Reduce fractions to their lowest terms equivalents
Multiply the numerators and denominators of the fractions separately
[tex]\frac{7}{15}[/tex] * 120 = convert to fraction
[tex]\frac{7}{15}[/tex] * [tex]\frac{120}{1}[/tex] = convert to fraction
[tex]\frac{7 * 120}{15}[/tex] = apply fraction rule [tex]\frac{a}{b}[/tex] * [tex]\frac{c}{d}[/tex] = [tex]\frac{a * c}{b * d}[/tex]
[tex]\frac{7 * 120}{15 *1}[/tex] = apply rule a * 1 = a 15 * 1 = 15
[tex]\frac{120}{15}[/tex] = 8 divide the numbers
7 * 8 = 56 multiply the numbers

Josef has $300 to spend. Which inequality could help him find the maximum number of gifts, x, he could buy if he needs $215 to fix his car and then wants to spend $15 on each gift?
Answer:
x = (300 - 215)/15
Step-by-step explanation:
x, the amount of gifts, is equal to the amount of money left over after he fixes his car, divided by the amount he's willing to spend on each gift.
josef could buy a maximum of 5 gifts! the answer is 5.6 but he can't buy half a gift, nor can he afford 6, so we round down to get 5 gifts :)
Answer:
Josef can buy 5 gifts for 75$
Two angles are supplementary. One angle measures 52 degrees more than the other angle. Find the measure of the LARGER angle.
[tex]\begin{array}{l}\text{We\ have\ } \alpha +\beta =180\ \text{and} \ \beta =\alpha +52\text{\ then}\\\\\alpha +\alpha +52=180\\\\\Longrightarrow 2\alpha =180-52\\\\\Longrightarrow \alpha =\frac{128}{2} =64\\\\\therefore \beta =64+52=116\\\\\therefore \boxed{\text{The\ larger\ angle\ is\ 116\ degrees}}\end{array}[/tex]
Solve the inequality and graph the solution on the line provided.
7 + 5x < 42
Answer:
x < 7
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
5x+7<42
Step 2: Subtract 7 from both sides.
5x+7−7<42−7
5x<35
Step 3: Divide both sides by 5.
x<7
For the graph, draw an open circle at 7 and an arrow pointing left.
Hope this helps! :D
Step-by-step explanation:
5x<42-7
5x<35
5x/5<35/5
x<7
if Angle 1 and angle 2 are complementary, angle 1 = (6.c + 3) and angle 2 = (4x + 7) , what does angle 2 =?
39
60
8
51
Answer:
C
Step-by-step explanation:
They are complementary which means they add to 90. I take it that the c is a typo and you meant x
6x + 3 + 4x + 7 = 90 Combine like terms.
10x + 10 = 90 Subtract 10 from both sides
10x = 90 - 10
10x = 80 Divide by 20
x = 80/10
x = 8

I need help with number 3 plzzz fast
Step-by-step explanation:
the domain is the interval of the x (input) values.
in other words, is g(x) invalid for certain x ?
it does not look like it. it looks like g(x) is valid for every possible value of x from -infinite to +infinite.
the range is the interval of possible y (functional) values.
and that is clearly valid for every y between -1 and +infinity.

Step-by-step explanation:
We are going to use the following properties of logarithms to solve this problem:
[tex]\log{\dfrac{a}{b}} = \log{a} - \log{b}[/tex]
and
[tex]\log{ab} = \log{a} + \log{b}[/tex]
So we can rewrite the given equation as
[tex]\log{2x^3} - \log{x} = \log{\left(\dfrac{2x^3}{x}\right)} = \log{2x^2}[/tex]
Also,
[tex]\log{16} + \log{x} = \log{(16x)}[/tex]
So we can write
[tex]\log{2x^2} = \log{(16x)}[/tex]
or eliminating the log symbols, we get
[tex]2x^2 = 16x[/tex]
The solutions for the equation above are
[tex]x = 8\:\text{and}\: 0[/tex]

A cab company charges $3 per cab ride,
plus an additional $2 per mile driven. How
long is a cab ride that costs $11?
miles
Answer:
The answer is c = 2 + 3d .
Step-by-step explanation:
It is given that a cab ride cost $2 which is a fixed amount and charges additional $3 per mile. So you have to make an equation of c in terms of d :
Let c be the cost,
Let d be the distance,
c = 2 + 3d

Answer:
Total Number of times Spun = 1200
Key sentence: "Pr(Red) is same as Pr(Yellow).
Pr(Green)= 0.2
0.2 = x/1200
x= 0.2 x 1200
x = 240.
It landed on green 240 times
Pr(Brown) =0.54
0.54 = y/1200
y= 1200 x 0.54
y= 648.
Now
To get the Number of times it landed on Red and Yellow
You simply subtract that of Green and Brown from 1200 and divide this result by 2(Since Red and Yellow are have equal occurrence).
1200 – (648 + 240)
= 312.
312/2 = 156.
So It landed on Red and Yellow 156 times each.
Step-by-step explanation:
Red ----- 156times
Green -----240times
Brown ----- 648times
Yellow -----156times

Answer:
below
Step-by-step explanation:
1 corn equals 700-800 the yellow tiny thing.
so, lets just assume it has 700,
therefore, 700 - 6 = 694
694 + 1 = 695.
or 700 + 1 = 701.
or perhaps
800 - 6 = 794
794 + 1 = 795
or 800 + 1 = 801
but then again it depends on how much the yellow tiny thing is on the corn. bc, it could be 705, 807, or even 900, who knows.
A calculator which was bought for Rs.450,was sold at Rs.495.What was the gain percent?
Answer:
10%
Step-by-step explanation:
495-450=45
45x100/450=10
Answer:
Profit made by reselling = 495 - 450 = ₹45
So, percentage =
[tex] \frac{45}{450} \times 100 = 10\%[/tex]
So, gain percentage is 10%

tan 205
sin 25°
cos 65
cos 245
9514 1404 393
Answer:
tan(205°) = asin(25°) = (a√(a²+1))/(a²+1)cos(65°) = (a√(a²+1))/(a²+1)cos(245°) = -(a√(a²+1))/(a²+1)Step-by-step explanation:
The tangent function is periodic with a period of 180°. So ...
tan(205°) = tan(25°) = a
__
The identity relating sine and tangent is ...
sin(x) = tan(x)/√(tan²(x)+1)
Rationalizing the denominator gives ...
sin(x) = tan(x)√(tan²(x)+1)/(tan²(x)+1)
sin(25°) = a√(a²+1)/(a²+1)
__
cos(65°) = sin(25°) = a√(a²+1)/(a²+1)
__
cos(245°) = -sin(25°) = -a√(a²+1)/(a²+1)
