Answer:
=k=0.25h-7/12
Step-by-step explanation:
4(h-3k)=h+7
=4h-12k=h+7
collecting like terms and leaving characters with k on 1 side, we get;
12k=3h-7
=k=0.25h-7/12

21 22 23 24 25 Won has a container with the shape below. A rectangular prism with length of 18 centimeters, width of 10 centimeters, and height of 12 centimeters. A rectangular pyramid has a base of 18 centimeters by 10 centimeters and height of 10 centimeters. Which statements are true about the container? Select three options. The shape can be broken into a rectangular prism and a triangular prism. The shape can be broken into a rectangular prism and a rectangular pyramid. The formula for the volume of this figure is V = B h + one-third B h. The volume of the container is 2,760 centimeters cubed. The volume of the container is 3,060 centimeters cubed.
Answer:
2nd statement
3rd statement
4th statement
Step-by-step explanation:
The 2nd statement we know is true since the container was already described with a rectangular pyramid and a rectangular prism.
The 3rd statement is true since the volume for a rectangular prism is,
V=wlh or V=bh (b=wl)
The volume of a rectangular pyramid is
V=1/3*wlh or V= 1/3*bh (b=wl)
The 4th statement is true since the formula for the volume of this container is V=wlh+wlh/3. So substitute the values of the rectangular prism and rectangular pyramid and,
V=10*18*12+(18*10*10)/3
V=2160+1800/3
V=2160+600
V=2760

Answer:
[tex]f^{-1}[/tex](x) = 0.5x + 2
Step-by-step explanation:
let y = f(x) and rearrange making x the subject , that is
y = 2x - 4 ( add 4 to both sides )
y + 4 = 2x ( divide both sides by 2 )
[tex]\frac{y+4}{2}[/tex] = x
Change y back into terms of x with x = [tex]f^{-1}[/tex] (x)
[tex]f^{-1}[/tex] (x) = [tex]\frac{x+4}{2}[/tex] = 0.5x + 2
Answer: F -1(x) = 0.5 x + 2

Solve for b.
-32 + 10b = -22
Answer: b = 1
Step-by-step explanation:
= -32 + 10b = -22
-32 + 10 = -22
b = 1
Check: -32 + 10(1) = -22
= -22
Answer:
b=1
Step-by-step explanation:
Hello,
We would like to solve for b in the equation -32+10b=-22.
When we want to solve for a variable, we want to isolate it on one side (have it on one side by itself. No other numbers.)
So to start, add 32 to both sides to remove it from the left side (-32+32=0).
-32+10b=-22
+32 +32
______________
10b=10
Now, there isn't anything with 10b, but we want the value of b by itself (1b), as 10b is 10 times the value of what b is.
So divide both sides by 10
b=1

A number is more than half of another number by 4. The difference of these two numbers is 2. Find these numbers.
Answer:
10,12
Step-by-step explanation:
let the two numbers be x and y
difference between x and y is 2
but y is ½x + 4
x -(½x+4) = 2
x - ½x - 4 = 2
½x = 6
x = 12
y = ½x + 4
y = 10
Determine the length ofx and the length ofy, to the nearest tenth of a metre.

a. x = 7.2 m and y= 9.7 m
b. x = 9.6 m and y = 12.9 m
42°
x = 9.6 m and y= 14.3 m
d. x = 7.2 m and y = 10.8 m
c.
Answer:
Option D. x = 7.2 m and y = 10.8 m.
Step-by-step explanation:
A. Determination of the value of x
Angle θ = 37°
Opposite = x
Hypothenus = 12 m
Using the sine ratio, the value of x can be obtained as follow:
Sine θ = Opposite /Hypothenus
Sine 37 = x/12
Cross multiply
x = 12 × Sine 37
x = 7.2 m
B. Determination of the value of y.
Angle θ = 42°
Opposite = x = 7.2 m
Hypothenus = y
Using the sine ratio, the value of y can be obtained as follow:
Sine θ = Opposite /Hypothenus
Sine 42 = 7.2/y
Cross multiply
y × Sine 42 = 7.2
Divide both side by Sine 42
y = 7.2 / Sine 42
y = 10.8 m
Therefore, x = 7.2 m and y = 10.8 m

The Vertices of a quadrilateral are A(4,-3),B(7,10),C(-8,2)and D(-1,-5).Find the length of each diagonal.Show me with the steps Please!
Answer:
13 and 17 units
Step-by-step explanation:
explaination is in pic.
The length of the diagonals of the quadrilateral AC and BD are 13 units and 17 units respectively, as per length between two points.
What is the length between two points in a plane?The length between two given points (x₁, y₁) and (x₂, y₂) will be:
√[(x₂ - x₁)² + (y₂ - y₁)²] units
Given, the vertices of a quadrilateral are A(4,-3),B(7,10),C(-8,2)and D(-1,-5).
Therefore, the diagonals of the quadrilateral will be AC and BD.
The coordinates of the diagonal AC are (4, - 3) and (- 8, 2).
Now, the length of the diagonal AC will be:
= √[(-8 - 4)² + (2 - (- 3))²] units
= √[(- 12)² + (5)²] units
= √[144 + 25] units
= √(169) units
= 13 units (length can't be negative)
Similarly, the coordinates of the diagonal BD are (7, 10) and (- 1, - 5).
Now, the length of the diagonal BD will be:
= √[(-1 - 7)² + (- 5 - 10)²] units
= √[(- 8)² + (- 15)²] units
= √[64 + 225] units
= √(289) units
= 17 units (length can't be negative)

Evaluate the following expression for x = 1 and y = -3.
3yºx+x-y
Answer:
8
Step-by-step explanation:
yº (in words, 'y to the power zero') is simply 1. We then have
3yºx+x-y = 3(1) + 2x - y = 3 + 2x - y.
Substituting 1 for x and -3 for y, we get the expression value:
3 + 2 - (-3) = 8

Answer:
peter: subtraction mistake at unit place . wrote 6 in place of 9
Jeff: subtraction mistake at tens place: wrote 4 while the correct digit is 3
peter: He has written 3 at unit place while correct digit is 2
John: he has carried 1 twice from 5 at hundred place and then subtracted 2 from it which gives value 1 at hundred place.
Step-by-step explanation:
we have to subtract 503 from 269
9
4 10 13
503
-269
____
234
Solution
since 3 is less than 9 , we take a carry from 0 but 0 cannot be carries so we take 1 carry from 5\
thus
5 becomes 4, 0 becomes 10,
now 10 can be give 1 carry to 3 at unit place, so 3 becomes 13
now 9 is subtracted from 13
13-4 = 9
this is the mistake of Peter
he has written 6 at unit place which should be
peter: subtraction mistake at unit place . wrote 6 in place of 9
____________________________________________________
since , 1 is carried from 10 at tens place, 9 is left at tens place
so we know subtract 6 from 9 at tens place
9-6 = 3
Here mistake is done by Jeff
Jeff: subtraction mistake at tens place: wrote 4 while the correct digit is 3
________________________________________________
at hundred place,
one is taken from 5 , hence 4 is left at hundred place
we have to subtract 2 from 4
4-2 = 2
hence,
Here, mistake done by both both Peter and jeff
peter: He has written 3 at unit place while correct digit is 2
John: he has carried 1 twice from 5 at hundred place and then subtracted 2 from it which gives value 1 at hundred place.
What is the solution to
Ax+ bx + C=0
Answer:
x = -C / (A + b)
Step-by-step explanation:
Without given values for the constants A, b, and C (Assuming they are constants), the best we can do is to isolate the variable x. Let's proceed to solve for x.
Ax + bx + C = 0
x (A + b) + C = 0
x (A + b) = -C
x = -C / (A + b)
So now, when you get the values of the constants A, b, and C, you can plug those in to solve for variable x.

Find the range of f(x) = –x + 4 for the domain {–3, –2, –1, 1}.
Answer:
{3, 5, 6, 7}
Step-by-step explanation:
Plug in each number form the domain and solve for f(x). The set of f(x) values is the range.
f(x) = -x + 4
f(-3) = -(-3) + 4 = 7
f(-2) = -(-2) + 4 = 6
f(-1) = -(-1) + 4 = 5
f(1) = -1 + 4 = 3
Range: {3, 5, 6, 7}

Find the third term of the geometric sequence when a^1=1/4 and r=−2
Answer:
The answer is 1Step-by-step explanation:
Since the sequence is a geometric sequence
For an nth term in a geometric sequence
[tex]A(n) = a ({r})^{n - 1} [/tex]
where n is the number of terms
a is the first term
r is the common ratio
From the question
a = 1/4
r = - 2
Since we are finding the third term
n = 3
So the third term of the sequence is
[tex]A(3) = \frac{1}{4} ({ - 2})^{3 - 1} [/tex]
[tex]A(3) = \frac{1}{4}( { - 2})^{2} [/tex]
[tex]A(3) = \frac{1}{4} \times 4[/tex]
We have the final answer as
A(3) = 1Hope this helps you
