a. a point
b. a line
c. a plane
d. an angle
The intersection of two coplanar lines forms a point.
Option A is the correct answer.
What are corresponding angles?The angles that are in the same position on two parallel lines intersected by a transversal line on the parallel lines.
Corresponding angles are equal.
We have,
The intersection of two coplanar lines forms:
a.
a point
This is true.
Because two lines that intersect and form a point are called coplanar.
b.
a line
This is not true.
c.
a plane
This is not true.
Two axis makes a plane.

Answer is marked by red colour.
Angelo, age 40, is comparing the premium for a $125,000 whole life insurance policy he may take now and the premium for the same policy taken out at age 45. Using the table, find the difference in total premium costs over 20 years for this policy at the two age levels. a. $69,375 b. $11,725 c. $12,875 d. $644
Policy value over 20 years = 125000
Per year, 125000/20=$6250
Look up premium table for age 40 and 45, the difference in total premium is C. $12,875.
To find the difference in total premium costs over 20 years for a whole life insurance policy at two age levels, calculate and subtract the total premium at each age.
Explanation:To find the difference in total premium costs over 20 years for the whole life insurance policy at the two age levels, we need to calculate the total premium at each age and then subtract the two values.
For Angelo at age 40, the value of the policy is $125,000. Let's assume the premium rate is x. So, the total premium at age 40 is 20 * x. For Angelo at age 45, the value of the policy is still $125,000. Let's assume the premium rate is y. So, the total premium at age 45 is 15 * y. To find the difference in total premium costs over 20 years, subtract the total premium at age 45 from the total premium at age 40: 20 * x - 15 * y.Therefore, the difference in total premium costs over 20 years for this policy at the two age levels is 20 * x - 15 * y.

D. 1 in 10,000,000
Answer: A. 1 in 100,000,000
Step-by-step explanation:
The given digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
The total number of digits = 10
Now by using the counting principle, the probability of choosing one number is given by :-

the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (3, 0 ) and (x₂, y₂ ) = (0, - 5 )
m = [tex]\frac{-5-0}{0-3}[/tex] = [tex]\frac{5}{3}[/tex]
line crosses y-axis at (0, - 5 ) hence c = - 5
y = [tex]\frac{5}{3}[/tex] x - 5 ← in slope-intercept form
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
rearrange slope-intercept form into standard form
multiply all terms by 3
3y = 5x - 15 ( subtract 3y and add 15 to both sides )

if i have a pay rate of $21.00 and marked up 78.7% and made a 10% profit. how did i get $41.28?
Step-by-step explanation:
Since we have given that
Amount of pay rate =$21
If she marked up by 78.7% , so it becomes
[tex]78.7\%\text{ of}\$21\\\\=\frac{78.7}{100}\times \$21\\\\=\$16.527[/tex]
So, our amount for pay rate becomes
[tex]21+16.527\\\\=\$37.527[/tex]
Now, he said he made a profit of 10%,so it becomes
[tex]10\%\text{ of }37.527\\\\=\frac{10}{100}\times 32.527\\\\=\$3.7527[/tex]
So, our new pay rate becomes
[tex]37.527+3.7527\\\\=\$41.2797[/tex]
This is the step through which we can get $41.28.

The number of counties in state A and the number of counties in state B are consecutive even integers whose sum is 142. If state A has more counties than state B, how many counties does each state have?
Let the number of counties in state B be n, then the number of counties in state A is n+2 (the next even integer number after n). The sum of these two consecutive integers is 142, then
n+n+2=142,
2n=142-2,
2n=140,
n=70.
In state B there are 70 counties, and in state A there are 72 counties.
What is the value of arcsin (-0.18)? Use a calculator to determine the answer.
Answer:
A) -0.18 rad
Step-by-step explanation:
arcsin(x) = a means that sin(a) = x
For example
arcsin(1) = pi/2.
It means that pi/2 is the value for which the sin is equals to 1.
arcsin(-0.18)
This is the value of x for which sin(x) = -0.18. This happens for x = -0.18 rad.
So the correct answer is:
A) -0.18 rad

Bedspread:
$39.95 x 3 = $119.85
Gallon of paint:
$24.96 x 3 = $74.88
Lamp shade:
$9.99 x 3 = $29.97
The cost of all the items:
$73.50 + $119.85 + $74.88 + $29.97 = $298.20
How much money is left:
$325 - $298.20 = $26.80

Suppose the roots of a polynomial are 3 4 , − 7 8 , − 3 8 , and − 1 9 . Which choice is a factor of the polynomial?
A) (x +3/4)
B) (x + 3/8)
C) (x - 7/8)
D) (x - 1/9)
Answer:
x+7/8
Step-by-step explanation:
A polynomial has roots at the points where the curve cuts the x axis.
This can also be said as values of x for which the polynomial is 0
Given that when x =a is root means, we have x-a is the factor.
Based on the above, we find when 3/4, -7/8, -3/8 and -1/9 are roots
factors are x-3/4, x+7/8, x+3/8, x+1/9
Hence answer is
B) (x + 3/8)
The other options do not match with the factors only option Bmatches.
Answer: The factor of the polynomial is [tex](x+\frac{3}{8})[/tex]
Step-by-step explanation:
We are given:
4 roots of the polynomial
Root 1: [tex]\frac{3}{4}[/tex]
The factor for this root becomes: [tex](x-\frac{3}{4})[/tex]
Root 2: [tex]\frac{-7}{8}[/tex]
The factor for this root becomes: [tex](x+\frac{7}{8})[/tex]
Root 3: [tex]\frac{-3}{8}[/tex]
The factor for this root becomes: [tex](x+\frac{3}{8})[/tex]
Root 4: [tex]\frac{-1}{9}[/tex]
The factor for this root becomes: [tex](x+\frac{1}{9})[/tex]
Hence, the factor of the polynomial is [tex](x+\frac{3}{8})[/tex]

that is, 13x + 5 ≠ 18x
13x + 5 + 17x - 4.5 + x

= 31x + 0.5 ← correct simplification
combining terms in x with constants
13x + 5 ≠ 18x
13x + 5 + 17x - 4.5 + x
= (13x + 17x + x ) + 5 - 4.5 <--- collecting like terms

Write an expression for the calculation divide 10 in half and subtract from 50 divide into fifths
There are several issues with this English description, as there often are.
We assume you mean you want to divide 10 into two equal parts, then subtract one of those parts from 50.
... (10/2) is half of 10
When that is subtracted from 50, the result is
... 50 - (10/2)
We assume you want one fifth of this result. Other interpretations are that you are subtracting 10/2 from (50/5), or that you are using the difference as the denominator with 1/5 or some other number of fifths as the numerator (dividing <the difference> into 1/5).
Then your expression might be ...
... (1/5)(50 -10/2)

{362- 66+3(9+4)
{296+3(13)}
(296+39)
335
The Answer is 335.
To evaluate the expression {362-[6×3+(48÷2)×2]}+3(9+4), we need to follow the order of operations. After simplifying each part of the expression and performing the necessary operations, the final result is 287.
Explanation:To evaluate the expression {362-[6×3+(48÷2)×2]}+3(9+4), we need to follow the order of operations, also known as PEMDAS. This acronym stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
First, let's simplify the expression inside the parentheses: [6×3+(48÷2)×2].
Using the division rule, we have: [6×3+(24)×2].Next, we perform the multiplications: [18+48×2].Then, we simplify further: [18+96].The sum inside the parentheses is equal to 114. Therefore, the expression becomes {362-114}+3(9+4).Next, let's evaluate the expression inside the curly braces: {362-114}. This can be done by subtracting 114 from 362, resulting in 248.Finally, we have to evaluate the expression 3(9+4). Following the order of operations, we perform the addition inside the parentheses first: 3(13). Multiplying 3 by 13 gives us 39.Now, we add the results of the two evaluated expressions: 248+39. This gives us a final result of 287.

what is the y-intercept of (2, 18) and (6, 6)?
Assuming you want the y-intercept of the line through those two points, you can find it a couple of different ways.
The slope of the line is ...
... slope = (change in y)/(change in x) = (6-18)/(6-2) = -12/4 = -3
We are given the y-value for x=2. When x decreases by 2 to x=0, then the y-value changes by (-2)·(-3) = +6, from 18 to 24.

You can also write the equation of the line in point-slope form as ...
... y = -3(x -2) +18
Again, when x=0, the y-intercept is ...
... y = -3(0 -2) +18 = 6 +18 = 24
The y-intercept of the line through (2, 18) and (6, 6) is 24.
