The length of a rectangle is 3 less than twice the width. The perimeter of the rectangle is 66. Find the length and width of the rectangle.
Answer:
15.
Step-by-step explanation:
L + L + W + w = 66
L= w+3
W+3 + w+3 + w + w = 66
4xw + 6 = 66
4xw = 66 - 6
4xw = 60
W + W +w +w =60
W= 60/4
W=15
L = 15+3 (=18)
15+15+18+18=66
Which is a graph of a proportional relationship?
Which one?
Answer:
third graph (choice three/bottom left)
Step-by-step explanation:
Anything with a proportional relationship will always have a constant ratio (ratios will always be equivilent).
you can eliminate any graph that has an x or y intercept other than zero, or does not have a straight line.
The two main rules of a proportional graph or direct proportion is that:
the line must go through the origin (0,0)the graph must be linearAnswer:
the bottom left one
Step-by-step explanation:
it starts at the origin and as the x value increases, the y value increases too
you can easily rule out out the top two just because it doesn't start at the origin

Identify the x and y intercepts 10x+4y=-20
Answer:
(-2,0) and (0,-5) on the graph for the interprets x and y.
Note: I need points lol, pls put thanks and vote your stars for me! Thx!
The required x and y-intercept of the given equation is x = -2 and y = -5.
Given that,
An equation of the linear function is given 10x + 4y =-20, x and y-intercept of the function are to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
Given a linear function,
10x + 4y = -20
In order to get the values of the intercept we have to put x and y to zero individually,
First, for x-intercept y = 0
10x + 4(0) = -20
10x=-20
x = -2
Second for y-intercept x = 0
10(0) + 4y = -20
y = -5
Thus, the required x and y-intercept of the given equation is x = -2 and y = -5.

In baseball, two statistics, the ERA (Earned Run Average) and the WHIP (Walks and Hits per Inning Pitched), are used to measure the quality of pitchers. For both measures, smaller values indicate higher quality. The following computer output gives the results from predicting ERA by using WHIP in a least-squares regression for the 2017 baseball season.
Variable DF Estimate SE T
Intercept 1 −5.0 0.26 −19.3
WHIP 1 6.8 0.14 47.4
Which of the following statements is the best interpretation of the value 6.8 shown in the output?
a. ERA is predicted to increase by 6.8 units for each 1 unit increase of WHIP.
b. WHIP is predicted to increase by 6.8 units for each 1 unit increase of ERA.
c. For a pitcher with 0 units of WHIP, the ERA is predicted to be approximately 6.8 units.
d. For a pitcher with 0 units of ERA, the WHIP is predicted to be approximately 6.8 units.
e. Approximately 6.8% of the variability in ERA is due to its linear relationship with WHIP.
The equation for line w is y = 2x – 3. Line d contains the point (4, -1) and is parallel to line w. Which equation
describes line d?
Answer:
y = 2x - 7
Step-by-step explanation:
y = 2x - 3
Gradient of line w = 2
Gradient of line d = 2
i.e line w and d are parallel.
Equation of line d is:
y - (-1) = 2(x - 4)
y + 1 = 2x - 8
y = 2x - 7

how many hundredths are in 11 wholes?
how many hundredths are in 3 tenths?
how many hundredths are in 11.3?
pls help!!!
Answer:
1) 11/100 or 0.11
2) 3/1000 or 0.003
3) 113/1000 0.113
Step-by-step explanation:
Firstly, hundredths is the same as 1/100.
Multiply every number by 1/100.
11/1 • 1/100 = 11/100 or 0.11
(Remember, 11 over 1 is the same as 1. Multiply the numerators and denominators and you get 11/100).
3/10 • 1/100 = 3/1000 or 0.003
11.3/1 • 1/100 = 113/1000 or 0.113
(Move the decimal once to the right to get rid of the decimal point).

Please find the measure of the exterior angle
Answer:
exterior angles:
144°and 36°
126° and 54°
90° and 90°
Step-by-step explanation:
we know that each angle in a triangle adds up to 180°.
so,
2x+3x+5x=180
10x=180
x=180/10
x=18
the interior angles are:
2x=36°
3x=54°
5x=90°
and explanation is provided to find the exterior angles above.(sorry for the bad handwriting)

Suppose you want to accumulate $25,000 as down payment on a house and the best you can do is to put aside $200 a month. If you deposit this amount at the beginning of each month in an account that credits 0.75% interest monthly, how long will it take you to attain your goal?
Answer:
It will take 88.2 months to accumulate the amount
Step-by-step explanation:
Given;
Future value of money, FV = $25,000
investment per compound period, P = $200
interest rate, i = 0.75% x 12 = 9%
The number of monthly installments required to amount to FV is given by;
[tex]n = \frac{ln(FVi +cp)-ln(cp)}{ln(c+i)-ln(c)}\\\\ n = \frac{ln(25000*0.09 +200*12)-ln(200*12)}{ln(12+0.09)-ln(12)}\\\\n = \frac{8.4446 -7.7832}{2.4924-2.4849}\\\\n = 88.2 \ months[/tex]
Therefore, it will take 88.2 months to accumulate the amount.
