A holiday tree is 4 feet 8 inches tall. There are 2.54 centimeters in one inch. What is the tree’s height in centimeters?
Answer:
The tree's height is 142.24 cm.
Step-by-step explanation:
There are 12 inches in a foot. This means that 4 feet equal 4 * 12 = 48 inches. Since there are 8 more inches, you add 8 to 48. The sum is 56. There are 56 inches in 4 feet and 8 inches.
Now, to convert:
56 * 2.54 = 142.24 (inches to centimeters)
The tree's height is 142.24 cm.

The time T, necessary to make an enlargement of a photo negative,
varies directly to the area, A, of the enlargement. If 36 seconds are
required to make a 2-by-3 enlargement, find the time required for a
5-by-11 enlargement.
Answer:
330 seconds (5 minutes, 30 seconds)
Step-by-step explanation:
You want the time required for a 5×11 enlargement when a 2×3 enlargement takes 36 seconds, and time is proportional to area.
AreaThe area of a rectangle is the product of length and width.
area of smaller enlargement: 2×3 = 6
area of larger enlargement: 5×11 = 55
TimeThe time is proportional to the area, so when the area increases by a factor of 55/6, so does the time:
(36 seconds) × (55/6) = 330 seconds
The time required for a 5×11 enlargement is 330 seconds.

According to Investment Digest ("Diversification and the Risk/Reward Relationship", Winter 1994, 1-3), the mean of the annual return for common stocks from 1926 to 1992 was 16.5%, and the standard deviation of the annual return was 19%.
What is the probability that the stock returns are less than 18.5%
The probability that perhaps the stock returns will be less than 18.5% is 0.542.
The normal distribution is:In most cases where the possible study population is large, a normal distribution is chosen. Apart from its easier application than that of other distribution methods, this is the primary reason for its efficiency.
According to the given information:Let X be the annual return on common stocks throughout 1926 to 1992.
The average of X is 16.5%.
X has a standard deviation of 19%.
Assume X is regularly distributed.
X∼N(μ,σ)
∼N(16.5,19)
The likelihood that stock returns seem to be less than 18.5% is calculated using the Z-table, as shown below.
P(X < 18.5) = [tex]P\left(\frac{X-\mu}{\sigma} < \frac{18.5-16.5}{19}\right)[/tex]
= P(Z < 0.1053)
= 0.542
The probability that perhaps the stock returns will be less than 18.5% is 0.542.

David Egil and frances share money in the ratio 2:7:9 Egil gets £85 more than David work out how much they each get ?
Answer:
David gets £34, Egil gets £119 and Frances gets £153.
Step-by-step explanation:
Let the amount of money David gets be 2x, Egil be 7x and Frances be 9x.
7x = 2x + 85
7x - 2x = 85
5x = 85
x = 85 ÷ 5
x = 17
David (2x) = 2 × £17
= £34
Egil (7x) = 7 × £17
= £119
Frances (9x) = 9 × £17
= £153

In a different tug of war, one team pulls with a force of 50 newtons at an angle of 30 degrees from the positive x-axis, and a second team pulls with a force of 25 newtons at an angle of 250 degrees. Use a scale drawing to determine the total force and angle applied to the central ring. How did they get the following answer?34.8 N at 2.5 degrees from the positive x-axis
Answer:
34.8 N at 2.5 degrees from the positive x-axis
Step-by-step explanation:
From the given information:
The force F makes an angle A with the positive x axis can be expressed in terms horizontal and vertical components.
[tex]F_x = F cos A\\\\ F_y = Fsin A[/tex]
Given that
[tex]F_1 = 50 \ N[/tex]
[tex]\theta_1 = 30 ^0 \ \ \ (x-axis)[/tex]
[tex]F_{1x} = F_1 \times Cos A_1[/tex]
= 50 × cos 30
= 43.3 N
[tex]F_{1y} = F_1 \times Sin \ A_1[/tex]
= 50 × sin 30
= 25 N
Similarly;
[tex]F_2 = 25 \ N[/tex]
[tex]\theta_2 = 250 ^0 \ \ \ ( x-axis)[/tex]
[tex]F_{2x} = F_2 \times cos \ A_2[/tex]
= 25 × cos 250
= - 8.55 N
[tex]F_{2y} = F_2 \times A_2[/tex]
= 25 × sin 250
= -23.5 N
The total net force;
[tex]F_{net} = F_{(net)}_x + F_{(net)}_y[/tex]
[tex]F_{net} = (F_{1x} + F_{2x} ) i + (F_{1y} + F_{2y} )j[/tex]
[tex]F_{net} = (43.3 - 8.55) i + (25-23.5 ) j[/tex]
[tex]F_{net} =34.75 i + 1.5 j[/tex]
[tex]|F_{net} | = \sqrt{F_{net}_x^2 + F_{net}_y^2}[/tex]
[tex]|F_{net} | = \sqrt{34.75^2 + 1.5^2}[/tex]
[tex]|F_{net} | = 34.8 \ N[/tex]
Finally, the direction of the angle for the net force is:
[tex]tan \theta = \dfrac{F_{net_y}}{F_{net_x}}[/tex]
[tex]\theta = tan^{-1} \Big (\dfrac{F_{net_y}}{F_{net_x}} \Big)[/tex]
[tex]\theta = tan^{-1} \Big (\dfrac{1.5}{34.75}} \Big)[/tex]
[tex]\theta = tan^{-1}( 0.043165)[/tex]
[tex]\theta \simeq 2.5^0\ with \ positive \ x-axis[/tex]
Find the equation for the line of best fit using the two points that are close to the line of best fit (2,70) and (4.5, 90)
Given:
Two points that are close to the line of best fit are (2,70) and (4.5, 90).
To find:
Th equation of best fit line using the given two points.
Solution:
We know that, if a line passes through the two points, then the equation of line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
Two points (2,70) and (4.5, 90) are close to the best fit line.
Consider the two points (2,70) and (4.5, 90). So, the equation of line is
[tex]y-70=\dfrac{90-70}{4.5-2}(x-2)[/tex]
[tex]y-70=\dfrac{20}{2.5}(x-2)[/tex]
[tex]y-70=8(x-2)[/tex]
[tex]y-70=8x-16[/tex]
Adding 70 on both sides, we get
[tex]y=8x-16+70[/tex]
[tex]y=8x+54[/tex]
Therefore, the equation of best fit line is [tex]y=8x+54[/tex].

VERY URGENT !Gloria texts 18 words in the same
amount of time it takes Erica to text
25. Assuming the relationship is
proportional, if Erica texted 500 words,
how many did Gloria text?
Answer:
Gloria would text 360 words if Erica texted 500 words.
Step-by-step explanation:
Let 'y' be the number of words Gloria texts
Let 'x' be the number of words Erica texts
Given that the relationship is proportional
y ∝ x
y = kx
where 'k' is called the constant of proportionality
Given
y = 18x = 25substituting the values to determine the constant of proportionality 'k'
k = y / x
= 18 / 25
Thus, the constant of proportionality = k = 18/25
When Erica texted 500 words, we need to determine the number of words Gloria will text.
so
k = 500
y = ?
k = y / x
y = kx
= 18 / 25 × 500
= 360 words
Thus, Gloria would text 360 words if Erica texted 500 words.
Find the sale price of the item. Round to two decimal places if necessary.
Original price: $84.00
Markdown: 32%
The sale price is
Answer:
[tex]Sales\ Price = \$57.12[/tex]
Step-by-step explanation:
Given
[tex]Price = \$84.00[/tex]
[tex]Markdown = 32\%[/tex]
Required
Determine the sales price
First, we calculate the markdown price.
This is calculated by multiplying the original price the markdown percentage
[tex]Markdown\ Price = \$84.00 * 32\%[/tex]
Convert % to decimal
[tex]Markdown\ Price = \$84.00 * 0.32[/tex]
[tex]Markdown Price = \$26.88[/tex]
The sales price is then calculated as:
[tex]Sales\ Price = \$84.00 - \$26.88[/tex]
[tex]Sales\ Price = \$57.12[/tex]
Hence, the sales price after markdown is $57.12

two integers, a and b, have different signs. the absolute value of inter a is divisible by the absolute value of integer b. Find two integers that fit this description. Then decide if the product of the integers is greater than or less than the quotient of the integers.
Two numbers that meet the condition are a = -10 and b = 2, and the quotient between these is larger than the product.
How to find two integers that fit the description?
We have two numbers a and b with different sign.
Let's say that a is negative and b positive.
We know that the absolute value of a is divisible by the absolute value of b.
|a|/|b|
Then we have that |a| ≥ |b|
An example of two numbers that meet these conditions are:
a = -10
b = 2
Where:
|-10|/|2| = 10/2 = 5
Now, the product between the integers will give a large negative number, in this case:
-10*2 = 20
and the quotient will give a smaller, in absolute value, negative number:
-10/2 = -5
Then we can see that the quotient is larger (as both are negative numbers, and the quotient is closer to zero).
