Last month I had 8 guppies. This month I have 20 guppies. What is the percent of increase in guppies from last month to this month?
Answer: 150% increase
Step-by-step explanation:
percent of increase: new/old × 100%-100%
--------------
new/this month: 20 puppies
old/last month: 8 puppies
new/old×100%-100%
=20/8×100%-100%
=2.5×100%-100%
=250% -100%
=150% increase
Hope this helps!! :)

Find an equation in standard form for a parabolic function that goes through the points (1,-12) (3,16) and has a stretch factor of 2
Answer:
Vertex form of a quadratic equation is y=a(x-h)2+k, where (h,k) is the vertex of the parabola.
The vertex of a parabola is the point at the top or bottom of the parabola.
'h' is -6, the first coordinate in the vertex.
'k' is -4, the second coordinate in the vertex.
'x' is -2, the first coordinate in the other point.

i need step by step explanation for thisss >33
Answer:
Step-by-step explanation:
The question says find the number eight times of a certain two digit number exceeding the number 19.The tens digit than the units digit . So,you have to multiply eight to a two digit number exceeding 19 so you find a number exceeding 19 which would have to be able to to multiply by eight to exceed the number 19
find the number eight times of a two digit number higher than the number nineteen. The tens digit than the units digit .you have to multiply 8 to a 2 digit number exceeding nineteen so you find a number exceeding ninteen which would have to be able to to times by 8 to go higher than the number nineteen

The length of a rectangle is 3ft more than twice the width, and the area of the rectangle is 54ft^2. Find the dimensions of the rectangle.
Answer: Let length = 2x + 3
Let width = x
Area = 54 ft2
length × width = Area
x(2x + 3) = 54
2x2 + 3x = 54
2x2 + 3x - 54 = 0
(2x - 9)(x + 6) = 0
x = 9/2 and x = -6
x = 4.5 and x = -6
We accept x = 4.5 because length cannot be a negative value. Substituting this value into the dimensions:
width = 4.5 ft
length = 2(4.5) + 3 = 9 + 3 = 12 ft

Two third of a number is greater than one third of the number by 5. The number is ________
Let's assume the number as x
→ ⅔rd of x =( ⅔)x
Now ⅔ of x is greater than ⅓ of 5 .
[tex] \sf{ \implies \: \dfrac{1}{3} \times 5 = \dfrac{5}{3} } [/tex]
[tex]\sf{ \implies \: \dfrac{2}{3} \times x > \dfrac{5}{3} } [/tex]
[tex]\sf{ \implies \: x > \dfrac{5}{3} \times \dfrac{3}{2} }[/tex]
[tex]\sf{ \implies \: x > \dfrac{5}{2} }[/tex]
So number will be greater than 5/2 .

The surface area of a cube is 600 cubic centimeters. What is the volume? Answer Choices are on the Image.
Answer:
D. 1,000 cm^3
Step-by-step explanation:
Surface area of a cube is calculated by multiplying the square value of the edge by 6 which is shown as 6 × a^2
6 × a^2 = 600
a^2 = 100
a = 10
The volume of a cube is calculated by multiplying edge with itself three times which is shown as a^3
10^3 = 1000
Answer:
D
Step-by-step explanation:
10×10 on each side of the cube= 100. 6 sides = 600.
10×10×10= 1000

The Bradenton Post polled 1,356 adults in the city to determine whether they wet their toothbrush before they put toothpaste on it. Of the respondents, 54% said they wet it first. Suppose 68% of all adults actually wet their toothbrush first. What are the mean and standard deviation of the sampling distribution?
Answer:
deviation = -95.50147493 mean = 61
Step-by-step explanation:
54% wet there brushes first
suppose 68% wet there brushes what is the mean
mean: a mean is where you add both numbers together to get a total then divide by how many numbers you added for now we wont need the amount of people we just need the percentages for this
54 + 68 = 122
we added to numbers so well divide by 2
122 divided by 2 or 122/2 is equal to 61
61 is our mean
standard deviation : this is were you take the known average 1356 adults and subtract the mean
1356- 61 = 1295 then divide by 1356 and times by 100
if the number is positive then the mean is higher than expected but luckily its a negative so its -95.50147493
Right triangle XYZ, with vertex Y at (-3, 0), is rotated clockwise 180° about the origin. Which of the following rotations is equivalent to 180° clockwise rotation about the origin? clockwise 360° counterclockwise 180° counterclockwise 360° clockwise 270°
Answer:
the rule for rotation 180 degrees clockwise around the origin is:
(x,y) --------> (-x,-y)
(-3,0) --------> (-(-3),0)
(-3,0) --------> (3,0)
rotation counterclockwise 180 degrees is the same as rotation 180 degrees clock wise:
(x,y) -------->(-x,-y)
Answer:
the answer is counterclockwise 180

The equations of three lines are given below. Line 1: 6x-4y=6 Line 2: -2y=3x+5 Line 3: y=-2/3x+7 For each pair of lines, determine whether they are parallel, perpendicular, or neither.
Answer:
Line 1 and Line 2: Neither -- slopes are not same (one is negative one is positive)
Line 1 and Line 3: Perpendicular -- Line 3's slope is the negative reciprocal of Line 1's
Line 2 and Line 3: Neither -- different slopes
Step-by-step explanation:
Lines are parallel if they have the same slope but different y-intercept.
Lines are perpendicular if the slopes are negative reciprocals.
