Answer:
Total no of bracelets = 5s+28
Step-by-step explanation:
Let Sarah made s bracelets.
Maria made 7 more than Sarah i.e. 7+s
Julie made 3 times as many as Maria i.e. 3(7+s)
Total no of bracelets made is equal to the sum of the bracelets made by Sarah, Maria and Julie.
Total = s+ 7 + s + 3(7+s)
= 2s+7+21+3s
=2s+3s+21+7
= 5s+28
So, there are (5s+28) bracelets.

Two opponents Playing chess start out with 32 pieces on the chess board . Each person loses an equal amount of pieces over 15 minutes . By this time , only 20 piece remain . How many pieces did each person lose ?
Answer:
Each individual lost 6 pieces
Step-by-step explanation:
Initially, there were 32 pieces
After a while, 20 was left
The number of pieces lost will be 32-20 = 12 pieces
We are told that equal number of pieces were lost
So the number of pieces lost per individual will be:
12/2 = 6 pieces
PLEASE SHOW FULL SOLUTIONS. WILL MARK BRAINLIEST FOR THE BEST ANSWER. What is the approximate length of the fence around the field shown below? THANK YOU....
9514 1404 393
Answer:
398.12 m
Step-by-step explanation:
The perimeter fence consists of two half-circles (hence, a full circle) of radius 36.5 m, and two straight lengths of 84.39 m.
The circumference of a circle is given by the formula ...
C = 2πr
so the circular sections of fence have a total length of ...
C = 2π(36.5 m) = 73π m ≈ 229.34 m
__
Adding the two straight lengths to this gives a total perimeter of ...
P = 2(84.39 m) +229.34 m = 398.12 m
The approximate length of the fence around the field shown is 398.12 m.
_____
Comment on significant figures
Since the length of the straight section is given to the nearest cm, we have elected to give the total length accurate to the nearest cm. If we assume that the radius is only good to 3 significant figures, then the circumference of the circle is good only to 3 significant figures (229 m). Thus, we must give our approximate value to the same precision, the nearest meter: 398 m.
I got the measurements but i dont know how to put it in a sentence that makes sense
A rectangle with vertices J(2, 0) K(0,0) L(0,8) and M(2, 8) is rotated around the y-axis.
A. Use complete sentences to describe the resulting solid. Include the specific measurements for the solid’s dimensions such as height, width, length, radius, etc.
B. To the nearest tenth of a cubic unit, what is the volume of the resulting three-dimensional figure? Include all of your calculations.
Answer:
after graphing the points, describe the shape, (ex, rectangle) then mesure the points of the width, hight, or any other things. then multiply the length and the heaght and the thickness to get b

Step-by-step explanation:
Given the function f(x) = –22 – 7x + 18, determine the average rate of change
of the function over the interval -10 < x < -1.
Note: May be you meant to write the function as:
f(x)=-22x²-7x+18
Answer:
The Average rate of function = 235
Step-by-step explanation:
Given the function
f(x) = –22x² – 7x + 18
Interval = -10 < x < -1
so
taking x₁ = -9, x₂ = -2 in the interval
f(x₁) = f(-9) = -22(-9)² – 7(-9) + 18
= -1701
f(x₂) = f(-2) = -22(-2)² – 7(-2) + 18
= -56
Using the formula
Average rate of change = f(x₂) - f(x₁) / x₂-x₁
= (-56) - (-1701) / (-2) - (-9)
= (-56 + 1701) / (-2+9)
= 1645 / 7
= 235
Thus, the Average rate of function = 235
A car is traveling at a steady speed. It travels 2 1/3 miles in 3 1/2 minutes. How far will it travel in 38 minutes In 1 hour
Answer:
a) distance traveled is 16 miles.
b) distance traveled is 40 miles.
Step-by-step explanation:
Speed is a scalar quantity which describe the rate of distance moved with time.
i.e speed =
Given that: distance = 2 1/3 miles = miles, time = 3 1/2 minutes = minutes.
Then;
speed = ÷
= x
=
The car's steady speed is 0.67 miles per minute.
a) when the time is 24 minutes, the distance covered can be determine by:
distance = speed x time
= x 24
= 16
distance traveled is 16 miles.
b) When the time is 1 hour (60 minutes), the distance traveled can be determined by:
distance = speed x time
= x 60
= 40
distance traveled is 40 miles.

Ruiz needs to buy a countertop for a kitchen. He calculated the area to be 16 square feet. The actual area is 15.4 square feet. What is Ruiz's percentage error?
0.6%
3.75%
3.9%
6%
Answer: 3.9%
Step-by-step explanation:
First, subtract the two values:
16 - 15.4 = 0.6
Now divide this to the actual area:
0.6 / 15.4 = 0.038961039
Multiply by 100:
0.038961039 * 100 = 3.8961039
So the percent error is approximately 3.9%
Answer:
3.75% Hope it helps

Jordan bikes at a speed of 8 2/3 mph. How many miles will he bike in:
Answer:
the distance covered is 26.87 miles
Step-by-step explanation:
The computation of the distance covered is shown below:
As we know that
Speed = Distance ÷ Time
where
Speed is 8 2 ÷ 3 = 26 ÷ 3
And, the time required is 3 hours and 6 minutes i.e. 3 hours and 6 ÷ 60 = 3.1 hours
Now the distance covered is
= 26 ÷ 3 × 3.1
= 26.87 miles
hence, the distance covered is 26.87 miles

solve the equation below for x when y= 290
Answer:
If y = 290, x = 30
Step-by-step explanation:
y = 200 + 3x If y = 290
290 = 200 + 3x
290 - 200 = 3x
90 = 3x
90/3 = x
30 = x

Luis and olivia are saving money to buy their favorite candy at the store. For every $5 Luis saves, Olivia saves $7. After a week, Luis saves $42 less than Olivia. If there favorite candy cost $2.50 per pack, how many packs of candy can each of them buy
Given :
Luis and Olivia are saving money to buy their favorite candy at the store.
For every $5 Luis saves, Olivia saves $7.
After a week, Luis saves $42 less than Olivia.
To Find :
If there favorite candy cost $2.50 per pack, how many packs of candy can each of them buy.
Solution :
Ratio of money saved by Olivia and Luis is 7/5 .
Let, money save by Olivia is x.
So, money saved by Luis is x - 42 .
[tex]\dfrac{7}{5}=\dfrac{x}{x-42}\\\\7x - 294 = 5x\\\\x =\$ 147[/tex]
Money saved by Luis, $105 .
Number of pack Olivia can buy is, = 147/2.5 = 58.8 = 58 packets.
Number of pack Luis can buy is, = 105/2.5 = 42 packets.
Therefore, Olivia and Luis can buy 58 and 42 packets respectively.

2x+21/3 =5
x = -1
Simply get the variable on one side of the equation alone and simplify:
2x = 5 - 21/3
2x = 15/3 - 21/3
2x = -6/3
2x = -2
x = -1
