The percentage error in the acceleration is 11.3%.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

The actual acceleration of the object is 9.80 meters per second.

The acceleration of an object is 10.91 meters per second.

Now,

Percentage error.

= (Experiment acceleration - Actual acceleration) / Actual acceleration x 100

= (10.91 - 9.80) / 9.80 x 100

= 1.11 / 9.80 x 100

= 11.33 %

Thus,

The percentage error is 11.3%.

Answer:

Sonny's weekly gross salary was $575

Step-by-step explanation:

Equations

Sonny works as a furniture salesman and earns a base weekly salary of $350 plus a 6% commission on sales.

This can be modeled by the function:

E(x)=350+0.06x

Where x dollars are his weekly sales.

We are given the total sales for a week are x=$3750, so his earnings are:

E(3750)=350+0.06*3750=575

Sonny's weekly gross salary was $575

Answer:

$58.64

Step-by-step explanation:

The total cost of a game g with 7% sales tax can be represented by the expression

g + 0.07g

From the above question,

g = Original price of the game = $52.

The total cost of game g =

$52 + 0.07 × $52

$52 + $3.64

= $58.64

Answer:

13.6

Step-by-step explanation:

Remember SOH CAH TOA

We're going to use tangent = opposite / adjacent because the 11 is opposite theta (39 degrees) and x is adjacent to it.

tan (39) = 11 / x

x = 11 / tan(39)

x = 13.584 -> 13.6 (rounded to nearest tenth)

Note: Make sure your calculator is in degree mode.

Answer: 2-cup bowl

Step-by-step explanation:

Given: Sam has 2-cup bowl, a 4-cup bowl, and a 6-cup bowl.

here, Quantity in 2-cup <  Quantity in 4-cup <  Quantity in 6-cup .

So,  2-cup bowl is the smallest bowl with the least capacity.

So, if Sam is interested to make the punch in the smallest bowl, then she will absolutely take  2-cup bowl.

Hence, the smallest bowl Sam can use to make the punch =2-cup bowl

Answer:

Step-by-step explanation:

In order for 4*t to equal d, the 4 has to represent a rate with respect to time because the multiplication between them will cancel the time unit. We know this because of the formula d = rt with 'r' being rate

a: 4 is the rate at which Shelby walks, 4 miles per hour

b: T is replaced with 32, so the expression tells us the distance Shelby travels in 32 hours at a rate of 4 miles per hour

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

To find a function is linear which table represent a linear function.

Now, From table 4;

Rate of change are,
