Step-by-step explanation:
How much longer does it take a automoblie to travel one mile at 20 miles per hour than at 30 miles per hour? show your work.
a. 1 minute
b. 10 minutes
c. 20 minutes
d. none of these answers.
Answer:
A
Step-by-step explanation:
At the rate of 20 miles per hour, the car will travel 20 miles every 60 minutes, or a third of a mile every minute. This means that it will travel a mile in 3 minutes. For the car travelling at 30 miles per hour, it will travel half a mile every minute, or a mile every 2 minutes. 3-2=1 minute, or choice A. Hope this helps!
What is the value for y?
Enter your answer in the box.
Answer:
y = 14
Step-by-step explanation:
The sum of the angles in a triangle add to 180 degrees
50 + 2x+ 5y + 10 = 180
We know that 2x = 50 since they are the base angles of sides that have the same length, they must be the same
50 + 50 + 5y+10 =180
Combine like terms
110 + 5y =180
Subtract 110 from each side
110+5y-110 = 180-110
5y = 70
Divide each side by 5
5y/5 =70/5
y = 14
A Pyramid has a square base with side s. The height of the pyramid is 2/3 that of its side. What is the expression for the volume of the pyramid?
Answer:
correct choice is option d [tex]v=2/9*s^3[/tex]
Step-by-step explanation:
volume of pyramid is given by 1/3(Area of base* height)
Given base of pyramid is square with length of each side s
area of square is given by [tex]side^2[/tex]
Thus, area of base of pyramid = [tex]s^2[/tex]
Height of pyramid = 2/3 of side of base of pyramid = 2/3* s = 2s/3
Therefore volume of pyramid = 1/3(area of base of pyramid *Height of pyramid)
= [tex]1/3(s^2*2s/3)[/tex]
= [tex]2/9*s^3[/tex]
Thus, correct choice is option d [tex]v=2/9*s^3[/tex]
Answer:
Option D
Step-by-step explanation:
[tex]v=\frac{2}{9} s^{3}[/tex]

A line passes through the point (9, 4) and has a slope of
4 over 3
Write an equation in slope-intercept form for this line.
Answer: y = 4/3x-9
Step-by-step explanation:
We just need to find the y-intercept, b. Recall that y-intercept form is y=mx+b. Plug in what we have. y=-4, m= 4/3, x=-9.
4= 4/3(9)+b
4=13+b
-9=b
now rewrite the equation with b now. y= 4/3x-9

In mathematics, the term which is being divided is called a dividend. The term by which the dividend is getting divided is called a divisor. The quotient is the term we get after dividing the dividend by a divisor.
Here in this case, the dividend is written.
-x² x x
which in the equation form is written as
-x² + x + x
add the x terms to simplify
-x² + 2x
The divisor is given as x, divide the equation by x:
(-x² + 2x)/x
(-x²/x) + (2x/x)
-x+2

Which equation, when graphed with the given equation, will form a system that has no solution? A)y = 3 x + 6 B)y = negative 3 (x + 6) C)y = negative 3 (x minus 2) D)y = 3 (x minus 2).
Answer:
y = -3 (x + 6) when graphed with the given equation, will form a system that has no solution
Step-by-step explanation:
Given line equation: [tex]y=-3x+6[/tex]
We are supposed to find Which equation, when graphed with the given equation, will form a system that has no solution.
We know that a system of two linear equations has no solution if and only if the two equations have the same slope, but not the same y-intercept.
General equation of line = [tex]y=mx+c[/tex]
A)y = 3 x + 6
So, Slope = 3
B)y = -3 (x + 6)
y=-3x-18
So, slope=-3
C)y=-3(x-2)
y=-3x+6
So, Slope = -3
D)y=3(x-2)
Slope =3
So, B has the same slope but different intercept
So,y = -3 (x + 6) when graphed with the given equation, will form a system that has no solution
Answer:
B) y= -3(x+6)

The arc length covered by the central angle equal to 72° is 12.56°
What are arc length?Arc length is the distance between two points along a section of a curve.
Given that, a circle with radius 10 units and a central angle equals 72°, we need to find the arc length covered by the central angle = 72°
We know that,
Arc length = 2π × radius × (θ / 360°), where θ is the central angle
Arc length = 2 × 3.14 × 10 × 72°/360°
= 12.56°
Hence, the arc length covered by the central angle equal 72° is 12.56°

The following blueprint of a kitchen has dimensions of 8 inches by 8 inches. The island has been highlighted in red.
The island's actual dimensions are feet by feet. If the scale of the blueprint is 1 inch = feet, what are the dimensions of the island on the blueprint?
Answer:
so assuming 1 3/4 feet by feet means 1 3/4 feet by 1 foot,
island actual dimentions=1 3/4 feet by 1 foot
scale=1 inch=1 feet
logically, blueprints are smaller so for every real foot, 1 inch is drawn on the scale
so change every foot to inch
so the island on the blueprint=1 3/4 inch by 1 inch

this is for 7 not 8 just switch up the numbers

Number of days purchase all possible ticket is 292,201,338
Given:
Number of white ball selected = 5
Total number of ball = 69
Number of red ball = 26
Find:
Number of days purchase all possible ticket
Computation:
Number of days purchase all possible ticket = ⁶⁹C₅ × ²⁶C₁
Number of days purchase all possible ticket = [69! / (5!64!)]26
Number of days purchase all possible ticket = [69 × 68 × 67 × 66 × 65 × 26] / [5 × 4 × 3 × 2 × 1]

find the area of the isosceles triangle
Answer:
60
Step-by-step explanation:
→Before you use the formula to find the area of the isosceles triangle, you must find the height, and to do this, you can use the Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex]
→We are given the hypotenuse, "c," as 13, and the leg is 5 (we split the base of 10 in half).
[tex]5^2+b^2=13^2[/tex]
[tex]25+b^2=169[/tex]
→Subtract 25 from both sides:
[tex]b^2=144[/tex]
→To get "b," by itself, take the square root of both sides:
[tex]\sqrt{b^2} =\sqrt{144}[/tex]
[tex]b = 12[/tex]
→Formula for area:
A = [tex]\frac{bh}{2}[/tex]
A = [tex]\frac{(10)(12)}{2}[/tex]
A = 60
The area of the isosceles triangle is 60 square units.
What is an area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the triangle in a two-dimensional plane is called the area of the triangle.
The area is calculated by having the height of the triangle and the base of the triangle.
The height is calculated by using the Pythagorean theorem.
H² = P² + B²
13² = P² + 5²
P² = 169 - 25 = 144
P = √144 = 12 units
The perpendicular is the height of the triangle.
The area is calculated as:-
A = ( 1 / 2 ) x B x H
A = ( 1 / 2 ) x 10 x 12
A = 60 square units.

The required volume of the given cylinder is 2260.8 cubic centimeters.
What is the volume of a cylinder?The volume of a cylinder is equal to the product of the area of the circular base and the height of a cylinder. The volume of a cylinder is defined as the space occupied by the cylinder as the volume of any three-dimensional shape is the space occupied by it
V = πr²h
where 'r' is the radius of the base (circle) of the cylinder
'h' is the height of the cylinder
As per the given question, we have data as:
Radius(r) = 6 cm
Height(h) = 20 cm
Volume of cylinder = πr²h
Volume of cylinder = 3.14 × (6)² × 20
Volume of cylinder = 3.14 × 36 × 20
Volume of cylinder = 2260.8 cm³
Thus, the required volume of the given cylinder is 2260.8 cubic centimeters.
