Slope = -4.000/2.000 = -2.000

x-intercept = 0/2 = 0.00000

y-intercept = 0/1 = 0.00000

Kayla’s work to find the surface area of a composite solid formed when a rectangular prism and rectangular pyramid are joined at

docker41 [41]

Answer:

Option B

Step-by-step explanation:

The reason is because the surface area is not including the base of the pyramid and the top of the prism.

Option b. she left out one of the faces of the solid she should have simplified 2((5)(7))+2((6)(7))+2[1/2(5)(9.3)]+2[1/2(6)(9.2)]+(5)(6)

Step-by-step explanation:

we know that

The surface area of the composite figure is equal to the surface area of the pyramid not including the base plus the surface area of the prism not including the top

SA= 285.7 units squared

Can I please get help with this ? Thank you

Answer:

$2.25268983 * 10^{103}$

Step-by-step explanation:

The upside down exclamation point(¡) denotes the subfactorial in math. There are two ways to approach solving the subfactorial, one being exact, while the other is a more practical approach.

One way (the mathematically correct way) is using the formula:

n=n!∑[(-1)^k]/k!, where k starts at 0 and counts to n.

However, another, less accurate way is simply ¡n = [n!/e], where the brackets mean to round to the nearest integer, which returns 2.25268983 * 10^(103)

Hope it helps :) and let me know if you want me to elaborate, or if the notation used was intended to be something else, as the subfactorial of 72 seems like an unnecessary amount of tedium.

The area of a rectangle is pool is (15x-9) square units. Factor 15x-9 to find possible dimensions of the pool

Darya [45]

This is the concept of algebra, given that the area of a rectangular pool is (15x-9), the possible dimensions of the pool by factoring will be:
Area=length×width
Area=(15x-9)
factoring the above we get:
Area=3(5x-3)
therefore the possible dimension will be:
length=5x units
width=3 units

5. Determine the length of side y to the nearest hundredth.

KonstantinChe [14]

Answer:

64.50 cm

Step-by-step explanation:

$\sin \: 51 \degree = \frac{y}{83} \\ \\ 0.7771459615 = \frac{y}{83} \\ \\ y = 0.7771459615 \times 83 \\ \\ y = 64.5031148 \\ \\ \huge \red{ \boxed{ y = 64.50 \: cm}}$
