Answer:
x=10°
Step-by-step explanation:
(5x+7)°+(4x+16)°+(5x+17)°=180° (a triangle contains 180°)
5x+7+4x+16+5x+17=180
14x+40=180
14x=180-40
14x=140
x=140/14
x=10
x=10°
note:to avoid writing ° always. I made it implicit.

What’s the equation.?
Answer:
See below
Step-by-step explanation:
You know that he spent 1/3 of his earnings, and then 1/4. After this, he has $28.90. You can write the equation like this:
1/4(x * 1/3) = $28.90.
If you need to solve it:
1/4 * 1/3x = 28.90
1/12x = 28.90
x = 346.80

Answer:
The slope from point (4,7) and (7,-2) is (9,-3)
Step-by-step explanation:
If you plot both points on a graph and go from the (7,-2) one to the (4,7) you would go up 9 and to the left 3 which is why it is negative. It is rise over run

Celeste married with 4 withholding allowances she earned 1,298 each week find her withholding tax.
Use table(pic)
9514 1404 393
Answer:
$82.28
Step-by-step explanation:
Being married puts Celeste on the right half of the table. Four allowances put her in the 5th section down, where 4 is in the left-most column. Her weekly wage of 1298 puts her wage between 923.30 and 2068.20, so on the second line in that section.
The table tells you to subtract $612.37 from Celeste's weekly wage, then multiply the result by 12% to find her withholding. Doing that, we find the withholding to be ...
(1298.00 -612.37) × 0.12 = $82.28 . . . . rounded up to the nearest cent
The withholding tax applicable to Celeste's earnings is $82.28.
Find the 5th term of the
sequence: 2, -6, 18, -54...
Answer:
162 5th term
Step-by-step explanation:
Answer:
5th term =162
Step-by-step explanation:
It is a geometric progression whose nth term = ar^n-1
Where a = 1st term =2
r=ratio of two term= -6/2=-3
n =nth term
So 5th term= 2x-3^5-1
=2x-3^4
=2x81=162 answer

∠ and ∠ are supplementary angles. If ∠ = (2 − 30)° and ∠ = 4, find the measure of the larger angle
Answer:
We get ∠A =40° and ∠B = 140° and ∠B = 140° is measure of larger angle
Step-by-step explanation:
we have ∠A = (2x − 30)° and ∠B = 4x, and we need to find measure of larger angle. And ∠A and ∠A are supplementary angles.
If the angles are supplementary there sum is equal to 180° i.e ∠A + ∠B = 180°
So, First we have to find the value of x. and then we can determine larger angle.
We know: ∠A + ∠B = 180
2x-30+4x=180
6x-30=180
6x=180+30
6x=210
x=210/6
x=35
So, value of x is x=35
Now finding ∠A and ∠B
∠A = (2x − 30)°
∠A = (2(35) − 30)°
∠A = (70 − 30)°
∠A =40°
and ∠B = 4x
∠B = 4(35)
∠B = 140°
So, we get ∠A =40° and ∠B = 140° and ∠B = 140° is measure of larger angle

Una autopista atraviesa un cerro mediante un túnel que tiene forma de arco parabólico, tiene 4 metros de altura ¿Cuál es la altura máxima que puede tener un camión de transporte que tiene 2 metros de ancho para pasar sin atorarse?
Answer:
supongo que < 3m
Step-by-step explanation:
el túnel tiene forma de arco parabólico, pero no aclara qué coeficiente tiene el término [tex]x^{2}[/tex], ej: si es -[tex]x^{2}[/tex], ó -0.5 [tex]x^{2}[/tex], ó -0.1 [tex]x^{2}[/tex], ...
Suponiendo que tuviese coeficiente -1, entonces la ecuación del puente es:
f(x) = -[tex]x^{2}[/tex] + 4
Tomamos el valor de f(x=1) = f(x=-1), porque suponiendo que el camión va por el centro del túnel, y teniendo 2m de ancho, queda 1m hacia cada lado:
f(x=1) = f(x=-1) = 3
Con lo cual si el camión tiene 3m de alto choca con la curva parabólica que forma el túnel.
Slope intercept equation
What is the equation of the line that passes through the point (-4,-4) and has a
slope of 5/4?
Answer:
The answer is y= 5/4x+1
Step-by-step explanation:
y=mx+b
-4=5/4(-4)+b
-4=-5+b
+5 +5
1=b
So the equation of the line that passes through the point (-4,-4) and has a slope of 5/4 is y=5/4x+1 .
There are 21 students in a class. The median age of the students is 23. The oldest student is 29.
Based on this information, what is the truthfulness of each statement in the table? Select the phrase that best describes each statement.
Statement
Truthfulness
At least one student is 23. Must be true could be true cannot be true
Some students are younger than 15. Must be true could be true cannot be true
Answer:
1) At least one (the 11th) student is 23 (years old), Must be true
2) Some students are younger than 15 Could be true
Step-by-step explanation:
1) The given parameters are;
The number of student in the class = 21
The median age of the student = 23
The age of the oldest student = 29
Therefore, given that the median age = The age of the (n + 1)/2 th student
Where;
n = The number of student in the class = 21
∴ The median age = The age of the (21 + 1)/2 th = 11 th student, when the age of the students are arranged in increasing order, therefore, we have;
At least one (the 11th) student is 23 (years old), Must be true
2) Given that there are 10 students with ages equal to or lower than the median age, and the difference between the median age and the age of the oldest student = 29 - 23 = 6 years, we have;
Some students are younger than 15 Could be true
