Sara is building a triangular pen for her pet rabbit. If two of the sides measure 8 feet and 15 feet, the length of the third side could be
1) 13 ft
2) 7 ft
3) 3 ft
4) 23 ft
Answer:
1) 13 ft
Step-by-step explanation:
1) 13+8=21 which is greater than 15. Would be a triangle.
2) 7+8=15 This would be a single line, not a triangle.
3) 3+8<15 This would be a single line, not a triangle.
2) 15+8=23 This would be a single line, not a triangle.

Answer:
B. 203.403
Step-by-step explanation:
2 times 100 = 200
3 times 1 = 3
4 times 1/10 = 0.4
3 times 1/1000 = 0.003
200 + 3 = 203
203 + 0.4 = 203.4
203.4 + 0.003 = 203.403

If the simple interest on 3,000$ for 3 years is 450$, then what is the interest rate?
Answer/Step-by-step explanation:
The interest rate is 15% for every 3 years. To find the interest rate subtract the money from the total. Then, divide the total from the difference. Now subtract the quotient from 100 and multiply it by 100 to fin the percentage.
3000 - 450 = 2550
2550 ÷ 3000 = 0.85
100 - 0.85 = 0.15
0.15 x 100 = 15%

Which of the following is the best approximation of the volume of the cylinder below?
Answer:
B
Step-by-step explanation:
[tex]v = \pi {r}^{2} h \\ = 8 \\ v = \pi {8}^{2} \times 3 = 3.14 \times 64 \times 3 = 602.88 = 602.9[/tex]
The volume of the cylinder is 2411.5 cm³ in the given figure. which is the correct answer would be an option (A).
What is the volume of a cylinder?The volume of a cylinder is equal to the product of the area of the circular base and the height of a cylinder.
V = πr²h
where 'r' is the radius of the base (circle) of the cylinder
'h' is the height of the cylinder
As per the given figure,
The radius of a cylinder is 16 cm and the height of the cylinder is 3 cm.
The volume of a cylinder = πr²h
The volume of a cylinder = π(16)² × 3
The volume of a cylinder = 3.14(256) × 3
The volume of a cylinder = 2411.5 cm³
Thus, the volume of the cylinder is 2411.5 cm³ in the given figure.

What is the equation of the line that passes through the point (6, 8) and has a slope 1/2
Answer:
y=1/2x+5
Step-by-step explanation:
Plug it into the formula for a point and a slope.
(y-(y(subscript 1)))=(m)(x-(x(subscript 1)))
Y-8=1/2(x-6)
Then multiply the 1/2 to the x and -6. After you do that, move everything so that it has y by itself on the left. Your ending should be y=1/2x+5.

You are planning the running shoe merchandise levels for your shoe store. Last year, your running shoe sales were down 10% from the previous season. The store had projected sales of 900 pairs of running shoes. Calculate the number of units the 10% sales decline represents.
Answer:
90
Step-by-step explanation: by taking 10% off of 900, you get 810; meaning 90 was subtracted
The number of units the 10% sales decline represents is 90
what is percentage?In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%"
Given here projected sales = 900 but the actual sales is 10% less than this amount , thus actual sales = 900 - 10% of 900
= 900 -( 10/100 )×900
= 900 - 90
= 810
Hence, the number of units the 10% sales decline represents is 900-810 =90

The measure of FG is
Answer:

Step-by-step explanation:
FG = EH ( being opposite sides of parallelogram)
3z + 8 = 5z - 14
5z - 3z = 8 + 14
2z = 22
z = 11
Now
FG = 3z + 8 = 3 *11 + 8 = 33 + 8 = 41

how to solve this one
Answer:
x= -7 and y=37
Step-by-step explanation:
substitute y=-26-9x in -2x-y=12
-2x-(-26-9x)=12
-2x+26+9x=12
-2x+9x=12-26
7x= -14
x= -14/2
x= -7
substitute x=-7 in y=26-9x
y= -26-9x
y= -26-9(-7)
y= -26+63
y=37
x= -7 and y=37

The solution to the quadratic equation is x = -6 ± 2√7
What is Quadratic Equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as A
Now , the value of A is
x² + 12x + 25 = 17
Subtracting 17 on both sides , we get
x² + 12x + 8 = 0
And , roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
On simplifying , we get
x = ( -12/2 ) ± √ ( 12 )² - 4 ( 1 ) ( 8 ) / 2
x = -6 ± √ ( 144 - 32 ) / 2
x = -6 ± √112/2
And , the value of x = -6 ± 2√28/2
x = -6 ± 2√7
Hence , the solutions are x = -6 + 2√7 and -6 - 2√7

the Peter age be 27
Step-by-step explanation:
Let assume peter be
And, then mary is 2p ÷ 3
So
The equation would be
2p ÷ 3 - 2 = 1 ÷ 2 (p + 5)
4p - 12 = 3p + 15
p = 27
So Peter age be 27
And, the mary age is
= 2 (27) ÷ 3
= 18
Hence, the Peter age be 27
