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
1) A bread recipe contains 60g of butter, 40g of salt and 100g of flour.
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%.
What is the distance between parallel lines y=x+3 and y=x+1, rounded to the nearest hundredth?\
The distance between two parallel lines y=x+3 and y=x+1 will be equal to
[tex]d=\dfrac{1}{\sqrt{2}}[/tex]
What is parallel lines?The lines which do not intersect to each other and only intersect at infinity are called parallel lines.
Here we have two lines:-
y=x+3
y=x+1
The formula for the distance between two parallel lines is given by:-
[tex]d=\dfrac{|C_1-C_2|}{\sqrt{a^2+b^2}}[/tex]
We have C1=3 C2=1 a=1 b=1 by putting the value in the formula we will get:-
[tex]d=\dfrac{3-2}{\sqrt{1^2+1^2}}=\dfrac{1}{\sqrt{2}}[/tex]
Hence distance between two parallel lines y=x+3 and y=x+1 will be equal to [tex]d=\dfrac{1}{\sqrt{2}}[/tex]

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.

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.

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

The width of a rectangle is 4 cm and its perimeter is 26 cm. What is the perimeter of a square has the same area as the rectangle
Answer:
length = 9 cm
Step-by-step explanation:
perimeter = p =26 cm
width = w= 4 cm
perimeter of a rectangle= 2*w+2*L
L= length
so we have:
26 = 2*(4) +2*L
26= 8 +2L
26-8 = 2L
18 = 2L
L= 18/2
L =9 cm = length

According to the given question
Cost price for five students for taking admission to the museum and lunch is 36.25 and 31.50 respectively.
cost price for one student for taking admission in museum = [tex]\frac{36.25}{5} = $7.25[/tex]
cost price for one student lunch = [tex]\frac{31.50}{5} = 6.3[/tex]
Therefore,
The total cost for each student for the admission and lunch = 7.25+6.3 =
$13.55
And, the total cost for 30 students for admission and lunch = 30×$13.55 =$406.5
Hence, the total cost for admission to museum and lunch for each student is $13.55 and for 30 students is $406.6.

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

a) see below
b) 29.7% (1 d.p.)
c) 64.6% (1 d.p.)

Calculations to fill the table:
Total enrolled = 102 + 82 = 184Female not enrolled = 158 - 102 = 56Male total = 278 - 158 = 120Male not enrolled = 120 - 82 = 38Total not enrolled = 56 + 38 = 94Therefore:

Part (b)
[tex]\sf Percentage=\left(\dfrac{Value}{Total\:value}\right) \times 100[/tex]
Number of students who are male and enrolled = 82
Total number of students = 278
