Evaluate expression: -5a -b for a= -6 and b= 3

Answer:

it is a right triangle

Step-by-step explanation:

Answer:

No, it's not a right triangle

Step-by-step explanation:

Use a^2 + b^2 = c^3 to find if it's a right triangle

a^2 + b^2 = c^3

(13)^2 + ([tex]\sqrt{29}[/tex] )^2 = (14)^2

169 + 29 = 196

198 [tex]\neq[/tex] 196

The perimeter of the floor in the scale drawing is 36 inches.

What is the area of the rectangle?

To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.

The scale of the drawing is 10 inches for 40 feet, which means that every inch in the drawing represents 4 feet in reality.

To find the perimeter of the floor in the scale drawing, we can add up the length of each side in the drawing, where every inch represents 4 feet.

The length of the floor is 40 feet, which is equal to 10 inches in the scale drawing (40/4=10). So, the length of the scale drawing is 10 inches.

The width of the floor is 32 feet, which is equal to 8 inches in the scale drawing (32/4=8). So, the width of the scale drawing is 8 inches.

Therefore, the perimeter of the floor in the scale drawing is:

P = 2(length + width)

= 2(10 + 8)

= 2(18)

= 36 inches

hence, the perimeter of the floor in the scale drawing is 36 inches.

Answer:

The speed of the bus is 74.242 kilometers per hour.

Step-by-step explanation:

Let suppose that bus runs at constant speed and that speed is measured in kilometers per hour. Then, the speed of the bus ([tex]v[/tex]), in kiometers per hour, is determined by following kinematic expression:

[tex]v = \frac{s}{t}[/tex] (1)

Where:

[tex]s[/tex] - Travelled distance, in kilometers.

[tex]t[/tex] - Time, in hours.

If we know that [tex]s = 2.45\,km[/tex] and [tex]t = 0.033\,h[/tex], then the speed of the bus is:

[tex]v = \frac{s}{t}[/tex]

[tex]v = 74.242\,\frac{km}{h}[/tex]

The speed of the bus is 74.242 kilometers per hour.

Answer:

[tex]x = 1[/tex]

Step-by-step explanation:

Given

[tex]|\frac{1}{3} - \frac{x}{4}| = \frac{7}{12}[/tex]

Required

Show solution on number line

Take LCM

[tex]|\frac{4 - 3x}{12}| = \frac{7}{12}[/tex]

Rewrite as:

[tex]\frac{1}{12}|4 - 3x| = \frac{7}{12}[/tex]

Multiply through by 12, we have:

[tex]|4 - 3x| = 7[/tex]

Remove the sign of absolute value

[tex]4 - 3x = 7[/tex] or [tex]4 - 3x = -7[/tex]

[tex]-3x = 7 - 4[/tex] or [tex]-3x = 4 - 7[/tex]

[tex]-3x = 11[/tex] or [tex]-3x = -3[/tex]

[tex]x = \frac{-11}{3}[/tex] or [tex]x = 1[/tex]

Since x is an integer, then:

[tex]x = 1[/tex]

R1019.40

Step-by-step explanation:

100% = 1200

1% = 1200 ÷ 100 = 12

15.05% = 12 x 15.05 = 180.60

1200 - 180.60 = 1019.40

Answer:

x = 1000

Step-by-step explanation:

5,350 ÷ x = 5.35

To find this you should divide 5,350 by 5.35.

5,350 ÷ 5.35 = 1000

x = 1000

Answer:

5.35

Step-by-step explanation:

Divide 5,350 by 5.35

[tex]5350 \div 5.35[/tex]

you'll get 1000

Check your answer by dividing 5350 by 1000

[tex]5350 \div 1000 = 5.35[/tex]

Answer:

Rs 300000

Step-by-step explanation:

Given that,

Length of a rectangular park, l = 150 m

Breadth, b = 100 m

We need to find the cost of fencing the park at the rate of 20 per metre. The area of a rectangle is given by :

A = lb

So,

[tex]A=150\times100\\\\A=15000\ m^2[/tex]

Cost of fencing,

[tex]C=15000\times 20\\\\C=Rs\ 300000[/tex]

So, the required cost is Rs 300000.
