Step-by-step explanation:
what must be the value of a and b for PQRS to be a parallelogram?
Answer:
a = 2
b = 4
Step-by-step explanation:
In parallelogram opposite sides are equal.
4a + b = 2a + 8
4a - 2a + b = 8
2a + b = 8 -----------------(I)
b = 8 - 2a
11b - 10a = 6b
11b - 6b -10a = 0
5b - 10a = 0 ---------(II)
Substitute b = 8 - 2a in equation (II)
5*(8-2a) - 10a = 0
5*8 - 2a * 5 - 10a = 0
40 - 10a - 10a = 0
40 - 20a = 0
-20a = - 40
a = -40/-20
a = 2
Plugin a = 2 in equation (I)
2*2 + b = 8
4 + b = 8
b = 8 -4
b = 4
The perimeter of a right triangle is 60 feet and the area is 150 square feet. If the lengths of the sides of the triangle are each multiplied by 10, what is the perimeter of the new right triangle? A. 500 ft. B. 600 ft. C. 7120 ft. D. 8640 ft.
Answer:
B. 600 ft
Step-by-step explanation:
The formula for the Perimeter of a right triangle = Side a + Side b + Side c
The perimeter of a right triangle is 60 feet
If the lengths of the sides of the triangle are each multiplied by 10, what is the perimeter of the new right triangle?
Hence, the perimeter of the new right triangle = 10 × 60ft
= 600ft
Option B is the correct Option.
Answer:
600
Step-by-step explanation:
Which quotient shows the decimal placed correctly? A) 6÷0.5=1.2 B) 0.64÷2=3.2 C) 0.57÷5=0.114 D) 1.08÷0.3=0.36
Answer:
C) 0.57÷5=0.114
Step-by-step explanation:
Which quotient shows the decimal placed correctly?
Solving for each of the option
A) we are told that:6÷0.5=1.2
Hence: 6/0.5
= 12
Option A is wrong
B) we are told that: 0.64÷2=3.2
Hence: 0.64/2
= 0.32
Option B is wrong
C) we are told that: 0.57÷5=0.114
Hence: 0.57/5
= 0.114
Option C is correct
D) we are told that: 1.08÷0.3=0.36
Hence = 1.08/0.3
= 3.6
Option D is wrong
Therefore, option C is the only correct Option where the quotient shows the decimal placed correctly

A pigeon flies for 7 hours at a speed of 70 km/h.
Calculate how far the pigeon flies.
Answer:
490km
Step-by-step explanation:
70km/hrs for 7hrs
so if the pigeon flies 70km in one hour we just have to multiply 70 by 7 to get 7hours.
70x7=490km
That means the pigeon flies 490km in 7hrs
Andrea works as a cashier in a music store. A customer wants to buy a CD that is
on sale for 15% off the regular price of $14.00. This means she will pay 85% of
$14.00. How much will Andrea pay?
Answer:
$11.90
Step-by-step explanation:
first you change the percent to a decimal by moving the decimal two places and then multiply.
you multiply .85 and 14.00= 11.90
Answer:
$11.9
Step-by-step explanation:
The regular cost of the CD = $14:00
The discount she gets = 15%
So, 15% of $14 = 2.1
= $14 - $2.1 = $11.9
Another method:
Or u can take 85% of $14 and u will get the immediately
85% of $14 = $11.9
This relation is an inverse variation. {(–1, 8), (4, –2), (–2, 4)} Which equation represents this relation?
Answer:
[tex]y = -\frac{8}{x}[/tex]
Step-by-step explanation:
Given
Inverse Variation:
[tex]Points: \{(-1, 8), (4, -2), (-2, 4)\}[/tex]
Required
Determine the equation of the relation
An inverse relation is represented as:
[tex]y = \frac{k}{x}[/tex]
Where k = constant of variation
Make k the subject:
[tex]k = xy[/tex]
When x = -1, y = 8
So, we have:
[tex]k = -1 * 8[/tex]
[tex]k = -8[/tex]
When x = 4, y = -2
[tex]k = 4 * -2[/tex]
[tex]k = -8[/tex]
When x = -2, y = 4
[tex]k= -2 * 4[/tex]
[tex]k = -8[/tex]
From above calculations, we've established that:
[tex]k = -8[/tex]
Substitute -8 for k in [tex]y = \frac{k}{x}[/tex]
[tex]y = \frac{-8}{x}[/tex]
[tex]y = -\frac{8}{x}[/tex]
Hence, the equation is:
[tex]y = -\frac{8}{x}[/tex]
If 1 gram = 100 centigrams and 1 centigram = 10 milligrams, how many
milligrams are in 1.42 grams?
0.142
142
1,420
14,200
Answer:
1,420 milligrams
Step-by-step explanation:
We know there are 100 centigrams in 1 gram, and there are 10 milligrams in a centigrams. That would mean there are 1,000 milligrams in 1 gram (100 * 10 = 1000).
As a result, all you need to do is multiply 1.42 by 1000 to get the amount of milligrams.
1.42 * 1000
Alternatively, to make 1.42 a whole number first, multiply by 100, then add a zero. (That's the other 10!)
(1.42 * 100) * 10
142 * 10
There are 1,420 milligrams in 1.42 grams.

Yoko needs 300 copies of her resume printed. Dakota printing charges 19.50$ for the first 200 copies and 9$ for every 100 additional copies. If the number of sets of 100 resumes is represented by r, express the cost of the resumes c(r) algebraically as a piecewise function How much will 300 copies cost, including a sales tax of 4 1/2%? Round to the nearest cent.
Answer:
A. c(r)=$19.5 if r < 2
c(r)=$19.5+(r-2) ($9) (1.045) if r ≥ 2
B. $29.78
Step-by-step explanation:
A. Based on the information given if we are to express the cost of the resumes which is c(r) algebraically as a piecewise function what we would have will be:
c(r)=$19.5 when r represent an INTERGER and is less than 2
c(r)=$19.5+(r-2) ($9) (1+0.045)
c(r)=$19.5+(r-2) ($9) (1.045) when r represent an INTERGER and is greater than 2
Therefore to express the cost of the resumes c(r) algebraically as a piecewise function will be: c(r)=$19.5 if r < 2
c(r)=$19.5+(r-2) ($9) (1.045) if r ≥ 2
B. Calculation for How much will 300 copies cost, including a sales tax of 4 1/2%
Cost of 300 copies=($19.5+$9)+($19.5+$9) (0.045)
Cost of 300 copies=$28.5+$28.5(0.045)
Cost of 300 copies=$28.50+$1.28
Cost of 300 copies=$29.78
Therefore How much will 300 copies cost, including a sales tax of 4 1/2% will be $29.78

Answer:
a
Step-by-step explanation:
the answer is a because every week it shows (shows on the graph) that he is earning 6 dollars.
Answer:
A
Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ] and we can use the points (0, 0) and (5, 30) to solve.
30-0/5-0
30/5
6/1
6
Now that we know what the slope is, we can eliminate C and D.
This means that he saves around $6 per week. With this being said, we can eliminate B as well.

Chick-fil-A has three drive-thru lanes. Depending on the day and time of day, they sometimes
close all or some of the lanes. Let the random variable X represent the number of lanes that
are open on a randomly selected time during the week. The table shows the probability
distribution of X.
Part (a): What is the probability that at least one lane is open at a randomly selected time?
Part (b): What is the expected value of number of open lanes at a randomly selected time?
Part (c): What is the probability that all three drive-thru lanes are open, given that at least one lane is open?
Part (d): Given that at least one drive-thru lane is open, would the expected value of the number of open lanes be less than, equal to, or greater than the expected value from part b?

(5x6) (3x-2)=15xn. Find "n"
Answer:
[tex]\frac{6x-4}{x}[/tex]
Step-by-step explanation:
(5 x 6)(3x - 2) = 15xn
30(3x - 2) = 15xn
[tex]\frac{2}{1}[/tex] * (3x - 2) = ([tex]\frac{1}{2}[/tex]xn) * [tex]\frac{2}{1}[/tex]
6x - 4 = xn
n = [tex]\frac{6x-4}{x}[/tex]

What is the distance from (5,-5) to (-5,-5)?
Answer: 10
Step-by-step explanation:
What is the rate of this answer ??
Answer:
Option (4)
Step-by-step explanation:
Let the input output values of the table are represented by the equation,
y = mx + b
Here m = rate
b = y-intercept
Since, at x = 0, y = -1 [Point given in the table]
y-intercept 'b' = 0
Rate = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are two points given in the table.
If the points are (-2, -5) and (-1, -3),
Substitute the values in the formula,
Rate = [tex]\frac{(-5)-(-3)}{(-2)-(-1)}[/tex]
= [tex]\frac{-5+3}{-2+1}[/tex]
= 2
Therefore, Option (4) will be the answer.
Problem 1: Tyler reads 2/3 of a book on Monday, 1/3 of it on Tuesday, 2/9 of it on Wednesday, and 3/4 of the remainder on Thursday. If he still has 14 pages left to read on Friday, how many pages are there in the book?
Answer:
180 pages
Step-by-step explanation:
Let
x = total number of pages
Monday + Tuesday + Wednesday
2/15x + 1/3x + 2/9x
= (6x+15x+10x)/45
= 31/45x
Thursday
x - 31/45x
= (45x-31x)/45
= 14/45x
3/4 of 14/45x
= 3/4 * 14/45x
= 42/180x
Total pages read = 31/45x + 42/180x
= (124x+42x)/180
= 166/180x
If he still has 14 pages left to read on Friday
Total read from Monday to Thursday + Friday
x = 166/180x + 14
x - 166/180x = 14
(180x-166x)/180 = 14
14/180x = 14
x = 14 ÷ 14/180
x = 14 × 180/14
x = 180 pages
