Answer:
Step-by-step explanation:
The perpendicular is equal to 6. That's because the left triangle's missing angle is 180 - 45 -90 = 45
The angle in the right triangle is given as 52.
The cos(52) = adjacent side (which we just found to be 6) / y
Multiply both sides by y
y cos(52) = 6
cos(52) = 0.6157
Divide by sides by cos(52)
y = 6 / cos(52)
y = 6 / 0.6157
y = 9.76

Answers
Answer:
h(x) = 7x - 3
Step-by-step explanation:
f(x) = 4x − 1 and g(x) = −3x + 2
h(x) = f(x) - g(x)
h(x) = 4x - 1 - (-3x + 2)
h(x) = 4x - 1 + 3x - 2
h(x) = 7x - 3

Allison has 10 coins in dimes and nickels in her purse. The value of the coins is $0.70. Which pair of equations can be used to find the number of dimes, d, and nickels, n, Allison has in her purse?
Answers
Answer:
A lot
Step-by-step explanation:
Does this girl not have a credit card
The pair of equations is d + n = 10 and d + 5 n = 7 that can be used to find the number of dimes and nickels.
What is an equation ?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Given that,
Number of dimes = d
And number of nickels = n.
Total number of coins = 10.
Also, the value of coins = $0.70.
According to given conditions,
Since, Total number of coins is 10,
The equation can be written as,
d + n = 10
Total value of coins are = 0.70
0.1d + 0.05n = 0.70
1/10 d / 5n / 100 = 0.70
10 d + 50 n = 70
d + 5 n = 7
The required pair of equations are d + n = 10 and d + 5 n = 7.

Mae buys 7 boxes of drinks. The cost of each box of drinks is £7 and each box holds 12 cans.She sells 3/4 of the total number of cans for 70p each and the remaining cans for 40p each. WORK OUT THE TOTAL OF PROFIT HE MAKES
Answers
Answer:
£3.50
Step-by-step explanation:
The total number of cans Mae bought was ...
(12 cans/box)×(7 boxes) = 84 cans
The revenue from sales is ...
(3/4)(84)(70p) +(1/4)(84)(40p) = 84(3/4×70p +1/4×40p) = 84(52.5p +10p)
= £52.50
The cost of the drinks was ...
(£7/box)×(7 boxes) = £49.00
Mae's profit is the difference between her sales revenue and her cost:
profit = revenue - cost
profit = £52.50 -49.00 = £3.50

A rectangle has a length of 4 mm has an area is 44 mm² width of the rectangle is
Answers
Answer:
11
Step-by-step explanation:
The formula for area is l * w = a (length * width = area)
4 is our length, and 44 is the area, so the equation turns to this:
4 * x = 44
To solve for x, just divide 44 by 4.
44 / 4 = 11.
Now we enter that into our equation so it looks like this:
4 mm * 11 mm = 44 mm^2.

-7.5x -12.5, x < -17.5x +2.5, x ≥ -1Step-by-step explanation:
The absolute value function changes slope at its vertex. Here, that vertex is translated to x = -1. To the left of that point, the function is equivalent to one that negates its argument:
|x| = -x . . . for x < 0
|x| = x . . . for x ≥ 0
for (x+1) < 0
y = -7.5(x +1) -5 = -7.5x -12.5
for (x+1) ≥ 0
y = 7.5(x +1) -5 = 7.5x +2.5
This means we can write the piecewise function as ...
[tex]y=\begin{cases}-7.5x-12.5,&\text{if }x<-1\\7.5x+2.5,&\text{if }x\ge-1\end{cases}[/tex]

Give your answer correct to 1 decimal place when appropriate.
Answers
Answer:
14%
Step-by-step explanation:
So if we have 4 Year 11 pupils out of a total of 29 pupils at a football club, the fraction for that would be 4/29, if we convert 4/29 into a decimal number we get 0.13793103448, so we round this number up to the nearest 1 decimal place, and that would be 0.14 which equals 14%. Hope this helps.

making the equation -1.3=x-(-13.2) turn into -1.3=x+13.2.
so you should automatically know your x is going to have to be negative.
