The equation that models the situation is f(t) = 10 + 9t.
The carpenter has already shingled 10 garage roofs . The initial amount he has already shingled is like a constant in the equation.
He shingles at a constant rate of 9 per day. This means each day the carpenter shingles 9 roofs.
let
f(t) = number of garage roofs the carpenter shingles
t = time in days.
If the carpenter shingles 9 roofs per day , he will shingle 9 × t roof for t days.
To model the equation where he had already shingled 10 roofs and his shingling rate, can be represented as follows:

Mikey is reading a 604-page book. He read 148 pages last week. If he reads for x hours at 19 pages per hour, which equation represents how long it will take him to finish the book?
A.
148x + 19 = 604
B.
19x + 604 = 148
C.
19x + 148 = 604
D.
19x - 148 = 604
Answer:
C
Step-by-step explanation:
first take off the 148 of the 604 page book then divide the rest by 19 ,
it should be 24 hours - 1-day .
it is c because it shows my explination because 19x + 148 is equal to 604 first take the 148 and 19 and x means multiplication so 19 times 24 = 456.
What is the equation of the line that passes through the point (-4, 2) and
has a slope of -2?
Answer:
y-2 = -2(x+4)
or
y = -2x-6
Step-by-step explanation:
We can use the point slope form of a line
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y - 2 = -2(x- -4)
y-2 = -2(x+4)
If we want the equation in slope intercept form
Distribute
y-2 = -2x-8
Add 2 to each side
y-2+2 = -2x-8+2
y = -2x-6

153Regular consumption of presweetened cereals contributes to tooth decay, heart disease, and other degenerative diseases, according to studies conducted by Dr. W. H. Bowen of the National Institute of Health and Dr. J. Yudben, Professor of Nutrition and Dietetics at the University of London. In a random sample consisting of 20 similar single servings of Alpha-Bits, the average sugar content was 11.3 grams with a standard deviation of 2.45 grams. Assuming that the sugar contents are normally distributed, construct a 95% confidence interval for the mean sugar content for single servings of Alpha-Bits.
Using the t-distribution, the 95% confidence interval for the mean sugar content for single servings of Alpha-Bits is (10.15, 12.45).
In this problem, we have that:
Sample of 20, thus [tex]n = 20[/tex].Sample mean of 11.3 grams, thus [tex]\overline{x} = 11.3[/tex].Sample standard deviation of 2.45 grams, thus [tex]s = 2.45[/tex].The confidence interval is:
[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]
First, we find the number of degrees of freedom, which is one less than the sample size, thus df = 19.
Now, we have to find the critical value for a 95% confidence interval with 19 df, thus, looking at the t-table or using a calculator, t = 2.093.
Then:
[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 11.3 - 2.093\frac{2.45}{\sqrt{20}} = 10.15[/tex]
[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 11.3 + 2.093\frac{2.45}{\sqrt{20}} = 12.45[/tex]
The interval is (10.15, 12.45).

Watson and Alva each have the same total number of toy cars and trucks Watson has 4 boxes. Each of his boxes has 7 cars and 2 trucks. Alva
has 2 boxes. Each of his boxes has 11 cars and the same number of trucks
How many trucks are in each of Alva's boxes?
Answer:
Alva has 7 trucks in each box.
Explanation:
You need to determine the total number of toys Watson has. Watson has 4 (7+2) = 4(9) = 36 toys.
Set 36 equal to an expression for the number of toys Alva has. Using t for the number of trucks, 36 = 2 (11+t).Then, solve the equation.
36 = 2(11+t) 36 = 22 + 2t 14 = 2t7 = tSo how many trucks are in each of Alva's boxes?
7 Trucks!The number of trucks that Alva has is 7.
How many trucks does Alva have?A linear function is a function that is made up of a single variable that is raised to the power of one.
The general form of a linear equation is:
y = mx + b
Where:
y = dependent variable b = constant m = independent variableThe first step is to determine the total number of toy cars and trucks that Watson has.
Total number of toy cars and trucks that Watson has = (4 x 7) + (4 x 2)
= 28 + 8 = 36
Since Watson and Alva have the same number of toy cars and trucks, it means that Alva would also have 36 toy cars and trucks.
The equation that represents the total number of toy cars and trucks that Alva has is:
(2 x 11) + (2 x t) = 36
22 + 2t = 36
36 - 22 = 2t
14 = 2t
t = 14 / 2
t= 7

The area of a rectangle is x^2-4/2x in.2, and its length is (x + 2)2/2 in. Find the width.
Step-by-step explanation:
the area (length × width) is
A = (x² - 4)/2x in² = (x + 2)(x - 2)/2x
length = (x + 2)²/2 = (x + 2)(x + 2)/2
width = A/length = 2(x+2)(x-2) / 2x(x+2)(x+2) =
= (x-2)/x(x+2) = (x-2)/(x²+2x)

hey i need help with how to multiply 8/9 and 1/4. HELP ME OOOUUUUTTTT!!!!!!!!!!!!!!
Explanation:
Multiply the numbers up top: 8*1 = 8
Multiply the numbers in the bottom: 9*4 = 36
The two fractions 8/9 and 1/4 multiply to 8/36. Reduce this to 2/9 after dividing both parts by the GCF 4.
In other words,
8/4 = 2
36/4 = 9
Hello there! :)
When multiplying fractions, we multiply the numerator times the numerator and the denominator times the denominator. We reduce if it's necessary.
So multiply:
[tex]\frac{8}{9} *\frac{1}{4} \\[/tex]
Reduce and get:
[tex]\frac{2}{9} *\frac{1}{1} \\\frac{2}{9}[/tex]
And that's our final answer. Hope it helps you!

Noah’s remote control car moved 12 feet in 6 seconds. Which graph has a slope that best represents Noah’s car’s average rate of speed?
We want to find a graph that represents Noah's average speed.
We define the average speed as the quotient between the distance moved and the time it takes to move that distance, then in this case we will have:
s = 12ft/6s = 2ft/s
Then we can define a linear equation:
y = (2ft/s)*x
As the distance that Noah travels in x seconds.
The graph of the given linear function can be seen below, and that is the graph with the slope that best represents Noah's average speed.
