A florist orders roses and carnations. The roses cost $16 per dozen, and the carnations cost $9 per dozen. The florist orders a total of 18 dozens of roses and carnations for a total cost of $218.
How many dozens of roses does the florist order?
A. 6 dozen
B. 8 dozen
C. 10 dozen
D. 12 dozen
Answers
Answer:
B. 8 dozen
Step-by-step explanation:
Let r = number of dozens of roses.
Let c = number of dozens of carnations.
c + r = 18
9c + 16r = 218
-9c - 9r = -162
9c + 16r = 218
7r = 56
r = 8
Answer: B. 8 dozen
Answer: Its 8 dozen
Step-by-step explanation: 1. you multiply 8 times 16 and you get $128
2. you then multiply the remaining carnations by 9. 9 times 10 is $90
3. $128 + $90 is $218

Answers
Answer: hope this helps ♡
1.) x = -21
2.) x = 18
3.) x = 3
Step-by-step explanation:
(minus&minus = plus) (minus&plus = minus) (plus&minus = minus)
1.) 25 - 3x = 88
25 - 25 - 3x = 88 - 25
-3x = 63
-3x ÷ 3 = 63 ÷ 3
-x = 21 → x = -21
2.) -11 = 7 - x
-11 - 7 = 7 -7 -x
-18 = -x
18 = x → x = 18
3.) 95 = -4 + 33x
95 + 4 = -4 + 4 + 33x
99 = 33x
99 ÷ 33 = 33x ÷ 33

Answer:
25 gallons35 gallonsStep-by-step explanation:
You want the number of gallons of gas used by car 1 at 25 mpg and car 2 at 40 mpg when the total gas used for driving 2025 miles is 60 gallons.
SetupLet x represent the number of gallons used by car 2 at 40 miles per gallon. Then the gas used by car 1 is (60 -x). The number of miles driven is the product of miles per gallon and gallons used.
25(60 -x) +40x = 2025 . . . . total miles driven
SolutionSimplify the equation:
1500 +15x = 2025
15x = 525 . . . . . . . . . . subtract 1500
x = 35 . . . . . . . . . . divide by 15
60-x = 25 . . . . . gallons used by car 1
The first car used 25 gallons; the second car used 35 gallons.

Additional comment
The first car drove 25·25 = 625 miles; the second car drove 40·35 = 1400 miles.

Nadia is a stockbroker. She earns 12% commission each week. Last week, she sold $6,400 worth of stocks. How much did she make last week in commission? If she averages that same amount each week, how much did she make in commission in 2011?
Answers
Answer:
Nadia made a commission of 768 last week
The amount she made in 2011 is 40,045.824
Step-by-step explanation:
What is a commission?
A commission is the fee got for the services, given by the percentage of the total worth.
If Nadia gets a 12% commission for $6400,
Commission = percentage × worth of stock
= 12% × 6400
= 768
There are 52.143 weeks per year.
The amount of commissions she made in 2011 is,
768 × 52.143 = 40,045.824
Hence, Nadia made a commission of $852 for $6400 worth of stocks. If she averages the same amount each week, Nadia made a commission of $40,045.824

Step-by-step explanation:
solve for y:
y=180-125
Y=55
Solve for x:
x=180-(105+55)
x=20
Answer:
All 3 angles ultimately have to equal 180.
We have 1 angle known which is 105.
The other number given is 125 and the angle right next to it added with 125 should also equal 180.
180-125=55
Second angle is 55
Add the two angles known,
55+105=160
180-160= 20
x= 20
Check:
105+55+20=180 so its true

Find the measure of ∠YOZ by answering the questions.
1. Find the measure of ∠WOV. Which angle relationship did you use? (3 points)
2. Now find the measure of ∠YOZ. Which angle relationship did you use? (3 points)
3. Check your answer by using another strategy to find the measure of ∠YOZ. Describe your strategy, and show that it gives the same measure for ∠YOZ. (4 points)
Answers
Answer:1. The measure of ∠WOV is 60°. You would use complementary angles that are adjacent (∠WOV, and ∠XOW)
2. The measure of ∠YOZ is 60°. You would use the vertical angles that are non-adjacent (∠WOV, and ∠YOZ). These two angles are congruent so they would have the same measure. These angles combined also create supplementary angles
3. Another way to find the measure of ∠YOZ would be to make/write an equation and solve for x. For example, (3x+30)°=60°. x would equal 10 because 10x3=30+30=60°
Step-by-step explanation:
1. Since a complementary angle would equal 90°, simply subtract 30° from 90° resulting in 60°.
2. Because vertical angles are congruent and (∠WOV, and ∠YOZ) are a pair of them, they equal the same as each other so they're both 60°.
3. You can make any equation with x included as long as it equals 60° mine was just an example you can make your own like 10x+10=60 or 4x+20=60. Also to create your equation you also need to use the angle fact of the vertical angles
Calculate the volume of a cone with a height of 6 inches and a diameter of 6 inches.
Leave your answer in terms of PI
Answers
Answer: Volume ≈ 56.55
Step-by-step explanation:
56.54867 is the answer, but I rounded it. I hope this helped! :)
Answer:
18π cubic inches
Step-by-step explanation:
First, we need to find the radius of the cone, which is half of the diameter.
radius = diameter/2 = 6/2 = 3 inches
The formula for the volume of a cone is:
V = 1/3 × π × r^2 × h
where r is the radius of the base of the cone, and h is the height of the cone.
Substituting the values we get:
V = 1/3 × π × 3^2 × 6
V = 1/3 × π × 9 × 6
V = π × 18

What is angle 2?
Answers
Answer: 145
Step-by-step explanation: 180 is a staight line so 180-35=145 would make sense
We can tell they are supplementary because they both make up one straight line.
35° + Angle 2 = 180°
Subtract 35° on both sides.
Angle 2 = 145°
