At the book fair 32 books were sold in the first 2.5 hours. At this rate, how many books will be sold in the 10 hours of the book fair?
Answer:
128
Step-by-step explanation:
set up a proportion of # books sold/hours = # books sold/hours
let 'b' = # books sold
32/2.5 = b/10
cross-multply to get:
2.5b = 320
b = 320/2.5
b = 128
I will mark brainlyest please help me! Russ compared the heights of the players on two basketball teams, Team 1 and Team 2. He recorded the data as shown below.
Answer:
Step-by-step explanation:
Median is the dot near the middle of each box. Since median of team one is to the left of that of team 2,
Team 1 has a lesser median than Team 2.
InterQuartile Range (IQR) is the length of the box, so
Team 1 has a bigger IQR than Team 2.
See diagram.
Determine whether each sequence is arithmetic or geometric. Sequence 1: –10, 20, –40, 80, ... Sequence 2: 15, –5, –25, –45, ...
A. Sequence 1 is arithmetic and Sequence 2 is geometric.
B. Both sequences are geometric.
C. Sequence 2 is arithmetic and Sequence 1 is geometric.
D. Both sequences are arithmetic.
sequence 2 may be arithmetic because -20 but I can't find out what sequence 1 is
Answer:
C. Sequence 2 is arithmetic and Sequence 1 is geometric.
Step-by-step explanation:
Arithmetic sequence is where number is continuously increased or decreased in same amount we can see that the second sequence is decreases by 20 continuously
Geometric sequence is where a number is continuously divided or multiplied by same number
we can see that the first sequence is continuously multiplied by (-2)

Answer:
The correct answer is – 1/2
Answer:
The answer is -1/2
Step-by-step explanation:
If we compare this with y = mx + c, we can do a comparison. m is the slope and c is the added constant.
Since y = -1/2 x + 1/4,
m = -1/2
Since m is the slope, the slope is -1/2.

Elijah has \frac{1}{2} 2 1 bag of candy. A bag of candy weighs 55 pounds. How many pounds of candy does Elijah have?
Answer: 137.5 pounds
Step-by-step explanation:
Elijah has 2¹/₂ bags of candy. A single bag of candy weighs 55 pounds so to find the quantity of pounds that Elijah has, multiply 55 by the number of bags that Elijah has:
First convert bags to mixed fraction:
= 2¹/₂ = 5/2
Quantity that Elijah has:
= Number of bags * Weight per bag
= 5/2 * 55
= 137.5 pounds
Tylers mom had a coupon for four dollars each of the train tickets.If they bought If they bought five train tickets and paid a total of $145, what was the original cost of each ticket?
Answer:
The original cost of each ticket will be = $33
Step-by-step explanation:
Number of coupons Tylers mom had = 5
The value of each coupon is = $4
Total value of coupons = 5 x 4 = $20
In order to find the original cost of the ticket, we just have to add the value of coupons to the amount paid for tickets.
The original cost of tickets = $145 + $20
The original cost of tickets = $165
Thus, the original cost of each ticket will be = 165 / 5
Thus, the original cost of each ticket will be = $33

The sides of a triangle are x cm, (x -1) cm and (x+2) cm. IF the perimeter is 31 cm, then the SHORTEST side is
Answer:
9 cm
Step-by-step explanation:
Applying,
P = a+b+c................. Equation 1
Where P = Perimeter of the triangle, a, b,c are the three sides of the triangle respectively.
From the question,
Given: P = 31 cm, a = x cm, b = (x-1) cm, c = (x+2) cm
Substitute these values into equation 1, and solve for x
31 = x+(x-1)+(x+2)
31 = 3x+1
3x+1 = 31
3x = 31-1
3x = 30
divide both side by 3 to get x
3x/3 = 30/3
x = 10.
Therefore, the sides of the triangle are
a = x = 10 cm,
b = (x-1) = (10-1) = 9 cm
c = (x+2) = (10+2) cm = 12 cm
Hence the shortest side is 9 cm

What pair of angles must have the same measure?I'll give brainliest if its correct.
Answer:
[tex]\text{(C) }\angle 2\text{ and }\angle 7[/tex]
Step-by-step explanation:
Angle 2 corresponds with angle 6 and since all corresponding angles are equal, [tex]\angle 2=\angle 6[/tex]. Angle 6 and angle 7 happen to be vertical angles (opposite side of an intersection of two lines). Since all vertical angles are also equal, [tex]\angle 6=\angle 7[/tex] and by substitution, we have: [tex]\implies \boxed{\text{(C) }\angle 2\text{ and }\angle 7}[/tex]
The following is a student’s work when solving for y. There is a mistake in the work. What is the mistake? What is the correct answer? Explain. Step 1: P=2x+2y Step 2: P+2x=2y Step 3: P+2x2=y
Answer:
Part 1
The mistake is Step 2: P + 2·x = 2·y
Part 2
The correct answer is
Step 2 correction: P - 2·x = 2·y
(P - 2·x)/2 = y
Step-by-step explanation:
Part 1
The student's steps are;
Step 1; P = 2·x + 2·y
Step 2: P + 2·x = 2·y
Step 3: P + 2·x/2 = y
The mistake in the work is in Step 2
The mistake is moving 2·x to the left hand side of the equation by adding 2·x to P to get; P + 2·x = 2·y
Part 2
To correct method to move 2·x to the left hand side of the equation, leaving only 2·y on the right hand side is to subtract 2·x from both sides of the equation as follows;
Step 2 correction: P - 2·x = 2·x + 2·y - 2·x = 2·x - 2·x + 2·y = 2·y
∴ P - 2·x = 2·y
(P - 2·x)/2 = y
y = (P - 2·x)/2

x(x+2) + y (x + 2) - 5(x + 2)
factor
Answer:
x² + xy - 3x + 2y - 10
Step-by-step explanation:
x(x + 2) + y(x + 2) - 5(x + 2)
x² + 2x + y(x + 2) - 5(x + 2)
x² + 2x + xy + 2y - 5(x + 2)
x² + 2x + xy + 2y - 5x - 10
x² - 3x + xy + 2y - 10
x² + xy - 3x + 2y - 10
Johanna buys two poster frames that have the same area, but different shapes. One is a rectangular frame with a width of 40 inches and a length of 30 inches. The other frame is square. What a poster with dimensions of 36 inches X 36 inches fit in the square frame?
Answer:
No, the poster would not fit in the frame
Step-by-step explanation:
A rectangle is a quadrilateral (has 4 sides and 4 angles) with two pair of opposite and equal sides.
A square is a quadrilateral in which all sides are equal.
Given that the rectangular frame has a width of 40 inches and a length of 30 inches. The area of the rectangular frame is:
Area of rectangular frame = length * breadth = 40 inches * 30 inches = 1200 in²
Since the square frame has the same area as the rectangular frame, hence:
Area of square frame = length * length
length² = 1200
length = √1200 = 34.64
Therefore the dimensions of the square frame is 34.64 inches by 34.64 inches.
Hence a poster with dimensions of 36 inches X 36 inches cannot fit in the square frame.

M(x)=−(x−5) 2 +25m, left parenthesis, x, right parenthesis, equals, minus, left parenthesis, x, minus, 5, right parenthesis, squared, plus, 25 What is the maximum possible number of mosquitoes?
Answer:
25
Step-by-step explanation:
Given the function that represents the amount of mosquitoes as;
M(x) = -(x-5)² + 25
To get the maximum mosquitoes possible, we need to first find x;
At the maximum dM/dx = 0
dM//dx = -2(x-5)
0 = -2(x-5)
-2(x-5) = 0
-2x + 10 = 0
-2x = -10
x = 10/2
x = 5
Substitute x = 5 into the function;
M(5) = −(5−5)² +25
M(5) = 0+25
M(5) = 25
Hence the maximum number of mosquitoes is 25
Answer:
25 Million Mosquitoes

what is an equation of the line that passes through the points (3, 4) and (-4, -3)?
Answer:
y = x + 1
Step-by-step explanation:
Equation of line : y = mx + b, m = slope, b = y intercept
Find slope, m
[tex]Slope, m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]= \frac{-3 - 4}{-4 - 3} \\\\=\frac{-7}{-7}\\\\=\frac{7}{7}\\\\= 1[/tex]
Equation of line : [tex](x_1, y_1) = ( 3, 4 )[/tex]
[ You can choose any set of points from the given points. ]
[tex](y - y_1) = m(x - x_1)[/tex]
[tex](y - 4 ) = 1 \times ( x - 3)\\\\y - 4 = x - 3\\\\y = x - 3 + 4 \\\\y = x + 1[/tex]
