The perimeter of a rectangular field is 364 yards. If the width of the field is 85 yards, what is its length?
Answer:
[tex]\huge\boxed{97 yards}[/tex]
Step-by-step explanation:
Important Information:
Perimeter of rectangle=[tex]Lenght+Length+width+width[/tex]
Method:
The first step to work this out is to multiply the width of 85 by 2, this gives you 170.This is because a rectangle has two sets of equal sides. This means that there two widths.
The next step is to subtract 170 from the perimeter of 364, this gives you 194. This is because the formula for the perimeter of a rectangle is[tex]Lenght+Length+width+width[/tex]. This means that in order to isolate the values of the lenght we must subtract the values of the width.
The final step is to divide the value of 194 by 2, this gives you 97. This is because that is the value for 2*the length. That means in order to work out the value of 1 you would need to divide by 2.
Step By Step:
1) Multiply 85 by 2.
[tex]85*2=170[/tex]
2) subtract 170 from 364.
[tex]364-170=194[/tex]
3) Divide 194 by 2.
[tex]194/2=97[/tex]

Step-by-step explanation:
this week in total = 100
4 more ( + ) 3 times ( x ) last
- - - - - -
100 - 4 = 96
96 x 3 = 288
either subtract or add
288 - 100 = 188

jack is thinking of two whole numbers
the sum of the number is 13
the difference between the numbers is 1
what is the product of the numbers
Answer:
Their product is 42
Step-by-step explanation:
Let the numbers be A and B
Such that:
[tex]A + B = 13[/tex]
[tex]A - B = 1[/tex]
Required
Determine A * B
Add both equations together:
[tex]A + A + B - B = 13 + 1[/tex]
[tex]2A = 14[/tex]
Solve for A
[tex]A = 7[/tex]
Substitute 7 for A in the second equation
[tex]7 - B = 1[/tex]
Make B the subject
[tex]B = 7 - 1[/tex]
[tex]B = 6[/tex]
Hence,
A = 7 and B = 6
So:
[tex]A * B = 7 * 6[/tex]
[tex]A * B = 42[/tex]
The product of the two numbers will be 42.
Let the two numbers be A and B
A + B = 13
A - B = 1
A = 1 + B.
Therefore, since A + B = 13, then (1 + B) + B = 13
1 + 2B = 13
2B = 13 - 1
2B = 12
B = 6
A = 6 + 1 = 7
Since the numbers are 6 and 7, then multiplying them is 42.

The ratio of 6th-grade students to 7th-grade students in a soccer league is 15:10. If there are 100 students in all, how many 7th graders are there? *
Answer:
40 7th grade students.
Step-by-step explanation:
Ok so first we know the total equals 100. In order to divide the number of 6th graders and 7th graders equally, we add 15 and 10 which equals 25. Now, 100 divided 25 equals 4. Boom! We multiply 15 by 4 and that equals 60. This means there are 60 6th graders. We multiply 10 by 4 which means there are 40 7th graders. Now to check if we did it all right we add 60 and 40 which equals 100 STUDENTS IN ALL. This means we did it right. So it asked us for the amount of 7th graders which is 40! Hope this helps.

The current, I, varies inversely to the resistance, R. If the current is 250 milliamperes
when the resistance is 5 ohms, find the current when the resistance is 20 ohms.
a) 124.5 milliamperes
b) 50 milliamperes
C)62.5 milliamperes
d) 1250 milliamperes
Answer:
C
Step-by-step explanation:
First find the voltage which is current times resistance. Convert milliamperes to amperes. Divide 250/1000 because amperes are 1000 times smaller. That results in 0.25. So multiply 0.25 A by 5 ohms. That is 1.25. Now divide 20 by 1.25 which is 0.0625. Convert that to millamperes by multiplying by 1000. That gives you 62.5 millamperes.

What’s the value of x?
Answer:
x=6
Step-by-step explanation:
We know that <AWV is 90, so we can set up an equation. This equation is 54+3x+18=90, we know this is true because the two smaller angles are complementary. Then to find x simply solve the equation.
First, add like terms
3x+72=90
Then, subtract 72 from both sides
3x=18
Finally, divide both sides by 3
x=6
Estimate 39 divided by 5
ummm.. i think its 7.8?
The value of the division of the number 39 by 5 is 7.8.
A mathematical procedure called division involves dividing a quantity or number into equal pieces or groups. It is used to calculate how many times one number (the divisor) may be subtracted from another (the dividend) in order to get an accurate answer or a quotient. It is the opposite operation of multiplication.
To estimate 39 divided by 5, we can use rounding to simplify the calculation.
Round 39 to the nearest multiple of 5. In this case, 39 is already a multiple of 5, so we don't need to round it.
Divide the rounded number by 5. Since 39 is already a multiple of 5, we can directly divide it by 5.
39 ÷ 5 = 7.8
So, an estimated value for 39 divided by 5 is 7.8.
