9. a) In a school of 800 students, 5/8 are boys and rest girls.

1) Find the number of boys and girls.
2) Find the percentage of boys and girls.​

Answer:

-46

Step-by-step explanation:

2x+43=2x-3

We simplify the equation to the form, which is simple to understand

2x+43=2x-3

We move all terms containing x to the left and all other terms to the right.

+2x-2x=-3-43

We simplify left and right side of the equation.

0x=-46

0=-46

The left and right sides are not equal, therefore there is no solution. This equation is invalid.

Answer:

k>8

Step-by-step explanation:

k more than 8 indicates that the value of k is larger than 8. So the inequality sign opens towards k and closes towards 8.

Hope this helps!

Answer:

There are 14,512 people in the town in 2005.

Step-by-step explanation:

Answer:

7 and 12

Step-by-step explanation:

x - y = 5

y = (5+x)

x+ (5+x) = 19

2x +5 = 19

2x = 14

x = 7

           19-7 = 12

12 +7  = 19

12-7 = 5

Answer:

x----------> the length of the room

y----------> the width of the room

we know that

x*y=120---------> equation 1

y=(5/6)x--------> equation 2

substitute 2 in 1

x*[(5/6)x]=120------> (5/6)x²=120-----> x²=120*6/5-----> x²=144

x=12 ft

y=(5/6)*12-----> y=10 ft

the answer is

the dimensions of Winnie's bedroom are

the length of the room is 12 ft

the width  of the room is 10 ft

Answer:

3 1/4

Step-by-step explanation:

total kg of apples and oranges in the store =

[tex]4\frac{1}{10} + 6\frac{3}{4}[/tex]

[tex]10\frac{4+30}{40}[/tex]

[tex]10\frac{34}{40}[/tex]

kg left after the sales

[tex]10\frac{34}{40} - 7\frac{3}{5}[/tex]

[tex]3\frac{34 - 24}{40}[/tex] = [tex]3\frac{10}{40}[/tex]

To transform to the simplest form. divide both the numerator and the denominator by 4

3 1/4

Answer:

31.2 inches

Step-by-step explanation:

Draw a line representing the height of the triangle, and divide it into 2 triangles.

Apply Pythagoras Theorem on one of the smaller triangles first.

[tex]h = \sqrt{ {36}^{2} - {(36 \div 2)}^{2} } \\ h = \sqrt{ {36}^{2} - {18}^{2} } \\ h = \sqrt{972} \\ h = 31.17691...[/tex]

h = 31.2 inches (rounded to the nearest tenth)

delta math

Answer:

Step-by-step explanation:

Touching angles have to equal  the full amount of degrees. This means oppisite angles are the same so 7/6, 5/8, 1/4, 2/3. This then means that 1/4 and 5/8 are the same. 3 and 5 would add up to the full amount of a flat line. 2 and 7 could as well, but diffrently (i dont remebr the terms lol). 6/8 would be supplementary, but wouldnt show that the lines are parrlele. Nether would D, as it is true but not helpful.  B seems the most likely at this point with a being a close second. I am so sorry I couldnt be more helpful

Answer:

Wooden Embellishments Ceramic Embellishments Metal Embellishments

2 hearts 2 cats 3 stars

3 clouds 3 dogs 5 squares

4 birds

A.1/27

B. 3/40

C. 1/9

D.3/8

Answer:

ENGLISH

One of the angles must equal 90 degrees and the other two angles must add up to 90 degrees.

Uno de los ángulos debe ser igual a 90 grados y los otros dos ángulos deben sumar 90 grados.

Answer:

N

Step-by-step explanation:

Since C is 48 you minus 6 from it since 6 is on the side so thus 48 - 6 = 42

Happy I can help

Answer:

48

Step-by-step explanation:

We are going to use trigonometry to solve for the wanted angle

Remember these are the trigonometric functions

( Remember SOH CAH TOA )

Sine = Opposite over Hypotenuse (SOH)

Cosine = Adjacent over Hypotenuse (CAH)

Tangent = Opposite over Adjacent (TOA)

For angle Ф

we are given its adjacent side length (6) and the hypotenuse (9)

Adjacent and hypotenuse corresponds with the trig function Cosine

So we will use cosine to solve for the missing angle

( let x = missing angle )

( remember cosine = adjacent over hypotenuse )

[tex]cosX=\frac{6}{9} \\\frac{6}{9} =.66\\cos(x)=.66[/tex]

now we want to get rid of the "cos" on the x

To do so we take the inverse of cos ( arc cos ^-!1 ) and apply it to each side

so...

[tex]arcos(cos(x))=x\\arccos(.66)=48.1[/tex]

we're left with x = 48.1

Answer:

$1,800

Step-by-step explanation:

Given

Total revenue last year = $2,800

If they spent 1/4 of their revenues on marketing;

Amount spent on marketing = 1/4 * 2800

Amount spent on marketing = $700

Remaining money = 2800 - 700

Remaining money = $2100

If 1/7 of the remaining money is spent on upgrading their facilities, then;

Amount spent on upgrading facilities = 1/7 * 2100

Amount spent on upgrading facilities = $300

Total amount spent on marketing and facilities  = $700 + $300

Total amount spent on marketing and facilities  = $1000

Amount left = $2,800 - $1,000

Amount left = $1,800

Answer:

Step-by-step explanation:

1) take a better picture next time

2) Add 70+90= 160 then 180-160= 20 to find the last angle

3) tan20= x/20

4) x= 7.27
