Answer:
120
Step-by-step explanation:
The LCM of 24 and 30 is 120. To find the least common multiple (LCM) of 24 and 30, we need to find the multiples of 24 and 30 (multiples of 24 = 24, 48, 72, 96 . . . 120; multiples of 30 = 30, 60, 90, 120) and choose the smallest multiple that is exactly divisible by 24 and 30, i.e., 120.

What are the coordinates of point Q?
How many units below the x-axis is point Q?
Will point Q' be above or below the x-axis?
How many units above or below the x-ax will it be?
Does reflection across the x-axis change the x-coordinates? If yes, how?
Does reflection across the x-axis change the y-coordinates? If yes, how?
What are the coordinates of point Q?
What are the coordinates for the other vertices of Q'R'ST?
R’
S’
T’
Draw figure Q’R’S’T’ on the coordinate plane and label the pints at the vertices
Answer:
Q (-4, -2); 2 units; Q' will be above the x-axis; 2 unites; no; yes, the y coordinates are multiplied by -1; Q' (-4, 2); R' (-2, 2), S' (1, 5), T' (-2, 5);
Step-by-step explanation:
even after a reflection over the x-axis, each points distance from the x-axis will stay the same
the x-coordinates don't change because the distance from the y-axis stays the same
the picture below shows points of Q'R'S'T', just connect the vertices

Answer:
Area = 23.12 cm²
perimeter = 24.28 cm
Step-by-step explanation:
top shaded region is circular arc with 90° sector angle
so perimeter of arc is 90 / 360 * 2πr
here radius of arc is half the length of square side
r = 6.8/2 = 3.4
top area shaded perimeter = 90/360 * 2 * 3.14 * 3.4
= 1/4 * 2 * 3.14 * 3.4
= 5.338
bottom region perimeter is also same
total perimeter of shaded region is = side + side + two arcs
= 6.8 + 6.8 + 2 * 5.338
= 13.6 + 10.676
= 24.276
= 24.28
Area of top shaded region is 90/360 * πr²
A = 1/4 * 3.14 * 3.4²
= 9.0746
bottom shaded region area is half of area of square - area of bottom arc
= 6.8 * 3.4 - 9.0746
= 23.12 - 9.0746
= 14.0454
so total area of shaded region is 9.0746 + 14.0454
= 23.12
or you can just calculate area as half of area of total square = 6.8² / 2
= 23.12

Answer:
£6.25
Step-by-step explanation:
2.25 x 15 = 33.75
40 - 33.75 = 6.25
Answer:
£6.25
Step-by-step explanation:
Hii,
So if each lesson is 2.25, you times this by 15 to get the total amount of payment. £2.25 x 15 = 33.75
To get change, you need to take away the amount you are giving by how much the bill is.
£40 - £33.75 = £6.25

Check the picture below.
now, notice the triangles made, 3 right triangles with legs of 5 and 4 each.
looking at quadrilateral (1), from the leg 5 units long, we have a line with a run of -1 and a rise of 3, from the leg 4 units long, we have a line with a run of 4 and a rise of -1.
Now, quadrilaterals (2) and (4) display the same lengths and rise and runs, which means they're all congruent, quadrilateral (3) has no equal.
so 1 ≅ 2 and 1 ≅ 4.

Mrs. Smith is shopping for a toy chest to go in her kids' playroom. She looks at the options shown.
Image_7181
If Mrs. Smith needs a toy chest that has at least 35 ft3 of storage space, which chest should she purchase
The volume of a cuboid toy chest is equal to their product of the length,
width, and height.
The correct option for the toy chest she should purchase is; Only toy chest A will provide the necessary storage space.Reasons:
The dimensions of the toy chest are;
Toy chest A;
Length = 5 feet
Width = 4 feet
Height = 2 feet
Toy chest B;
Length = 4 feet
Width = 2 feet
Height = 4 feet
Volume of Toy chest A = 5 ft. × 4 ft. × 2 ft. = 40 ft.³
Volume of Toy chest B = 4 ft. × 2 ft. × 4 ft. = 32 ft.³
The volume of the toy chest Mrs. Smith needs = 35 ft.³
The toy chest Mrs. Smith should purchase is Toy chest A, that has a volume of 40 ft.³, which can store items that with a volume of 35 ft.³
The correct option is; Only toy chest A will provide the necessary storage space
Possible question options obtained from a similar question found online are;
Either toy chest have the storage space needed
Neither has the storage space needed
Only toy chest A
Only toy chest B

Steven and his family ordered a meal that cost $136.50. Steven paid 14% sales tax and left a 20% tip on $136.50. What was the total cost?
Answer:
182.91
Step-by-step explanation:
First multiply the cost of the meal by the sales tax percentage as a decimal (.14)
[tex]136.50*.14=19.11[/tex]
Then multiply the cost of the meal before sales tax by the tip percentage
[tex]136.50*.2=27.30[/tex]
Then add the tip and the sales tax on top of the cost of the meal to calculate the total cost
[tex]136.5+19.11+27.3=182.91[/tex]

Jeremy can row 2/3 of a mile in 1/2 hour how long will it take him to row 1 mile?
Answer:
It takes 3/4 of an hour to go 1 mile
Step-by-step explanation:
You can do this by setting up a proportion and by using decimals for some fractions
2/3 = 0.66667 Miles
1/2 = 0.5 hours
0.66667/0.5 = 1/x Cross multiply
0.66667 * x = 0.5 * 1 Simplify
0.66667 * x = 0.5 Divide both sides by 0.66667
x = 0.5 / 0.66667
x = 0.74999625 Notice when rounded this is 0.75
x = 0.75 Now notice that 0.75 as a fraction is 3/4
x = 3/4
Jeremy can row 2/3 of a mile in 1/2 hour then it will take him 3/4 hour to row 1 mile.
If Jeremy can row 2/3 of a mile in 1/2 hour, then the time it takes him to row 1 mile can be found by setting up a proportion:
(2/3 mile) / (1/2 hour) = 1 mile / (x hours)
Cross-multiply:
(2/3) × x = 1 × (1/2)
Now solve for x:
x = (1/2) / (2/3)
x = 3/4
So, it will take Jeremy 3/4 of an hour (or 45 minutes) to row 1 mile.
