How many times larger than
(8 + 22) is 8 x (8 + 22)?
Answer:
8
Step-by-step explanation:
8+22 = 30
In order to solve 8 • (8+22), we'll need to use the order of operations. First, complete what is in parenthesis.
8 • (8+22)
30
Then, multiply 30 by 8.
30 • 8 = 240.
So, you can then divide to find your answer. If you divide 240 by 30, you will find that 8 • (8+22) is 8 times larger than 8+22.
Answer:
8 times larger

What is the slope of the line passing through the points (-8,5) and (7,0)
To solve the problem we must know about the slope of a line.
What is a Slope?A slope is also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.
[tex]m = \dfrac{(y_2-y_1)}{(x_2-x_1)}[/tex]
The slope of the line passing through the points (-8,5) and (7,0) is [tex]\dfrac{-1}{3}[/tex].
Given to us
points (-8,5) points (7,0)Points can be written as,
[tex]y_2 = 0\\y_1 = 5\\x_2=7\\x_1 = -8[/tex]
The slope of a lineWe know that the slope of a line whose two points are given is written as,
[tex]m = \dfrac{(y_2-y_1)}{(x_2-x_1)}[/tex]
Substituting the value, we get,
[tex]m = \dfrac{(0-5)}{[7-(-8)]}\\\\m = \dfrac{(0-5)}{[7+8]}\\\\m = \dfrac{(-5)}{[15]}\\\\m= \dfrac{-1}{3}[/tex]
Hence, the slope of the line passing through the points (-8,5) and (7,0) is [tex]\dfrac{-1}{3}[/tex].

The scale of a map says that 6 cm represents 15 km.
What distance on the map represents an actual distance of 6 kilometers?
a) 0 3.6
b) 2.5
c) 0 2.4
d) 0.42
Answer:
Scale distance on map representation = 2.4 cm
Step-by-step explanation:
Given:
Scale factor [6 cm - 15 Km]
Actual distance = 6 km
Find:
Scale distance on map representation
Computation:
Scale distance on map representation = Actual distance[6cm / 15km]
Scale distance on map representation = 6km [6cm / 15km]
Scale distance on map representation = 36 / 15
Scale distance on map representation = 2.4 cm

If∠=2−25&∠=95−,find.
Answer:
Alternate interior angles have the same measure. As we know that 'angle 1 ' and 50° are alternate interior angles hence they must be equal. Also we now that sum of all the angles of a triangle is equal to 180°. Hence, m∠2=15°.
Given the function f(x) = 4x3 + 13x, what is the gradient of the function when x = 2 ?
Answer:
y=45x+115
Step-by-step explanation:
We can find the slope of a line tangent to a curve at a point by evaluating the derivative of the function at that point.
We are given the function
f ( x ) = 4 x 3 + 12 x 2 + 9 x + 7
= f ( x ) = 4 x 3 + 12 x 2 + 9 x 1 + 7 x 0
Using the power rule, let's now compute the derivative of f( x )
f ' ( x ) = ( 3 ⋅ 4 x 2 ) + ( 2 ⋅ 12 x ) + ( 1 ⋅ 9 x 0 ) + 0 ⋅ 7 x − 1
f ' ( x ) = 12 x 2 + 24 x + 9
We can now find the slope of f ( x ) at x = − 3 by substituting this value into f ' ( x )
f ' ( − 3 ) = 12 ( − 3 ) 2 + 24 ( − 3 ) + 9
f'(-3)=12(9)+24(-3)+9
f'(-3)=108-72+9
f'(-3)=45(slope of the tangent line at x = − 3
Now that we have a slope for the tangent line, we need to identify a point on the line.
We know the tangent line touches the function f ( x ) at the point x = − 3 , so let's find the value of f ( x ) at this point:
f(-3)=4(-3)3+12(-3)2+9(-3)+7
f(-3)=4(-27)+12(9)+9(-3)+7
f(-3)=108+108-27+7
f'(-3)=-20
So we know the tangent line goes through the point
(-3,-20)
Finally, we can use the point-slope formula for a line to find the equation of the tangent line.
y=mx+b
To find the value of b , substitute the values we have calculated for the point and slope of the tangent line:
(-20)=(45)(-3)+b
-20=-135+b
b=115
So our final answer for the equation of the tangent line is:
y=45x+115

Vertices A (-1,1) and Vertices B (-4,1) of Square ABCD are shown below. What is the perimeter?
Hint: find the Vertices C and D first, then find the perimeter. A square is the same length all around!
Answer:
12
Step-by-step explanation:
Distance from (-4,1)to (-1,1) =|-4|-|-1|=3
Side of square =3
Since each side of square is equal.
3x4=12
If vertices A (-1,1) and vertices B (-4,1) of Square ABCD then perimeter of the square ABCD is 12 units.
What is Distance?The length along a line or line segment between two points on the line or line segment.
The distance between A and B is 3 units, so the distance between B and C must also be 3 units since the square has equal sides.
The coordinates of C are (-4, -2) since it is directly below B.
The distance between C and D is 5 units since it is a horizontal line between the x-coordinates of C and D.
The coordinates of D are (-1, -2) since it is directly to the right of C.
Now we have the coordinates of all four vertices
A (-1,1), B (-4,1), C (-4,-2), and D (-1,-2).
To find the perimeter, we add up the lengths of all four sides:
AB = BC = CD = AD
= √[(xB - xA)² + (yB - yA)²]
= √[(-4 - (-1))² + (1 - 1)²]
= 3
So the perimeter is P = AB + BC + CD + AD
= 3 + 3 + 5 + 3
= 14
Therefore, the perimeter of the square ABCD is 12 units.

Maithali, how many of them (%) speak both the languages?
Given,
Nepali speaker : 80% (Y)
Maithili speaker : 60% (X)
We know that,
Both language speaker = Y -X
Now,
Y- X
= 80- 60
= 20
Therefore, 20% people speak both languages

wind resistance varies jointly as an objects surface area and velocity. if an object traveling at 55 miles per hour with a surface area of 20 square feet experiences a wind resistance of 220 newtons how fast must a car with 55 square feet of surface area travel in order to experience a wind resistance of 275 newtons?
Answer:
25 miles per hour
Step-by-step explanation:
Given
[tex]W = Wind\ resistance[/tex]
[tex]A = Surface\ Area[/tex]
[tex]V = Velocity[/tex]
The joint variation can be represented as:
[tex]W\ \alpha\ A*V[/tex]
Where:
[tex]V = 55; A = 20; W = 220[/tex]
Required
Find V, when: [tex]A = 55; W = 275[/tex]
We have:
[tex]W\ \alpha\ A*V[/tex]
Express as an equation
[tex]W= k *A*V[/tex]
Where k is the constant of variation
Make k the subject
[tex]k = \frac{W}{A*V}[/tex]
When: [tex]V = 55; A = 20; W = 220[/tex]
We have:
[tex]k = \frac{220}{20 *55 }[/tex]
[tex]k = \frac{220}{1100}[/tex]
[tex]k = 0.2[/tex]
When: [tex]A = 55; W = 275[/tex]
We have:
[tex]k = \frac{W}{A*V}[/tex]
Substitute: [tex]A = 55; W = 275[/tex] and [tex]k = 0.2[/tex]
[tex]0.2 = \frac{275}{55 * V}[/tex]
Make V the subject
[tex]V= \frac{275}{55 * 0.2}[/tex]
[tex]V= \frac{275}{11}[/tex]
[tex]V= 25[/tex]
