1. In the diagram below, the length of the legs AC and BC of right triangle ABC are 6 cm and 8 cm,
respectively. Altitude CD is drawn to the hypotenuse of AABC. What is the length of AD to the nearest tenth
of a centimeter?

Answers

Answer 1

Answer:

Note  that  ABC   is  a 6 - 8 -10   right triangle  with AB  = 10

 

Also note  that triangle ADC  is similar to triangle  ACB

 

Therefore

 

AD/ AC =  AC / AB       so

 

AD / 6  = 6/ 10           cross-multiply

 

10*AD  =  6 * 6

 

810*AD   = 36

 

AD  = 36 /  10  =    3.6  =  x

I hope this helps a little bit.

An ANOVA procedure is applied to data obtained from 6 samples where each sample contains 10 observations. The degrees of freedom in the denominator for the critical value of F test statistic is Group of answer choices

Answers

Answer:

The degree of freedom in the denominator = 114

Step-by-step explanation:

For Analysis of Variance procedure :

The number of groups, k is the number of distinct groups = 6

The total number of samples, N = number of groups multiplied by the number of samples per group ; N = 20 * 6 = 120

Degree of freedom (df) :

dfwithin = df of numerator = k - 1 = 5

df between = df of denominator = N - k

df denominator = 120 - 6 = 114

Using the diagram, calculate the values of the unknown variables: a, b, and c.

Answers

Answer:

a = 82

b = 130

c = 118

Step-by-step explanation:

A quadrilateral is inscribed in a circle. So, it is a cyclic quadrilateral.

Opposite angles of a cyclic quadrilateral are supplementary.

Therefore,

a° + 98° = 180°

a° = 180° - 98°

a° = 82°

a = 82

By inscribed angle theorem:

a° = 1/2(b° + 34°)

82° * 2 = b° + 34°

164° - 34° = b°

b° = 130°

b = 130

Again by inscribed angle theorem:

76° = 1/2(c° + 34°)

76° *2 = c° + 34°

152° - 34° = c°

c° = 118°

c = 118

So, for the square:

A = Length • Width
A = 8•8
A = 64

Then, for the triangle:
A = 1/2 • Base • Height
A = 1/2 • 6 • 8
A = 3 • 8
A = 24

Finally:
64 + 24 = 88

Charlotte thinks of a number.
She increases it by one fifth, and then reduces that answer by one half.
She finishes with 39.
What number did she start with?

Answers

Answer:

Charlotte started with 65.

Step-by-step explanation:

In order to find what number Charlotte started with, we need to go backward. So first, multiply by 2, then multiply by 5/6. 39 multiplied by 2 is 78, which is 6/5 of the number Charlotte started with. So what we need to do is multiply 78 by 5/6. That equals 390/6, which is 65. The problem has been solved. Charlotte started with 65.

Find the area of the smaller sector round to the nearest tenth. Need help fast!!

The area of the sector is  76. 95 m

How to determine the area of a sector

Using the formula;

Area of  sector of a circle  = /360° (r2)

where r is the radius of the circle

is the angle of the sector

From the diagram,

= 77°

r = 10. 7m

= 3. 142

Substitute into the formula

Area of the sector = 77/ 360° * (3. 142* 10. 7 * 10. 7)

Area of the sector = 0. 2139 * 359. 72

Area of the sector = 76. 95 m
