Step-by-step explanation:
Quick Solve!
Side #1:
1 yard = 36 inches4 * 36 = 144 inches1 foot = 12 inches2 * 12 = 24 inches144 inches + 24 inches + 7 inches = 175 inches
Side #2:
2 yards = 2 * 36 = 72 inches1 foot = 12 inches + the 6 inches = 18 inches72 inches + 18 inches = 90 inches72 inches + 18 inches = 90 inches + 6 inches = 96 inches
Conclusion:
175 inches + 96 inches = 271 inches
Answer:
⇒ 7 yds 1 ft 1 inch
Answer:
7 yards 1 foot 1 inch
Step-by-step explanation:
Adding both of them together, you get:
6 yards 3 feet 13 inches
Since 1 foot = 12 inches, and 13 inches exceeds that, add a foot to the previous 3 feet and subtract 12 from the 13 inches
Therefore: 6 yards 4 feet 1 inch
Since 1 yard = 3 feet, and 4 feet exceeds that, add a yard to the previous 6 yards and subtract 3 feet from the remaining 4 feet
Hence:
7 yards 1 foot 1 inch
Part of the proceeds from a garage sale was $540 worth of $5 and $20 bills If there were 3 more bills $5 bills than $20 bills, find the number of each denomination.
An equation is formed when two equal expressions. There are 21 $20 bills and 24 $5 bills.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the number of $5 bills be x, while the number of $20 bills be y.
Given there were 3 more $5 bills than $20 bills. Therefore, this can be represented as
x = y + 3
Also, The total worth of the dominations is $540. Therefore, we can write,
5x + 20y = 540
Substitute the value of x form the first equation,
5x + 20y = 540
5(y+3) + 20y = 540
5y + 15 + 20y = 540
25y = 525
y = 21
Substitute the value of y in the first equation,
x = 21 + 3
x = 24
Hence, there are 21 $20 bills, and 24 $5 bills.

A 210-N mass is suspended from a horizontal beam by two cables that make angles of 29 degrees and 53 degrees with the beam. Find, using vectors, the tension in the cables.
The tension in both cables are calculated as; T₁ = 127.63 N and T₂ = 185.48 N
Resolving forces in the y direction gives us;
T₁ sin 29° + T₂ sin 53° = 210 ------(eq 1)
Resolving forces in the horizontal direction gives;
T₁ cos 29° = T₂ cos 53° ----(eq 2)
T₁ = T₂ cos 53°/cos 29°
Thus;
(T₂ cos 53°/cos 29°)sin 29° + T₂ sin 53° = 210
0.3336T₂ + 0.7986T₂ = 210
T₂ = 210/1.1322
T₂ = 185.48 N

a−(−3.75)=6.11
What is a?
Answer:
a = 2.36
Step-by-step explanation:
a-(-3.75)=6.11
The negative 3.75 is being subtracted from the 'a'. A negative number being subtracted from another number makes it positive. So, 3.75 is actually being added to 'a' which is equal to 6.11
I re-wrote the question as:
a + 3.75 = 6.11
Subtract 3.75 from both sides to leave 'a' by itself
a + 3.75 = 6.11
-3.75 -3.75
a = 2.36
In the figure below, j || m. Find the values of x and y.
X and 73 are same-side interior angles, which are supplementary (they add up to 180).
x + 73 = 180
x = 107
X and (6y - 79) are vertical angles, which are congruent (have the same measure/value.
x = 6y - 79
107 = 6y - 79
6y = 186

What are the solutions of the equation (x 2)2 – 2(x 2) – 15 = 0? use u substitution to solve.
The solution of the equation is x=3 or x=-5.
Given that the equation is (x+2)²-2(x-+2)-15=0 and use u substitution method to solve.
Let's assume that the (x+2)=u.
The given equation is rewritten as u²-2u-15=0.
Factorize the quadratic equation by adding or subtracting two number that gives the sum of -2u and product 15u² as
u²-5u+3u-15=0
u(u-5)+3(u-5)=0
Taking out (u-5) as common and get
(u-5)(u+3)=0
Compare each equation with 0 and get
u-5=0 or u+3=0
u=5 or u=-3
Performing back substitution by substituting the values of u in x+2
when u=5 then x is
x+2=5
x=3
And when u=-3 then x is
x+2=-3
x=-5
Hence, the solutions of the (x+2)²-2(x-+2)-15=0 is x=3 and x=-5.

What is the experimental probability that a coin toss results in one head and one tail showing?
Compare the theoretical probabilities to your experimental probabilities. Why might there be a difference?
The theoretical probability of getting two tails on two coin tosses is 0.25.
How to calculate the probability?The theoretical probability is the ratio of the number of favorable outcomes to the number of possible outcomes. Given a coin is tossed twice.
We have to find the theoretical probability of tossing two tails. The probability of getting tails on the toss of a coin is 1/2 0r 0.5.
