Find the area of a triangle with base of 10 inches and a height of 5 inches.
100 square inches
B 50 square inches
C) 25
square inches
D 12.5 square inches

Step-by-step explanation:

1. We need to find the value of 8.1 × 10³ − 2.4 × 10² in standard form.

We can also write its as :

8.1 × 10³ − 2.4 × 10²

81000 − 240

Standard form = 80760

2.

Amy's weight = 40 kg

Blood comprises 8% of the weight of a human.

Weight of her blood,

[tex]W=8\%\ of\ 40\\\\=\dfrac{8}{100}\times 40\\\\=3.2\ kg[/tex]

So, the weight of her blood is equal to 3.2 kg.

Answer: 7/25 or 28%

Step-by-step explanation:

28 (cherry) + 19 (strawberry) + 20 (orange) + 33 (lemon) = 100 (total)

so p(cherry), or the probability of getting cherry, is 28/100 (7/25)

that as a percent is 28%

khan

Answer:

A= 24

Step-by-step explanation:

First find the scale factor. so the scale factor for these two triangles is 1.5.

21 / 14 = 1.5

18 / 12 = 1.5

So you are going to multiply 16 x 1.5

That will give you 24.

Answer:

-3/4-x=5/6

x=-3/4-5/6

x=-3*6-5*4/6*4

x=-18-20/24

x=-38/24

x=-19/12

stay safe love u

btw can i get brainliest

Answer:

-5/3 - x = 5/6

-x = 5/6 +5/3

-x/-1 = (5/2)/-1

therefore x = -5/2

therefore -5/2 must be subtracted

Answer:

area = 72 yd²

Step-by-step explanation:

area = (4 x 10) + (4 x 8) = 72 yd²

Answer:

2x+2y=-4

since we don't know the value of the letters, we could ignore it. then we add 2+2 which equals 4

6x-2y=12

In this case this equation is incorrect.

Step-by-step explanation:

sorry if I'm incorrect

(please if I'm correct, I really need the brainliest)

Answer:

(1,-3)

or

x=1 y= -3

Step-by-step explanation:

Looking at this we can see that there's a 2y in both of the equations (one is negative while the other is positive and so we'll add them)

so we have

(2x+2y)+(6x-2y)= -4+12

this simplifies to

8x=8

x=1

We know that x=1 and so we will plug this back into one of the two equations

2(1)+2y= -4

2+2y= -4

2y= -6

y= -3

Therefore the solution is (1,-3)

Step-by-step explanation:

[tex]area = length \times width \\ = (4x + 3) \times (2x + 2) \\ = ( {8x}^{2} + 8x + 6x + 6) \\ = ( {8x}^{2} + 14x + 6) \: {units}^{2} [/tex]

Answer:

[tex](8x + 14x + 6)^{2}[/tex]

Step-by-step explanation:

Area of a rectangle is length x breadth

In the given figure, the length is 2x + 2 and breadth is 4x + 3

So, the area would be:-

(2x + 2) (4x + 3)

[tex]8x^{2}[/tex] + 6x + 8x + 6

So the area would be => [tex](8x + 14x + 6)^{2}[/tex]

Answer:

Solution given:

f(x) = -3x + 1

f(-2)=-3×-2+1=7

f(0)=-3×0+1=1

f(3)=-3×-3+1=-8

So

Range is {7,1,-8) is a required answer

Answer:

-6F

Step-by-step explanation: It would be 5F(4hr) = 20F. So if you have 14F subtract 20F you get -6F. Hope this helped.

Answer:True

Step-by-step explanation: I did a quiz on it

Answer:

it is true am I right of this question

Answer:

Lin is between 150 and 160 cm

Step-by-step explanation:

The height is represented by the inequality :

h > 150 and h < 160

h > 150 - - (1)

h < 160 - - - (2)

Combining the two :

h > 150 means 150 is less than h but h is not upto 160

Thus, we have ;

150 < h < 160

This means height, h occurs between the range ; 150 cm and 160 cm

Answer:

Both Andre and Mai are correct

Step-by-step explanation:

A drawing of the the triangle ΔABC is created with MS Visio and attached here

In the drawing, we have;

Segment AB = x

Segment AC = 6

By trigonometric ratio, in a right triangle we have;

[tex]Tan(\angle X) = \dfrac{The \ length \ of \ the \ opposite \, side \ to \ \angle X }{The \ length \ of \ the \ adjacent\, side \ to \ \angle X}[/tex]

Where 'X' = 12° as shown in the figure, we have;

[tex]tan(12 ^{\circ}) = \dfrac{AB}{BC} = \dfrac{x}{6}[/tex]

Therefore, Andre is correct

Similarly, we have;

[tex]tan(78 ^{\circ}) = \dfrac{BC}{AB} = \dfrac{6}{x}[/tex]

Therefore, Mai is also correct

Therefore, Andre and Mai are correct.

Answer:

3x - (15 x 3) = 90

or

3x - 45 = 90

Explanation:

There are 3 boxes. We don't know how many are in them yet, so we write this as 3x. However, we know that we give away 15 to 3 different teachers. 15 x 3 = 45

Therefore, the first part is 3x - 45

We also know that in the end we have 90 left.

So our final equation is:

3x - 45 = 90

Answer: 2496in³

Step-by-step explanation:

To find volume, multiply the numbers by length, width, and height.

In this case, 24 is the length, 8 is the width, and 13 is the height.

24 × 8 × 13 = 2496 inches ³ (cubed).

Answer:

option C 2496

Step-by-step explanation:

you multiply 13 by 24 by 8

Answer:

Step-by-step explanation:

P = £1100

r = 5%

t = 6 years

I =P*r*t

[tex]I =1100*\frac{5}{100}*6\\\\I=11*5*6\\\\I = 330[/tex]

Amount = P + I = 1100 + 330 = £1430
