someone please solve this please, thank you so much

Answer:

Step-by-step explanation:

The drum solo begins a third of the way into the song which lasts 2.5 minutes.

The drum solo therefore starts at:

= 2.5 * 1/3

= 0.83 minutes

Translate that to seconds by multiplying by 60:

= 0.83 * 60

= 50 seconds

Solo begins at 50 seconds in and lasts for 24 seconds:

= 50 + 24

= 74 seconds or

= 1 minute 14 seconds

Answer:

The percent of students that are non-believers that did write their name is 2%.

Step-by-step explanation:

Given that a school took a survey of its students regarding climate change, and among the students, 80% believed that greenhouse gases were responsible for climate change, while of the remaining students, 60% still believed that climate change was real and 75% of the non-believers did not write their name on the survey, to determine what percent of students are non-believers that did write their name, the following calculation must be performed:

100 - 80 = 20

1 - 0.6 = 0.4

1 - 0.75 = 0.25

20 x 0.4 x 0.25 = X

8 x 0.25 = X

2 = X

Therefore, the percent of students that are non-believers that did write their name is 2%.

35kg - 3500g

3500g - 2500g

= 1000g

Answer:

1 : 14

Step-by-step explanation:

The measures must have the same units, that is both g or Kg

2500 g : 35 Kg

= 2500 g : 35000 g ( 1 Kg = 1000 g )

Divide both parts by 100

= 25 : 350 ( divide both parts by 25 )

= 1 : 14

Answer:

  113.1 m²

Step-by-step explanation:

The surface area of the cone is ...

  SA = πr(r +s) . . . . . . where r is the radius and s is the slant height

  SA = π(4 m)(4 m + 5 m) = 36π m² ≈ 113.1 m²

The surface area is about 113.1 m².

Answer:

2.33

Step-by-step explanation:

imagine a circle. its center is A, and it goes through B, so its radius is AB.

then it is important to know that the sum of all the angles in a triangle is 180 degrees.

one angle (at C) is 90. the angle at B is 25. so, the angle at A is 180 - 90 - 25 = 65 degrees.

more back to our circle.

in this circle the line CB is the sine of the angle at A multiplied by the radius.

and AC is the cosine of the angle at A multiplied by the radius.

we can ignore the orientation + and - of these functions, as we are only interested in the absolute length (and we can mirror the triangle, and all the angles and side lengths still stay the same).

=> CB = sin(A)×AB

AC = cos(A)×AB

=> 5 = sin(65)×AB

=> AB = 5 / sin(65)

=> AC = cos(65)×5/sin(65) = 5 × (cos(65)/sin(65)) =

= 5 × cot(65) = 2.33

Answer:

24/10

Step-by-step explanation:

From the diagram

Opposite BC = 24cm

Adjacent = AC = 10cm

tan theta = opposite/adjacent

Substitute

tan <A = BC/AC

tan <A = 24/10

Hence the equivalent ratio is 24/10

Answer:

572.4 m

Step-by-step explanation:

Fórmula del ángulo de elevación =

tan θ = Opuesto / Adyacente

θ = 3 °

Opuesto = 30 m

Adyacente =?

Por eso

bronceado 3 = 30 m / x

Multiplicar cruzada

bronceado 3 × x = 30 m

x = 30 m / bronceado 3

x = 572.43410063m

Aproximadamente = 572.4 m

Answer:

I think that it would be 100^(0.085)

Answer:

A) 145.3 cm^2

Step-by-step explanation:

The formula for the area of a circle is A = π r^2

So to find the area we would plug the radius of 6.8 into the formula

Area = π (6.8)^2

Area = (3.14) (6.8)^2

Area = 145.27

Area = 145.3

Answer:

D is the answer for the question

Answer:

8

Step-by-step explanation:

Let the next number be x

'taking half the number to get the next number. is expressed as;

1/2 of 16 = x

x = 1/2 *16

x = 16/2

x = 8

hence the next number will be 8

½ ton ==> 8 sq. yards

so, each sq. yard needs ½ ÷ 8 = 1/16 ton

Answer:

GD = 5/2 sqrt 2 = 2½ sqrt 2

EG = 5/2 sqrt 6 = 2½ sqrt 6

Answer:

7/32

Step-by-step explanation:

John and George together raked 7/8 of the yard. John raked 3/4 of that amount. What part of the yard did john rake?

Proportion of the yard Jake raked = 7/8 x 3/4 = 21/32

Portion of the yard Jake raked = 21/32 - 7/8 = 7/32

this is 90 60 30 formula for example

90 meet 2x

30 meet x

and

60 meet x√3

so 90 meet 5

30 meet 5/2=2.5

and 60 meet 2.5√3

so the answer is 2.5

Answer:

2.5

Step-by-step explanation:

[tex]\sin 30\degree = \frac{x}{5}\\\therefore x = 5\sin 30\degree\\\therefore x = 5 \times \frac{1}{2}\\\therefore x = 2.5[/tex]
