The general term of a sequence is given by an = 7+3 (n − 1) for n > 1.

Mathematics
1 answer:
Firdavs [7]3 years ago
3 0

Answer:

The fifth term is 8.

Step-by-step explanation:

Give n=5 in the general term

T 5=3(5)-7 = 15–7 =8

Another method

Tn = 3n - 7

T 1 = 3(1)-7 = -4

T 2 = 3(2) -7= -1

d= t 2 - t 1 = -1 -(-4)=3

a = -4 d=3

Tn = a + (n-1)d =

T 5 = a + (5–1)d = a +4 d = -4 +4(3)= 8

Serhud [2]

Answer: 16

Step-by-step explanation:

100% is 64 and 1% of 64 is 6.4 and if you multiply 6.4 times 25 is 160 so 125% is 160 so 90% of 160 is 144 so 160-144 is 16

What is<br> 3% of [(-0.5) * (- :)]<br> ?
expeople1 [14]
Solution for 0.5 is what percent of 3:

0.5:3*100 =

(0.5*100):3 =

50:3 = 16.666666666667

Now we have: 0.5 is what percent of 3 = 16.666666666667

Question: 0.5 is what percent of 3?

Percentage solution with steps:

Step 1: We make the assumption that 3 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$x​.

Step 3: From step 1, it follows that $100\%=3$100%=3​.

Step 4: In the same vein, $x\%=0.5$x%=0.5​.

Step 5: This gives us a pair of simple equations:

$100\%=3(1)$100%=3(1)​.

$x\%=0.5(2)$x%=0.5(2)​.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{3}{0.5}$
100%
x%​=
3
0.5​​

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{0.5}{3}$
x%
100%​=
0.5
3​​

$\Rightarrow x=16.666666666667\%$⇒x=16.666666666667%​

Therefore, $0.5$0.5​ is $16.666666666667\%$16.666666666667%​ of $3$3​.

A triangle has two sides measuring 10 inches and 16 inches. The angle opposite the 16-inch side measures 68.9°. Solve the triang
Nezavi [6.7K]

Answer:

measure of two unknown angles are 35.7° and 75.4°

measure of one unknown side is 16.6 inches

Step-by-step explanation:

i used law of sines to find the angle opposite 10 inch side

sin 68.9/16 = sinФ/10

Ф = 35.7°

then is added 35.7 and 68.9 and subtracted the sum from 180° to get the measure of the third angle, 75.4°

i used law of sines again to find the measure of the third side

sin 68.9/16 = sin 75.4/x

x = 16.59
