Answer:
25.5
Step-by-step explanation:
Using SOH CAH TOA, you can see that x is the hypotenuse, and 24 is adjacent to the angle 20, so you will need to use CAH.
CAH is cos=adjacent/hypotenuse. Substituting our values in means cos(20) will be equal to 24/x. By cross multiplying, you receive cos(20) x =24. To find x, divide 24 by cos(20) to get 25.5 to the nearest tenth.

Step-by-step explanation:
2 cm represents 100 miles, then 1 cm represents 50 miles and .5 cm represents 25 miles.
Town A = 175 miles from town B.
Town C = 100 miles from town B.
SO, Town A is 175 miles + 100 miles = 275 miles from town C.

The number of newly reported crime cases in a county in New York State is shown in the accompanying table, where x represents the number of years since 2008, and y represents number of new cases. Write the linear regression equation that represents this set of data, rounding all coefficients to the nearest hundredth. Using this equation, find the projected number of new cases for 2016, rounded to the nearest whole number.
Answer:
Step-by-step explanation:
If you don't know how to use your calculator to find a regression equation, that is much too much to try and teach you in a forum such as this (it takes all hour to teach Algebra 2 students during the school year and they are sitting in class watching a demonstration!). I entered the data in my calculator and got the equation to be
y = 18.9x + 850 with a correlation coefficient of only .8 so this is not a very good model for this data anyway. However, we will proceed with the question as it asks. Year 0 is 2008, so the year in question, 2016, is year 8. We fill in the model with 8 for x and solve for y, the cases in NY of crime in that year:
y = 18.9(8) + 850 and
y = 151.2 + 850 so
y = 1001 cases of crime

Robbert wants to put lights around the edge of his yard.The yard if 40 feet long and 23 feet wide.How many yards of light does he need
Answer:
102.222 square yards of light.
Step-by-step explanation:
From the above question, the yard had the dimensions 40 feet long and 23 feet wide.
Hence, the yard is rectangular in shape.
We have to find the area of the yard.
The formula is given as:
Area = Length × Width
= 40 feet × 23 feet
= 920 square feet
Converting to yards
1 square foot = 0.111 square yard
920 square feet = x
Cross Multiply
x = 920 × 0.111 square yard
x = 102.222 square yards.
Therefore, Robbert would need 102.222 square yards of light.
Help plz math question. EXPLAIN HOW YOU GOT THE ANSWER. 30 PTS btw thx if u help
Answer:
256
Step-by-step explanation:
4^4^4 = 4^(4^4) = 4^256
so written in base 4, there will be 256 zeroes after a 1.
This translates to approximately 154 digits in decimal.
Just like 2^2^2 = 2^4
there will be four zeroes after a 1.
2^2^2=2^(2^2) = 2^4 = 16 = 10000 (16 in base 2).

Five children have heights of 138cm, 135cm, 140cm, 139cm, and 141cm.
What is the range of their heights?
Answer:
6 cm
Step-by-step explanation:
To find the range take the largest number and subtract the smallest number
The largest number is 141 and the smallest number is 135
141 - 135 = 6 cm

On Sunday, the wind chill temperature reached −36 °F. On Monday, the wind chill temperature only reached 1 4 of Sunday's wind chill temperature. What was the lowest wind chill temperature on Monday? A −144 °F B −36 1 4 °F C −9 °F D −40 °F
Answer:
(A) -9 °F
Step-by-step explanation:
On Sunday, the wind chill temperature reached - 36 °F. On Monday, the wind chill
temperature only reached¼ of Sunday's wind chill temperature. What was the
lowest wind chill temperature on Monday? (A) -9 °F (B) -36¼°F (C) -40 °F (D) -144 °F
Sunday temperature = - 36 °F
Monday temperature = ¼ of Sunday's wind chill temperature
Monday = 1/4 of - 36 °F
= 1/4 * -36 °F
= (1 * -36)/4 °F
= -36/4 °F
= -9 °F
Monday temperature = -9 °F
The correct answer is (A) -9 °F

The height in meters of a projectile involves the object's initial height,
upward velocity, and acceleration because of gravity. If the equation
y =- 9.8t + 109.7t + 7.4 models the number of meters, y, a toy rocket
is above the ground t seconds after being launched, what does the 7.4
represent?
Answer: Initial height before launch
Step-by-step explanation:
Given
The equation [tex]y=-9.8t+109.7t+7.4[/tex] the height of toy rocket after t sec
when the rocket is launched, time is [tex]t=0[/tex]
Substituting 0 for [tex]t[/tex] in the equation
[tex]\Rightarrow y(0)=-9.8(0)+109.7(0)+7.4\\\Rightarrow y(0)=7.4[/tex]
Here, [tex]7.4[/tex] represents that rocket is already at a height of [tex]7.4[/tex] m before the launch.
At Anthony's school, 260 of the 500 students are girls. At Theresa's school, 360 of the 600 students are girls. Whose school has the greater percent of girls.
Answer:
Theresa school has greater % of girls
Step-by-step explanation:
Given
Number of girl in the Anthony school = 260
Total student in Anthony school = 500
% of girl in the Anthony school = 260/500 * 100 = 52 %
Number of girl in the Theresa school = 360
Total student in Theresa school = 600
% of girl in the Theresa school = 360/600 * 100 = 60%
Theresa school has greater % of girls
Find the theoretical probability that the spinner below lands on the letter B. Write your answer as a fraction in simplest form. Use "/" for fractions with no s
Answer:
The theoretical probability that the spinner below lands on the letter B is 1/2
Step-by-step explanation:
Given
[tex]S =\{A,B,B,B,C,C\}[/tex]
[tex]n(S) = 6[/tex]
See attachment for spinner
Required
P(B)
From the attached spinner, we have:
[tex]n(B) = 3[/tex] --- occurrence of B
So:
[tex]P(B) = \frac{n(B)}{n(S)}[/tex]
[tex]P(B) = \frac{3}{6}[/tex]
[tex]P(B) = 1/2[/tex]

A sphere used in a contest has a
diameter of 9 feet. What is the
volume of the sphere?
Answer:
382 ft³ (3 s.f.)
Step-by-step explanation:
[tex]\boxed{volume \: of \: sphere = \frac{4}{ 3}\pi {r}^{3} }[/tex]
Radius= diameter ÷2
Rdaius of sphere
= 9 ÷2
= 4.5 ft
Volume of sphere
[tex] = \frac{4}{3} (\pi)(4.5)^{3} [/tex]
= 382 ft³ (3 s.f.)
20+(5 + 7) = x - 14 I need help take your time
Answer: x = 46
Step-by-step explanation: 20 + (5 + 7) = x - 14, 20 + (12) = x - 14
Answer:
[tex]x=46[/tex]
Step-by-step explanation:
[tex]20 + (5+7)=x-14[/tex]
[tex]20+12=x-14[/tex]
[tex]32=x-14[/tex]
Take [tex]x-14[/tex] on the other side of the 'equal to' sign and 32 on the other side so that the variable remains on the right side
[tex]x-14=32\\[/tex]
[tex]x=32+14[/tex]

A rectangular block of wood measures 5 inches wide. Over time, the width of the block of wood will shrink by 5%. A builder lets the block of
wood shrink. He wants to use it to fill a gap that measures 3.5 inches wide.
How much does the builder need to cut off the wood block so that it will fit exactly in the gap? Enter the answer in the box.
Answer:
He will have to cut off 1.25 inches.
Step-by-step explanation:
Take 5% of 5 inches
0.05(5)=0.25 inches
5 inches - 0.25 inches= 4.75 inches
4.75 inches is how wide the wood is after it shrinks.
Find how much he needs to cut off
4.75 inches - 3.5 inches=1.25 inches
He will need to cut off 1.25 inches in order for the block to fit exactly.

Answer:
a) 540°
b) 720°
c) 900°
d) 1440°
Step-by-step explanation:
The total measure of internal angles of a convex polygon is given by the formula ...
sum of angles = 180°(n -2) . . . . for an n-sided polygon
So, you count the sides, subtract 2, and multiply that result by 180°.
__
a) 180°(5 -2) = 540°
b) 180°(6 -2) = 720°
c) 180°(7 -2) = 900°
d) 180°(10 -2) = 1440°
A study was conducted by a certain firm to determine who curses at their computer. The results indicated that 30% of people age 18-34 years have cursed at their computer. What are the odds against a randomly selected 18- to 34-year old having cursed at his or her computer. LOADING... Click the icon to view an explanation of odds. The odds, in the most simplified form, are nothing to nothing against a randomly selected 18- to 34-year old having cursed at his or her computer. (Type whole numbers.)
Answer:
The odds, in the most simplified form, are 7 to 3 against a randomly selected 18- to 34-year-old having cursed at his or her computer.
Step-by-step explanation:
Given
[tex]p = 30\%[/tex] ---- proportion that cursed their computer
Required
Odds against the selected
Using the complement formula, the proportion that the selected has not cursed at their computer is:
[tex]p' = 1 - p[/tex]
[tex]p' = 1 - 30\%[/tex]
[tex]p' = 70\%[/tex]
So, the odds against the selected is:
[tex]Odds = p' : p[/tex]
[tex]Odds = 70\% : 30\%[/tex]
Divide by 10%
[tex]Odds = 7: 3[/tex]
