Answer:

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - 2 , then

y = - 2x + c ← is the partial equation

to find c substitute (3, - 2 ) into the partial equation

- 2 = - 6 + c ⇒ c = - 2 + 6 = 4

y = - 2x + 4 ← equation of line in slope- intercept form

What is the absolute value of Point B labelled on the number line? A number line with point A at coordinate negative 2.2, point

bulgar [2K]

Answer:

The absolute value of point B on the number line is 2.2.

Step-by-step explanation:

A number line is given with point A at coordinate negative 2.2, point B at coordinate negative 1.6, and point C at coordinate 1.2.

So, on the number line, all the points having negative value are on the left side of zero.

Position of the point A is -2.2,

Position of the point B is -1.6,

Position of the point C is -1.2.

The absolute value of any point on the number line is the distance of that point from zero.

So, the absolute value of point B on the number line is the distance of point B from zero which is |-2,2|=2.2.

How many plastic cubes can fit into the box?

netineya [11]

Option D:

160 plastic cubes can fit into the box.

Solution:

Convert mixed fraction into improper fraction.

Length of the box = 4 ft

Width of the box = $2\frac{1}{2}=\frac{5}{2}$ ft

Height of the box = 2 ft

Volume of the box = length × width × height

$$=4\times\frac{5}{2} \times2$

= 20 ft³

Volume of the box = 20 ft³

Length of the plastic cube = $\frac{1}{2}$ ft

Volume of the cube = length × length × length

$$=\frac{1}{2} \times\frac{1}{2} \times\frac{1}{2}$

$$=\frac{1}{8} \ \text{ft}^3$

Volume of the cube = 0.125 ft³

$$\text{Number of plastic cubes}=\frac{\text{Volume of box}}{\text{Volume of cube}}$

$$=\frac{20}{0.125}$

= 160

Number of plastic cubes = 160

Hence 160 plastic cubes can fit into the box.

Option D is the correct answer.

Kamala gave rs 1,50,000 to her friend.She gave currency notes of denomination Rs. 50,Rs.100,Rs.500 in the ratio 4:3:5.How many n

vivado [14]

Answer

Find out the how many notes of each denomination did she give .

To prove

Let us assume that x be the scalar multiplication of the Rs 50, Rs100,Rs500 curreny notes.

As given

Kamala gave Rs 1,50,000 to her friend.

She gave currency notes of denomination Rs. 50,Rs.100,Rs.500 in the ratio 4:3:5.

Rs50 currency note gave in the denomination = 4x

Rs100 currency note gave in the denomination = 3x

Rs500 currency note gave in the denomination = 5x

than the equation becomes

4x + 3x + 5x = 150000

12x = 150000

$x = \frac{150000}{12}$

x = 12500

Thus

Rs50 currency note gave in the denomination = 4 × 12500

= 50000

Rs100 currency note gave in the denomination = 3 × 12500

= 37500

Rs500 currency note gave in the denomination = 5 × 12500

= 62500

Jane little rents a car for 39.00 a week. She pays 15.00 a week for the insurance and spends 17.50 weekly on gas. What will her

Montano1993 [528]

There are 4 weeks in a month.
All the numbers in the question are saying how much she will pay per week,so all we have to do is multiply each number by 4.
39.00×4=156
15.00×4=60
17.50×4=70
Now all we have to do is add.
156+60+70=286.

Your answer will be that Jane has to pay 286 dollars per month on the car.
