A rectangular picture frame measures 81 cm by 44 cm. What is the perimeter or distance around the picture frame in meters? m

1 answer:

7 0

The answer would be 2.5 meters. you add the two lengths together, then multiply by 2. Then divide by 100 because 100cm = 1m.

Dylan borrowed $2100 from the bank for 15 months. The bank discounted the loan at 2.6%. How much was the interest? $ State your

Answer:

actual rate of interest is 2.08 %

Step-by-step explanation:

Given data

borrowed = $2100

time = 15 months

rate = 2.6%

to find out

interest and receive from the bank and actual rate of interest

solution

we know bank discounted the loan at 2.6%

so interest will be 2.6% of $2100

that is = 2.6/100 × 2100

interest = $54.60

so receive from the bank is borrowed money - interest

receive = 2100 - 54.60

receive from the bank is $2045.40

and we can say that interest is directly proportional to time

so interest of 12 months / interest of 15 month = 12 month time/ 15 month time

here interest of 12 months = 12/15 × interest of 15 month

interest of 12 months = 12/15 × 54.60

interest of 12 months is $43.68 (annually)

now we can calculate actual rate of interest

that is = interest / borrowed money × 100

actual rate of interest = 43.68/2100 × 100

actual rate of interest is 2.08 %

Answer:

X=1

Step-by-step explanation:

Snorkel, mask, and flippers Slope: 2 (so in the equation, it would look like 2x).

Snorkel, mask, and flippers Y-intercept: 10 (12 - 2 = 10, which is 0 hours, possibly the initial amount)

Snorkel, mask, and flippers Slope intercept form: y = 2x + 10

100 points!!! i will award brainliest!! Lines AB, and CD are straight lines. Find x and y

Ket [755]

<O = 16 degrees vertical angles are equal

<O + 4x+90 = 180 DC is a straight line

16 +4x +90 = 180

106 +4x = 180

4x =74

x =18.5

16 +90 +2y= 180 DC is a straight line

106+2y=180

2y = 74

y= 37

Answer : y=37

x=18.5

erica [24]

Answer:

z=-1.591

Step-by-step explanation:

Null Hypotheses,

$H_0 : p=0.8\\H_a: p>0.80$

So we use z-test for one population proportion (right-tailed test)

According to this informaton, we defined that

$\alpha=0.05$

$z_c=1.64$ (critical value)

So our Rejection region is $R={z:z>1.64}$

$z=\frac{\bar{p}-p_0}{\sqrt{p_0(1-p_0)/n}} = \frac{0.755-0.8}{\sqrt{0.8(1-0.8)/200}}=-1.591$

Not rejection.
