Answer:

Volume = 113.1 cubic cm

Step-by-step explanation:

$Volume = \frac{4}{3} \pi r^3 = \frac{4}{3} \pi 3^3 = 4 \pi \times 9 = 36 \pi=113.1 cm^3$

Answer:

Using BODMAS

first solve division, then go for addition or subtraction

$1 \div 1 + al - m + 1 \div 1 + m - l\\ =(1 \div 1) + al - m +( 1 \div 1) + m - l\\ =1 + al - m + 1 + m - l\\ = 2 + al -l\\=2 + l(a - 1)$

Can you solve: 6/5=n+2/2n-3

OverLord2011 [107]

solving $\frac{6}{5}=\frac{n+2}{2n-3}$ we get value of n: $n=4$

Step-by-step explanation:

Solving the expression:

$\frac{6}{5}=\frac{n+2}{2n-3}$

Solving:

$\frac{6}{5}=\frac{n+2}{2n-3}\\Cross\,\,multiply:\\6(2n-3)=5(n+2)\\Simplifying:\\12n-18=5n+10\\Combining\,\,like\,\,terms:\\12n-5n=10+18\\7n=28\\n=\frac{28}{7}\\n=4$

So, solving $\frac{6}{5}=\frac{n+2}{2n-3}$ we get value of n: $n=4$

X+4Y=-8<br> find the x intercept:<br> find the y intercept: <br> graph the line.

galben [10]

Answer:

x-intercept = (-8, 0)

y-intercept = (0, -2)

Step-by-step explanation:

Given linear equation is: x + 4y = - 8

For x - intercept: Plug y = 0 in the above equation.

$\implies x +4(0) = -8\\\\\implies x +0 =-8\\\\ \implies x = -8\\\\ \boxed{\red{\bold{\implies x- intercept = (-8,\:0)}}}$

For y - intercept: Plug x = 0 in the given linear equation.

$\implies 0 +4y = -8\\\\\implies 4y=-8\\\\ \implies y = \frac{-8}{4}\\\\ \implies y = -2\\\\ \boxed{\purple{\bold{\implies y- intercept = (0,\:-2)}}}$

Can somebody help me please

It's an isosceles triangle so angles A and BCA are congruent.

Angle BCA is the supplement of BCD, so 180-109 = 71.

Angle A is congruent to that, so A=71 degrees.

Let's see if we can get that in the format they want, kind of as a proof.

1. ∠BCD=109° Reason: Given

2. AB ≅ BC Reason: Given

3. ∠BCA = 71° Reason: Linear pairs are supplementary

4. ΔABC is isosceles. Reason: Definition of isosceles

5. ∠A ≅ ∠BCA Reason: Isoceles triangle theorem

6. ∠A = 71° Reason: Def congruent

Answer: 71 degrees
