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

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.

let f={(1,2),(2,3),(5,6),(7,8) evaluate f(2)and f(5)?
Given:
[tex]f=\{(1,2),(2,3),(5,6),(7,8)\}[/tex]
To find:
The values of f(2) and f(5).
Solution:
If an ordered pair [tex](x,y)[/tex] is in the function [tex]f[/tex], then [tex]f(x)=y[/tex].
In the given set of ordered pairs one ordered pair is (2,3). So, by using the above definition, we get
[tex]f(2)=3[/tex]
In the given set of ordered pairs one ordered pair is (5,6). So, by using the above definition, we get
[tex]f(5)=6[/tex]
Therefore, the value of f(2) is 3 and the value of f(5) is 6.

The time t required to drive a certain distance varies inversely with the speed, r. If it takes 4 hours to drive the distance at 40 miles per hour, how long will it take to drive the same distance at 55 miles per hour?
A. about 2.91 hours
B. about 160.00 hours
C. about 22.00 hours
D. about 5.50 hours
Answer:
option D
Step-by-step explanation:
4 hours = 40 miles/per hour
? hour = 55 miles/per hour
step one, find rate :
40 divided by 40
1 hour = 10 miles/per Hour
If 4 x 10 = 40
then n x 10 = 55
It takes 5.5 OR 5.50 Hours/per hour for a Distance of 55 miles

7.5cm2
Step-by-step explanation:
5x3cm=15cm2 because of base x height/2 you would do
15cm2 divided by 2 since it is a triangle (a half of a square) which is 7.5cm2
Answer:
D.
Step-by-step explanation:
Area of a triangle is bh/2
So your base is 5 and your height is 3.
So you do 5*3 which is 15.
And lastly you do 15/2, which is 7.5. 7*2 is 14, and 8*2 is 16
So 7.5 times 2 is 15

-20=-8(a+4)-5(1-5a)
What is a
Answer:
a=1
Step-by-step explanation:
-20=-8(a+4)-5(1-5a)
Distribute
-20 = -8a -32 -5 +25a
Combine like terms
-20 =17a -37
Add 37 to each side
-20+37 = 17a-37+37
17 = 17a
Divide by 17
17/17 = 17a/17
1= a
If the scale factor from figure A to figure B is 3:8, find the value of X (giving brainliest and thanks to all!)
Answer:
x = 9
Step-by-step explanation:
Corresponding sides are in proportion, that is
[tex]\frac{x}{24}[/tex] = [tex]\frac{3}{8}[/tex] ( cross- multiply )
8x = 72 ( divide both sides by 8 )
x = 9

Angles = 50
Step-by-step explanation:
The angles are alternate interior angles and alternate interior angles are equal
4x+14 = 6x-4
Subtract 4x from each side
4x+14-4x = 6x-4-4x
14 = 2x-4
Add 4 to each side
14+4 = 2x-4+4
18 =2x
Divide by 2
18/2 =2x/2
9 =x
The angles are equal
4x+14 = 6x-4 = 4(9)+14 = 36+14 = 50

Sabiendo que la tangente son 4/3 dime el cos y sen estando el angulo en el tercer cuadrante de la circunferencia
Answer:
sen α = - 4/5
cos α = - 3/5
Step-by-step explanation:
tang α = 4/3
De la relación fundamental de la trigonometría sabemos:
sen² α + cos²α = 1
Dividiendo la ecuación anterior por cos² α
sen²α/cos²α + cos²α / cos²α = 1 / cos² α
tang²α + 1 = 1/ cos² α
(4/3)² + 1 = 1/ cos² α ⇒ 16/9 + 1 = 1/ cos² α
1/ cos² α = ( 16 + 9 ) / 9
1/ cos² α = 25/9
cos² α = 9/25
cos α = 3/5
y para calcular el sen α
sen² α = 1 - cos²α
sen² α = 1 - 9/25
sen² α = ( 25 - 9 )/ 25
sen² α = 16/25
sen α = 4 / 5
Ahora bien el angulo α está en el tercer cuadrante, en ese cuadrante tanto el seno como el coseno son negativos.
Respuesta:
sen α = - 4/5
cos α = - 3/5
