Answer:
y=1.08x-2144.24
Step-by-step explanation:
find the slope: m=(19.00-13.60)/(2003-1998)=1.08
so we have y=1.08x +b
next, use the point (2003, 19.00) to find b:
19.00=1.08*2003 +b =>b=-2144.24
Chardai reads 25% of a book each night that has 280 pages. How many pages will she read
each night?
HINT: twenty-five percent OF 280
Answer:
70 pages
Step-by-step explanation:
Remember that in math, "of" usually means we multiply.
Here, Chardai reads 25% OF a 280-page book each night.
So, we multiply 25% by 280:
25% * 280 = (25/100) * 280 = (1/4) * 280 = 70
The answer is 70 pages.

2(5x – 2) – 2x– 2 = 34
Answer:
x =5
Step-by-step explanation:
2(5x – 2) – 2x– 2 = 34
Distribute
10x-4-2x-2 = 34
Combine like terms
8x -6 = 34
Add 6 to each side
8x-6+6 = 34+6
8x = 40
Divide by 8
8x/8 = 40/8
x =5

two eights of a circle is what percent of a circle
Answer:
25%
Step-by-step explanation:
2/8 is equal to 1/4.
Now lets just say that the entire circle is 100%, or completely filled.
1/4 of 100 is 25. Then since it's already in terms of one hundred, we can say that 2/8 of a circle is 25% of it.
Answer: 1/4
Step-by-step explanation: 1/8 is half of 1/4 and 2/8 if simplified is 1/4

[tex]\displaystyle \frac{3m^2n^2}{5(m+n)}\div \frac{12m^4n}{10(m+n)}=\displaystyle \frac{n}{2m^2}[/tex]
Step-by-step explanation:
Simplificación de expresiones algebraicas
Tenemos la expresión:
[tex]\displaystyle \frac{3m^2n^2}{5(m+n)}\div \frac{12m^4n}{10(m+n)}[/tex]
La división de fracciones suele manejarse mejor utilizando la multiplicación del inverso del denominador. Es decir, para dividir la fracción a/b entre la fracción c/d se multiplica a/b*d/c para resultar (a*d)/(b*c).
Apliquemos lo anterior al problema en consideración:
[tex]\displaystyle \frac{3m^2n^2}{5(m+n)}\div \frac{12m^4n}{10(m+n)}=\displaystyle \frac{3m^2n^2}{5(m+n)}\cdot \frac{10(m+n)}{12m^4n}[/tex]
Multiplicamos los coeficientes en el numerador y denominador y eliminamos el factor (m+n):
[tex]=\displaystyle \frac{30m^2n^2}{60m^4n}[/tex]
La potencia 2 de la m se simplifica con la potencia 4 y la potencia 2 de la n se simplifica con la potencia 1. Igualmente se simplifica la fracción numérica dividiendo entre 30:
[tex]\boxed{\displaystyle \frac{3m^2n^2}{5(m+n)}\div \frac{12m^4n}{10(m+n)}=\displaystyle \frac{n}{2m^2}}[/tex]

x is infinity which means it has no solutions.
Given,
4 = ax - 14
We need to solve for x.
We have,
4 = ax - 14
Now,
We have to assume a = 0.
we get,
4 + 14 = ax
ax = 4 + 14
x = (4+14) / a
x = 18 / a
So,
Putting a = 0 in x = 18 / a
We get,
x = 18/0 = ∞
We can say that x has no solutions.
Thus x is infinity which means it has no solutions.

What is the slope of the line y= 7x + 19 (5)
A line's slope or gradient, which is expressed as a number, indicates the line's steepness and X and Y directions.
The slope of the line y = 7x + 19 (5) exists 7.
What is meant by the slope of the line?The units of the slope (dy/dx), which correspond to speed or velocity, in this case are km/m.y since the y axis is measured in kilometres and the x axis in millions of years. Both the slope and the y intercept might have a positive or negative value. Slope is defined as the y-axis divided by the x-axis.
The slope expresses how quickly the dependent variable changes when the independent variable changes. The Greek capital letter D or D is frequently used by mathematicians and economics to represent change. Slope contrasts the change in the vertical axis, y, with the change in the horizontal axis, x.

Step-by-step explanation:
A baker puts a chocolate cake in the oven to bake for 30 minutes. Let f(t) = 0.25 + 65 be the temperature of the cake t minutes
after you placed it in the oven. Which of the following statements are true for the given function?
LET ME KNOW ASAP
Answer:
Options (1) and (5)
Step-by-step explanation:
Given function 'f' representing the relation between temperature of the oven after 't' minutes is,
f(t) = 0.25t² + 65
Option (1).
f(0) means that when the cake was placed in the oven, its temperature was 65°.
True.
f(0) = 0 + 65 = 65
Option (2).
To find the temperature after 15 minutes, we need to find 't' when f(t) = 15
False.
We have to find the value of f(15) to find the temperature of the oven after 15 minutes.
Option (3).
Temperature of the cake was 81° F when it was kept in the oven for 8 minutes.
Given statement is False.
It should be represented by,
f(8) = 81
Option (4).
After 10 minutes,the temperature of the cake was 71.25 degree F.
False.
By putting t = 10 in the function,
f(10) = 0.25(10)² + 65
= 25 + 65
= 90° F
Option (5).
The temperature of the cake when the baker takes it out of the oven, can be represented by,
f(30) = 290
True.
f(30) = 0.25(30)² + 65
= 225 + 65
= 290

Step-by-step explanation:
use system of equations and substitution.
to solve this equation, one variable needs to be cancelled out to solve for the other.
[tex]-5y+4y=4\\-7y-10x=-10\\[/tex]
looking at this problem, we can manipulate -5 and -7 to equal 35 and -35 to get rid of the variable x to solve for y.
[tex]-7(-5y+4x=4)\\5(-7y-10x=-10)\\\\35y-28x=-28\\-35y-50x=-50[/tex]
with this, we can cancel out 35x and -35x.
[tex]-28x=-28\\-50x=-50[/tex]
manipulate the equation to equal x.
[tex]x=1\\x=1.[/tex]
plug 1 for x back into one of the equations to solve for y.

how do i evaluate 3/7r+5/8s when r=14 and s=8
Answer:
11
Step-by-step explanation:
3/7r + 5/8s
r = 14
s = 8
3/7 x 14 + 5/8 x 8
3/7 x 14 = 6
5/8 x 8 = 5
6 + 5 = 11
ok so it's like the 3/7 and 5/8 are fractions so you just multiply each one by the number their next you which in this case is r and s so it's like you're just multiplying a fraction and a number. does that make since?

Which Statment is True?
a. The data distribution is both symmetric and skewed
b. the data distribution is skewed to the left
c.the data distribution is skewed to the right
d. the data distribution is symmetric
Given Correct Statement is :- The data distribution is skewed to the right, which means that the right tail of the distribution is longer than the left tail. c. The data distribution is skewed to the right.
It is not possible for a data distribution to be both symmetric and skewed at the same time, as these are mutually exclusive characteristics.
A symmetric distribution is one in which the data is evenly distributed around the mean, with the left and right sides of the distribution being mirror images of each other.
A skewed distribution is one in which the data is not evenly distributed around the mean, with one tail of the distribution being longer than the other.
Based on the given options, only one statement can be true.
Option (c) states that the data distribution is skewed to the right, which means that the right tail of the distribution is longer than the left tail. Therefore, the correct statement is:
c. The data distribution is skewed to the right.

4 2/3 ÷7
Answer:
2/3
Step-by-step explanation:
Convert the mixed fraction into an improper one:
4 2/3 = 4*3 + 2 / 3 = 14 / 3.
Then divide:
14/3 ÷ 7 = 14÷7 / 3 = 2 / 3
Answer:
14/21
Step-by-step explanation:
First, we turn 4 2/3 into an improper fraction. We do this by multiplying 4 by 3 and then adding 2 to this product.
4×3 = 12
12 + 2 = 14
Now, our equation is simplified to 14/3 ÷ 7. Now, all we can do is divide 14/3 by 7.
14/3 ÷ 7 = 14/21
So, our evaluated and simplified answer is 14/21.
Tom and Joe are racing towards each other in a game of "chicken." Each boy is riding in a plastic canoe. They are at the local YMCA pool and are starting at a distance of 100 feet apart. Tom is able to paddle at a speed of 4 feet per second. Joe is able to paddle at a speed of 6 feet per second. How long will it take for the boys to meet?
Answer:
50 seconds
Step-by-step explanation:
We are told in the question that the distance between them = 100ft
Tom is able to paddle at a speed of 4 feet per second. Joe is able to paddle at a speed of 6 feet per second.
The formula for Distance = Speed × Time.
Hence, the Algebraic equation is given as:
6ft/s × t = 4ft/s × t + 100
6t = 4t + 100
6t - 4t = 100
2t = 100
t = 100/2
t = 50 seconds
It will take 50 seconds for the boys to meet.

If PQR measures 75°, what is the measure of SQR?
22°
45°
53°
97°
Answer:
The Answer is 53
Step-by-step explanation:
if angle PQR is 75 and PQS is 22... 75-22 is 53
The measure of the angles SQR if PQR measures 75° is 53 degrees
What is Angle?An angle is formed by joining two rays (half-lines) that have a shared terminal. The latter is referred to as the angle's vertex, while the rays are referred to as the angle's sides, legs, and arms.
We have,
<PQR = 75 degrees
<PQS = 22 degrees
From the given diagram
<PQR = <PQS + <SQR
Substitute the given values into the formula
75 = 22 + <SQR
<SQR = 75 - 22
<SQR = 53 degrees
Hence, the measure of the angles SQR is 53 degrees
