Use the formulas for the area of a triangle and the area of a rectangle for both figures. The bases are the tops and bottoms of the figures and the lateral sides are the sides not including the top or bottom. It’s basically just finding the areas of each side and adding them all up to find the surface area. Volume is finding the area of the base, using the triangle area formula, and multiplying that by the height of the figure
Hope this helps!

ILL GIVE YOU BRAINLIST !!!! What is the slope of this table?

VLD [36.1K]

Answer: Slope is m = 2/3

Step-by-step explanation:

-You have exactly four points on a table:

$(3,2) (6,4) (9,6) (12,8)$

-Use the slope formula and use any two points from those four points in order to find the slope:

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

-The two points I use are $(3, 2)$ and $(6,4 )$ for the equation:

$m = \frac{4 - 2}{6-3}$

$m= \frac{2}{3}$

So, the slope of the table is $\frac{2}{3}$ .

The radius of a circle is 4 feet. What is the length of a 90° arc? HELP ME PLEASE

Elza [17]

Answer:

6.3feet

Step-by-step explanation:

Given data

Radius= 4feet

The expression for the circumference of a circle is

C= 2πr

Substitute

C=2*3.142*4

C=25.136 feet

Also, a 90° arc is 1/4 of the circumference of a circle

Hence the length of the 90° arc is

=25.136/4

=6.284 feet

=6.3feet

If y = -x² + 14x + 7 , then x = 10 is a counterexample for which conjecture?

Misha Larkins [42]

Answer:

The correct answer is B

Step-by-step explanation:

If we plug in x=10 to the equation, we get y=47

Since y is positive, A is not an counterexample

Since y is a function of x, C is not an counterexample

Since the graph of y is a parabola, D is not an counterexample

Hope this helped and mark as brainliest!
