Answer:
ten times I hope I'm right
Step-by-step explanation:
3 × 100 = 300
3 × 10 = 30
sense 3 is what is being talked about, 3 in the 300 is 100 times and 3 in 30 is 10 times.
100 is 10 times 10
10 × 10 = 100
value is the total
how many times greater is the total of the 3 in both numbers
3 in 300 is 10 times the 3 in 30
hope this helps
Bella and Justin went to the bank to open new checking accounts. The equation C=0.1n+1.50 represents the monthly cost, C, in dollars, where n is the number of checks written by Bella. In Justin’s account, the monthly cost is proportional to the number of checks written. The monthly cost for Justin’s account is $1.20 for writing 3 checks. How many checks must Bella and Justin write, if any, so that the cost of the accounts is the same for one month? What is the cost, if any?
If Bella and Justin write
checks, it will cost them both $
for one month.
The cost would be the same for Justin and Bella if 500 checks are sold, costing about $200.
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
Given the equation for Bella:
c = 0.1n + 150
Where C is the monthly cost for n checks.
For Justin:
1.2 = 3k
k = 0.4
C = 0.4n
To have the same cost:
0.1n + 150 = 0.4n
n = 500
c = 0.4(500) = 200
The cost would be the same for Justin and Bella if 500 checks are sold, costing about $200.

Kristen is paid $8.25 per hour. how much would her paycheck be for 39 hours? show your work.
Answer:
$321.71
Step-by-step explanation:
To do this problem, we have to multiply 8.25 by 39 because Kristen gets paid $8.25 per hour, and she worked for 39 hours. Here is my work below:
[tex]8.25 X 39=321.71[/tex]
So, Kristen gets paid $321.71 for working 39 hours.

What is the circumference of 7 in?
Answer:
If Its 7 in diameter than the answer is 21.98 if it is radius than it is 153.86
Step-by-step explanation:
Answer:
Solution:
Radius of a circle = 7 in
We know that
Circumference of a circle = 2πrSubstituting the values
= 2 × π × 7
= 14π

A cube has an edge length of 3 inches.
a) Find the surface area and volume of the cube.
b) The cube is dilated by a scale factor of 0.5.
Find the surface area and volume of the image.
PLEASE HELP THIS IS DUE TOMORROW!!!
Answer:
Question (a)
Surface area of a cube = [tex]6x^2[/tex] (where [tex]x[/tex] is an edge length)
⇒ surface area = 6 × 3²
= 6 × 3 × 3
= 6 × 9
= 54 in²
Volume of a cube = [tex]x^3[/tex] (where [tex]x[/tex] is an edge length)
⇒ volume = 3³
= 3 × 3 × 3
= 27 in³
Question (b)
To find the area of a dilated figure, simply multiply the original area by the scale factor squared:
Surface area = [tex]6x^2[/tex] × sf²
= 54 × 0.5²
= 13.5 in²
To find the volume of a dilated figure, simply multiply the original volume by the scale factor cubed:
Surface area = [tex]x^3[/tex] × sf³
= 27 × 0.5³
= 3.375 in³

An angle measures 64° less than the measure of its supplementary angle what is the measure of each angle
Given :
An angle which measures less 64° the measure of its supplementary angle.⠀
To Find :
The measure of its supplementary angle.⠀
Solution :
Let's assume the one of the supplementary angle as x and the other angle as (x - 64)° .Now,
⠀
According to the Question :
[tex]\longrightarrow\qquad \sf{{x
+ (x - 64) {}^{ \circ} = {180}^{ \circ} }}[/tex]
[tex]\longrightarrow\qquad \sf{{x + x - 64 {}^{ \circ} = {180}^{ \circ} }}[/tex]
[tex]\longrightarrow\qquad \sf{{2x - 64 {}^{ \circ} = {180}^{ \circ} }}[/tex]
[tex]\longrightarrow\qquad \sf{{2x = {180}^{ \circ} + 64 {}^{ \circ}}}[/tex]
[tex]\longrightarrow\qquad \sf{{2x = {244}^{ \circ} }}[/tex]
[tex]\longrightarrow\qquad \sf{{x = \dfrac{{244}^{ \circ}}{2} }}[/tex]
[tex]\longrightarrow\qquad \mathfrak{\pmb{{x = {122}^{ \circ} }}}[/tex]
⠀
Therefore,
One angle = 122°Other angle = 122° – 64° = 58°⠀
⠀
Henceforth ,
The measure of the two angles are 122° and 58° .Select the correct solutions for the system of equations:

eric sells donuts for $7 per dozen. which equation can be used to determine the total cost, t, for x dozen of donuts?
Answer:
7 times x = t
Step-by-step explanation:
if your buying 3 dozen of donuts, the total cost would be by doing 7x3
Solution:
It should be noted:
Given sentence: Eric sells donuts for $7 per dozen.Let's reread the sentence carefully.
Eric sells donuts for $7 per dozen.
↥ ↥
$7 1 dozen
The equation created: $7 = 1 dozen
If x dozen doughnuts were sold, equation: $7x = t = x dozen
Thus, the equation that can determine the total cost, t, for x dozen of donuts is $7x = t.

Which of the following are among the basic postulates of Euclidean Geometry?
A) Any straight line segment can be extended indefinitely.
B) All right triangles are equal.
C) A straight line segment can be drawn between any two points.
D) All right angles are equal.
Any straight line segment can be extended indefinitely and straight line segment can be drawn between any two points can apply. Therefore, options A and D are the correct answers.
What is Euclidean geometry?"Euclidean geometry is the study of plane and solid figures on the basis of axioms and theorems employed by the Greek mathematician Euclid"
As per the five basic postulates of Euclidean geometry
A straight line can be drawn from any point to another point.
A terminated line can be further produced indefinitely.
A circle can be drawn with any Centre and any radius.
All right angles are equal to one another.
If two lines are drawn which intersect a third in such a way that the sum of the inner angles on one side is less than two right angles , then the two lines inevitably must intersect each other on that side if extended far enough.
Therefore, options A and D are the correct answers.

Step-by-step explanation:
when you add all the numbers together you get 14, also where you put the line you can see that the line is a 3 and 5 minus 2 is 3. The next corner next to the 3 is 1 cm because if you look at the horizontal 2 it matches up with the horizontal 1 and 2 minus 1 is 1.
The height of a rocket t seconds after launch is modeled by the function: f(t)=-16t^2+72t.
What is the maximum height of the rocket in feet?
Step-by-step explanation:
the extreme values of a function happen at the zeros of the first derivation of that function.
f(t) = -16t² + 72t
f'(t) = -2×16t + 72 = -32t + 72
0 = -32t + 72
32t = 72
t = 72/32 = 2.25 seconds
f(2.25) = -16(2.25)² + 72×2.25 = -16×5.0625 + 72×2.25 =
= -81 + 162 = 81 ft
so, the rocket reaches its maximum height of 81 ft after 2.25 seconds of flight.
