4 0

Answer:

Step-by-step explanation:

This is an Arithmetic Series with common difference 4 and first term 3

so the nth term an = 3 + (n -1)4

= 4n - 1.

The sum of n terms

= n/2 (a1 + L)

= n/2(3 + 1671)

= 837n.

There are (1671-3) / 4 + 1 = 418 terms in the series,

so the total value of the series is 837*418

= 349,866.

I will give Brainliest its maths and I need help on a b and c

JulsSmile [24]

Answer:

${5}^{3} \times {5}^{x} = {5}^{7} \\ 3 + x = 7 \\ x = 4$

$( {q}^{2} )^{y} = {q}^{6} \\ 2y = 6 \\ y = 3$

${1000}^{m} \div {100}^{n} = {10}^{z} \\ \frac{1000 ^{m} }{ {100}^{n} } = {10}^{z} \\ \\ {10}^{m - n} = {10}^{z}$

Can I have the brainliest please?

Find the measure of angle Y

Musya8 [376]

Answer:

∠y=60°

Step-by-step explanation:

Question says to find the measure of the angle Y.

We have been given a picture of triangle XYZ. All angles are marked with same sign so that indicates that all three angles are equal.

∠x = ∠y = ∠z...(i)

We know that sum of all three angles of the triangle is always 180°.

So we can write:

∠x+∠y+∠z=180°

∠y+∠y+∠y=180° {using equation (i) }

3∠y=180°

divide both side by 3

∠y=60°

Hence final answer is the measure of angle y is 60 degree.
