Answer:

1/10 and C

Step-by-step explanation:

     You wouldn't have a 9/10 because that is too high. It can't even possibly be 3/10. You have a 2/5 chance of getting one grape treat. Then, it would become 1/4 chance. That would make the chances of getting both very small. 1/10th is the only reasonable one.

     There is only 2 choices that it can land on. That means it would be half chance of getting either. Only 0.5 or C is 1/2 or 0.5 of half.

Salma made 6 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 6 necklaces was $35.40. If the beads cost $2.60 for each necklace, how much did each pendant cost?

Answers

Answer:

$3.30

Step-by-step explanation:

2.60*6= $15.60 beads per necklace

35.40-15.60= $19.80 total pendant

19.80/6= $3.30 per pendant

6(2.60) +p =$35.40
15.60 +p = $35.40
P=$19.80 but that is for all 6 pendant so must divide by 6
19.90 /6 =3.30
So each pendant is $3.30

A theater sold 85% of the tickets for a
play. If 170 tickets were sold, how many
tickets were originally put up for sale?

Answers

Answer:

200 tickets.

Step-by-step explanation:

85% = 85/100 = 0.85

170/0.85 = 200

= 200

Check:

200*0.85 = 170

Answer: hope this helps ♡

200 tickets were originally put up for sale.

Step-by-step explanation:

85% = 170

(we divide 85 and 170 by 85)

1% = 2

(now multiply 1 and 2 by 100)

100% = 200

(double check: 85% from 200 → (85×200) ÷ 100 = 170 ✓)

A box 2 m by 4 m by 8 m is filled with cubes of volume 8 cm³. If these
cubes were lined up, how long a line would that be?

Answers

The total line length of cubes lined up would be approximately 1.6 x 10^7 cm.

To find the total line length of cubes lined up, we need to find the total number of cubes in the box and then multiply it by the side length of a cube.

We can find the total number of cubes in the box by dividing the volume of the box by the volume of a cube:

Volume of the box = 2 m * 4 m * 8 m = 64 m³

Volume of a cube = 8 cm³ = 8 x 10^-6 m³ (converting the cm³ to m³)

Number of cubes = 64 m³ / 8 x 10^-6 m³ = 8 x 10^6

Then we can multiply the total number of cubes with the side length of a cube to find the total line length of cubes lined up :

Therefore, Line Length = 8 x 10^6 * 8 cm

= 6.4 x 10^7 cm

= 1.6 x 10^7 cm.

Step-by-step explanation:

2/5 + 1/6 = 17/30

Make them easier to add by making them have the same denominator.

2/5 = 12/30

1/6 = 5/30

12/30 + 5/30 = 17/30

Answer:

17/30

Step-by-step explanation:

First, we need to get the lowest common denominator, which is 30 (5 times 6 and 6 times 5) since we multiplied the denominators we have to multiply the numerators by the same numbers (6 and 5) now we get 12/30 + 5/30, which equals 17/30

Which graph represents the linear equation y equals one fourth x plus 1 on the coordinate plane?

Answers

Answer: It is the last graph you listed. y=1/4x+1 this means the slope is 1/4 and the y intercept is. The last graph matches this exact description.

Step-by-step explanation:

I believe it’s the second before last graph because the plus one in the equation represents a shift up of one unit which is represented and being that the slope (rise/run) is 1/4, it also shows how you reach the next point by running 4 units to the right and rising one unit up.

The equation of line shown in figure is,

⇒ y = x - 4

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (4, 0) and (0, -4).

Now,

Since, The equation of line passes through the points (4, 0) and (0, -4).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (- 4 - 0) / (0 - 4)

m = - 4 / -4

m = 1

Thus, The equation of line with slope 1 is,

⇒ y - 0 = 1 (x - 4)

⇒ y = x - 4

Therefore, The equation of line is,

⇒ y = x - 4
