Use the law of cosines:
Distance = square root( 14^2 + 19^2 -2(14)(19) x cos(30)
Distance = 9.8 yards.
The answer is A.
The correct answer is A. 9.8 yds is the distance between two receivers.
The Law of Cosines states that for any triangle with sides a, b aand c , and angle [tex]\( \theta \)[/tex] opposite side c, the following equation holds:
[tex]\[ c^2 = a^2 + b^2 - 2ab\cos(\theta) \][/tex]
We want to find d, which corresponds to c in our scenario. Plugging in the values we have:
[tex]\[ d^2 = a^2 + b^2 - 2ab\cos(\theta) \] \[ d^2 = 14^2 + 19^2 - 2 \cdot 14 \cdot 19 \cdot \cos(30^\circ) \][/tex]
Since [tex]\( \cos(30^\circ) = \sqrt{3}/2 \)[/tex], we can substitute this value into the equation:
[tex]\[ d^2 = 14^2 + 19^2 - 2 \cdot 14 \cdot 19 \cdot \frac{\sqrt{3}}{2} \] \[ d^2 = 196 + 361 - 14 \cdot 19 \cdot \sqrt{3} \] \[ d^2 = 557 - 266 \cdot \sqrt{3} \][/tex]
Now we can solve for d:
[tex]\[ d = \sqrt{557 - 266 \cdot \sqrt{3}} \][/tex]
Calculating this value gives us [tex]\( d \approx 9.8 \)[/tex] yards to the nearest tenth of a yard.
Therefore, the two receivers are approximately 9.8 yards apart.

We know that we need a factorization that multiplies to -18, and adds up to positive 7. Test all our combinations! Add them together and see if they equal 7.
-18 + 1 = -17 ≠ 7
-1 + 18 = 17 ≠ 7
-9 + 2 = -7 ≠ 7

Find the hypotenuse (2) of the right triangle.
Round your answer to the nearest tenth.
7 m
11 m
A
8.5 m
B
18 m
(
23 m
D
13 m
Answer:
D) 13m
Step-by-step explanation:
To find the hypotenuse, use the formula for a² + b²= c², where a and b are the values of the triangle's two legs and c is the value of the hypotenuse.
In this case, a² = 7m and b² = 11m. Remember that there is no definite value for a or b, so they can be switched around.
So now our formula will look like this: 7² + 11² = c².
When squaring the two values, you will get a more simplified manner of the equation: 49 + 121 = c².
When we add them altogether, we get 170 = c²
That is not our answer yet, because we want the simplified, and not squared, form as the answer.
In order to do that, we must find the square root of √170, which is 13.0384048104, or just 13 when rounded to the nearest tenth.
So now we know that c², the hypotenuse, is approximately equal to 13.
Just to be sure, plug in all the value into the formula and try again.
7² + 11² = 13². 49 + 121 = 169 170 ≈ 169Notice: the reason why they are not both is because we rounded 13.0384048104 to 13. But if we square 13.0384048104, we get 170, which is the same value as the one above. Easy, right?

Ashley is packing her bags for her vacation. She has 7 unique socks, but only 3 fit in her bag.
How many different groups of 3 socks can she take?
Answer:
There are 35 possible group of 3 socks from a total of 7
Step-by-step explanation:
Given
Number of unique socks = 7
Number of possible selection = 3
Required
Number of ways she can make her selection.
The question can be categorised as combination; reason being that words like "take" as used in the question points to combination or selection.
To solve this, we make use of combination formula.
nCr = nPr/r!
Where n = 7 and r = 3
By substitution, we have
7C3 = 7P3÷3!
Taking it one at a time
7P3 = 7!÷(7-3)!
7P3 = 7! ÷ 4!
7P3 = 7 * 6 * 5 * 4! ÷ 4!
7P3 = 7 * 6 * 5
7P3 = 210
3! = 3 * 2 * 1
3! = 6.
So,
7C3 = 210 ÷ 6
7C3 = 35.
Hence, there are 35 possible group of 3 socks from a total of 7

Time, t = 3.125 s
Step-by-step explanation:
The height attained by the ball after it was kicked is given by as a function of time t as :
[tex]h=-16t^2+50t[/tex]
It is required to find the time until which the ball hits the ground. At that point, h(t) = 0

Answer:
75 men spent 7 hours or more exercising.
Step-by-step explanation:
If you multiply 300 by 0.67, you get 201. That would be the amount of men. Multiply 300 by 0.37 to get 111, the amount of people who spent less than 7 hours exercising, and subtract it from the 201 men to get 90. Then, multiply 300 by 0.75 to get 225, the amount of women that spent 7 hours or more exercising, and subtract it from 300, which would result in an answer of 75. That's how many men spent 7 hours or more exercising.
There are 90 picking days in a season. A farms picks approximately 8 x 104 papayas
each day. Approximately, how many papayas are picked each season?
Answer:
74880
Step-by-step explanation:
first you do 8x104 and get 832 and then you do 832x90 and you get 74880.
By performing multiplication, you find that a farm picking approximately 800,000 papayas each day for 90 days in a season would pick around 72,000,000 papayas in total.
Explanation:The subject of this question is Mathematics, specifically multiplication. To determine the total number of papayas picked in a season, we can multiply the number of picking days in a season by the average number of papayas picked each day. Thus, we need to multiply 90 (the number of picking days in a season) by 8 x 104 (the average number of papayas picked each day). Step-by-step, this process would look like the following:
Convert 8 x 104 to its standard form, which is 800,000. This represents the number of papayas picked each day. Multiply 800,000 papayas by 90 days. 800,000 papayas/day * 90 days = 72,000,000 papayas.
Therefore, the farm picks approximately 72,000,000 papayas in a season.

Pete was able to map quadrilateral A, B, C, D onto E, F, G, H using a translation and a dilation. Pete concluded: "I was able to map quadrilateral A, B, C, D onto
E, F, G, H using a sequence of rigid transformations, do the figures are congruent." What
error did Pete make in his conclusion?
Answer:
Pete didn't use only rigid transformations, so the figures are not congruent
Step-by-step explanation:
Translations, reflections, and rotations are all rigid transformations while a dilation is not. Pete used a dilation to make the shape smaller after transforming it, therefore the shape is similar not congruent.
If you're confused with what these math terms mean:
A rigid transformation (also called an isometry) is a transformation of the plane that preserves length.
In geometry, a reflection is a type of rigid transformation in which the preimage is flipped across a line of reflection to create the image. Each point of the image is the same distance from the line as the preimage is, just on the opposite side of the line.
A dilation is a type of transformation (not a rigid one though) that changes the size of the image. The scale factor, sometimes called the scalar factor, measures how much larger or smaller the image is.
Transformation involves moving an object from its original position to a new position.
Rotation is a transformation that turns a figure about a fixed point called the center of rotation. An object and its rotation are the same shape and size, but the figures m
Pete's mistake in his conclusion is that he stated the quadrilaterals were congruent when he used a sequence of transformations that included a dilation. Dilation changes the size of the figure while maintaining shape, thus the shapes are similar but not congruent.
Explanation:In his conclusion, Pete made an error by stating that the quadrilaterals A, B, C, D, and E, F, G, H are congruent because he used a sequence of rigid transformations. However, transformations that include a dilation are not rigid transformations. Rigid transformations, such as rotations, reflections, or translations, preserve the shape and size of the figure, making the resulting figure congruent to the original. A dilation, however, changes the size of the figure while maintaining its shape, resulting in a figure similar to, but not congruent with, the original. Therefore, although Pete was able to map quadrilateral A, B, C, D onto E, F, G, H, the two shapes are not congruent because dilation was a part of the sequence of transformations he used.

Data Presentation - Tables
Tables are a useful way to organize information using rows and columns. Tables are a versatile organization tool and can be used to communicate information on their own, or they can be used to accompany another data representation type (like a graph). Tables support a variety of parameters and can be used to keep track of frequencies, variable associations, and more.
For example, given below are the weights of 20 students in grade 10:
50, 45, 48, 39, 40, 48, 54, 50, 48, 48, \\ 50, 39, 41, 46, 44, 43, 54, 57, 60, 45.
50,45,48,39,40,48,54,50,48,48,
50,39,41,46,44,43,54,57,60,45.
To find the frequency of 4848 in this data, count the number of times that 4848 appears in the list. There are 44 students that have this weight.
The list above has information about the weight of 2020 students, and since the data has been arranged haphazardly, it is difficult to classify the students properly.
To make the information more clear, tabulate the given data.
