How many terms of the arithmetic progression 2,5,8..Must be taken to get a sum of 392?​

Answers

Answer 1

Answer:

Number of term = 48

Step-by-step explanation:

GIven:

Arithmetic progression

2,5,8..

Total sum of Arithmetic progression is 392

Find:

Number of term

Computation:

First term a = 2

Difference d = 5 - 2 = 3

Sn = [n/2][2a + (n-1)d]

392 = [n/2][2(2) + (n-1)3]

392 = [n/2][4 + 3n - 3]

784 = [n][1 + 3n]

784 = n + 3n²

3n² + n - 784

n = 48 , n = -49

Number of term = 48

The American National Standards Institute specifications state that the
maximum slope of a wheelchair ramp should be one twelfth i.
The new ramp measures 5 feet high at its highest point and stretches
50 feet horizontally. Will this ramp pass specifications?

Answers

Answer:

No.

Step-by-step explanation:

Given that :

Maximum accepted Ramp slope = 1/12

A new ramp with :

Height range = 5 feets

Horizontal stretch = 50 feets

Th slope = Rise / Run = Height range / horizontal stretch = 5 / 50 = 1 / 10

1 / 10 > 1 / 12

This means the new ramp's slope is greater than than the maximum slope specification ; and hence not acceptable

[tex]\frac{3}{3}[/tex]=[tex]\frac{x+3}{13}[/tex]

Solve by cross multiplying

13×3=39

3(x+3)=3x+9

3x+9=39

3x=30

x=10

Answer:

x=10

Step-by-step explanation:

Assuming that the triangles are similar to each other, you can set up ratios

[tex]\frac{3}{3}=\frac{13}{x+3}[/tex]

since 3/3 is 1 and we know that anything other than 0 over itself is 1, we can deduce that x=10

Yanni read 24 pages of
a book. One third of the book is
still left to read. How many
pages are there in the
whole book?

Answers

Answer:

36 pages

Step-by-step explanation:

If one third of the book is left to read until completion, then Yanni has read two thirds of the book so far.

24 pages is equal to two thirds, so one third will be half of this; 12 pages.

The whole book is three thirds, so 12 * 3, which is 36 pages

Can someone help me solve this geometry problem down below?

Answers

Answer:

x = 29

Step-by-step explanation:

Given that both triangles are congruent to each other, therefore, their corresponding angles are congruent as well. This means all three angles in one is the same as all three corresponding angles of the other.

Therefore:

m<CAB = m<CDE = 74°

m<ABC = 2x (given)

m<BCA = 48° (given)

Thus:

m<CAB + m<ABC + m<BCA = 180° (sum of triangle)

Substitute

74 + 2x + 48 = 180

Add like terms

2x + 122 = 180

2x + 122 - 122 = 180 - 122

2x = 58

2x/2 = 58/2

x = 29

A pooled variance is an estimated weighted variance made up of several different populations when the mean of each population may be different, but one may assume that the variance of each population is the same.

a. True
b. False

Answers

Answer:

True

Step-by-step explanation:

Considering the above definition of Pooled Variance, the correct answer is TRUE.

This is because Pooled variance is used to determine the reasonable estimates of variance, where several repeated tests are expected at each value.

Allen earns $7 an hour to wait tables at a restaurant. In addition, he makes an $8 tip from each
table. He waited 6 tables and made $104. Which equation(s) below could be used to find the
total number of hours he worked? How many hours did he work?

Answers

Answer:

he worked 8 hours

Step-by-step explanation:

104= 8 x 6 + 7x

104= 48 + 7x

56= 7x

x=8

104 - 48= 56

56/7

Answer:

Equation - 7h + 8t = $104

Hours Worked = 8

Step-by-step explanation:

First, let's create an equation!

7h + 8t = $104 (Our variables are h = # of hours, and t = # of tables)

Now, we have to input what we know! We know that Allen worked 6 tables.

7h + 8(6) = $104

and finally we can solve this equation!

7h + 48 = $104

     -48     -48

7h = 56

÷7    ÷7

h = 8

In conclusion, Allen worked 8 hours!

Step-by-step explanation:

Both angles ABC and CBD are complementary, that is, the sum of the measures of both angles equals 90°, that is:

[tex]\angle ABC + \angle CBD = 90^{\circ}[/tex] (1)

If we know that [tex]\angle ABC = 5\cdot x[/tex] and [tex]\angle CBD = 4\cdot x[/tex], then the value of [tex]x[/tex] is:

[tex]5\cdot x + 4\cdot x = 90^{\circ}[/tex]

[tex]x = 10[/tex]

The value of [tex]x[/tex] is 10.

Answer:

  the first is two points; the second is the interval between (and including) those two points

Step-by-step explanation:

The equation ...

  4 = |x +5|

has two solutions:

  x ∈ {-9, -1}

__

In the interval between those two solutions the absolute value expression is less than 4. So, the second expression has a solution that is a range of values. Those values are in the interval whose boundaries are -9 and -1.

  x ∈ [-9, -1]

__

The solution to the second expression can be found as ...

  4 ≥ |x +5|

  4 ≥ x+5 ≥ -4 . . . . express as a compound inequality

  -1 ≥ x ≥ -9 . . . . . . subtract 5

__

The attached graph shows the two solutions. The solution to the first equation is the pair of (black) lines, x=-9 and x=-1. The solution to the second equation is the (orange) shaded interval -9 ≤ x ≤ -1.
