Step-by-step explanation:

Given the interval for the measurement to be  60 m ± 4.5%, the posible range of each measurement is expressed as shown;

60 m ± 4.5% =  60 m ± 4.5/100

=  60 m ± 0.045

= (60 - 0.045, 60+0.045)

= (59.955, 60.045)

Hence possible range of each measurement to the nearest tenth is (60.0m≤60.1m)

Answer:

Step-by-step explanation:

Well you can calculate the area of the base side by the integration of cos - sin x over the limits x = 0 and x = π/6.

Then I think one side of the square  would be cos π/6 - sin  π/6.

So I think the required volume  can be worked out as area of base * length of a side of the square.

I think that,s the way to do it, if i have interpreted the question correctly.

Answer:

Step-by-step explanation:

The domain of a graph is the span of x-values (or t-values in this case) it covers.

From the graph, we can see that the graph stretches from t=0 to t=14.

Also, note that since the endpoints are closed circles, we will include them within our domain.

Therefore, our domain is all values greater than or equal to 0 and less than or equal to 14.

In set notation, this is:

[tex]\{t|0\leq t\leq 14\}[/tex]

So, our answer is A

Answer:

One taco costs $3.75.

Step-by-step explanation:

Let x = cost of taco

You order 2 tacos: 2x

You add a salad: 2x + 2.5

You pay 8% sales tax on 2x + 2.5, so you pay 1.08(2x + 2.5)

You leave a $3 tip, so the total you pay is: 1.08(2x + 2.5) + 3

The total you pay is $13.80

1.08(2x + 2.5) + 3 = 13.80

Subtract 3 from both sides.

1.08(2x + 2.5) = 10.8

Divide both sides by 1.08

2x + 2.5 = 10

Subtract 2.5 from both sides.

2x = 7.5

x = 3.75

One taco costs $3.75.

Answer:

y/( 3b-7)=x

Step-by-step explanation:

y=3bx-7x

Factor out x

y=(3b-7)x

Divide each side by (3b-7)

y/( 3b-7)=(3b-7)x/ ( 3b-7)

y/( 3b-7)=x

Answer:

[tex]\huge \boxed{x= \frac{y}{3b-7} }[/tex]

Step-by-step explanation:

[tex]\sf y=3bx-7x[/tex]

Factor out x from the expression.

[tex]\sf y=x(3b-7)[/tex]

Divide both sides by (3b - 7).

[tex]\sf \displaystyle \frac{y}{3b-7} =x[/tex]

Answer:

The probability is 0.044

Step-by-step explanation:

Let p be the probability that the new principal’s performance is approved.

This is obtainable from the survey and it is 8/10 = 0.8

Let q be the probability that the new principal’s performance is disproved.

That will be;

1 - q = 1- 0.8 = 0.2

To calculate the probability that 14 parents names are chosen at random and they all

approve of the principal’s performance, we use the Bernoulli approximation of the binomial theorem.

That will be;

14C14 * p^14 * q^0

= 1 * 0.8^14 * 0.2^0

= 0.043980465111 which is approximately 0.044

Answer:

600,000

Step-by-step explanation:

When rounding to the nearest 100,000 if it's X50,000 you round up 1 for the X, if it's X49,999 or less you keep the X as is.

229,275 rounding to the hundred thousand would be 200,000

115,368 would be 100,000

344,633 would be 300,000

so 200,000+100,000+300,000 = 600,000

Answer:

a.) 11>2x.

b.) 2<5÷x.

c.) 4(x+8).

The word phrases into an algebraic expression will be 2x + 11, 5/x - 2, and 4(x + 8).

The act of converting a specified statement into an expression or equation is known as a sentence-to-equation transformation.

Convert all the word phrases into an algebraic expression. Then we have

a. 11 more than twice a number x. Then we have

⇒ 2x + 11

b. 2 less than the quotient of 5 and a number x. Then we have

⇒ 5/x - 2

c. The product of 4 and the sum of a number x and 8. Then we have

⇒ 4(x + 8)

The word phrases into an algebraic expression will be 2x + 11, 5/x - 2, and 4(x + 8).

My answer is a Cartesian Coordinate System.

Answer:

Step-by-step explanation:

Given the amount of water in millilitres to be 10 ml

Time taken for the water to flow = 8.5 seconds

Rate of flow in ml/sec = amount of water (in ml)/Time taken(in secs)

Rate of flow in ml/sec = 10ml/8.5scs

To express the resulting value in litres per minute, we will use the following conversion:

1 millilitre = 10⁻³litres

60secs = 1 minute

Converting 10ml to litres:

If 1 millilitre = 10⁻³litres

10 millilitres = (10*10⁻³)litres

Converting 8.5secs to minute:

If 60secs = 1 minute

8.5secs = (8.5/60)minutes

8.5secs = 0.1417 minutes

10ml/8.5scs in litre/sec:

10ml/8.5scs = (10*10⁻³)litres/0.1417 minutes

10ml/8.5scs  = (0.01/0.147)litres/min

10ml/8.5scs  = 0.07litres/minute (to the nearest hundredth)

Hence the rate of flow in liters per minute to the nearest hundredth is 0.07litres per minute.

Answer:

Step-by-step explanation:

Rotational symmetry is when a shape has the same orientation after being rotated.

For example, an equilateral triangle rotated 120° will line back up with itself.  A square rotated 90° will also return to its original orientation.  Same with a pentagon rotated 72°.

Basically, an n-gon rotated by a multiple of 360°/n will return to its original position.

θ = k 360°/n

For the first rotation:

160° = k 360°/n

160 / 360 = k / n

4/9 = k/n

For the second rotation:

120° = k 360°/n

120 / 360 = k / n

1/3 = k/n

For the third rotation:

80° = k 360°/n

80 / 360 = k / n

2/9 = k/n

For the fourth rotation:

280° = k 360°/n

280 / 360 = k / n

7/9 = k/n

The total rotation angle is -160°.

160 = k 360/n

160 / 360 = k / n

4/9 = k/n

Comparing the denominators, n must be the smallest multiple of 3 and 9.  Therefore, n = 9.

Answer:

Step-by-step explanation:

By calculating the slope, we can say that the table best describes the change in Y with respect to X.

Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line.

Equation of line is y = mx + c where m is the slope.

Similarly, in y = 0.25x, 0.25 is the slope.

For the table, we need to calculate slope.

[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

[tex]m = \frac{0.8-0.4}{2-1}[/tex]

m = 0.4

As we compare, it is clear that the slope calculated from the table is greater.
