Answer: 1/20 pounds
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Modeling clay available: 1/2lb Modeling clay used: 1/5 lb on Tuesday and 1/4 on Tuesday.So, we have to subtract the amount of clay used (1/5 +1/4) to the amount of clay available (1/2).
Mathematically speaking:
1/2 lb - ( 1/5 lb +1/4 lb) =
1/2 lb - 9/20 lb = 1/20 lb = 1/20 pounds

Solve. Note the equal sign. What you do to one side, you do to the other. Remember to follow PEMDAS.
First, distribute 5 to all terms within the parenthesis
5(w - 1) = (5)(w) + (5)(-1) = 5w - 5
Next, simplify. Combine like terms
5w - 5 - 2 = 5w + 7
5w - 7 = 5w + 7
Next, isolate the variable. Add 7 to both sides, and subtract 5w from both sides
5w (-5w) - 7 (+7) = 5w (-5w) + 7 (+7)
5w - 5w = 7 + 7
0 = 14 (Untrue).

An airplane flew at an average rate of 600 miles per hour from Tokyo to Seattle. Because of a strong headwind, the average rate of the return trip was only 480 mph. The round trip took 18 hours. Which equation can be used to determine the time for each leg? 600t = 480t 600t = 18 – t 600t = 480 – t 600t = 480(18 – t)
600t = 480(18 – t) should be it
Answer:
Option D. 600t = 480( 18-t )
Step-by-step explanation:
An airplane flew at an average rate of 600 miles per hour fro Tokyo to Seattle.
Let the airplane travels for t hours so distance covered by the airplane will be = speed × time
= 600t miles
Similarly, average speed in return trip was 480 mile/hour. So distance covered in return trip = speed × time
= 480 ( 18-t ) [ since time taken by plane in round trip was 18. So time taken in return trip will be ( 18-t) ]
Therefore, distance traveled in one trip = distance covered in return trip
600t = 480( 18-t )
Option D is the answer.
A rectangle has a width of 7.9ft and a perimeter of 27.2 Ft enter the length of the rectangle, in decimal form in the box
Answer:
The length is 5.7 feet.
Step-by-step explanation:
A rectangle has a width of 7.9 feet and a perimeter of 27.2 feet.
Let the length be = x
Perimeter is given by :
[tex]P=2(L+W)[/tex]
We get;
[tex]27.2=2(x+7.9)[/tex]
=> [tex]27.2=2x+15.8[/tex]
=> [tex]2x=11.4[/tex]
Dividing both sides by 2 to get x;
x = 5.7 feet
Hence, length is 5.7 feet.
For what values of x is the quantity x-7
positive = greater than 0.
Therefore we have the inequality:
[tex]x-7 > 0[/tex] |add 7 to both sides
[tex]x > 7[/tex]

Helga and Julie are sisters. Helga is six years younger than twice Julie's age. The sum of Helga's age and Julie's age is 36. Write an equation that can be used to find Julie's age, j. HELPPPPPPPPPPPPPPPPPPPPPPP
Julie's age based on the scenario given cab be obtained by using the equation ; j + 2j - 6 = 36
Let :
Julie's age = j ________(1)
Helga's age = 2j - 6 ____(2)
Sum of their ages = 36
Hence, to find Julie's age, j we can use the equation :
(1) + (2) = 36
j + (2j - 6) = 36
j + 2j - 6 = 36
To find Julie's age, we can use the equation ;
j + 2j - 6 = 36
3j - 6 = 36
3j = 36 + 6
3j = 42
j = 42 / 3
j = 14
Hence, Julie's age is 14 years.

You invest $2000 in an account at 4.5% per year simple interest. How much will you have in the account at the beginning of the 8th year? Round your answer to the nearest whole dollar.
A. $2560
B. $2640
C. $2720
D. $2630
answer is 2720
solution below
First, converting R percent to r a decimal
r = R/100 = 4.5%/100 = 0.045 per year.
solving our equation:
A = 2000(1 + (0.045 × 8)) = 2720
A = $2,720.00
the total amount accrued, principal plus interest, from simple interest on a principal of $2,000.00 at a rate of 4.5% per year for 8 years is $2,720.00
What is the equation for a line that passes through the points (-5,-4) and (10,23)?
So you use the point slope stuff.
y-y=m(x-x)
To find the slope, subtract two y values over two x values that are also sibtracted in the same order.
IN this case, you could do (-4 - 23)/-5 - 10
Which is 9/5
So now you plug in the x and y values (doesnt matter which point)
y+4=9/5(x+5)
Make it slope intercept form
y=9/5x-13
Lori creates the following design for a T-shirt.
Lori found the areas of Triangle 1 and Rectangle 1. Find the areas of the remaining figures.
The area of Rectangle 1 is 8.68 square inches.
The area of Triangle 1 is 6.48 square inches.
The area of Rectangle 2 is ... square inches.
The area of Triangle 2 is ... square inches.
The area of the whole figure is ... square inches.
Solution-
From the figure,
AE = 2.4
EB = 2.8
BC = 11.7
Area of rectangle 1 = 8.68 sq.in
[tex]\Rightarrow FH \times HI=8.68[/tex]
[tex]\Rightarrow EB \times HI=8.68[/tex] (∵ sides of the rectangle 2)
[tex]\Rightarrow 2.8 \times HI=8.68[/tex]
[tex]\Rightarrow HI=3.1[/tex]
Area of Triangle 1 = 6.48 sq.in
[tex]\Rightarrow \frac{1}{2}\times AE \times EG= 6.48[/tex]
[tex]\Rightarrow \frac{1}{2}\times AE \times (EF+FG)= 6.48[/tex]
[tex]\Rightarrow \frac{1}{2}\times AE \times (EF+HI)= 6.48[/tex] (∵ sides of the rectangle 1)
[tex]\Rightarrow EF+3.1= 5.4[/tex]
[tex]\Rightarrow EF=2.3[/tex]
[tex]\Rightarrow BH=2.3[/tex] (∵ sides of the rectangle 2)
[tex]BC = BH+HI+IC[/tex]
[tex]\Rightarrow 11.7= 2.3+3.1+IC[/tex]
[tex]\Rightarrow IC=6.3[/tex]
The area of Rectangle 2,
[tex]=EB\times BH =2.8\times 2.3=6.44\ sq.in[/tex]
The area of Triangle 2,
[tex]\frac{1}{2}\times GI \times IC=\frac{1}{2}\times EB \times IC=\frac{1}{2}\times 2.8 \times 6.3=8.82\ sq.in[/tex]
The area of the whole figure = Area of Triangle 1 + Area of rectangle 1 + Area of Triangle 2 + Area of rectangle 2
= 6.48+8.68+8.82+6.44=30.42 sq.in

Please!! The sum of the measures of the angles from any triangle is 180 degrees. In triangle ABC, angles A and B have the same measure, while the measure of angle C is 45 degrees larger than each of A and B. What are the measures of the three angles?
Let Angle A = X
Since Angle B is the same, angle B is also X
Then angle C = X +45
Add the 3 angles together: X +X +X +45 = 3x+45
That equals 180 degrees:
3x+45 = 180
Subtract 45 from both sides:
3x = 135
Divide both sides by 3:
X = 135/3
X = 45
Angle A = 45
Angle B = 45
Angle C = 45+45 = 90

A race horse that wins three 3200 meter cup in a time of 200 seconds. what is the race horses Average speed?
Answer:
16 meter per second.
Step-by-step explanation:
A race horse that wins three 3200 meter cup in a time of 200 seconds.
Since in 200 seconds horse can run = 3200 meter
Therefore, in 1 second horse can run = [tex]\frac{3200}{200}[/tex]
= 16 meter/second
1 hour = 3600 seconds
Therefore in 1 hour horse can run = 3600 × 16
= 57,600 meter/hour
The average speed of the horse would be 16 meter per second or 57,600 meter per hour.

Joe says that the product of a 4 digit number and a 1 digit number is always a 4 digit number does Joe's statement makes sense?
No, what Joe said isn't necessarily true. Though it is common that the product will be a 4 digit number, because you can use any number, like a large 4 digit number like 9999 or a large 1 digit number like 9, that isn't true. For instance: "9999 x 9" is 89991 which is 5 digits instead of 4 because "9999" is the biggest 4 digit number and "9" is the biggest "1" digit number.
Shane deposited $200 into an account and earned $36 in interest after 3 years. Use the formula I = prt, where I represents simple interest, p represents principal, r represents interest rate, and t represents time in years. What is the interest rate?
Answer:
The interest rate = 6 %
Explanation:
We have I = prt, where I represents simple interest, p represents principal, r represents interest rate, and t represents time in years.
Here principal, p = 200 $
Number of years , t = 3
Interest received, I = 36$
We need to find rate of interest.
Substituting
36 = 200 x r x 3
r = [tex]\frac{36}{200*3}[/tex]= 0.06 = 6%
The interest rate = 6 %
Answer:20%
Step-by-step explanation:
Let r represent rate of interest.
We have been given that Mika invested $200 into a certificate of deposit. After 6 months, the balance was $220.
We will use simple interest formula to solve our given problem.
I = Amount of interest,
P = Principal amount,
r = Rate of interest in decimal form,
t = Time in years.
First of all, we will find amount of interest by subtracting $200 from $220 as:
6 month = 1/2 year = 0.5 year
Upon substituting our given values in simple interest formula, we will get:
Upon dividing both sides by $100, we will get:
Since interest rate is given in decimal, so we will multiply 0.2 by 100 to convert our answer in percentage.
Therefore, the interest rate on the deposit was 20% and option B is the correct choice.
