Answer:
180 in2
Step-by-step explanation:
surface areas of similar solids are proportional to the square of their corresponding sides
area of larger/90 = 10^2/5^2
area of larger = 90(100/25) = 180 in^2
Answer:
surface areas of similar solids are proportional to the square of their corresponding sides
area of larger/90 = 10^2/5^2
area of larger = 90(100/25) = 360 in^2
Please solve this for me.
Answer:
x = 14
Step-by-step explanation:
Figure A to Figure B = 1:3.5 = 1/3.5
Therefore:
Side length of figure A to side length of figure B = 1/3.5
Thus:
4/x = 1/3.5
Cross multiply
x*1 = 3.5*4
x = 14

The point (0, 0) does not lie on the step function given by y = 4x + 2
What is a step function?
A step function can be represented by a linear function.
Let y represent the cost of charging the electric car for x hours, hence:
Station A is $2 to start and $4 for each hour or fraction of an hour:
y = 4x + 2
The point (0, 0) does not lie on the step function given by y = 4x + 2

What is the value of x in the equation 2x - 3/5 = -1/10
Answer:
1/4
Step-by-step explanation:
you add 3/5 to the other side and find the lcm making it 6/10--1/10=5/10. Then 5/10 divided by 2 = 2.5/10 which you can simplify to 1/4.
Answer: x=1/4
Step-by-step explanation:
1. Isolate x: if you move -3/5 to the other side, your equation would become
=> 2x=-1/10+3/5
2. Find the common denominator: since you can't add -1/10 with 3/5 without simplifying, you're equation would change to this:
=> 2x=-1/10+6/10
3. Simplify:
=> 2x=5/10 => 2x=1/2
4. Divide:
=> 2x=1/2 => x=1/2*1/2 => x=1/4

Which statement about the properties of Function A and Function B are true?
Select each correct statement.
A The Y-intercept of Function A is equal to the Y-intercept of Function B.
B The Y-intercept of Function A is less than the Y-intercept of Function B.
The Y-intercept of Function A is greater than the Y-intercept of Function B.
D The rate of change of Function A is equal to the rate of change of Function B.
E The rate of change of Function A is less than the rate of change of Function B.
Answer:
B. The Y-intercept of Function A is less than the Y-intercept of Function B
F. The rate of change of Function A is greater than the rate of change of Function B
Step-by-step explanation:
Function A rate of change and y-intercept:
✔️Rate of change using two pairs of values from the given table, (1, 2) and (3, 10):
Rate of change = ∆y/∆x = (10 - 2) / (3 - 1) = 8/2 = 4
Rate of change (m) of Function A = 4
✔️ To find the y-intercept (b) of function A, substitute (x, y) = (1, 2) and m = 4 into y = mx + b (slope-intercept form):
2 = 4(1) + b
2 = 4 + b
2 - 4 = b
-2 = b
b = -2
Y-intercept (b) of function A = -2
Function B rate of change (m) and y-intercept (b):
The function, y = 3x + 4 is given in the slope-intercept form, y = mx + b.
Therefore,
Rate of change/slope (m) = 3
Y-intercept (b) = 4
The following staments about the properties of both functions are therefore true:
B. The Y-intercept of Function A is less than the Y-intercept of Function B
F. The rate of change of Function A is greater than the rate of change of Function B

Use the Law of Sines to determine the length of
side c.
44°
B
29
49
34
21
Answer:
c = 29
Step-by-step explanation:
Law of sines is given as: [tex] \frac{a}{sin(A)} = \frac{b}{sin(B)} = \frac{c}{sin(C)} [/tex]
B = 180 - (57 + 44) = 79°
b = 41
C = 44°
c = ?
Thus:
[tex] \frac{b}{sin(B)} = \frac{c}{sin(C)} [/tex]
Substitute
[tex] \frac{41}{sin(79)} = \frac{c}{sin(44)} [/tex]
Multiply both sides by sin 44
[tex] \frac{41}{sin(79)}*sin(44) = \frac{c}{sin(44)}*sin(44) [/tex]
[tex] \frac{41*sin(44)}{sin(79)}*sin(44) = c [/tex]
c = 29.0140633 ≈ 29

A box of jerseys for a pick-up game of basketball contains 10 extra-large jerseys, 6 large jerseys, and 4 medium Jerseys. If you are first to the box and grab 2 jerseys, what is the probability that you randomly grab 2 medium jerseys? Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.
Answer: 3/95
Total Number of jerseys:
10+6+4=20
Odds of first jersey being medium:
4/20
Odds of second jersey being medium
3/19
(4/20)*(3/19)=12/380=
6/190=3/95
The probability that you randomly grab 2 medium jerseys is 3.15%.
Since a box of jerseys for a pick-up game of basketball contains 10 extra-large jerseys, 6 large jerseys, and 4 medium Jerseys, to determine, if you are first to the box and grab 2 jerseys, what is the probability that you randomly grab 2 medium jerseys, the following calculation must be performed:
10 + 6 + 4 = 20 4/20 x 3/19 = X 0.0315 = X 0.0315 x 100 = 3.15%
Therefore, the probability that you randomly grab 2 medium jerseys is 3.15%.

Answer:
Radius.
Step-by-step explanation:
A line joining the center of a circle to a point on the circle is called a radius.
This ultimately implies that, it is the straight line from the center of a circle to any point on the edge of the circle. Also, radius is half of a diameter i.e diameter divided by the 2.
Generally, the radius is used for calculating the area and circumference of a circle.
Area of a circle = πr²
Circumference of a circle = 2πr
The S.I units for measuring radius is meters.

Answer:
110º
Step-by-step explanation:
Because the angle starts at 10º, and ends at 120º, so if we moved the angle down to start at 0º we would have to subtract 10º, so we must subtract 10º from 120º. You end up with 110º.

Answer:
$70Step-by-step explanation:
ExplanationIf we reverse it we can break it down easier: We start at $935
15 dollars on every purchase, he sold 11 TVs. So we find the total amount of money, 15*11=165
935-165=770
770 is the amount left without the money he has earned so the total base.
770/11=70
Checking answerLet's rebuild it to test if it is correct...
$70 for each tv * 11 tv's = $770 or the base price of the tv's
$15 for all the warranties
$15*11=165
165+770=935
So the answer is 70$
Hopefully, this helped.
Have a great day.
