Step-by-step explanation:
Surface area is the sum of the faces of all sides, so find the area of all sides and add
Answer:
40 mi²
Step-by-step explanation:
(see attached for reference)
the formula for surface area of a right rectangular prism
= 2(length x width) + 2(width x height) x 2(length x height)
in our case
length = 4 mi
width = 2 mi
height = 2 mi
substituting these values into the equation:
surface area
= 2(length x width) + 2(width x height) x 2(length x height)
=2(4)(2) + 2(2)(2) x 2(4)(2)
= 16 + 8 + 16
= 40 mi²
When an experiment result seems to only partly support a hypothesis, a researcher should consider which of the following?a. Accounting for the research biasesb. Exploring alternation explanationc. Formulating scientific lawd. Manipulating data
Answer:
b. Exploring alternation explanation
Step-by-step explanation:
Experiments are carried out in controlled conditions to confirm a known truth, examine the validity of a hypothesis, or evaluate the efficacy of something that has never been tried before.
SO, when an experiment result seems only partly to support a hypothesis, the best thing to do is to consider exploring alternative explanations through modification of the hypothesis.
A scientific should not be formulated because it is when we have a valid theory that we can formulate a scientific law.
Also, we cannot manipulate the experiment's data because it is not part of the code and conduct of carrying out research.
Charlie has—$19 in his bank account. This is $28 more then Steve’s bank account. How much money does Steve have in his bank account?
Answer:
may be incorrect but probably not -9
Step-by-step explanation:
19 - 28 = -9
2p - 6 = 8 + 5(p +9)
How do you solve it
Step-by-step explanation:
2p-6=8+5p+45
2p-6=53+5p
2p-5p=53+6
-3p=59
p=59/-3
p= -19.67

p = - 59/3
[tex]p=-19\frac{2}{3}[/tex]
Step-by-step explanation:2p - 6 = 8 + 5(p + 9)
2p - 6 = 8 + 5p + 45
- 6 - 8 - 45 = 5p - 2p
3p = - 59
p = - 59/3

In a recent year, 26.2% of all registered doctors were female. If there were 45,300 female registered doctors that year, what was the total number of registered doctors? Round your answer to the nearest whole number.
Answer:
798980 doctors
Step-by-step explanation:
In a recent year, 26.2% of all registered doctors were female. The total number of registered doctors is 172900.
What is the percentage?The percentage is a quantifiable way of comparing amounts with different totals. Because the percent is an equivalent fraction of the part with the whole, it is also a good way to get unknown amounts.
Percentages are basically fractions with a denominator of 100. We use the percent symbol (%) beside a number to indicate that it is a percentage. To calculate the percentage, divide the value by the total value and multiply the result by 100.
As given, 26.2% of all registered doctors are females.
Consider, the total number of registered doctors as x
26.2% of x are females
26.2% of x is 45,300
26.2 / 100 × x = 45,300
x = 45,300 × 100 / 26.2
x = 172900.76
Therefore, the total number of registered doctors is 172900.

Answer:
The slope of the line is -2.5.
Step-by-step explanation:
The formula to compute the slope of a straight line is:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
The graph shows the gift card balance after buying 2 and 5 cups of medium coffee.
The two points provided are:
A = (1, 17.50)
B = (5, 7.50)
Compute the slope of the line as follows:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]=\frac{7.50-17.50}{5-1}\\\\=\frac{-10}{4}\\\\=-2.5[/tex]
Thus, the slope of the line is -2.5.

A cone is cut out of the center of a pyramid with a rectangular base. The rectangular base has side lengths of 15 and 10 units. The cone has a diameter of 9 and a height of 12. The pyramid and cone have the same height. What is the volume of the shaded portion of the composite figure? Express your answer in terms of π. 519π units3 681π units3 (600π – 81) units3 (600 – 81π) units3
Answer:
Volume of shaded portion = (600 - 36π) units³
Step-by-step explanation:
Volume of the shaded portion = Volume of pyramid - Volume of cone
Volume of pyramid = ⅓*l*w*h
Where,
l = length of base of pyramid = 15 units
w = width of base of pyramid = 10 units
h = height of pyramid = 12 units
Plug in the values to find the volume of the pyramid
Volume of pyramid = ⅓*15*10*12 = 5*10*12 = 600 units³
Volume of Cone = ⅓πr²h,
Where,
r = radius = ½ of diameter = ½ of 9 = 3 units
h = height = 12 units
Volume of Cone = ⅓*π*3²*12 = ⅓*π*9*12
= π*3*12 = 36π units³
Volume of shaded portion = (600 - 36π) units³
Answer:

Step-by-step explanation:
The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times the measure of the first angle. The third angle is 26 more than the second. Let x, y, and z represent the measures of the first, second, and third angles, respectively. Find the measures of the three angles.
Answer:
(x, y, z) = (30°, 62°, 88°)
Step-by-step explanation:
The given relations are ...
x + y + z = 180 . . . . sum of angle measures is 180°
y + z = 5x . . . . . . . . sum of 2nd and 3rd is 5 times the first
z = y + 26 . . . . . . . . third is 26 more than second
__
We can use the third equation to substitute into the second equation.
y + (y +26) = 5x
2y +26 = 5x
We can multiply the first equation by 5, then substitute for 5y and for z.
5x +5y +5z = 5(180)
(2y +26) +5y +5(y +26) = 900
12y + 156 = 900 . . . simplify
y +13 = 75 . . . . . . . . divide by 12
y = 62
z = y + 26 = 62 +26 = 88
y+z = 5x = 62 +88 = 150
x = 150/5 = 30
The angle measures are (x, y, z) = (30°, 62°, 88°).
Answer:
x=30 y=62 z=88
Step-by-step explanation:
The solution is therefore (30,62,88).
if one card is picked at random from a deck of 52 cards which contains an equal amount of hearts, diamonds, clubs, and spades, the probability that it is a club is
Answer:
25%.
Step-by-step explanation:
Since there are 52 cards, and 4 suits, you must find the number of cards for each suit. Begin by dividing 52 by 4.
52 / 4 = 13.
Now, we must check how many times 13 goes into 52. It goes in 4 times (4 x 13 = 52).
Because it is exactly 52, not over, we can find the percent by dividing 100 by the number of times 13 went into 52!
Since it went in 4 times, we will get the answer with this final equation:
100 / 4 = 25.
Therefore, the answer is 25%!

[tex]\frac{z}{sinL}[/tex] = [tex]\frac{y}{sinH}[/tex] → (b)

[tex]\frac{sinL}{z}[/tex] = [tex]\frac{sinH}{y}[/tex] → (a)
Thus the law of Sines can be expressed as either (a) or (b)

The distance from Gillette, New Jersey, to Irvington, New Jersey, is 1 mile more than four times the distance from Irvington to Newark. If the total distance from Gillette to Newark is 2 miles less than six times the distance from Irvington to Newark, what is the distance from Irvington to Newark if all three cities are in a straight line?
Answer:
distance from Irvington to Newark
.= 3 Miles
Step-by-step explanation:
distance from Irvington to Newark.= X
distance from Gillette, New Jersey, to Irvington, New Jersey,= y
Y= 1+4x
total distance from Gillette to Newark
= z
Z= 6x-2
But total distance = x+y
Total distance= x+1+4x
Total distance= 1+5x
1 +5x= 6x-2
1+2= 6x-5x
3= x
distance from Irvington to Newark.= X
distance from Irvington to Newark
.= 3 Miles
distance from Gillette, New Jersey, to Irvington, New Jersey,= 1+4x
distance from Gillette, New Jersey, to Irvington, New Jersey,= 1+4(3)
distance from Gillette, New Jersey, to Irvington, New Jersey,= 1+12
distance from Gillette, New Jersey, to Irvington, New Jersey,= 13 miles
Total distance= 1+5x
Total distance= 1+5(3)
Total distance= 16 miles
