A plumbing contractor charges a fee of $100 a visit and an additional charge of $50 per hour. Which equation can be used to find the number of hours x he worked if he gets paid $950 for a day's work?
Answer:
100 + 50x = 950
100 - 100 + 50x = 950 - 100
50x = 850
50x/50 = 850/50
x = 17

Solve the proportion.
7
b
21
18
b = [?]
Answer:
b = 6
Step-by-step explanation:
here's your solution
=> 7/21 = b/18
=> by cross multiplication
=> 21b = 7*18
=> b = 126/21
=> b = 6
hope it helps
Answer:
b = 6
Step-by-step explanation:
To find the answer, find the GCF of 7 and 21, which is 7, and divide it by 7/7 to get 1/3, now the equation is 1/3 = b/18. How many times does 3 multiply to get 18? 6, multiply the first side of the equation by 6/6 to get 6/18, now we have 6/18 = b/18, since they are the same, b = 6

On a coordinate plane, parallelograms A B C D and E F G H are shown. Parallelogram A B C D has points (4, 2), (7, 2), (4, 6), (1, 6). Parallelogram E F G H has points (negative 2, 2), (negative 5, 2), (negative 6, 6), and (negative 3, 6). How do the areas of the parallelograms compare? The area of parallelogram ABCD is 4 square units greater than the area of parallelogram EFGH. The area of parallelogram ABCD is 2 square units greater than the area of parallelogram EFGH. The area of parallelogram ABCD is equal to the area of parallelogram EFGH. The area of parallelogram ABCD is 2 square units less than the area of parallelogram EFGH.
Answer:
The area of parallelogram ABCD is equal to the area of parallelogram EFGH.
Step-by-step explanation:
Given
Parallelogram ABCD
[tex]A = (4,2)[/tex]
[tex]B = (7,2)[/tex]
[tex]C =(4,6)[/tex]
[tex]D = (1,6)[/tex]
Parallelogram EFGH
[tex]E =(-2,2)[/tex]
[tex]F = (-5,2)[/tex]
[tex]G = (-6,6)[/tex]
[tex]H = (-3,6)[/tex]
Required
Compare the areas of both parallelograms
The area of a parallelogram is:
[tex]Area =Base * Height[/tex]
So: To do this, we plot ABCD and EFGH on a grid, then we measure the base and the height of both.
See attachment 1 for ABCD
In (1), we have:
[tex]Base = 3\ units[/tex]
[tex]Height = 4\ units[/tex]
So, the area is:
[tex]A_1 = 3 * 4[/tex]
[tex]A_1 = 12[/tex]
See attachment 2 for EFGH
In (2), we have:
[tex]Base = 3\ units[/tex]
[tex]Height = 4\ units[/tex]
So, the area is:
[tex]A_2 = 3 * 4[/tex]
[tex]A_2 = 12[/tex]
By comparison, they both have the same areas

If I roll a dice 120 times how many times I expect to get a 2
Answer:
If one rolls a dice 120 times, he/she expect to get a 2, 20 time
Step-by-step explanation:
The probability of getting a 2 when the dice is rolled 1 time is [tex]\frac{1}{6}[/tex]
Given - The dice is rolled for 120 times
Probability of getting a 2 is
[tex]\frac{1}{6} *120\\= 20[/tex]
Thus, if one rolls a dice 120 times, he/she expect to get a 2, 20 time
At a computer store, a tablet computer was on sale for 10% off. If the original price of the tablet
was P, what is the sale price in terms of P?
P-10
P-0.10
0.90P
0.10P
Answer:
the discounted price by 10% is P(x) = 0.9x. the price minus a $150 coupon is C(x) = x - 150. so, if you go to the store, the item is discounted by 10%, so you're really only getting out of your pocket 90% of that, or 0.9x, but!!
The sale price of a tablet computer is option (C) 0.90P is the correct answer.
What is sale price?Sale price is the price that a customer pays to purchase a product or a commodity. It is a price above the cost price and includes a percentage of profit also. The price after the original price has been reduced by a discount.
For the given situation,
The discount of a tablet computer = 10% = 0.10
The original price of the tablet = P
Sale price = original price - original price(discount)
⇒ [tex]P-P(0.10)[/tex]
⇒ [tex]P(1-0.10)[/tex]
⇒ [tex]P(0.90)[/tex]
Hence we can conclude that the sale price of a tablet computer is option (C) 0.90P is the correct answer.

PLEAES HELP HURRY i will give brainliest
sfdfgjhndghjStep-by-step explanation:
Answer:
The answer is J.
Step-by-step explanation:
To find the slope of the line, pick two dots on that are EXACTLY on the grid.
I picked (0,3) and (2,2)
First, count how many units down the two points are from each other
I counted one.
Then, count how many units they are away from the side.
I got 2.
Slopes are rise over run or y over c so the slope is 1/2
The line is negative, too as it is going down so the slope is negative.
Therefore, the slope is -1/2 and only one option have a slope of -1/2 and it’s J
Also, to know which number is the slope look for the number before the x. In slope intercept form, that is the slope.
1/6 into a decimal and percent WILL REPORT AND GIVE BRAINLYEST
Answer:
1/6 = 0.167 or 16%
Step-by-step explanation:
Okay, so to go from a fraction to a decimal, you really just have to put the dot in the right place:
1/6 = 0.167 (rounded)
So 1/6 is 0.167 as a decimal
So to find the percentage:
0.167 x 10 = 16.7
So 1/6 is 16.7%
hope this helps:)
Answer:
Decimal: 0.166666667
Percent: 16.6666667%
Step-by-step explanation:
First a decimal:
Divide 1 ÷ 6: 0.166666667
Now a percent, to convert decimals to percents multiply them by 100 and add the percent sign:
0.166666667 ⋅ 100 = 16.6666667%
The area of a rectangular garden is 96 square feet. The width is 4 feet less than the length. What is the length of the garden?
9514 1404 393
Answer:
12 ft
Step-by-step explanation:
We can let x represent the average of length and width. Then the length is x+2, and the width is x-2. Then the area is ...
(x +2)(x -2) = 96
x^2 = 100
x = √100 = 10
The length is x+2, so ...
the length of the garden is 12 feet.
