16/35
Give your answer in its simplest form.
Answer:
2/5 thats the answer i think
Answer:
2/5
Step-by-step explanation:
[tex]\frac{7}{8}[/tex]×[tex]\frac{16}{35}[/tex]
7×16=112
8×35=280
Simplify:
[tex]\frac{112}{280}[/tex] 112÷4=28 280÷4=70

Doug's Pizza Shop sells pizza for $12plus $3per topping "t". Jake'sPizza Shop sells pizza for $17plus $2per topping "t". Write an equation that willtell you how many toppings need to be on a pizza from each pizza place to make their pizza the same price.
Answer:
5 toppings
Step-by-step explanation:
Given that :
Doug's pizza:
Sales price of pizza :$12 plus
Topping (t) = $3 per topping
Jake's pizza:
Sales price of pizza :$17 plus
Topping (t) = $2 per topping
To make their pizza the same price, how many topping needs to be on a pizza of each
12 + 3t = 17 + 2t
3t - 2t = 17 - 12
t = 5
5 toppings each
find the sum of the series 9+3+1+........+1/27
Answer:
364/27
Step-by-step explanation:
9, 3, 1, ... is a geometric sequence with common ratio r = 1/3.
The nth term is a1rn-1.
If a1rn-1 = 1/27, then 9(1/3)n-1 = 1/27
32(3-1)n-1 = 3-3
3231-n = 3-3
33-n = 3-3
3-n = -3
n = 6
The sum, Sn, of the first n terms of a geometric sequence is given by Sn = a1(1 - rn) / (1 - r).
So, 9 + 3 + 1 + ... + 1/27 = S6 = 9(1 - (1/3)6) / (1 - 1/3)
= 9(1 - 1/729) / (2/3)
= (27/2)(728/729) = 364/27

distribute then solve two-step = to get z
4(2z-5)=-4
x = 2
Step-by-step explanation:
math lol
I'm truly deeply sorry if its wrong :'))
Answer:
z = 2
Step-by-step explanation:
Given
4(2z - 5) = - 4 ← distribute parenthesis on left side by 4
8z - 20 = - 4 ( add 20 to both sides )
8z = 16 ( divide both sides by 8 )
z = 2
A train leaves New Delhi at 4:00 p.m. and reaches Lucknow at midnight. Its speed is 55km/h. What is the distance between Delhi and Lucknow?
Answer:
[tex]\boxed{440 km}[/tex]
Step-by-step explanation:
→ Work out time between New Delhi and Lucknow
12:00 - 4:00 = 8:00
→ State the speed formula
Speed = Distance ÷ Time
→ Rearrange to make distance the subject
Distance = Speed × Time
→ Substitute in the values
55 × 8 = 440 km

In New York, state sales tax rates vary by county. In Allegany County, the sales tax rate is 8 1 2 %. a. A book costs $12.99, and a video game costs $39.99. Rounded to the nearest cent, how much more is the tax on the video game than the tax on the book?
Answer:
$ 2.30
Step-by-step explanation:
Given that the sales tax rate [tex]= 8\frac{1}{2}\%=8.5\%[/tex]
The cost of the book is $ 12.99.
So, the tax on the book= 8.5% of 12.99
[tex]= \frac {8.5}{100}\times 12.99[/tex]
=1.10
So, the sales tax on the book is $ 1.10.
The cost of the video game is $ 39.99.
So, the tax on the book= 8.5% of 39.99
[tex]= \frac {8.5}{100}\times 39.99[/tex]
=3.30
So, the sales tax on the book is $ 3.40.
The difference of taxes on both the items = $ 3.40-$ 1.10=$ 2.30
So, the tax on the video game is $ 2.30 more than then tax on the book.
You work in a grocery store warehouse recording shipments. A driver delivers 25 crates of strawberries for distribution. A store calls needing seven crates of strawberries. After you fill this order, how many crates of strawberries are available for other stores?
Answer:
18 crates
Step-by-step explanation:
Data provided in the question
The Number of strawberries for distribution delivered is 25 crated
Now he seven crates is required
So the remaining crates left is
= 25 - 7
= 18 crates
hence, after filling the order the number of order crates of strawberries is 18 crates and the same is to be considered

Answer: n + (n + 2) = 84
Step-by-step explanation:
If n is the smallest integer, the other integer must be two more than that, because it has to be odd. The two numbers add up to 84, so the other side of the equation is 84.
Answer:
41 and 43.
Step-by-step explanation:
We can divide 84 by 2 and add and subtract 1 from the result to get 41 and 43 as the two numbers. For any number n that is divisible by 2, we can solve this problem by finding n/2 + 1 and n/2-1. These will always be consecutive odd numbers and if you add them up, you get n.

Can you explain why a larger denominator actually means the fraction is smaller than a fraction with a smaller denominator? Why is it helpful to know how to compare and order fractions? Can you think of situations where you will need to compare and/or order fractions?
Answer:
It is helpful to know how to compare and order fractions because when doing division between different groups or classes it is easy to determine their share and so on.
Step-by-step explanation:
Suppose we have two fractions 1/2 and 1/3 . And suppose we have two cakes of equal sizes. We cut the first cake into 2 equal parts and the 2nd cake into three equal parts.
Now comparing both the cakes the cake with two pieces will have a larger piece as compared to the cake having three pieces.
So 1/2 > 1/3
or half of the cake is greater than one third of the cake.
The larger denominator means a smaller fraction because it shows greater number of divisions. Like wise a fraction with smaller denominator is a larger fraction as it shows smaller number of divisions.
It is helpful to know how to compare and order fractions because when doing division between different groups or classes it is easy to determine their share and so on.
It can be employed between the different groups and to find different rates / scores or for statistical calculations etc.
In finding the order of division and so on.

Two sides of a triangle are equal in length and double the length of the shortest side. The perimeter of the triangle is 36 inches. Select the equation that most accurately depicts the word problem
A:x+2x^2=36
B:x+x+2x=36
C:2x+2x+2x=36
D:x+2x+2x=36
Answer:
Answer is below
Step-by-step explanation:
To solve this, you can set up an equation. Make the length of the shortest side x, so the 2 sides double the length will equal 2x. Since they all equal the perimeter of 36, do x + 2x + 2x =36. These values all represent the sides(2 longer, one short). Combine like terms to get 5x=36 then divide by 5 to find the value of x. x=7.2in meaning the shorter side is 7.2 inches while the longer sides are both 14.4 inches each since they are double in size.
Answer:
D:X+2X+2X=36
Step-by-step explanation:
X+X=EQUAL AND DOUBLE THE SHORTEST SIDE
2[X+X]+[X]=36

6x+13=9x-8
Step-by-step explanation:
Hey there!
Given;
6x + 13 = 9x - 8
Shift "6x" to right side and "-8" to left side and simplify it to get answer.
13+8 = 9x-6x
21 = 3x
x= 21/3
Therefore, x= 7.
