Bad White [126]2 years ago
5 0

Answer:

the answer is 60

Step-by-step explanation:

so you see that there's 20 percent right, you find what number u can add it by to get 100, so 80+20=100 so u do that and put it in a decimal form which is 0.8 and you multiply it by the price so 0.8 x 75= 60

Harper has $15.00 to spend at the grocery store. She is going to buy bags of fruit that cost $4.75 each and one box of crackers
Anestetic [448]

Answer:

Step-by-step explanation:

Let x represent the maximum number of bags of fruit that Harper can buy.

She is going to buy bags of fruit that cost $4.75 each and one box of crackers that cost $3.50. This means that the total cost of x bags of fruit and one box of crackers would be

4.75x + 3.5

If Harper has $15.00 to spend at the grocery store, it means that

4.75x + 3.5 = 15

4.75x = 15 - 3.5 = 11.5

x = 11.5/4.75

x = 2.42

Therefore, the maximum number of bags of fruit that Harper can buy is 2 because the number of bags must be whole numbers.

Factor completely.x2 + 3xy - 4y2 - 5y + 5x
nikitadnepr [17]

Answer: We have to factor the polynomial completely, the polynomial is:

x^2+3xy-4y^2-5y+5x

The factorized answer is:

\begin{gathered} x^2+3xy-4y^2-5y+5x\rightarrow(1) \\  \\  \\ \text{ Rewriting \lparen1\rparen gives:} \\  \\  \\ x^2-xy+4yx-4y^2+5x-5y \\  \\ \text{ Factoring out the common factors gives:} \\  \\ x(x-y)+4y(x-y)+5(x-y) \\  \\ \text{ The last step is to factor out the }(x-y): \\  \\ (x-y)(x+4y+5)\Rightarrow(2) \end{gathered}

The final answer is option(d) because (2) matches this option.

Hallar el menor número no divisible por 4, 6, 9, 11 y 12, tal que al dividirlo por estos números se obtengan restos iguales.
Aloiza [94]

Answer:

397

Step-by-step explanation:

Sea 'p (x)' el número que no es divisible por 4, 6, 9, 11 y 12 de manera que cuando se divide por estos números da un resto igual, tenemos;

Por teorema del resto, tenemos;

p (x) = (x - a) · Q (x) + R

Dónde;

p (x) = El número, que se divide

Q (x) = El cociente

(x - a) = El divisor

R = El resto

Dado que el número más pequeño es 4, el resto, 0 <R <4

Para el número entero más pequeño arriba (x - a) · Q (x), tenemos;

R = 1

Observamos que el mínimo común múltiplo de 4, 6, 9, 11 y 12 = 396, por lo tanto, podemos tener;

(x - a) · Q (x) = 396

R = 1, dar;

p (x) = 396 + 1 = 397

Por lo tanto;

El número que no es divisible por 4, 6, 9, 11 y 12, de manera que cuando se divide por estos números da residuos iguales, p (x) = 397

Juli buys a flat with 48 flowers. She was wants to plant them in equal rows of 5 flowers. How many rows can Juli plant? How many
miss Akunina [59]

Answer:

5 row, 3 left

Step-by-step explanation:

She has 48 flowers, 5 flowers one row

How many rows can she make? So divide

48/ 5

= 9.6

So she can only make 9 rows

The leftovers flowers are the flowers that didn't manage to make 5 per row

Therefore, if she can make 9 rows, in other words 9 x 5 = 45

45 flowers were able to be placed in a sequence of 5 per row

So the ones that are left is

48 - 45

= 3
