Answer:

(1) length AB = 21.0

(2) length BC = 45.0

Step-by-step explanation:

(1) To determine AB, apply Cosine rule;

[tex]|AB|^2 = |AC|^2 + |BC|^2 \ - \ 2[|AC| \times |BC]cos \ C\\\\|AB|^2 = 13^2 + 29^2 \ - \ 2(13 \times 29) cos(41)\\\\|AB|^2 = 1010 - 569.05\\\\|AB|^2 = 440.95\\\\|AB|= \sqrt{ 440.95} \\\\|AB| = 21.0[/tex]

(2) To determine BC, also apply cosine rule;

[tex]|BC|^2 = |AB|^2 + |AC|^2 \ - \ 2[|AB| \times |AC]cos \ A\\\\|BC|^2 = 30^2 + 21^2 \ - \ 2(30 \times 21) cos(123)\\\\|BC|^2 = 1341 - (-686.245)\\\\|BC|^2 = 1341 + 686.245\\\\ |BC| = 2027.245\\\\|BC|= \sqrt{ 2027.245} \\\\|BC| = 45.0[/tex]

Answer:

32

Step-by-step explanation:

Answer:

b.This is a subtraction expression

d.To evaluate, substitute 29 for the variable in the expression.

g.The correct expression is n minus 31.

h.To evaluate the expression, subtract 31 from 29.

Step-by-step explanation:

Given:

"a number, n, decreased by thirty-one."

n - 31

If n = 29

n - 31

29 - 31

= -2

a.The correct expression is 31-n.

b.This is a subtraction expression.

c.This is an addition expression.

d.To evaluate, substitute 29 for the variable in the expression.

e.To evaluate, substitute 31 for the variable in the equation.

f.To evaluate the expression, add 31 to 29.

g.The correct expression is n minus 31.

h.To evaluate the expression, subtract 31 from 29.

The following statement are TRUE:

b.This is a subtraction expression

d.To evaluate, substitute 29 for the variable in the expression.

g.The correct expression is n minus 31.

h.To evaluate the expression, subtract 31 from 29.

Answer:

11

Step-by-step explanation:

square of 44 + 77

1st step = go with the number that is inside the square

that will 44+77 = 121

now using the square root , you may think about which number multiple by himself give you 121

11×11 =121

so square root of 121 = 11

[tex] \sf Q) \sqrt{44 + 77} = {?} [/tex]

[tex] \sf \implies \sqrt{44 + 77} [/tex]

[tex] \sf \implies \sqrt{121} [/tex]

[tex] \sf \implies 11[/tex] is the required answer.

Answer:

730 x 0.028 = (assuming per year) 20.44

20.44 x 5 = 102.2

102.2 + 730 = 832.2

Your final answer is 832.2

Step-by-step explanation:

Hope this helps!

The value of amount will be in Jean's account after 5 years is,

⇒ Amount = $832.2

The multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

We have to given that;

Jean deposits $730 in an account that pays 2.8% simple interest.

And,  He neither adds more money nor withdraws any mone from his account.

Now, We know that;

Interest = PRT / 100

Where, P is principal amount,

R is rate

And, t is time.

Hence, Substitute the values we get;

Interest = 730 x 2.8 x 5 /100

            = $102.2

Hence, The value of amount will be in Jean's account after 5 years is,

⇒ $730 + $102.2

⇒ $832.2

Therefore, The value of amount will be in Jean's account after 5 years is,

⇒ Amount = $832.2
