Answer: The proportion of businesses who did not respond = 54.67%

Step-by-step explanation:

Given : Total businesses = 150

Businesses responded = 68

Businesses did not respond =  150- 68 = 82

The proportion of businesses who did not respond =

[tex]\dfrac{\text{Businesses did not respond}}{\text{Total businesses}}\times100[/tex]

[tex]=\dfrac{82}{150}\times100=54.67\%[/tex]

Hence, the proportion of businesses who did not respond = 54.67%

Answer:

$4800

Step-by-step explanation:

you multiply the 8 and 3 together then multiply what you got for 3 x 8 multiply that by 200

Answer:

$253.35

Step-by-step explanation:

A=200(1+0.03)^8

A=253.35

Answer:

No, Barbra is wrong as cost of 1 loaf of bread is £1.50 not $1.40.

Step-by-step explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

Barbara buys 3 boxes of eggs costing £1.20 each

1 jar of mayo costing £1.80

2 loaves of bread

she pays £10 note and gets £1.60 change

Barbara works out the cost of 1 loaf of bread as £1.40.

Is she correct? You MUST show your working out.

The explanation of the answer is now given as follows:

Total cost of 3 boxes of eggs = Number of boxes of eggs bought * Price per box of egg = 3 * £1.2 = £3.60

Cost of 1 jar of mayo = £1.80

Total amount spent = Note paid - Change collected = £10 - £1.60 = £8.40

Total cost of 2 loaves of bread = Total amount spent - Total cost of 3 boxes of eggs - Cost of 1 jar of mayo = £8.40 - £3.60 - £1.80 = £3.00

Cost of 1 loaf of bread = Total cost of 2 loaves of bread / 2 = £3.00 / 2 = £1.50

Therefore, Barbra is wrong as cost of 1 loaf of bread is £1.50 not $1.40.

The second option

Step-by-step explanation:

180-45 because thats how you find missing angles on a straight angle.

Answer:

y=-2x-1

Step-by-step explanation:

Answer: y = -2x - 1

Step-by-step explanation:

Step-by-step explanation:

Given that,

12 over 30 and 18 over 45

We need to tell whether the ratios are Proportional or Not Proportional.

[tex]\dfrac{12}{30}=\dfrac{2}{5}[/tex]

And

[tex]\dfrac{18}{45}=\dfrac{2}{5}[/tex]

The ratio for both fraction is same i.e. 2/5 Hence, each ratios are Proportional.

Hey you were the one I helped before right?

Well I guess I can't stop u from giving doubts. Anyway, I'll give I the answer for this one as well.

Hope this helped (again lol), U can ask for help anytime.

Don't forget to give thanks.

Answer:

y = 5/4 (x) + 7

Explanation:

Slope of a line (m): (y₂ - y₁) ÷ (x₂ - x₁)

       Slope: (2 - -3) ÷ (-4 - -8) = 5 ÷ 4 = 5/4

Point slope form: y - y₁ = m (x - x₁)

       Equation: y - 2 = 5/4 (x - -4)

                        distribute the 5/4

                        y - 2 = 5/4 (x) + 5

                        add 2 to both sides

                        y = 5/4 (x) + 7

I hope this helps!

The number of miles did he hike altogether is 4 miles.

Given that,

Based on the above information, the calculation is as follows:

= 2.5 miles + 1.5 miles

= 4 miles

Therefore we can conclude that the number of miles did he hike altogether is 4 miles.

Answer:

the first answer is 10 and the second is 40

Step-by-step explanation:

there actually asking how many meters would make 1 centimeter

On the ruler 1 whole centimeter is 10 meter. (The longer line behind the number is the 10th meter )

Dividing fractions

1 ÷ 1/10

Steps

Change the whole number which is 1 into a fraction.

1/1 ÷1/10

Flip the second fraction in the equation.

1/1 ÷ 10/1

Then change the division sign to a multiplication sign. So were multiply instead.

1/1 × 10/1

Multiply the fractions and your answer should be 10/1 .

This fraction is also changed to a whole number.

10/1 = 10

1. 14 loaves are needed for 63 customers

2.  90 loaves

3. 4.5 loaf

Step by Step:

9/2= 4.5

4.5x4= 18

27/4.5=6

14x4.5=63

I multiplied and divided everything by 4.5 so one loaf of bread is 4.5.

(Correct me if I'm wrong)

I hope this helped! :)

Answer:

Step-by-step explanation:

1) Number of jeans = x

Number of blouses = y

Total items = 6

x +  y = 6 -------------------(I)

       y = 6 - x

Cost of 'x' jeans =  300 *x = 300x

Cost of y blouses = 100 * y = 100y

Total amount  = Php. 1000

300x + 100y = 1000 ------------(II)

2) Substitute y = 6 - x in equation (II)

         300x + 100(6-x) = 1000

300x + 6*100 - x *100 = 1000

 300x + 600 - 100x   = 1000

                200x + 600=1000

                          200x = 1000 - 600

                          200x = 400

                               x = 400/200

x = 2

Plugin x = 2 in equation (I)

2 + y = 6

     y = 6 - 2

     y = 4

Number of jeans = 2

Number of blouses = 4

3) This equations have only one solution. So, they are consistent and independent

Answer:

(0,5)

(2,1)

(4,-3)

Step-by-step explanation:

so all you have to do is plug in the x value and if the y value comes out to be whatever is matches up with then it is a solution to the equation for example if you plug in 0 to y=-2x+5 then you get 5 and below it says that when x=0 then y=5 which is true so that would be an answer now if you plug in 2 then you get 1 and it says that when x=2 y=9 which is not correct. sorry if this doesnt make sense its so hard to explain virtually

Answer:

0° and 18°

Step-by-step explanation:

3tan²β - tanβ = 0

tanβ(3tanβ - 1) = 0

tan β = 0 ⇒ [tex]\beta _{1}[/tex] = 0°

3tan β - 1 = 0 ⇒ tan β = [tex]\frac{1}{3}[/tex] ⇒ [tex]\beta _{2}[/tex] = arctan ( [tex]\frac{1}{3}[/tex] ) ≈ 18°

Answer:

[tex]3 \tan {}^{2} \theta - \tan\theta= 0 \\ \tan\theta(3 \tan \theta- 1) = 0✓\\\\\tan\theta = 0 \\\boxed{\theta = 0°} ✓\\\\ 3 \tan\theta - 1 = 0 \\3 \tan \theta = 1 \\ \tan \theta = \frac{1}{3} \\ \theta = { \tan }^{ - 1} ( \frac{1}{3} ) \\\boxed{\theta = 18.4°}✓[/tex]
