Answer:

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]

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.

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

Answer:

Olga

Step-by-step explanation:

To calculate average speed we can compare their hourly rate

Trisha ran 10km in 2.5 hours which is equal to 4km in an hour

Jason ran 7.5km in 2 hours which is equal to 3.75km an hour

Olga ran 9.5km in 2.25 hours which is equal to 4.2 an hour approximately

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!

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.

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.
