Answer:

The dividend is 3935.

Step-by-step explanation:

Division:

Suppose we have a division of a by b.

a is the dividend, b is the divisor. The result is the quotient, that i will call q, and the rest is given by r.

They are related the following way:

a = q*b + r

That is, the divident is the multiplication of the divisor and the quotient, added by the rest.

The partial quotients are 20 and 4.

This means that the quotient is q = 20*4 = 80.

A division problem has 49 as its divisor. The remainder is 15. What is the dividend?

So b = 49, r = 15. Then

a = q*b + r = 49*80 + 15 = 3935

The dividend is 3935.

Jackie bougth red and green binders and paid $2.25 for each red binder and $3.24 for each green binder and spent a total of $21.

Alenkasestr [34]

Answer:

4 each of red and green binders.

Step-by-step explanation:

Given: Price of each red binder is $2.25.

Price of each green binder is $3.24.

Total Jackie paid is $21.96.

Lets assume the number of red binder bought be "x".

∴ Total amount paid for red binder= $number\ of\ red\ binder \times price\ for\ each\ red\ binder$

⇒ Total amount paid for red binder= $x\times \$ 2.25= \$ 2.25x$

Now, finding the amount paid for green binder.

As we know the total amount paid by Jackie is $21.96 and she bought same number for each binder.

Jackie paid for x number of green binder= $\$ 3.24\times x= \$ 3.24x$

Next, we can write an equation on total amount paid for Green binder to find value of x.

∴ $\$ 21.96-\$ 2.25x= \$ 3.24x$

Solving the equation.

$\$ 21.96-\$ 2.25x= \$ 3.24x$

Adding both side by \$ 2.25x

⇒ $\$ 21.96= \$ 3.24x+\$ 2.25x$

⇒ $\$ 5.49x = \$ 21.96$

cross multiplying both side.

⇒ $x= \frac{21.96}{5.49} = 4$

∴ x= 4

Hence, Jackie bought 4 each of red and green binders as she bought same number of each binders.

Andrea needs 4 kilograms of oranges. The scale below shows the weight of the oranges she has in her kitchen. Part A. About how m

juin [17]

We know that

<span>each space on the balance represents
1 kg/ 10 spaces----------> 0.10 kg
in the picture there are 14 spaces
so
14*0.1-------> 1.4 Kg
</span>
Part A) About how many kilograms of oranges does Andrea have? Round your answer to the nearest kilogram

Andrea has 1.4 kg of oranges------> to the nearest kilogram-----> 1 Kg

the answer is
1 kg

Part B) About how many more kilograms of oranges does Andrea need?
Andrea needs=(4 Kg-1.4 Kg)------> 2.6 Kg

the answer part B) is
2.6 Kg

What is an equation of the line that passes through the points (3,-8) and (1, -2)? Put your answer in fully reduced form.

Kazeer [188]

Answer:

Step-by-step explanation:

Find what relationship x and y have. In this case, y is x multiplied by -3, plus 1.

(3,-8) The number 3 is x and -8 is y. Use the rule above to see if it's correct. Like so: -8 = 3 ( - 3) + 1

-8 = -9 + 1

-8 = -8

The rule/equation is correct.

Find the value of y

Olin [163]

Answer:

y ≈ 4.3 cm

Step-by-step explanation:

Given 2 secants from an external point to the circle.

The the product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is

3(3 + y) = 2(2 + 6 + 3) = 2(11) = 22, that is

9 + 3y = 22 ( subtract 9 from both parts )

3y = 13 ( divide both sides by 3 )

y ≈ 4. 3 cm ( to the nearest tenth )
