Answer:
0.42
Step-by-step explanation:
The computation of the length of the remaining rope in inches is shown below:
Length Remaining = Length - the piece he cut off
Length Remaining = 60 - 18
60 - 18 = 42
To turn 42 into a decimal, you have to divide by 100 ↓
42 ÷ 100 = 0.42
The length of rope remaining is 0.42 inches long

Answer:
A) 3.44 ft²
Step-by-step explanation:
before cutouts, the area was 4 x 4 = 16 ft²
the circles have a diameter of 2 ft each, and a radius of 1 ft
each circle has an area pf (3.14)(1²) = 3.14 ft²
3.14 x 4 = 12.56 ft²
16 - 12.56 = 3.44 ft² left

david and jason have marbles in a ratio of 2:3. together they have a total of 35 marbles . how many marbles dose David have
Answer:
14 marble
Step-by-step explanation:
here's your solution
=> Total number of marble = 35
=> ratio of David and Jason = 2 : 3
=> let the ratio be in x
=> now, 2x + 3x = 35
=> 5x = 35
=> x = 35/5
=> x = 7
=> number of marble with David = 7*2 = 14
=> number of marble with Jason = 7*3 = 21
hope it helps
Answer:
number of marbles that David had=
[tex]35 \times \frac{2}{5} \\ 14marbles[/tex]
Ms. Xu is making dinner for her family, and she needs 3 pints of rice for her recipe. All of her measuring devices are in cups. How many cups of rice will she need?
Answer:
6 cups
Step-by-step explanation:
Recall:
1 pint = 2 cups
Required recipe = 3 pints of rice
To make the measurement using a cup ;
The number of cups of rice needed will be ;
1 pint = 2 cups
3 pints = x cups
Cross multiply
x = 3 *2
x = 6
Hence, 6 cups of rice will be needed

What shape is created by the rotation and what is the approximate circumference of the base? Circumference of a circle: C = 2πr
Answer:
50inches
Step-by-step explanation:
Complete question;
The square shown(image attached) has a perimeter of 32 units. The square is rotated about line k. What shape is created by the rotation and what is the approximate circumference of the base? Circumference of a circle: C = 2πr a cone with a base circumference of about 25 units a cone with a base circumference of about 50 units a cylinder with a circumference of about 25 units a cylinder with a circumference of about 50 units.
The figure shown is a square
Perimeter of a square = 4L
L is the length of the side of the square
32 = 4L
L =32/4
L = 8units
Since the square is rotated about a line k forming a circular shapr, hence the radius of the circular shape is equal to the length of the side of the rotated square. Hence r = 8units
Get the circumference of the circle
C = 2πr
Substitute r = 8 into the formula
C = 2π(8)
C = 16π
C = 16(3.14)
C = 50.24in
Hence the approximate circumference of the circle is 50inches

Identify the vertex (the 2 beside the "x" means squared)
y=-x2 + 18x - 72
Answer:
Write the problem as a mathematical expression.
y=−x²+18x−72
Rewrite the equation in vertex form.
y=−(x−9)²+9
Use the vertex form, y=a(x−h)2+k , to determine the values of a, h, and k.
a=−1
h=9
k=9
Find the vertex (h,k).

Answer:
Option (2)
Step-by-step explanation:
Amount of apples in a box = [tex]2\frac{3}{4}[/tex] pounds
= [tex]\frac{11}{4}[/tex] pounds
Apples used by Sage = [tex]\frac{1}{5}th[/tex] Part of the total amount
= [tex]\frac{1}{5}[/tex]th part of the apples in the box
= [tex]\frac{1}{5}\times \frac{11}{4}[/tex]
= [tex]\frac{11}{20}[/tex] pounds
Therefore, Sage used [tex]\frac{11}{20}[/tex] pounds of the apples.
Option (2) will be the answer.
When a=2 and b=-3, which expression has the largest value?.
A. 2a+3b
B. 3a+2b
C. 2a-3b
D. 3a-2b
help.
Answer: C
Step-by-step explanation:
At a = 2 and b = -3, the correct expression which has the largest value is,
⇒ 2a - 3b
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expressions are,
A. 2a+3b
B. 3a+2b
C. 2a-3b
D. 3a-2b
Put a = 2 and b = - 3 in expressions as;
A. 2a + 3b
⇒ 2 × 2 + 3 × - 3
⇒ 4 - 9
⇒ - 5
B. 3a+2b
⇒ 3 × 2 + 2 × - 3
⇒ 6 - 6
⇒ 0
C. 2a-3b
⇒ 2 × 2 - 3 × - 3
⇒ 4 + 9
⇒ 13
D. 3a-2b
⇒ 3 × 2 - 2 × - 3
⇒ 6 + 6
⇒ 12
Thus, Option C has the largest value.

~AH1807We are painting a rectangular wall of a large room. The dimensions of the wall are 35feet long and 21.5 feet wide. If the total cost of the paint was 421.40 what was the cost in dollars of the paint rounded to the nearest cent
Answer:
56 cent per ft²
Step-by-step explanation:
Wall dimension = 35 feets * 21.5 feets
Total cost of paint used = 421.40
Area of wall = Area of rectangle = Length * width
Area of wall = 35 feets * 21.5 feets
Area of wall = 752.5 ft²
Cost of paint per square feet:
Total coast of paint / Area of wall
$421.40 / 752.5 ft²
= $0.56 per ft²
= 0.56 * 100 = 56
0.4x - 1.2 = 0.15x + 0.8 ?????????
Answer:
x = 8
Step-by-step explanation:
0.4x - 1.2 = 0.15x + 0.8
0.4x - 1.2 + 1.2 = 0.4x
0.15x + 0.8 + 1.2 = 0.15x + 2
0.4x = 0.15x + 2
0.4x - 0.15x = 0.25x
0.15x + 2 - 0.15x = 2
0.25x = 2
0.25x / 0.25 = x
2 / 0.25 = 8
x = 8
Jason wants to add a fence to his yard to make it the shape of a rectangle. What is the measure of angle MKJ in the portion of the yard not inside the fence?
Answer:
[tex]\angle MKJ = 34[/tex]
Step-by-step explanation:
Given
[tex]\angle LKJ = 124[/tex]
Required
Find [tex]\angle MKJ[/tex]
From the attachment:
The measure of [tex]\angle MKJ[/tex] is calculated using the following expression:
[tex]\angle MKJ + \angle LKM = \angle LKJ[/tex]
Where
[tex]\angle LKM = 90[/tex] -- right-angled.
The expression becomes
[tex]\angle MKJ + 90 = 124[/tex]
[tex]\angle MKJ = 124 - 90[/tex]
[tex]\angle MKJ = 34[/tex]
