Manuel wants to build a model of Captain America's famous shield out of cardboard. The outer ring of the shield is colored red.

zmey [24]

Answer:

615.44 in²

Step-by-step explanation:

The shape of Captain America's shield = Circular

The area of a circle = πr²

The radius of the whole shield = 14 inches.

The first ring = Red ring

Hence, the area of the red ring =

π = 3.14

3.14 × 14²

= 615.44 in²

The area of the space he needs to paint red is 615.44 in²

What is the value of the expression?

Blababa [14]

Answer:

- $\frac{9}{10}$

Step-by-step explanation:

Step 1: Add the numerator fractions.

2/5 + 3/10

Here we have to find LCD, the LCD of 5 and 10 is 10

(2*2) + 3 4 + 3

Therefore, 2/5 + 3/10 = --------------- = ------------------

10 10

= 7/10

Step 2: Now substitute 2/5 + 3/10 = 7/10 in the given fraction, we get

7/10

= ----------

-7/9

If we have fraction over fraction, we have to find the reciprocal of denominator fraction and multiply.

The reciprocal of -7/9 is -9/7

Step 3: Now multiply 13/10 and -9/7

= (7/10) x (-9/7)

= -9/10

=-9/10

The answer is - $\frac{9}{10}$

Answer:

$\frac{1}{8}$ = $\frac{b}{4^{2} }$

b = $\frac{1}{8}$ × $4^{2}$

b = $\frac{4^{2} }{8}$

then b = $\frac{c^{2} }{a}$ that is ORANGE

-2 - v = -7

v = -7 +2

then v = k + m that is BROWN

$\frac{14}{q}$ = $\frac{-7}{-4}$

q = $\frac{14 * -4 }{-7}$

then q = $\frac{ps}{r}$ that is YELLOW

4m + 2(n) = 5 (n)

4m = 5 (n) - 2n

4m = 3n

m = $\frac{3n}{4}$

then m = $\frac{3n}{4}$ that is RED

-8 = $\frac{x}{-5}$ - 6

$\frac{x}{-5}$ = -8 + 6

x = -5 (-8 + 6)

then x = y( w + z ) that is LIGHT GREEN

How do i do this?????????

Gnom [1K]

Answer:

x≥5

Step-by-step explanation:

-1 ≥ x/-5

x/-5 ≤ -1

x(-1)/5 ≥ (-1) (-1)

x/5 ≥ 1

5x/5 ≥ 1 ×5

x ≥ 5

I'm not sure but I tried.

For the graph: you can draw a line about 15cm, put 0 at the start then after 5cm put 5 then 10 at 10cm and 15 at the end. At 5 put • that's the starting and go all the way to 15 and add > to show that the line continues. I'm not good at explaining but I hope it helps.
