expanded form of 5(2m)³
Answer:
[tex]40m^{3}[/tex]
Step-by-step explanation:
Because of order of operations, you do exponent first. [tex](2m)^{3} =8m^{3}[/tex]. Lastly 8 multiplied by 5 is 40, so the answer is [tex]40m^{3}[/tex]

Mr. Mayhood had 4½ pounds of sand in a bucket. He put 2¾ pounds
of sand around his flower bed. How much sand did he have left in the
bucket?
Answer:
1 3/4 pounds.
Step-by-step explanation:
4 1/2 = 4 2/4
4 2/4 - 2 3/4 = 1 3/4
Answer:
1 [tex]\frac{3}{4}[/tex] pounds of sand is left in the bucket
Step-by-step explanation:
4.5 - 2.75 = 1.75 or 1 3/4
Christopher saves $550 every month. Assume that Matthew and Christopher both save money at constant rates. Whose unit rate s higher, and
by how much?
OA Christopher's savings per month Is higher than Matthew's savings per month by $50 per month.
OB. Matthew's savings per month is higher than Christopher's savings per month by $50 per month.
OC. christopher's savings per month Is higher than Matthew's savings per month by $100 per month.
OD. Matthew's savings per month is higher than Christopher's savings per month by $100 per month.
OE. Matthew and Christopher both save the same amount, $550 per month.
Answer:
The correct answer is:
Matthew's rate is higher by $50 per month.
Step-by-step explanation:
We know that Christopher's rate is $550 per month.
To find Matthew's rate, we will treat the data we have as ordered pairs:
(3, 1800)
(6, 3600)
(9, 5400)
We find the slope of the line between these points. The formula for slope is:
Using the first two points, we have:
To verify Matthew saves the same amount each month, we will find the slope between the second two points and make sure they're the same:
Matthew's rate is $600 per month.
This is higher than Christopher's by 600-550=$50 per month.

Answer:
9-pack of hot dogs for $3.61
Answer:
Step-by-step explanation:
This is a question on the unit price. The better buy is the lower unit price. But that only works if you have 8 people to share the dogs with.
2 dogs cost 0.81
1 dog is 0.81/2 = 0.405 which you should write as 0.41
9 dogs are 3.61
1 dog is 3.61/9 = 0.401 what you (again) should be 0.41
Ever so marginally, you should pick the 2 dogs if there are only 2 people and 9 dogs if you are buying for a baseball team.

Answer:
Blue balloons = 12
Step-by-step explanation:
Total no of balloons = 21
Let us assume that the ratio of blue balloons to green balloons is 4:3.
Let there are 4x blue balloons and 3x green balloons.
ATQ,
4x+3x = 21
7x = 21
x = 3
Blue balloons = 4x
= 4(3)
= 12
Hence, she will have 12 blue balloons at her party.
The dimensions of a standard tennis court are 36 ft. 78 ft. with a net that is 3 ft. high in the center. The
court is modified for players aged 10 and under such that the dimensions are 27 ft. x 60 ft., and the same
net is used. Use similarity to determine if the modified court is similar to the standard court.
Try to dilate the modified court to make it the same size as the standard court. The dilation factor for the
width is
. The dilation factor for the length is
. Based on similarity, the modified
court is similar to the standard court.
Answer:
The dilation factor of the width is 3/4
The dilation factor of the length is 10/13
The standard court and the modified court are not similar
Step-by-step explanation:
The given dimension of a tennis courts are given as follows;
The width of the standard tennis court = 36 ft.
The length of the standard tennis court = 78 ft.
The height of the net of the standard tennis court = 3 ft.
The width of the modified tennis court = 27 ft.
The length of the modified tennis court = 60 ft.
The height of the net of the standard tennis court = 3 ft.
The dilation factor of the width = (Modified court width)/(Standard court width)
∴ The dilation factor of the width = (27 ft.)/(36 ft.) = 3/4
Therefore, the width of the modified court = 3/4 × The width of the standard court
∴ The dilation factor of the length = (60 ft.)/(78 ft.) = 10/13
Therefore, the length of the modified court = 10/13 × The length of the standard court
The dilation factor for the width is different from the dilation factor for the length and the net of both courts are of equal dimension, therefore, based on similarity theorem, both courts are not similar.
Cardinal number of set A=1,2,3,4,0,7 is 6
Answer:
n(A) = 6
Step-by-step explanation:
Let consider a set A = {a, m, b, d, h}. There are five elements in the set. The no of elements in a set is known its cardinality. Since set A has five elements, its cardinality number is 5. The cardinality of the set A is denoted by n(A).
Hence, from the given information:
The set A = {1, 2, 3, 4, 0, 7} have a cardinality number of 6
n(A) = 6

Answer:
12a) 4L - 6 = Perimeter
13) 4(6x + 9)
Step-by-step explanation:
for #12: two sides of the rectangle are referred to as L
The other two sides can be referred to as L-3 (these sides are the width, which are 3 less than the length)
Perimeter = sum of all sides; so, 2L + 2(L-3)
P = 2L + 2L - 6
= 4L - 6
Answer: 12. The expression is 2L+2(L-3)
13. The answer is 6x+9
Step-by-step explanation:
12. The perimeter of a rectangle is 2*length +2*width. So, in this case (when L is the length of the rectangle) the perimeter should be 2L+2(L-3). If you simplify you will get 4L-6.
13. The perimeter is just the value you get when all the sides of a shape are added. A square has 4 equal sides. So, just divide the perimeter, which in this case is (24x+36), by 4. You should get 6x+9.

On 1 September, Leila starts to go swimming every day.
She swims 30 lengths of the swimming pool every day. The swimming pool is 20m long.
Work out the date when Leila has swum a total of 10 km.
Answer:
22 November
Step-by-step explanation:
First we have to find the total length she swims in 1 day
= 2(length of the swimming pool) x no. of lengths she swims in 1 day
=2x30x20
=120m she covers in 1 day
10km = 10,000m
no of days= total distance/ distance she covers in 1 day
=10000/120
=83.3 days

Find the relation and solve the answers. Options are given below.
Answer:
The correct option is;
A. 453
Step-by-step explanation:
The given numbers are not related by factors, because the factors of 779 are 1, 19, 41, and 779
Similarly the factors of 926 are 1, 2, 463, 926
Therefore, the numbers are related by direct association of each digit of the central number to each of the three numbers on the vertices of the triangle as follows;
For the first triangle, we have the numbers at the vertices are; at the top, 14, at the bottom left is 21, and at the bottom right is 36, we have;
Top number divided by 2 gives 14/2 [tex]{}[/tex] = 7
Bottom left number divided by 3 gives 21/3 [tex]{}[/tex] = 7
Bottom right number divided by 4 gives 36/4 = 9
From which we have the number at the center which is 779
Similarly, for the second triangle, we have the numbers at the vertices are; at the top, 18, at the bottom left is 6, and at the bottom right is 24, we have;
Top number divided by 2 gives 18/2 [tex]{}[/tex] = 9
Bottom left number divided by 3 gives 6/3 [tex]{}[/tex] = 2
Bottom right number divided by 4 gives 24/4 = 6
From which we have the number at the center which is 962
Therefore, when we have, the numbers at the vertices as follows;
At the top, 8, at the bottom left is 15, and at the bottom right is 12, we have;
Top number divided by 2 gives 8/2 [tex]{}[/tex] = 4
Bottom left number divided by 3 gives 15/3 [tex]{}[/tex] = 5
Bottom right number divided by 4 gives 12/4 = 3
From which we have the number at the center is 453.

Answer:
X = 41°
Step-by-step explanation:
Sum of interior Angles of a ∆ is 180°[tex] \angle1 + \angle2 + \angle3 = 180 \degree [/tex]
[tex]Here \\ \angle1 = 105 \degree \\ \angle2 = ? \\ \angle3 = x[/tex]
[tex] \angle4 = 146 \degree[/tex]
[tex]here \: \angle2 + \angle4 = 180 \degree \\ \: (liner \: pair \: angle) degree\\ \angle2 + 146\degree = 180 \degree \\ \angle2 = 180 \degree - 146\degree \\ \angle2 = 34\degree[/tex]
[tex] \angle1 + \angle2 + \angle3 = 180 \degree \\ 105\degree + 34\degree + x = 180\degree \\ 139\degree + x = 180\degree \\ x = 180\degree - 149\degree \\ x = 41\degree[/tex]
