There are 8 jars of jellyfish jelly for $15.68. Write a proportion that gives the cost (c) if you buy 6 jars of jellyfish jelly.
Answer:
The proportion that gives the cost (c) if you buy 6 jars of jellyfish jelly =
Cost(c)= 1/8($15.68 × 6)
The cost (c) if you buy 6 jars of jellyfish jelly is $11.76
Step-by-step explanation:
There are 8 jars of jellyfish jelly for $15.68. Write a proportion that gives the cost (c) if you buy 6 jars of jellyfish jelly.
The proportion is given as:
Number of jars of Jellyfish/Cost of the Number of jar of Jellyfish
Hence:
8/$15.68 = 6/c
We Cross Multiply
8 × c = $15.68 × 6
c = $15.68 × 6/8
c = $11.76
Therefore,
The proportion that gives the cost (c) if you buy 6 jars of jellyfish jelly =
Cost(c) = 1/8($15.68 × 6)
The cost (c) if you buy 6 jars of jellyfish jelly is $11.76

$420 is divided between A, B and C. B receives $20 less than A, and C receives half as much as A and B together. how much does each receive?
Also could you explain the answer?
Answer:
A = $150
B = $130
C = $140
Step-by-step explanation:
Let the amount received by a be $x
b receives $20 less than a;
we have that;
b = x - 20
c receives half of Sum A and B
c = (x + x-20)/2
c = (2x-20)/2
c = x - 10
Add all and it gives 420
x - 10 + x -20 + x = 420
3x -30 = 420
3x = 420 + 30
3x = 450
x = 450/3
x =$150
a = 150
b = x - 20; 150 - 20 = 130
c = x-10
c = 150-10
c = $140
Sweets are sold loose or pre packed in 120 G bags. The 120 G bags are 1.49 pounds each By calculating the price per gram determine which is better value show ur working out
Complete question :
Sweets are sold loose, or pre-packed in 120g bags.The 120g bags are £1.49 each.The loose sweets are £0.89 for 100g.
By calculating the price per gram, determine which is better value.
Answer:
100 g bag
Step-by-step explanation:
For the 120g bag:
Price per gram :
Price / Numbe of gram
1.49 / 120 = 0.0124 gram per bag
For the 100 g bag :
0.89 / 100
= $0.0089per gram
Since $0.0089 is < $0.0124
Then the 100g bag is of better value

Mateo is studying a human hair with a diameter of 6.5 x 10-4 inches and a horse hair with a diameter of 1.3 x 10-3 inches. Which statement is true?
Answer:
The diameter of horse hair is twice as thick as the diameter of the human hair.
Step-by-step explanation:
The diameter of a human hair = [tex]6.5\times 10^{-4}\ \inches[/tex]
The diameter of a horse hair = [tex]1.3\times 10^{-3}\ \inches[/tex]
Dividing the diameter of a horse hair to the diameter of a human hair as follows :
[tex]\dfrac{\text{Diameter of human hair}}{\text{Diameter of horse hair}}=\dfrac{6.5\times 10^{-4}}{1.3\times 10^{-3}}\\\\\dfrac{\text{Diameter of human hair}}{\text{Diameter of horse hair}}=\dfrac{1}{2}\\\\\text{Diameter of horse hair}=2\times \text{Diameter of human hair}[/tex]
So, the diameter of horse hair is twice as thick as the diameter of the human hair.
Answer:
The horse hair is 2 times as thick as the human hair.

Answer:
y = 3/2 x + 7
Step-by-step explanation:
Line intercept form =
Y = mx + b
m is the slope (rise over run) and b is the y intercept.
So what you want to first is get y by itself.
9x-6y = -42
-6y = -42 - 9x
y = 9/6 x + 7
y = 3/2 x + 7

In ΔHIJ, i = 6.6 inches, j = 6.4 inches and ∠H=62°. Find the length of h, to the nearest 10th of an inch.
Law of cosine helps us to know the third side of a triangle. The length of the third side of the ΔHIJ, h is 6.698 inches.
What is the Law of Cosine?The law of cosine helps us to know the third side of a triangle when two sides of the triangle are already known the angle opposite to the third side is given. It is given by the formula,
[tex]c =\sqrt{a^2 + b^2 -2ab\cdot Cos\theta}[/tex]
where
c is the third side of the triangle
a and b are the other two sides of the triangle,
and θ is the angle opposite to the third side, therefore, opposite to side c.
As it is given that the length of the first two sides of the triangle is i=6.6inches and j=6.4 inches, while the measure of the ∠H=62°. Therefore,
the length of the third side with the help of cosine rule can be written as,
[tex]h =\sqrt{i^2 + j^2 -2ij\cdot Cos(\angle H)}\\\\h =\sqrt{(6.6)^2 + (6.4)^2 -(2 \times 6.6 \times 6.4)\cdot Cos(62^o)}\\\\h = 6.6976 \approx 6.698[/tex]
Hence, the length of the third side of the ΔHIJ, h is 6.698 inches.

Answer:
x=56
Step-by-step explanation:
Alternate exterior angles are congruent if the lines crossed by the transversal are parallel (which they are).
Answer:
56
Step-by-step explanation:
It would also be 56 degrees because if both 360 degree angles are parallel to each other and if each of the 360 degree angles had two top and bottom 180 degree angles and if 56 was subtracted to 180 you would get 124 and when you plus that with 56, you get 180 so if that is true for all 4 180 degree angles in this problem, then X would equal 56 no doubt.
