find the two values that x can have if x2-12=37
Answer:
[tex]x2 - 12 = 37[/tex]
Step-by-step explanation:
Add 12 to both sides:
[tex]x2 - 12 + 12 = 37 + 12[/tex]
Simpilfy:
[tex]x2 = 49[/tex]
Simplify:
[tex]2x^{2} = 49[/tex]
Simplify:
[tex]\frac{2x^{2} }{2} = \frac{49}{2}[/tex]
[tex]x^{2} = \frac{49}{2}[/tex]
For x^2 = f(a) the solutions are x = [tex]\sqrt{f(a)} , - \sqrt{f(a)}[/tex]
x = [tex]\sqrt{\frac{49}{2} } , x = -\sqrt{\frac{49}{2} }[/tex]

Jody has a plastic container in the shape of a rectangular prism. The container is 8 1/2 inches long, 4 inches wide, and 3 1/2 inches high. What is the volume of this plastic container?
Answer:
=119 in ^3
Step-by-step explanation:
The volume of a rectangle prism is given by
V = l*w*h
Changing to decimal form
= 8 .5 * 4 * 3.5
=119 in ^3
Answer: 119^3
Step-by-step explanation:
To find out the volume of a rectangular prism you have to multiply length x width x height.
8.5 x 4 = 34
34 x 3.5 = 119^3
A basketball team wants to paint half of a free-throw circle grey. If the radius of the free-throw circle is 5.4 feet, what is the area that will be painted grey? Use 3.14 for , and round to the nearest square foot.
Answer:
The area which would be painted grey will be "47.7812 ft²".
Step-by-step explanation:
The given values are:
Radius of circle, r = 5.4 feet
Value of pi, π = 3.14
As we know,
Area of Semicircle = [tex]\frac{\pi r^2}{2}[/tex]
On putting the values in the above formula, we get
= [tex]\frac{3.14\times (5.4)^{2}}{2}[/tex]
= [tex]\frac{3.14\times 29.26}{2}[/tex]
= [tex]\frac{91.5624}{2}[/tex]
= [tex]45.7812 \ ft^2[/tex]

The diagram shows a right-angled triangle and a parallelogram.
24 cm side of triangle
30 cm base of parallelogram
7cm base of triangle
The area of the parallelogram is 5 times the area of the triangle.
The perpendicular height of the parallelogram is hcm.
(b) Find the value of h.
Answer:
see explanation
Step-by-step explanation:
i know this is very late but ..
area of triangle= b*h/2
24*7/2=84
and it said the parallelogram is 5 times the area so we do
84*5=420 which is the total area of the parallelogram
now to find h we need to do
420/30=14
h=14 because 30*14=420
The required value of h is 14 cm for the given parallelogram.
What is Parallelogram?A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal.
The area of the triangle is (247)/2 = 84 square cm.
Since the area of the parallelogram is 5 times the area of the triangle, the area of the parallelogram is 845 = 420 square cm.
The area of the parallelogram is equal to the base (30 cm) multiplied by the height (h cm), so we can set up the equation:
30h = 420
To find the value of h, we can divide both sides of the equation by 30:
h = 420/30
h = 14 cm
Thus, the required value of h is 14 cm.

Determine the nth term formula for each of the following sequences and find the limit if it exists.
3, 3,-3, 3,
Answer:
aₙ = (-3) (-1)ⁿ⁻¹
limit does not exist
Step-by-step explanation:
-3, 3, -3, 3, ...
This is an alternating geometric series where the first term is -3 and the common ratio is -1. The nth term is therefore:
aₙ = (-3) (-1)ⁿ⁻¹
Since the sequence alternates between -3 and 3, the limit as n approaches infinity of aₙ does not exist.
On your birthday you receive a new TV valued at $1199. The value of the TV decreases by 25% each year. What will its value be 4 years from now?
Answer: 74.93
Step-by-step explanation: if you heard of the line equals line method this should be able to help you.
299.75 25%
---------------=------------------
$1199 100%
so you cross multiply 1199 and 25 and then divide it by 100. which would be 299.75 that is the price per 1 year then you divide that value by 4 and that will be your answer.
299.75 divided by 4= 74.93
hope this helps
Answer:
379.37
Step-by-step explanation:
I just did it the manual way
1199-25%=899.25
(25% of 1199 is 299.75)
899.25-25%=674.44
(25% of 899.25 is 224.81)
674.44-25%=505.83
(25% of 674.44 is 168.61)
505.83-25%= 379.37
(25% of 505.83 is 126.5)

The area of a rectangle is 256.5 square meters. If the length is 18 m, what is the perimeter of the rectangle?
Answer:
64.5 m
Step-by-step explanation:
1) Find the width: A = L*W, and so W = A / L = (256.5 m²) / (18 m) = 14.25 m.
2) Find the perimeter, using the formula P = 2L + 2W:
Here P = 2(14.25 m) + 2( 18 m) = 64.5 m
Which statement about liters and milliliters is true?
Answer:
Lesson Summary
A milliliter is a metric unit used to measure capacity that's equal to one-thousandth of a liter. Capacity is the amount of liquid a container can hold. One liter contains 1,000 milliliters, so to convert liters to milliliters you multiply the number of liters times 1,000.
Look at the equivalent metric units of capacity. When converting from a larger unit to a smaller unit, multiply by 1,000. When converting from a smaller unit to a larger unit, divide by 1,000. Liters are larger than milliliters, so multiply by 1,000.

Answer:
Its B. y-5x+5
Step-by-step explanation:
Use the slope formula
The equation of the linear model is y = 5x + 5. The correct answer is option B.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
We can find the equation of the linear model passing through two points using the slope-intercept form of a line:
y = mx + b
where m is the slope of the line and b is the y-intercept.
First, we need to find the slope of the line:
m = (y₂ - y₁) / (x₂ - x₁)
Let (0, 5) be the first point, and (3, 20) be the second point:
m = (20 - 5) / (3 - 0) = 15 / 3 = 5
Now that we know the slope, we can plug in one of the points and solve for the y-intercept:
y = mx + b
5 = 5(0) + b
b = 5
Hence, the equation of the linear model is:
y = 5x + 5

Step-by-step explanation:
A spinner with seven equal sized sections was used to play a game It was used 250 times in the first game Of those 250 the arrow landed on section 7 a total of 35 times The same spinner was used 150 times in the second game How many times did the spinner most likely land on section 7 in the second game A. 14 B. 21 C. 30 D. 35
Answer: 21
Step-by-step explanation:
From the question, a spinner with seven equal sized sections was used in playing a game. The spinner was used 250 times in the first game and the arrow landed on section 7 a total of 35 times. This can be expressed as:
= 35/250
= 0.14
The same spinner was also used 150 times in the second game. The number of times the spinner will most likely land on section 7 in the second game will be:
= 0.14 × 150
= 21
The spinner most likely land on section 7 in the second game for 21 times.

A set of measurements could be the side lengths of a triangle if and only if the sum of the lengths of any two sides is greater than the length of the remaining side (Triangle Inequality Theorem).
A)
3 cm, 3 cm, 3 cm - This is a valid triangle because the sum of any two sides is greater than the third side.
B)
4 cm, 8 cm, 13 cm - This is a valid triangle because 4+8 > 13, 4+13 > 8, and 8+13 > 4.
C)
5 cm, 9 cm, 14 cm - This is a valid triangle because 5+9 > 14, 5+14 > 9, and 9+14 > 5.
