Which of the following is a factor of x3 + 2x2 - 25x – 50?
Answer:
(x - 5)(x + 2)(x + 5)
Step-by-step explanation:
x³ + 2x² - 25x - 50
x³ + 7x² - 5x² - 35x + 10x - 50
x(x² + 7x + 10) - 5(x² + 7x + 10)
(x - 5)(x² + 7x + 10)
(x - 5)(x² + 2x + 5x + 10)
(x - 5)(x(x + 2) + 5(x + 2))
(x - 5)(x + 2)(x + 5)
determine the equation of the line with slope 3/4 passing through the point 4,0
Answer:
[tex]y = \frac{3}{4}x - 3[/tex]
Step-by-step explanation:
If it has a slope of 3/4, then it will look like this:
[tex]y = \frac{3}{4}x + b[/tex]
If it passes through (4, 0), than y = 0 when x = 4
[tex]y = \frac{3}{4}(4) + b[/tex]
[tex]y = 3 + b[/tex]
[tex]b = -3[/tex]
Therefore, the equation is [tex]y = \frac{3}{4}x - 3[/tex].

Gus has a fish tank that holds 4710 inches^3 of water. He is using a cylinder shaped bucket with a radius of 5 inches and a height of 20 inches to fill the tank.
Answer:
3
Step-by-step explanation:
How many times will Gus need to fill the bucket to completely fill the fish tank if he doesn’t spill a drop? Use 3.14 for pi
Number of times = volume of tank /volume of cylinder
volume of cylinder = πr²h
3.14 x 5² x 20 = 1570
4710 / 1570 = 3 times

Find the volume of this cylinder.
Round to the nearest tenth.
17 ft
8ft
[ ? ) ft3
Enter
Answer:
The answer is 3418.1 ft rounded to the nearest tenth.
Step-by-step explanation:
The total volume of the cylinder can be defined by the Area of circular base * Perpendicular height.
The area of the circular base can be calculated as
[tex]\pi \times {r}^{2} [/tex]
where r is the radius of the circular base, which is 8 ft.
The area of the circular base is
[tex]\pi \times {8}^{2} = 64\pi[/tex]
We also know the height of the cylinder is 17 ft.
Hence, the volume of the cylinder is
[tex]64\pi \times 17 = 1088\pi = 3418.0528...[/tex]
This will be rounded up to 3418.1 with the nearest tenth

Answer:
Perimeter = AB + AC + BC = 26.55 units
Step-by-step explanation:
The perimeter of a triangle is the sum of lengths of all sides.
Here we have a right triangle, right-angled at C
angle B = 46°
AB = 11
We continue to calculate
AC = (11)sin(46°) = 7.91
BC = (11)cos(46°) = 7.64
Perimeter = AB + AC + BC = 26.55 units

A grocery store sells apple and oranges by the pound the cost of the apples is $1.30 the cost of the oranges is $1.84 how much more is the cost for 1 and 1 half pound of oranges than the cost for 1 and 1 half pounds of apples?
Answer:
1.5 pounds of oranges cost $0.81 more than 1.5 pounds of apples
Step-by-step explanation:
1.5 pounds of apples = 1.5 × $1.30 = $1.95
1.5 pounds oforanges = 1.5 × $1.84 = $2.76
$2.76 - $1.95 = $0.81
4x + 8y = 24 y = -1 2 x + 5
Answer:the answer to this is 16x -16y=5.

= 4x+13x+8y-24y=5.
16x - 16y =5.
Helen rented a kayak at the lake. There is a charge of $10 as an initial fee and then $2 an hour for every hour that she uses the kayak. If the total charge is $22 , how many hours did she kayak?
Answer:
She kayaked for 6 hours.
Step-by-step explanation:
If $10 is the initial fee, subtract $22 - $10 = $12.
If it charges $2 per hour, divide $12 by $2 which equals 6 hours.
Answer:
6 hours
Step-by-step explanation:
Cost = fee + charge per hour * number of hours
22 = 10 +2h
Subtract 10 from each side
22-10 = 10+2h-10
12 = 2h
Divide
12/2 = 2h/2
6 = h

Answer:
x< -3
Step-by-step explanation:
- 4x + 6 > 18
Subtract 6 from each side
- 4x + 6-6 > 18-6
- 4x > 12
Divide by -4, remembering to flip the inequality
-4x/-4 < 12/-4
x < -3

A bag contains 9 identical balls out of which 3 are blue, 2 are white and the remaining are red.
If a ball is drawn from the bag what is probability that it is :
1. blue
2.not red.
Answer:
Total number of balls = 9
P(blue) = blue / total = 3/9 = 1/3 or 33.33%P(not red) = (total - red)/total = 5/9 or 55.55%The sum of three numbers is 103. The second number is 5 less than the first. The third number is 4 times the first. What are the numbers?
Answer:
The numbers are 18, 13, and 72.
Step-by-step explanation:
Let the three numbers be represented by a, b, and c.
The sum of the three is 103. Thus, we can write that:
[tex]a+b+c=103[/tex]
The second number is five less than the first. So:
[tex]b=a-5[/tex]
And the third number is four times the first. So:
[tex]c=4a[/tex]
Substitute:
[tex]a+(a-5)+(4a)=103[/tex]
Solve for a. Combine like terms:
[tex]6a-5=103[/tex]
Add five to both sides:
[tex]6a=108[/tex]
And divide both sides by six. Therefore:
[tex]a=18[/tex]
So, the first number is 18.
Since the second number is five less than the first, the second number is 13.
And since the third number is four times the first, the third number is 72.
2 intersecting lines are shown. A line with points T, R, W intersects a line with points S, R, V at point R. Angle T R V is 95 degrees. mAngle SRW = °
Answer:
m<SRW = 95degrees
Step-by-step explanation:
If a line with points T, R, W intersects a line with points S, R, V at point R with the point of intersection at R, this means that;
m<TRV = m<SRW (vertically opposite angles)
Since m<TRV = 95 degrees, hence <SRW = 95degrees
Consider the algebraic expression:
−z − 7y + 18x + 4
Which of the following is a constant in this expression?
Which of the following lists all the coefficients in this expression?
Answer:
constant: 4
coefficent: 7, 18 (However, -1 can also be counted as a coefficient, it is just invisible!)
Step-by-step explanation:
coefficient: a numerical or constant quantity placed before and multiplying the variable in an algebraic expression
therefore, 7 and 18 are coefficients. HOWEVER, -1 can also be a coefficient to -z.
constant: a quantity or parameter that does not change its value whatever the value of the variables, under a given set of conditions.
therefore, 4 is a constant.
