Determine whether each of the following problems
will have a rational or an irrational answer. Your
answer should be either the word "rational or
"irrational."
18 + 1
Answer:
irrational
Step-by-step explanation:
pi itself is irrational, so adding something to it makes no difference
Answer: Irrational
Step-by-step explanation: The sum of two rational numbers is
✔ always rational.
The sum of a rational number and an irrational number is
✔ never rational.
The product of a rational number and an irrational number is
✔ always irrational.
The product of two rational numbers is
✔ never irrational.
Determine whether each of the following problems will have a rational or an irrational answer. Your answer should be either the word “rational” or “irrational.”
18+pi = irrational
A repeating decimal + A fraction =rational
3/13 x sqrt 52 =irrational
A lamp shade is in form of a frustum of a cone , its upper and lower diameter are 10cm and 20cm respectively , its height is 12cm . Calculate the volume of the frustum
Answer:
V = 8796.45 [tex]cm^3[/tex]
Step-by-step explanation:
Given data :
A lamp shade is in the form of a frustum of a cone.
The upper diameter of the cone, r = 10 cm
The lower diameter of the cone, R = 20 cm
The height of the frustum, h = 12 cm
Therefore, the volume of the frustum of cone is given by :
[tex]V = \frac{1}{3} \pi H ( R^2 + Rr+r^2)[/tex]
Putting the values, we get
[tex]V = \frac{1}{3} \pi \times 12 [( 20)^2 + (20)(10)+(10)^2][/tex]
[tex]$V=4 \pi[400 + 200+100]$[/tex]
[tex]$V=4 \pi[700]$[/tex]
V = 8796.45 [tex]cm^3[/tex]
Thus the volume of the frustum of cone is V = 8796.45 [tex]cm^3[/tex]
Put these numbers in order from least to greatest.

2x + z = 46
3z= 18
2y + z= 40
Answer:
x=20, y=17, and z=6 or (20,17,6)
Step-by-step explanation:
Hi there!
We're given the system of equations:
2x+z=46
3z=18
2y+z=40
and we need to solve for x, y, and z
first, let's find the value of z, as we have z by itself (no other variables) in 3z=18
divide both sides by z
z=6
the value of z is found :)
now we can use z=6 to find the value of the other variables; for example, plug z as 6 into 2x+z=46 to solve for x
2x+6=46
subtract 6 from both sides
2x=40
divide by 2
x=20
Finally, let's find y
once again, we can substitute z as 6 in the equation 2y+z=40 to find y
2y+6=40
subtract 6 from both sides
2y=34
divide by 2
y=17
so the answer is: x=20, y=17, and z=6; if you need it in a point it's (20,17,6)
Hope this helps! :)

Harriet and Maya share £300 in the ratio of 7:5. Wirk out how much money harriet gets
Answer:
$175
Step-by-step explanation:
you need to specify if harriet got the 7 portion or the 5 portion. I'll answer as if she got the 7 portion.
They split it into 12 portions because the ratio is 7:5 and 7+5=12. So do $300/12=25
Assuming Maya got the 5 portion, do $25 x 5 = $125, so Maya got $125.
Assuming Harriet got the 7 portion, do $25 x 7 = $175, so Harriet got $175.

josh desposited $1,500 into an account that earns 6% simple interest every year. how much money would be in his account after 20 years ?
Answer:
Step-by-step explanation: example:
Problem: You deposit some money into a bank account paying 2% simple interest per 6 months. You received $15 in interest after 9 months. How much the deposit (principal) was?
Result: The principal was $500.
STEP 1: Convert interest rate of 2% per 6 months into rate per year.
STEP 2: Convert 9 months
STEP 3: Find principal by using the formula , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
In this example I = $15, i = 4% and t = 0.75 years, so

Answer:
The car price decreased by $2,268.
The price of the car now is $33,732.
Step-by-step explanation:
Multiply 0.063 (6.3% in decimal form) by $36,000 to get $2,268, which is how much the price decreased.
Then subtract 2,268 from 36,000 to get $33,73, which is the price of the car after the decrease.
Answer:
Step-by-step explanation:
6.3 : 100 = x : 36000
x = (36000 * 6.3)/100 = $2268 (decrease in price)
Price of new model: 36000 - 2268 = $33732

[tex]y = \frac{28}{5} [/tex]
Answer:
[tex]y=5.6[/tex] or [tex]y=28/5[/tex]
Step-by-step explanation:
4/5 = y/7
⇒ Cross multiply:
4 × 7 = 5 × y
⇒ Multiply 4 × 7 & 5 × y:
[tex]28=5y[/tex]
⇒ Solve the formed equation:
[tex]28=5y[/tex]
⇒ Move all the terms containing y to the right side and the other values to the left side:
⇒ Add '-5y' to each side of the equation:
[tex]28+-5y=5y+-5y[/tex]
⇒ Combine like terms: [tex]5y+-5y=0[/tex]
[tex]28+-5y=0[/tex]
⇒ Add '-28' to each side of the equation:
[tex]28+-28+-5y=0+-28[/tex]
⇒ Combine like terms: [tex]28+-28=0[/tex]
[tex]0+-5y=0+-28[/tex]
[tex]-5y=0+-28[/tex]
⇒ Combine like terms: [tex]0+-28=-28[/tex]
[tex]-5y=-28[/tex]
⇒ Divide each side by '-5':
[tex]y=5.6[/tex] or [tex]y=28/5[/tex]
hope this helps :)

WRITE AN EQUATION THAT REPRESENTS THE LINE. (USE EXACT NUMBERS)
I WILL GIVE BRAINLIEST!!!
Answer:
y = -1/2x - 3 1/2 exact fractions
y = -0.5x - 3.5 exact decimals
Step-by-step explanation:
From the two points indicated on the graph
rise goes from -4 to -5 = -1
run goes from 1 to 3 = 2
m = slope = rise/run = -1/2
slope intercept form is
y = mx+b
to find "b" use either point
using (1, -4)
-4 = (-1/2)(1) + b
-4 = -1/2 + b
Add 1/2 to both sides
-3 1/2 = b
The equation is
y = -1/2x - 3 1/2 exact fractions
y = -0.5x - 3.5 exact decimals

the taco truck sells tacos for $3 and burritos for $4. the number of items sold on a tuesday is 125 with a total income of $430. how many tacos were sold?
Answer:
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations:
3 T + 4 B =425
T + B = 125
Where T is the number of tacos sold, and B is the number of burritos sold.
Multiplying the second equation by 3, and subtracting it to the first equation:
3 T + 4 B =425
3T + 3B = 375
___________
B =50
Replacing B in any equation:
T + B = 125
T +50 =125
T =125-50
T = 75

Which function is graphed below
Answer:
Step-by-step explanation:
Graph given for the function has three segments therefore, its a piecewise function.
For a segment lying between (2, ∞)
Slope of the line = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{2}{1}[/tex]
= 2
y-intercept of the line = -2
Therefore, equation of the line will be,
y = 2x - 2
Second segment is a straight line,
Equation of the line will be,
y = 4
Third segment is a straight line.
Slope of the line = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{1}{1}[/tex]
= 1
Equation of the line will be,
y = x + b
Since, this line passes through a point (6, 7)
7 = 6 + b
b = 1
Therefore, equation of the third segment will be,
y = x + 1
So the piecewise function will be,
f(x) = 2x - 2 For x < 2
4 For 2≤ x ≤ 5
x + 1 For x > 5

Find the volume of the composite solid below.
4 in.
4 in.
5 in.
5 in.
5 in.
Answer:
326.06 in^3
Step-by-step explanation:
Volume of the cylinder = [tex]\pi[/tex] · [tex]r^{2}[/tex] · h
Volume of the cylinder = [tex]\pi[/tex] · [tex]4^{2}[/tex] · 4
Volume of the cylinder = [tex]\pi[/tex] · 16 · 4
Volume of the cylinder = [tex]\pi[/tex] · 64
Volume of the cylinder = 201.06 in^3
Volume of the composite = length · width · height
Volume of the composite = 5 · 5 · 5
Volume of the composite = 125 in^3
201.06 + 125 = 326.06 in^3
