What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

A cruise boat travels 48 miles Downstream in 2 hours and returns Upstream in 3 hours. Find the speed of the boat in still water and the rate of the Stream.

Answers

Let x be the speed of the boat in still water and y be the speed of the current of the river.
The downstream speed will be x+y, the upstream speed will be x-y.
but:
distance=speed*time
therefore; as the boat travels in 2 hours downstream we shall have:
2(x+y)=48......i
and as the boat travels upstream we shall have:
3(x-y)=48........ii
simplifying i and ii we get:
x+y=24....iii
x-y=16....iv
adding the above iii and iv we get
2x=40
x=40/2=20
substituting x=20 into iii we obtain:
20+y=24
y=24-20
y=4
so the speed of the boat in still waters is 20 miles per hour
the rate of the stream is 4 miles per hour

Final answer:

The speed of the cruise boat in still water is 20 mph and the rate of the stream is 4 mph.

Explanation:

The student is asking about a problem related to the rate of the boat in still water and the rate of the stream, given the times it takes to travel downstream and upstream. To solve this, we can use the following steps:

Let the speed of the boat in still water be b mph and the rate of the stream be s mph.Downstream, the effective speed is b + s and upstream it's b - s.Using the formula distance = speed imes time, we have two equations based on the given information: 48 miles = (b + s) imes 2 hours for downstream and 48 miles = (b - s) imes 3 hours for upstream.Solve the two equations simultaneously to find the values of b and s.

Let's solve the equations:

48 = 2(b + s) => 24 = b + s48 = 3(b - s) => 16 = b - s

Adding both equations:

24 + 16 = (b + s) + (b - s) => 40 = 2b => b = 20 mph (boat speed in still water)Subtracting the upstream equation from the downstream equation:24 - 16 = (b + s) - (b - s) => 8 = 2s => s = 4 mph (rate of the stream)

Therefore, the speed of the boat in still water is 20 mph and the rate of the stream is 4 mph.

Angles C and D are complementary. The measure of angle D is 25 degrees greater than the measure of angle C. What is the measure of each angle?

Answers

32.5 + 57.5. It adds up to 90 degrees.

Final answer:

Angle C measures 32.5 degrees and angle D measures 57.5 degrees.

Explanation:

Let's represent the measure of angle C as x. Angle D is 25 degrees greater than angle C, so we can represent the measure of angle D as x + 25.

We know that angles C and D are complementary, so their measures must add up to 90 degrees.

Therefore, we can set up the equation:

x + (x + 25) = 90

Combining like terms, we get:

2x + 25 = 90

Subtracting 25 from both sides, we get:

2x = 65

Dividing both sides by 2, we get:

x = 32.5

So, the measure of angle C is 32.5 degrees, and the measure of angle D is 57.5 degrees.

The given vector has magnitude 54 units.

The vector is making an angle of 69° with the x-axis.

The horizontal component of the vector is

[tex] = 54 \cos(69) [/tex]

[tex] = 19.35[/tex]

To the nearest tenth, we have,

[tex] = 19.4[/tex]

The vertical component is

[tex] = 54 \sin(69 \degree) [/tex]

[tex] = 50.41[/tex]

[tex] = 50.4[/tex]

to the nearest tenth.

The required vector is

[tex]

\angle19.4,50.4 \: > [/tex]

The components of the vector with magnitude 54 and the angle of 69° from the horizontal can be written as <19.3519, 50.4133>.

What is a vector?

A vector is a quantity that has both magnitude and direction. It has two components a vertical component(Sine) and a horizontal component(Cosine). The component of a vector can be written as,

Vertical component, [tex]V_y = \vec V\ Sin(\theta)[/tex]

Horizontal component, [tex]V_x = \vec V\ Cos(\theta)[/tex]

We know that a vector can be divided into two components a horizontal component and a vertical component, therefore, the vector components can be written as,

[tex]V_y = \vec V Sin\theta\\\\V_y = 54\ Sin(69^o)\\\\V_y = 50.4133[/tex]

[tex]V_x = \vec V Cos\theta\\\\V_x = 54\ Cos(69^o)\\\\V_x = 19.3519[/tex]

Hence, the components of the vector with magnitude 54 and the angle of 69° from the horizontal can be written as <19.3519, 50.4133>.

Meis mothers is 4 times as old as mei. Mei’s mother is twice as old as mei’s mother.the sum of the three ages of 117. How old is mei, her mother, and her grandmother?

Answers

Mei is 9 years old, her mother is 36 and her grandmother is 72. 9+36+72= 117

Final answer:

Mei is 9 years old, her mother is 36 years old, and her grandmother is 72 years old, determined by defining variables for their ages and solving the equation based on their age relationships and the given total sum of their ages.

Explanation:

To solve the problem regarding the ages of Mei, her mother, and her grandmother, we can use a system of equations based on the information given. Let's define Mei's age as m, her mother's age as 4m (since her mother is 4 times Mei's age), and her grandmother's age as 8m (since the grandmother is twice as old as Mei's mother).

According to the problem, the sum of their ages is 117 years:

m + 4m + 8m = 117

Simplifying this equation gives us:

13m = 117

Next, we divide both sides by 13 to find m:

m = 117 / 13

m = 9

Now that we have Mei's age, we can easily calculate her mother's and grandmother's ages:

Mei's mother: 4m = 4(9) = 36 years oldMei's grandmother: 8m = 8(9) = 72 years old

Therefore, Mei is 9 years old, her mother is 36 years old, and her grandmother is 72 years old.

Imagine that you are pouring cement into cinder blocks to build a very sturdy wall. Each cinder block is 1.3 feet long, 0.67 feet high, and 0.67 feet wide. If 1 bag of cement is equivalent to 5 cubic feet, what is the number of bags of cement that you will need to fill the entire wall? Show the work

Answers

How many bricks are there or how many feet long and tall is it?

To find out how many cement bags are needed, calculate the volume of one cinder block and see how many such blocks fit in a cement bag. Then, divide the total number of cinder blocks by the number of blocks one bag can fill and round up to the nearest whole number.

To determine the number of cement bags needed to fill a cinder block wall with the given measurements, first calculate the volume of one cinder block. Then, figure out how many cinder blocks fit into one bag of cement.

The volume of one cinder block is:

V = length × height × width

V = 1.3 ft × 0.67 ft × 0.67 ft

V [tex]\approx[/tex] 0.5809 cubic feet

Now, since one bag of cement is equivalent to 5 cubic feet, determine how many cinder blocks one bag can fill:

Number of blocks per bag = 5 cubic feet / 0.5809 cubic feet per block

Number of blocks per bag [tex]\approx[/tex] 8.61 blocks

We need the total number of cinder blocks for the entire wall. Assuming we know the total wall dimensions, let's say we have a total of 100 blocks (for example purposes).

Total number of bags = Total number of blocks / Number of blocks per bag

Total number of bags = 100 / 8.61

Total number of bags [tex]\approx[/tex] 11.62

Since you can't buy a fraction of a bag, you would need to round up to the next whole number, so you would need 12 bags of cement to fill the wall.

Answers

x^3 - 64 = 0

We want to solve for x. Start by getting x by itself on one side.
We can do this by adding 64 to both sides of the equation.

x^3 = 64

Now, to get rid of the 3rd power that x is raised to, we can raise both sides to the 1/3 power

(x^3)^1/3 = 64^1/3

(x^3)^1/3 is the same as x

So x = 64^(1/3) and 64^(1/3) = 4

So x = 4 :)

Answers

12 boxes are needed and 20 will be in the last box.

1450/130 is 11.15 so You round up and need 12 boxes (because you can’t have .15 of a box) so you get the 11 boxes and multiply by how much it can hold (130) and get 1430 which is 20 short of 1450 so 20 would be in the last box .

We were told that, they sold some plants and now they have 21 plants left.

Let

represent the number of plants sold.

Then when we add the number of plants sold and the number left, we should get 45.

This implies that,

[tex]21 + p = 45[/tex]

This is Jamal's equation.

On the other hand, if we subtract the number of plants sold from the total number of plants, we should get 21. Thus,

[tex]45 - p = 21[/tex]

This is Asha's equation.
