Answer:
x ≥ 1
Step-by-step explanation:
3 + 4x ≥ 7
3 - 3 + 4x ≥ 7 - 3
4x ≥ 4
4x / 4 ≥ 4 / 4
x ≥ 1
Tyler bought shoes for $72. The next week he noticed that the price went
up to $87. What was the percent increase (percent change)? Round your
answer to the nearest whole percent. *
Answer:
Percent increase is 21%
Step-by-step explanation:
Initial cost of shoes = $72
New price of shoes = $87
Increase in price of shoes = New price of shoes - Initial cost of shoes
= [tex]87-72[/tex]
= $15
Percentage increase in price of shoes = ( Increase in price of shoes ÷ Initial cost of shoes) × 100
= [tex]\frac{15}{72}(100)=20.8\%[/tex]
≈ 21%
So, percent increase is 21%
Is f<12 true or false
6) You go to dinner with some
friends. Your total bill was $56.32.
You have a coupon for 15%. How
much is your total cost if you leave
a 20% tip?
Answer:
$57.44
Step-by-step explanation:
1. subtract 15% from the bill with coupon:
$56.32 - ($56.32 x 0.15) = $47.87
2. add 20% to this new bill:
$47.87+(47.87 x 0.20) = $57.44
pls help me and show world pls :)
Answer:
add equation 2 from equation 3
Step-by-step explanation:
So, we are given equations 1, 2, and 3, but for this problem, we need to use just 2 and 3.
4x - 2y = -16
x + 2y = 6
In order to eliminate one variable, then we need to find whether there are two numbers that have the same coefficient (or multiply one by a number to make it) so that if you add/subtract two numbers, it gives you 0. So, in this problem, if you add
2y to -2y, then it gives you 0, which means that y would be canceled out.
So, the answer is the first option.
Feel free to ask any questions about clarity! (this explanation is pretty bad, but I can explain it more if you want) :D

Answer:
175
Step-by-step explanation:
hey! so it's basically an "estimate" meaning that you can round all the measurements up to the nearest whole number. and since finding the prism's volume is l*h*w divided by 2, i did 7*5*10 and got 350. half of 350 is 175 which is the volume of the prism :)
Answer:
175
Step-by-step explanation:
the formula of triangular prism is
v = 1÷2( b×h×l)
base (b) =5.1cm
height( h) = 6.9
length ( l) = 9.9
v =1÷2 ( 5.1 × 6.9× 9.9 )
v = 174.19 cm^3
so th closest will be 175cm^3
Using long division to find the quotient, what changes do you first
need to make to the dividend (125x3 - 8)?
(125x3 – 8) = (5x – 2)
Answer:
[tex]\frac{125x^3 - 8}{5x - 2} = 25x^2 + 10x +4[/tex]
Step-by-step explanation:
Given
[tex]Dividend = 125x^3 - 8[/tex]
[tex]Divisor = 5x - 2[/tex]
Required
Determine the quotient
See attachment for complete process.
First, divide 125x^3 by 5x
[tex]\frac{125x^3}{5x} =25x^2[/tex]
Write [tex]25x^2[/tex] at the top
Multiply [tex]5x - 2[/tex] by [tex]25x^2[/tex]
[tex]= 125x^3 - 50x^2[/tex]
Subtract from 125x^3 - 8
i.e.
[tex]125x^3 - 8 - (125x^3 - 50x^2) = 50x^2 - 8[/tex]
Step 2:
Divide 50x^2 by 5x
[tex]\frac{50x^2}{5x} = 10x[/tex]
Write [tex]10x[/tex] at the top
Multiply [tex]5x - 2[/tex] by [tex]10x[/tex]
[tex]= 50x^2 - 20x[/tex]
Subtract from 50x^2 - 8
i.e.
[tex]50x^2 - 8 - (50x^2 - 20x) = 20x - 8[/tex]
Step 3:
Divide 20x by 5x
[tex]\frac{20x}{5x} = 4[/tex]
Write [tex]4[/tex] at the top
Multiply [tex]5x - 2[/tex] by [tex]4[/tex]
[tex]= 20x - 8[/tex]
Subtract from 20x - 8
i.e.
[tex]20x - 8 - (20x - 8) = 0[/tex]
Hence:
[tex]\frac{125x^3 - 8}{5x - 2} = 25x^2 + 10x +4[/tex]

Miki already knew 4 appetizer recipes before starting culinary school, and she will learn 1 new appetizer recipe during each week of school. Write an equation that shows the relationship between the number of weeks x and the number of appetizer recipes y.
Answer:
y = 4 + x
Step-by-step explanation:
Appetizer recipe Miki knows already = 4
Appetizer recipe learnt per week = 1
x = number of weeks
y = total number of appetizer recipes Miki knows
Equation that shows the relationship between the number of weeks x and the number of appetizer recipes y
y = 4 + x

Answer:
[tex]\sqrt{0.5}[/tex]
Step-by-step explanation:
cosx=adj/hyp
adj= [tex]\sqrt{2}[/tex]/2
hyp= r
cos(45)= ([tex]\sqrt{2}[/tex]/2)/r
[tex]\sqrt{2}[/tex]/2 = ([tex]\sqrt{2}[/tex]/2)/r
multiply both sides by r
([tex]\sqrt{2}[/tex]/2)r = [tex]\sqrt{2}[/tex]/2
divide both sides by [tex]\sqrt{2}[/tex]/2
r = 1
pythagorean theorem: [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
a = [tex]\sqrt{2}[/tex]/2
b = y
c = r = 1
[tex](\sqrt{2}/2)^{2}[/tex] + [tex]y^{2}[/tex] = [tex]1^{2}[/tex]
[tex](\sqrt{2}/2)^{2}[/tex] = 2/4 = 0.5
0.5 + [tex]y^{2}[/tex] = 1
subtract 0.5 from 1
[tex]y^{2}[/tex] = 0.5
[tex]\sqrt{y^{2}}[/tex] = [tex]\sqrt{0.5}[/tex]
y = [tex]\sqrt{0.5}[/tex]

Julie says that the most amount of time spent on homwork is 1 1/2 times the least amount of time spent on homwork who is correct explain
Required Data :
1 3/4, 2 1/2, 2, 2 3/4, 1, 1 3/4, 1 1/4, 3, 3 1/4, 3 3/4, 2, 2
Answer:
Julie is Incorrect
Step-by-step explanation:
Given the data:
1 3/4, 2 1/2, 2, 2 3/4, 1, 1 3/4, 1 1/4, 3, 3 1/4, 3 3/4, 2, 2
Arrangement in ascending order :
1, 1 1/4, 1 3/4, 1 3/4, 2, 2, 2, 2 1/2, 2 3/4, 3, 3 1/4, 3 3/4.
The least amount of time spent is : 1
The most amount of time spent is : 3 3/4
From Julie's assertion, that the most amount of time spent is equal to 1 1/2 the least amount of time spent.
Most amount of time = 1 1/2 * least amount of time
3 3/4 = 1 * 1 1/2
15/4 = 3/2
However, 15/4 ≠ 3/2
Hence, Julie is incorrect

Answer:
0.527
Step-by-step explanation:
From the question,
The sequence is Geometry Progression (G.P)
Tₙ = arⁿ⁻¹.......................... Equation 1
Where n = number of term, a = first term, r = common ratio
Given: n = 7, a = 6, r = 2/3
Substitute these values into equation 1
T₇ = 6(2/3)⁷⁻¹
T₇ = 6(2/3)⁶
T₇ = 6(64/729)
T₇ = 384/729
T₇ = 0.527
Hence, the 7th term of the sequence is 0.527

Which equation represents the proportional relationship between the cost, t, in dollars, of p pounds of wood bought? T=0.29pt = 0.29 p t=0.31pt = 0.31 p t=3.45pt = 3.45 p t=3.48p
Answer:
T = 0.29p
Step-by-step explanation:
From the table Given :
We can obtain the uint cost per pound of wood :
Cost of 12 pounds of wood = $3.48
Cost per pound = Cost / weight
Cost per pound = $3.48 / 12 = $0.29
Hence, the proportional relationship cost, T in dollars and p pounds of wood is ;
Cost = unit cost per pound * number of pounds
T = 0.29 * p
T = 0.29p
Subtract. Write your answer in simplest form.
