Answer:
The length of QS = 8
Step-by-step explanation:
From the above question:
Δ Q R S ≅ Δ T U V
Q S = 3 v + 2 , and T V = 7 v − 6 , enter the lengths of QS
Hence:
Step 1
We solve for v
QS = TV
3v + 2 = 7v - 6
Collect like ters
2 + 6 = 7v - 3v
8 = 4v
v = 8/4
v = 2
Step 2
Solving for Q S
Q S = 3 v + 2
v = 2
QS = 3(2) + 2
QS = 6 + 2
QS = 8
The length of QS = 8
One evening, a restaurant served a total of 5/6 of a loaf of wheat bread and 3/10 of a loaf of white bread. How many loaves were served in all?
Answer:
1 2/15 loaves
Step-by-step explanation:
In a restaurant:
Total Loaf of wheat bread = 5/6
Total Loaf is white bread = 3/10
The total number of loaves that were served in all =
Loaf of wheat bread + Loaf of white bread
= 5/6 + 3/10
Lowest Common Denominator = 30.
Hence:
= 25 + 9/30
= 34/30
= 1 4/30
= 1 2/15 loaves
The total number of loaves served in all = 1 2/15 loaves

A shade of green paint is made by mixing blue paint and yellow paint in the ratio of 4 to 3. How many pints of blue paint and yellow paint are needed to make 21 pints of the green paint? A. 12 pints of blue paint and 3 pints of yellow paint B. 9 pints of blue paint and 12 pints of yellow paint C. 16 pints of blue paint and 9 pints of yellow paint D. 12 pints of blue paint and 9 pints of yellow paint
Answer:
D
Step-by-step explanation:
The sum of the ratios = 4 + 3 = 7
The ratio of blue paint to the total paint = 4/7
The ratio of yellow paint to the total paint = 3/7
Pints of blue paint needed to make 21 pints of the green paint = 4/7 x 21 = 12 pints
Pints of yellow paint needed to make 21 pints of the green paint = 3/7 x 21 = 9 pints

what percent is 52.8 of 55? also how did u get itttt
Answer:
The answer is 96%.
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 55 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 55, so we can write it down as 100%=55.
4. We know, that x% equals 52.8 of the output value, so we can write it down as x%=52.8.
5. Now we have two simple equations:
1) 100%=55
2) x%=52.8
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=55/52.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 52.8 is what percent of 55
100%/x%=55/52.8
(100/x)*x=(55/52.8)*x - we multiply both sides of the equation by x
100=1.0416666666667*x - we divide both sides of the equation by (1.0416666666667) to get x
100/1.0416666666667=x
96=x
x=96
now we have:
52.8 is 96% of 55

What is the slope of the line?
Answer:
slope of the line is one
Step-by-step explanation:
goes up one, over one.
The slope is 1
To find slope, you first find two points on a graph. Pick one of the two and count to the other one and that gives you your slope! I hope I helped! :)

What equation in slope-intercept form represents the line that passes
through the points (3,-2) and (1, -3)?
Answer:
2y = x - 7
Step-by-step explanation:
The general equation of the line is;
y = mx + b
where m is the slope and b is the y-intercept
To get the slope, we use the slope formula
m = (y2-y1)/(x2-x1)
(x1, y1) = (3,-2)
(x2,y2) = (1,-3)
m = (-3+2)/(1-3) = -1/-2 = 1/2
So we have the equation as;
y = x/2 + b
Multiply through by 2
2y = x + 2b
To get the y-intercept value, we substitute any of the points
Let us use the first point
While 3 will go for x , -2 will go for y; thus we have;
2(-2) = 3 + 2b
-4 = 3 + 2b
2b = -4-3
2b = -7
b = -7/2
So the equation is;
2y = x -7

Write the equation to find the nth term in the arithmetic sequence. First term:-10 and common difference:2
Step by step
Answer:
2n - 12
Step-by-step explanation:
The nth term of an arithmetic progression is expressed as;
Tn = a+(n-1)d
a is the first term = -10
n is the number of terms
d is the common difference = 2
Substitute
Tn = -10 + (n-1)2
Tn = -10 + 2n-2
Tn = 2n -10-2
Tn = 2n - 12
Hence the nth term of the sequence is 2n - 12

is 1 1/2 equal to 1 to 2? why or why not
Answer:
No
Step-by-step explanation:
1 to 2 is 1/2
Answer:
No. See below.
Step-by-step explanation:
I've never heard anyone say this out loud. However, on Brainly, it is always interpreted as 1 1/2 = 1.5. So it is 1 plus 1/2.
1 to 2 is a ratio. For every set of car keys I have 2 house keys.
1 to 2 can be written either as 1/2 or 1:2 depending on how touchy your instructor is.
So no. 1 1/2 is not the same as 1:2

The Martin’s want to buy a new computer. The regular price is $849. The store is offering a 20% discount and a sales tax of 6% is added after the discount. What is the total cost of the computer?
Answer: The total cost of computer would be $719.95
Step-by-step explanation:
I use proportions for these types of problems so we begin with a proportion!
20/100=x/849
100x=16980
x=169.80
Then, after finding how much the discount is, we would subtract it.
849-169.80=679.20
Next, we would find the tax amount with another proportion to find what 6 percent of 679.20 is.
6/100=x/679.20
100x=4075.2
x=40.75
Lastly, we would add the tax, $40.75, plus the total after the discount, $679.20!
Hope this helps! Good luck! (:

what information can you automatically find just by looking at a function in standard form
Answer: The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equation.
