x +4= 6
A
В.
add 4
add the opposite of 4
C.multiply by the reciprocal of 4
D. multiply by the opposite reciprocal of 4
Answer:
B. add the opposite of four
Step-by-step explanation:
x + 4 = 6
x + 4 + (-4) = 6 + (-4)
x + 4 - 4 = 6 - 4
x + 0 = 2

A radial saw has a blade with a 6-in radius.
Suppose that blade spins at 1000 rpm.
Find the angular speed of the blade in
rad/min.
Answer:
The angular speed of the blade is of 166.67 rad/min
Step-by-step explanation:
The velocity, is given by the following equation:
[tex]v = rw[/tex]
In which r is the radius and w is the angular speed.
We use this relation to solve this question;
We have that:
[tex]v = 1000, r = 6[/tex]. We want to find w. So
[tex]v = rw[/tex]
[tex]1000 = 6w[/tex]
[tex]w = \frac{1000}{6}[/tex]
[tex]w = 166.67[/tex]
The angular speed of the blade is of 166.67 rad/min

Answer:
105
Step-by-step explanation:
180 - 140 = 40
180 - 145 = 35
35+ 40 = 75
180 - 75 = 105
a = 5
Answer:
105
Step-by-step explanation:
interior angle next to 145 is 180-145=35
interior angle next to 140 is 180-140=40
angle a= 180-35-40=105

Based on a 4-week work month and a 40-hour
workweek, which amount is closest to the combined
hourly wage needed for this family to pay its
budgeted expenses?
A
$1,107.50
B
$27.69
(с
$110.75
D
$55.38
Answer:
$27.69
Step-by-step explanation:
Given
Monthly budget (See attachment)
[tex]Month = 4\ weeks[/tex]
[tex]Week = 40 \ hour[/tex]
Required
Determine the closest hourly wage
From the attachment, the monthly budget is:
[tex]Budget = \$ 4430[/tex]
First, we calculate the closest weekly earnings.
Since a month = 4 weeks.
Then
[tex]Weekly\ Earnings = \frac{\$4430}{4}[/tex]
[tex]Weekly\ Earnings = \$1107.5[/tex]
Next, we calculate the hourly earnings:
Since 1 week = 40 hour
Then
[tex]Hourly\ Earnings = \frac{\$1107.5}{40}[/tex]
[tex]Hourly\ Earnings = \$27.6875[/tex]
From the list of options, the closest is: $27.69

Step-by-step explanation:
Hellen used a coupon she received in the mail at a local boutique that decreased her purchase of $85.20 by $12.78. Her sister used the same coupon and decreased her purchase of $63.80 by $9.57. Write the equation of a line, in the form y = mx + b, to model this linear relationship.
Answer:
y = 12665 (100⁻¹) + b
Step-by-step explanation:
To model this relationship, you're to write the equation of a line; in the form
y = mx + b
Now let y represent the full coupon value,
mx represent the amount spent by Hellen and her sister
and b, the change that's left on the coupon.
So, the summary of Hellen's transaction is:
$85.2 became $(85.2 - 12.78) which is = $72.42
The summary of her sister's transaction is:
$63.8 became $(63.8 - 9.57) which is = $54.23
So y - (72.42 + 54.23) = b
y - 126.65 = b
y = 126.65 + b
Separating m from x in mx, you have
y = 12665 x 1/100 + b
y = 12665 (100⁻¹) + b
Where m = 12,665 and x = 100⁻¹

Answer:
1. V(12) = $ 1200
2. V(20) = $ 4800
Step-by-step explanation:
The following data were obtained from the question:
V(t) = 150 × 2ᵗ/⁴
V(12) =?
V(20) =?
1. Determination of V(12)
Time (t) = 12 years
V(12) =?
V(t) = 150 × 2ᵗ/⁴
V(12) = 150 × 2¹²/⁴
V(12) = 150 × 2³
V(12) = 150 × 8
V(12) = $ 1200
2. Determination of V(20)
Time (t) = 20 years
V(20) =?
V(t) = 150 × 2ᵗ/⁴
V(20) = 150 × 2²⁰/⁴
V(20) = 150 × 2⁵
V(20) = 150 × 32
V(20) = $ 4800

When Jackson moved into a new house, he planted two trees in his backyard. At the time of planting, Tree A was 24 inches tall and Tree B was 36 inches tall. Each year thereafter, Tree A grew by 10 inches per year and Tree B grew by 7 inches per year. Let A represent the height of Tree A t years after being planted and let B represent the height of Tree B t years after being planted. Write an equation for each situation, in terms of t, and determine the height of both trees at the time when they have an equal height.
Answer:
For tree A: 24+10t
For tree B: 36+7t
They are at the same height at 4 years at a height of 64 inches
Step-by-step explanation:
To figure out when the trees are at the same height make the equations equal to each other and solve for T
24+10t=36+7t
Subtract 24 and 7t from both sides to get
3t=12
divide by 3 to get
t=4
This means at t=4 they are at equal height so we plug this into any of the equations
24+10*4
this is equal to 64
We can double check by plugging t=4 into the second equation
36+7*4
36+28=64

What are permutation and combination?In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.

∅,∅ ∅ω∅hope this helpsAll edges of a cube are expanding at a rate of 6 centimeters per second. (a) How fast is the volume changing when each edge is 5 centimeter(s)
Answer:
(a).The volume of cube is changing at the rate [tex]450 cm^3/s[/tex]
Step-by-step explanation:
Let x be the side of cube
[tex]\frac{dx}{dt}=6 cm/s[/tex]
We have to find the rate at which volume of cube changing when edge is 5 cm.
We know that
Volume of cube, V=[tex]x^3[/tex]
Differentiate w.r.t t
[tex]\frac{dV}{dt}=3x^2\frac{dx}{dt}[/tex]
Substitute the values
[tex]\frac{dV}{dt}=3(5)^2\times 6[/tex]
[tex]\frac{dV}{dt}=450 cm^3/s[/tex]
Hence, the volume of cube is changing at the rate [tex]450 cm^3/s[/tex]
