Answer:
2s = 16
Step-by-step explanation:
In the choir, there are 16 altos and s sopranos.
Let the number of altos be a.
=> a = 16
There are twice as many sopranos as altos.This means that:
a = 2s
Since the number of altos, a, is 16, the equation that represents this situation is:
2s = 16
An equation representing the number of sopranos in a choir, given the number of altos is s = 2 x 16, which simplifies to s = 32.
The question asks us to write an equation to represent the number of sopranos in a choir based on the number of altos. Given that there are 16 altos and the number of sopranos is twice as many, we can represent the number of sopranos as s. The relationship between the altos and sopranos can be expressed mathematically as s = 2 × 16. Therefore, the equation that represents this situation is s = 32, where s stands for the number of sopranos in the choir.

Examine the system of equations. y = 2x – 3, y = –3 Which statement about the system of linear equations is true?
(A) The lines have different slopes.
(B) There is no solution to the system.
(C) The lines have the same slope, but different y-intercepts.
(D) The solution is (–3, –9).
Answer: A
Step-by-step explanation:
For a system of equations to have no real solution, the lines of the equations must be parallel to each other. The correct option is A the lines have different slopes.
What is the System of equations?Inconsistent System
For a system of equations to have no real solution, the lines of the equations must be parallel to each other.
Consistent System;
For a system of the equation to be a Dependent Consistent System, the system should have multiple solutions for which the lines of the equation must be coinciding.
For a system of the equation to be an Independent Consistent System, the system should have one unique solution for which the lines of the equation must intersect at a particular.
If the two of the given system of equations are plotted on the graph, y = 2x – 3, y = –3
Then it can be seen that the two lines have different slopes. Therefore, the correct option is A.

The area of the figure is ____ square units
Answer:
80 units
Step-by-step explanation:
Start with the rectangle of 8×6 which is 48.
Then start with a base, 2×6=12 and add 4, 2 per triangle. One base equals 16 and because it's 2 bases multiply by 2 equals 32.
32+48=80
The answer would be 80.

BC=
im not sure on how i am supposed to do this
Answer:
BC=15.01
Step-by-step explanation:
Line segment BC can also be represented by '?'. To solve for BC, find the value of '?'
Use the tangent ratio:
[tex]tangentX=\frac{opposite}{adjacent}[/tex]
Because you need the value opposite the given angle and you are given the length of the side adjacent the given angle (hypotenuse does not count as the adjacent side, EVER (btw)). Let 65° be X and let x replace'?'.Insert the appropriate values:
[tex]tan65=\frac{x}{7}[/tex]
Solve by isolating x. Multiply 7 to both sides:
[tex]7*(tan65)=7*(\frac{x}{7})\\\\7*tan65=x\\\\x=7*tan65[/tex]
Insert this equation into a calculator:
[tex]x=15.0115...[/tex]
Round to the nearest hundredth:
[tex]x=15.01[/tex]
So, BC is 15.01

Melissa has $1,000.00 to invest for 5 years. She can choose either simple interest at 6.4% interest, or compound interest at 12.8% interest, compounded annually.
Which is the better investment?
A. A compound interest investment would be better, because Melissa would earn $826.19 in compound interest.
B. A simple interest investment would be better, because Melissa would earn $826.19 in simple interest.
C. A simple interest investment would be better, because Melissa would earn $320.00 in simple interest.
D. A compound interest investment would be better, because Melissa would earn $320.00 in compound interest.

In circle P, the measure of arc BDC is 260, what is the measure of angle 1?
A. 100
B. 60
C. 50
D. 80
Answer:
C. 50 deg
Step-by-step explanation:
m(arc)BDC = 260 deg
Since a full circle has an arc measure of 360 deg, we can find the measure of arc BC.
m(arc)BC = 360 deg - 260 deg = 100 deg
Angle 1 is formed by a tangent to the circle and a chord of the circle and has a vertex on the circle. Its measure is half the measure of the intercepted arc.
m<1 = (1/2)m(arc)BC = (1/2) * 100 deg = 50 deg
Answer: C. 50 deg

Can someone please find the volume of this shape and show work for how you did it??
Answer:
[tex]221.4m^{3}[/tex]
Step-by-step explanation:
To work out the volume of this shape you will first need to work out the area of the triangle. To work out the area of the triangle you would multiply the base of 12 by the height of 4.1, which gives you 49.2. You would then need to divide 49.2 by 2, which gives you 24.6. This is because the formula for the area of a triangle is the same as that of a square, however a triangle is half of a square with the same length and width. To work out the volume you would multiply the area of the triangle, which is 24.6 by the height of 9, which gives you 221.4[tex]m^{3}[/tex]
1) Multiply 12 by 4.1.
[tex]12*4.1=49.2[/tex]
2) Divide 49.2 by 2.
[tex]49.2/2=24.6[/tex]
3) Multiply 24.6 by 9.
[tex]24.6*9=221.4m^{3}[/tex]

Write the equation of the line that is parallel to the line and through the given point y=-2x+1 point (0,5)
Answer:
y = -2x+5
Step-by-step explanation:
y = -2x+1 is in the form y= mx+b where m is the slope and b is the y intercept
-2 is the slope
Parallel lines have the same slope so our new line will have the same slope
y = -2x+b
The point given is the y intercept (value when x is zero)
b = 5
y = -2x+5
Suri's age is 4 less than 3 times her cousin's age. Suri is 17 years old. Which method can be
used to find c her cousin's age?
Answer:
Add 4 to 17, then divide both sides by 3.
Step-by-step explanation:
Given that :
Suri's age is 4 less than 3 times her cousin's age
Suri is 17 years old
Let her cousin's age be c
Then ;
3c - 4 = 17
By adding 4 to 17; we have
3c = 17 + 4
3c = 21
Now, dividing both sides by 3 ; we have
3c/3 = 21/3
c = 7
The age of her cousin is 7 years
Answer:
Algebraic equation
Step-by-step explanation:
We would use an algebraic equation.
An algebraic equation is a mathematical statement in which two expressions are made equal to each other using the equal sign.
In this case the algebraic equation consists of constant, variables and algebraic operation.
One of the type of algebraic equation is a linear equation. The expression below relating suri's age with her cousin's is a linear equation.
We can derive equations from sentences that involves unknown values by representing them with variables such as x, y, etc.
Suri's age = 17years old
Let Suri's cousin's age = x
3 times her cousin's age = 3x
Suri's age = 4 less than 3 times her cousin's age = 3x-4
17 = 3x-4
3x = 17+4 = 21
x = 21/3
x = 7
Her cousins age = 3x = 3×7
Her cousins age = 21 years

Your answer would be the second option, (-4,5).
We can find this by substituting in each point into the equation y < |x - 3| and seeing if it is true.
For the first one you get 1 < |2 - 1|. |2 - 1| = |-1| = 1, and 1 cannot be less than itself, so this is false.
For the second one you get 5 < |-4 - 3|. |-4 - 3| = |-7| = 7, and 5 is indeed less than 7, so this is correct.
I hope this helps!

To find the probability of the next pizza not being a cheese pizza, we need to find how many pizzas in the sample weren't cheese by adding them up. This gives us:
14 + 23 + 14 = 51
The total number of pizzas made is 21 + 14 + 23 + 14 = 72.
Therefore the probability of not making a cheese pizza would be 51/72 = 0.708 = 0.71
