Step-by-step explanation:
3 consecutive numbers can be:
[tex]x-1, x, x+1[/tex] ; for example: 1, 2, 3 (1 is 1 less than 2, and 3 is 1 more than 2)
The sum is all of them added, so
[tex]x-1+x+x+1=270; 3x=270; x=90[/tex]
90 is the middle number though, so the first number is 89

The graph shows the number of books Rahul read, y, compared with the number of books Maggie read, x, over the summer.
Which equation represents the relationship between the number of books read by Rahul and Maggie?
A. y=x+2
B. y=x+1
C. y=3x
D. y=2x
Answer:
D. y=2x(4×2)
Step-by-step explanation:
y=8 and x=4 and they are asking about the books that Maggie read how they the books re equal to the ones Rahul read. so y will be equal to x times 2 which is also x+x.

Zane received a quote to move his belongings to his new house. The estimate from
the mover is $675 for 6 hours of packing and 5 hours of loading on the weekend. The
cost during the week is $425 for 4 hours of packing and 3 hours of loading. If the
mover charges a set hourly rate for packing and another set hourly rate for loading,
what are these hourly rates?
What is the LCM for packing? What is the LCM for loading?
9514 1404 393
Answer:
packing: $50 per hourloading: $75 per hourpacking LCM: 12; loading LCM: 15Step-by-step explanation:
We can let P and L represent the hourly costs of packing and loading, respectively. The two estimates can be represented by the equations ...
6P +5L = 675
4P +3L = 425
The LCM of the coefficients of P is LCM(6, 4) = 12.
The LCM of the coefficients of L is LCM(5, 3) = 15.
__
Each LCM is the product of the numbers, divided by their greatest common factor. For 4 and 6, the product is 24, and both even numbers have a factor of 2, so the LCM of 4 and 6 is 24/2 = 12. The numbers 3 and 5 have no common factors, so the LCM is simply their product.
_____
The LCM is useful if you're going to solve the equations by "elimination". Here, the LCM of 12 means we can eliminate P by making its coefficient be 12 in both equations. Multiplying the first equation by 2, we can subtract 3 times the second equation to eliminate P:
2(6P +5L) -3(4P +3L) = 2(675) -3(425)
12P +10L -12P -9L = 1350 -1275
L = 75 . . . . . simplify
Similarly, we can eliminate L by making its coefficients be 15.
5(4P +3L) -3(6P +5L) = 5(425) -3(675)
20P +15L -18P -15L = 2125 -2025
2P = 100 . . . . simplify
P = 50 . . . . . . divide by 2
The hourly rates are ...
$50 per hour for packing
$75 per hour for loading
Answer:
40 packing and 80 moving

How much money would you have in an account after 15 years if you earned 9,3% annually and you started with R573,00?
Given:
Principal = R573.00
Rate of interest = 9.3% annually
Time = 15 years.
To find:
The amount after 15 years.
Solution:
Formula for amount is:
[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]
Where, P is principal, r is the rate of interest in decimal, n is the number of time interest compounded in an year and t be the number of years.
The interest is compounded annually, so n=1.
Putting [tex]P=573,r=0.093,n=1,t=15[/tex] in the above formula, we get
[tex]A=573\left(1+\dfrac{0.093}{1}\right)^{1(15)}[/tex]
[tex]A=573\left(1+0.093\right)^{15}[/tex]
[tex]A=573\left(1.093\right)^{15}[/tex]
[tex]A=2174.98893[/tex]
[tex]A\approx 2174.99[/tex]
Therefore, the amount in the account after 15 years is about R2174.99.
Nikki is braiding her hair. She wants to make 48 little braids. If it takes her 4
minutes to make each braid, how many hours will it take her to make all 48
braids? *
Answer:

48x4=192
192 divided by 60 is 3.2
Answer:
3 hours and 12 minutes
Step-by-step explanation:
there are 15 sets of 4 in one hour, so 15 plus 15 equals 2 hours or 30 braids. Then you add one more hour and you get 45 braids and then for the last three braids its 12 minutes

g The least-squares regression line of the number of visitors, y, at a national park and the temperature, x, is modeled by the equation . What is the predicted number of visitors when the temperature is 78o? 10.3 visitors 85.2 visitors 95.5 visitors 888.6 visitors 6,655.9 visitors
Answer: D) 888.6
Step-by-step explanation:
The expression which would help arrive at the required answer is y = 78b + c.
The least regression equation is the equation of best fit obtained from a linear regression graph.
The linear regression equation is expressed in the form :
y = bx + c ; where ;
y = Predicted variable
x = predictor variable
c = intercept
b = slope
The least regression equation is not given in the question above.
However, we could give the equation in the linear regression format :
y = number of visitors
y = number of visitors x = temperature = 78°
Hence, the equation becomes :
y = b(78) + c
y = 78b + c
Inputting the values of b and c in the equation will give the required answer.

The marked angles share a vertex and are formed from opposite rays. They do not share a side, so are not adjacent angles. The angles are vertical angles.
