A tabletop in the shape of a trapezoid has an area of 5,350 square centimeters. Its longer base measures 135 centimeters, and the shorter base is 65 centimeters. What is the height?
Answer:
54 cm
Step-by-step explanation:
Using the formula for the area of a trapezoid (area is the sum of the two bases times the height and then halved):
A = 1/2 (h) (b1 + b2)
5350 = 1/2 (h) (135 + 65)
5350 = 1/2 (h) (200)
5350 = h (100)
5350/100 = h
h = 53.5
h ≈ 54 cm

A line passes through the point (-2, 2) and has a slope of – 6.
Write an equation in slope-intercept form for this line.
Answer:
y = -6x - 10
Step-by-step explanation:
(-2, 2), m = -6
Slope-intercept:
y - y1 = m(x - x1)
y - 2 = -6(x + 2)
y - 2 = -6x - 12
y = -6x - 10

What is the greatest common factor of 18, 24, and 40?
Answer:
The factors of 18 are: 1, 2, 3, 6, 9, 18
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40
Then the greatest common factor is 2.
The greatest common factor of 18 , 24 and 40 is HCF = 2
What is HCF and LCM?The Greatest Common Divisor GCF or the Highest Common Factor HCF is the highest number that divides exactly into two or more numbers. It is also expressed as GCF or HCF
Least Common Multiple (LCM) is a method to find the smallest common multiple between any two or more numbers. A common multiple is a number which is a multiple of two or more numbers
Product of HCF x LCM = product of two numbers
Given data ,
Let the HCF be represented as H
Let the first number be represented as p
Now , the value of p = 18
Let the second number be represented as q
Now , the value of q = 24
Let the third number be represented as r
Now , the value of r = 40
And , the factors of 18 = 1, 2, 3, 6, 9 and 18
The factors of 24 = 1, 2, 3, 4, 6, 8, 12 and 24
The factors of 40 = 1, 2, 4, 5, 8, 10, 20 and 40
So , the HCF of 18 , 24 and 40 is the number 2
Hence , the HCF is 2

john is a proud owner of a herd of cows 12 of them are brown and 32 are black what is the ratio of brown cows to the total number of cows?
Answer:
12:44, or if simplified 3:11
Step-by-step explanation:
In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8∶6, which is equivalent to the ratio 4∶3). Similarly, the ratio of lemons to oranges is 6∶8 (or 3∶4) and the ratio of oranges to the total amount of fruit is 8∶14 (or 4∶7).
Answer:
3 : 11
Step-by-step explanation:
Total number of cows = 32 + 12 = 44
Brown cows : Total
12 : 44 =
3 : 11

In the diagram below, XY is
tangent to OC at point P.
What is m
Answer:
90
Step-by-step explanation:
Tangents meet the end of a radius that is not at the center of a circle.
The tangent makes a 90 degrees angle with that end of the radius.
Answer:
m<CPX = 90°
Step-by-step explanation:
The line tangent to a circle states that when a line is a tangent to a circle, a radius that is drawn from the center to the circle to the point of tangency will be perpendicular to the tangent line
Apply this theorem to the given circle, one can state that (m<CPX= 90°) and (m<CPY = 90°), since (XY) is tangent to the circle will radius (CP).
Which number below is irrational?

Answer:
D. √ 52 = 2 * √ 13 irrational
Step-by-step explanation:
A. 3 √ 8 = 2 rational
B. 3√ 125 = 5 rational
C. √ 49 = 7 rational
D. √ 52 = 2 * √ 13 irrational
Answer:
The irrational number is [tex]\sqrt{52}[/tex].
Step-by-step explanation:
An irrational number is a non-terminating decimal number that does not follow any specific pattern (example: 0.333.... and 16.111... are all repeating with 3s and 1s, making them rational. While [tex]\sqrt{3}[/tex] or [tex]\sqrt{5}[/tex] are continuing decimals without a pattern, making them irrational). [tex]\sqrt[3]{8}[/tex], [tex]\sqrt[3]{125}[/tex], and [tex]\sqrt{49}[/tex] are all rational numbers, as they are equivalent to 2, 5, and 7 respectively. [tex]\sqrt{52}[/tex] can be written as [tex]\sqrt{4*13}[/tex] or [tex]2\sqrt{13}[/tex], since [tex]\sqrt{13}[/tex] is not a complete square root, which means that [tex]2\sqrt{13}[/tex] is an irrational number.

What is the length of the missing leg?
b =
kilometers
Answer:
28 km
Step-by-step explanation:
One leg = 35 km
Second leg = 21 km
We need to find the length of the missing leg. Using Pythagoras theorem, we can find it.
Hypotenuse² = base² + perpendicular²
[tex]x=\sqrt{35^{2}-21^{2}}\\\\x=28\ km[/tex]
So, the length of the missing leg is equal to 28 km.
