Answer:
80 students
Step-by-step explanation:
Given that,
Total number of students in 5th grade = 120
Two-thirds of the 5th graders are wearing sneakers today.
Let there are x graders wearing sneakers today.
[tex]x=120\times \dfrac{2}{3}\\\\=80[/tex]
Hence, 80 students are wearing sneakers today.

State true or false. If 9 is the solution of variable x in the equation fraction numerator 5 straight x space minus space 7 space over denominator 2 end fraction space equals space straight y, then the value of y is 28
Answer:
False
Step-by-step explanation:
Based on what is stated in the question :
Expressing the worded equation Mathematically,
(5x - 7) / 2 = y
If y = 28
(5x - 7) / 2 = 28
Cross multiply
5x - 7 = 28 * 2
5x - 7 = 56
5x = 56 + 7
5x = 63
x = 63 / 5
x = 12.6
Hence, x ≠ 9

Pamela's parakeet is currently in a rectangular bird cage that has a length of 3 feet, a width of 2 feet, and a height of 3 feet. Since the parakeet has gotten larger, Pamela is looking to buy a new rectangular bird cage. She wants the new cage to have a volume that is 4 times the volume of the parakeet's current cage. If Pamela wants to keep the length of the new cage the same, how must the other dimensions change?
Answer:
The volume of existing cage = length x widht x height = 3 x 2 x 3 = 18 cubic ft
Now she wants cage with volume four times of this cage
New Volume = V1 = 18 x 4 = 72 cubic ft
Keeping length same = 3 ft
Length x width x height = V1
3 x Width x height = 72
Width x height = 72 /3
Width x height = 24
Now multiple of 24 must be the width and height.
Taking width = 6 ft and height = 4 ft, we will get our answer
Proof:
Length x width x height = V1
3 x 6 x 4 = 72
Please help. Find the area of the composite figure
Okay so multiple 17 times 8 and 16 times 33 and then add the answers together and you should get 664!
Step-by-step explanation:
here's your solution
=> Firstly divide above picture in two parts
=> 1st = traingle
=> 2nd = trapezium
=> area of traingle = 1/2*base*height
=> height = 8
=> we need to find out base by using Pythagoras formula
=> base^2 = 17^2 - 8^2
=> base^2 = 289 - 64 = 225
=> base = √225
=> base of traingle = 15
=> now, area of traingle = 1/2*15*8
=>60sq.units
=> area of trapezium = 1/2(sum of p. sides ) *
distance between them
=> area = 1/2*(33 + 15)*16
=> area = 1/2*16*48
=> area = 384sq.units
=> area of whole figure = 384 + 60
= 444 sq.units

The ratio of green bags to white bags in the store is equal to 2 to 5.There are 30 white bags in the store how many green bags are there?
Answer:
12 green bags
Step-by-step explanation:
Given data
The given ratio of green bags to white bags is
=2 to 5
=2:5
Number of white bags=30
Applying the part to part method, let the number of green bags be x
so
2/5=x/30
cross multiply
30*2=5x
60=5x
divide both sides by 5
x= 60/5
x=12
Hence there are 12 green bags

Map quadrilateral ABCD to quadrilateral A′B′C′D′ with a rotation of 180° about the origin followed by a translation 3 units left and 7 units up.
Answer:
See Explanation
Step-by-step explanation:
Given
Shape: Quadrilateral ABCD
Transformations:
180 degrees rotation
3 units left
7 units up
Required
Determine A′B′C′D
The coordinates of ABCD is not given; So, I will solve generally.
Assume the coordinates of ABCD is (x,y)
When (x,y) is rotated 180 degrees, the new point is: (-x, -y)
Solving further:
Translation 3 units left
When a point (x,y) is translated b units left, the new point is (x - b, y).
So:
[tex](-x, -y) ====> (-x - 3, -y)[/tex]
Translation 7 units up
When a point (x,y) is translated h units up, the new point is (x, y + b).
So:
[tex](-x - 3, -y) ====> (-x - 3, -y + 7)[/tex]
Assume that the coordinates of A in ABCD before translation is (2,6).
i.e. A = (2,6)
The image A' will be:
[tex]A' = (-2-3,-6+7)[/tex]
[tex]A' = (-5,1)[/tex]
Question 1 A square has a perimeter given by the expression 20x + 24y Write an expression for the length of one side of the square.

Step-by-step explanation:
[tex]let \: the \: perimeter \: be \to p \\ let \: the \: side \: be \to s \\ since \to \: p = 4s \\ then \to \: 4s = 20x + 24y \\ hence \to \: 4s = 4(5x + 6y) \\ therefore \to \: s = 5x + 6y[/tex]
The equation y = 25x can be used to predict the height in feet, y, of the elevator after
1 seconds.
Find the height of the elevator when the time is 0 seconds.
Time (s), «
0 5 10 15
Height (ft), y
Answer:
y = 0 feet
Step-by-step explanation:
Given equation:
y = 25x
Where,
y = height (feet)
x = time (seconds)
25 = constant
Find the height of the elevator when the time is 0 seconds
y = 25x
y = 25(0)
y = 0 feet

A boat travelled 336 km downstream with the current. The trip downstream took 12 hours.
a) Come up with an equation to describe this relationship
b) If the current is moving at 2 km/h, how fast is the boat moving from its engine?
Answer:
When travelling downstream, the speed of the boat and the current add up.
Let the speed of the boat is b and the speed of the current is c.
Use distance formula:
d = st, d-distance, s- speed, t- timea)
Then we have equation:
12(b + c) = 336b)
If c = 2, then the equation is:
12(b + 2) = 336b + 2 = 28b = 26 km/hDistribute and evaluating

Choose the step that shows where a mistake is made (if there is one).
-2(x + 4) + 4x = 16
Step 1 -2x + 8 + 4x = 16
Step 2 2x + 8 = 16
Step 3 2x = 8
Step 4 x = 4
a Step 1
b Step 2
c Step 3
d Step 4
e No mistakes were made. The steps are correct and the answer is x = 4.
Answer:
The mistake is in step 1 when you do -2(x+4) you do the distributive property first -2 times x is -2x that's correct but -2 times 4 is not 8 it is -8
when you multiply by negatives the answer will always be a negative unless your multiply 2 negative number together then itll be positive ex. 4 × -4 = -16 (negative) but -4 × -4 = 16 (positive)
Solve for the missing arcs
Answer:
Step-by-step explanation:
arc KL = 60°
arc LNK = 360° - 60°
arc NJK = 180°
angle JQN = 60°
arc JN = 60°
arc JM = 60°+55° = 115°
arc MN = 55°
arc MKN = 360° - 55° = 305°
arc JML = 180°
angle MQL = 180° - 55° - 60° = 65°
arc ML = 65°
arc LN = 55° + 65° = 120°
