Answer:

Anna gets £45, Bertie gets £36 and Carl gets £54

Step-by-step explanation:

→ Add the ratios together

5 + 4 + 6 = 15

→ Divide the amount by the total of ratios

135 ÷ 15 = 9

→ Multiply 9 by each part of the ratio

Anna = 5 × 9 = £45

Bertie = 4 × 9 = £36

Carl = 6 × 9 = £54

Answer:

For the new set of marks, the median is of 55

Step-by-step explanation:

The median is the halfway point of a dataset, that is, the value that separates the lower 50% of the data set from the upper 50%.

In a data set, if we subtract or add all marks by x, the median will be subtracted or added by x.

In this question, we have that:

Median 65

From all marks, 10 is subtracted.

So, for the new set of marks, the median is of 65 - 10 = 55

Answer:

Juan went to a wholesale store to buy eggs for his restaurant. The wholesale store only sells eggs by the dozen, at $3.29 per dozen

What is the greatest number of individual eggs he can buy for $50.00?

Step-by-step explanation:

Cost of 12 eggs are $3.29

Cost of 1 egg is ($3.29/12)=$0.27

Juan has $50.00

Therefore, he could buy ($50/$0.27)=182 eggs

Answer:  13

Step-by-step explanation:

Answer:

y = 5x - 14

slope intercept form is y = mx + b

m = slope

after substituting 5 in for m you end up with y = 5x + b

you substitute (2, -4) for x and y

-4 = 5(2) + b

next step is to solve for b.

Answer:

isosceles and right

I'm not sure

Answer:

Isosceles and right

Step-by-step explanation:

The square in the corner indicates the triangle is a right triangle. The two lines represent congruence. Since the triangle has two equal lines, it is an isosceles triangle. Overall, the triangle is isosceles and right.

Answer:

[tex]y = \frac{2}{3} x - 2 \\ [/tex]

Answer: b₁ = 7 and b₂ = 14.

Triangle: base=21 cm, height=6cm

Trapezoid: height=6 cm, b1=?, b2=?

Triangle -> A=bh/2 -> A=63 (b is base  and h is height)

Trapezoid ->  A=[(b₁+b₂)/2)]h (b₁ and b₂ are bases and h is height)

Since they have the same area, the formula will be:

63=[(b₁+2(b₁))/2)]h

x=7

Answer:

b₁ = 7 cm, b₂ = 14 cm

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

Here b = 21 and h = 6, then

A = 0.5 × 21 × 6 = 63 cm²

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

Here A = 63 ( same as triangle ), h = 6 and b₂ = 2b₁ , then

0.5 × 6 × (b₁ + 2b₁ ) = 63

3 × 3b₁ = 63

9b₁ = 63 ( divide both sides by 9 )

b₁ = 7

and b₂ = 2 × 7 = 14

The bases of the trapezoid are 7 cm and 14 cm

Answer:

<AFB

Step-by-step explanation:

The angle that is a vertical angle with <EFD would be the angle that is vertically opposite and equal to <EFD.

Taking a look at the diagram, yiu would observe that <AFB is vertically opposite to <EFD. Therefore, <AFB is a vertical angle with <EFD.

Answer:

The answer is D

Step-by-step explanation:

I just did the test

Answer: (D) He should have multiplied the choices, instead of adding them.

Step-by-step explanation: I took the QUIZ and it was correct.

Since he added it doesn't show ALL the possible combinations, so he should have multiplied.

Hope I helped :D

Answer:

can you take a picture of the scatter plot or show the data for it? Then I can help you.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Now, in order for it to be a proportion, both the number and the denominator must turn to the other number by the same method. I'll clarify when we do the steps.

So, the first one is 4/10 and 10/25

The first thing that you would do is divide 10 by 4, and then 25/10

When you do that, it turns out that they both equal 2.5. This means that both the number and denominator go to the new number with the same method, multiplying by 2.5

So, the answer would be A

Answer:

31.2

Step-by-step explanation:

2.60 times 4 is 10.4.

4 times 3 is 12

10.4 times 3 is 31.2

Answer:

Hello!

A dozen muffins would cost $7.80

----------------------------------------------------------------------------------------------------------------

So if you took for muffins the price would be $2.60 But thats not a dozen

Dozen = 12 muffins

So for 12 muffins you  would have to take 4 muffins times 3 (4x3=12)

So to find the price you need to do $2.60 x 3 and you would get $7.80

Hope I helped!
