the left side and the dividend 5 on the right side like this:
14[tex]\sqrt{x}[/tex]5
Step 2: The divisor (14) goes into the first digit of the dividend (5), 0 times(s).
Therefore, put 0 on top:
14[tex]\sqrt{x}[/tex]0 5
Step 3: Multiply the divisor by the result in the previous step (14 x 0 =0) and write that answer below the dividend.
14 0
[tex]\sqrt{x}[/tex]5
0
Step 4: Subtract the result in the previous step from the first digit of the dividend (5-0 = 5) and write the answer below.
14 0
[tex]\sqrt{x}[/tex] 5

I took a pic, I hope that's fine
Answer:
Well in order to find the y-intercept, the “x” has to be 0. To find that we need to find the pattern and to ind the pattern you would need to find the slope. The slope is -4 or 4/ -1
So the Y is 4 and the X is -1
So use that to add or subtract for the pattern
1, -4
0, 0
The y- Intercept is 0 or option (A)

Ice cream cones cost $1.10 and sundaes cost $2.35. One day, the receipts for a total of 172 cones and sundaes were $294.20. How many cones were sold.
Answer:88
Step-by-step explanation:
1.10c+2.35s=294.20
C+S=172
1.10c+2.35s=294.20 if you multiply by 100.
110c+235s=29420
-110 (cones + sundaes =172)
-110c-110s=-18920
125s/125=10500/125
S= 84
C+84=172
-84. -84
C= 88

Select the three ratios that represent the numbers of blue marbles to red marbles, there are 6 blue marbles and 9 red marbles
Answer:
6:9 or (2:3)
Step-by-step explanation:
A ratio is a term that gives comparison of values. It helps to determine
how much of a particular thing that is compare to other thing.
Given:
numbers of blue marbles= 6
numbers of red marbles= 9
Hence, ratios that represent the numbers of blue marbles to red = 6:9
We can reduce it using factor of 3, hence the ratio becomes(2:3)
Marco got 15 questions wrong on his 30-question test. What is his grade as a percent?
Answer:
15
Step-by-step explanation:
The grade percentage of Marco is 50%.
What is percentage?A percent is a dimensionless number, meaning that it has no units of measurement, since it represents a part of whatever whole is being measured.
Given that, Marco got 15 questions wrong on his 30-question test.
We need to find his grade as a percent,
So,
Since he got 15 answers wrong,
Therefore, his correct answers = 30-15.
That mean his grade in marks = 15
Now, his grade in percent = 15/30 x 100 = 50%
Hence the grade percentage of Marco is 50%.

Gina is building a rectangular prism out of sugar cubes for her art class project. She started by drawing a diagram of the rectangular prism that is 4 cubes high, 4 cubes long and 2 cubes wide. How many cubes does she use to make the prism?
The rectangular prism is made up of the dimensions
Lenght = 4 cubes
Width = 2 cubes
Height = 4 cubes
The total number of cubes she needs shall be derived as number of cubes along the lenght multiplied by number of cubes along the width, and then multiplied by number of cubes along the height. Therefore, she would have:
[tex]volume = l \times w \times h \\ volume \: = 4 \times 2 \times 4 \\ volume = 32 \: cubes[/tex]

f(3) = 12 for a geometric sequence that is defined
recursively by the formula f(n) = 0.5 ∙ f(n – 1), where
n is an integer and n > 0.
Write the equation in explicit form.
Answer:
[tex]f(n) = 96 * 0.5^n[/tex]
Step-by-step explanation:
Given
[tex]f(3) = 12[/tex]
[tex]f(n) = 0.5 * f(n-1)[/tex]
Required
Write as an explicit function
When n = 3, we have:
[tex]f(3) = 12[/tex]
[tex]f(3) = 0.5 * f(3-1)[/tex]
[tex]f(3) = 0.5 * f(2)[/tex]
Substitute: [tex]f(3) = 12[/tex]
[tex]12 = 0.5 * f(2)[/tex]
Solve for f(2)
[tex]f(2) = 12/0.5[/tex]
[tex]f(2) = 24[/tex]
So, we have;
[tex]f(3) = 12[/tex]
[tex]f(2) = 24[/tex]
Since it is a geometric sequence, calculate the common ratio (r)
[tex]r = \frac{f(3)}{f(2)}[/tex]
[tex]r = \frac{12}{24}[/tex]
[tex]r = 0.5[/tex]
Calculate the first term using:
[tex]r = \frac{f(2)}{f(1)}[/tex]
Solve for f(1)
[tex]f(1) = \frac{f(2)}{r}[/tex]
[tex]f(1) = \frac{24}{0.5}[/tex]
[tex]f(1) = 48[/tex]
The explicit function is then calculated as:
[tex]f(n) = f(1) * r^{n-1[/tex] ----nth term of a gp
[tex]f(n) = 48 * 0.5^{n-1[/tex]
Split the exponent
[tex]f(n) = 48 * \frac{0.5^n}{0.5^1}[/tex]
[tex]f(n) = 48 * \frac{0.5^n}{0.5}[/tex]
[tex]f(n) = 96 * 0.5^n[/tex]
What are the missing coordinates of the vertices of this rectangle?
Answer:
A ( -d , e )
B ( - d , -e )
C ( d , - e )
Step-by-step explanation:
The centroid of the circle is on the origin.
This means that coordinates are an equal distance away from each other
Ex. Coordinate A and coordinate B are an equal distance away.
The only difference between the coordinates is the signs of the x and y values
This is determined by what quadrant the specific coordinate is in
Ex. Coordinate A is in Quadrant 2.
Coordinates in Quadrant 2 have a negative x value and a positive x value
Because Coordinate A and the given coordinates ( d , e ) have an equal distance between them all we have to do to find the missing coordinate is add a negative sign in front of the x value (d)
That being said, the coordinate of A is (-d,e).
This process is used to find the rest of the missing coordinates
for B
B lies in Quadrant 3
Quadrant 3 = ( -x , -y )
* add negative signs to the x and y value of the given coordinate *
B = ( -d , - e)
For C
C lies in Quadrant 4
Quadrant 4 = ( x , - y )
* add a negative sign to the y value of the given coordinate *
C = ( d, -e)

Answer:
<ABT = 43°<TBC = 43°Step-by-step explanation:
Given,
Line BT is the bisector of <ABC
So,
3x + 13 = 5x - 7
=> 13 + 7 = 5x - 3x
=> 20 = 2x
[tex] = > x = \frac{20}{2} [/tex]
=> x = 10
As,
We got the value of x = 10
Therefore,
<ABT = 3x + 13 °
= 3×10 + 13 °
= 30 + 13°
= 43°
<TBC = 5x - 7°
= 5 × 10 - 7°
= 50 - 7°
= 43°
Hence,
Value of <ABT = 43° and value of <TBC = 43° (Ans)
What is the measure of ∠A, the exterior angle of the triangle shown below?
F. m∠A = 92°, because 180 – (50 + 38) = 92.
G. m∠A = 272°, because 180 – (50 + 38) = 92 and 92 + 180 = 272. H.m∠A=78°,because 50–38=12and90–12=78.
J. m∠A = 88°, because 50 + 38 = 88.
Answer: A is 88
Step-by-step explanation: Sum of all angles is 180 degree.
Let the third interior angle be x.
38+50+x=180
88+x=180
x= 92
A and X are in linear pair.
A+X=180
A+92=180
A=88
A circle is centered at the point (-7,-1) and passes through the point (8, 7). The radius of the circle is ___ units. The point (-15, __ ) lies on this circle
Answer:
(x + 7)2 + (y + 1)2 = r2.
To get we use point (8, 7): (8 + 7)2 + (7 + 1)2 = r2, r2 = 225 + 64 = 289 = 172.
So, equation of circle: (x + 7)2 + (y + 1)2 = 289

It doesn’t make sense. And Cookie Monster is sad that there are no cookies, and you are sad that you have no friends.” In this case, “Imagine that you have 14 cookies, and you split them evenly among zero friends. How many cookies does each person get? See? It doesn’t make sense. And Cookie Monster is happy he gets 14 cookies, and you are sad that you have no friends.”
