The 1st question-Elena is organizing her craft supplies. She estimates that her jars will fit 1,000 buttons or 50 large beads.they actually fit 677 buttons or 22 large beads. does Elena's estimate about the buttons or her estimate about the large beads have less percent error> to the nearest percent, how much less? show your work
The 2nd question-Kevins weekly salary is $865. He receives a 25% raise. How can kevin find his new weekly salary? select all that apply
A. divide 865 by 0.25
B. divide 865 by 1.25
C. multiply 865 by 0.25
D. multiply 865 by 1.25
E. add 865 and 1/4 of 865
F add 865 and 1 1/4 of 865
last question im gonna make on another one of these
Answer:
C
Step-by-step explanation:
0.25 x 865
Answer:
Step-by-step explanation:
1,,,To determine which estimate has a lower percent error, we need to calculate the percent error for each estimate and compare them.
Percent error can be calculated using the formula:
percent error = [(actual value - estimated value) / actual value] x 100%
For the buttons estimate:
percent error = [(677 - 1000) / 1000] x 100% = -32.3%
For the large beads estimate:
percent error = [(22 - 50) / 50] x 100% = -56%
Since the percent error for the large beads estimate (-56%) is larger than the percent error for the buttons estimate (-32.3%), Elena's estimate about the buttons has less percent error.
To determine how much less, we can subtract the two percent errors:
percent error difference = (-56%) - (-32.3%) = -23.7%
Rounding to the nearest percent, Elena's estimate about the buttons has 24% less percent error than her estimate about the large beads. 2,,,w weekly salary after a 25% raise, we can multiply his current weekly salary by 1.25 (which represents a 125% increase, since 100% + 25% = 125%). So, the correct answers are:
D. Multiply 865 by 1.25.
E. Add 865 and 1/4 of 865.
The steps for each option are:
A. Divide 865 by 0.25: This will not give Kevin's new salary after the raise. Instead, it will give the amount of the raise itself (since 25% of 865 is $216.25). To find the new salary, we need to add the raise amount to his original salary.
B. Divide 865 by 1.25: This will also not give Kevin's new salary after the raise. Instead, it will give his salary before the raise (since 865 ÷ 1.25 = 692, which is 100% of his original salary). To find the new salary, we need to multiply his original salary by 1.25.
C. Multiply 865 by 0.25: This will also give the amount of the raise itself (since 25% of 865 is $216.25). To find the new salary, we need to add the raise amount to his original salary.
D. Multiply 865 by 1.25: This will give Kevin's new weekly salary after the 25% raise.
E. Add 865 and 1/4 of 865: This is equivalent to multiplying 865 by 1.25, so it will also give Kevin's new weekly salary after the 25% raise.
F. Add 865 and 1 1/4 of 865: This is not a correct way to calculate Kevin's new weekly salary after the raise, since 1 1/4 of 865 is not a valid percentage increase.
