A 1600 Watts electric oven is used for 9 hours. Calculate the cost of using the $3.00 per unit of energy (Energy consumed = powe
dlinn [17]

Answer:

The cost is $43.2

Step-by-step explanation:

The first thing to do here is to calculate the amount of energy consumed.

From the question, we are told that this is;

Power * Time

From the question, power = 1600 watts

Time = 9 hours

So amount of energy consumed = 1600 watts * 9 hours = 14,400 watts hour

It should be known that energy is measured in Kilowatts hour ; So therefore 14,440 watts hour is 14,440/1000 kwh = 14.4 kwh

Now, the cost per unit of energy is $3.00 per kwh

So the cost of using 14,400 watts hour would be 14.4 * 3 = $43.2

Cynthia is in the process of constructing two tangent line segments from a point outside circle O to circle O as shown. Which li
Allisa [31]

Answer:

(B) Segments MA and MB

Step-by-step explanation:

The tangent to the circle at a point is perpendicular to the radius of the circle drawn to the point of tangency.

Tangent at a point is unique.

Since there can be no two tangents at a point on circle, the options (b) and (c) are ruled out.

Now, if OA is perpendicular to MA, MA is the tangent else if OA is perpendicular to PA, PA is the tangent. Same is the case with point B.

Tangents from the same external point has same length.

MA = MB since they are the radii of the same circle with center M.

Hence, MA and MB meet all the requirements of the tangents.

Help please with steps
SOVA2 [1]

From the image, we can see the amount of water in Liters are in the beaker.

The beaker is marked with numbers that are skip counting by 10. (10,20,30) so on. There are 4 ticks below the 10, 5 if you count the 10.

So that means 10/5 = 2 L per tick.

The water goes above the 30 mark and under the 40 mark, which means it's somewhere in the 30's.

Since each tick is 2 L, and the water goes to the third tick:

2L + 2L + 2L = 6L.

Add 6L to 30: 30+ 6L = 36L

17 + 5(x + 1)=37 <br> X= 15<br> X 3<br> X=-15<br> X=-3
aleksklad [387]

Answer:

X=3

Step-by-step explanation:

17 + 5(x + 1) = 37

17 + 5x + 5 = 37

Group like terms

5x = 37 - 17 - 5

5x = 15

\frac{5x}{5}  =  \frac{15}{5}

x = 3
