Answer:

[See Below]

Step-by-step explanation:

✦ In this figure there are two shapes; A triangle and a square. So you'll need to know the area formula for both:

✧ Square ∼ s² (Side Squared)

✧ Triangle ∼ ½ × b × h

✦ So now just solve for each area:

✧ Square ∼ 15² = 225

✧ Triangle ∼ ½ × 15 × 3 = 22.5

✦ Now add each area together to get the total area:

✧ 225 + 22.5 = 247.5

Radius: r = d/2
Surface Area of a Sphere: SA = 4πr²

Step-by-step explanation:

Step 1: Define

d = 19 cm

Step 2: Find SA

Substitute [R]: r = 19 cm/2
Divide: r = 9.5 cm
Substitute [SAS]: SA = 4π(9.5 cm)²
Exponents: SA = 4π(90.25 cm²)
Multiply: SA = 361π cm²
Multiply: SA = 1134.11 cm²
Round: SA ≈ 1134 cm²

HELPPPPPP ASAP What is the length of the third side of the window frame below? (5 points) (Figure is not drawn to scale.) 58a 1)

ollegr [7]

Answer:

The answer is 3) 40.

Step-by-step explanation:

since you're working with the Pythagorean theorem, you should know that a^2+b^2=c^2, therefore, we know that we only have two sides. we have a and c. we know that a = 42 and c = 58, giving us the equation of 42^2+b^2=58^2,

we want to find b!

so we would simply subtract the two.

58^2 - 42^2 = b

b = 1600

now we want to square root,

b = sqrt1600

which in the end, gives us the answer of 40.

Can anyone explain the basics of solving systems to linear equations?

Len [333]

Answer:

A system of linear equations is just a set of two or more linear equations. In two variables (x and y) , the graph of a system of two equations is a pair of lines in the plane. ... The lines intersect at infinitely many points.
