Answer:
I'm not sure you mean 2-(b/3) = -5/2 or (2-b)/3 = -5/2
Step-by-step explanation:
if
2-(b/3) = -5/2
12-2b = -15
12+15 = 2b
27 = 2b
27/2 = b
else
(2-b)/3 = -5/2
2(2-b) = -5×3
4-2b = -15
4+15 = 2b

Fatuma recently hired an electrician to do some necessary work. On the final bill, Fatuma was charged a total of $708. $480 was listed for parts and the rest for labor. If the hourly rate for labor was $57, how many hours of labor was needed to complete the job?
Answers
Answer:
4 hours.
Step-by-step explanation:
First we need to subtract $480 from $708.
$708-$480= $228.
Because the hourly rate is $57 we need to divide 228 by 57.
228÷57=4
The answer is 4 hours.

Given the equation Y-4=3/4(x+8) in point-slope form, identify the equation of the same line in standard form
Answers
Answer:
3x-4y=-40
Step-by-step explanation:
Hi there!
We're given the equation of the line, y-4=3/4(x+8) in point-slope form (y-\(y_{1}\)=m(x-\(x_{1}\)), where (\(x_{1}\),\(y_{1}\)) is a point and m is the slope)
We need to convert y-4=3/4(x+8) into standard form (ax+by=c, where a, b, and c are integer coefficients; a CANNOT be 0, and CANNOT be negative).
So we need to get y-4=3/4(x+8) out of point-slope form
We can do this by converting the equation into slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
to do this, we need to isolate y by itself in the equation
first, do the distributive property and distribute 3/4 on the right side
y-4=3/4x+6
add 4 to both sides
y=3/4x+10
now the equation is in slope-intercept form, but remember, we want it in standard form
x and y are on the same side in standard form, so let's subtract 3/4 x from both sides
-3/4x+y=10
however we aren't done; in standard form, the coefficients need to be integers (whole numbers), and a (the coefficient in front of x) CANNOT be negative
so let's multiply both sides by -4 to clear the fraction and change the sign of a
-4(-3/4x+y)=-4(10)
do the distributive property
3x-4y=-40
Hope this helps! :)

A recipe for sparkling grape juice calls for 1 ½ quarts of sparkling water and ¾ quart of grape juice. If you wanted to use 1 quart of grape juice, how many quarts of sparkling water would you need?
Answers
The required, we need 2 quarts of sparkling water to make the recipe with 1 quart of grape juice.
What is the Ratio?The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
We can use proportions to solve this problem. The ratio of grape juice to sparkling water in the original recipe is:
grape juice : sparkling water = 3 : 6
grape juice : sparkling water = 1 : 2
This means that for every quart of grape juice, we need 2 quarts of sparkling water.
If we want to use 1 quart of grape juice, we can use the same ratio to find the amount of sparkling water we need,
1 quart of grape juice : x quarts of sparkling water = 1 : 2
where x is the amount of sparkling water we need.
We can solve for x by cross-multiplying:
1 × 2 = x × 1
2 = x
Therefore, we need 2 quarts of sparkling water to make the recipe with 1 quart of grape juice.

A yo-yo is thrown toward the ground with an initial velocity of -4 feet per second. Its velocity v in feet per second t seconds after being thrown is given by v = 4t − 4, where t runs from 0 to 2 seconds. Find the times for which the yo-yo's velocity is greater than 2 feet per second or less than −2 feet per second. Express your answer as decimals.
Answers
Given the equation that represents this situation:
\(\begin{gathered} v(t)=4t-4 \\ t\in\lbrack0,2\rbrack \end{gathered}\)first, if we want to know when the yo-yo's velocity is greater than 2 feet per second, then:
\(\begin{gathered} v(t)>2 \\ \Rightarrow4t-4>2 \\ \Rightarrow4t>2+4=6 \\ \Rightarrow t>\frac{6}{4}=\frac{3}{2}=1.5 \\ t>1.5 \end{gathered}\)since t is defined between 0 and 2, the times for which the yoyo's velocity is greater than 2 feet per second is:
\(1.5then, if we suppose that the velocity is less than -2 feet per second, then:\(\begin{gathered} v(t)<-2 \\ \Rightarrow4t-4<-2 \\ \Rightarrow4t<-2+4=2 \\ \Rightarrow t<\frac{2}{4}=\frac{1}{2}=0.5 \\ t<0.5 \end{gathered}\)then, we have that the interval is:

A single card is drawn from a standard deck. Find the probability of the following event. (Enter your probability as a fraction.) Drawing a black card or a face card
Answers
Answer:
8/13
Step-by-step explanation:
In a standard deck there are 52 cards. Let A denote the event of drawing a black card and B denote the event of drawing face card. We have to find P(A or B) or P(A∪B).
P(A∪B)=P(A)+P(B)-P(A∩B)
There are 26 black cards in a standard deck so,
P(A)=26/52.
There are 12 face cards in a standard deck so,
P(B)=12/52.
There are 6 cards that are black face cards.
P(A∩B)=6/52.
P(A∪B)=P(A)+P(B)-P(A∩B)
P(A∪B)=26/52+12/52-6/52
P(A∪B)=38/52-6/52
P(A∪B)=32/52
P(A∪B)=8/13
Thus, probability of drawing a black card or a face card is 8/13.

Select the coordinates A′ and B′ after dilation of the line segment AB with a scale factor of 2, centered at the origin where the endpoints are A(3,7) and B(4,9)
Answers
Answer:
To perform a dilation with a scale factor of 2 centered at the origin, we need to multiply each coordinate of the original points A and B by the scale factor of 2.
The coordinates of point A after dilation are:
A′(2 * 3, 2 * 7) = A′(6, 14)
Similarly, the coordinates of point B after dilation are:
B′(2 * 4, 2 * 9) = B′(8, 18)
So, the endpoints of the dilated line segment are A′(6, 14) and B′(8, 18).
A = (3,7) becomes A′ = (2 * 3, 2 * 7) = (6,14)
B = (4,9) becomes B′ = (2 * 4, 2 * 9) = (8,18)
So, the new coordinates of A′ and B′ after dilation with a scale factor of 2 centered at the origin are (6,14) and (8,18), respectively

What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
We can use the Law of Sines,
Which states that for any triangle ABC:
a/sin(A) = b/sin(B) = c/sin(C)
where a, b, and c are the lengths of the sides of the triangle opposite the angles A, B, and C.
Now,
a = UV = u = 3.4 inches
A = ∠TUV
= 180° - m∠U - m∠V
= 180° - 144° - 35°
= 1°
B = ∠UTV
= m∠U
= 144°
C = ∠TVU
= m∠V
= 35°
Using the Law of Sines,
v/sin(C) = u/sin(B)
Substituting in the values.
v/sin(35°) = 3.4/sin(144°)
Solving for v.
v = (3.4 × sin(35°)) / sin(144°)
v = 1.97 inches
Therefore,
The length of v to the nearest 10th of an inch is 2.0 inches.

What is division?
One of the four fundamental operations of arithmetic, or how to mix numbers to create new ones, is division. Addition, subtraction, and multiplication are the other operations.
The opposite of multiplication is division. When you multiply three groups of four to produce twelve, you get four in each group when you split twelve into three equal groups.
Let, the number 392,000 is divided by 10.
That means, \(\frac{392000}{10}\)

The first step is correct because the divisor is reversed and the operation changed to multiplication.
The second step is also correct because 4x + 4 was correctly factored into 4(x + 1).
Then, the third step is also correct wherein (x + 1) was canceled out because it is a common factor on both numerator and denominator. Then, 6/12 was simplified to 1/2, and y/y² was simplified to 1/y.
Lastly, 1/2 times 1/y is 1/2y.

Two rectangles of the same shape have areas of 676 and 3,457 square centimetres. If the shorter side of the larger rectangle is 41 centimetres, what are the dimensions of the smaller one?
Answers
The dimensions of the smaller rectangle are 13 centimeters by 52 centimeters.
Let's assume the dimensions of the smaller rectangle are length L and width W (in centimeters).
We know that the area of the smaller rectangle is 676 square centimeters:
L * W = 676 ----(1)
We also know that the larger rectangle has a shorter side of 41 centimeters. Let's say the corresponding longer side of the larger rectangle is H centimeters.
The area of the larger rectangle is 3457 square centimeters:
41 * H = 3457 ----(2)
Our current set of equations contains two unknowns. In order to get the smaller rectangle's dimensions, we can simultaneously solve these equations.
In order to find H, we can use equation (2):
H = 3457 / 41
H ≈ 84.22
Now we can substitute this value of H into equation (1):
L * W = 676
We need to find the dimensions (L and W) that multiply to give 676. We can start by looking for factors of 676.
Factors of 676: 1, 2, 4, 13, 26, 52, 169, 338, 676
By trial and error, we can see that the factors that give a close match to the dimensions of the larger rectangle (41 and 84.22) are 13 and 52:
L = 13
W = 52
Therefore, the smaller rectangle has measurements of 13 by 52 centimetres.
