What is the value of the expression “-5(3+5)”

Answer:

  I

Step-by-step explanation:

Reflecting the point across both axes changes the signs of both coordinates. The reflected point will be (2, 8). Both coordinates are positive for points in Quadrant I.

Answer:

A) x = 0, y = 14

Step-by-step explanation:

Line A:  y = 6x + 14

Therefore, the slope of line A = 6

If Line B is perpendicular to Line A, then the product of their slopes is -1.

⇒ slope of Line B = [tex]-\dfrac16[/tex]

Given Line B passes through point (2, 13 2/3).

Use slope-point form of linear equation to find equation for Line B:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-13 \frac23=-\dfrac16(x-2)[/tex]

[tex]\implies y=-\dfrac16x+14[/tex]

Solution of system is the point where the lines intersect.

From inspection of the equations of the lines, the point of intersection is (0, 14)

We have given that,

The fixed price of a taxi journey costs $11.50 plus $5 per traveled kilometer.

We have to determine How much will you pay for a journey of 20 kilometers.

We have $11.5 fixed.

We have to determine for 20km we have to pay.

20k * $5 = $100

$100 + 11.5 = 111.5

Answer:

The team is measuring 333 feet below the surface.

Step-by-step explanation:

Step 1. Write the function out

P = 14 +(8d/9)

Step 2. Plug in the (P )ounds [310]

310 = 14 + (8d/9)

Step 3. Remove 14 from the right side of the equation (Subtract 14 from everything)

296 = 8d/9

Step 4. Remove 9 from the right side of the equation (Multiply everything by 9)

2664 = 8d

Step 5. Remove 8 from the right side of the equation (Divide everything by 8)

333 = d

Final Answer: The team is measuring 333 feet below the surface.

The amount of money Jamar will make in his 18th year working at this job is = $107,500

The amount of money Jamar made in his first year= $48,000

The salary rise per year = $3,500

The amount of money he will make for the extra 17 years is = 17 × $3,500

= $59,500

Therefore the amount he will receive as his salary in the 18th year working at this job = $48,000 + $59,500

Your Answer Should Be.... B

Answer:

B

Step-by-step explanation:

-8.56 = 64.2 divided  7.5

Answer:

Step-by-step explanation:

The simple interest formula is ...

  I = Prt . . . . . r is the interest rate, t is the number of years

Solving for P, we have ...

  P = I/(rt)

6 months is 1/2 year, so the principal is ...

  P = $4.38/(0.035×1/2) = $250.2857...

Rounded to the nearest dollar, the principal invested is $250.

__

Using the same approach, for 18 months, t = 18/12 = 3/2 = 1.5.

  P = $20.70/(0.023×1.5) = $600

The principal in Account B is $600.

__

First Month's Interest

Using the interest formula, the first month's interest in each account is ...

  A: I = 250×0.035×1/12 = $0.73

  B: I = 600×0.023×1/12 = $1.15

Account B earns more interest in the first month.

11/10 is greater than 1

Step-by-step explanation:

For reference, 10/10 = 1, 8/8 = 1. So when looking at these:

11/10 is 1 and 1/10

7/8 is less than 1

well, the original price was "x", which is of course the 100%, the new price is 10% less than that, or namely 90% of that original and we know is 200 bucks.

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 200&90 \end{array}\implies \cfrac{x}{200}=\cfrac{100}{90}\implies \cfrac{x}{200}=\cfrac{10}{9} \\\\\\ 9x=2000\implies x=\cfrac{2000}{9}\implies x=222.\overline{2}[/tex]

Answer:

y = 14 [tex](2)^{x}[/tex]

Step-by-step explanation:

Find a and b by substituting the points into the equation

using (0, 14 ) , then

14 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ] , then

14 = a × 1 ⇒ a = 14

y = 14 [tex]b^{x}[/tex]

using (6, 896 )

896 = 14 [tex]b^{6}[/tex] ( divide both sides by 14 )

64 = [tex]b^{6}[/tex] ( take the sixth root of both sides )

b = [tex]\sqrt[6]{64}[/tex] = 2

Then

y = 14 [tex](2)^{x}[/tex] ← is the exponential function

Given b=4 and ∠β=20°,

a = 10.98991

The height of the bamboo plant after 15 days is 316 inches.

In order to determine the formula that represents the rate of growth of the bamboo plant, we have to determine the inches of growth per day.

Rate of growth per day = 134 - 121 = 13 inches

The height of the bamboo plant = 121 + 13h

Where h is the number of days

Height in 15 days = = 121 + (13 x 15)

Answer :

92 bc you’d get 92.16 but round down

Answer:

y= 95.

180°-120°=60° (adding 120° with x should give you 180°)

x=60°

25°+60°=85°

180°-85°=95

Answer:

y=95

Step-by-step explanation:

we know that the triangle angles sum is 180°

to find Y you should find x

we are going to find x, we know that a straight angle is 180, to find the x you should:

[tex]120+x=180[/tex]

move 120 to the other side with a negative sign:

[tex]x=180-120\\x=60[/tex]

angle [tex]x=60[/tex]

now we know enough angles to find y:

[tex]25+60+y=180[/tex]

25 is given in the picure and 60 is the x angle while 180 is the sum of a triangle angles, we have to flip the equaton to find y:

[tex]25+60+y=180\\85+y=180\\y=180-85\\y=95[/tex]

Answer:

1 minute

Step-by-step explanation:

1km = 1000m

30km = 30000m

30km ÷ 60 = 500m

it takes one hour to go 30km or a ratio of 30km to 1hour. 1hour is also 60minutes. 30:60

divide both sides by 60 gets 500m and the amount of time to go that distance 1 minute

Answer:

1/60 hr or 1 minute

Step-by-step explanation:

30 km per hour

30 km : 1 hr

convert 500 metres to km

1 km = 1000 metres

500 ÷ 1000 = 0.5 km

using ratios

30 km : 1 hr

0.5 km : x hr

to get from 30 to 0.5 multiply by 1/60 ( we got this from doing 0.5 ÷ 30) , so do the same to the other side

1 hr × 1/60 = 1/60 hr

you can convert to minutes = 1/60 × 60 = 1 minute
