(This is more like science!) the question is : According to the diagram below in what direction will the motion of the book go?

A theater has 49 seats in the first row 52 seats in the second row 55 seats in the third row how many seats are in the 16th row

devlian [24]

Answer:

94 seats

Step-by-step explanation:

We solve using Arithmetic sequence formula

an = a + (n + 1)d

Where

a = First term = 49

d = Common difference = 52 - 49 or 55 - 52 = 3

n = 16th row

Hence,

a16 = 49 + (16 - 1)3

a16 = 49 + (15 × 3)

a16 = 49 + 45

a16 = 94

Therefore, the number of seats on the 16th row is 94 seats

Which statements must be true?

Lorico [155]

Take a look at the picture and note that the same tick marks represent that they are congruent parts.

A. UV is parallel to JL. Yes, this is correct. They are parallel because they don't intersect at any point.

B. UW = 12KL. This is incorrect. The truth is, UW = (1/2)(KL). If this is a typo error and there should've been a '/' in between 1 and 2, then this is acceptable.

C. UW = VW. As you can see, UKVW is a rectangle. They have two pairs of congruent sides. And UW≠VW, so this is incorrect.

D. UV = UK. The diagonal of a rectangle is never equal with one of its sides. So, this is incorrect.

E. JK = 2VW. Since VW=UK and we can see that twice the length of UK is equal to JK, then this is correct.

1. -28 = -3n + 5 what is n?? 2.5−n3=−4

STatiana [176]

Answer:

1.

n=11

2.

$n = \sqrt[3]{9}$

Step-by-step explanation:

Question 1:

The given equation is:

$- 28 = - 3n + 5$

Subtract 5 from both sides:

$- 28 - 5 = - 3n$

$- 33 = - 3n$

Divide boy sides by:

-3

$n = \frac{ - 33}{ - 3} = 11$

Question 2:

The given expresion is :

$5 - {n}^{3} = - 4$

Subtract 5 from both sides

$- {n}^{3}= - 4 - 5$

This implies that;

$- {n}^{3}= - 9$

${n}^{3}= 9$

$n = \sqrt[3]{9}$

Hassan built a fence around a square yard. It took 48 m^2 of lumber to build the fence. The fence is 1.5 meters tall.

Gennadij [26K]

Answer:

Step-by-step explanation:

Please check ones more because this might be incorrect.

The area is in square meters...Let's change it

Square 48= 48*48 =2304

2304 divided by 4( 4 since the formula for the area of a sqaure is s*s and square has 4 sides)

2304 divided by 4 = 576

The formula for area of a square is S*S(side times side)

Let's apply the formula here.

so, 576 times 576

331776 square meters

Hope this is right and helps! :)

( This just my point of view. Please check this onces again)

Which is a perfect square a. 6^1 b. 6^2 c. 6^3 d. 6^5 (need answer now pls)

Bas_tet [7]

Hello there! 6^1 is not a perfect square. It's basically it's own number and 6 is not a perfect square. Therefore, A is out. 6^3 (216) is cubed, not squared, so C is out as well. Just by looking at the exponents, 6^2 is squared and 36 is a perfect square, so the answer is B: 6^2.
