Justin worked 12 hours and 4 minutes on Saturday and 13 hours and 41 minutes on Sunday. How many hours did Justin work this weekend?
Answer:
Justin worked 25 hours and 45 minutes.
25 3/4 hours total
First add the hours together.
12 + 13 = 25
Then add the minutes together.
4 + 41 = 45
So 25 hours and 45 minutes
or
25 3/4 hours
45 minutes is also 3/4 of an hour

| 4x-13 | = 5x+4
Solve
Answer:
x = 1
Step-by-step explanation:
The absolute value always gives a positive value. However, the expression inside can be positive or negative , so
4x - 13 = 5x + 4 ( subtract 4x from both sides )
- 13 = x + 4 ( subtract 4 from both sides )
- 17 = x
OR
- (4x - 13) = 5x + 4 , simplify left side
- 4x + 13 = 5x + 4 ( subtract 5x from both sides )
- 9x + 13 = 4 ( subtract 13 from both sides )
- 9x = - 9 ( divide both sides by - 9 )
x = 1
As a check
Substitute these values into the equation and if both sides are equal then they are solutions.
x = - 17
left side = | 4(- 17) - 13 | = | - 68 - 13 | = | - 81 | = 81
right side = 5(- 17) + 4 = - 85 + 4 = - 81 ≠ 81
Then x = - 17 is an extraneous solution
x = 1
left side = | 4(1) - 13 | = | 4 - 13 | = | - 9 | = 9
right side = 5(1) + 4 = 5 + 4 = 9
Then solution is x = 1
Find the vertex of a quadratic function written in standard form.
f(x) = 3x2 + 18x + 32
PLS HELP!!
Answer:
our vertex for f(x) = 3x² + 18x + 32 = (-3, 5 )
Step-by-step explanation:
let me write the standard form of a quadratic equation
[tex]a {x}^{2} + bx + c[/tex]
Now let me rewrite the original equation
[tex]3 {x}^{2} + 18x + 32[/tex]
Now we use this simple formula to find the vertex (h, k)
[tex]x = h = - \frac{b}{2a} \\ = - \frac{18}{2(3)} = - \frac{18}{6} = - 3 \\ h = - 3[/tex]
substitute -3 for x back into our original equation to solve for y our k value of our vertex
[tex]y = 3 ({ - 3})^{2} + 18( - 3) + 32 \\ = 3(9) - 54 + 32 \\ = 27 + 32 - 54 \\ = 59 - 54 \\ k = 5[/tex]
our vertex for f(x) = 3x² + 18x + 32 = (-3, 5 )

Please help!!!!!!! I only have 20 minutes left!!
Step-by-step explanation:
You need to find the total number of students the pie chart will represent:
17 + 35 + 38 = 90
So you know, 360° represents 90 people
You can then find out the angle for each person: 360 ÷ 90 = 4
Each person is 4°
a)
1. 17 people took French so you would do 4° × 17 = 68°
2. 35 people took German so you would do 4° × 35 = 140°
3. 38 people took Italian so you would do 4° × 38 = 152°
b)
17 out of 90 people chose french so the probability would be 17/90
by what percentage did the high temperature increase from friday to saturday ? round ur answer
Answer:
Step-by-step explanation:
First, you must find the actual decrease in temperature.
Decrease = Yesterday's temperature - Today's temperature
Decrease = 80 - 75
Decrease = 5 degrees
Now, find the percentage decrease.
% Decrease = Actual decrease / Yesterday's temperature x 100
% Decrease = 5/80 x 100
% Decrease = 0.0625 x 100
% Decrease = 6.25 %
So, the percent decrease in high temperature from yesterday to today is 6.25%
Which statement is true? 13/14=169/182 13/14<169/182 13/14>169/182
pls help me
Answer: 13/14 = 169/182
Step-by-step explanation:
If you do 13 x 182 = 2,366
And then do 14 x 169 = 2,366
Making both sides equal if you multiple the numerator by denominator using cross multiplication
The fraction number 13/14 is equal to the fraction number 169/182. Then the true statement is A.
What is Algebra?Algebra is the study of mathematical symbols, while logic is the manipulation of those icons.
The product is another name for it. If the same thing, n, is delivered to m different people, we merely multiply them.
The fraction number is given below.
⇒ 13/14 and 169/182
Multiply the fraction number 13/14 by 13 in numerator and denominator. Then the expression is written as,
⇒ (13 x 13)/(14 x 13)
⇒ 196 / 182
The fraction number 13/14 is equal to the fraction number 169/182. Then the true statement is A.

z-16z=15 what is z please
Answer:
z is equal to -0.88235294117
Step-by-step explanation:
so you first need to do is z minus 16z which is -17z.
you now have -17z is 15
you need to divide each side by -17z
so -17z divided by -17 is 1 z
and 15 divided by -17 is -0.88235294117
so z is equal to -0.88235294117
Hey there!
z - 16z = 15
-15z = 15
DIVIDE -15 to BOTH SIDES
-15z/-15 = 15/-15
CANCEL out: -15/-15 because that gives you 1
KEEP: 15/-15 because gives you the result of the z-value
SIMPLIFY IT
z = -1
Answer: z = -1

Find the 21st term of the arithmetic sequence an=9+3(n-4) a21=
Answer:
120
Step-by-step explanation:
Given arithmetic sequence
3,5,7,9,.........,21
The first term a=3 & a common difference d=5−3=7−5=⋯=2
If there are n number of terms in the above A.P. then last term l=21 will be the nth term given as
l=a+(n−1)d
21=3+(n−1)2
n=10
hence the sum of given arithmetic progression (A.P.) up to 10 terms is given general formula

The fire department is setting off fireworks. They notice that the casings of the fireworks hit the ground 78 seconds after the firework was launched. The firework exploded at a maximum height of 760.5 meters.
Identify how you see the x- and y-intercepts and vertex in the table, graph, and equation. (Hint: You may want to rewrite the equation in equivalent forms.)
The firework is an illustration of the equation of a parabola.
The x-intercepts are 0 and 78, the y-intercept is 0, and the vertex is (39,760.5)
The casings hit the ground after 78 seconds.
This means that, a point on the graph is:
[tex]\mathbf{(x,y) = (78,0)}[/tex]
The firework exploded at a maximum of 760.5.
This means that, the vertex is:
[tex]\mathbf{(h,k) = (39,760.5)}[/tex]
The equation of a parabola is:
[tex]\mathbf{y = a(x - h)^2 + k}[/tex]
So, we have:
[tex]\mathbf{0 = a(78 - 39)^2 + 760.5}[/tex]
[tex]\mathbf{0 = a(39)^2 + 760.5}[/tex]
Subtract 760.5 from both sides
[tex]\mathbf{a(39)^2 =- 760.5}[/tex]
[tex]\mathbf{1521a =- 760.5}[/tex]
Solve for a
[tex]\mathbf{a =- \frac{760.5}{1521}}[/tex]
[tex]\mathbf{a =- 0.5}[/tex]
Substitute [tex]\mathbf{a =- 0.5}[/tex] and [tex]\mathbf{(h,k) = (39,760.5)}[/tex] in [tex]\mathbf{y = a(x - h)^2 + k}[/tex]
[tex]\mathbf{y = -0.5(x - 39)^2 + 760.5}[/tex]
See attachment for the graph of [tex]\mathbf{y = -0.5(x - 39)^2 + 760.5}[/tex].
From the graph:
The x and y intercepts are the points where the graph crosses the x and y axes. The vertex is the maximum point on the graphFrom the equation:
Set x to 0, to calculate the value of y for the y-interceptSet y to 0, to calculate the value of x for the x-intercept.The vertex is represented as: (h,k)Hence, the x-intercepts are 0 and 78, the y-intercept is 0, and the vertex is (39,760.5)

Ray GI bisects ∠DGH so that m∠DGI is 3x-9 and m∠IGH is 2x + 21. Find the m< DGI.
Answer:
[tex]3x - 9 = 2x + 21 \\ 3x - 2x - 9 = 2x - 2x + 21 \\ x - 9 = 21 \\ x - 9 + 9 = 21 + 9 \\ x = 30[/tex]
m<DGI = 80°
[tex]3x - 9 = \\ 3(30) - 9 = \\ 90 - 9 = 81[/tex]
The measure of angle ∠DGI can be obtained by finding the solution of the equation as 81°.
What is a linear equation?A linear equation in two variable has the general form as y = ax + by + c, where a, b and c are integers and a, b ≠ 0.
It can be represented as a straight line on a graph.
The ray GI bisects ∠DGH.
It implies that the new angles are equal in measurement.
⇒ m∠DGI = m∠IGH
⇒ 3x - 9 = 2x + 21
⇒ x = 30
Then, in order to calculate m∠DGI, plug x = 30 in 3x - 9 as,
3 × 30 - 9 = 81
Hence, the measure of angle ∠DGI is given as 81°.
