A taxi driver's flat rate of $3 plus an additional $0.05 per mile car will only take taxi home if cost is under $10 under otherwise he will take the bus Carlos 15 miles from home explain how to write and solve an inequality determining if Carl will take the taxi for a bus
Step-by-step explanation:
we can model the expression for the inequality as
given the flat rate is $3
let the additional mile be x
hence
3+0.05x<10
step two:
let us proceed to solve for x
3+0.05x<10
0.05x<10-3
0.05x<7
divide both sides by 0.05
x<7/0.05
x<140
let us plug in 15 into the expression and see if the cost is under $10
3+0.05(15)<10
3+0.75<10
3.75<10
from the analysis, carl will have to take the taxi since cost is less than $10 i.e $3.75
Answer:
The inequality representing the situation is 0.5x + 3 < 10.
Use inverse operations and properties of inequality to solve.
Find that x < 14.
Carl lives 15 miles from home, so he will take a bus.

expand the brackets and collect like terms
5(3x-1)-3(5x-1)
- 2
Step-by-step explanation:Hi there !
5(3x - 1) - 3(5x - 1) =
= 15x - 5 - 15x + 3
= 15x - 15x + 3 - 5
= - 2
Good luck !
The expression 5(3x - 1) - 3(5x - 1) simplifies to -8 after using distributive property and adding like terms.
To expand the brackets and collect like terms in the expression 5(3x - 1) - 3(5x - 1).
Distribute the numbers outside the brackets to the terms inside the brackets:
5(3x - 1) - 3(5x - 1)
= 5×3x - 5 × 1 - 3 × 5x - 3 × 1
Perform the multiplication:
15x - 5 - 15x - 3
Collect like terms (combine the x terms and the constants):
=(15x - 15x) + (-5 - 3)
=0x - 8
Simplify:
-8
So, the expression 5(3x - 1) - 3(5x - 1) simplifies to -8.

A dairy company gets milk from two dairies and then blends the milk to get the desired amount of butterfat. Milk from dairy I costs $2.40 per gallon, and milk from dairy II costs $0.80 per gallon. At most $144 is available for purchasing milk. Dairy I can supply at most 50 gallons averaging 3.9% butterfat, and dairy II can supply at most 90 gallons averaging 2.9% butterfat. Answer parts a and b. a. How much milk from each supplier should the company buy to get at most 100 gallons of milk with the maximum amount of butterfat? The company should buy 40 gallons from dairy I and 60 gallons from dairy II. What is the maximum amount of butterfat? 330 gallons (Type an integer or a decimal.) b. The solution from part a leaves both dairy I and dairy II with excess capacity. Calculate the amount of additional milk each dairy could produce. The excess capacity of dairy I is 10 gallons, and for dairy II it is 30 gallons. Is there any way all this capacity
Answer:
a) i The company should buy 40 gallons from dairy I and 60 gallons from dairy
ii) What is the maximum amount of butterfat? The total amount of butterfat from Diary I and Diary II = 3.12% + 1.93%
=5.05%
b.The excess capacity of dairy I is 10 gallons, and for dairy II it is 30 gallons.
Step-by-step explanation:
a. How much milk from each supplier should the company buy to get at most 100 gallons of milk with the maximum amount of butterfat?
From the question, we are told that:
Milk from dairy I costs $2.40 per gallon, Milk from dairy II costs $0.80 per gallon.
Let's represent:
Number of gallons of Milk from dairy I = x
Number of gallons of Milk from dairy II = y
At most $144 is available for purchasing milk.
$2.40 × x + $0.80 × y = 144
2.40x + 0.80y = 144........ Equation 1
x + y = 100....... Equation 2
x = 100 - y
2.40(100 - y) + 0.80y = 144
240 - 2.4y + 0.80y = 144
-1.60y = 144 - 240
-1.6y = -96
y = -96/-1.6
y = 60
From Equation 2
x + y = 100....... Equation 2
x + 60 = 100
x = 100 - 60
x = 40
Therefore, since number of gallons of Milk from dairy I = x and number of gallons of Milk from dairy II = y
The company should buy 40 gallons from dairy I and 60 gallons from dairy
II. What is the maximum amount of butterfat?
From the question
Dairy I can supply at most 50 gallons averaging 3.9% butterfat,
50 gallons = 3.9% butterfat
40 gallons =
Cross Multiply
= 40 × 3.9/50
= 3.12%
Dairy II can supply at most 90 gallons averaging 2.9% butterfat.
90 gallons of milk = 2.9% butter fat
60 gallons of milk =
Cross Multiply
= 60 × 2.9%/90
=1.9333333333%
≈ 1.93%
The total amount of butterfat from Diary I and Diary II = 3.12% + 1.93%
=5.05%
b. The solution from part a leaves both dairy I and dairy II with excess capacity. Calculate the amount of additional milk each dairy could produce.
Excess capacity of Diary I =
50 gallons - 40 gallons = 10 gallons
Excess capacity of Diary II =
90 gallons - 60 gallons = 30 gallons
Therefore, the excess capacity of dairy I is 10 gallons, and for dairy II it is 30 gallons.

White shapes and black shapes are used in a game some are circles some are squares the ratio of white shapes to black shapes is5:11 the ratio of white circles to white squares are 3:7 the ratio of black circles to black squares are 3:8 work out what fraction of all the shapes are circles
Answer:
[tex]\frac{9}{32}[/tex]
Step-by-step explanation:
Given:
Ratio of white shapes to black shapes is 5:11
Ratio of white circles to white squares is 3:7
Ratio of black circles to black squares is 3:8
To find: fraction of all the shapes that are circles
Solution:
As ratio of white shapes to black shapes is 5:11,
let number of white shapes be 5 k and number of black shapes by 11 k
As ratio of white circles to white squares is 3:7,
Number of white circles = [tex]\frac{3}{10}(5k)=\frac{3}{2}k[/tex]
Number of white squares = [tex]\frac{7}{10}(5k)=\frac{7}{2}k[/tex]
As ratio of black circles to black squares is 3:8,
Number of black circles = [tex]\frac{3}{11} (11k)=3k[/tex]
Number of black squares = [tex]\frac{8}{11}(11k)=8k[/tex]
Total number of circles = [tex]\frac{3}{2}k+3k=\frac{9}{2} k[/tex]
Total number of shapes = [tex]5k+11k=16k[/tex]
Therefore,
Fraction of circles [tex]=\frac{\frac{9}{2} k}{16k} =\frac{9}{32}[/tex]

f (x) = -2x + 1, find f (1/2)
Answer:
[tex]f(1/2)=0[/tex]
Step-by-step explanation:
So we have the function:
[tex]f(x)=-2x+1[/tex]
And we want to find f(1/2).
So, substitute 1/2 for x:
[tex]f(1/2)=-2(\frac{1}{2})+1[/tex]
Evaluate. Multiply:
[tex]f(1/2)=-1+1[/tex]
Add:
[tex]f(1/2)=0[/tex]
So, our answer is:
[tex]f(1/2)=0[/tex]
And we're done!

what is an example of dilation in the real world?
I need the area of this shape please explain.
Answer:
130'²
Step-by-step explanation:
step 1) work out area of whole trapezium:
((a+b) x h) / 2
a and b are the two parallel sides
h is the perpendicular height (8)
a = 4+4+3 = 11
b = 23
a + b = 11 + 23 = 34
(a + b) x h = 34 x 8 = 272
272 / 2 = 136²
step 2) work out the area of rectangle
2 x 3 = 6²
step 3) take area of rectangle away from area of whole trapezium
136 - 6 = 130
130' ²
