 Your answer would be x = 3.0645

CHECK
log (3.0645 + 1) ?=? -(3.0645)2 + 10
log 4.0645 ?=? -9.3912 + 10
0.609 ?=? 0.609

Hope this helps!

So in short your answer is x = 3.0645

Finding missing angles
Bingel [31]

Answer:

D)

Step-by-step explanation:

Since we see the whole angle is 90° and it's split into two smaller angles, 7x° and 11x°, then we can conclude that 7x°+11x°=90°

*And x=5

Three friends said their heights were 5 and start fraction 13 over 30 end fraction feet, 5 and one-sixth feet, and 5 and start f
KengaRu [80]

Answer:

5\frac{1}{6} < 5\frac{13}{30} < 5\frac{68}{90}

Step-by-step explanation:

Represent the friends with A, B and C

A = 5\frac{13}{30}

B = 5\frac{1}{6}

C = 5\frac{68}{90}

Required

Order from least to highest

First, we convert the given parameters to decimal

A = 5\frac{13}{30}

A = 5 + \frac{13}{30}

A = 5 + 0.43

A = 5.43

B = 5\frac{1}{6}

B = 5 + \frac{1}{6}

B = 5 + 0.17

B = 5.17

C = 5\frac{68}{90}

C = 5 + \frac{68}{90}

C = 5 + 0.76

C = 5.76

So, we have:

A = 5.43      B = 5.17      C = 5.76

Order from least to greatest

B = 5.17       A = 5.43          C = 5.76

Replace them with the original values

B = 5\frac{1}{6}       A = 5\frac{13}{30}      C = 5\frac{68}{90}

Hence, the correct order is:

5\frac{1}{6} < 5\frac{13}{30} < 5\frac{68}{90}

Please help with this
Free_Kalibri [48]

Answer:

S_{25}=555

Step-by-step explanation:

Given that,

In an AP, the 6th term is 39 i.e.

a_6=a+5d\\\\39=a+5d\ ....(1)

In the same AP, the 19th term is 7.8 i.e.

a_{19}=a+18d\\\\7.8=a+18d\ ......(2)

Subtract equation (1) from (2).

7.8 - 39 = a+18d - (a+5d)

-31.2 = a +18d-a-5d

-31.2 = 13d

d = -2.4

Put the value of d in equation (!).

39 = a+5(-2.4)

39 = a- 12

a = 39+12

a = 51

The sum of n terms of an AP is given by :

S_n=\dfrac{n}{2}[2a+(n-1)d]

Put n = 25 and respected values,

S_{25}=\dfrac{25}{2}[2(51)+24(-2.4)]\\\\=555

Hence, the sum of first 25 terms of the AP is equal to 555.

Answer:

A=45 square inches

Step-by-step explanation:

First find the height using Trig

Tan(45)=x/6

x=6tan(45)

x=6

Then area of a parallellogram is base x height so

A=7.5 x 6

A=45 square inches
