For each question we must apply the Pythagorean theorem and clear the value of x.
question 5
x = root (14 ^ 2 + 16 ^ 2)
x = root (452)
x = 2raiz (113)
question 6
x = root (8 ^ 2 + 15 ^ 2)
x = 17
question 7
x = root (12 ^ 2 + 12 ^ 2)
x = root (2 * (12 ^ 2))
x = 12raiz (2)
question 8
x = root (18 ^ 2 - 9 ^ 2)
x = root (243)
x = 9raiz (3)

The length of a rectangle is three times its width. If the perimeter is at most 128cm, what is the greatest possible value for t

anastassius [24]

Answer:

16 cm

Step-by-step explanation:

Let the width be x

The length will be 3 x since the length is three times the width

Perimeter=2(l+w) where l is length and w is width

By substituting 128 cm for perimeter, x for w and 3 x for l then

128=2(3x+x)

128=8x

$x=\frac {128}{8}=16$

Therefore, the width is 16 cm, the width is 16*3=48 cm

I REALLY NEED HELP PLEASE!!

nadezda [96]

Answer:

To me the triangles in #6 appear to be the same shape as the first triangle in #7(EFG) with different lengths on the sides. But not much else is the same. I mean they are all triangles but the shape of the second triangle in #7(XYZ) isn't the same as either of the triangles in #6.

I hope that made sense to you!

Hope this helped! Have a great day! :)

Find m∠U.<br> Write your answer as an integer or as a decimal rounded to the nearest tenth.

AleksAgata [21]

Answer:

50.2

Step-by-step explanation:

$ut = \sqrt{ {6}^{2} + {5}^{2} } \\ \sqrt{36 + 25} \\ \sqrt{61 } \\ using \: cosine \: rule \\ cos \: u = \frac{ {5}^{2} + 61 - 36 }{2 \times 5 \times \sqrt{61} } \\ \\ = \frac{25 + 61 - 36}{78} \\ \\ = \frac{50}{78 } \\ \cos \: u = 0.64 \\ m \:u = 50.2$

Pose a question for which a two-way table is appropriate. Be creative here!

arlik [135]

Define an issue that is important to you (politics, medicine, social media, education, etc.), and think about some things you might want to know about this issue. Briefly explain your issue and what you hope to learn or understand. Pose a question for which a two-way table is appropriate. Be creative here! Collect data from at least 20 people (or other sources). Display your data in a two-way frequency table like the one shown below. Your table can have more rows or columns if you need them. I am not quite sure of what the question is supposed to be.
