The perimeter of a rectangle is 92 cm. If the length is 22 cm, how wide is the rectangle?
A) First write an equation you can use to answer this question. Use w as your variable in the equation.
Answer:
W = 24cm
Step-by-step explanation:
p of a rectangle = 92
L = 22cm and W = ?
p = 2(L+W)
92 = 2(22+W)
92 = 44 + 2W
2W = 92 - 44
2W = 48
W = 48/2
W = 24cm
A triangle with a perimeter of 30 inches has sides of x+3, 2x+5, and x. find the value of x
Answer:
x = 5.5 inches.
Step-by-step explanation:
The perimeter is the sum of the 3 sides, so:-
x + x + 3 + 2x + 5 = 30
4x + 8 = 30
4x = 22
x = 5.5.
A bag is filled with green and blue marbles. There are 41 marbles in the bag. If there are 15 more green marbles than blue marbles, find the number of green marbles and the number of blue marbles in the bag.
Find the solution by setting up an equation. You have two choices for how you will pick your variable. For each of the following variable choices, write an equation (just set up the equation, do not solve it yet) that describes the relationship between the number of green marbles, the number of blue marbles, and the total number of marbles in the bag:
there will be 26 blue marbles
Step-by-step explanation:
41-15=26

Triangle ABC has coordinates A(-4,1), B(0,-2),and C(4,1).
The perimeter of ∆ABC is ___ units.
9514 1404 393
Answer:
18 units
Step-by-step explanation:
The distance formula is used to find the distance between two points:
d = √((x2 -x1)² +(y2 -y1)²)
For AB, the distance is ...
d = √((0 -(-4))² +(-2 -1)²) = √(16 +9) = √25 = 5
The distances between the other pairs of points can be found the same way. We have elected to let a spreadsheet do the math. It tells us the perimeter of triangle ABC is 18 units.
Answer: 18 units

23 + 3.54 ÷ 3 − 1.089
Answer:

Step-by-step explanation:
Always divide first then continue with subtraction then addition.
Hey there!
Just do PEMDAS
Parentheses

Subtraction
23 + 3.54 / 3 - 1.089
= 23 + 3.54 / 3 - 1.089
3.54 / 3 = 1.18
= 23 + 1.18 - 1.089
23 + 1.18 = 24.18
= 24.18 - 1.089
= 23.091
Answer: 23.091

a circle has a radius of 4m. find the circumference of the circle show your worth and strictly answering used 3.14 for pi
Answer:
25.12
Step-by-step explanation:
Circumference (C) = 2πr
Where r = radius
We want to find the circumference of a circle with a radius of 4m ( this means that r = 4 )
To do so we simply plug in the value of r into the circumference formula
Formula: C = 2πr
r = 4 ( note that it says use 3.14 for π )
plug in values
C = 2(3.14)(4)
Simplify
C = 25.12

Answer: Choice B
[tex]\frac{1}{\sqrt{65}}<-4, 7>[/tex]
===============================================================
Explanation:
Consider a right triangle with legs a = 4 and b = 7. Through the pythagorean theorem, the hypotenuse is
c = sqrt(a^2+b^2) = sqrt(4^2+7^2) = sqrt(65)
This represents the length of the vector <-4,7>
Dividing each component by the length will normalize the vector. This is the same as multiplying by [tex]\frac{1}{\sqrt{65}}[/tex] which is what choice B shows. The phrasing "normalize the vector" means "make the vector to be of length 1". A common application of normalizing vectors will come up in computer graphics.
The original vector and the vector mentioned in choice B point in the same direction. The only thing that has changed is the length from sqrt(65) to 1.

first you do 12 times 8 which equals to 96 then you add 9 to it which equals 105 hours
Answer:
105
Step-by-step explanation:
12 days x 8 hours = 96 hours
96 hours + 9 additional hours = 105.

In the last year,a total of 14,905 earthquakes occurred in a country. Of these,88.8% were minor tremors with magnitude of 4.9 or less on the Richter scale. How many minor earthquakes occurred in the country in the last year?
Answer:
13,236 minor earthquakes occurred
Step-by-step explanation:
[tex]\frac{Part}{Total}[/tex]
"x" part amount of earthquakes
14,905 total amount of earthquakes
88.8 % part percentage of earthquakes
100% total percentage of earthquakes
[tex]\frac{x}{14905}[/tex] = [tex]\frac{88.8}{100}[/tex]
x = 14,905 × [tex]\frac{88.8}{100}[/tex]
x = 14,905 × 0.888 = 13,235.64 ≈ 13,236 minor earthquakes occurred
PLEASE HELP!!! How does the multiplicity of a zero affect the graph of the polynomial function?
9514 1404 393
Answer:
2, 4, 61crossStep-by-step explanation:
Consider a zero at x=1.
If it has multiplicity 1, the corresponding factor is (x -1). Now consider the sign of that factor for x = 1.1. The value is (1.1 -1) = 0.1, a positive number.
When the value of x is 0.9, the factor is (0.9 -1) = -0.1, a negative number.
This tells you that values to the left of a zero make the factor(s) associated with that zero be negative. For x-values to the right of the zero, the factor(s) will be positive.
If the multiplicity is even, the product of those factors is positive on either side of the zero. (A negative number to an even power is a positive number.) That is, the graph will not change sign from one side of an even-multiplicity factor to the other. At an odd-multiplicity factor, the graph changes sign.
__
For the problem at hand, the only even-multiplicity factor is (x -1), so the graph will not change sign at x=1. It will touch the axis (be tangent to the x-axis), but will not cross. The other zeros have odd multiplicity (1 or 3), so the graph will change sign there.
It is worthwhile to note that the higher the multiplicity, the "flatter" the graph is at the zero. You can see this in the attachment by comparing the shape of the graph at x=6 with the shape at x=2 (also an upward zero crossing).
_____
Additional comment
You may wonder why the curve is below the x-axis at x=1 when the product of the factors in that neighborhood is always positive. The reason is that there are an odd number of zeros to the right of x=1, so the product of those factors is negative.

Josef has $300 to spend. Which inequality could help him find the maximum number of gifts, x, he could buy if he needs $215 to fix his car and then wants to spend $15 on each gift?
Answer:
x = (300 - 215)/15
Step-by-step explanation:
x, the amount of gifts, is equal to the amount of money left over after he fixes his car, divided by the amount he's willing to spend on each gift.
josef could buy a maximum of 5 gifts! the answer is 5.6 but he can't buy half a gift, nor can he afford 6, so we round down to get 5 gifts :)
Answer:
Josef can buy 5 gifts for 75$

Please help me and thank you!! Show the steps also please I got 198x
9514 1404 393
Answer:
264x³-66x
Step-by-step explanation:
The order of operations requires this be evaluated as ...
11x(96x÷4x -6) . . . . given
11x(24x·x -6) . . . . . . division inside parentheses
11x(24x² -6) . . . . . . multiplication inside parentheses
264x³ -66x . . . . . multiply by outside factor (use the distributive property)
_____
Additional comment
The appearance of the expression in parentheses may induce you to evaluate it as (96x)÷(4x) = 24. The order of operations requires that you do the division before the multiplication, left to right, so this must be evaluated as ...
((96x)÷4)x = 24x²
You need to be very careful with division and with exponents to make sure to follow the Order of Operations exactly. If you have an appropriate calculator, it will do that automatically. For example, if you tell your calculator ...
(for x=2) 11×2×(96×2÷4×2-6)
it should give you the result 1980, not 396.
Answer:
= 198x
Step-by-step explanation:
11x × { 96x ÷ 4x -6}
11x × { 24x -6}
264x - 66x
= 198x
You got the correct answer
