Find the perimeter of the parallelogram.

Will mark brainlyest!!

Answer:

-7

Step-by-step explanation:

-2 + 3v = -23 >> -2 + 23 = -3v >> 21 = -3v >> v = -7

Answer:

V=-7

Step-by-step explanation:

To solve this equation, you must first add the -2 to both sides. (This cancels it out since you only want one variable on each side of the equation. It would be the other way around if the variable were positive) Now that you have the equation 3v=-21, you can divide. To get the v by itself, you must divide both sides by 3. This gives you the answer to the equation.

Hope this helps!!

Answer:

170 cm

Step-by-step explanation:

2 * 1 1/2 * 2 = 6

1 1/2 * 4 * 2 = 12

2 * 4 * 2 = 16

In total: 6 + 12 + 16 = 34.  

Samir needs to cover 5 of these blocks so: 34 x 5 = 170

I also did the quiz.

Answer:

627 miles north

747 miles east

Step-by-step explanation:

Bearing angles are measured east of north, so in (N, E) coordinates, the final position of the plane is ...

 (1.5 h)(650 mi/h)(cos(50°), sin(50°)) = (975cos(50°), 975sin(50°)) mi

 = (626.72, 746.89) mi

The plane will be 627 miles north and 747 miles east of its point of departure.

im pretty sure this is it but sorry if it aint

We have two samples, A and B, so we need to construct a 2 Samp T Int using this formula:

In order to use t*, we need to check conditions for using a t-distribution first.

Since 2/3 conditions aren't met, we can still proceed with the problem but keep in mind that the results will not be as accurate until more data is collected or more information is given in the problem.

Solve for t*:

We need the tail area first.

Next we need the degree of freedom.

The degree of freedom can be found by subtracting the degree of freedom for A and B.

The general formula is df = n - 1.

Use a calculator or a t-table to find the corresponding t-score for df = 5 and tail area = .05.

Now we can use the formula at the very top to construct a confidence interval for two sample means.

Substitute the variables into the formula: [tex]\displaystyle \overline {x}_1 - \overline {x}_2 \ \pm \ t^{*} \sqrt{\frac{s_1^2}{n_1} + \frac{s_2^2}{n_2} }[/tex].

Simplify this expression.

Adding and subtracting 3.73139 to and from -16 gives us a confidence interval of:

If we want to interpret the confidence interval of (-20.5707, -11.4293), we can say...

We are 90% confident that the interval from -20.5707 to -11.4293 holds the true mean of items sold at locations A and B.

Answer:

oranges lasts for 9 days

Step-by-step explanation:

To find out the number of days, we have to divide the total oranges by the quatity of oranges used each day.

Number of days = Total oranges ÷ number of oranges used per day

Answer:

x = 2

y = -3

Step-by-step explanation:

y = x - 5  -------------------(I)

x + y = -1 ----------------(II)

Substitute y = x -5 in equation (II)

x + (x - 5) = -1

x + x - 5 = -1   {Combine like terms}

   2x - 5 = -1 {Add 5 to both sides}

        2x  = -1 + 5

         2x = 4 {Divide both sides by 2}

           x = 4/2

x = 2

Substitute x = 2 in equation (I)

y = 2 - 5

y = -3

Answer:

60°

Step-by-step explanation:

the triangle need to have 180°. The up right corner is 60 because 120 + 60 = 180. Then I extended to rhombus where you have two sets of same angles. 125 + 55 = 180. 125 + 125 = 250. 360 - 250 = 110. 110 ÷ 2 = 60

Answer:

We need to find Factors of 14 that will also add and equal to 5

Step-by-step explanation:

Trinomial factorising

Answer:

see explanation

Step-by-step explanation:

p² - 5p - 14

We need to find the factors of the constant term (- 14) that will also add to give the coefficient of the p- term (- 5)

the factors are - 7 and + 2 , since

- 7 × + 2 = - 14 and - 7 + 2 = - 5

then

p² - 5p - 14 = (p - 7)(p + 2) ← in factored form

Answer:0,10

Step-by-step explanation: When translating you either add or subtract. If the problem says go down or to the left, you know that you will be subtracting, and if it says go up or to the right you will be adding. So up would add 4 to the x value which gives you 0 and you add 2 to the y value you get 10.

Answer:

(0, 10)

Step-by-step explanation:

-4 + 4 = 0

8 + 2

To verify, you can find the coordinates (0, 10) on a graph.

Answer:

42 minutes

Step-by-step explanation:

there are 60 minutes in one hour.

from 12 pm, 1 hour and 35 minutes have passed to get to 1:35 pm

from 12 pm, 2 hours and 17 minutes have passed to get to 2:17 pm

we are trying to figure out the start to end time, or the difference between the times

2 hours and 17 minutes - 1 hour and 35 minutes

1 hour = 60 minutes

if we convert everything to minutes we can get a definitive time in one single unit

2 hours = 1 hour * 2 = 60 minutes * 2 = 120 minutes

1 hour = 60 minutes

plug these in

(120 + 17) minutes - (60 + 35) minutes

= 137 minutes - 95 minutes

= 42 minutes as our answer
