How do I solve this?

Mathematics
1 answer:
snow_tiger [21]2 years ago
8 0

Answer:

B

Step-by-step explanation:

it means we assume that the progression between 2 interval points is linear (a straight line from the begin of the interval to the end of the interval).

so, a length of 9.5 in falls into the interval [9, 11].

in this interval we see that the change rate is (21 - 11)/(11 - 9) = 10/2 = 5/1

that means for every inch longer we expect 5 oz more.

the line equation there is

y = 5x + b

11 = 5×9 + b

11 = 45 + b

-34 = b

so, the line is

y = 5x - 34

for x = 9.5

y = 5×9.5 - 34 = 47.5 - 34 = 13.5 oz

B is with 13.4 the closest right answer.

Answer:

a) 2.5 pounds of candy

b) 2.5 pounds of candy

    \frac{0.5}{1} :\frac{y}{5}

    y × 1 = 0.5 × 5

    y = 2.5

Step-by-step explanation:

1 = 5

1/2 = y or 0.5 = y

\frac{0.5}{1} :\frac{y}{5}

y × 1 = 0.5 × 5

y = 2.5

Select the representation that does not change the location of the given point. (4, 110°)
miss Akunina [59]

Answer:

(4,470°)

Step-by-step explanation:

The representation that does not change the location of (4, 110°) in polar coordinates are all points that are coterminal with the given point.

The only point among the given options that is coterminal with (4, 110°) is (4, 470)°

The two points have the same magnitude and 470°-360°=110°.

Since 110° is coterminal with 470° and the two points have the same magnitude with the same sign, the two points represent the same location in polar coordinates.

The correct choice is (4,470°)

Crazy boy [7]

Answer:

The teacher can hand out pizza to 8 students.

Step-by-step explanation:

To find how many slices of pizza the teacher can hand out , you can divide 7 by 7/8 and round down the nearest whole number.

7 ÷ 7/8 = 8

8 is already a whole number. No need to round down.

The teacher can hand out pizza to 8 students.
