32 less than 3/7 of a number is 11/35 of that number. Find the number.
Answer:
Step-by-step explanation:
Let "a number" be x.
"3/7 of a number" means (3/7)x
"32 less" means - 32
Thus, "32 less than 3/7 of a number" means (3/7)x -32
"is 11/35 of that number" means = (11/35)x
Put these together and we get:
(3/7)x -32 = (11/35)x
(3/7)x - (11/35)x = 32 Rearrang to get the x on one side
We need to change "(3/7)x - (11/35)" so that the two terms have a common denominator.
If we multiply the first term by (5/5) [which is equal to 1], we get:
(5/5)(3/7)x or
(15/35)x
We can now write:
(15/35)x - (11/35)x = 32
(4/35)x = 32
Multiply both sides by (35/4)
(35/4)(4/35)x = (35/4)(32)
x = (35)(8)
x = 280

Answer:
A. y<-1/5x+1
Step-by-step explanation:
First, find the slope of the line
delta y / delta x = slope (delta means "change in", so delta y would the the change in y)
the change in y is 1, and the change in x is -5, so the slope is -1/5
we now know that the equation of the line is
y=-1/5x+1
The answer can't be c or d, because the line is dotted and not solid (solid lines signify ≥ or ≤, and dotted > and <)
To test if it is > or <, we can plug in some numbers to see if the equation is true
Right now, we have:
y[?]-1/5x+1, where "[?]" is either > or <
we see that the point 0,0 is a solution, since it is in the shaded region of the graph, because of this, we know that if we plug x=0 and y=0 into the equation, it must be true
plug in:
0[?]-(1/5)*0+1
0[?]1
clearly, [?] should be <, as 0<1
so, now that we know [?], we can replace it in our equation
y<-1/5x+1 , or "A"

Step-by-step explanation:
Hi!
These are supplementary angles, which means they both add up to 180°
Therefore,
9x+10 + 1x + 20 = 180
to solve, combine like terms
10x + 30 = 180
Then subtract 30 from both sides
10x = 150
now divide 10 from both sides leaving x by itself

An inverse variation function has a k value of 8. Which ordered pair is on the graph of the function?
The points on the graph of the inverse variation are of the form:
(x, 8/x)
Which ordered pairs are on the graph of the function?An inverse variation function is written as:
y = k/x.
Here we know that k = 8.
y = 8/x
Then the points (x, y) on the graph of the function are of the form:
(x, 8/x).
So evaluating in different values of x, we can get different points on the graph:
if x = 1, the point is (1, 8)if x = 2, the point is (2, 4)if x = 3, the point is (3, 8/3)if x = 4, the point is (4, 2)And so on.

Hence:
y = a(x + 40)(x - 50)
It includes the point (-55,-75), hence:
-75 = a(-55 + 40)(-55 - 50)
a = 75/(15 x 105)

Step-by-step explanation:
At a certain fast-food restaurant, 56% of customers order a chicken sandwich, 43% of customers order french fries, and 30% of customers order both a chicken sandwich and french fries. What is the probability that a randomly selected customer will order a chicken sandwich or french fries (or both items)?
The probability that a randomly selected customer will order a chicken sandwich or french fries is 36%
How to determine the probability?
The given parameters are:
P(Chicken) = 56%
P(Sandwich) = 43%
P(Both) = 30%
The required probability is:
P = P(Chicken) + P(Sandwich) - P(Both)
This gives
P = 56% + 43% - 30%
Evaluate
P = 36%
Hence, the probability that a randomly selected customer will order a chicken sandwich or french fries is 36%

A particle is moving along a projectile path at an initial height of 80 feet with an initial speed of 112 feet per second. this can be represented by the function h(t) = −16t2 112t 80. what is the maximum height of the particle?
Answer:
276 feet
Step-by-step explanation:
The best way to do this is to complete the square, which puts the quadratic in vertex form. The vertex of a negative parabola, which is what this is, is the highest point of the function...the max value. The k coordinate of the vertex will tell us that highest value. To complete the square, we will first set the quadratic equal to 0, then move the constant over to the other side:
The rule for completing the square is that the leading coefficient must be a positive 1. Ours is a negative 16, so we have to factor out -16:
Now the next thing is to take half the linear term, square it, and then add it to both sides. Our linear term is 7, half of that is 7/2. Squaring 7/2 gives you 49/4. So we add 49/9 into the parenthesis on the left. However, we can't forget that there is a -16 out front there that refuses to be ignored. We have to add then (-16)(49/4) onto the right:
The purpose of this is to create a perfect square binomial that serves as the h value of the vertex (h, k). Stating that perfect square on the left and doing the addition on the right:
Now we finalize by moving the constant back over and setting it back equal to y:
The vertex is
That translates to "at 3.5 seconds the particle is at its max height of 276 feet".

136mm into cm and mm
Step-by-step explanation:
13.6 is the answer because 1cm is 10 cm
Answer:
13.6 cm
Is the second requested unit mm? The value is already in mm.
Step-by-step explanation:
Use conversion factors for the metric system.
By definition: 1cm = 10mm
We can write this as a conversion factor. Either:
1) 1cm/10mm, or
2) 10mm/1cm
We are given 136 mm. Convert that by using either conversion factor.
(136mm)*(1cm/10mm) = 13.6 cm Note how the mm unit cancels.
To use the other conversion factor, do a division:
(136mm)/(10mm/1cm) = 13.6 cm
====
136 mm is already 136 mm.
What is the correct slope-intercept form of the equation y+4=2(x−3)?

the equation of a line in slope- intercept form is

y + 4 = 2(x - 3) ← distribute the parenthesis
y + 4 = 2x - 6 ( subtract 4 from both sides )
y = 2x - 10 ← in slope- intercept form

Answer:
coneradius 8 unitsheight 6 unitsStep-by-step explanation:
The attached image shows the figure of rotation generated by rotating a triangular shape about the x-axis.
ShapeWhen the given line is rotated about the x-axis, each point on the line traces a circle in the y-z plane. Those together will make a cone shape. The radius of the circle is the distance of the point from the x-axis.
DimensionsThe base of the cone will be the circle obtained by rotating the y-intercept about the x-axis. As above, the radius of that circular base is the y-value of the y-intercept: 8 units.
The height of the cone will be the x-value of the point where the radius is zero, at x=6.
The cone has a height of 6 units and a radius of 8 units.
