where r is the rate

i is the interest

p is the principal

t is the years

STEP 2: substitute the given values

For #2, it would be the first one

Like terms are the ones that have the SAME variable with SAME exponent. So the ones with x will be considered like terms. The ones with a will also be like terms.

For #1, you would use this fact to combine the like terms. For instance, 3a and -2a are like terms so when they are combined you are left with 1a

The Income-tax Sasha has to pay is $2334

The part of income a person pays to the government as a contribution to the growth of the nation is called Income Tax.

Sasha  earns $16 per hour

Total hours she worked is 2000

Total annual income is $16 *2000 = $32000

Deductions = $12550

Net Salary = $32000 - $12550

Salary on which tax has to be paid = $19450

According to the federal law, Tax table 2021

For income in the range of $9,951 to $40,525 the tax will be 12%

12% of $19450 has to be paid

=(12/100) * 19450

=$2334

Therefore, the Income tax Sasha has to pay is $2334

Erica tiene 85 libros y 9 estanterias, para colocar todos los libros sin que le sobre ninguno, puede colocar 17 libros en 5 estanterias.

Primero sabemos que Erica tiene, al menos, 50 libros, entonces si definimos L como el numero de libros que tiene, tendremos:

L ≥ 50.

Si coloca 11 en cada estanteria, le sobran 8, entonces podemos escribir:

L = n*11 + 8   (donde n es un número entero).

Si coloca 9, le sobran 4, entonces:

L = k*9 + 4 (donde k es un número entero).

Entonces tenemos que:

n*11 + 8 =  k*9 + 4

n*11 - k*9 + 8 - 4 = 0

n*11 - k*9 + 4 = 0

n = (k*9 - 4)/11

Lo que podemos hacer es evaluar k en distintos valors enteros de tal forma que la solucion de n tambien sea entera. Por ejemplo, si k = 2 tendremos:

n =  (2*9 - 4)/11 = 14/11

Notar que en este caso n no es entero, asi que no sirve.

Seguimos, si k = 9 tendremos:

n = (9*9 - 4)/11 = 77/11 = 7

Ambos son enteros.

Entonces Erica tiene:

L = 9*9 + 4 = 85 libros en total.

Y el numero de estanterias sera el maximo entre n y k, que es k = 9, hay 9 estanterias.

Para colocarlos sin que le sobren, puede colocar 17 libros en cada estanteria. Asi con 5 estanterias colocara los 85 libros.

Answer: the large jar is cheaper

Step-by-step explanation:

If you divide the £1.54 by 440g and £1.26 by 340g, you'll find which one is cheaper per gram :

1.54/440 = 0.0035

1.26/340 = 0.0037

So, by comparing both prices/gram, you've found that the large jar is cheaper.

Answer:

The total volume of water in the pool  =-2 (x-11)(x+5) ft^3

Step-by-step explanation:

a) (2x^2 + 12x + 10) - (4x^2-100)

= 2x^2+12x+10-4x^2+100

= -2x^2+12x+110

b)

Lets simplify first by taking the GCF out:

= -2 (x^2-6x-55)

Now Just simplify by finding the product of a and c

I used -11 and 5 because when you multiply -11x5 you get -55, and when you do -11+5 you get -6.

= -2 (x-11)(x+5) ft^3

Answer:

Step-by-step explanation:

Hi ok heres how I got it:

If the equation is y=3x+2, we just need to plug in each x and y value and see which one doesn't work. Either that, or we can just locate it on the graph.

For example,

10,32

Plugging it in gives us:

32=3(10)+2.

This is correct, meaning that A is NOT the answer.

Continuing testing, and we will find that B is the incorrect pair.

13=3(8)+2 is NOT correct.

13=24 is not equal.

Also,

-13=3(-5)+2 CORRECT,

-22=3(-8)+2 CORRECT AS WELL

Answer:

The ordered pair does not lie on the graph of this function is B. (8, 13)

Step-by-step explanation:

=> y = 3x + 2...i)

By putting the value of x in equation i).. from the options

firstly, putting the value of x = 10

=> y = 3(10)+2

=> y = 32

so, its the ordered pair that lie on the graph

now , putting the value of x= 8

=> y = 3(8) +2

=> y = 24 +2

=> y = 26

its 26, so the ordered pair does not lie on the graph of this function is B. (8, 13)

Answer:

The volume of the prism is 243 cm³

Step-by-step explanation:

The volume of the prism is V = B × H, where

∵ The prism is a triangular prism

∴ Its base is a triangle

∵ The base of it is a right triangle

∴ Its area B = [tex]\frac{1}{2}[/tex] b h, where b and h are the legs of the right angle

→ We have one leg of the right angle and the hypotenuse, so we

   must use the Pythagoras Theorem to find the other leg

∵ (5.4)² + h² = (7.8)²

∴ 29.16 + h² = 60.84

→ subtract 29.16 from oth sides

∴ h² = 31.68

→ Take √  for both sides

∴ h = 5.6284989 cm

→ Now find the area of the base

∵ B = [tex]\frac{1}{2}[/tex] (5.4)(5.6284989)

∴ B = 15.196947 cm²

→ Let us use the rule of the volume above

∵ V = B × H

∵ H = 16 cm

∴ V = 15.196947 × 16

∴ V = 243.151153 cm³

→ Round it to 3 significant figures

∴ V = 243 cm³

∴ The volume of the prism is 243 cm³
