Answer:

24 square millimeters

Step-by-step explanation:

Area of a triangle is half of the base times the height.

[tex]\frac{1}{2} bh[/tex]

Here, that means

[tex]\frac{1}{2}[/tex](8)(6) = 24 square millimeters

Answer:

The length is 30 (which you aready said) and the width is 40

Step-by-step explanation:

1200/30=40

(another way)

120/30=4 (multiply each side by ten)

Answer:

Step-by-step explanation:

you actually dont have to do any division in this problem. since you know the area of the square and its depth, you simply multiply to two fractions, so [tex]\frac{25}{4} *\frac{8}{5}[/tex] when you multiply fractions all you do is multiply the tops and and bottoms, so 25 * 8=200 and 5 * 4=20, so the fraction is now 200/20, so when divide both sides by 20, the answer is 10. another way to demonstrate this in case you didnt understand is that you can rewrite your equation as [tex]\frac{25 * 8}{4 * 5}[/tex] then all you have to do is perform the opperation.

Answer:

12 = 3 + p

Step-by-step explanation:

She has a total of 12 pencils

3 of them are red

The rest are "p"

p + 3 must equal 12 because she has a total of 12 pencils consisting of 3 red and "p" as the rest

Answer:

the smaller square length is 3cm

the larger square length is 6cm

hence their ratio will be 3:6

Simplify the ratio

we have our final answer to be 1:2

The required ratio of the side length of the smaller square to the side length of the larger square is 1 : 2.

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

Here,
Side of smaller square, a = 3
Side of the larger square, b = 6

According to the question,

The ratio of the side length of the smaller square to the side length of the larger square,

= a / b = 3 / 6
= 1 / 2

Thus, the required ratio of the side length of the smaller square to the side length of the larger square is 1 : 2.

Answer:

a + b =  2

Step-by-step explanation:

Given

ax² + bx + c = 0 ( equation in standard form )

Then the sum of the roots = - [tex]\frac{b}{a}[/tex]

3x² - 6x + 2 = 0 ← is in standard form

with a = 3, b = - 6 , then

sum of roots = - [tex]\frac{-6}{3}[/tex] = 2

Answer:

[tex]I \ think \ it \ is \ 6x\\\\3x^2 - 6x +2 = 0\\\\[/tex]

[tex]x = \frac{-b \pm \sqrt{b^2 - 4*a*c} }{2a} \\\\a = 3, b = -6, c = 2\\\\x = \frac{-b + \sqrt{b^2 - 4*a*c} }{2a}, x = \frac{-b - \sqrt{b^2 - 4*a*c} }{2a} \\\\ \\\\x = \frac{6 + \sqrt{36 - 24} }{6} , x = \frac{6-\sqrt{36 -24} }{6} \\\\[/tex]

[tex]x = \frac{6+\sqrt{12} }{6} , x = \frac{6-\sqrt{12} }{6} \\\\x = \frac{3+\sqrt{3} }{3} , x = \frac{3-\sqrt{3} }{3}[/tex]

[tex]Let \ a = \frac{3 + \sqrt{3} }{3} , b = \frac{3-\sqrt{3} }{3} \\\\a + b = \frac{3+\sqrt{3} }{3} + \frac{3-\sqrt{3} }{3} = \frac{3+\sqrt{3} +3-\sqrt{3} }{3} = \frac{6}{3} = 2[/tex]

Answer:

0

Step-by-step explanation:

If you plug two points into the equation y2-y1/x2-x1, you will find the slope or rate of change. In this case I used the points (0,3) and (2,3). Plug them in to get 3-3/2-0. 0/2=0. Therefore, the rate of change is 0.  

If this helps please mark as brainliest

Answer:

0

Step-by-step explanation:

there is no rate of change. rate of change means what is the slope or the distance the beginning and end of the line. since it is going in a straight line there is no rate of change.

Answer:

[tex]\$14.16[/tex]

Step-by-step explanation:

Since the question implies a constant rate, we can set up the following proportion:

[tex]\frac{3}{5.31}=\frac{8}{x},\\3x=8\cdot 5.31,\\x=\frac{8\cdot 5.31}{3}=\boxed{\$14.16}[/tex]

3t = 5.31

t = 1.77

We're looking for 8t.

t = 1.77

8t = 14.16

Answer:(1,8)

Step-by-step explanation:

Answer:

C=9.42

Step-by-step explanation:

Formulas: C=2πr or C=πd

Were gonna use C=2πr

"r"stands for radius from the problem we know that the radius is 1.5 .

Now we substitute the "r" for 1.5, it looks like this C=2π1.5 .

Now we multiply 2x1.5=3 . Now you are left with C=3π

Now you need to multiply 3xπ (Instead of π use 3.14) it would look like this 3x3.14= 9.42

Answer:

The enrollment after 5 years is 10,724

Step-by-step explanation:

Generally, we can have the depreciation formula written as follows;

A = P(1 - r)^t

A is the number of enrollment in after a certain number of years t

P is the initial population which is 13,500

r is the rate of depreciation which is 4.5% = 4.5/100 = 0.045

t = 5 years

Substituting these values, we have it that;

A = 13,500(1-0.045)^5

A = 10,723.84

Step-by-step explanation:

Answer:

12.62

Step-by-step explanation:

imagine a circle with the center at the corner (let's call it A) with the 31 degree angle. the radius is AB.

so,

x = sin(31)×AB

and

21 = cos(31)×AB

therefore,

AB = 21/cos(31) = 24.4993...

=> x = sin(31)×24.4993... = 12.62 (12.61807...)

Answer:

[tex]X=-2.74*10^{-7}Rs[/tex]

Step-by-step explanation:

From the question we are told that:

Table for price per Kg

 Watermelon Rs 18.50

 Cherry Rs 72

 Grapes Rs 120.60

 Apples Rs 78.40

Karan Bought:

 412 kg watermelon

 1 kg 200g cherries

 250 g grapes

 134 kg apples

Generally the equation for Total Price of Fruits Bought is mathematically given by

\sum (Price Rs* Weight kg )

 [tex]\sum (P* W)=(412*18.5)+(1.2*72)+(0.25*120.60+(134*78.40))[/tex]

 [tex]\sum (P* W)=27374289.78[/tex]

Therefore the Amount of Money he gets back is

 [tex]X=500-\sum (P* W)[/tex]

 [tex]X=-2.74*10^{-7}Rs[/tex]

Therefore

He owes the shop keeper 2.74 million Rs

Answer:

(x + 8) (x - 8)

Step-by-step explanation:

To factorise the expression follow the steps:

Think the factorising means you want like:-

  ( x + _ ) ( x + _ )

Now, add the numbers to get 0 & multiple together to get -64

 -64 = 8 x -8

 8 + -8 = 0

Now fill the numbers in the factorising mean which will give you,

( x + _ ) ( x + _ ) --> ( x + 8 ) ( x - 8 )

Therefore, the answer will be: ( x + 8 ) ( x - 8 )

Answer:

1100 yd²

Step-by-step explanation:

The parking lot can be divided into 2 rectangles :

Area of a rectangle = Length * Width

First rectangle :

Dimension = 40 yards by 20 yards

Area = 40 * 20 = 800 yd²

Rectangule 2 :

30 yards by 10 yards

Area = 30 * 20

Area = 30 * 10 = 300 yd²

Total area of parking lot :

800 + 300 yd²

= 1100 yd²
