Answer:

B

Step-by-step explanation:

here, we can use the pythagorean theorem. more info here: https://en.wikipedia.org/wiki/Pythagorean_theorem

formula: a^2+b^2=c^2

so we can apply the formula by doing this:

9^2+12^2=c^2

81+144=c^2

81+144=225

c=√225

c=15

Answer:

  406.3 cm²

Step-by-step explanation:

The total surface area is the sum of the base area and the lateral area. The lateral area is the sum of the areas of the 6 congruent triangular faces.

__

Each triangular face has a base of 8 cm and a slant height of 10 cm. Its area is ...

  A = 1/2bh

  A = 1/2(8 cm)(10 cm) = 40 cm²

Then the area of 6 faces is 6×40 cm² = 240 cm².

The base area is given.

The total area is the sum of the lateral area and the base area:

  total area = 240 cm² +166.3 cm² = 406.3 cm²

The surface area is about 406.3 cm².

What graph represents the piecewise-defined function? 6 if x 3 y = 3 if 3 < x < 2 5 if x 2 >

Answer:

a pendulum consists of a mass hanging at the end of a string which is 18 cm long. find the vertical height through which the mass rises and falls as the pendulum swings through 30°on each side of the vertical.

Answer:

1. P = IRT

T = P/IR

2. A = 2(L + W)

L + W = A/2

W = A/2 - L

3. y = 5x - 6

x = (y +6)/5

4. 2x - 3y = 8

y = (2x - 8)/3

5. (x+y)/3 = 5

x = 5×3 - y

x = 15 - y

6. y = mx + b

b = y - mx

7. ax + by = c

by = c - ax

y = (c - ax)/b

The number of T-shirts and shorts did Dots sell in the month of April with the total sales of $570 are 60 and 30 respectively.

A system of equation is the set of equation in which the finite set of equation is present for which the common solution is sought.

Dots sells T-shirts ($5) and shorts ($9).

Let suppose the number of T-shirts sold is x and shorts sold is y. Dots sells T-shirts ($5) and shorts ($9) with total sales of $570. Thus,

[tex]5x+9y=570[/tex]

Solve it further,

[tex]5x+9y=570\\9y=570-5x\\y=\dfrac{570-5x}{9}[/tex]                  ....1

People bought 2 times as many T-shirts as shorts. Thus,

[tex]x=2y[/tex]                          ....1

Put the value of y form equation in this equation as,

[tex]x=2\times\dfrac{570-5x}{9}\\9x=1140-10x\\10x+9x=1140\\x=\dfrac{1140}{19}\\x=60[/tex]

Put this value of x in equation 2 as,

[tex]x=2\times y\\60=2\times y\\y=\dfrac{60}{2}\\y=30[/tex]

Thus, the number of T-shirts and shorts did Dots sell in the month of April with the total sales of $570 are 60 and 30 respectively.

Conversion of decimal number 10 into binary is:

10 / 2 = 5 with remainder 0

5 / 2 = 2 with remainder 1

2 / 2 = 1 with remainder 0

1 / 2 = 0 with remainder 1

Therefore, the 10 in decimal is equal to 1010 in binary.

Analog multimeters are multifunction electrical measuring instruments with indicationby means of an arrow (analog) scale.

Modern analog multimeter

Advantages of analog multimeters:

Possibility to carry out measurements at low temperatures down to -30 ° С.Fast operation with a large amount of measurements, when high precision is not required.Do not require power consumption from the built-in power supply in the mode of voltage and current measurement.Instant display of the dynamics of the signal change.

Disadvantages and features:

Non-linear scale and setting zero before starting measurements.Absence of automatic detection of voltage polarity.A small set of functions: most models can measure only DC and AC voltage, DC current and resistance.Low input resistance and, consequently, a high error in low-voltage measurements.Sensitivity to mechanical damage, vibration.

Digital multimeters are modern, reliable measuring devices characterized by high measurement accuracy and various functional capabilities. Digital devices have replaced analogue in connection with the possibility of wide application of semiconductor technologies. Today most of the produced multimeters are digital. Specialists working with electrical equipment, if necessary, can choose among the digital multimeters a model focused on a specific task.

Advantages of digital multimeters:

Maximum possible measurement accuracy.Automatic polarity detection: If the probes are connected incorrectly, the correct values with a minus sign appear on the screen.Possibility of automatic and manual selection of measuring ranges.Multifunctionality.Does not require mandatory zero adjustment.The accuracy of the meter reading does not depend on the battery charge.Resistance to mechanical damage.The ability to record measurement results in memory and synchronize with a PC.

Step-by-step explanation:

Because 7+3=10 and 10x5=50. And also 35+15=50 so 50 and 50

Hey there!

35 + 15

= 50

Option A.

7(5 + 2)

= 7(5) + 7(2)

= 35 + 14

= 49

49 ≠ 50

Option B.
5(6 + 3)

= 5(6) + 5(3)

= 30 + 15

= 45

45 ≠ 50

Option C.

5(7 + 3)

= 5(7) + 5(3)

= 35 + 15

Answer:

[tex]\mathrm {(x - 8)(x + 8)}[/tex]

had to be corrected. sorry for the inconvenience.

Answer:

(x - 8)(x + 8) will be your answer.

Step-by-step explanation:

Lets do this step by step.

1) Find the GCF of the expression.

2x^2 - 32x - 128 --> 2(x^2 - 16x - 64)

2) Use the X-method to factor.

It gives us the expression 2(x^2 - 8x)(-8x -64).

3) Factor for x.

(x^2 - 8x) --> x(x - 8)

(-8x - 64) --> -8(x + 8)

Our answer is (x - 8)(x + 8)

Answer:

693.19 m^2.

Step-by-step explanation:

This consists of 2 triangles and 3 rectangles,

Surface area = 2 * 1/2 * 3 * 9 + 9*31 + 3*31 + 9.49*31

=  27 + 279 + 93 + 294.19

= 693.19 m^2

The value of n is 32 if the total; base length is 12(8+4) and n is the length of the perpendicular.

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

We can use the altitude rule:

8/n = n/4

n² = 32

n = √32

Thus, the value of n is 32 if the total; base length is 12(8+4) and n is the length of the perpendicular.
