reciproque de pytaghore to solve AC

Answer:

DCB=33

Step-by-step explanation:

We are given the angle for a and we know the angle for ADC is 90 because AB & DC are perpendicular.  Given two angles of a triangle we can find the third by subtracting the two known values from 180 because we know a triangle totals 180.

180-33-90=57

So we can also find CDB because we know AB & DC are perpendicular.  It is also 90 because two perpendicular lines make a 90 angle.  

DCB can be found because we know that ACB makes a 90 angle and the ACD portion is 57.  So we subtract 57 from 90.

90-57=33

We can also find CBD by subtracting CDB and DCB from 180.

180-90-33=57

Answer:

a = 8

Step-by-step explanation:

(x+8)(x+1) = x^2 + 9x + 8

Answer:

18 is equivalent to 3/24 because 1 x 24 = 8 x 3 = 24. 216 is equivalent to 3/24 because 2 x 24 = 16 x 3 = 48.

0.125

3/24 as a decimal is 0.125.

Answer:

0.89417

Step-by-step explanation:

Using the relation to obtain the Zscore :

Z = (x - mean) ÷ standard deviation / sqrt(n)

x = 0.8535

Mean = 0.8565

Standard deviation = 0.0518

Sample size, n = 465

P(x ≤ 0.8535) = (0.8535 - 0.8565) ÷ 0.0518/sqrt(465)

P(x ≥ 0.8535) = - 0.003 / 0.0024021

P(x ≥ 0.8535) = - 1.249

P(Z ≥ - 1.249) = 0.89417

Answer:

The answer is A.      4+y^2/2y^2

Answer:

675.1 sq m

Step-by-step explanation:

Area of larger circle = 3.14(24^2) = 3.14(576) = 1808.64

area of smaller circle = 3.14(19^2) = 3.14(361) = 1133.54

area of ring = Area of larger circle - area of smaller circle

= 1808.64 - 1133.54 = 675.1

you need to see all the measurements to know what m∠5 to get the answer.

Answer:

28.84

Step-by-step explanation:

the figure is just a square made up of squares so to find the side of a square you use the \sqrt{52} to find one side then multiply times 4 for each side

Answer:

(√6x√20) / √3 = 2√10

Step-by-step explanation:

hello :

(√6x√20) / √3 =√2x√3 x√4x√5 / √3

because : √6 = √2x√3 and √20= √4x√5 = 2x√5

now simplify by √3 :(√6x√20) / √3 =√2x2x√5

(√6x√20) / √3 = 2√10 so : a =2 and b =10

Answer:

$32.60

Step-by-step explanation:

Remember to find the percentage of something, times the number by the percentage, which is two decimals to the left. So 15% would be 0.15.

The total is unknown so replace it with a variable, such as x

.15(x)=4.89

Isolate x by dividing both sides by 0.15

x=32.6

Meal price: $32.60

Check your answer by multiplying this number by the tip percentages

32.6(.18)=5.87

32.6(.20)= 6.52

Answer:

164.93 I believe is the answer

Answer:

24) $230.45

Step-by-step explanation:

25%=25/100=0.25

0.25*357.35=89.38 (rounded to the nearest hundredth)

357.35-89.38=267.97

Now, we have the 25% discount, it is the same thing for the 14% discount.

14%=14/100=0.14

267.97*0.14=37.52(rounded to the nearest hundredth again)

267.97-37.52=230.45

Therefore, total cost is $230.45

Q: How might doing math slowly help with problems that are difficult to understand or hard to solve?

A: It calms you down. When you are stressed, you are most likely to get it wrong because you are panicking. This also helps because you can read the problem correctly and make sure you are doing it right, because in math, If you get 1 small thing wrong, you usually get the entire thing wrong.

I hope this helped!
