pizza palace cuts a medium pizza into 8 slices.the same size pizza at pizza pioneers si cut into 16 slices.Jasmine ate 4 slices of a medium pizza from pizza pioneers.what fraction of the pizza from pizza palace is equal to 4/16. Explain

Answers

Answer:

$(1)/(4)$

Step-by-step explanation:

Given,

Pizza palace cuts a medium pizza into 8 slices,

So, the part of each slice in Pizza palace = $(1)/(8)$

Let x be the number of slice eaten from Pizza palace,

Such that it is equal to $(4)/(16)$ part of the pizza,

$(1)/(8)* x = (4)/(16)$

$(x)/(8)=(4)/(16)$

$16x = 32$

$\implies x = 2$

Hence, $(1)/(4)$ of the pizza from pizza palace is equal to 4/16.

It would be half of the pizza from Pizza Pioneers because 16 is 8 doubled. Therefore, two pieces of pizza from Pizza Palace is equal to 4 pieces from Pizza Pioneers.

Answer:

∠3 = 62°

Step-by-step explanation:

The diagonals of a kite are at right angles to each other, hence

Triangle containing ∠ 3 is a right triangle

The sum of the 3 angles in a triangle = 180°, thus

90 + 28 +∠3 = 180

118 + ∠3 = 180 ( subtract 118 from both sides )

∠3 = 62°

5 college students were asked how many hours of sleep did they get at night on the average the responses were a 7 hours 9 hours 5 hours 6 hours and 8 hours what is the average amount of hours of sleep do college students got in a night

Answers

7 Hours on Average

add up all the hours and you get 35

then divide 35 by the number of given hours which is 5

35/5 = 7

so the average amount of hours slept was 7

Answer:

7 hours

Step-by-step explanation:

To find this average, add up the five data points given and divide your result by five (5):

(7 + 9 + 5 + 6 + 8) / 5 = 35 / 5 = 7

This group of students averaged 7 hours of sleep per night.

The circumference of the earth is approximately 131,000,000ft write this number in scientific notation and tell how you knew to use a positive or a negative exponent

Answers

U use a negative exponent to write a number smaller than 1, positive exponents are used to write numbers bigger than 1. clearly 131,000,000 is bigger than 1 so we use a postive exponent. there's always a decimal at the end of a whole number. and we move that decimal to the front where the fron value is more thnand one but less than 10. we move the decimal 8 places to the left and u get to 1.31X10^8
1.31 times 10 to the 8th power.
