Which system of equations has one solution?
pls help me with this asap you dont have to give a big explanation i mostly need the answer
Answer:
because 3 spheres is inside the cylinder and they are placed close together
=> The height of the cylinder is 3 times the diameter
=> the height is 18cm
the volume of the cylinder is 3,14.18.(6/2)² = 508,68
because 3 spheres have the same diameter
=> the volume of 3 spheres is 4.3,14.3³ = 339,12
=> the volume of the cylinder that is left empty is 508,68 - 339,12 = 169,56
Step-by-step explanation:
Answer:
The answer is 508,68
Step-by-step explanation:
Since the volume of the cylinder is equal to the area of the permanent base multiplied in the height
Since the radius of the base is equal to 3 and since the area of its cylinder is equal to
[tex]314 \times 3 \times 3 = 28.26[/tex]
When the height equal to 18
Then the volume equal to
[tex]28.26 \times 18 = 508.68[/tex]

Answer:
a = -b + 10x + 9/ x
Step-by-step explanation:

c) Simplify fully
(5x – 10x2) /(14x - 7)
Answer:
- [tex]\frac{5x}{7}[/tex]
Step-by-step explanation:
Given
[tex]\frac{5x-10x^2}{14x-7}[/tex] ← factor out 5x in the numerator and 7 in the denominator
= [tex]\frac{5x(1-2x)}{7(2x-1)}[/tex] ← factor out - 1 on the numerator
= [tex]\frac{-5x(2x-1)}{7(2x-1)}[/tex] ← cancel the common factor (2x - 1)
= - [tex]\frac{5x}{7}[/tex]

Determine whether the expression is a polynomial. If it is a polynomial, find the degree
and determine whether it is a monomial, binomial, or trinomial.

hello again !
this isn't classified as a polynomial because polynomials do not contain variables raised to a negative number, such as this, which is raised to -3.
The volleyball team needs new uniforms. The students plan to sell plush toy eagles (the school mascot) for $5 each. The students find three companies on-line that sell stuffed mascots. Company A sells 12 eagles for $34.56. Company B sells 15 eagles for $42.90. Company C charges $51.30 for 18 eagles. Which company has the best buy?
Answer:
Step-by-step explanation:
A=34.56/12=$2.88 each
B=42.90/15=$2.86 each
C=51.30/18=$2.85 each
So C is the cheapest.
An obtuse triangle has two angles that measure 28° and 102°, what is the measure of the third side?
Answer:
50 degrees
Step-by-step explanation:
Well, all triangle's angles should add up to 180, so
102+28=130
180-130=50

Answer:
D
Step-by-step explanation:
If you multiply one side by 4, you have to multiply both sides by 4. D is the only one who multiplies both sides by 4, so it is the correct answer.
Martha rented a sedan at a cost of $21.25 a day for three days. She drove 980 miles at 25 cents a mile. Gas cost $63.45 what was the cost per mile
Answer:
38 cents per mile
Step-by-step explanation:
Let us first calculate the total expenditure by Martha
= 21.25*3= $ 63.75
Cost of gas =$ 63.45
Therefore cost per mile = 127.2/980= 0.1297+0.25= $0.3797 or 38 cents per mile
solve for m
–m + 8 = –4m − 10
Answer:
m=-6
Step-by-step explanation:
-m + 8 = -4m -10
+m. +m.
8= -3m -10
+10. +10
18 = -3m
/-3m /-3m
-6=m
Answer:
m=-6
Step-by-step explanation:
–m + 8 = –4m − 10
Subtract 8 from both sides
-m+8-8=-4m-10-8
Simplify:
-m=-4m-18
Add 4m to both sides
-m+4m=-4m-18+4m
Simplify:
3m=-18
Divide both sides by 3
3m/3=-18/3
-18/3=-6
m=-6

Brad has $75 in his savings account and adds $25 every month he doesn't make any withdrawals from the account which inequality shows the number of months it would take Brad to save at least $200
The inequality representing the problem will be x+3 ≥ 8
What is inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, Brad has $75 in his savings account and adds $25 every month he doesn't make any withdrawals from the account, and saves at least $200.
Let the number of months be x,
75 + 25x ≥ 200
25(3+x) ≥ 200
x+3 ≥ 8
Hence, The inequality is x+3 ≥ 8

Elise had a credit card balance of -$120. She
made a payment of $70 this month. Write and
then evaluate a SUBTRACTION expression to
find her new credit card balance.
Answer:
15.50+n=325.00
Step-by-step explanation:
15.50+what she had in the bank already = what she has now
Step-by-step explanation:
Elise's new credit card balance is $-50.
Elise's credit card balance is negative. This means that she has withdrawn more money than she has deposited. Elsie thus owes the bank $-120. If she paid $70, the amount she owes would be reduced by $70.
Elise's new credit card balance = credit card balance + payment made
$-120 + $70 = $-50

f(4) is just asking what the y value is when x=4 which is 1
f(-3) = -4
This has no minimum or maximum because the range is all real numbers (the y value goes to infintiy and negative infinity)
f(3)=6
f(0)= 3
This has a minimum because the lowest y value possible is not infinity (it's 2)

Complete the equation of the line whose y-intercept is (0,5) and slope is -9.
y=
Answer: y=-9x+5
Step-by-step explanation:
slope intercept form is y=mx+b
simply plug in the values.
m= the slope
the slope you gave was -9, so plug that in to m.
b= the y intercept aka when the number touches the y axis. in this case, it would be 5.
y=-9x+5
