Answer:
Step-by-step explanation:
x, 30 - x add to 30. The other condition says
x (30 - x) = 176. Multiply it out.
30x - x^2 = 176, so
x^2 - 30x = -176, complete square by adding 15^2 to both sides
(x - 15)^2 = 225 - 176 = 49, take square root
x - 15 = 7, so one number is:
x = 22 and the other is 30 - x = 8.
The sum of 8 times b and twice g is equal to 32
A circular pool has a radius of 10 feet. What is the area of the pool? Use 3.14 for it. The area of the pool is about ft?
Answer:
314ft^2
Step-by-step explanation:
The area of a circle is found using this equation:
A=3.14r^2
r = radius
so if we know the radius is 10ft, we can put that into the equation and it will read:
A=3.14(10)^2
^2 means squared, for clarification.
Using PEMDAS we know to do exponents first
A=3.14(100)
Now multiply
A=314
and don't forget to add your units and square!
A=314ft^2

Using the word HIPPOPOTAMUS, match the items in the left column to the items in the right column
1 the ratio of P's to O's
2. the ratio of O's to other letters
3. the ratio of letters to P's
4. the ratio of vowels to consonants
5. the ratio of total letters to consonants
The right column has 3:2,12:7,1:5,5:7,4:1
Answer:
(see below)
Step-by-step explanation:
Ratios are simple: they describe the amount of something compared to another amount.
Ratios are [number] : [number]. Use this format for your answers:
For 1, finding the ratio of P's to O's means to count P's, then O's.
HIPPOPOTAMUS
There are 3 P's and 2 O's, so 3:2.
For 2—ratio of O's to the other letters, do the same thing:
HIPPOPOTAMUS
There are 2 O's and 12 total letters, so 2:12. However, we can simplify that to 1:6.
For 3, the ratio of letters to P's:
There are 3 P's and 12 total letters, so 12:3. We can simplify it to 4:1.
For 4, the ratio of vowels to consonants:
The vowels are a, e, i, o, u. The consonants are all the other ones.
So, in:
HIPPOPOTAMUS
There are 5 vowels and 7 consonants, so 5:7.
For 5, the ratio of total letters to consonants,
there are 12 total letters and 7 consonants, so 12:7.

An aquarium holds 11.94 cubic feet of water, and 2.6 feet long and 1.4 feet wide. What is its depth? Round your answer to the nearest whole number.
Answer:
The depth of the aquarium is 3 feet.
Step-by-step explanation:
From the formula for the volume of a bar we find that [tex]V=whl[/tex], where [tex]w[/tex] is the width, [tex]h[/tex] is the height (depth), and [tex]l[/tex] is the length of the bar (which in this case is the aquarium). So [tex]h=\frac{V}{wl}[/tex] and by substituting [tex]V=11.94[/tex], [tex]w=1.4[/tex] and [tex]l=2.6[/tex] we can see that [tex]h=\frac{V}{wl} = \frac{11.94}{2.6 \cdot 1.4} = 3.2802... \approx 3[/tex] feet (rounding to the nearest whole number).
So the depth of the aquarium is 3 feet.
The difference of two numbers is 15. Five times the smaller number is the same as 9 less than twice the larger number. Find the numbers.
Answer:
Step-by-step explanation:
"The difference of two numbers is 15."
x-y = 15
x>y
"Five times the smaller number is the same as 9 less than twice the larger number."
5y = 2x-9
y = x-15
substitution
5(x-15) = 2x-9
5x-75 = 2x-9
3x = 66
x = 22
y = x-15 = 7

Which equation represents the line that passes through the point (3,-1) and is perpendicular to the graph of x+4y=10
Answer:
Step-by-step explanation: The given equation is in standard form, so it must be converted to slope-intercept form: y = mx + b to discover the slope is –2/3. To be perpendicular the new slope must be 3/2 (opposite reciprocal of the old slope).
4x - y = 13 represents the line that passes through the point (3,-1) and is perpendicular to the graph of x+4y=10.
What is perpendicular equation?A perpendicular line is a straight line through a point. It makes an angle of 90 degrees with a particular point through which the line passes.
Given
x + 4y = 10
∴ 4y = -x + 10
∴ y = [tex]\frac{-1}{4} x + \frac{5}{2}[/tex]
so y = 4x + b pass through the point (3, -1)
⇒ -1 = 4 × 3 + b
⇒ -1 = 12 + b
⇒ b = -1 - 12
⇒ b = -13
∴ y = 4x -13
4x - y = 13
Hence, 4x - y = 13 represents the line that passes through the point (3,-1) and is perpendicular to the graph of x+4y=10.
