Please help me :((( it’s geometry
NikAS [45]

\tt Step-by-step~explanation:

\tt Area:

To solve for the area of a triangle, we multiply the length and height, then divide that by two. L = 10. H = 7.

\tt 10*7=70\\70/2=35\\35=A

\tt Perimeter:

\tt Step~1:

To solve for the perimeter, or edges, of the triangle, we need to use the Pythagorean Theorem: a² + b² = c² to solve for the third side. We already know two measures: 10 and 7. Now we need to square them, add them together to get c², then take the root of that number.

\tt 7^2=49\\10^2=100\\100+49=\sqrt{149}\\\sqrt{149

We cannot simplify √149, so we either leave it, or round it.

\tt \sqrt{149}\\12.2066

This is rounded to the nearest 10,000.

\tt Step~2:

Now that we have the measure of the longest side, we can add all three sides together to get the perimeter of the triangle.

\tt 10+7+\sqrt{149}=17+\sqrt{149}=P\\Rounded~to~the~nearest~1,000th:~29.207=P

\large\boxed{\tt Our~final~answer: ~A=35,~P=17+\sqrt{149}}

Gnom [1K]

Answer:

456 chairs

Step-by-step explanation:

If there are 6 round tables with 7 chairs each you would multiply 7, 6 times (7 x 6) = 42

If there are 23 rectangular tables with 18 chairs each you would multiply 18, 23 times. ( 18 x 23) = 414

Then you add up all the chairs, 456 chairs total.

If I'm wrong I'm so sorry

if I'm right Thank you (brainliest plz)

Who can help me with this
Lady bird [3.3K]

Answer:

Growth

Step-by-step explanation:

Given

\frac{2}{3}(2.5)^x

Required

Growth or decay

The general form is:

y = ab^x

Such that:

b = rate

For b, we have the following conditions:

b > 1 ----- Growth

0 --- Decay

b = 1 ---- None

Compare \frac{2}{3}(2.5)^x to y = ab^x

b = 2.5

<em>Because 2.5 > 1, then the first condition applies (growth)</em>

A company has 6582 to give out in bonuses. An amount is to be given out equally to each of 32 employees A manger Jake has reason
just olya [345]

Answer:

His estimate is not correct

Each employee gets 205.6875

Step-by-step explanation:

Bonus to give out = 6582

Number of employees to get bonus = 32

Bonus per employee = Total bonus / number of employees

= 6582 / 32

= 205.6875

Each employee will get 205.6875 contrary to manger Jake reasoning of 2000 per employee

manger Jake reasoning

6572 / 32

32 in 65 = 2 remainder 1

He added 000 zeros to 2 which is wrong

He should have added 00 zeros to 2 because he has 172 remaining after dividing 65 by 32
