Which is a factor of x2 + 5x − 24?
Answer:
(x−3)(x+8)
Step-by-step explanation:
The middle number is 5 and the last number is -24.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 5
Multiply together to get -24
Can you think of the two numbers?
Try -3 and 8:
-3+8 = 5
-3*8 = -24
Fill in the blanks in
(x+_)(x+_)
with -3 and 8 to get...
(x-3)(x+8)

First shaded boxes = 4/7
Second shaded boxes = 1 out of 8 boxes are shaded = 1/8
Step-by-step explanation:
1/2x1/4=1/8
7X8=56
59-7=49
First shaded boxes = 4 out of 7 are shaded = 4/7
Second shaded boxes = 1 out of 8 boxes are shaded = 1/8
The fractional part of the game is left [tex]\frac{7}{8}[/tex] , total minutes of playing time 56 mins and playing time are left in the game is 49 mins .
What is fraction?A fraction represents a part of a whole or, more generally, any number of equal parts.
According to the question
Jackson is attending a lacrosse game that is halfway through the first quarter
i.e, Game played = [tex]\frac{1}{2} *\frac{1}{4}[/tex]
Game played = [tex]\frac{1}{8}[/tex]
a) fractional part of the game is left
Game left = 1 - [tex]\frac{1}{8}[/tex] (treated complete game as 1 )
= [tex]\frac{7}{8}[/tex]
b) If 7 minutes of playing time have past,
i.e [tex]\frac{1}{8}[/tex] part of game is completed in 7 mins
therefore,
1 whole will complete in 7*8 = 56 mins
c) Minutes of playing time are left in the game
As,
total time to complete the game - game played time
= 56 - 7
= 49 mins
as in the fraction of shading question
a) [tex]\frac{4}{7 } is shaded[/tex]
b) [tex]\frac{1}{8}[/tex] is shaded
Hence , the fractional part of the game is left [tex]\frac{7}{8}[/tex] , total minutes of playing time 56 mins and playing time are left in the game is 49 mins .

The volume of a soup can with height of 6 cm and diameter of 4.4 cm = ____________ cm3. Use 3.14 for pi.
Answer:
about 91.2 cm³
Step-by-step explanation:
Radius (r) = diameter / 2 = 4.4 / 2 = 2.2
Volume of cylinder = πr²h, we know π = 3.14, r = 2.2 and h = 6
V = 3.14 * 2.2² * 6 = 91.2
Answer:
91.2
Step-by-step explanation:
To find the volume you need to use the formula [tex]\pi r^2h[/tex]
When you substitute all of the numbers the answer will be 91.1856
13. If 16 people are needed to run 7 machines, how many people are needed to run 35 machines?
Answer:
80
Step-by-step explanation:
16 people =7
7*5= 16*5
35=80 people
Answer:
80 people are required to run 35 machines
Step-by-step explanation:
Write and solve an equation of ratios:
p 35
------- = -----
16 7
where p is the number of people needed to run 35 machines.
Cross-multiplying yields 7p = 16(35), or p = 16(5), or p = 80
80 people are required to run 35 machines.
Find the angle between the given vectors to the nearest tenth of a
degree.
U = 13i - 8j V = 2i + 9j
Answer: 109.1 degrees
Step-by-step explanation:
To find the angle between the given vectors, we will use the formula below:
Cos(θ) = (U.V)/ |U|.|V|
Where
U = 13i - 8j
V = 2i + 9j
U.V = (2x13) + (-8×9)
U.V = 26 - 72
U.V = - 46
|U| = sqrt ( 13^2 + 8^2)
= sqrt ( 233) = 15.264
|V| = sqrt( 2^2 + 9^2)
= sqrt ( 85 ) = 9.22
Substitute all the value of the parameters into the formula
Cos ø = -46 / (15.3 × 9.2)
Cos ø = - 46 / 140.72
Cos Ø = - 32687
Find the cos inverse of the value
Ø = cos^-1( -32687)
Ø = 109.079 degrees
Therefore, the angle between the given vectors to the nearest tenth of a degree is 109.1 degrees

Total surface = surface area of the base square + area of 4 triangles
Calculate the surface area of the base square
surface area of the square = s^2
where s= side length
s=3 in
The surface area of the base =s^2
=3^2
= 9 square inches
The surface area of the side triangles
The area of the triangle = (1/2)* side length* slant height
Side length=3 in
Slant height=6 in
substituting the values,
The area of the triangle =1/2*3*6
= 18/2
= 9 square inches
There are 4 triangles
The area of 4 triangles = 4 x 9
= 36 square inches
Therefore,
Total surface = surface area of the base square + area of 4 triangles
= 9 + 36
= 45 square inches

If the trapezoid is reflected over the line segment BC, what will be the new coordinates of point A?
Answer:
(13,15)
Step-by-step explanation:
If the trapezoid were to be reflected over the line segment BC, the new coordinates of point A would be (13,15) as it moves to right 5 points from BC sides.
Answer:
(B) 13,15
Step-by-step explanation:
If we look at point A in relation to point B, we see that it's 5 units to the left and 3 units down from point B, therefore making it at (3,15). Now, if we reflect across line BC (which is a y-axis) then we change the X value, not the y value. If the line BC is located at X=8, then the X value will be 8+5, since point A is 5 units away from the line BC. The y value will stay the same because we are reflecting over only one axis. 8+5 = 13, and the y stays at 15, so the new point value of A would be (13,15).

Answer:
{y = 1/4x^2 − 2 y = −1/2x}
(0,0)
(-6,3)
Step-by-step explanation:
Rewrite as system of equations
y=-1/2x
1/4x^2-2y=-1/2x
Move expression to left and change its sign
y+1/2=0
1/4x^2-2y+1/2x=0
Multiply both sides of equation by 2
2y+x=0
1/4x^2-2y+1/2x=0
Sum the equation vertically and eliminate variable (2y)
3/2x+1/4x^2=0
Solve the equation
x=0
x=-6
Substitute the value of x into equation
y+1/2*0 = 0
y+1/2*(-6) = 0
Solve equation for y
y=0
y=3
so the solution is
(x1,y1)=(0,0)
(x2,y2)=(-6,3)

PLZ I WILL GIVE BRAINLIEST AND IT HAS 20 POINTS The volume of a cylinder is approximately 72 feet cubed. Which is the best approximation of the volume of a cone with the same base and height as the cylinder? 24 feet cubed 216 feet cubed 24 pi feet cubed 216 pi feet cubed
Answer:
24 feet cubed
Step-by-step explanation:
When comparing the volume formula for a cone and the volume formula for a cylinder, a cone is 1/3 of a cylinder. Therefore, divide 72 by 3 to get the volume of a cone with the same base and height. It would not be 24 pi feet cubed because 72 feet cubed is already multiplied by the pi.
Answer:
24 feet cubed
Step-by-step explanation:
Volume formula:
V cylinder = BhV cone = 1/3BhThe ratio:
V cylinder / V cone = Bh ÷ 1/3BhV cylinder / V cone = 3 ÷ 1Plugging in the value of cylinder to find the value of cone:
72 ÷ x = 3 ÷ 1x= 72 ÷ 3x= 24 ft³24 feet cubed is the best estimate
Given: XY - tangent to circles k1(P) and k2(O) OX=16, PY=6 and OP=26 Find: XY
Answer:
XY = 24 units
Step-by-step explanation:
First of all, we need to some construction here.
Let us draw a line parallel to XY from point P towards OX, which cuts OX at point Q.
Please refer to the attached figure.
Now, Let us consider triangle OQP which is a right angled triangle, with
Hypotenuse, OP = 26 units
Height, OQ = OX - PY = 16 - 6 = 10 units
Base, PQ = ?
We can use pythagorean theorem here to find the value of PQ.
According to pythagorean theorem:
[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow OP^{2} = PQ^{2} + OQ^{2}\\\Rightarrow 26^{2} = OQ^{2}+10^{2} \\\Rightarrow PQ^{2} = 26^{2}-10^{2} \\\Rightarrow PQ^{2} = 676-100 \\\Rightarrow PQ^{2} = 576\\\Rightarrow PQ= 24\ units[/tex]
Now, we can see that side PQ is equal to side XY.
[tex]\therefore[/tex] XY = 24 units is the answer.

Example: we have a 2 by 3 rectangle with area of 2*3 = 6. If we cut the first dimension in half, then we have a 1 by 3 rectangle that has area 1*3 = 3. The area has decreased. To keep the area the same, we would have to increase the other dimension some specific amount.
The area of the figure decreases when the dimension is decreased
What is the Area of a Rectangle?The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle
Area of Rectangle = Length x Width
Given data ,
Let the figure be represented as ABCD
where ABCD is a rectangle
Now , the measures of the sides of the rectangle be
The length of the rectangle = L
The width of the rectangle = W
And , Area of Rectangle = Length x Width
On simplifying , we get
Area of rectangle = LW
when the dimension of one of the unit is decreased , we get
when L = L/2
Area of rectangle = ( LW) / 2
So , the area of the figure is decreased bu ( 1/2 )
