Answer:

x = 61

Step-by-step explanation:

The two angles add to a right angle, which is 90 degrees

29+x = 90

Subtract 29 from each side

29+x-29 = 90-29

x = 61

Answer:

61 degrees

Step-by-step explanation:

if Y is 29 degrees and the entire angle is a 90 degree angle than x would be 61 degrees to equal a 90 degree angle

Answer:

113.04

Step-by-step explanation:

To find the area of a circle from the radius, you square the radius (r*r, or in this case, 6*6) and then multiply by pi.  You end up with 36*3.14 or, 113.04.

Answer:

The continuous closed line that makes the boundary of a two-dimensional shape is known as the perimeter. It’s easy to work out the perimeter of a shape with straight edges, such as a square, because you simply add the lengths of each edge together. A different formula is required to work out the perimeter of a semi circle (a circle cut in half), because it consists of a curved edge as well as a straight edge. That formula is

Step-by-step explanation:

P = \frac{1}{2} πd + dP=

πd+d

where ​d​ is the diameter of the semi circle.

Pi is a circle's circumference divided by its diameter and is always the same value, 3.14.

since hour is the denominator, it would be set up as 2/3 / 1/12, which is 24/3 which is also 8, per ''hour'' after per is deno

Step-by-step explanation:

Answer:

8 mph

Step-by-step explanation:

If Lien jogged 2/3 of a mile in 1/12 of an hour and you need to find how far she went in 1 hour, you would multiply 2/3 by 12 because thats how far she jogged in 1/12 of an hour.

So, 2/3 times 12 equals 8.

This is what a histogram is

Pls give brainliest and thanks

Histogram, because a large number of scores are reported as ranges. The correct option is A.

The graphic representation of data points arranged into user-specified ranges is called a histogram. The histogram, which resembles a bar graph in appearance, condenses a data series into an intuitive visual by collecting numerous data points and organizing them into logical ranges or bins.

Given that a group of 23 students participated in a math competition. Their scores are below:

Score (points)          Number of Students

20- 29                                   4

30 – 39                                 7

40 – 49                                 5

50 – 59                                 4

60 – 69                                 3

If the above data is large data then it will be represented by the histogram. Therefore, the correct answer is A because of the histogram, because a large number of scores are reported as ranges. The correct option is A.

Answer:

1. 30% 2. 160 square feet

Step-by-step explanation:

1.The entire area of the garden is 20x16=320 square feet

The area of the Zinnias(including roses) is 8x12 = 96 square feet

To get the percent, we have to divide the smaller number by the bigger number and multiply by 100, like 96/320x100=30%

2. The width progresses in the first rectangle by four 8 to 12, then again by four 12, 16 and again by four 16 to 20, which means that the next rectangle would have a width of 20+4=24. Doing the sale analysis for the height, we get that the increase is with 4 feet at a time or the new rectangle would have a width of 24 and height of 20, which means a total area of 480 feet. We would have to subtract all other rectangles and the new area would be 480 - (20x16) = 160 square feet

y=7

Answer:

12

Step-by-step explanation:

Okay, so on a grid, points Q and R are parallel to each other on the point 6, we just have to figure out how far apart they are, and to figure that out, we have to find the distance between 8 and -4 so:

8 - -4 = 8 + 4 = 12

So, the distance from point Q to point R is 12

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

since we know the Hyp and the Opp of the angle  pick SOH

Sin(Ф)= 42 / 42[tex]\sqrt{2}[/tex]

∅ = arcSin( 42 / 42[tex]\sqrt{2}[/tex] )

∅ = 45 °

Answer:

29: 81.5

30: 9

31: 180

Step-by-step explanation:

29: if c=9 then squared then it is 9 times 9 which equals 81 then a equals 1/2 which is 0.5 in fraction so we add 81 + 0.5 =81.5

30: c equals 9 which we times by 2 and equals 18 then we times 18 by a which is 0.5 and it goes back down to 9

31: b equal 15 and it is squared so we times 15 by 15 which equals 225 and then we multiply 5 times c and c is 9 so 5 times 9 is 45 and 225 minus 45 equals 180

Answer:

A = 37 degrees ; B = 82 degrees

Step-by-step explanation:

the angle A plus 143 must measure 180 degrees

angle A = 180 - 143 = 37 degrees

the sum of the inner angles of a triangle is 180 degrees

A + B + C = 180

37 + B + 61 = 180

B = 180 - 98 = 82 degrees

Answer:

(D) 81 feet      

Step-by-step explanation:

From the figure drawn, it is given that AB is parallel to DE, in ΔABC and ΔCDE, we have

∠BAC=∠DEC(Alternate angles)

∠ACB=∠DCE(Vertically opposite angles)

Thus, by AA rule, ΔABC is similar to ΔCDE.

Since the line connecting from the whales to the sharks is parallel to the line connecting from the penguins to the fish tanks, the triangles shown in the figure are similar. Using the property of similar triangles.

Answer:

4/6 or 2/3

Step-by-step explanation:

1/2 of the die is odd numbers so, you would add one more number which would be 4/6 or 2/3

The probability of rolling 2 or an odd number is 2/3.

"Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one".

For the given situation,

Rolling a die s = {1,2,3,4,5,6}

⇒[tex]n(s)=6[/tex]

The event a is rolling 2 = {2}

⇒[tex]n(a)=1[/tex]

Probability of rolling 2, [tex]p(a)=\frac{n(a)}{n(s)}[/tex]

⇒[tex]p(a)=\frac{1}{6}[/tex]

The event b is rolling an odd number = {1,3,5}

[tex]n(b)=3[/tex]

Probability of rolling an odd number, [tex]p(b)= \frac{n(b)}{n(s)}[/tex]

⇒[tex]p(b)=\frac{3}{6}[/tex]

Thus probability of rolling 2 or an odd number = [tex]p(a)+p(b)[/tex]

⇒ [tex]\frac{1}{6} + \frac{3}{6}[/tex]

⇒[tex]\frac{4}{6}[/tex]

⇒[tex]\frac{2}{3}[/tex]

Hence we can conclude that the probability of rolling 2 or an odd number is 2/3.
