At a swim meet 20 medals were a warded. Four were gold metals 45% of the metals were silver the rest were bronze. What percent of the medals awarded were bronze
Answer:
35%
Step-by-step explanation:
To figure out the percentage of bronze medals, we must figure out the percentages of the gold and silver medals first.
We already know that 45% of the medals were silver.
We know that 4 of the 20 medals were gold.
4/20 as a percentage would be 20/100, or 20%.
So, 20% of the medals were gold, and 45% of them were silver.
45% + 20% = 65%
100% - 65% = 35%
So, 35% of the medals awarded were bronze.

Write an inequality for the situation. Use x as your variable.
Mrs. Treble charges her music students $25 per lesson plus a recital fee of $30. How many lessons can Melinda take if she wants to pay less than $155?
Answer:
Inequality: 25x + 30 < 155
Step-by-step explanation:
25x is the cost per lesson. 30 is the recital fee. 155 is the total cost. We used the < sign because she has to pay LESS than $155.
Solve...
25x + 30 < 155
Subtract 30 on both sides...
25x < 125
Divide 25 on both sides...
x < 5
THATS NOT YOUR ANSWER YET Always make sure to plug in the answer you got BEFORE inputting it.
Plug in 5 for x...
25 ( 5 ) + 30 < 155
125 + 30 < 155
155 < 155
You know that she wants to spend LESS than $155, when she takes 5 lessons, as shown above, she spends exactly $155, your answer would be 4 because she spends less than $155 when taking 4 classes, but exactly $155 when taking five.

divide rupee 560 between ramu and muni in the ratio of 3:2
Step-by-step explanation:
Let the divided amount between ramu and muni be 3x and 2x respectively.
Then
3x + 2x = 560
5x = 560
x = 560/ 5
x = 112
Amount received by Ramu
= 3 * 112 = 336
Amount received by muni
= 2 * 112 = 224

A. It is equally likely to be A, B, C, or D.
B. It is more likely to be D because it has not been landed on.
C. It is more likely to be C because it has landed on C the most.
D. It is not likely to be D because it has not been landed on.
Answer:
the answer would be A.
Step-by-step explanation:
because it done not matter how many times the spinner has landed on a certain letter it is still always gonna be a 1/4th chance to land on any letter

OC)
OD)
Answer:
The equation would help determine the cost 1 rubber stamps will be:
[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]
Step-by-step explanation:
Let x be the cost of 11 rubbers.
As the cost of 5 rubber stamps is $9.70.
Thus, the cost of 11 rubbers can be determined using the proportional ratios.
[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]
BONUS! let us solve to check
[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]
switch sides
[tex]\frac{x}{11}=\frac{9.7}{5}[/tex]
Multiply both sides by 11
[tex]\frac{11x}{11}=\frac{9.7\cdot \:11}{5}[/tex]
Simplify
[tex]x=21.34[/tex]
Thus, the cost of 11 rubber stamps: x = $21.34
Therefore, the equation would help determine the cost 1 rubber stamps will be:
[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]
VERIFICIATIONGiven
The cost of 5 rubber stamps = $9.70
Thus,
The cost of 1 rubber stamps = 9.70 / 5
= $1.94
If the cost of 1 rubber stamp = $1.94
The cost of 11 rubber stamps = 11 × 1.94
= $21.34

A coffee maker priced at $189.99 is on sale for 20% off but then sales tax of 9% and 8% are added to the price after discount. What will be the final sale price with taxes?
RIGHT ANSWER WILL BE MARKED BRAINLIEST
Answer:
20%+9%+8%=37% so 189.99*37/100=70.3$ so 189.99-70.3=119.7$
The final sale price of the coffee maker with taxes is $178.03.
How to calculate the final sale price?To find the final sale price of the coffee maker with taxes, we need to first calculate the discount and then add the tax amounts to the discounted price.
The discount on the coffee maker is 20/100 × $189.99 = $37.998.
So the price of the coffee maker after the discount is:
$189.99 - $37.998 = $152.992.
Then, we need to add the sales tax amounts to this price.
The sales tax amounts are 9/100 × $152.992 = $13.7993
And 8/100 × $152.992 = $12.23936.
The total tax amount is $13.7993 + $12.23936 = $26.03.
Therefore, the final sale price of the coffee maker with taxes is :
$152.992 + $26.03866 = $178.03
This is the final price that the customer will pay for the coffee maker.
