Answer:
28
Step-by-step explanation:
There were 7 chairs in each row, now they add three more to each row so now there's 10 chairs per row. There were 56 chairs altogether previously but now they need 5 times more so 56 times 5 equals 280. so with ten chairs per row and 280 chairs in total: 280/10 = 28. You'll need 28 rows

Find the value of x. Then find the measure of each labeled angle
Answers
Answer:
x = 111°
x° = 111°
(x-42)° = 69°
Step-by-step explanation:
Any polygon with *n* number of sides has an interior angle sum of (n-2) × 180°.
Therefore this right trapezoid must have an interior angle sum of 360° because
a trapezoid has 4 sides → n = 4 →
(n-2) × 180° = (4-2) × 180° = 2 × 180° = 360°
Because we are given a 90 degree angle with a set of parallel sides, the angle above that must also be a right angles well so these will total 180°.
The last two angles are given by the two expressions x°, and (x-42)°. Because we know the sum of these angles which are 360° we can create the following equation from these angles and solve!
180° + 2x - 42° = 360°
(Group the constants / numbers without a variable ; associative property of addition)
180° - 42° + 2x = 360°
(Find the total value of the constants)
138° + 2x = 360°
(subtract 138° from both sides to isolate 2x on the left side ; subtraction property of equality)
138° - 138° + 2x = 360° - 138°
(Work out the value of the constants again)
2x = 222°
(divide by 2 on both sides to cancel out the coefficient of 2 in 2x to get x by itself ; division property of equality)
2x / 2 = 222° / 2
(Simplify the two expressions)
x = 111°
_____________________
To find the measure of the x expressions, just substitute x = 111° into the expressions and simplify to find the measure!
So:
x = 111° → x° = 111°
x = 111° → (x-42)° → (111 - 42)° = (69)° →
(x-42)° = 69°

3. A student wrote a book which she plans to sell online for $13 per copy. Her total expenses were $85. Which function can be used to find the profit in dollars, d, when the student sells C, copies of the book?
Answers
Answer:
Her profit in dollars is;
d = 13c - 85
Step-by-step explanation:
Mathematically,
profit = sales - cost price
She sells at $13 per copy
so for c copies, total sales amount will be 13 * c= $13c
So the profit d in dollars will be;
d = 13c - 85

Step-by-step explanation:
Hope this helps!
The probability that the person will not die in the next year should be considered as the 0.00943.
Calculation of the probability:Since
the probability that a person will die in the next year is 507/100,000
So, it can be like
[tex]= (100,000 - 507) \div 100,000[/tex]
= 0.99493
hence, The probability that the person will not die in the next year should be considered as the 0.00943.

Jo's mother, Anne, is four times as old as Jo. In four years time, Anne will be three times as old as Jo. How old is Jo? (this is an easier version of a riddle we'll do in AP CS)
Answers
Answer:
Jo's age = x = 8 years
Step-by-step explanation:
Let
Jo's age = x
Jo's mother, Anne's age = 4x
In four years time, Anne will be three times as old as Jo.
Jo's age =3( x + 4)
Jo's mother, Anne's age = 4x + 4
How old is Jo?
Equate Jo's age and his mother's age
3(x + 4) = 4x + 4
3x + 12 = 4x + 4
3x - 4x = 4 - 12
-x = - 8
Divide both sides by -1
x = 8
Therefore,
Jo's age = x = 8 years

Mr. Randall, a salesperson, earns a weekly salary of $300 plus a commission of 7% of
his weekly sales of merchandise. Last week, Mr. Randall earned $426. This can be
represented by the equation below, where s represents his total sales, in dollars, for
the week.
$300 + $0.07s = $426
How many dollars worth of merchandise did Mr. Randall sell last week?
Answers
Answer:
-3
Step-by-step explanation:
Based on his weekly salary and commission, we can calculate that Mr. Randall sold goods worth $1,800.
In the formula given, sales is represented as s. To find the total sales, you can solve the equation:
300 + 0.07s = 426
0.07s = 426 - 300
s = 126 / 0.07
= $1,800
In conclusion, Mr. Randall sold $1,800 worth of goods.

y = x - 18 . . . . . add y-18
The coefficient of x is 1. That is the slope of the given line. The desired perpendicular line will have a slope that is the negative reciprocal of this:

19. Find 3 consecutive integers such that twice
the least integer is 12 more than the greatest
integer.
Answers
Answer:
et's start by defining the three consecutive integers.
.
If x represents the least of the three, then the next consecutive integer is x+1 and the
next consecutive integer is 1 more than that ... or x + 2
.
So the three consecutive integers are x, x+1, and x+2.
.
Twice the least integer is, as you correctly wrote, 2x.
.
12 more than the greatest integer is x+2 + 12 = x + 14
.
Since these two amounts must be equal, you can write:
.
2x = x + 14
.
Now you need to get rid of the x on the right side so that you end up with all the terms
containing x on one side of the equation and everything else on the other side. You can
get rid of the x on the right side by subtracting x from the right side. But if you subtract
something from the right side, you must also subtract it from the left side to keep the
equation in balance. So subtract x from both sides. When you do that, the x disappears
from the right side and the left side becomes 2x minus x which is just x.
.
So the equation is reduced to:
.
x = 14
.
If x is 14 then the next two consecutive integers are 15 and 16 ... x+1 and x+2. So the
three consecutive integers are 14, 15, and 16.
.
Check ... the least integer is 14. Twice the least integer is 28. Is 28 actually 12 more
than the greatest integer which is 16? Yes it is, so the problem checks.
.
You were on the right track, but you just needed to know the difference in the three integers
was that they were x, x+1, and x+2. Hope this helps to show you how you could work the
problem through to get the final answer.

What are some rules to solve an equation ?To solve an equation we follow BODMAS rule which stands for first solving which are inside brackets then we divide terms to each other if division is given.Then we multiply terms if multiplication is given.Next step we add terms if given.In last we do subtraction if it is in the given expression.If any of these operations are not given we just skip and do the next operation according to the BODMAS rule.
According to the given question
Charlotte wants to solve the equation 6(2x+1) – 3 = 4x – 5.
6( 2x + 1 ) - 3 = 4x - 5
12x + 6 - 3 = 4x - 5
12x + 3 = 4x - 5
12x - 4x = - 5 - 3

Answers
Step-by-step explanation:
3/4÷5/16
3/4×16/5
=12/5(2 2/5)
(3/4) divided by (5/16) in its simplest form is 12/5.
To divide two fractions, you can multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by flipping the numerator and the denominator. So, to divide (3/4) by (5/16), you can multiply (3/4) by the reciprocal of (5/16):
(3/4) ÷ (5/16) = (3/4) * (16/5)
Now, multiply the numerators and denominators:
Numerator: 3 * 16 = 48
Denominator: 4 * 5 = 20
3/4) ÷ (5/16) = 48/20
To simplify this fraction, find the greatest common divisor (GCD) of the numerator and the denominator, and then divide both by the GCD:
GCD of 48 and 20 is 4.
(48/4) ÷ (20/4) = 12/5.

Step-by-step explanation:
Given
[tex]1\ bow = 3\frac{1}{2}\ ft[/tex]

Determine the number of bows he can make
To do this, we simply divide the length of the ribbon by length of 1 bow:
i.e.
[tex]Number = Ribbon/1\ bow[/tex]
[tex]Number = 14\ ft/3\frac{1}{2}\ ft[/tex]
[tex]Number = 14/3\frac{1}{2}[/tex]
[tex]Number = 14/\frac{7}{2}[/tex]
Convert to *
[tex]Number = 14 * \frac{2}{7}[/tex]
[tex]Number = \frac{28}{7}[/tex]
[tex]Number = 4[/tex]
Hence, Mike can make 4 bows
