What is the length of the missing leg?
someone help please
Answer:
7.76
Step-by-step explanation:
tan 29° = XY/14
XY = tan 29° (14)
= 7.76
Answer:
XY=7.76
Step-by-step explanation:
Tan25° says opp÷adj
so it's Tan29°=XY÷14
then multiply both sides by 14 to make CY the subject of the formula...
14×Tan29°=XY
therefore=XY=7.76
Jimmy's Bakery sold 950 donuts last week. This week , the number of donuts sold increased 12%. How many more donuts were sold this week?
On a certain hot summer's day, 336 people used the public swimming pool. The daily prices are $1.50 for children and $2.50for adults. The receipts for admission totaled $613.00 How many children and how many adults swam at the public pool that day?
Let c represent the number of children ($1.75 each) and a represent the number of adults ($2.00 each).
We know that there were 340 people total, so c + a = 340. This implies that a = 340 - c
We also know that $1.75 c + $2.00 a = $609.25
By substituting a with 340 -c we have $1.75 c + $2.00 (340 -c) = $609.25
Use the distributive property to obtain $1.75 c + $680 - $2.00 c = $609.25
Subtract $680 from both sides and combine like terms to get - $0.25 c = - $70.75
Now, divide both sides by -$0.25 to get c = 283, the number of children.
The number of adults is 340 - c or 340 - 283 = 57
Answer:
227 children and 109 adults
Step-by-step explanation:
227*1.5+109*2.5=613
227+109=336

I really need help!!!!!!!
Answer:
x=10 3x= 30
Step-by-step explanation:
3x = 30 since the angles are vertical angles
3x/3 = 30/3
x = 10
Answer:
B
Step-by-step explanation:
Set up an equation:
30 = 3x
Divide both sides by 3:
10 = x
x = 10 degrees
Plug the value of x into the angle:
3 × 10
30 degrees
A magazine collects these data measuring the battery life , in hours , of a sample of MP3 players : 5.7, 6, 6.1, 6.5, 6.8, 7.1, 7.4, 7.6, 8.1, 8.2 About how long does an MP3 player in the 50th percentile play ?
Answer:
the answer is 6.8
Step-by-step explanation:
The computation is shown below:
Since we have to determined the 50th percentile play
So,
= 50(nth value) ÷ number of observations
= 50(nth value) ÷ 10
= 5th value
= 6.8
Hence the answer is 6.8

What is the sum of interior angles of a 53-gon? Type just the number, no words, letters, or symbols
Answer:
S = 9180°
Step-by-step explanation:
Given the following data;
Number of sides = 53
To find the sum of interior angles of a 53-gon;
Mathematically, the sum of the interior angles in a regular polygon is given by the formula;
S = 180(n - 2)
Where;
n is the number of sides.
S is the sum of the interior angles
Substituting into the formula, we have;
S = 180(53 - 2)
S = 180 * 51
S = 9180°

Rishan is building a number 3091 using Place-value blocks. There are no thousands block. How many hundreds blocks can he use instead?
Given:
The number is 3091.
To find:
The number of hundreds blocks if there are no thousands block.
Solution:
The given number is 3091.
It can be written as:
[tex]3091=3000+0+90+1[/tex]
[tex]3091=3\times 1000+0\times 100+9\times 10+1\times 1[/tex]
[tex]3091=3\ Thousands+0\ Hundreds+90\ Tens+1\ Ones[/tex]
There are no thousands block. So,
[tex]3000=30\times 100[/tex]
[tex]3000=30\ Hundreds[/tex]
Therefore, the number of hundreds blocks in 3091 is 30.

Option D represents a data set with a lower quartile of 24 and an upper quartile of 42.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
Quartiles are then selected as 3 points such that they create four groups in the data, each group approximately possessing 25% of the data.
The lower quartile, also called the first quartile has approx 25% in its left partition, and on its right lies approx 75% of the data.
Similarly, the second quartile (also called median) is approximately in mid of the data.
The third quartile has approx 75% in its left partition, and on its right lies approx 25% of the data.
Left to right is said in the assumption that data were arranged increasingly from left to right
Hence, the box plot that represents a data set with a lower quartile of 24 and an upper quartile of 42 from the given option is D.

x^2=6x+1
rewrite the equation by completing the square your equation should look like (x+a)^2=b or (x-c)^2=d
What are the solutions to the equation?
Answer:
x=3+√10 or x=3−√10
Let's solve your equation step-by-step.
x2=6x+1
Step 1: Subtract 6x+1 from both sides.
x2−(6x+1)=6x+1−(6x+1)
x2−6x−1=0
For this equation: a=1, b=-6, c=-1
1x2+−6x+−1=0
Step 2: Use quadratic formula with a=1, b=-6, c=-1.

This season, the probability that the Yankees will win a game is 0.6 and the probability that the Yankees will score 5 or more runs in a game is 0.57. The probability that the Yankees lose and score fewer than 5 runs is 0.34. What is the probability that the Yankees would score fewer than 5 runs when they win the game? Round your answer to the nearest thousandth.
The probability that the Yankees would score fewer than 5 runs when they win the game is 0.204 if the probability that the Yankees will win a game is 0.6
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
The probability that the Yankees will win a game P(win) = 0.6
The probability that the Yankees will score 5 or more runs in a game is:
P(s>5) = 0.57
The probability that the Yankees lose and score fewer than 5 runs is:
P(s<5) = 0.34
To find the probability that the Yankees would score fewer than 5 runs when they win the game:
This is the case of probabilities of one event and another event together we will multiply the respective probabilities of the event:
= P(win)×P(s<5)
= 0.6×0.34
= 0.204
Thus, the probability that the Yankees would score fewer than 5 runs when they win the game is 0.204 if the probability that the Yankees will win a game is 0.6

Find the roots of the following function:
y = x2 − 7x − 30
Answer:
x = 3, −10

How do you write 0.0006363 in scientific notation?
Answer:
Step-by-step explanation:
Proper scientific notation means that there is only 1 number to the left of a decimal and everything else to the right of it. Also, because the number is initially less than 1, the exponent will be a negative one. We have to move the decimal 4 places to the right in order to get the 6 to the left of it, so in correct scientific notation format, we have

find the surface area asap i’ll give brainliest
Answer:
The surface area of the prism is 544 in²
Step-by-step explanation:
Given;
base of the triangular prism, b = 12 in
side length, = 10 in and 14 in
height = 8 in
The surface area is calculated as follows;
S.A = 2(area of the triangular face) + area of the rectangualr faces
S.A = 2( ¹/₂ x 12 x 8) + 2(14 x 10) + 14 x 12
S.A = (96) + 2(140) + (168)
S.A = 96 + 280 + 168
S.A = 544 in²
Therefore, the surface area is 544 in²

Find the probability that a student earns a
grade of B.
p = [?]
Enter a decimal rounded to the nearest hundredth.
Answer:
0.29
Step-by-step explanation:
Total grade frequency = (5 + 10 + 15 + 3 + 2) = 35
Frequency of grade B = 10
Probability = required outcome / Total possible outcomes
Required outcome = frequency of grade B = 10
Total possible outcomes = total grade frequency = 35
P(B) = 10 / 35
P(B) = 0.2857
P(B) = 0.29

Ana ganha 1200,00 reais em seu trabalho, se ela gastar um quinto em comida e dois terços do que sobrar em aluguel, quanto sobra, ou falta?
Answer:
Ana fica com a quantia de 560
Step-by-step explanation:
Dado
Ana ganha = 1200
Ela gasta um quinto com comida e dois terços do que resta com o aluguel
Valor que sobrou com Ana depois de gastar com comida e aluguel
1200 - 1/5 (1200) - 1/3 (1200)
1200 - 240 -400
1200 -640
560
Ana fica com a quantia de 560

13.2 Area of Triangles
2. Find the area of the triangle.
14 ft
17 ft
Answer:
119
Step-by-step explanation:
Answer:
question 1 is, the area is 119
question two is, the base length is 18
Step-by-step explanation:
PART ONE
To figure this out we need to know that to find the area the equation is A=1/2bh so lets create our equation
A=1/2(17)(14)
A=1/2(238)
A=119
119 is your area
PART TWO
to find out the length we need to basically reverse what we did in the first part
270*2=540
540 divided by 30 (the height)=18
18 is the base length
to show it is correct we can use these numbers to find the answer
A=1/2(18)(30)
A=1/2(540)
A=270
Triangle XY Z has vertices X = (5, -1), Y = (1, 4), and Z=
(-8,0). Triangle X'Y'Z' is formed when triangle XYZ is
reflected over the y-axis. What are the coordinates of
triangle X'Y'Z'?
Answer:
see explanation
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y ) , then
X (5, - 1 ) → X' (- 5, - 1 )
Y (1, 4 ) → Y' (- 1, 4 )
Z (- 8, 0 ) → Z' (8, 0 )
