Step-by-step explanation:
Here, we need to use the concept of the FOIL method
First Outer Inner Last----------------------------------------------------------
Given
(-3y+1)(4y²-y-7)
Expand Parenthesis using FOIL
-12y³+3y²+21y+4y²-y-7
Put like terms together

You finally got promoted to the next grade level. You and your friends go out to celebrate your success at Chuck E Cheeses. The total meal cost $70. There is a 15% tip with the meal. Which expression can you use to calculate the total cost of the meal with tip?
A. 0.15 (70)
B. 1.5 (70)
C. 1.15 (70)
D.11.5 (70)
Answer:
80 dollars and 50 cents.
Step-by-step explanation:
youd first multiply 70 by .15 which would equal 10.5. then add the 70 and 10.5 together. then you get your answer. so the expression youd want to use would be "x=70×.15"
The perimeter of a rectangular chicken coop is 30 feet. the width is w feets and the length is w + 4 feet. what is the length and width of the coop
The width and length of the chicken coop are 5.5 feet and 9.5 feet respectively.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
The perimeter of a rectangle is given by P = 2L + 2W, where L is the length, W is the width and P is the perimeter.
We know that the width is w feet and the length is w+4 feet.
Given that the perimeter of the chicken coop is 30 feet, we can set up the following equation:
30 = 2(w + 4) + 2w
We can simplify this equation by combining like terms:
30 = 2w + 8 + 2w
30 = 4w + 8
22 = 4w
w = 5.5
So the width of the coop is 5.5 feet.
To find the length of the coop, we can use the information that the width is 5.5 feet and the length is w+4 feet.
The length of the coop is 5.5 + 4 = 9.5 feet

What is the equation of the line that is parallel to the line 6x+3y=4 and has a y-intercept of −6?
Answer:
y=-2x-6
Step-by-step explanation:
Slope intercept form of a line: y=mx+b (m is the slope and b is the y-intercept)
Convert our given line 6x+3y=4 into slope-intercept form to find the slope
Subtract 6x on both sides
3y=-6x+4
Divide 3 on both sides
y=-2x+4/3
The slope of the given line is the coefficient of x, -2
Parallel lines have the same slope, so the equation we're solving for also has a slope of -2
We also know that the y-intercept is -6, so we now have all the info we need to make the equation:
y=-2x-6

In circle T with m∠STU=78 and ST=8 , find the length of arc SU. Round to the nearest hundredth.
Answer:
10.89
Step-by-step explanation:
The length of the arc SU in the circle T is 10.88 units.
What is circle?A circle is a shape or a curve in a plane that has a fixed distance, called the radius, from a given point, called the centre.
Given that, in a circle T, m ∠STU = 78° and ST = 8, we need to find the length of arc SU,
The length of an arc = central angle / 360° × perimeter
= 78° / 360° × 3.14 × 16
= 10.88
Hence, the length of the arc SU in the circle T is 10.88 units.

Write 174% as a fraction in simplest form.
Answer:
The answer should be [tex]\frac{87}{50}[/tex]
Step-by-step explanation:
1.74 = [tex]\frac{174}{100}[/tex] = [tex]\frac{87}{50}[/tex]
Answer:
174% = 87/50 = 1 37/50 as a fraction
Step-by-step explanation:
174% = 174/100
Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(174,100) = 2. So,
(174÷2)/(100÷2) = 87/50 when reduced to the simplest form.
As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 174/100 is also equal to 1 37/50 when expressed as a mixed number.

find the common denominator
the common denominator is 35
so since you multiply 7 to 5 to get 35 multiply 7 to 3
3/5 = 21/35
since you multiply 5 to 7 to get 35 multiply 5 to 4
4/7 = 20/35

Ann has $ 1, $10, and $20 bills. She has 4 times as many $20 bills as $10 bills. She has 3 times as many $1 bills as $20 bills. She has a total of $204 . Drag and drop the number of $1, $10, and $ 20 bills she has.
Answer:
Ann has 24 $1 bills, 2 $10 bills, and 8 $20 bills.
Step-by-step explanation:
Given that Ann has $1, $10, and $20 bills, and she has 4 times as many $20 bills as $10 bills and 3 times as many $1 bills as $20 bills, taking a total of $204, to determine the number of $1, $10, and $20 bills she has, she needs to perform the following calculation:
1 = 3x20 = 3x4x10 = 12x10
20 = 4x10
10 = 10
(12 x 1) + (4 x 20) + 10 = 12 + 80 + 10 = 102
(24 x 1) + (8 x 20) + (2 x 10) = 24 + 160 + 20 = 204
So Ann has 24 $1 bills, 2 $10 bills, and 8 $20 bills.

Let us first resolve the given numbers into prime factors.
By prime factorization,
[tex] \longmapsto [/tex] √8 = √( 2 × 2 × 2)
[tex] \longmapsto [/tex] √8 = 2√2
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
[tex] \longmapsto [/tex] √98 = √( 2 × 7 × 7)
[tex] \longmapsto [/tex] √98 = 7√2
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
[tex] \longmapsto [/tex] √32 = √( 2 × 2 × 2 × 2 × 2)
[tex] \longmapsto [/tex] √32 = 2 × 2√2
[tex] \longmapsto [/tex] √32 = 4√2
According to the question,
[tex] \longmapsto [/tex] √8+√98+√32
[tex] \longmapsto [/tex] 2√2 + 7√2 + 4√2
Taking √2 as common.[tex] \longmapsto [/tex] √2(2 + 7 + 4)
[tex] \longmapsto [/tex] √2(13)
[tex] \longmapsto [/tex] 13√2
So, we get that :
