solve 3/4 h - 12= 8 5/8
Answer:
27 1/2
Step-by-step explanation:
8 5/8 + 12 = 20 5/8
3/4h = 20 5/8
Divide 20 5/8 by 3/4 = 27 1/2. Therefore h = 27 1/2.
Answer:
h=55/2
Step-by-step explanation:
3/4h-12=69/8 simply 8 5/8
+12. +12. add 12 to each side
multiply each side by 4/3
h=55/2 or 27 1/2

what is the slope of (29,11) and (-3,-7)
Answer:
The slope is [tex]\frac{9}{16}[/tex]
Step-by-step explanation:
Hi there!
We are given the points (29, 11) and (-3, -7), and we want to find the slope of them.
The slope can be calculated from two points with the slope formula, which is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points.
We have two points given, but let's label their values to avoid any confusion when we actually calculate:
[tex]x_1=29\\y_1=11\\x_2=-3\\y_2=-7[/tex]
Now substitute into the formula (m is the slope).
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{-7-11}{-3-29}[/tex]
Subtract
m=[tex]\frac{-18}{-32}[/tex]
Reduce the fraction
m=[tex]\frac{9}{16}[/tex]
The slope is [tex]\frac{9}{16}[/tex]

Solve for the rate (as a %). Round to the nearest tenth of a percent when necessary,
$7.30 is what percent of $58.20?
In accordance with the query, we have 12.6% of $58.20. The closest tenth of one percent.
What percentage is 20%?It really is 100 * 20 / 100 = 20percent . In this circumstance, percentages are useful. When describing a change from one % to another, we use percentage points. The difference between 10% and 12% is four percent respectively (or 20 percent).
Solve for the rate (as a %). Round to the nearest tenth of a percent when necessary, we have following :
$7.30 is what percent of $58.20.
rate = (7.30 / 58.20) * 100
rate = 0.126034483 * 100 = 12.6%
Rounding to the nearest tenth of a percent, the rate is 12.6%.
So $7.30 is 12.6% of $58.20.

1.) P = 2T
2.) P = 3T + 50
3.) P = 2T – 50
4.) P = 3T – 50
Answer:
it's 4
Step-by-step explanation:
because
let's say
a. P = 100
T = 50
P = 3T - 50
= 3(50) - 50
= 150 - 50
= 100
and the same for the others
The equation of the profit will be P = 3T – 50. Then the correct option is 4.
What is the equation of line?The equation of line is given as
y = mx + c
Where m is the slope and c is the y-intercept.
The following chart shows the number of concert tickets sold and the profit earned.
Tickets Sold Profit (dollars)
50 100
100 250
150 400
200 550
The equation that defines the profit (P) with respect to the number of tickets sold (T) will be
m = 250 – 100 / 100 – 50
m = 150 / 50
m = 3
Then the equation will be
y = 3m + c
For T = 150, P will be 400.
400 = 150 x 3 + c
400 = 450 + c
c = –50
Then the equation of the profit will be
P = 3T – 50
Then the correct option is 4.

Answer:
The slope is -5/3.
The y-intercept is (0,10).
Step-by-step explanation:
1. The slope-intercept form of any linear equation is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.
2. Since -5/3 is in the place of m, the slope, that makes -5/3 the slope.
3. The y-intercept of a graph is the point where the graph intersects/crosses the y-axis. The x-coordinate of a point in any y-intercept will ALWAYS be 0.
4. Since 10 is in the place of b, the y-intercept, and given the information above, the y-intercept is (0,10).

What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
P(A) = 0.42, P(B) = 0.5
As, events A and B are independent.
so, P(A and B)
= P (A) . P(B)
= 0.42 x 0.5
= 0.21
Hence, the value of P(A and B) = 0.21

MULTIPLE CHOICE:
Jen and David owe $21,000 in loans for their two cars. The amount of the loan for Jen's car is $2,000 less than twice the amount of the loan for David's car. How much is each car loan? (Let j represent the amount of Jen's loan and let d represent the amount of David's loan.)
A. d + j = 21,000
2d − 2,000 = j
B. j + d = 21,000
2j − 2,000 = d
C. j + d = 21,000
2j + 23,000 = d
D. j + d = 2,000
2j − 21,000 = d
E. d + j = 2,000
2d − 21,000 = j
9514 1404 393
Answer:
A. d + j = 21,000; 2d − 2,000 = j
d = $7,666.67; j = $13,333.33
Step-by-step explanation:
The relationships given in the problem statement are ...
d + j = 21,000 . . . . . the total of the two loans is $21,000
2d -2000 = j . . . . . . Jen's is $2000 less than twice David's
__
These equations can be solved by substituting for j:
d +(2d -2000) = 21000
3d = 23000 . . . . . . . . . . . add 2000, collect terms
d = 23000/3 = 7666.67 . . . divide by the coefficient of d
j = 21000 -d = 21000 -7666.67 = 13333.33
Jen's loan is $13,333.33; David's loan is $7,666.67.

A home goods store sells 385 lamps in the month of July. If it sells 200 more
lamps in the next month, how many lamps does it sell in August?
Answer:
585
Step-by-step explanation:
We knew that the store sold 385 lamps in month of July. 200 more lamps were sold the next month which is August. Thus by addition, 585 lamps were sold in August.
What is addition?
Addition is one of the four basic operations of arithmetic, the other three being subtraction, multiplication and division. The addition of two whole numbers results in the total amount or sum of those values combined.
Lamps sold in July = 385
Given: 200 more lamps were sold in next month i.e., August.
Lamps sold in August = 385 + 200 = 585

Answer:
The probability of tossing heads and rolling either a 5 or 6 is possible (or unlikely). This because the probability of tossing heads is 1/2 and the probability of rolling a 5 or 6 is 1/6 so combined would be unlikely.

Divide 54 in to two parts so that four times the greater equals five times the less
Answer:
Let the both the parts be 'x' and 'y'
x>y
We know that 4x = 5y
so x = 5y/4
x + y = 54
Replacing x we get
(5y/4) + y = 54
(5y +4y)/4 = 54
9y = 216
y = 24
Replacing y in ' x+y = 54'
we get x = 30
Step-by-step explanation:
Hence the larger part is 30 whereas the smaller part is 24
