Divide 17.9 by 2.38. Round your answer to the nearest tenth.
0.7
7.5
0.8
7.6
Answer:
7.5
Step-by-step explanation:
You divide 17.9 by 2.38. That would give you 7.521008403361345.
Rounding to the nearest tenth would mean to round till you have a number right after the decimal point. When you round, you would get 7.5 since 2 isn’t enough to change the five to a six.
Hope that helps!! Have an amazing day!!

1. A light bulb is one-hundredth of an inch thick, with an allowable error of 2%. What is the least allowable thickness of the filament?
A. 0.00098
B. 0.0002
C. 0.0098
D.0.0102
Answer:
Answer:
0.00998 Inches
Step-by-step explanation:
Thickness of the light bulb filament = 0.01 Inch
Allowable error = 2%.
2% of 0.01 = 0.02 X 0.01 =0.0002 Inch
Therefore, the allowable thickness of the bulb filament
We can then calculate the least allowable thickness of the filament as:
The least allowable thickness of the filament is 0.00998 Inches.
Answer:
C. 0.0098
Explanation:
one-hundredth of an inch: 1/100 ≈ 0.01 (inch)
Upper-bound (maximum error):
= 0.01 × (100% + 2%)
= 0.01 × 102%
= 0.0102 inches
Lower-bound (minimum error):
= 0.01 × (100% - 2%)
= 0.01 × 98%
= 0.0098 inches
Hence, the greatest allowable thickness of filament is 0.0102 inches and mostly the least allowable thickness is 0.0098 inches, which is the answer.
please help me with this math question Graph this line using the slope and y-intercept:
Answer:
(8,1) (15,2) (22,3) (29,4) (36,5) (43,6)
Step-by-step explanation:
Answer:
Step-by-step explanation:
The equation y=7x+1 is written in slope intercept form. That would be:
y=mx+b
m is the slope
b is the y intercept, or where the line first is seen on the y axis.
Because b=1, the y intercept is 1.
Because m=7, the slope is 7.
STEP 1: GRAPH THE Y INTERCEPT.
Since b=1, the line crosses the y intercept when y=1. So graph y=1 on the coordinate plane.
STEP 2: GRAPH THE SLOPE
Do this by going up 7, then right 1. Because 7 is a positive number, you go up.

A local gym sells monthly memberships. The function f(x) = −x2 + 18x − 72 models the daily profit in dollars, where x is the number of memberships sold.
Determine the zeros, and explain what these values mean in the context of the problem.
x = 9, x = 18; The zeros represent the number of monthly memberships that produces a maximum profit.
x = 9, x = 18; The zeros represent the number of monthly memberships when no profit is made.
x = 6, x = 12; The zeros represent the number of monthly memberships that produces a maximum profit.
x = 6, x = 12; The zeros represent the number of monthly memberships when no profit is made.
Answer: the zeros are at (6,0) and (12,0) where no profit is made.
option D
Step-by-step explanation: you can find the zeros ( the x-intercepts), by either graphing out the function or factoring it.
in this scenario, there is no y increase, which means 0 profit.

The area of the garden was 2¾yd². If the length is 1 ½ yd, find
the width.
Answer:
11/6 or 1 5/6yards
Step-by-step explanation:
Area = Length x Width
2 3/4 = 1 1/2 w
11/4 = 3/2w to change 2 3/4 into an improper fraction see this as 2 wholes plus 3/4. Another name for 2 wholes is 8/4 then add the 3/4. 8/4 + 3/4 is 11/4.
Do the same for 1 1/2 which is 1 + 1/2 change 1 into 2/2 and add it to 1/2 which would be 3/2.
Now solve for x
(2/3) (11/4) = (3/2) (2/3) w when I multiply 3/2 by its reciprocal of 2/3, I get the number 1 and 1 times w is just w.
22/12 =w. I just multiplies the tops with the bottoms. Now, divide the top and the bottom by 2 and you end up with 11/6. If I divide 11 by 6, it will go into 11 one time with 5 left over. The denominator remains 6.
Answer:
Step-by-step explanation:
The area A of a rectangle of length L and width W is A = L*W. Solving this for W, we get A/L.
Substituting 2 3/4 yd^2 for A and 1 1/2 yd for L, we get:
W = (2 3/4 yd)^2 / (1 1/2 yd)
This is equivalent to (11/4 yd^2 divided by (6/4 yd), or 11/6 yd.
The width of this garden is 11/6 yard, or 1 5/6 yard.

Find the area
of the figure.
Answer:
first the triangle
t area=b x h ÷2
=(5ft x 10.5ft)÷2
=26.25ft sq unit
second the rectangle
r area=L × b
=9ft × 7.5ft
=67.5ft sq unit
last the triangle
t area= b×h÷2
=(9ft×4.5ft)÷2
=20.25ft sq unit
Total area= 26.25ft+65.5ft+20.25ft =112ft sq unitAnswer:
110.25 ft^2
Step-by-step explanation:
We can find the area of the figure by adding up the areas of three different shapes.
1) The right triangle
The formula for finding the area of a right triangle is: Base x Height x 1/2
The base in the right triable is 5 and the height is 9.
--> 5 x 9 x 1/2
--> 45/2
--> 22.5
2) The rectangle
The formula for finding the area of a rectangle is: Base x Height
The base is 7.5 and the height is 9.
--> 7.5 x 9
--> 67.5
3) The Isosceles Triangle (On the very right)
The formula for finding the area of a right triangle is: Base x Height x 1/2
The base of the triangle is 9, and the height is 4.5.
--> 9 x 4.5 x 1/2
--> 40.5/2
--> 20.25
Now that we know the areas of separate shapes, all we need to do is add them up!
22.5 + 67.5 + 20.25
= 110.25.
The area of the figure is 110.25 ft^2

3 friends shared 48 pineapples equally among themselves. One of the friends sold all his pineapple each at $5 how much did he get from selling the pineapples?
Answer: $80
Step-by-step explanation:
Step 1: Find how much each person got
48 pineapples shared amongst 3 people
48÷3= 16 pineapples each
Step 2: Find how much he earned
16 pineapples for $5 each
Total money made: 16x5= 80
$80 in all selling his share of the pineapples
hope this helps!!
The total amount of money the friend made from selling his pineapples is $80
How much did he get from selling the pineapples?Total pineapples = 48
Total friends = 3
Number of pineapples each friend takes = Total pineapples / Total friends
= 48/3
= 16 pineapples per friend
Cost of each pineapple = $5
Total amount the friend made from selling his pineapples = Cost of each pineapple × Number of pineapples each friend takes
= $5 × 16
=$80
Hence, the friend made $80 from selling his pineapples.

John has decided to prepare an old field for his son's new horse. the length of the field is 10 meters less than 4 times its width. He will spend $1,584 on fencing for the field at a cost of $4.80 per meter. He also needs to buy sweetgrass seed to plant in the field. The seed costs $3.98 per bag and each bag covers 460 square meters. If John has $1,600, is this enough money to purchase the fence and all the seeds needed to plant in this field?
Answer: The total money invested in the field will be $1,623.80
Step-by-step explanation:
step 1
Find the dimensions of the field
Let
x -----> the length of the field
y -----> the width of the field
p=2(x+y)
p(4.80)=1,584
p=330m
we know that
The perimeter of the field is equal to
so
330=2(x+y)----> equation A
x=4y-10 ------> equation B
substitute equation B in equation A and solve for y
330=2(4y-10+y)
165=(5y-10)
5y=165+10
y+35
Find the value of x
x=4(35)-10+130
therefore
The length of the field is 130 meters and the width of the field is 35 meters
step 2
Find the area of the field
The area of the field is
A=xy
substitute
A=(130)(35)=4,550m2
step 3
Find the number of bags of seed
Divide the area by 460
4,550/460=9.89 bags
Round up to the nearest whole number
9.89 bags=10 bags
step 4
Find the cost of the seed
(10 )(3.98)=$19.8
step 5
Find the total money invested in the field
