Answer:

4,300

Step-by-step explanation:

Lateral area of a squared Pyramid is given as ½ × Perimeter of base (P) × slant height of pyramid

Thus, we are given,

Side base length (s) = 43 yd

height (h) = 25 yd

Let's find the perimeter

Permimeter = 4(s) = 4(43) = 172 yd

Calculate the slant height using Pythagorean theorem.

Thus, l² = s²+h²

l² = 43²+25² = 1,849+625

l² = 2,474

l = √2,474

l ≈ 50 yd

=>Lateral area = ½ × 172 × 50

= 172 × 25

= 4,300 yd

Christine must buy at least 45 fluid ounces of milk at the store. The store only sells milk in 200 milliliter bottles. If there

ratelena [41]

Since there are 1000 milliliters in a liter, that means that there are 33.8/1000 fluid ouncers per milliliter. That means that each 200 mil bottle is 6.76 fluid ounces or 33.8/1000*200. 45/6.76 = 6.66 but you have to round up to a whole number of bottles since you can buy 2/3 of a bottle which makes your answer 7 bottles.

Sarawong is carrying six pages of math homework and four pages of english homework. a gust of wind blows the pages out of his ha

Eduardwww [97]

The sample space of the experiment (i.e. the total number of ways he can pick 7 random pages out of a total of 6 + 4 = 10 pages) is given by:

$^{10}C_7=120$

If he picks at least 5 pages of maths homework, this means that he either picked 5 pages or 6 pages of maths homework.

The number of ways he can pick 5 or 6 maths homework is given by:

$^6C_5+{ ^6C_6}=6\times1=6$

Therefore, the probability that he recovers at least 5 pages of his math homework is given by:

$\frac{6}{120} = \frac{1}{20}$
