70 is the mean

95+84+31 =210

210/3 = 70

Step-by-step explanation:

Perimeter of a rectangle=2(length+width)

290=2(x+2x+5)

290=6x+10

280=6x

x=46.67

width=2x+5=98.33

Answer:

m=1/2

Step-by-step explanation:

y1= 1

y2=6

x1= -10

x2-0

m= slope

m= y2-y1/x2-x1

m=6-1/0 - - 10

m= 6-1/0+10

m=5/10

m=1/2

Answer:  x=5   m is parallel to n

Step-by-step explanation:

∠2 and ∠7 are alternate exterior angles so they are equal.

So you can create the equation

40x-48 = 20x+52   Subtract 20x from both sides. Add 48 to both sides.

20x = 100

x = 5

if you need  m∠2 Substtute 5 for x in 20x+52  

20(5) + 52 = 100 +52   m∠2= 152°

m∠7  40(5) - 48 =  200-48  m∠7= 152°

Answer:

x=5   and m is parallel to n

Answer:

2 6/7

Step-by-step explanation:

You have to use the KEEP CHANGE CHANGE method. When you do this you end up with 4/7*5/1 which equals 20/7 and you then change that into a mixed number and you have your answer!

HOPE THIS HELPS!

Answer:

The answer is 2 6/7

Step-by-step explanation:

First, you set up the problem.

[tex]\frac{4}{7} / \frac{1}{5}[/tex]

Next, you change the division sign into multiplication

[tex]\frac{4}{7} x \frac{1}{5}[/tex]

Then you flip the 1/5

[tex]\frac{4}{7} x \frac{5}{1} \\[/tex]

Afterward, you multiply fractions straight across.

[tex]\frac{4}{7} x \frac{5}{1} =\frac{20}{7}[/tex]

Finally, you will simplify your answer into a mixed number.

[tex]\frac{20}{7} = 2 6/7[/tex]

Hope this helps!!

Hi there!

Your answer is:

W=17.5feet

Step-by-step explanation:

We use the surface area form for a cuboid:

2h(l+w)=SA

Fill in the known values!

2(2)* (5+ W) = 90

Solve for W!

4*(5+W)=90

20+4w=90

Answer:

75 grams

Step-by-step explanation:

If 25 cm = 10 grams

Then 1 cm = 25/10

1 cm = 2.5 grams

To find 30 cm = 2.5 times 30 grams

30 cm = 75 grams

Answer:

(4k+5)+ (6k+10) = 115

Exterior angle of a triangle is equal to the sum of two opposite interior angles

10k=15=115

10k= 100

k = 100/10

k = 10

Step-by-step explanation:

Answer:

k = 10

Step-by-step explanation:

The 3rd angle that's not defined in the equation is supplementary to 115, so the angle is 180-115 = 65.

We can solve for the equation 65+(4k+5)+(6k+10)=180 -> 65+4k+5+6k+10=180 -> 10k+80 = 180 -> 10k = 100 -> k = 10.

To double-check(optional), we can plug k back into the equation, so 65 + 4*10 + 5 + 6*10 + 10 = 180 -> 100 + 65 + 5 + 10 = 180 -> 180 = 180, so we can confirm that k = 10.

So the correct answer is D

Answer:

y=5/8x+4.5

Step-by-step explanation:

You have to do y-y divided by x-x so 7-2 which equals 5 and 4-(-4) which equals 8 so your slope is 5/8. For y-intercept, you have to do plug in one of your points into y and x in y=mx+b, so I used the point (4, 7) and I put 7 in the y spot and 4 in the x spot and I put the slope in the slope spot so now you have 7=5/8(4)+b. Next, you multiply 5/8 and 4 which gives you 5/2 or 2.5, so now you have 7=2.5+b. Then you subtract 7-2.5 which gives you 4.5 and there is your y-intercept and your whole equation is y=5/8x+4.5.

Answer: Required 99% confidence interval  : (48.30%, 61.7%)

Step-by-step explanation:

Confidence interval for PROPORTION:  [tex]p\pm z^* \times S.E.[/tex], where p = sample proportion , z* = two-tailed critical z-value  and S.E. = standard error.

As per given: p=55%

Critical z-value for 99% confidence = 2.576

S.E. = 2.6%

Then, required confidence interval :

[tex]55\% \pm (2.576)\times 2.6\%\\\\\approx55\% \pm6.70\%\\\\=(55\%-6.70\%,\ 55\%+6.70\%)\\\\=(48.30\%,\ 61.7\%)[/tex]
