Answer:
x = 38
∠P = 26º
Step-by-step explanation:
The sum of the angle in a triangle is 180
x + (x + 78) + (x - 12) = 180
Combine like terms
3x + 66 = 180
Subtract 66 from both sides
3x = 114
Divide both sides by 3
x = 38
-----------------------
∠P = x - 12
∠P = 38 - 12
∠P = 26º
Answer:
Step-by-step explanation:
(x+78)+(x-12)+x=180
3x+66=180
3x=114
x=38
P=26

There are four cards numbered 1 through 4. The number 2 card is chosen randomly and not replaced. Find the probability of choosing a second card that is the number 3.
Answer:
1/3
Step-by-step explanation:
since number 2 card was not replaced, we have;
probability of picking a second card, 3;
let S be number of sample space
n(S)= 4
n(3)= 1
Pr(3/2)= 1/3
(because since one was already chosen and n, the sample space would reduce)

Step-by-step explanation:
A college professor hands out a list of 10 questions, 5 of which will appear on the final exam for the course. One of the students taking the course is pressed for time and can prepare for MATH 270 Assignment 2 W. Li 2 only 7 of the 10 questions on the list. Suppose the professor chooses the 5 questions at random from the 10. a) What is the probability that the student will be prepared for all 5 questions that appear on the final examination
Answer:
21 / 252
Step-by-step explanation:
Recall : nCr = n! ÷ (n-r)!r!
The total possible outcome ; 5 questions out of 10
10C5 = 10! ÷ 5!5! = (10*9*8*7*6)÷(5*4*3*2*1) = 252
Required outcome :
All 5 questions set being from the 7 questions covered and 0 from the 3 left uncovered
7C5 * 3C0
7C5 = 7! ÷ 2!5! = (7*6) ÷ (2*1) = 21
3C0 = 3! ÷ 3!0! = 1
Probability = required outcome / Total possible outcomes
P(All 5 questions prepared for appears) :
[7C5 * 3C0] ÷ 10C5
(21 * 1) / 252
= 21 / 252
Grace has $15 in her bank account. She starts
saving $5 each week. Jose has $5 in his account
and is saving $10 each week. What is the slope of the line that represents Grace's bank account?
Answer:
[tex]\frac{5}{1}[/tex] or 5
Step-by-step explanation:
Using the data provided we would create the following equation to calculate Grace's bank account using the variable x to represent the number of weeks.
f(x) = 5x + 15
The slope of a function in such a function would be the value of that is being multiplied by x. The numerator would be the numberof units it is rising in a graph while the denominator represents the number of units it is moving to the right. Since in this scenario, the number is a whole number (5) the denominator is automatically 1. Meaning that the slope is 5 units up for every 1 unit to the right.

??????????????????????
Answer:
Multiply by -2
Step-by-step explanation:
Additive inverse essentially means the counterpart that negates a number. Then, elimination can be used. In this case, the easiest change would be with the terms -4y in the first equation, and -2y in the second equation, since 2 is a factor of 4. So,
3x - 4y = -5
5x - 2y = -6
The goal here is to cancel out the -4y.
(5x - 2y)(-2) = (-6)(-2)
-10 + 4y = 12
3x - 4y = -5
Now it works.
Angel says that raising fraction to the power of -1 is the same as finding the reciprocal of the fraction do you agree
Yes, raising fraction as the power to the integer number is same as calculating the reciprocal of the fraction.
According to the question, the simplification method for the raising fraction as the power to the integer number(-1) is same as calculating the reciprocal of the fraction.
Raising power means multiplying that number that many times to get the answer.
What is simplification in fraction?
The word simplification in fraction is the procedure in which complicated expression can be written in a simpler form to make the calculation easy. This method is used to calculated the answers for the unknown quantity.

“The child’s tickets cost $4 each and the adult’s ticket cost $8 each. Write an equation that would represent the total cost, T, of purchasing a child’s tickets, c, and an adult’s tickets, a.”
Answer:
cxa=t cause you are mulltipling to find the total cost
Answer:
Step-by-step explanation:
A child´s ticket costs $4 and adults ticket costs $8. If we want one of each we need to add both numbers together, 4 plus 8 equals 12. The total cost of a child ticket and an adult ticket is $12.
The questions asked to write an equation; the equation would be:
C+A=T it could also be written as A+C=T, T=A+C or T=C+A.

The length of a side and the corresponding height of a triangle are (x+3) cm and (2x-5) cm respectively. Given that thr area of the triangle is 20 cm^2, find the value of x.
Answer: 5
Step-by-step explanation:
Given
The length of a side is [tex]x+3\ cm[/tex]
The height of a triangle is [tex]2x-5\ cm[/tex]
Area of triangle is [tex]20\ cm^2[/tex]
Area of triangle is given by
[tex]\Rightarrow A=\dfrac{1}{2}\times \text{base}\times \text{height}[/tex]
[tex]\Rightarrow A=\dfrac{1}{2}\times (x+3)\times (2x-5)\\\\\Rightarrow 40=(x+3)\times (2x-5)\\\Rightarrow 2x^2+x-55=0\\\\\Rightarrow x=\dfrac{-1\pm \sqrt{1^2-4(2)(-55)}}{2(2)}\\\\\Rightarrow x=\dfrac{-1\pm 21}{4}\\\\\Rightarrow x=-5.5,5[/tex]
Neglecting negative value
Therefore, the value of x is 5.

Find the rate percent per annum at which birr 380 earns birr 128.25 in 7 years and 6 months?
Answer:
A = $4,035.13
Step-by-step explanation:
Given: 380 earns, 128.25 in 7 years and 6 months
To find: The rate percent per annum
Formula: [tex]A = P(1 + rt)[/tex]
Solution: I = A - P = $3,655.13
Equation:
A = P(1 + rt)
First, converting R percent to r a decimal
r = R/100 = 128.25%/100 = 1.2825 per year.
Solving our equation:
A = 380(1 + (1.2825 × 7.5)) = 4035.125
A = $4,035.13
The total amount accrued, principal plus interest, from simple interest on a principal of $380.00 at a rate of 128.25% per year for 7.5 years is $4,035.13.

1200 bricks each of 0.075m3 volume are required to construct a wall of length 25m and height 9m. Find the breadth of the wall.
Here's the solution,
Volume of wall :
=》total bricks × volume of each brick
=》1200 × 0.075 m³
=》90 m³
volume of wall :
=》lenght × width × height
=》25 × 9 × width
=》225 × width
now, by equating the volumes, we get
( since they are volume of same wall )
=》225 × width = 90
=》width = 90 ÷ 225
=》width of wall = 0.4 m

Answer: 37, [tex]\frac{x+2}{7}[/tex]
Step-by-step explanation:
Given
[tex]f(x)=7x-2\\g(x)=x^2+1\\h(x)=3x[/tex]
now,
[tex]g(h(x))=(3x)^2+1\\g(h(x))=9x^2+1[/tex]
