Answer:

B. 12 + 2pi cm

Step-by-step explanation:

The shaded region is made up of 3 square sides and one half circle. The three square sides are each 4, which means that those altogether equal 12.

The circle's circumference can be found by using the equation c = (d)pi

The diameter is 4, so the whole circumference is 4pi. However, you only need half of a circle, which is represented by 2pi.

Add them all together, and you get 12 + 2pi cm.

23 x 32 is the prime factorization for which one of these choices?
antoniya [11.8K]
<h2><u>Answer:</u></h2>

⟶ 2³ × 3² is the prime factorization for which one of these choices?

Let's check,

1) 6 = 3 × 2 [So, obviously not this choice]

2) 25 = 5 × 5 = 5² [Not this either]

3) 36 = 3 × 2 × 2 × 3 = 3² × 2² [Doesn't match with 2³ × 3²]

4) 72 = 2 × 2 × 2 × 3 × 3 = <u>2</u><u>³</u><u> </u><u>×</u><u> </u><u>3</u><u>²</u><u> </u>[Matches]

⟶ The answer is, choice <u>7</u><u>2</u><u>.</u>

Can someone please help with this maths !!!!!
ioda

Answer:

C)  -3

Step-by-step explanation:

Rearrange your equation so that it is in slope-intercept form (y = mx + b).  The m in the equation is the gradient.

y = 7 - 3x

y = -3x + 7

The m-value is -3.  This means that the gradient is -3.

Tatiana [17]

Hello! Your answer would be -10 degrees.

The temperature starts out eight degrees below zero. 0 - 8 = -8. Therefore, it starts off at -8 degrees.

Then, it increases by 5 degrees. Therefore, add 5 to -8. -8 + 5 = -3. Therefore, the next day has a temperature of -3 degrees.

Finally, it decreases by 7 degrees. -3 - 7 = -10. This shows us our final result - -10 degrees.

Hope this helps!
