Answer:
10.35
Step-by-step explanation:
The given triangle is a right angled ∆ .The data given is ,
Base = x Hypontenuse = 23 Angle = 63° .We can use ratio of cosine here , as ,
=> cos∅ = b/h
=> cos 63° = x/23
=> 0.45 = x/23
=> x = 23 × 0.45
=> x = 10.35
Hence the value of x is 10.35Related Questions

If a histogram is right skewed, which will be greater the mean or the median? Type a single word answer in the space
provided, for example if the answer is mode, type mode.
Answers
Answer:
Mean is greater
Step-by-step explanation:
For a skewed distribution, then the tail is longer to one side from the center than to the other. In a right skewed distribution, the tail is longer to the right.
When a distribution is skewed, the mean will be closer to the tail Than the median. Therefore. For a right skewed histogram, the mean is closer to the tail of the histogram and hence closer to the right. Once this happens, values closer to the right of a distribution are higher (number line). Thus the mean will be greater than the median.

Complete the equation to show the relationship between the price and the weight w . P= _ w
Answers
Answer:
[tex]p = 0.3w[/tex]
Step-by-step explanation:
Given
[tex]w \to weight[/tex]
[tex]p \to price[/tex]
[tex](w,p) = (12,3.60)[/tex]
Required
The equation
First, we calculate the unit ratio (k)
This is calculated by dividing price by weight
[tex]k = p/w[/tex]
[tex]k = 3.60/12[/tex]
[tex]k = 0.3[/tex]
Recall that: [tex]k = p/w[/tex]
Make p the subject
[tex]p = kw[/tex]
Substitute [tex]k = 0.3[/tex]
[tex]p = 0.3w[/tex]

Andrew sold 60 baseball cards to a friend . This was 80% of Andrews total baseball card collection. How many total baseball cards where in Andrews collection ?
Answers
Answer:
75
Step-by-step explanation:
We know that 80% of Andrew's (former) baseball card collection is 60. Thus, We divide 60 by 80% (equal to 0.8) to obtain [tex]\frac{60}{0.8}=75[/tex].
Answer:
In total there were 75 cards in Andrews collection.
Step-by-step explanation:
We know that 60 is 80% of the total amount of cards Andrew has. Therefore, all we have to do to find the total number of baseball cards is to divide 60 by 80 to find 1% and then multiply the result by 100 to get 100% (the total amount of cards). And so we get...
60 / 80 x 100 = 60 / 0.8 = 75

Determine the perimeter of the shape below
Answers
Answer:
43.566 ft
Step-by-step explanation:
Straight sides: 2 long 1 short
2 x 10 + 8 = 28 ft
Curved side: Remember that the circumference of a circle is 2πr or πd.
Since this is a semicircle, divide the circumference you get by 2.
From the diagram: d = 8
total circumference = 8 x π = 8π
semicircle = 8π ÷ 2 = 4π ft
Total perimeter
= (28 + 4π) ft
= (28 + 12.566) ft (5sf)
= 43.566 ft (5sf)
The radius of the hemicircle is r = 8/2 cm = 4 cm.
So the perimeter of the hemicircle part is
[tex]\pi \times r \: = (22 \div 7) \times 4 = 12.57 \: cm[/tex]
The perimeter of the rectangular part = 10+10+8 = 28 cm.
So, the final answer is
[tex]28 \: cm + 12.57 \: cm = 40.57 \: cm[/tex]

Hi there!

I believe your answer is:
The square root of 5 ([tex]\sqrt{5}[/tex]) is irrational.
»»————- ★ ————-««
Here’s why:
A rational number is a number that can be rewritten as a fraction of two integers with a nonzero denominator. Rational numbers include integers, fractions, terminating decimal, or repeating decimals.A square root that is perfect would be rational. A non-perfect square root is irrational.⸻⸻⸻⸻
Since the square root of 5 is not a perfect square, it would be irrational.

Answers
Answer:
9^3 is Natural, Whole, Integer, and Rational
7/4 is Rational
√3 is Irrational
0 is Whole, Integer, and Rational
Thinking Process:
Alright, to start, with 9^3, it equal 729. This is a natural, whole, integer, and rational number. It is a natural number because it follows the counting (1, 2, 3...etc). Because of this, it is also part of all of the other rational categories as well.
With the next one, 7/4, this equals 1.75. It is not a natural, whole, or integer number because it is a decimal. However, it is rational, because it is still definite.
Next, with √3, this equals 1.73205.... It is irrational because it is not definite as it is a sequence of numbers that go on forever, being unpredictable in nature.
Last is 0, it is not a natural number because it does not follow the counting (1, 3, 3...etc). But it is whole because it follows the counting (0, 1, 2, 3...etc). This is along with it being an integer and rational because of this.
