Answer:

90°-24°=66°

Step-by-step explanation:

Because a right angle is always a 90 degree angle!!

Answer:

+1

Step-by-step explanation:

Well (+) and (-) is equals basically to (-) when add ing them or multiplying them... so the difference is +1

Supplementary angles - Sum = 180°

X + Y = 180°

x = larger angle

y = smaller angle

x = 2y - 60

x + y = 180

x = 180 - y

2y - 60 = 180 - y

2y - 60 -180 + y

3y = 240

y = 80°

x+y = 180

x+80° = 180°

x = 100°

Answer:

42.57

Step-by-step explanation:

we know,

mean = sum of the terms / no. of the terms

now,

10 + 39 + 71 + 39 + 76 + 38 + 25 /7

298/7 = 42.57 ans. (approx.)

therefore, approximate mean of the given numbers are 42.57.

Answer:

The period T (in seconds) of a pendulum is given by T=2\pi \sqrt((L)/(32)), where L stands for the length (in feet) of the pendulum. If \pi =3.14, and the period is 1.57 seconds

Step-by-step explanation:

i am smart

The length of the pendulum is 128 feet.

Time period of a pendulum is defined as the time taken by the pendulum for completing one oscillation.

Here,

Given that,

Time period of the pendulum,

T = 2[tex]\pi[/tex] √(L/32)   where L is the length of the pendulum(in feet)

T² = 4[tex]\pi[/tex]²(L/32)

T²/4[tex]\pi[/tex]² = L/32

So, L = 32 xT²/(4[tex]\pi[/tex]²)

L = 8T²/[tex]\pi[/tex]²

So, putting the value of time period, T = 12.56 s

Length of the pendulum,

L = 8T²/[tex]\pi[/tex]²

L = 128 feet

Hence,

Length of the pendulum is 128 feet.

Your question was incomplete, but most probably will be:

The period T (in seconds) of a pendulum is given by T=2\pi \sqrt((L)/(32)), where L stands for the length (in feet) of the pendulum. If \pi =3.14, and the period is 12.56 seconds, what is the length?

Step-by-step explanation:

1 week = 7 days of 24 hours each = 7×24 = 168 hours.

the first team can do 1/700 of the total work per hour.

the second team can do 1/600 if the total work per hour.

if they work together, then 1/700 + 1/600 of the total work can be done per hour.

to add these 2 fractions we need to bring them to the same denominator. and that would be 4200 (LCM of 700 and 600).

1/700 + 1/600 = 6/4200 + 7/4200 = 13/4200

so, together, they can do 13/4200 if the total job in 1 hour.

how many hours will they need together to finish the job ?

well, how often does 13 fit into 4200 (as 4200/4200 is the complete job) ?

4200 / 13 = 323.0769231... hours

so, it will still take a little bit over 323 hours to clean all the streets.

but there are only 168 hours until the film crew starts.

so, no, there is not enough time.

Answer:

66,667

Step-by-step explanation:

We are given this chart to complete.

0            _______      ________   40,000          _______      _______

0%             20%            40%             60%                80%            100%

We see that 60% corresponds to 40,000. That means that since 20% is 1/3 of 60%, then the number corresponding to 20% is 1/3 of 40,000.

40,000/3 = 13,333

40% is twice 20%, so corresponding to 40%, you must have 2 × 13,333.

For 40%, you write 26,667.

80% is 4 times 20%, so for 80%, you write 4 × 13,333 = 53,333.

Finally, 100% is 5 times 20%, so for 100%, you write 5 × 13,333 = 66,667.

0          _13,333_    _26,667_   40,000       _53,333_    _66,667_

The equation of the table is a linear function; which has a constant rate of change

The equation is given as:

y = 2x + 3

When x = -2, we have:

[tex]y = 2 * -2 + 3 = -1[/tex]

When x = 0, we have:

[tex]y = 2 * 0 + 3 = 3[/tex]

When x = 1, we have:

[tex]y = 2 * 1 + 3 = 5[/tex]

When x = 3, we have:

[tex]y = 2 * 3 + 3 = 9[/tex]

So, the complete table is:

x  -2  -1  0  1  2  3

y   -1   1  3   5  7  9

We know that:

Solution:

Hence, the value of x is 75°

The reflection across the line y = x gives A'(6, -2), B'(3, -3), C'(-1, 1) and D'(5, 2)

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.

If a point A(x, y) is reflected along the line y = x, the new point would be at A'(y, x)

The vertex of the quadrilateral is at A(-2, 6), B(-3, 3), C(1, -1) and D(2, 5). The reflection across the line y = x gives A'(6, -2), B'(3, -3), C'(-1, 1) and D'(5, 2)
