Solve for X. Plz I can't figure it outtt!
9514 1404 393
Answer:
x = 40
Step-by-step explanation:
The angle bisector divides corresponding sides proportionally.
x/16 = 25/10
x = 16(25/10) . . . . . multiply by 16
x = 40
The scale on a map Is 1 Inch to 3 mlles. If the distance between two points is 6 Inches, what proportion should you use
to find the actual distance?
3 miles/1 inch=6 inches/ x x/1 inches = 6 inches/3 miles x/1 inch= 6 inches/3 miles 1inch/3 miles= 6 inches/x
What is the measure of x?
30°
60°
90°
120°
Answer:
the measurement of x is 30 degrees
A line passes through the point (-1, -2) and has a slope of 5.
Write an equation in slope-intercept form for this line.
Answer:
[tex]y=5x+3[/tex]
Step-by-step explanation:
Slope-intercept form: [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the value of y when the line crosses the y-axis)
1) Plug the given slope 5 into the equation
[tex]y=mx+b\\y=5x+b[/tex]
2) Find the y-intercept [tex]b[/tex] by plugging in the point (-1,-2)
[tex]y=5x+b\\-2=5(-1)+b\\-2=-5+b[/tex]
Add 5 to both sides
[tex]-2+5=-5+b+5\\3=b[/tex]
3) Plug the y-intercept back into the equation
[tex]y=5x+3[/tex]
I hope this helps!
A teacher gave a 3-question multiple choice quiz. Each question had 4 choices to select from. If the a student completely guessed on every problem, what is the probability that they will have 2 or less correct answers?
Answer:
0.9844
Step-by-step explanation:
This is a binomial probability problem.
Probability of getting a correct answer: p = 1/4
Probability of getting an incorrect answer: q = 3/4
Number of questions; n = 3
Thus;
probability of 2 or less correct answers is; P(x ≤ 2) = P(X = 2) + P(X = 1) + P(X = 0)
From binomial probability the formula is;
P(X = x) = C(n, x) × p^(x) × q^(n - x)
P(X = 2) = C(3, 2) × (¼)² × (¾)¹
P(X = 2) = 3 × 0.0625 × 0.75
P(X = 2) = 0.1406
P(X = 1) = C(3, 1) × (¼)¹ × (¾)²
P(X = 1) = 3 × 0.25 × 0.5625
P(X = 1) = 0.4219
P(X = 0) = C(3, 0) × (¼)^(0) × (¾)³
P(X = 0) = 0.4219
P(x ≤ 2) = 0.1406 + 0.4219 + 0.4219
P(x ≤ 2) = 0.9844

Answer:
x₂ = - 3
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to [tex]\frac{5}{6}[/tex]
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (9, 9) and (x₂, y₂ ) = (x₂, - 1)
m = [tex]\frac{-1-9}{x_{2}-9 }[/tex] , that is
[tex]\frac{-10}{x_{2}-9 }[/tex] = [tex]\frac{5}{6}[/tex] ( cross- multiply )
5(x₂ - 9) = - 60 ( divide both sides by 5 )
x₂ - 9 = - 12 ( add 9 to both sides )
x₂ = - 3

As a retiring employee, Khadijah receives 5% of her average teaching salary for the last five
years she worked. She receives this salary for every year of employment with the company.
Khadijah plans on retiring after 15 years with the school system and then start her own
Corporation. Her salaries for the last five years are $65,000, $70,000, $82,000, $83,000, and
$88,500. Calculate Khadijah's total retirement salary for 15 years.
Answer:
Step-by-step explanation:
Average salary = ($65,000 + $72,000 + ... + 88,500 )/5 = $77,100
5% of $77,100 = $3,855
15 years * $3,855/year = $57,825
If two sweaters and four shirts cost $150, and four sweaters and three shirts cost $200, find the price of each shirt and each sweater.
Answer:
shirt = $20
sweater = $35
Step-by-step explanation:
This question would be solved using simultaneous equation
Let the price of sweater be represented by a
Let the price of shirt be represented by b
The following equations can be derived from the question
2a + 4b = 150 equation 1
4a + 3b = 200 equation 2
Multiply equation 1 by 2
4a + 8b = 300 equation 3
Subtract equation 2 from 3
5b = 100
divide both sides of the equation by 5
b = 20
substitute for b in equation 1
2a + 4(20) = 150
2a + 80 = 150
collect like terms
2a = 150 - 80
2a = 70
divide both sides by 2
a = 35
Price of sweater = $35
Price of shirt = $20

URGENT HELP
Answer:
105
Step-by-step explanation:
Hello There!
(Let x = angle T)
if you didn't know an exterior angle of a triangle is equal to its two opposite interior angles
So basically
155 (being the exterior angle) is equal to 50 + x (being the opposite interior angles)
so x = 155 - 50
155 - 50 = 105
so we can conclude that x (angle T) equals 105
Answer:
105 degrees
Step-by-step explanation:
The angle measure of the exterior angle is equal to the sum of the two nonadjacent interior angles (angle V and angle T).
155 - 50 = 105

At Maddison high school each student studies one foreign language is 3/5 take Spanish and one-fourth of the remaining take german what percent takes frnechan how
Answer:
Step-by-step explanation:
3/5 = 0.6
1 - 0.6 = 0.4 students left
Multiply the amount of students remaining by the fractional amount that take German
0.4 x 1/4 = 0.1
1 - 0.6 - 0.1 = 0.3
0.3 x 100 = 30%
Therefore 30% of students take French
