The sum of twice a number and 4 times another number is 4. The first number decreased by the
econd number is 5. Find the numbers.
Answer:
4 and -1
Step-by-step explanation:
Let :
First number = xSecond number = yEquations formed :
2x + 4y = 4 ⇒ x + 2y = 2x - y = 5Subtract : Equation 1 - Equation 2
x + 2y - x + y = 2 - 53y = -3y = -1x - (-1) = 5x + 1 = 5x = 4The numbers are : 4 and -1

find the distance between (5,5) and (8,1)
Answer:
5
Step-by-step explanation:
Imagine a triangle with two of the corner points being the points (5,5) and (8,1)
The length and width would be 3 and 4 to find the hypotenuse (distance) do
3^2+4^2=x^2
9+16=x^2
25=x^2
x=5
[tex]here \: is \: your \: answer...[/tex]
Step-by-step explanation:
Let (x1,y1) = (5,5) and (x2,y2) = (8,1)
By using distance formula,
[tex]d \: = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } [/tex]
[tex]d = \sqrt{ {(8 - 5)}^{2} + {(1 - 5)}^{2} } [/tex]
[tex]d = \sqrt{ {(3)}^{2} + {( - 4)}^{2} } [/tex]
[tex]d = \sqrt{9 + 16} [/tex]
[tex]d = \sqrt{25} [/tex]
[tex]d = 5 \: units[/tex]
Therefore, the distance between (5,5) and (8,1) is 5 units
A long distance race begins with 28 runners from Team A and 28 runners from Team B. 4 runners from Team A and 12 runners from Team B do not finish the race. What percentage of the runners who finish the race are from Team B?
The percentage of the runner from team B that finishes the race is 21.4%
How to find the percentage that finish the race from team B?
Team A and Team ran a race. Team A had 28 runners and Team B also had 28 runners.
4 runners from team A finishes the race while 12 runners from team B finishes the race.
Therefore, the percentage from team B that finishes the race can be calculated as follows.
percentage from team B that finishes = 12 / 56 × 100
percentage from team B that finishes = 1200 / 56
percentage from team B that finishes = 21.4285714286
percentage from team B that finishes = 21.4%

In a right triangle, a and b are the lengths of the legs and c is the length of the hypotenuse. What is C?
Answer:
C is 6.3
Step-by-step explanation:
We can apply the pythagorean theorum to find C.
A is 2, B is 6
A^2 + B^2 = C^2
2^2 + 6^2 = C^2
C^2 = 40
C = 6.32455532

a) What percentage of the ingredients are salt and flour?
Answer:
Ingredient Percentage=Ingredient Weight/Total Flour x 100%
Step-by-step explanation:
For example, if a formula calls for 60 pounds of water and 100 pounds of flour, the baker's percent would be 60% water. If there are two types of flour being used, the combination of the weight of both flours will be 100%.
The area of the circle above is 200.96 units? What is the circumference of the circle? Use a = 3.14.

B. 25.12 units
C. 100.48 units
D. 66.99 units
Answer:
50.24
Step-by-step explanation:
Area = 200.96
Let's find the raidus from the area formula.
200.96 = π · r^2
Divide both sides by π !
64 = r^2
square root both sides
r = 8.
Now since we know the raidus we can find the circumferewnce.

Mieko bought 2 gallons of paint. She used 1/4 of the paint in her bedroom, 3 quarts in the hallway, and the rest of the paint in the living room. How many quarts of paint did she use in the living room?
A: 3 Quarts
B. 8 Quarts
C. 10 Quarts
D. 12 Quarts
=======================================================
Explanation:
1 gallon = 4 quarts
2 gallons = 8 quarts
1/4 of 8 quarts = 2 quarts
She used 2 quarts for her bedroom and 3 for the hallway. Therefore, she used 2+3 = 5 quarts total.
That leaves 8 - 5 = 3 quarts for the living room.
Answer:
A: 3 Quarts
Step-by-step explanation:
1 gallon = 4 quarts
1/4 of 2 gallons = 1/4 × 2
= 1/2 gallon
⇒ 1/2 gallon = 2 quarts
Therefore, Mieko used 2 quarts of paint to paint her bedroom.
If she used 3 quarts to paint the hallway, then
⇒ total number of quarts used = 2 + 3 = 5 quarts
As she bought a total of 2 gallons of paint:
⇒ 2 gallons = 2 × 4 = 8 quarts
Therefore the remaining unused paint (to paint the living room) is:
⇒ total paint - used paid = 8 quarts - 5 quarts
= 3 quarts

Answer:
x=10
y=[tex]10\sqrt{3}[/tex]
Step-by-step explanation:
Since there is a 30 degree angle, it is a special right triangle, 30 60 90 triangle. The shorter leg represents "a," the longer leg represents "a√3", and the hypotenuse represents 2a.
The triangle has a hypotenuse of 20 and we are trying to find x and y. x=10 because x is the opposite side of 30 degrees and x is half of the hypotenuse. y=[tex]10\sqrt{3}[/tex] because we already know the x value and y is opposite of 60 degrees. As mentioned before, the longer leg represents a√3.

For F(x)=3x+4 and g(x)= x^2-3x, find g(f(x)).
Answer:
g(f(x)) = 9x² + 15x + 4
Step-by-step explanation:
Given :
⇒ f(x) = 3x + 4
⇒ g(x) = x² - 3x
=============================================================
Solving :
⇒ g(f(x))
⇒ g(3x + 4) = (3x + 4)² - 3(3x + 4)
⇒ g(3x + 4) = (3x)² + 2(3x)(4) + (4)² - 9x - 12
⇒ g(3x + 4) = 9x² + 24x + 16 - 9x - 12
⇒ g(f(x)) = 9x² + 15x + 4

price. Tiana pays a total of $13.20 for the cans of soup.
Which equation can you use to find the amount, f, each can of soup costs at full price?
0.55(f - 12) = 13.20
12(f - 0.55) = 13.20
0.55f - 12 = 13.20
12f - 0.55 = 13.20
How much does each can of soup cost at full price?
$
Answer:
1.65
Step-by-step explanation:
equation will be 12(f−0.55)=13.20
12f−6.6=13.20
12f = 19.8
f = 19.8/12 = 1.65

You are designing a large rectangular fish tank for your tropical fish. The length will be 1 yard 3 inches, the width will be 1.5 feet, and the height will be 20 inches.
Part A
Find the volume of the fish tank in cubic inches.
The volume is
cubic inches.
Part B
Your math teacher tells you that your fish tank will have a capacity of about 976 cups. You have a total of 30 tropical fish. For them to flourish in a fish tank, there needs to be an average of 2 gallons of water for each fish.
Convert 976 cups to gallons.
976 cups equals
gallons.
Answer:
A. 14040 cubic inches
B. 61 gallons
Step-by-step explanation:
The volume of a cuboid is given by the formula ...
V = LWH
__
A.One yard is 36 inches, so 1 yard 3 inches is 36 +3 = 39 inches.
One foot is 12 inches, so 1.5 ft = 1.5×12 = 18 inches.
The volume of the fish tank is ...
V = (39 in)(18 in)(20 in) = 14,040 in³
The volume is 14,040 cubic inches.
__
B.One gallon is 16 cups, so 976 cups is 976/16 = 61 gallons.
976 cups equals 61 gallons.
_____
Additional comment
One gallon is 231 cubic inches, so the volume of the tank is actually about 972 cups, or 60.8 gallons.
