Step-by-step explanation:

A=⎣⎢⎢⎡324−21−33−12⎦⎥⎥⎤,x=⎣⎢⎢⎡xyz⎦⎥⎥⎤,B=⎣⎢⎢⎡814⎦⎥⎥⎤

∣A∣=⎣⎢⎢⎡324−21−33−12⎦⎥⎥⎤

=3[1−3−12]−1(−2)[24−12]+3[241−3]⇒3(2−3)−2(4+4)+

The surface area of a square pyramid is 125 square feet. The base length is 5 feet. What is the slant height?
Mademuasel [1]

Answer:

10.31 ft

Step-by-step explanation:

the base is 25 ft²

leaves 100 ft² for the 4 sides on top

so each triangle got 25ft²

the base length of the triangle is 5ft, bc it's the base length of the pyramid

so the height of the triangle is 10ft,

bc only then do we get a surface area of 25ft²

(b * h /2) for the triangle

now that we got base length and height,

let's look for the slant

we recall the pythagoras stuff to get the missing side of the triangle. but notice that we need to split the triangle in half to get a 90° angle.

leaving us with 10ft (height) and 2.5ft

slant² = 10² + 2.5²

slant² = 106.25

slant = sqrt(106.25)

slant = 10.31

Gerber Product's Gerber Mixed Cereal for Baby contains, in each serving, 60 calories and 11 grams of carbohydrates†. Gerber Mang
yulyashka [42]

Answer:

Gerber mixed cereal for baby 1 servings and Gerber mango tropical fruit dessert 2 servings

Step-by-step explanation:

calories = 60 + 80 + 80 = 220

grams of carbohydrates = 11 + 21 +21 = 53

this is probably easy to guess, but the way to do it it's the following

first see the units you need, for example in 53g

to get that 3 with the numbers you have to sum ( 21, 11) you need to sum 3, 13, etc, numbers (because you only have ones)

then you look at the tens in 53, and you finish to figure out that you can only sum 3 numbers, and that, to get that 5, they need to be two 21 and one 11.

that means the only way to get that amount of carbs is with 1 serving of Gerber mixed cereal for babyand and 2 servings of Gerber mango tropical fruit dessert.

Then you need to check that the amount of calories in that servings it's the required too. 60 + 80 + 80 = 220
