Answer:
36
Step-by-step explanation:
Width = x
Length = 4x
Perimeter = Width + Width + Length + Length (Because there are four sides; two sides are the widgth and two sides are the length)
30 (because 30 is given as the perimeter) = x + x + 4x + 4x
30 = 10x
x = 3
Width = 3
Length = 4(3) = 12
Area = Width * Length
Area = 3 * 12 = 36
The area of the rectangular sign is equal to 36 square inches, if its perimeter is 30 inches.
Let the length of the rectangular sign be L.Let the width of the rectangular sign be W.Given the following data:
Perimeter of rectangular sign = 30 inches.Translating the word problem into an algebraic equation, we have;
[tex]L = 4W[/tex]
Mathematically, the perimeter of a rectangle is given by the formula;
[tex]P = 2(L+W)\\\\30 = 2(4W + W)\\\\30 = 2(5W)\\\\30 = 10W\\\\W = \frac{30}{10}[/tex]
Width, W = 3 inches
For its length:
[tex]L = 4W\\\\L = 4(3)[/tex]
Length, L = 12 inches.
Now, we can determine the area of the rectangular sign by using the formula:
[tex]Area = LW\\\\Area = 12(3)[/tex]
Area = 36 square inches.
Therefore, the area of the rectangular sign is equal to 36 square inches.

Describe its parts. 9. The part of the expression that represents a quotient is. (Use the operation symbols in the math palette as needed. Do not simplify.)
Answer:
9. The part of the equation that represents a quoient is (10÷2) because inside the parentheses you solve the division equation and a quoitent is the answer to a division equation
10. The part of the expression that represents the product of two factors would be 6.7s because 6.7 is being multiplied by s, and a product is an answer to a multiplication problem
Step-by-step explanation:
9. The part of the equation that represents a quotient is (10÷2). 10. The part of the equation that represents the product of two elements is 6.7s.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
The expression is given in the question, as follows:
6.7s - (10÷2) +15
9. The part of the equation that represents a quotient is (10÷2) since the division equation is solved inside the parenthesis and a quotient is the answer to a division problem.

A chef at a restaurant uses 17 pounds of butter each day. About how many grams does the chef use each day?
answer
7711.07
Step-by-step explanation:
The chef uses 7,711.03 grams each day at a restaurant.
How to convert Pounds to Grams?The methodology to convert Pounds to Grams is relatively simple. To convert Pounds to Grams, you must multiply the unit by 453.59.
For example, if you have to convert 5 Pounds to Grams, you need to multiply 5 by 453.59.
A chef at a restaurant uses 17 pounds of butter each day.
We have to determine the number of grams the chef uses each day.
Since 1 pound (lb) is equal to 453.59 grams (g).
So 17 pounds = 453.59 × 17 = 7,711.03 grams
Thus, the chef uses 7,711.03 grams each day.

Four less than twice a number is fifty
Answer:
28
Step-by-step explanation:
50+4= 54
54/2=28
Answer:
2a - 4 = 50
Step-by-step explanation:
Less than means that you subtract 4.
Twice a number just means that you multiply a number by 2.
And we know that all of that equals 50.
If you want to solve it..
2a - 4 = 50
+4 +4
-----------------
2a = 54
Divide both sides by 2. 54/2 = 27

Answer:
a. m<CBA = m<DBA because of the definition of an angle bisector (angle bisector cuts the angle in half) We are also told that segment BD and Segment BC are congruent.
We don't know if segment AC and AD are congruent so we can't say those angles (the other two) are congruent.
b. point A and B will stay fixed because they are colinear to segment AB (on the same line)
c. Those two are needed because If those are true we can prove that they are congruent by SAS (Side Angle Side)
d. the reflection an prove that the lines and angles are congruent.

Twenty percent of all telephones of a certain type are submitted for service while under warranty. Of these, 70% can be repaired, whereas the other 30% must be replaced with new units. If a company purchases ten of these telephones, what is the probability that exactly two will end up being replaced under warranty?
Answer:
The required probability is 0.09875
Step-by-step explanation:
From the given information;
the probability of repairing the telephones = 0.70
the probability of the replaced = 0.30
Suppose we consider Mto denotes the telephone that is submitted for service while under warranty and must be replaced.
Then;
p = P(S) = P(replaced | submitted) P(submitted)
= 0.30 × 0.20
= 0.06
Now, the probability that exactly two will end up being replaced under warranty given that it assumes a binomial distribution where n = 10 and p = 0.06
[tex]P(X=2)=\bigg (^{10}_{2}\bigg) 0.06^2(1-0.06)^{10-2}[/tex]
[tex]P(X=2)=\dfrac{10!}{2!(10-2)!}\times 0.06^2\times (0.94)^{8}[/tex]

a. 0.156
b. 0.844
c. 0.357
d. 0.201
Answer:
The correct option is c.
Step-by-step explanation:
The percentage probability distribution is:
Size (X) Percentage
2 39.9
3 24.4
4 20.1
5 10.8
6 3.3
7 1.5
Total 100.0
Compute the probability that the size of the family is 4 or more as follows:
P (X ≥ 4) = P (X = 4) + P (X = 5) + P (X = 6) + P (X = 7)
= 0.201 + 0.108 + 0.033 + 0.015
= 0.357
Thus, the probability that the size of the family is 4 or more is 0.357.
The correct option is c.

7n + 5 =68.... how to solve this problem and show my work
Answer:
n=9
Step-by-step explanation:
7n+5=68 Subtract 5 on both sides.
-5 -5
7n=63 Divide both sides by 7.
/7 /7
n=9
Hope this helps! Have a nice day ^^
Answer:
n = 9
Step-by-step explanation:
1) Move similar terms to one side. Here we are moving the 5 over to the side with 68 by subtracting it. We also have to subtract 5 from the other side too (what you do to one side you must do to the other)
7n + 5 = 68
- 5 -5
7n = 63
2) Isolate the variable. We do this by dividing the 7 from 7n. We also have to divide 7 from other other side too.
7n = 63
/7 /7
n =9
A goat is tied to the corner of a rectangular shed in a large field full of grass. The rope is 2 yards long and a plane view (from above) of the shed and field is shown below. Use this information for Parts A and B below.
Part A: Calculate the area of grass that the goat can eat.
Part B: What length of rope would enable the goat to eat 30 square yards of grass? Show all your reasoning.
Answer:
9.42 yd²3.57 ydStep-by-step explanation:
Part AThe area of circle with radius of 2 yd (the length of the rope) is:
A = π*r² = 3.14*2² = 12.56 yd²Since 1/4 of the circle is occupied by the shed, the area of the grass is:
12.56*3/4 = 9.42 yd²Part BLet the area be 30 yd², finding the r as per above formula:
3/4*3.14*r² = 30r² = 30*4/3*3.14r² = 12.74r = √12.74r = 3.57 yd
