Write an expression for the calculation double 2 and then add5

1 answer:

5 0

So,

"double 2"
2(2)

"add 5"
+ 5

Therefore, the whole expression would be:
2(2) + 5

If you wanted to evaluate it, it would come out like this.
4 + 5
9

18% of the the students at a school are in year 8 and 16% of the students are in year 9. If the school has 126 tera 8 students,

yarga [219]

Answer:

112

Step-by-step explanation:

The general form of all percentage questions is: the chunk= (some percentage) (of the whole), or c=p*w

We know that 18% of students are 8th grade and that is 126 students, so p = 0.18 and c=126 (126 students are 18% of the whole school)

126 = (0.18)w, divide both sides by 0.18

126/(0.18) = w = 700

9th graders are 16% of the school or 16% of 700 students

c = (0.16) 700 = 112 students

Law of sines: StartFraction sine (uppercase A) Over a EndFraction = StartFraction sine (uppercase B) Over b EndFraction = StartF

vladimir2022 [97]

Answer:

30°

Step-by-step explanation:

Law of Sines = $\frac{a}{Sin A} = \frac{b}{Sin B} = \frac{c}{Sin C}$

$\frac{2}{Sin 30} = \frac{2}{Sin B}$

$\frac{2}{Sin 30} = \frac{2}{Sin 30}$

Therefore, m∠B = 30°

Hope that's right and helps

For each of the following, decide if the given series is a geometric series. A. 5+25x+125x2+625x3+3125x4+⋯ : Is this a geometric

Westkost [7]

Answer:

A. Yes.

B. Yes.

C. No.

Step-by-step explanation:

A. Yes. The sum of the series, $5 + 25x + 125x^{2} + 625x^{3} + 3125x^{4} + ...........$ is the sum of a geometric series.

The first term of the series $a_n$ = 5.

The common ration or the ratio between successive terms (r) = $\frac{25x}{5} = 5x$ (Answer)

B. Yes. The sum of the series, $5x^{7} + 5x^{8} + 5x^{9} + 5x^{10} + ............$ is also the sum of a geometric series.

The first term of the series $a_n = 5x^{7}$ .

The common ration or the ratio between successive terms (r) = $\frac{5x^{8} }{5x^{7} } = x$ (Answer)

C. No. The sum of the series, $5 + 5x + 5x^{2} + 5x^{4} + 5x^{8} + ...........$ is not the sum of a geometric series.

The first term of the series $a_n = 5$ .
