A muffin recipe calls for 2 eggs to make 12 muffins.
If you want to make 36 muffins, what should you do?
Answers
2 eggs/ 12 muffins = x eggs/ 36 muffins
They will have to be proportional
2/12 = x/36
12 * 3 = 36
2 * 3 = 6 eggs
You will need 6 eggs
Answer:
6 eggs
Step-by-step explanation:
since recipe states that to make 12 muffins you need 2 muffins
2. = 12
represent the unknown with x
2. = 12
x. = 36
Then you'll cross multiply
36 × 2 = 72
12x = 72
x = 72 ÷ 12
x = 6

A car travels 20miles be in 1/2 hour at constant speed is traveling at the same speed as a car that travels 30 miles in 3/4 hour at a constant speed.explain or show why
Answers
Answer:
It is true that both cars are traveling at the same speed.
Step-by-step explanation:
Given that car A travels 20 miles over half an hour, we know that this car is traveling at a speed of 40 miles per hour.
Car B travels 30 miles in 3/4 of an hour, let us set up a proportion to solve whether or not Car B is traveling at the same rate as Car A
30 miles / (3/4 hour) = x miles / 1 hour Cross multiply
30 = (3/4) x Divide both sides by (3/4)
40 = x
Therefore, both Car A and Car B are traveling at the same rate.

Which of the following can be the sides of a right angled triangle?
(i) 1.5 cm, 2 cm, 3 cm (ii) 6 cm, 1.1 cm, 6.1 cm
Answers
Answer:
(ii) 6 cm, 1.1 cm, 6.1 cm
Step-by-step explanation:
Knowing that all right triangles obey the Pythagorean Theorem, we can test both sets of numbers. The longest of the 3, the hypotenuse, is substituted to the c value of the equation a^2 + b^2 = c^2. If the equation is still true after substituting and simplifying both sides, that combination of triangle lengths is the correct answer. In this case, 6^2 + 1.1^2 and 6.1^2 are both equal to 37.21, so the second set is correct.

What is the measure of angle L
Answers
Answer:
∠L=23°
Step-by-step explanation:
(6x-5)+(x+9)=(9x-24) (ext angle of triangle)
6x-5+x+9=9x-24
7x+4=9x-24
7x-9x=-24-4
-2x=-28
2x=28
x=28÷2
=14
Hence, ∠L = (x+9)°
= (14+9)°
= 23°
