Answer:

Total volume of the figure = 1067 cm³

Step-by-step explanation:

Volume of the composite figure = Volume of the rectangular prism + Volume of the square pyramid

Volume of the rectangular prism = Length × Width × Height

                                                      = 10 × 10 × 7

                                                       = 700 cm³

Volume of the square pyramid = \frac{1}{3}(\text{Area of the base})\times (\text{height})

                                                   = \frac{1}{3}(\text{Side})^2 × height

                                                   = \frac{1}{3}(10)^2(18-7)

                                                   = 366.67 cm³

Total volume of the composite figure = 700 + 366.67 = 1066.67 cm³

                                                                                          ≈ 1067 cm³

Which equation has a constant of proportionality equal to 1? A. y=10/11x B. y= 7/8x C. y= 3/15x D. y=x
shtirl [24]

An equation is said to have a constant of proportionality if 'x' is a multiple of 'y' or 'y' is a multiple of 'x'.

Now, we have to determine an equation with constant of proportionality as '1'.

1. y = \frac{10}{11}x

This equation has constant of proportionality as '\frac{10}{11}'.

2. y = \frac{7}{8}x

This equation has constant of proportionality as '\frac{7}{8}'.

3. y = \frac{3}{15}x

This equation has constant of proportionality as '\frac{3}{15}'.

4. y = x

This equation has constant of proportionality as '1'.

Option D is the correct  answer.

Use △XYZ, in which ∠X is a right angle and tanY=815.
Neporo4naja [7]

Answer:

8/17

Step-by-step explanation:

The correct and complete question is:

<em>Use △XYZ, in which ∠X is a right angle and tanY=8/15. What is the ratio for sinY?</em>

From definition:

tan(Y) = opposite/adjacent

From the graph and the question:

tan(Y) = XZ/XY = 8/15

Then:

XZ = 8 and XY = 15. Using pytaghorean theorem:

XZ² + XY² = YZ²

8² + 15² = YZ²

√289 = YZ

17 = YZ

From definition:

sin(Y) = opposite/hypotenuse

From the graph:

sin(Y) = XZ/YZ

sin(Y)= 8/17

Can some one help me please....<br><br>step by step explanation........ ​
ElenaW [278]

Answer:

There are 77 members in the group.

Step-by-step explanation:

1Rs = 100 paise ( Indian Currency Conversion )

Given,

Total amount collected is = Rs 59.29

Now convert Rs 59.29 to paise that is 59.29 × 100 = 5929 paise

Condition :- Paise collection = Total number of members

Consider any of the above condition as X

So, X² = 5929

X = √5929 = 77

Thus, Total number of members in the group is 77 [ Option C ]

Hope this helps you.
