Answer:

Age of Nicole x= 24 years

Age of Donald = y = 48 years

Step-by-step explanation:

Suppose x represents Age of Nicole in years and y represents age of Donald in years

Sum of their ages is 72, therefore

[tex]x+y=72[/tex] -------------- (1)

Nicole is half as old as Donald

[tex]x= \frac{y}{2}[/tex]   ------------------ (2)

Substitute x=y/2 in equation (1)

[tex]\frac{y}{2} +y = 72 \\3y = 2(72) \\y = \frac{144}{3} \\y= 48 \ years[/tex]

Now put y=48 in equation (2)

[tex]x =\frac{48}{2} \\x=24[/tex]

Answer:

Step-by-step explanation:

[tex]cot(\frac{\pi }{2} -\theta)=tan \theta=-0.87[/tex]

or second method

[tex]\cot(\frac{\pi }{2} -\theta)=\frac{1}{\tan(\frac{\pi }{2} -\theta)} =\frac{1}{\frac{\tan\frac{\pi }{2} -\tan \theta}{1+\tan \frac{\pi }{2 } \tan \theta} } =\frac{1+\tan\frac{\pi }{2} \tan \theta}{\tan\frac{\pi }{2} -\tan \theta} \\(divide~the~numerator~and~denominator~by~\tan\frac{\pi }{2} )[/tex]

[tex]=\frac{\cot\frac{\pi }{2} +\tan\theta}{1-\cot\frac{\pi }{2} \tan\theta} \\=\frac{0+\tan \theta }{1-0*\tan\theta} \\=\tan \theta\\=-0.87[/tex]

Answer:  20% of the teachers are from district M

There are 50 teachers from district M, so bar M is 50 units tall.

=======================================================

Work Shown:

Let's add up the bar heights of the bars shown in the chart.

J+K+L+N = 50+80+30+40 = 200

So 200 teachers are from districts J,K,L, or N.

We're told that 250 total teachers attended. This must mean M = 50. We're effectively solving 200+M = 250.

So you'll need to draw a bar over M such that it is 50 units tall. This will complete the chart.

Because there are 50 teachers from district M, out of 250 total, we can then compute the percentage to get

50/250 = 0.20 = 20%

So 20% of the teachers are from district M.

Answer:

x = 20 units

Step-by-step explanation:

Using the Altitude- on- Hypotenuse theorem

( leg of Δ SRQ )² = (part of hypotenuse below it ) × ( whole hypotenuse ), so

x² = 16 × (16 + 9) = 16 × 25 = 400 (take the square root of both sides )

x = [tex]\sqrt{400}[/tex] = 20

Answer:

The answer is 60%

Step-by-step explanation:

12+8 = 20

12/20 = 0.6

Answer:

12/10=1.2

Step-by-step explanation:

You just move the decimal one place value to the left. so 12÷10=1.2 which is the same as 12/10=1.2

Answer:

12/10

I'm pretty sure that's the answer

Answer:

draw diameter of the circle

The option second “with compass point at A, construct an arc of length OA intersecting the circle” is correct.

It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)

To construct a regular hexagon in Circle O first mark point A then, with compass point at A, construct an arc of length OA intersecting the circle.

Thus, the option second “with compass point at A, construct an arc of length OA intersecting the circle” is correct.

#SPJ2

Answer:

1.7%

Step-by-step explanation:

Simple interest (I) is calculated as

I = [tex]\frac{PRT}{100}[/tex] ← substitute values for I, P and T

17 = [tex]\frac{500(2)R}{100}[/tex] ( multiply both sides by 100 to clear the fraction )

1700 = 1000R ( divide both sides by 1000 )

1.7 = R

The rate of interest is 1.7%

Answer:

The speed would be 60kph.

Answer:

80 mph (average)

Step-by-step explanation:

Split 120 into thirds, each one being half an hour.

120/3=40

Add two of them together, getting 80.

40x2(or 40+40)=80

Since the car travels 80 miles in one hour, 80 mph is the average speed.

Answer:

10-2

Step-by-step explanation:

El número 10 y 2 tienen la diferencia de 8.

Answer:

let x be cost of a hotdog

let y be cost of hamburger

so,

5x + 4y = 17.75                    eq. 1

4x + 5y = 18.25                    eq. 2

manipulate eq. 1 so solve for x:

5x = 17.75 - 4y

x = 17.75/5 - (4/5)y

x = 3.55 - (4/5)y                  eq. 3

substitute eq. 3 to eq. 2:

4(3.55 - (4/5)y) + 5y = 18.25

14.2 - (16/5)y + 5y = 18.25

14.2 + (9/5)y = 18.25

(9/5)y = 18.25 - 14.2

4.05= (9/5)y

y = 2.25

x = 3.55 - (4/5)(2.25)

x = 1.75

hotdog costs $1.75

hamburger costs $2.25

Answer:

66

Step-by-step explanation:

angle 1 and 4 are supplementary so the 2 added together equal 180. 180-124=56.

The sum of the triangles angles equal 180

180-56-58=66 which is the value of angle 2

Answer:

you have to change the 145* to 110* and flip it to the idol point in x

Step-by-step explanation:

hope this helps, I was just doing this

Answer:

The polygon is a pentagon and it has 5 sides so use the formula to find the sum of the interior angles that is (n-2)×180°.so,

(5-2)×180 = 540°

540-145-110-105-100 = 80°

so the answer is 80°
