Mr. Ramirez purchased 20 concert tickets for a total of $225. The concert tickets cost $15 for adults and $10 for children under the age of 12
Answer: 5, 15
Step-by-step explanation:
Given
Mr. Ramirez purchased 20 concert tickets
The total price of 20 tickets is [tex]\$225[/tex]
Concert ticket costs [tex]\$15[/tex] for adults and [tex]\$10[/tex] for children
suppose there are x adults and y children
[tex]\therefore x+y=20\quad \ldots (i)\\\\\Rightarrow 15x+10y=225\quad \ldots(ii)[/tex]
Solving (i) and (ii) we get
[tex]x=5,\ y=15[/tex]
So, there are 5 adults and 15 children
Find the slope of the line that passes through the following points:
[tex]`\left(\frac{2}{5},\frac{2}{3}\right)\ \ \left(-\frac{4}{9},\frac{3}{5}\right)`[/tex]
Show the work/explain!
Answer:
3/50
Step-by-step explanation:
Slope m = y2-y1/x2-x1
From the coordinate
x1 = 2/5, y1 = 2/3, x2 = -4/9 and y2 = 3/5
Substitute;
m = (3/5 - 2/3)/-4/9-2/3
m = (9-10/15)/(-4-6/9)
m = -1/15/-10/9
m = -1/15 * -9/10
m = 9/150
m = 3/50
Hence the slope of the line passing through the points is 3/50

At the craft store, Kim bought a bag of marbles. In the bag there were 20 blue marbles and 30 green marbles. What percent of the marbles were green?
Answer:
60%
Step-by-step explanation:
percent of green marbles = (total number of green marbles / total number of marbles in the bag) x 100
total number of marbles in the bag = 30 + 20 = 50
30 / 50 x 100 = 60%
Answer:
60%

Help me find the area :)
Answer:
400 cm²
Step-by-step explanation:
25÷20 = 1.25
Area = 1.25 × 320
= 400 cm²
Answer:
500
Step-by-step explanation:
Base is 20, height is 16, the larger one is 1.25 times larger, so the height of the larger one is 16*1.25=20. This means that the area of the larger one is 20*25=500.

A sample of nitrogen gas has a pressure of 6.58 kPa at 539K. If the volume does not
change, what will the pressure be at -62C.
Answer:
2.575844
Step-by-step explanation:
This is a simple change of temp problem, from 539K to -62C but to start you have to change the C to K, which is simply adding 273 to the -62 so 211K.
Now you take P1/T1 = P2/T2 so,
6.58 = x
539 = 211
now cross multiply and divide, 211 x 6.58 then divide by 539.
this will give you your answer

L U C K luck is parallelogram with ∠C=68° and ∠LUK=42° find: 1.
m∠ CUK 2. m∠ K
Answer:
1. m∠CUK = 70°
2. m∠K = 112°
Step-by-step explanation:
1. The given parameters of the parallelogram LUCK are;
∠C = 68°
∠LUK = 42°
From the diagram of parallelogram LUCK obtained from an online source, we have;
Given that LUCK = A parallelogram, we have;
The same side interior angles ∠C and ∠U are supplementary angles
Therefore;
∠C + ∠U = 180°
∠U = 180° - ∠ C
∴ ∠U = 180° - 68° = 112°
∠U = 112°
By angle addition property, ∠U = ∠LUK + ∠CUK
∴ m∠CUK = ∠U - ∠LUK
By plugging in the value of ∠LUK = 42°, and ∠U = 112°, we have;
m∠CUK = ∠U - ∠LUK = 112° - 42° = 70°
m∠CUK = 70°
2. By angle addition property, we have;
∠K = ∠LKU + ∠CKU
∠LKU and ∠CUK are alternate interior angles
∴ ∠LKU = ∠CUK = 70°
Similarly, ∠CKU and ∠LUK are alternate interior angles
∠CKU = ∠LUK = 42°
m∠K = ∠LKU + ∠CKU = 70° + 42° = 112°
m∠K = 112°.

centimeters. If Howard's driveway
measures 1.75 dekameters long, how
many centimeters long is the driveway?
Explain your answer.
Answer quick PLZZ no website
Answer:
the number of centimeters is 1,750
Step-by-step explanation:
The computation of the number of centimeters is shown below;
Given that
1 dekameter = 1000 centimeter
And, there are 1.75 dekameters
So, the number of centimeter is
= 1000 × 1.75
= 1,750 centimeter long
Hence, the number of centimeters is 1,750
