Step-by-step explanation:
Choose all the expressions that are equal to 34 × 8,010.
A. 8,010 × 34
B. 34 × (801 × 102)
C. 30 × 4 × 8,010
D. 34 × (8,000 + 10)
E. (30 + 4) × 8,010
Answer: A. 8,010 × 34
D. 34 × (8,000 + 10)
E. (30 + 4) × 8,010
Step-by-step explanation:
First we need to calculate 34 × 8010 = 272340
A. 8,010 × 34 = 272340
This is equal to 34 × 8010.
B. 34 × (801 × 102)
= 34 × 81702
= 2777868
This is not equal to 34 × 8010.
C. 30 × 4 × 8,010
= 961200
This is not equal to 34 × 8010.
D. 34 × (8,000 + 10)
= 34 × 8010 = 272340
This is equal to 34 × 8010.
E. (30 + 4) × 8,010
= 34 × 8010 = 272340
This is equal to 34 × 8010.
Therefore, the correct options are:
A, D, E.

The diagram shows a periscope used to see objects that are behind or under a barrier. What makes it possible to see an object when looking through a periscope? The periscope –
A. contains mirrors that reflect the object
B. magnifies small objects so they can be seen
C. absorbs the light rays passing through it
D. separates the light into different colors
Answer: A. contains mirrors that reflect the object
Step-by-step explanation:
A periscope contains mirrors in it that are on opposite sides and are arranged in a 45° angle to each other. It works by light striking the first mirror which cause its to reflect it at a 45° angle to the next mirror.
Depending on the length of the periscope, this continues until the last mirror reflects the incoming light to the eyes of the person using the periscope thereby allowing them to see objects hidden behind or under a barrier.

Answer:
x = -7º
x+59 = 52º
x+51 = 44º
Step-by-step explanation:
84 + (x+59) + (x+51) = 180º
180 - 84 = 96
x+59 + x+51 = 96
2x + 110 = 96
2x = -14
x = -7
proof:
-7+59 = 52º
-7+51 = 44º
the sum of angles in a triangle must be 180º so:
84 + 52 + 44 = 180
Answer:
∠A = 44°Step-by-step explanation:
84 + x + 59 + x + 51 = 180
2x = 180 - 84 - 59 - 51
x = -14/2
x = -7
∠A = x + 51
∠A = -7 + 51
∠A = 44°

an equation of the line that passes through (3, 1) and (0, 10).
Answer:
So the equation of the line that passes through (3, 1) and (0, 10) is y=-3x+10
Step-by-step explanation:
(3, 1) and (0, 10)
m=y²-y¹/x²-x¹
m=10-1/0-3
m=9/-3
m=-3
y=mx+b
y-y=m(x-x1)
y-1=-3(x-3)
y-1=-3x+9
+1 +1
y=-3x+10
Muriel says she has written a system of two linear equations that has an infinite number of solutions. One of the equations of the system is 3y = 2x – 9. Which could be the other equation?
2y = x – 4.5
y = x – 3
6y = 6x – 27
y = x – 4.5
Answer: B
Step-by-step explanation: If you divide the 3 Y to get Y by itself, you will divide 3 on both sides. So 2X/3=2X/3 and -9/3=-3
So it will be Y=2X/3-3
slove the equation f-(-4)=12.
f =-8.
f =16.
f =8.
f = -9
Step-by-step explanation:
f-(-4)=12(Remove brackets)
f--4=12(Negative and negative is going to give you positive)
f+4=12(Group Like Terms)
f=12-4(Subtract)
f=8
Then that will be the final answer
Answer:
[tex]\huge\boxed{f=8}[/tex]
Step-by-step explanation:
[tex]f-(-4)=12\to f+4=12\qquad|(-)(-)\to(+)\\\\f+4=12\qquad|\text{subtract 4 from both sides}\\\\f+4-4=12-4\\\\f=8[/tex]

Answer) 0.5
Zach has a z-score of –1.5. His height is
Answer) 46 inches.
Approximately 16 % of 7-year-old children are taller than 51 inches.
In the United States, birth weights of newborn babies are approximately normally distributed with a mean of μ = 3,500 g and a standard deviation of σ = 500 g.
What percent of babies born in the United States are classified as having a low birth weight (< 2,500 g)? Explain how you got your answer.
(Answers)
The z-score for 2,500 g is –2.
According to the empirical rule, 95% of babies have a birth weight of between 2,500 g and 4,500 g.
5% of babies have a birth weight of less than 2,500 g or greater than 4,500 g.
Normal distributions are symmetric, so 2.5% of babies weigh less than 2,500g.
At a little-known vacation spot, taxi fares are a bargain. A 14 Mile Taxi ride takes 16 minutes and costs 11.20 you want to find the cost for a 49 mile taxi ride
Answer:
the unit price needed to calculate is $0.8 per mile
Step-by-step explanation:
Here is the complete question:
At a little-known vacation spot, taxi fares are a bargain. A 14 Mile Taxi ride takes 16 minutes and costs $11.20 you want to find the cost for a 49 mile taxi ride . What unit price do you need?
Step-by-step explanation:
To determine the unit price needed to calculate the cost for a 49 mile taxi ride, we will determine the cost of the ride per mile. To do this, let the cost per mile be $x
If it cost $11.20 for a 14 mile ride
Then, it will cost $x for a 1 mile ride
∴ x = (1 × 11.20) / 14 = 0.8
x = 0.8
The taxi ride costs $0.8 per mile.
Hence, the unit price needed to calculate is $0.8 per mile.
If desired,
To find the cost for a 49 mile taxi ride, multiply the distance traveled by the unit price,
Distance = 49 mile
Unit price = $0.8 per mile
∴ Cost for a 49 mile taxi ride = 49 × $0.8
Cost for a 49 mile taxi ride = $39.2
Hence, the cost for a 49 mile taxi ride is $39.2

A and B are postive integers such that 1/a + 1/b +1/ab = 1. Find ab
Answer: ab =6
have:
[tex]\frac{1}{a}+\frac{1}{b}+\frac{1}{ab}=1\\\\=>\frac{b}{ab}+\frac{a}{ab}+\frac{1}{ab}=1\\\\<=>\frac{a+b+1}{ab}=1[/tex]
=> a + b + 1 = ab
⇔ a + b + 1 - ab = 0
⇔ b - 1 - a(b - 1) + 2 = 0
⇔ (b - 1)(1 - a) = -2
because a and b are postive integers => (b - 1) and (1 - a) also are integers
=> (b - 1) ∈ {-1; 1; 2; -2;}
(1 -a) ∈ {-1; 1; 2; -2;}
because (b -1).(1-a) = -2 => we have the table:
b - 1 -1 1 2 -2
1 - a 2 -2 -1 1
a -1 3 2 0
b 0 2 3 -1
a.b 0 6 6 0
because a and b are postive integers
=> (a;b) = (3;2) or (a;b) = (2;3)
=> ab = 6

Answer:
Step-by-step explanation:
The thing you have to realize is that the diagonals of a parallelogram bisect each other. So DF = BF. With that fact, you get
4y + 19 = 10y - 11 Add 11 to both sides
4y+19+11 = 10y-11+11 Combine
4y + 30 = 10y Subtract 4y
4y-4y +30 = 10y - 4y Combine
30 = 6y Divide by 6
y = 30/6
y = 5

Three friends are starting a new exercise equipment franchise. Their investments are in the ratio of 5:7:11. The smallest investor is contributing $75,000. What is the largest investor contributing?
Given:
Ratio of investments are 5:7:11.
Contribution of smallest investor = $75,000
To find:
The contribution of largest investor.
Solution:
Let the contribution of three friends be 5x, 7x and 11x respectively.
Here, 5x is smallest and 11 is largest.
The smallest investor is contributing $75,000.
[tex]5x=75000[/tex]
Divide both sides by 5.
[tex]x=15000[/tex]
Now,
[tex]\text{Contribution of largest investor}=11x[/tex]
[tex]\text{Contribution of largest investor}=11(15000)[/tex]
[tex]\text{Contribution of largest investor}=165000[/tex]
Therefore, the contribution of largest investor is $165,000.

plz help An online store advertises 40% off all items and free shipping. Gretta orders a pair of shoes originally priced at $65 and pays an 8% sales tax. How much will Gretta pay in total for this transaction? Show the steps you used to arrive at your solution in a clear, organized response.
Answer:
$42.12
Step-by-step explanation:
The original price of the shoes was $65.
Everything is 40% off. Therefore, the new price of the shoes now will be the original price minus 40% of 65.
40% of 65 is 0.4(65) or $26. So, $26 was deducted.
This means that the new price will be $65-$26 or $39.
There’s also an 8% sales tax that will be applied. So, Gretta’s total will be the new price of the shoes plus the sales tax being applied to the shoes.
The sales tax is 8% of 0.08. So, when applied to the shoes, it will be: 0.08(39) or $3.12.
Therefore, the total sum Gretta will pay is $39 (the new price) + $3.12 (the sales tax) for a grand total of $42.12
