Solve 4.85 ÷ 5 = ___. 0.94 0.95 0.96 0.97

Answer:

KRM = 44 degrees, MRD = 46 degrees

Step-by-step explanation:

This angle is a right angle so it equals 90 degrees. That means that equations 3g + 29 and 7g + 11 will amount to 90 degrees.

(3g + 29) + (7g + 11) = 90

Combine like terms:

10g + 40 = 90

10g = 50

g = 5

Plug in 5 to both equals (in this case the question only asks for 3g + 29 or KRM):

3(5) + 29 =

15 + 29 =

44 =

7(5) + 11 =

35 + 11 =

46 =

Answer:

29 m

Step-by-step explanation:

Since Jeff's coach is at the left of the platform and the platform at an angle of elevation of 37° and Jeff's parent's are on the right of the platform with the platform at an angle of elevation of 32°. The line of sight of Jeff's coach, the distance between Jeff's coach and parents and the line of sight of Jeff's parents form a triangle.

Since the platform is 10 m high, it is a perpendicular to the base of the triangle.

This perpendicular bisects the original triangle into two right angled triangles - one on the left and one on the right - with base angle 37° and 32° respectively.

Using trigonometric ratios with the opposite side to each angle the height of the platform from the ground (10 m) and the opposite angles 37° and 32° respectively, then the length of each base is gotten from

tan37° = 10/L and tan32° = 10/L' where L and L' are the lengths of each base of the two right angled triangles respectively.

So, L = 10/tan37° = 10/0.7536 = 13.3 m and L' = 10/tan32° = 10/0.6249 = 16 m.

The length d = L + L' is the distance between Jeff's coach and Jeff's parents

So, d = L + L'

= 13.3 m + 16 m

= 29.3 m

≅ 29 m to the nearest meter.

Note that we do not need the third angle in the triangle which is 100° the angle of separation between Jeff's coach and Jeff's parents which is at the base of the platform.

Answer:

Volume = 288 in.³

Step-by-step explanation:

Volume of the solid = volume of the cube + volume of the square pyramid

V = a³ + ⅓*a²*h

a = 6 in.

h = 12 - 6 = 6 in.

Plug in the values into the volume formula

Volume = 6³ + ⅓*6²*6

Volume = 216 + 72

Volume = 288 in.³

Answer:

The description is that the function was translated 4 units to the right and 8 units down.

Step-by-step explanation:

Translations:

Translating a function f(x) a units to the right is the same as finding f(x - a).

Translating a function f(x) a units to the left is the same as finding f(x + a).

Translating a function f(x) a units up is the same as finding f(x) + a.

Translating a function f(x) a units down is the same as finding f(x) - a.

y= x² to y = (x-4)²-8

First at the domain, x becomes x - 4, so f(x) becomes f(x - 4), that is, the function was translated 4 units to the right.

Then the function is subtracted by 8, that is, it was translated 8 units down.

The description is that the function was translated 4 units to the right and 8 units down.

Answer:

B) 9x² + 6x + 1

Step-by-step explanation:

use the FOIL method:

(3x + 1)(3x + 1)

F:  3x(3x) = 9x²

O:  3x(1) = 3x

I:  3x(1) = 3x

L:  1(1) = 1

combine the 'like terms' in the middle to get 6x

answer: 9x² + 6x + 1

Answer:

the answer is B. 9x^2 + 6x+1

Answer:

+4, -4

Step-by-step explanation:

There are only two solutions to this equation.

=> x^2 - 16 = 0

=> x^2 - 4^2 = 0  

=> (x+4) (x-4) = 0  {According to a^2 - b^2 = (a+b) (a-b)}

=> x = 4, -4

Answer:

x = 4

x = - 4

Step-by-step explanation:

Method 1: Quadratic Formula

Ignore the A before the ±, it wouldn't let me type it correctly.

[tex]x=\frac{-b±\sqrt{b^{2} -4ac} }{2a}[/tex]

x² - 16 = 0

a = 1

b = 0

c = - 16

[tex]x=\frac{-(0)±\sqrt{0^{2} -4((1)(-16))} }{2(1)}[/tex]

[tex]x=\frac{0±\sqrt{0 -4((1)(-16))} }{2(1)}[/tex]

[tex]x=\frac{0±\sqrt{0 +64} }{2(1)}[/tex]

[tex]x=\frac{0±\sqrt{64} }{2}[/tex]

[tex]x=\frac{0±8 }{2}[/tex]

Two separate equations

One must have a + (positive) and the other will have a - (negative).

[tex]x=\frac{0+8 }{2}[/tex]

[tex]x=\frac{8 }{2}[/tex]

x = 8 ÷ 2

x = 4

[tex]x=\frac{-8 }{2}[/tex]

x = - 8 ÷ 2

x = - 4

Method 2: Factoring

x² - 16 = 0

(x - 4)(x + 4) = 0

Two separate equations

x - 4 = 0

x + 4 = 0

x - 4 = 0

x - 4 + 4 = 0 + 4

x = 4

x + 4 = 0

x + 4 - 4 = 0 - 4

x = - 4

A: not the answer. It would be for a square or rhombus.

B: True

C: True

D: True

E: True

F: No this one is false. Consecutive sides means 1 length and 1 width. If they are congruent, you have a square or rhombus, but not a rectangle.

Hello! answer: 11

Step-by-step explanation:

60 × 60 = 3600

11 × 11 = 121

3600 + 121 = 3721

√3721 = 61

therefore 11 is the missing leg Hope that helps!

Answer:

[tex]0.98268[/tex]

Step-by-step explanation:

We are given that

Mean, [tex]\mu=3408[/tex]miles

Variance, [tex]\sigma^2=249001[/tex]

We have to find  the probability that the mean of a sample of 36 cars would differ from the population mean by less than 198 miles.

n=36

[tex]P(|\bar{x}-3408}|<198)=P(3408-198<\bar{x}<198+3408)[/tex]

=[tex]P(3210<\bar{x}<3606)[/tex]

=[tex]P(\frac{3210-3408}{\sqrt{\frac{249001}{36}}}<\frac{\bar{x}-\mu}{\sqrt{\frac{variance}{n}}}<\frac{3606-3408}{\sqrt{\frac{249001}{36}}}[/tex]

[tex]=P(-2.38<Z<2.38)[/tex]

[tex]=P(Z<2.38)-P(Z<-2.38)[/tex]

[tex]=0.99134-0.00866[/tex]

=[tex]0.98268[/tex]

Hence,  the probability that the mean of a sample of 36 cars would differ from the population mean by less than 198 miles=[tex]0.98268[/tex]

Step-by-step explanation:

P(blue shirt | girl)

This means what is the probability of a blue shirt given that we have a girl

There are 56 girls and 18 girls wearing blue shirts

P(blue shirt | girl) = girls in blue shirts / girls

                            = 18/56

                               =.321428571

Answer:

mean = 2

MAD = 3/4

Step-by-step explanation:

1, 3, 2, 2, 1, 3, 3, 1

To find the mean, add up all the numbers and then divide by the number of terms

(1+ 3+ 2+ 2+ 1+ 3+ 3+ 1)/8 = 16/8 = 2

To find the mean absolute deviation

subtract the mean and the number and then take the absolute value, add them together and then divide by the number of terms

|(1-2)| +|(3-2)| +| 2-2| +|2-2|+|1-2| +|3-2|+|3-2| +|1-2|
