Answer:
1) 10%
2) 50%
3)20%
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

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.
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

The sum of two consecutive integers is 53. What are the two integers?
Equation:
Integers:
Answer:
Equation: 2x+1 = 53 (x is 26)
Integers: 26, 27
Step-by-step explanation:
53 is the sum of 2 consecutive integers. That means one of the integers is one larger than the other. This means that twice one integer plus one equals 53, so the equation becomes x + (x + 1) = 53.
x + (x+1) = 53
Combine x and x to get 2x.
2x + 1 = 53
Subtract 1 from both sides to cancel the +1.
2x = 52
Divide both sides by 2 to undo the multiplication by 2.
x = 26
With this we know the first integer is 26. The second is one more than that, so that's 27. So the two integers here are 26 and 27.

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.

The area of a rectangle is 99yd^2, and the length of the rectangle is 7 wyd more than twice the width. Find the dimensions of the rectangle.
Law = 99 sq.
L = 2w + 7

Law = 99
(2w + 7)w = 99
2ww + 7w = 99
2ww + 7w - 99 = 0
