Answer:
a= 18; b= 48; c= 88. Please note that even half these value work (9, 24, 44) or any multiple of these (9k, 24k, 44k, with k a positive integer)
Step-by-step explanation:
Let's go easy, and pick b to be 6x8, to make things easy for us. Maybe even 6x4 could work, 12x8 will totally work, but this is the simplest choice.
Now on the first proportion [tex]a:48=3:8 \rightarrow 8a = 48\times3 \rightarrow a = 18[/tex]
From the second proportion [tex]48:c=6:11 \rightarrow 6c = 48\times 11 \rightarrow c = 88[/tex]
The group of points {(0, 1), (0, 5), (2, 6), (3, 3)} is not a function, but the group of points {(1, 4), (2, 7), (3, 1), (5, 7)} is a function. What do you notice about the two groups of points? What do you think it means to be a function? plsss help yall i need the answer for a disscussion and this teacher NEVER give anybody an 100% on disscussions so at least get me an 80
Answer:
I notice that the first group of points contain multiple Y Values for the same X. Notice how 0 could be 1 or 5. The second group has a unique Y for every X. A function is a deterministic system where, given a X, it will map exactly one Y value.

The water in a rain barrel weighs 187.48 kilograms. The weight decreases by 22.69 kilograms as some of the water evaporates. Then it increases by 4.62 kilograms as the result of a storm. How much does the water weigh now?
Answer: 169.41
Step-by-step explanation:
first,substract 22.69 from 187.48 then add 4.62
A stunt car drives off a 150m cliff at a speed of 45mph
. How long does it take the stunt car to reach the ground?
Answer:
5.53 seconds.
Step-by-step explanation:
The equation of motion is
d = 4.9t^2 so
150 = .9 t^2
t^2 = 150 / 4.9
t^2 = 30.612
t = 5.53 seconds.
g = a - c , solve for a
Answer:
a = c + g
Step-by-step explanation:
g = a - c
~Add c to both sides
g + c = a
~Reorder
a = c + g

Please help haha imm failing math 5(x−2 2/5)=−5.2
Answer:
x = 1.36
Step-by-step explanation:
5(x - 2 2/5) = -5.2
5(x - 12/5 ) = - 5.2
(x - 12/5) = -5.2 / 5
x - 12/5 = - 1..04
x = -1.04 + 12/5
x = (- 5.20 +12) /5
x = 6.80 / 5
x = 1.36

you need to find how much the output changes for each unit change in the input. (ie from an input change from 5 to 6 the output changes by three units and an input change of 3 (2 - 5 ) units the output changes by 9 units). This will give you the gradient of the equation. then you have to find out the y intercept by finding what the output is when the input is 0. Do this by multiplying the input by the gradient and then subtracting it from that inputs output. This will give you the answer A) 3x

Answer:
Angle A = Angle T
Angle B = Angle U
Angle C = Angle V
Step-by-step explanation:
The order that the angles are listed above shows you which angle in the first triangle corresponds to which angle in the other triangle. It tells you triangle ABC = triangle TUV. Since A and T are both listed first, they are equivalent. Angles B and U are both listed second, so they correspond to each other. And angles C and V are listed last, so they correspond to each other.

Writer the equation of the porabola in vertex form vertex0,3 point 1,-5
Answer:
the desired equation is y = -8x^2 + 3
Step-by-step explanation:
The vertex form of the equation of a parabola is y = a(x - h)^2 + k, where (h, k) is the vertex and (x, y) is another point on the graph of the parabola.
Substitute 1 for x, -5 for y, 0 for h and 3 for k. We obtain:
-5 = a(1 - 0)^2 + 3, or
-5 = a(1) + 3, or -5 = a + 3. Then a must be -5 -3, or a = -8
and the desired equation is y = -8x^2 + 3

Step-by-step explanation:
what is the value of W?
So, Q is the mid-point of UR.
Similarly, UT = TSSo, T is the mid-point of US.
So, QT is parallel to RS and half of it.Given, QT = w and RS = w + 37Therefore, QT = 1/2 RSor, w = 1/2(w + 37)
or, w = w/2 + 37/2
or, w - w/2 = 37/2
or, w/2 = 37/2
or, w = 37/2 × 2
or, w = 37.
Answer:The value of w is 37.

Step-by-step explanation:
Substitute the values into the formula given
What sequence of 5 numbers have a mode of 7, mean of 9 and a median of 8?
There are 4 possible answers and they are:
{7, 7, 8, 8, 15}{7, 7, 8, 9, 14}{7, 7, 8, 10, 13}{7, 7, 8, 11, 12}This is assuming only integers are allowed.
====================================================
Explanation:
The sequence starts off as {A,B,C,D,E}
The median is 8, which is the direct center (slot C).
So we can update the sequence to {A,B,8,D,E}
The mode is 7. The mode is the value that shows up the most frequent compared to the other values. This tells us that the mode must show up at least two times. In this case, it must show up exactly twice because of the A,B values which are smaller than the median 8 in slot C.
So we know that A = 7 and B = 7.
The sequence updates to {7,7,8,D,E} where D and E are not 7.
If either D and/or E were 7, then the list would be {7,7,7,8,x} or {7,7,7,7,8}; however, this would lead to the median not being 8. So this line of reasoning allows us to rule out neither D nor E being 7.
-----------------------
Let's add up those five values, and divide by n = 5, to compute the mean
mean = (A+B+C+D+E)/5
mean = (7+7+8+D+E)/5
mean = (22+D+E)/5
Set this equal to the given mean of 9 and isolate the D+E expression
(22+D+E)/5 = 9
22+D+E = 5*9
22+D+E = 45
D+E = 45-22
D+E = 23
Whatever D and E are, they add to 23.
Assuming D and E are integers, there are a few ways to have D+E result in 23. The further restriction is that neither D nor E can be smaller than 8. Refer to the last section.
Here are all of the integer solutions to D+E = 23 where D and E are 8 or larger.
D = 8 and E = 15D = 9 and E = 14D = 10 and E = 13D = 11 and E = 12D = 12 and E = 11D = 13 and E = 10D = 14 and E = 9D = 15 and E = 8There are 8 items in that list above. We can rule out the bottom half of that list because it repeats the top half (just in reverse order). Also, note how E is smaller than D in those items. We'll assume that D < E.
So we can shorten that list to
D = 8 and E = 15D = 9 and E = 14D = 10 and E = 13D = 11 and E = 12This leads to the four possible answers of:
{7, 7, 8, 8, 15}{7, 7, 8, 9, 14}{7, 7, 8, 10, 13}{7, 7, 8, 11, 12}This is assuming that only integers are allowed. If non-whole values are considered, then we'd have infinitely many possible answers. This is because there are infinitely many solutions to D+E = 23 where D and E aren't restricted to the integer values only.

find x^12 coefficient in the expression of (3x -2/x )^10
Step-by-step explanation:
(3x-2/x)^10
(r+1)th term = 10Cr (3x)^10-r (-2/x)^r
= 10Cr (3)^10-r (-2)^r (x)^10-2r
Let 10-2r = 12
- 2r = 2
r= - 1
The coefficient of x^12
= 10C-1 (3)^11 (-2)^-1
= 10C11 (3)^12 (-1/2)
= (1/11) (3)^12 (-1/2)
= - 1/22 × (3)^12
Marcus builds 2,744 kites for a 14-day summer kite festival.
He plans to give away about the same number of kites each day.
He gives away 492 kites the first two days. Did Marcus stick to his plan?
Use estimation to explain. Show your work.
Solution
Answer:
please use the solution
Step-by-step explanation:
solution: 492÷2=246
2744÷14=196
246≥196
so thus Marcus doesn't stick to his plan because he didn't have the number of kites.
No, Marcus did not stick to his plan.
What is Unit rate?A unit rate means a rate for one of something.
Given that, Marcus builds 2,744 kites for a 14-day summer kite festival.
He plans to give away about the same number of kites each day.
He gives away 492 kites the first two days,
According to his plan, he should sell = 2744/14 = 196
But he sold = 492/2 = 246 each day
Hence, he sold more kites than his planning, so he did not stick to his plan.
