At a baseball game, 3 drinks and 4 hotdogs cost $15.00. At the same game, 3 drinks and 1 hotdog cost $10.50. Find the cost for a drink.
Answer:
$3
Step-by-step explanation:
Given data
Let the cost of drinks be x
and the cost of hotdogs be y
so
3x+4y=15-------1
also
3x+y= 10.5------2
solve 1 and 2
3x+4y=15
-3x+y= 10.5
3y= 4.5
divide both sides by 3
y= 4.5/3
y= $1.5
Put y= 1.5 in 1
3x+4(1.5)=15
3x+6= 15
3x=15-6
3x= 9
x= 9/3
x= $3
Hence the cost of a drink is $3

A small bottle contains 120 mL of juice. A large bottle contains 160 mL of juice. What is the ratio of the volume of juice in the small bottle to the volume of juice in the large bottle? A. 4 : 3 B. 3:5 C.3 : 4 D. 5:3
Answer:
3:4
Step-by-step explanation:
Given:
Small bottle volume = 120 mL
Big bottle volume = 160 mL
Find:
Ratio of small bottle to big bottles volume
Computation:
Ratio of small bottle to big bottles volume = 120 / 160
Ratio of small bottle to big bottles volume = 3/4
Ratio of small bottle to big bottles volume = 3:4

The measure of central angle RST is r radians.
What is the area of the shaded sector?
A. 41π units^2
B. 8π units^2
C. 16π units^2
D. 20π units^2
The area of the shaded sector of the circle is 16π units².
How to find the area of a circle?Suppose the circle has radius of 'r' units, then, its area is given as:
[tex]A = \pi \times r^2[/tex]
sq. units
Since radius of a circle is half of its diameter, so if diameter is of 'd' length, then r= d/2, thus, area can be rewritten as:
[tex]\pi \times (\dfrac{d}{2})^2[/tex]
sq. units
We are given that;
θ = r radians
r = 4 units
Now,
To convert radians to degrees, we use the formula:
Degrees = Radians × 180°/π
So,
θ = r × 180°/π
Substituting these values in the formula for area of a sector, we get:
Area of a sector = (r × 180°/π / 360°) × π(4)²
Simplifying, we get:
Area of a sector = r² units²
=16π units².
Therefore, by the area of a circle the answer will be 16π units².

If f(x) = - 3x3 -- x2 +8
what is f(-2)?
Answer:
f(-2) = 28
Step-by-step explanation:
Given that,
[tex]f(x) = - 3x^3 -x^2 +8[/tex]
We need to find the value of f(-2). Put x = -2 in the given function. SO,
[tex]f(-2) = - 3(-2)^3 -(-2)^2 +8\\\\=24-4+8\\\\=28[/tex]
So, the value of f(-2) is equal to 28.

Answer: It's either 278 or 178
Step-by-step explanation: I didn't know what equation the question wants you to use so for the first equation it showed I did (10^2+24+10+144) and got 278. For the second equation I did 24+10+144 and got 178. Considering it gave you ax+b as an area equation I just added them (same with the other equation). I don't know whether those are correct of not though.

Step-by-step explanation:
y = 3x + 10
Let x = 0 and evaluate the expression.
y = 3(0) + 10 = 0 + 10 = 10
Let x = 1 and evaluate the expression.
y = 3(1) + 10 = 3 + 10 = 13
Let x = 2 and evaluate the expression.
y = 3(2) + 10 = 6 + 10 = 16
Let x = 3 and evaluate the expression.
