|9-(-1)|= simplify the expression

Step-by-step explanation:

1. 1/6d - 8 = 5/8

1/6d -8 + 8 = 5/8 + 8

1/6d = 69/8

1/6d / 1/6 = 69/8 / 1/6

d = 51.75 or [tex]51\frac{3}{4}[/tex]

2. 3x - 4 + 5x = 10 - 2z

8x - 4 = 10 - 2z

8x - 4 + 4 = 10 - 2z + 4

8x = 14 - 2z

8x / 8 = (14 - 2z) / 8

x = [tex]\frac{14 - 2z}{8}[/tex]

3. 7(c  - 3) = 14

7(c - 3) / 7 = 14 / 7

c - 3 = 2

c - 3 + 3 = 2 + 3

c = 5

4. 11(m / 22 + 3 / 44) = 87

m / 22 + 3 / 44 = 87 / 11

m / 22 + 3 / 44 = 348 / 44

m / 22 = 345 / 44

m = 172.5

5. ck + 5k = a

k(c + 5) = a

k = [tex]\frac{a}{c+5}[/tex]

Answer:

C, None of the above

Step-by-step explanation:

Step 1: Expand the brackets

-7 - 3(-4e-3)

-7 + 12e + 9

Step 2: Collect like terms

12e + 2

Because the answer is not a or b the answer is 'None of the Above'

Hey there! I'm happy to help!

Let's use the distributive property to undo the parentheses. We multiply the number next to the parentheses by each number inside of the parentheses.

-7+3(-4e-3)

-7-12e-9

We combine like terms.

-16-12e

This means that Answer B is incorrect. Answer A could still be correct though as it could have equal value to -16-12e.

-4(3e+4)

We use distributive property.

-12e-16

We see that these have the same value, so the correct answer is A.

Have a wonderful day! :D

Step-by-step explanation:

Given:

Annual pay = $45,000

Find:

Per month salary

Computation:

Number of month in a year = 12

Per month salary = Annual pay / Number of month in a year

Per month salary = $45,000 / 12

Answer:

The graph of p(x) stretch vertically by factor 2 and shifts 3 units left and 6 units down to get q(x).

Step-by-step explanation:

It is given that p(x) and q(x) are two functions such that

[tex]q(x)=2p(x+3)-6[/tex]    ...(1)

The translation is defined as

[tex]q(x)=kp(x+a)+b[/tex]              .... (2)

Where, k is stretch factor, a is horizontal shift and b is vertical shift.

If 0<k<1, then the graph compressed vertically by factor k and if k>1, then the graph stretch vertically by factor k.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

On comparing (1) and (2) we get

k=2>1, so the graph of p(x) stretch vertically by factor 2.

a=3>0, so the graph of p(x) shifts 3 units left.

b=-6<0, so the graph of p(x) shifts 6 units down.

Therefore, the graph of p(x) stretch vertically by factor 2 and shifts 3 units left and 6 units down to get q(x).

Answer:

x= 11.33 years

Step-by-step explanation:

Y1= −19.76x + 227

Y2= = –92.57x + 1052

Y1 = Y2

–19.76x + 227 = –92.57x + 1052

Collect like terms and Simplify

-19.76x + 92.57x = 1052 - 227

72.81x = 825

Divide both sides by 72.81

x= 825 / 72.81

=11.33 years

Therefore,

x= 11.33 years

The solution for x is 11.33 years.

Given,

The linear function that models the population of rainbow smelt is[tex]y_{1} = -19.76x + 227[/tex]

The linear function that models the population of bloater fish is [tex]y_{2} =-92.57x + 1052[/tex]

Since, According to the question,

[tex]y_{2}=y_{1}[/tex]

[tex]-19.76x + 227 =-92.57x+1052[/tex]

On solving for x

[tex]-19.76x + 92.57x = 1052 - 227[/tex]

[tex]72.81x = 825[/tex]

Divide both sides by 72.81

[tex]x= \dfrac{825}{72.81}[/tex]

[tex]x=11.33 \ years[/tex]

Hence the solution for x is 11.33 years.

Step-by-step explanation:

l = 12 , b = 7 , d = 4 , r = 3 and h = 10

V = 336 + 90π

surface area = [2(lb + ld + bd) - πr²] - [2πrh + πr²]

Answer:

2.6 hours

2 hours 36 minutes.

Step-by-step explanation:

Let the time be x hours

we know

distance = speed*time

speed of one train = 85 miles/hour

time = x hours

distance traveled by one train = 85*x = 85x miles

speed of one train = 95 miles/hour

time = x hours

distance traveled by other  train = 95*x = 95x miles

__________________________________________________

Given that

Two trains leave stations 468 miles apart at the same time and travel toward each other

Thus, together cover 468 miles.

distance traveled by one train + distance traveled by other train = 468

85x+95x = 468

=> 180x = 468

=> x = 468/180 = 2.6

Thus, it will take 2.6 hours to meet each other

we know 1 hour = 60 minutes

0.6 hour = 60*0.6 minutes = 36 minutes

Thus, we can also say that it took 2 hours 36 minutes to meet each other.

Answer: check all the answers except cos(x+y)+cos(x-y)=cos^2 x-sin^2 y

Step-by-step explanation:

took the test and hopefully mine was the same as the image above

Answer:

a. m∠Z =  62

b. [tex]m\widehat{WZ}[/tex] = 118

c.  m∠W = 62

d. [tex]m\widehat{WX}[/tex] = 122°

Step-by-step explanation:

a. The given parameters are;

m∠X = 118

[tex]\overline {WZ} \cong \overline {YZ}[/tex]

m∠Y = 120

m∠X + m∠Z = 180  Angles in opposite segment are supplementary

m∠Z = 180 - m∠X  = 180 - 118 = 62

m∠Z =  62

b. Given [tex]\overline {WZ} \cong \overline {YZ}[/tex] line drawn from W to Y forms isosceles triangles WZY, with base angles ∠WYZ and ∠YWZ equal (Base angles of an isosceles triangle)

Therefore

∠WYZ + ∠YWZ + m∠Z = 180 (Angle sum theorem)

∠WYZ = ∠YWZ (Substitution property of equality)

∠WYZ + ∠YWZ + m∠Z = ∠WYZ + ∠WYZ + m∠Z =180

2×∠WYZ + 62 =180

2×∠WYZ = 180 -62 = 118°

∠WYZ =  118°/2 =59

∠WYZ = ∠YWZ = 59

[tex]m\widehat{WZ}[/tex] subtends chord WZ at the center  =  ∠WYZ  subtends chord WZ at the circumference

∴ 2×∠WYZ = [tex]m\widehat{WZ}[/tex]

[tex]m\widehat{WZ}[/tex]  = 2×59 = 118

[tex]m\widehat{WZ}[/tex] = 118

c.  m∠X + m∠Y + m∠Z + m∠W = 360 (Sum of angles in a quadrilateral)

m∠W = 360 - (m∠X + m∠Y + m∠Z) = 360 - (118 + 120 + 60) = 62

m∠W = 62

d. [tex]m\widehat{WZ}[/tex] + [tex]m\widehat{WX}[/tex] = [tex]m\widehat{XWZ}[/tex]  (Angle addition postulate)

[tex]m\widehat{XWZ}[/tex] = 2 × ∠Y (Angle subtended at the center = 2 × Angle subtended at the circumference

∴ [tex]m\widehat{XWZ}[/tex] = 2 × 120 = 240

[tex]m\widehat{WX}[/tex] = [tex]m\widehat{XWZ}[/tex] - [tex]m\widehat{WZ}[/tex]

[tex]m\widehat{WX}[/tex] = 240 - 118 = 122°

[tex]m\widehat{WX}[/tex] = 122°.

Add 7x to both sides

● -7x +7x + 5y = 35+7x

Answer:

4 t shirts.

Step-by-step explanation:

Given that money available with Sam = $150

Price for pants = $90

Price of each t shirt = $12.50

To find:

How many t shirts can he expect to purchase?

Solution:

Price for 2 pants = $180 which is more than $150.

Therefore, he can not buy more than 1 pants.

The remaining amount after buying pants = $150 - $90 = $60

This amount will be used for buying t-shirts.

Number of t-shirts that can be bought:

[tex]\dfrac{60}{12.5} \approx 4.8[/tex]

But answer in decimal points for number of t shirts is not possible and he does not have more money.

It means, he can buy at most 4 t-shirts.

Answer:

Step-by-step explanation:

To find y we use tan

tan∅ = opposite/ adjacent

From the question

8 is the adjacent

10 is the opposite

Substitute the values into the above formula

That's

[tex] \tan(y) = \frac{10}{8} [/tex]

Answer:

b. His t-score is 40.

Step-by-step explanation:

The middle of the third stanine in a normal distribution means that the standard of nine that is applied has the middle of the third count.

It means that if we divide the normal distribution with the standard of nine we will find the score to be  the middle of the  third division.

So it will be (1/3*9=3) more than 3.

Which in normal distribution will be more than 30.

The t distribution is approximately normal when the number of degrees of freedom is greater than 30 .

So the best answer is that His t-score is 40  ( choice b).
