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

someone please answer this!!
Answer:
4m is the answer.
Step-by-step explanation:
a = 3m
b = ?
c = 5m
According to the Pythagoras theorem,
a² + b² = c²
3² + b² = 5²
9 + b² = 25
b² = 25 - 9
b² = 16
b = 4m
∴ The distance between the ladder and the bottom of the slide is 4m.

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
Thus, the area of the sector is 76. 95 m

Carla knows that, in order to use adjectives and adverbs more effectively, she needs to understand comparison. Which concepts below can help Carla expand her knowledge?
Each degree of comparison has its own suffix
The positive degree of comparison simply modifies the word and has no suffix
The comparative degree compares two things and uses the suffix –est
The superlative degree compares three things and uses the suffix -est
Answer:
Each degree of comparison has its own suffix..
Both the adjectives and adverbs are used to make comparisons. The comparatives and superlatives are also used in writing to hedge or to boost the language. Each degree of comparison has its own suffix. The correct option is A.
What is comparative degrees?The comparative form is used to compare two people, ideas or things. The superlative form with the word 'the' is used to compare three or more. The comparative adjectives are used to compare differences between the two objects they modify (larger, smaller, faster, higher).
The comparative form is used in the sentence where two nouns are compared. The comparative adjectives compare one person or the thing with another and enable us to say whether a person or thing has more or less of a particular quality.
One example of comparative adjective is that Josh is taller than his sister.
Thus the correct option is A.

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?
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.
The height of six trees in a parkway are 5 meters, 8 meters, 12 meters, 6 meters, 11 meters, and 5 meters. Find the mean height of the six trees. A. 7 meters B .7.83 meters C.8.21 meters D.12 meters
Answer:
The answer is B, 7.83 meters.
Step-by-step explanation:
The mean of the six trees refers to the average height of all six trees. To find the mean value of any set of values, simply follow this formula:
Mean = [tex]\frac{Sum of all values}{Number of values you used}[/tex]
So for this particular question, my working was:
Mean = (5m + 8m + 12m + 6m + 11m + 5m)/6 = 7.833333333333m (Round off to 3 significant figures to get 7.83m)
Using the diagram, calculate the values of the unknown variables: a, b, and c.
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

Answer:
0 (option a)
Explanation:
for a number to be divisible by 5, it has to end with the digits 0 or 5. for a number to be divisible by 3, the sum of all its digits has to be divisible by 3.
for 63215: 6 + 3 + 2 + 1 + 5 = 17 (not divisible by 3)
for 63210: 6 + 3 + 2 + 1 + 0 = 12 (divisible by 3)
thus, the missing digit is 0.

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
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
