Answer:
1. 2/21
2. 7/45
3. 9/26
4. 4/61
5. 3/29
6. 8/61
Step-by-step explanation:
I'll just explain number one, since you can do the same thing to solve all the others.
You start with 10 1/2. You can make this an improper fraction by multiplying 10 and 2, then adding one. This leaves you with 21/2. The reciprocal of a fraction is just the numerator and denominator of the fraction flipped. So, you get 2/21.
Hope this helps!
9. Suppose the perimeter of a triangle is given by
P = 13x + 5y, and two of its sides have lengths of
2x + y and 8x + 4y. What is the length of the third
side?
Answer:
The length of the third side is 3x
Step-by-step explanation:
Algebraic Expressions
This problem deals with the ability to manage algebraic expressions in two variables.
Recall the perimeter of a triangle is the sum of its three sides. We already know the perimeter of the triangle is:
P=13x+5y
We also know the lengths of two of its sides are 2x+y and 8x+4y. The sum of those sides is:
S2=2x+y+8x+4y
Joining like terms:
S2=10x+5y
The third side must be the difference between the perimeter and the sum above:
S3=13x+5y-(10x+5y)
Operating:
S3=13x+5y-10x-5y
Joining like terms:
S3=3x
The length of the third side is 3x

Solve for d.

d =
Answer:
4
Step-by-step explanation:
4d + 1 = 17
1 + 4d = 17
Move all terms containing d to the left, all other terms to the right.
1 + -1 + 4d = 17 + -1
0 + 4d = 17 + -1
4d = 17 + -1
4d = 16
d = 4
Given f(x) = x2 – 2x, what is f(-6)?
The Acme Company manufactures widgets. The distribution of widget weights is bell-shaped. The widget weights have a mean of 37 ounces and a standard deviation of 7 ounces. Use the Empirical Rule, also known as the 68-95-99.7 Rule. Do not use Tables or Technology to avoid rounding errors. Suggestion: sketch the distribution in order to answer these questions. a) 68% of the widget weights lie between and b) What percentage of the widget weights lie between 23 and 44 ounces
Answer:
a) 68 % will lie between 30 and 44 ounces
b) between 23 and 44 ounces will lie 81,5 %
Step-by-step explanation: See Annex
a) Normal Distribution N ( 37, 7)
The Empirical Rule establishes that 68 % of values will be at
μ ± 1 σ where μ is the mean and σ the standard deviation
Then: 37 - 7 = 30 and 37 + 7 = 44
68 % of the values will lie between 30 and 44 ounces
b) And between 23 and 44 we should find:
We have 95 % of values between
μ ± 2*σ
In our case to the left of the value (mean 0 ) and up to the value 23 we get 95/2 = 47,5 % and to the right of the value (mean 0 ) and up to 44 we half 68/2 = 34 %
Then between 23 and 44, we have 47,5 + 34 = 81,5 %
Find the number such that the sum of that number and 25 is 48
Answer:
x = 23
Step-by-step explanation:
x + 25 = 48
x = 23....
Answer:
23
Step-by-step explanation:
You subtract 25 from 48
48 - 25 = 23

y = −4x
16x + 4y = 9
4x + 2y = 3
y = −4x + 15

Please I need help!! I will give Brainerly to whoever gets it right!
Answer:
Options 1 and 4 are the only other parallel lines
Step-by-step explanation:
Plug the equation into a graphing calculator and observe your results.
Answer:
The answers are y = −4x, 16x + 4y = 9, and y = −4x + 15
Step-by-step explanation:
y=-4x has the -4 as slope so it parallel
y = −4x + 15 also has the -4 as a slope so it parallel
16x + 4y = 9 u have to solve.
4y=-16x+9 First step is to subtract -16 both sides (which just tosses -16 to the other side where the 9 is.
y=-4x+2.25 Divide everything by 4

What is the midpoint of 50 and 49
The Midpoint between 50 and 49 is 49.5
What is Midpoint?The exact middle point between two numbers is referred to as the midpoint. By adding the two numbers together and then dividing the result by two, we can determine the midway of the two supplied values. It is the two numbers' average.
Given:
First number= 50
and second number= 49
So, the Midpoint between 50 and 49
= First number + second number/2
= 50+ 49 / 2
= 49.5

Write the standard form of the equation of the circle with radius 7 and center (4,−9).
Answer:
x^2 + y^2 - 8x + 18y + 48 = 0
Step-by-step explanation:
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the centre of circle and r is the radius of circle. hence the standard form of equation can be obtained by expanding
(x-4)^2 + {y-(-9)}^2 = 7^2
