A right triangle has an area of 98 square inches. If the triangle is not an Isosceles triangle, what are the all possible lengths of the legs?
Answer:
The possible length of the triangle =
1) (1inches, 196inches)
2) (2incheq, 98inches)
3) (4inches , 49 inches)
4) (7 inches , 28 inches)
Step-by-step explanation:
We are told the above Triangle is not an Isosceles Triangle
Hence, we assume it is a right angle triangle
The area of a triangle is = 1/2 × Base × Height
= let us represent Base and Height = x
Hence:
1/2 × x × x = 98
x² /2 = 98
Cross Multiply
x² = 98 × 2
x² = 196
Step 2
We find the factors of 196
1× 196 = 196 (1, 196)
2 × 98 = 196 (2, 98)
4 ×49 = 196 (4, 49)
7 × 28 = 196 (7, 28)
Therefore, all the possible length of the triangle =
1) (1inches, 196inches)
2) (2incheq, 98inches)
3) (4inches , 49 inches)
4) (7 inches , 28 inches)

if the 55 employees who work overtime make up approximately 42% of all employees at the company, how many employees are there in total
Answer:
Approximately = 131 employees in total
Step-by-step explanation:
if the 55 employees who work overtime make up approximately 42% of all employees at the company, how many employees are there in total?
Let us represent total number of employees = x
Hence,
42% of x = 55 employees
42/100 × x = 55
42x/100 = 55
Cross Multiply
42x = 100 × 54
x = 100 × 55/42
x = 130.95238095 employees
Therefore, there is approximately a total 131 employees

the sum of two numbers is 30 the difference between three times the first number and twice the second is 60
Answer
Let the first no. be 2x
second no. =x
third no. =2x/3
A/Q
2x+x+2x/3=132
11x/3=132
x=36.
Hence the second no. is 36
let the first number be x
then second number=30-x
3x-2(30-x)=60
3x-60+2x=60
x=60+60
x=120

Answer:
6 and 12
Explanation:
(b.) is under set A but not set B, meaning that all the elements there are multiples of 3 that are not odd numbers.
all the multiples of 3 that are less than 16: 3 6 9 12 15
all the multiples of 3 that are even numbers: 6 12
thus, the elements that go in (b.) are 6 and 12.

6 cm 4 cm 10 cm What is the surface area of the figure?
Answer:
248 cm^2
Step-by-step explanation:
in order to get the figures surface area you only need to find the area of all 6 sides
in this case the two ends are 4 by 6
the front and back are 10 by 6
and the top and bottom are 10 by 4
this would mean that we need to multiply
(4*6)*2
(10*6)*2
(10*4)*2
which would look like
(4*6)*2= (24)*2= 48
(10*6)*2= (60)*2=120
(10*4)*2= (40)*2=80
and finally the sum of the equations is the surface area of the figure
48+120+80=248
Carlos is extending hood backyard patio. Currently, the area of the patio is n2+16n+64. West are the new length and width of the patio, feet, if Carlos extends the length by 2 feet and the width by 2 feet
Answer:
Width = 8 feet
Length = 8 feet
Step-by-step explanation:
Carlos is extending hood backyard patio. Currently, the area of the patio is n²-16n+64.
Step
We find the Length and Width
This is done by factorising the area
Area = n² - 16n + 64 = 0
n² - 8n - 8n + 64 = 0
(n² - 8n) - (8n +64) = 0
n(n - 8) -8(n - 8) = 0
(n - 8) (n - 8) = 0
n - 8 = 0
n = 8
The length and width = 8 feet
Step 2
New length and width by extension is calculated as:
Width = 8 feet + 2 feet = 10 feet
Length = 8 feet + 2 feet = 10 feet
A six sided die is rolled and a spinner with 5 equal spaces labeled A-E is spun. Find the P(rolling
a 1 and spinning A). Answer as simplified fraction.
Answer:
1 / 30
Step-by-step explanation:
For a six - sided die :
Sample space = (1, 2, 3, 4, 5, 6)
P(rolling a 1) = required outcome / sample space = 1/6
Sample space for spinner = (A, B, C, D, E)
P(spinning A ) = required outcome / sample space = 1/5
P(spinning A) = 1 / 5
P(rolling a 1 and spinning A) = P(rolling a 1) * P(spinning A) = 1/6 * 1/5 = 1 / 30
(1)/(4p)(x-h)^(2)+k=0 Multiply the equation by 4p. Explain how different values of k affect the number of zeros of the polynomial. Consider k > 0, k = 0, and k < 0. Assume p > 0.
Answer:
Step-by-step explanation:
Assume that and multiply the equation by 4p. Then you obtain the equation (x-h)^2+4pk=0.
1) If k>0, then 4pk>0 and the equation does not have real solutions and there is no zero.
2) If k=0, then 4pk=0 and . There is one solution x=h and there is one zero.
2) If k<0, then 4pk<0 and the equation has two different solutions and there are two zeros.
Answer:
Given equation:
[tex]\frac{1}{4p} (x - h)^2 + k = 0[/tex]Multiply this by 4p to get:
(x - h)² + 4pk = 0Rewrite this as:
(x - h)² = 4pk1) If p > 0 and k < 0
(x - h)² < 0, then no real solutions as left side is always positive2) If p > 0 and k = 0
(x - h)² = 0, then x = h, one solution = 1 zero3) If p > 0 and k > 0
(x - h)² > 0, then there 2 real solutions = 2 zeros:x = h ± 2[tex]\sqrt{pk}[/tex]Please I need help now! This is due today! Look at the pic below.

please help need answer
Answer:
$3
Step-by-step explanation:
3 dollars because
1 pound = 16 ounces
and 1 pound costs 1.5 dollars
if there are 32 ounces of broccoli, you divide the number of ounces by 16 and multiply that by 1.5
32/16 = 2 x 1.5 = 3
Answer:
$3.00
Step-by-step explanation:
Since 1 pound = 16 ounces and there are 32 ounces, by dividing 32/16 will equal to 2 pounds, hence $1.50 x 2 =$ 3.00

Mark's scores on his first nine assignments were: 10, 10, 9, 9, 10, 8, 9, 10, and 8.
a. What are the median and range of his scores?
b. What is his mean (average) score so far?
c. Mark did not do the tenth assignment, so he got a zero on it. Zero is an outlier for these assignments. What is his new mean?
If you help me with my last question I will help you with this one
Answer:
Median= 9
Range= 2
Mean= 9.2
Mean after zero= 8.3
Step-by-step explanation:
8, 8, 9, 9, 9, 10, 10, 10, 10
Median= order from least to greatest then eliminate from left to right until you get to the middle
Range= Subtract biggest # minus smallest #
Mean= add up all the numbers then divide by 9
Mean after zero= add 0 with other numbers then divide by 10

Answer:
98
Step-by-step explanation:
I do not understand this at all!
Answer:
∠1 = 51° ∠2 = 39°
Step-by-step explanation:
ok since the picture is a right angle put it equal to 90
like this:
3x + x + 22 =90
4x + 22 = 90
4x = 68
x = 17
now we plug it in:
3(17)= 51°
(17) + 22 = 39°
*a straight line is equal to 180, a right angle is 90
does that make sense?

Write an expression that is equivalent to: -1/2(10 + 1/4)
Answer:
Step-by-step explanation:
-1/2(10 + 1/4)
10+1/4 = 41/4
Since the denominator is 4, you multiply 10 by 4 to make it equivalent since 10 is a whole number and 1/4 is a fraction
-1/2(10.25)= -41/8 or 5.125
