Answer:
16.5 : 38.5
Step-by-step explanation:
sum the parts of the ratio, 3 + 7 = 10 parts
Divide the amount by 10 to find the value of one part of the ratio.
55 ÷ 10 = 5.5 ← value of 1 part of the ratio, then
3 parts = 3 × 5.5 = 16.5
7 parts = 7 × 5.5 = 38.5
55 in the ratio 3 : 7 is 16.5 : 38.5

bag of Hot Fries for $1.99 and 6 packs of gum. He
gets $11.77 in change. What is the price of one
pack of gum?
Answer:
First we need to subtract the hot fries. 20 - 1.99 = 18.01
he gets 11.77 so lets subtract it is 6.94 left so now divide by 6 is 1.5666666 or 1.6 per pack

if five slices of pizza costs 5.50 how much would two slices cost? ten slices? half a slice?
Answer:
The first thing we must do for this case is to define variables.
We have then:
x: number of slices
y: total cost
We write the linear function that relates the variables.
We have then:
Then, we evaluate the number of slices to find the total cost.
-two slices cost:
We substitute x = 2 in the given equation:
Answer:
two slices = 2.2 $
-ten slices cost:
We substitute x = 10 in the given equation:
Answer:
ten slices = 11 $
-half a slice cost:
We substitute x = 1/2 in the given equation:
Answer:
half a slice = 0.55 $

In right triangle ABC, AC = 4 and BC = 5. A new triangle DEC is formed by connecting the midpoints of AC and BC. What is the area of triangle ABC? *
You can use the Pythagoras theorem to find the height of the triangle given and then by the height and the base of the triangle, you can find its area.
The area of the triangle ABC is 6 square units.
Right angled triangle:A right angled triangle is a triangle having one of its angle with measure of 90 degrees.
The slant side of that triangle is called Hypotenuse and it is the longest side in that triangle.
The Pythagoras theorem:If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
[tex]|AC|^2 = |AB|^2 + |BC|2[/tex]
How to find the area of given right angled triangle ABC?Refer to the diagram attached below.
Since we have right angle at angle A, and we have
|AC| = 4 units, |BC| = 5 units, let |AB| = [tex]x[/tex] units, then
[tex]|AC|^2 + |AB|^2 = |CB|^2\\4^2 + x^2 =5^2\\x ^2 = 25-16\\x = \sqrt{9} = 3 \text{\:(Positive root since x is length which is non negative quantity)}[/tex]
Area of a triangle is half of its base times height.
Since the line AC s perpendicular to AB, thus we can take base as AB and height as AC, then we have:
[tex]Area = \dfrac{1}{2} \times |AC| \times |AB| = \dfrac{1}{2} \times 4 \times 3 = 6 \: \rm unit^2[/tex]
Thus,
The area of the triangle ABC is 6 square units.

Kiara has a box that is 20 centimeters long, 5 centimeters wide, and 10 centimeters deep. She wants to fill the box with other packages that
are 5 centimeters long, 1 centimeter wide, and 4 centimeters deep.
What is the greatest number of packages that she can put in the box without it overflowing?
Answer:
50 packages
Step-by-step explanation:
Area of the box: A= (l)(w)(h)
=(20)(5)(10)
=1000cm^3
Area of the package: A= (5)(1)(4)
=20cm^3
1000/20=50 packages
50 number of packages that she can put in the box without it overflowing
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given that Kiara has a box that is 20 centimeters long, 5 centimeters wide, and 10 centimeters deep.
Length=20
Width=5
Height=10
Area of cube=Length×width×height
=20×5×10
=1000 cm³
The other packages is 5 centimeters long, 1 centimeter wide, and 4 centimeters deep.
Area=5×1×4
=20 cm³
We need to find the greatest number of packages that she can put in the box without it overflowing
To find this we have to divide 1000 by 20
1000/20=50
Hence, 50 number of packages that she can put in the box without it overflowing

Gina has 5 2/8 feet of silver ribbon and 3 6/8 of gold ribbon. How much more silver ribbon does Gina have than gold ribbon.
Answer: we are simply to subtract the length of the gold ribbon which is 2 4/6 ft from the length of the silver ribbon, 5 2/6 feet. Mathematically,
5 2/6 feet - 2 4/6 feet = 8/3 feet
Therefore, Gina has 8/3 feet more of the silver ribbon than the golden ribbon.

Carter used 1 1/3 gallons of paint to paint 2/5 of a wall. How many gallons will it take to paint the whole wall? Show your reasoning with a diagram.
Answer:
3 1/3 gallons
Step-by-step explanation:
It is more helpful to think of the wall as 5 sections. if two sections used 4/3, by logic one section uses 2/3 (because 4/3 ÷ 2 = 2/3). since there are 5 sections, 2/3 × 5 you get 10/3. turn it into a mixed fraction and you get 3 1/3.

Answer:
D) (2, 14)
Step-by-step explanation:
substitute each coordinates into the inequality:
(0, 0)
y > 5x
0 > 5*0
0 > 0
this is false, 0 = 0.
(3, 12)
y > 5x
12 > 5 * 3
12 > 15
this is false, 12 < 15
(-2, -10)
y > 5x
-10 > 5 * -2
-10 > -10
this is false, -10 = -10
(2, 14)
y > 5x
14 > 5 * 2
14 > 10
this is true, 14 > 10
Answer:
It would be (0,0)
Step-by-step explanation:

Find the y-intercept.
Y-intercept: value of y when x = 0
Substitute 0 for x and solve for y.
y > - 5(0) y > - 5x.

Answer:
no
Step-by-step explanation:
x = 2
y = 0
substitute x with 2 and y with 0
0 = 6(2)
0 = 12
this is not true, so (2,0) is not a solution
