I NEED HELP ASAP THIS IS DUE IN 10 MIN HELP MEE

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:

Alternate exterior angles

Answer: #444

Step-by-step explanation:

First find the original selling price of the article.

When sold for #372 the profit was 24%. Assume the original price is x.

372 = x + 24% * x

372 = 1.24x

x = 372 / 1.24

= #300

If he wanted to make a profit of 48% he should have sold for:

= Original price + (original price * 48%)

= 300 + (300 * 48%)

= #444

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:

  Any of {412, 523, 634, 745, 856, 967, 1078, 1189}

Step-by-step explanation:

Relations are given between the number of 10-clip boxes, the number of 100-clip boxes, and the number left over. We assume there are at least one of each size box, and that there are fewer than 10 clips left over. (10 could be put into another box.)

__

Let h represent the number of 100-clip boxes. Then h-3 is the number of 10-clip boxes, and h-2 is the number of clips left over. The total number of paperclips is ...

  10(h -3) +100h +(h -2) = 111h -32

In addition, we require ...

  h -3 > 0 and h-2 < 10

  3 < h < 12 . . . . . . . rearranging these inequalities

So, Brian could have 111h -32 paper clips, where 3 < h < 12. That could be any of {412, 523, 634, 745, 856, 967, 1078, 1189} paper clips.

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

hope it helps  

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:

Good luck!

Step-by-step explanation:

8. -3.2

X= -9+14 = 5

Y= 0-16 = -16

-16/5 = -3.2

9. 1.5

X= 13-2 = 11

Y= -1+18= 17

17/11= 1.5

Answer:

75 sweets

Step-by-step explanation:

Given that

There is 120 sweets that are put into three different size boxis

And, the ratio of small box to medium box to large box is 1:2:5

We need to find out the no of sweets in the large box

So,

The number of sweets in a large box is

= 120 sweets × 5 ÷ (1 + 2 + 5)

= 120 sweets × 5 ÷ 8

= 75 sweets

Answer:

where does the name come from?

Step-by-step explanation:

Answer:

x = 29.69

Step-by-step explanation:

Since the Adjacent side of the given angle 38, is given, and opposite needs to be found out, we will us the Tangent ratio:

Tan(38) = [tex]\frac{x}{38}[/tex]

=> To isolate x all by itself, multiply 38 from the right side of "=", on both sides;

Tan(38) * 38 = x

29.69 = x

Hope this helps!

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:

I think the answer is intersecting but not perpendicular

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:

D)  1:2

Step-by-step explanation:

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: 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:

The answer is "0.975"

Step-by-step explanation:

Please find the complete question in the attched  file.

Find the remaining distance inside the original map

[tex]\to \frac{9}{6}=1.5 \ in[/tex]

Dividing the value by 6 because there are 7 rest stop:

[tex]\to \frac{2 \ inches}{39 \ inches} =\frac{1.5 \ inches}{x \ miles}\\\\\to x=39 \times \frac{1.5}{2}\\\\\to x=29.25 \ miles[/tex]

Finding the diatance of the rest stop in the new map

Using proportion:

[tex]\to \frac{1 \ inches}{30 \ miles} =\frac{x \ inches}{ 29.25 \ miles}\\\\\to x= \frac{29.25}{30}\\\\\to x=0.975 \ in[/tex]

Answer:

a = -7

Step-by-step explanation:

a - 5 = -12

  +5     +5

a = -7

Answer:

a = -7

Step-by-step explanation:

First, we have to make both sides equal. We do this by isolating the variable a. When we add 5 to -12, it becomes -7.

Answer:

67%

Step-by-step explanation:

Let the percentage of the first solution = x

7 gallons + 4 gallons = 11 gallons

Our system of equation is

Seven gallons of a sugar solution was mixed with 4 gallons of a 80 percent sugar solution to make an 72 percent sugar solution.

7 gallons × x % + 4 gallons × 80% = 72% × 11 gallons

= 7x + 3.2 = 7.92

Collect like terms

7x = 7.92 - 3.2

7x = 4.72

x = 4.72/7

x = 0.6742857143

Converting to percentage

0.6742857143 × 100

= 67.42857143%

Approximately, the percent concentration of the first solution is 67%
