Students in Ms. Bell’s geometry class created posters of geometric definitions. Which of the following is the most precise definition?
A. Parallel lines are lines that do not intersect.
B. A line segment is part of a line that has an endpoint.
C. Perpendicular lines are lines that intersect at a right angle.
D. An angle is formed by two lines, two segments or two rays in one plane.
Answer:
C
Step-by-step explanation:
D is missing 2 ideas.
An angle can be formed by a mixture of the types of figures quoted.An angle has common or shared endpoint.B: to me is unclear. A line does not have an endpoint. A ray does.
A: you need to mention that the lines are coplanar.
I think, brief though it is, C is the most complete and at the same time simplest choice.
Jasmine bought 3500g of flour. She used 3/7 of it to bake some tarts and 700g of it to bake a cake. Find the ratio of the amount of flour used for baking the cake to the amount of flour used for baking the tarts to the remaining amount of flour.
Answer: 15:13
Step-by-step explanation: 7/7=3500
1/7=3500÷7=500500x3=15001500+700=22003500-2200=13001500:130015 : 13 (if there is a need to simplify the ratio)A water wheel has a radius of 18 feet. the wheel is rotating at 5 revolutions per minute. find the linear speed, in feet per minute, of the water
Answer:
The linear speed is
Step-by-step explanation:
step 1
Find the circumference of the circle
The circumference is equal to
we have
substitute
step 2
Find the linear speed in feet per minute
we know that
The wheel is rotating at 10 revolutions per minute
Convert revolutions to feet
Remember that
One revolution is equal to the circumference of the circle
so
10 revolutions is equal to
therefore
The linear speed is
There are 15 people expected for a dinner. If 3 ounces of corn serve 1 person and 1 can of corn is 9 ounces, how many cans of corn should be bought for the dinner?
Answer:
5 cans
Step-by-step explanation:
First multiply 15 by 3 to see how many ounces are needed in total: 15x3=45
Then divide 45 by 9 to see the amount of cans: 45/9=5
Three times the sum of a number and 2 is the same as three-fifths of the sum of the same
number and 22. What is the number?
Answer:
3
Step-by-step explanation:
3(n+2)=3/5(n+22)
3n+6=3/5n+66/5
3n-3/5n = 66/5 - 6
2.4n = 7.2
n = 7.2/2.4
n = 3
Two angles are supplementary. The measure of the larger angle is 36 more than the measure of the smaller angle. Find their measures.
the answers are 72° and 108° but I need help showing my work
x = smaller angle
x+36 = larger angle, since its 36 degrees more than the smaller angle
The two angles x and x+36 must add to 180 if they are to be supplementary (aka form a straight line)
So this means we can say the following:
(smaller)+(larger) = 180
(x) + (x+36) = 180
2x+36 = 180
2x = 180-36
2x = 144
x = 144/2
x = 72 is the smaller angle
x+36 = 72+36 = 108 is the larger angle
As a check:
smaller+larger = 72+108 = 180
which shows they are supplementary and it confirms our answers
Step-by-step explanation:
let the smaller angle be x
then the measure of larger angle will be x+36
x+x+36=180°(being supplementary angle)
2x+36=180°
2x=180°-36
2x=144°
x=144°/2
x=72°
now,
the larger angle x+36 = 72+36=108°

2- 7/8 (48x-8)+4=3(5x-19)
9514 1404 393
Answer:
infinite solutionsx = -2Step-by-step explanation:
1. The equation simplifies as follows:
5(x +2) =10 +5x
5x +10 = 5x +10 . . . . . eliminate parentheses, write in standard form
0 = 0 . . . . . . . . . . . . . . subtract 5x+10 from both sides
This is true for all values of x. Any value of x is a solution to this equation. There are an infinite number of solutions.
__
2. 7/8(48x -8) +4 = 3(5x -19) . . . . given
42x -7 +4 = 15x -57 . . . . . . . . eliminate parentheses
25x = -50 . . . . . . . . . . . . . add 7-15x to both sides
x = -2 . . . . . . . . . . . . . . divide by 25
Check
7/8(48(-2) -8) +4 = 3(5(-2) -19) . . . . substitute for x
7/8(-96 -8) +4 = 3(-10 -19)
7/8(-104) +4 = 3(-29)
-91 +4 = -87 . . . . . . . . . . true
Let A be a 4 x 5 matrix and Let B be a 4 x 4 matrix. Suppose you were asked to multiply matrix A times matrix B. When multiplied the resulting solution of multiplying matrix A times matrix B will be a 4x 4 matrix.
a. True
b. False
Answer:
b. false
Step-by-step explanation:
when multiplying matrixes the number of columns of the first matrix must be equal as the number of rows of the second matrix, and since here matrix A has 4 columns but matrix B has 5 rows they can't be multiplied

A student says that if 5x2 = 20, then x must be
equal to 2. Do
you agree or disagree with the
student? Justify your answer.
Answer:
I agree with the student's answer. "x" cannot be -2 because then it would make -20 which is not equal to 20:
5(-2)(2) = ?
-10 x 2 = ?
? = -20
-20 ≠ 20
Step-by-step explanation:
Justificaiton:
5(x)(2) = 20
10(x) = 20
10/10(x) = 20/10
x = 2
Second Justification:
5(x)(2) = 20
5/5(x)(2) = 20/5
2x = 4
2x/2 = 4/2
x = 2

Find the sum of the even numbers from 1 to 300
a) 14,280
b) 22,650
c) 16,100
d) 15,460
Answer:
The answer is 22,650
So, option b for you
Step-by-step explanation:
To find the sum of even numbers from 2 to 300, the formula we use is,
N ( N + 1 )
Where N is given by,
N = [( first number + last number)/2] - 1
So here, N = [ (2 + 300 ) / 2 ] - 1 = 150
And hence Sum = 150 * 151 = 22650
The pie chart below shows the Estrada family’s distribution of the monthly expenses for the last month. The Estrada family spent $366 on clothing last month.
What were the total expenses of the Estrada family last month?
Pie charts are used to show the relationship between data in a circle. The total expenses of the Estrada family last month are: $2287.5
Given that:
[tex]Clothing = \$366[/tex]
From the Pie chart, 13% of the total expenses were spent on clothing.
This means that
[tex]13\% \times Total = Clothing[/tex]
So, we have:
[tex]13\% \times Total = \$366[/tex]
Divide both sides by 13%
[tex]Total = \$366 \div 16\%[/tex]
[tex]Total = \$2287.5[/tex]
Hence, the total expenses are: $2287.5

Use the graph of f(x) to explain the relationship
between the real zeros of f(x) and its intercept(s).

A. f(x) has one real zero at --2 because the graph of the
function has an intercept at (0.-2).
B. f(x) has two real zeros at -4 and -2 because the
graph of the function has intercepts at (-4,0) and (0,
-2).
C. f(x) has no real zeros because the graph of the
function does not pass through (0,0).
D. f(x) has one real zero at 4 because the graph of the
function has an intercept at (-4, 0).
Answer:
D.f(x) has one real zero at 4 because the graph of the function has an intercept at (-4,0).

for f(x) evaluate each of the following:
a. f(0)
b. f(6)
show all your work
Answer:
Step-by-step explanation:
a)
f(0) is just the function f(x) evaluated at 0, meaning we need to plug in 0 to the function.
What piece of this function should we plug 0 in? Well, because 0 is less than 5, plug it into the first piece.
so f(0) = 0 + 4 = 5
b)
By similar reasoning:
f(6) = 8
because 5 <= 6 < 7
