computer cost plus printer cost subtracting his current amount equals the total amount left he needs to pay for both of the appliances.
Answer number 14. It’s very difficult for me and i need some help.
Answer:
1201.2 in (100.1ft)
Step-by-step explanation:
A scale model represents a ratio. All sides must be shrunk or increased based on a constant value. In this case the ratio of the model is 1/13 the size of the original giving us a 1:13 ratio. So each side of your scale model must be multiplied by 13 to find the real value of the side.
First convert all units to inches then divide the width of the real windmill by the width of the scale model (both in inches) you will see the answer is 13. Multiply the inch values of all sides of your model by 13 and this gives you the proportional value of each side of the real windmill in relation to the scale model.

Max went to a shopping mall with $35 in his wallet. He spent two fifths of the money he had in his wallet at the bookstore. How much money, in dollars, did he have left?
$21
$26
$10
$13
Answer:
$21
Step-by-step explanation:
1) Find the amount spent.
"Two fifths" = 2/5
So, he spent 2/5 of 35.
= 2 x 35 / 5
= 70 / 5
= 14
2) Subtract 14 from 35, since 35 is the total amount of money he had.
= 35 - 14
= 21
Answer:
$21
Step-by-step explanation:
Given that:
Max went to a shopping mall with $35 in his wallet.
He spent two fifths of the money he had in his wallet at the bookstore.
To Find:
How much money, in dollars, did he have left?
Solution:
Let the left money that max have = x
Base on the given:
$35-(2/5)×$35=x
⇒ $35-($2×7)=x
⇒ $35-$14=x
⇒ x=$21
Hence, max has $21 left.

Ms. Pearson kept track of student absences versus final average grades in her math dass for one semester, The
data is shown in the table below
The correct statement about the data collected by Ms. Pearson is that there is no association between a student's absences and the final average grades.
When do variables have a linear relationship?The equation that represents a linear relationship is: a + bx
Where x represents the rate of increase. Thus, for linear equations, the functiion increases by a constant term.
Looking at the table, the average final grade does not increase by a constant term.

how do you solve -4 + y = 6 and y= 7x - -6 by substitution?
Answer:
by doing the math
Step-by-step explanation:
do (7x)-(-6) then the other problem and find out witch one is more
Answer:
x=4/7 and y=10
Step-by-step explanation:
To solve for x, we must isolate y in one of the equations to then insert it into the other equation. We can take the first equation, -4 + y = 6, and add 4 to both sides. This gives us y = 4+6, or y = 10. Since y is a variable, we can subsititute 10 into the second equation, y = 7x - (-6), giving us 10 = 7x - (-6). The minus negative six is equal to plus six. This gives us 10 = 7x +6. Now we can solve for x. Subtract 6 from both sides; 4 = 7x. Now to find x, we have to divide both sides by 7. This gives us x = 4/7.

Pythagorean Theorem (Rounding)
Answer:
13.4 :)
Step-by-step explanation:
Pythagorean theorem: a^2 + b^2 = c^2
Now lets solve!!
12^2 + b^2 = 18^2
144 + b^2 = 324
Now we subtract!!
324 - 144 = b^2
180 = b^2
Now we need to find the square root!!
[tex]\sqrt{180}[/tex] = 13.4

How many angles are formed by intersecting roads? Number the angles
Answer:
When two lines intersect and form 4 angles at the intersection, the two angles that are opposite each other are called “opposite angles” or “vertical angles” and these vertical angles are “congruent” – meaning they have the same shape and size.

The second term of an arithmetic sequence is –39. The rule a, - a-1 +12 can be used to find the next term of the
sequence. What is the explicit rule for the arithmetic sequence?
Answer:
a 2 = -39
a 2 = a 1 + 12
- 39 = a 1 + 12
a 1 = - 39 - 12
a 1 = - 51 ( first term )
The common difference is : d = 12
The explicit rule for the arithmetic sequence:
a n = a1 + ( n - 1 ) d
a n = -51 + ( n - 1 ) · 12
