Answer:
12 inches
Step-by-step explanation:
A choir teacher is dividing 12 sopranos and 9 altos into singing groups. He wants each group to have the same combination of sopranos and altos, with no singers left over. What is the greatest number of groups he can make?
Answer:
3 groups
Step-by-step explanation:
Sopranos = 12
Altos = 9
Find the highest common factor of 12 and 9
12 = 1, 2, 3, 4, 6, 12
9 = 1, 3, 9
The highest common factor of 12 and 9 is 3
Therefore, the choir teacher can only have 3 groups
12 sopranos / 3 groups
= 4 sopranos per group
9 Altos / 3 groups
= 3 altos per group
Each of the 3 groups Will have 4 sopranos and 3 altos each
Last year, Goran opened an investment account with 5600. At the end of the year, the amount in the account had increased by 23.5% . How much is this increase in dollars? How much money was in his account at the end of last year?
Answer:
a) 1316 dollars
b) 6916 dollars
Step-by-step explanation:
Last year, Goran opened an investment account with 5600. At the end of the year, the amount in the account had increased by 23.5% .
a) How much is this increase in dollars?
The increase on dollars is calculated as:
5600 × 23.5%
= 1316 dollars
b) How much money was in his account at the end of last year ?
The amount of money in his account at the end of last year is calculated as:
Increase + Initial amount invested
=( 1316 + 5600) dollars
= 6916 dollars

Given:
A quadrilateral inscribed in a circle.
To find:
The value of x and y.
Solution:
If a quadrilateral inscribed in a circle, then it is known as cyclic quadrilateral and the opposite angles of a cyclic quadrilateral are supplementary angles, it means their sum is 180 degrees.
[tex]5x^\circ+110^\circ=180^\circ[/tex] [Supplementary angles]
[tex]5x^\circ=180^\circ -110^\circ[/tex]
[tex]x^\circ=\dfrac{70^\circ}{5}[/tex]
[tex]x^\circ=14^\circ[/tex]
The value of x is 14 degrees.
[tex]2y^\circ+104^\circ=180^\circ[/tex] [Supplementary angles]
[tex]2y^\circ=180^\circ -104^\circ[/tex]
[tex]y^\circ=\dfrac{76^\circ}{2}[/tex]
[tex]y^\circ=38^\circ[/tex]
Therefore, the value of x is 14 degrees and the value of y is 38 degrees.

Answer:
[tex]5\sqrt{3}[/tex]
Step-by-step explanation:
A triangle with angles of 30-60-90 will always have sides that measure in the following proportions:
The side opposite the 30* angle = a
The side opposite the 60* angle = [tex]a\sqrt{3}[/tex]
The side opposite the 90* angle = 2a
(I used "a" here because your question uses "x" and I don't want to confuse things, but usually people use "x" rather than "a")
They gave us that the hypotenuse (the side opposite the 90* angle) is 10, from there we can figure out the other sides:
Since the side opposite 90* is 2a, and 2a = 10, divide 10 by 2 and you get a = 5.
Once we know what "a" is, we can fill in the rest:
30* = 5
60* = [tex]5\sqrt{3}[/tex]
90* = 10

A skydiver jumps from a plane 10,000 feet above ground level. The height of the skydiver above the ground, in feet, can be modeled using the polynomial −32t2+10,000 in the absence of friction. Use the interactive below to calculate the average velocity over various intervals and to make observations about the relationship between average velocity and instantaneous velocity.
Answer:
Step-by-step explanation:
average velocity=distance/time= ending position−starting height ending time−starting time
How many times do the lines intersect? *
Y= - 4x +1
Y=7x + 2
Answer:
Once. The point of intersection is (-5/7, 3)
Step-by-step explanation:
Once. You have two straight lines here with different slopes, and neither is the negative reciprocal of the other. There is one solution to this system of linear equations.
Setting the two equations equal to each other, we get
y = -4 + 1 = 7x + 2, or
-3 = 7x + 2, or
7x = -5, or x = -5/7.
From the first equation and x = -5/7, we find y:
y = 7(-5/7) + 2, or y = -5 + 2, or y = 3.
The ONE solution is (-5/7, 3)

y = 2x+5 or -2x+y =5
Step-by-step explanation:
You can use the graph to help you find the solution. You are given your Y intercept as on of the points which is 5. Because you have that you can then count to were your next point is located or use the slope equation [tex]\frac{y2-y1}{x2-x1}[/tex], to find the slope.
A movie starts at 7:10 and ends at 9:03. How long does the movie last?
Answer:
1 hour and 53 minutes
Step-by-step explanation:
Let's start at 7:10.
7:10 - 8:10 is 1 hour.
8:10 - 9:00 is 50 more minutes.
Total so far is 1 hour 50 minutes.
9:00 - 9:03 is 3 more minutes.
Total would be 1 hour and 53 minutes
Hope this answer helped! :)
Answer:
1 hour and 53 minutes
Step-by-step explanation:
You just need to subtract the times form each other.
There are two ways to do this.
Subtract the number of minutes and convert into total hours and remainder minutes.
Or you can just do the simple way shown by the answer above.
I will show the subtracting minutes one since it can be a base for all .
First we find how many minutes are in 7 hours and 10 minutes, and nine hours and three minutes.
7 hours and ten minutes is 430 minutes. 9 hours and 3 minutes is 543 minutes.
543 - 430 is 113.
Then you divide, we are using the remainder type division.
113/60(60 minutes in one hour)
60 goes into 113 one time and leaves 53.
Therefore, it takes 1 hour and 53 minutes.

Let (10, 24) be a point on the terminal side of an angle θ in standard position. evaluate the six trigonometric function of θ.
Sin,cos,tan,csc, sec, cot??
Step-by-step explanation:
x=10
y=24
r=√10²+24²=√100+576=√676=26
sin = y/r = 24/26
cos = x/r =10/26
tan=y/x = 24/10
csc = r/y=26/24
sec= r/x = 26/10
tan = x/y = 10/24
87=x+4 in exponential form
Answer:
87=x + 4 x=83
Step-by-step explanation:
87= x + 4
Switch sides
x + 4 = 87
Subtract 4 from both sides
x + 4-4 = 87-4
Simplify
x = 83

The function shown has an endpoint discontinuity. Which statement describes the one-sided limits at the discontinuity?
Answer:
b
Step-by-step explanation:
edg 2020
'Function' is described as 'a relation in which each component of the domain is related to precisely one component of the codomain.'
B). The statement second "Limit of f(x) = - 2 as x approaches 1 minus. Limit of f(x) DNE as x approaches 1+" correctly elaborates the single-sided limits when the end-point dislocates.
'End-point discontinuity' is described as a function that carries a shut endpoint at its interlude.While 'one-sided limits' are described as the limit(any out of the two) belonging to a function (x) when x advances towards either side(left or right). Thus, it limits x and the rest values remain the same. In the given function, the one-sided limit of the function(x) equals to -2 when it advances towards -1 and DNE when it advances towards 1+.Thus, option B is the correct answer.
