A barbeque restaurant serves four meats: brisket, chicken, ribs, and turkey. How many two-meat combos can be served for the luncheon plate? [?] meat combos
Answer:
6 ways
Step-by-step explanation:
Given that:
Number of options, n = 4
Combo, r = 2
Using Combination :
nCr = n! ÷ (n-r)! r!
4C2 = 4! ÷ (4-2)!2!
4C2 = 4! ÷ 2!2!
4C2 = (4 * 3) / (2 * 1)
4C2 = 12 / 2
4C2 = 6

Find the equation of the linear function represented by the table below in slope-
intercept form.
Answer:
y = -2x-5
Step-by-step explanation:
So to calculate the slope the equation is y1-y2/x1-x2. We substitute in two points, let's use (-3,1) as x1 and y1, and (1,-7) as x2 and y2. Put those points in the equation and you get -7-1/1-(-3), which is -2. Now you have y=-2x+b
To get b plug in a pair of points to the equations, say (1,-7). -7=-2(1)+b, solve that and you get b=-5.
So y=-2x-5.
Ronnie bought 6 ice cream cones for himself and his friends. Seventeen cents tax was added to the price of each cone. The total cost was $14.58.
Answer:
Step-by-step explanation:
Since the tax is 17¢, then you have to subtract that from 14.58
14.58-.17=14.41
14.41/6
$2.40
Eric dropped a ball from a three story building that was 30 feet tall. After the ball landed it bounced 85% the height of the previous height. Write the explicit form to represent the height of the ball after each bounce.
Answer:
[tex]y= 30-0.85x[/tex]
Step-by-step explanation:
Given data
Height of building= 30ft
We are told that after the ball landed it bounced 85% the height
let the new height be y
So the expression for the new height for x number of bounces is
[tex]y= 30-0.85x[/tex]

The ratio of boys to students is 3 to 7. If there are 20 girls in the school, then how many boys are in the school?
Answer:
No. of boys = 15
Step-by-step explanation:
Given that,
The ratio of boys to student is 3:7.
Number of girls in the school = 20
We need to find the number of boys in the school.
Let there are 3x boys and 7x number of students.
No. of girls = Total students - no. of boys
= 7x-3x
= 4x
ATQ,
4x = 20
x = 5
No. of boys = 3x
= 3(5)
= 15
Hence, there are 15 boys in the school.

Complete question :
A cooler contains 4 L of water. The cooler has marks on it at every 0.2 L. Water bottles are filled with water from the cooler, and each bottle holds approximately 4/9L. After 4 water bottles are filled, between which two marks is the water level in the cooler? Show your work.
Answer:
2.2 - 2.4 Litre
Step-by-step explanation:
Capacity of cooler = 4L
Marking on cooler = every 0.2L
Capacity of bottle = 4/9 L
Number of bottles filled = 4
Total volume filled = (4/9) * 4 = 16/9 L = 1.78L
Volume of water left in tank :
(4 - 1.78)Litre
= 2.22 litres
Since, the tank is marked at 0.2 L interval ; the water level will be between 2.20 to 2.40 litres

A 60-kg robot walks at 1 m/s. What is the robot's kinetic energy?
Answer:
[tex]\boxed {\boxed {\sf 30 \ Joules}}[/tex]
Step-by-step explanation:
Kinetic energy can be found using the following formula:
[tex]KE=\frac{1}{2}mv^2[/tex]
Where m is the mass and v is the velocity.
The robot has a mass of 60 kilograms and a velocity of 1 meter per second.
[tex]m= 60 \ kg \\v= 1 \ m/s[/tex]
Substitute the values into the formula.
[tex]KE=\frac{1}{2} (60 \ kg) (1 \ m/s)^2[/tex]
Solve the exponent first.
(1 m/s)²= 1 m/s * 1 m/s = 1 m²/s²[tex]KE= \frac{1}{2} ( 60 \ kg )(1 m^2/s^2)[/tex]
Multiply the numbers in parentheses.
[tex]KE=\frac{1}{2} ( 60 \ kg*m^2/s^2)[/tex]
Multiply by 1/2 or divide by 2.
[tex]KE= 30 \ kg*m^2/s^2[/tex]
1 kg*m²/s² is equal to 1 J Our answer: 30 kg*m²/s² is equal to 30 Joules[tex]KE= 30 \ J[/tex]
The robot's kinetic energy is 30 Joules

4)70%
5)75%
6)40%
7)56.25%
8)83.33%
10)35%
Step-by-step explanation:
1) write it as a fraction 1/10 = 0.10 multiply by 100 to remove the decimal point you are left with 10 so the answer is 10%
2) write as a fraction 10/20. Simplify 10 divided by 10 =1
20 divided by 10 =2
Write as a fraction 1/2 = 0.50 multiply by 100 to remove decimal point to get 50. So the answer is 50%
Triangle ABC is a sketch of a triangular flower bed that has an area of 65.1 square feet. Triangle A B C is shown. The length of A B is 13 feet, the length of B C is 10 ft, and the length of A C is b. Angle B C A is 50 degrees. Trigonometric area formula: Area = One-half a b sine (C) To the nearest foot, what amount of fencing is needed to surround the perimeter of the flower bed? 17 feet 33 feet 40 feet 50 feet
Answer:
40 feet
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as isosceles triangle, equilateral triangle, scalene triangle, right angled triangle.
The area of triangle ABC is given as:
Area = (1/2) * AC * BC * sin(C)
But C = 50°, Area = 65.1 ft², BC = 10 ft, AC = b, AB = 13 feet.
Substituting gives:
65.1 = (1/2) * b * 10 * sin(50)
3.83b = 65.1
b = 17 ft
Perimeter of ΔABC = AB + AC + BC = 17 + 13 + 10
Perimeter of ΔABC = 40 feet
Answer:
40 feet
