Answer:
Computing the sum of $5.89 and $1.45 we get: $7.34
Step-by-step explanation:
We need to explain, how can we compute the sum of $5.89 and $1.45?
Computing the sums of dollar amounts is same as computing the sum of simple decimal expressions. Each value will be added to its corresponding values and we will get the answer.
Computing the sum of $5.89 and $1.45
[tex]\:\:\:\:\:\$ \:\:5.89\\+\$ \:\:1.45\\------\\\:\:\:\:\:\$ \:\:7.34[/tex]
So, we will start adding from right side, 9 will be added with 5 and we get 14, 1 will be given carry and 8 will be added by 4 and add the carry we get 13, 1 will be given carry and 1 will be added by 5 and add the carry we get 7
So, Computing the sum of $5.89 and $1.45 we get: $7.34
Jeff divided his 1,200 stamps equally among 7 stamp albums. Were there any stamps left over?
If so, how many?
Yes; there was 1 stamp left over.
Yes; there were 3 stamps left over.
Yes; there were 10 stamps left over.
No; there were no stamps left over.
Answer:
3 stamps were left over
Step-by-step explanation:
Division
When a number m divides evenly by n the remainder is 0. For example, 120 divides exactly by 30 because 120/30=4 and the remainder is 0.
But 120 does not divide exactly by 50 because 120/50 = 2 and leaves a remainder of 20.
Jeff divided his 1,200 stamps equally among 7 stamp albums. If the division of 1,200 by 7 was exact, there won't be any stamp left over. Let's test it.
1,200/7 is 171.4, obviously is not exact, thus There were stamps left over.
How many?
Multiply the lower integer of division 171 by 7 to get: 171*7 =1,197. This means that 1,200-1,197= 3 stamps were left over

Prove each of the following statements about integers by proving thecontrapositive of the statement.A. If 3nis even, thennis even.B. Ifx y zis odd, then at least one ofx; yandzis odd.
Answer and Step-by-step explanation:
(A) Suppose 3n is even, this implies that the product of 3n is a multiple of two, let's say 2(3k) where k is a real number. Rearranging that, we have 3(2k), let 2k = n. Therefore, n is even.
(B) Suppose xyz is odd, then let x = 2k, y = 2p + 1 and z = 2q + 1. xyz = 2k(2p + 1)(2q + 1) and this is obviously even since it is a multiple of 2.

2(2x+4)-3x=12
Answers
x=4
x=8
4
12
Answer: 4
Step-by-step explanation:
first you remove the parentheses it should look like this (4x+8-3x=12) then you collect the like terms (like terms have the same variable to the same power) it should look like this(x+8=12). then you move the constant to the right then last you calculate it should look like this x=12-8). then you subtract 12 by 8 and 4 is what you get.
One-hour carbon monoxide concentrations in air samples from a large city average 12 ppm (parts per million) with standard deviation 9 ppm.
Required:
a. Do you think that carbon monoxide concentrations in air samples from this city are normally distributed.
b. Find the probability that the average concentration in 100 randomly selected samples will exceed 14 ppm.
Answer:
0.0132
Step-by-step explanation:
No
Carbon monoxide concentrations sample in air from a large city are not normally distributed. This is often so because of the time of the day and that of the night. There exists different concentrations during the day, with respect to during the night. The companies and factories work during the day, so does most vehicles. This means that there tend to be a higher concentration during the day, than there will be during the night.
b)
Assuming that Y' is approximately normal, we can say that
P(Y' > 14) = P(Z > [√100(14 - 12)/9]) and this is equal to
P(Z > 2.22) = 0.013

A person takes up 18 inches of space on a stadium bleacher. If one row of bleachers is 100 feet long and
there are 20 rows of bleachers, how many people can fit into the stands?
The number of people who can fit into the stands in the stadium is 1,333 people
Number of people in the stadiumSpace taken by each person = 18 inches
Length of a row of bleachers = 100 feet
Rows of bleachers = 20
Conversion of feet to inches1 feet = 12 inches
100 feet = 1200 inches
Number of people per row = 1200 inches ÷ 18 inches= 66.67 people
Number of people that fits the stand = Number of people per row × Rows of bleachers= 66.67 × 20
= 1,333.4
Approximately,
1,333 people can fit into the stands in the stadium

A rectangle has a length of x +5 and a width of

of the rectangle in terms of x.
A = 2x + 12
b. A= 2x - 2
A=x2 + 12x - 35
d. A=x? - 2x - 35
Answer:
A=x2 - 2x -35
Step-by-step explanation:
x+5 x-7
The solution is Option D.
The area of the rectangle is A = x² - 2x - 35
What is the Area of a Rectangle?
The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle
Area of Rectangle = Length x Width
Given data ,
Let the area of the rectangle be represented as A
Now , the value of A is
The length of the rectangle L = x + 5
The width of the rectangle is W = x - 7
And ,
The area of rectangle = L x W
Substituting the values in the equation , we get
The area of rectangle = Length of rectangle x Width of rectangle
The area of rectangle = ( x + 5 ) ( x - 7 )
On simplifying the equation , we get
The area of rectangle A = x ( x - 7 ) + 5 ( x - 7 )
The area of rectangle A = x² - 7x + 5x - 35
The area of rectangle A = x² - 2x - 35
Therefore , the value of A is x² - 2x - 35
Hence , the area of rectangle is x² - 2x - 35

Answer:
x = 20
Step-by-step explanation:
First, we need to combine both equations as we know they are create a "straight angle", which is 180 degrees:
2x + 8 + 6x + 12 = 180
Next, we can combine like terms to simplify the equation:
8x + 20 = 180
Now, we can subtract 20 from each side:
8x = 160
Finally, we divide both sides by 8 to find the value of "x":
x = 20

A bus travels at a constant speed of 48 km/h. How long will it take to travel 600 km?
Answer:
It will take 12 and 30 hours
Step-by-step explanation:
To solve this, you need to divide by distance needed to travel by the speed
600/48 is equal to 12.5 hours.
.5 hours is equal to 30 mins because 60mins times .5 is 30 minutes, therefore the final answer is 12.5 hours

Step-by-step explanation:
[tex]6z-7=2z-2\qquad|\text{add 7 to both sides}\\\\6z-7+7=2z-2+7\\\\6z=2z+5\qquad|\text{subtract}\ 2z\ \text{from both sides}\\\\6z-2z=2z-2z+5\\\\4z=5\qquad|\text{divide both sides by 4}\\\\\dfrac{4z}{4}=\dfrac{5}{4}\\\\\boxed{z=\dfrac{5}{4}}[/tex]
Answer: z = 5/4
Step-by-step explanation: First simplify the equation by subtracting 2z from both sides and adding 7 to both sides to get 4z = 5.
Step by step below
6z -7 = 2z -2
-2z -2z
4z -7 = -2
+7 +7
4z = 5
Now divide both sides by 4 to get z = 5/4
4z/4 = 5/4
z = 5/4

Answer:
x= 5; Segment QR is the mid segment and YW is the base of the triangle. Mid segments are half the length of the base.
Step-by-step explanation:
2x - 3 = (x + 9) ÷ 2 Multiply both sides by 2
(2x - 3) • 2 = x + 9
4x - 6 = x + 9 Add 6 to both sides
4x = x + 9 + 6
4x = x + 15 Subtract x from both sides
4x - x = 15
3x = 15 Divide 3 on both sides
x = 15/3
x = 5

Brody is going to invest in an account paying an interest rate of 3.7% compounded monthly. How much would Brody need to invest, to the nearest hundred dollars, for the value of the account to reach $34,000 in 13 years?
Answer:
21000
this is the answer
The value of the account is to reach $34,000 in 13 years with a rate of 3.7 compounded monthly is $ 21,000.
What is compound interest?Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.
Brody is going to invest in an account paying an interest rate of 3.7% compounded monthly.
The rate of interest yearly will be
[tex]\rm Yearly \ rate = \dfrac{3.7}{12}\\\\Yearly \ rate = 0.308 \%[/tex]
The value of the account is to reach $34,000 in 13 years.
Amount (A) = $ 34,000
Time (t) = 13 years
Rate (r) = 0.308 %
Then the principal amount will be
[tex]\begin{aligned} A &= P (1 + \dfrac{r}{100})^{12*t}\\\\34000 &= P (1 + \dfrac{0.308}{100}) ^{13 * 12}\\\\34000 &= P (1.00308)^{156}\\\\P &= 21,044 \approx 21,000 \end{aligned}[/tex]
The principal amount is $21,000.
