Answer:

40

Step-by-step explanation:

Answer: 1.Remove any grouping symbol such as brackets and parentheses by multiplying factors.

2.Use the exponent rule to remove grouping if the terms are containing exponents.

3.Combine the like terms by addition or subtraction.

4. Combine the constants

Step-by-step explanation:

[tex]8(5w+7) + 9 ( 4w- 7)[/tex]

The first thing we do is distribute

[tex]8(5w+7)& 9(4w-7)[/tex]

We distribute what is outside the parenthesis to everything that is inside the parenthesis

so for 8(5w+7) we do [tex]8x5w = 40w[/tex] and [tex]8x7 = 56[/tex]

so for 9  So  9(4w−7) turns into 36w+63

so now we have 40w+56+36w+−63

now combine like terms

(40w+36w)+(56+−63)=?

The length of diagonal BD from the parallelogram ABCD is 10.

The midpoint of diagonals BD and AC is E. Hence, the point of bisection is marked E.

BE = DE (The diagonals of a parallelogram bisect each other)

From the diagram given :

BE = 5

DE = BE = 5

Length of BD = BE + DE

Length of BD = (5 + 5) = 10

Therefore, the length of Diagonal BD is 10.

Answer:

15 nickels and 13 dimes

Step-by-step explanation:

5n + 10d = 205 cents

n + d = 28

n = 28-d

5(28-d) +10d = 205

140 -5d + 10d = 205

5d = 65

d = 13

n = 28-d = 28-13 = 15

5n = 5(15) = 75

10d = 10(13) = 130

75+130=205

Answer:

Two identical rubber balls are dropped from different heights. Ball 1 is dropped from a height of 181 feet, and ball 2 is dropped from a height of 238 feet. Write a function for the height of each ball.

h1(t) = -16t^2 + 181

h2(t) = -16t^2 + 238

When does ball 1 reach the ground? Round to the nearest hundredth. seconds

Solve: -16t^2+181 = 0

-16t^2 = -181

t^2 = 11.3125

t = 3.3634 seconds

When does ball 2 reach the ground? Round to the nearest hundredth. seconds

This question is incomplete, the complete question is;

A fair coin is tossed three times and the events AA, BB, and CC are defined as follows: A:{A:{ At least one head is observed }} B:{B:{ At least two heads are observed }} C:{C:{ The number of heads observed is odd }} Find the following probabilities by summing the probabilities of the appropriate sample points (note that 0 is an even number): a) P(B) =, b) P(A or B) =

Answer:

a) probability of B is 0.5

b) probability of (A or B)  is 0.875

Step-by-step explanation:

Given the data in the question;

The coin is tossed 3 times.

so let S represent the sample space with the probabilities;

S = [ HHH, HHT, HTH, THH, HTT, THT, TTH, TTT ]

so n(S) = 8

now let A be the set where at least one head is observed;

A = [ HHH, HHT, HTH, THH, HTT, THT, TTH, ]

n( A) = 7

let B be the set where at least two head is observed;

B = [ HHH, HHT, HTH, THH, ]

n(B) = 4

let C be the set where number of heads are odd;

C = [ HHH, HTT, THT, TTH ]

n(C) = 4

so

a) P(B) = ?

probability of B will be;

P(B) = n(B) / n(S)

we substitute

P(B) = 4 / 8 = 0.5

Therefore, probability of B is 0.5

b) P(A or B) = ?

the favorable number of cases to event A∪B is

A∪B = [ HHH, HHT, HTH, THH, HTT, THT, TTH, ]∪[ HHH, HHT, HTH, THH, ]  

A∪B = [ HHH, HHT, HTH, THH, HTT, THT, TTH, ]

n(A∪B) = 7

Now the probability of A or B will be

P( A∪B ) = n(A∪B) / n(S) = 7/8 = 0.875

Therefore, probability of (A or B)  is 0.875
