Rewrite the question in an "equation way":

(some fish) = (man buys) + (boy buys) + (left)

(some fish) = 2 + 4 + 3

(some fish) = 9

Kelly saw 9 fish at first.

Consider the original complex figure and the reduction.
Dmitriy789 [7]

Answer:

1/8

Step-by-step explanation:

I'm going to try to explain this as easy as possible. What I did was take the original shape and divide it by the new shape. For this question, I solved it by dividing 32(the original base) by 4(the new base) and got 8. So the scale factor of the reduction was 1/8.

Please help me find the values of these irraational numbers on a number line!!!
uranmaximum [27]
Here, You have to simplify every number to their simple form and place it on the arrow by approximation:

So, Here is your answers:

Upper Arrows (From Left towards right):
1st = -10√2/3
2nd = -√7
3rd = ∛4
4th = √50

Lower Arrows (From Left towards right):
1st = -√99
2nd = -√17
3rd = ∛9
4th = π

Hope this helps!

What is the length of line segment PQ? If you can please explain, thanks.
nydimaria [60]

Given:

Tangent segment MN = 6

External segment NQ = 4

Secant segment NP =x + 4

To find:

The length of line segment PQ.

Solution:

Property of tangent and secant segment:

If a secant and a tangent intersect outside a circle, then the product of the secant segment and external segment is equal to the product of the tangent segment.

\Rightarrow NQ\times NP = MN^2

\Rightarrow 4\times (x+4) = 6^2

\Rightarrow 4x+16 = 36

Subtract 16 from both sides.

\Rightarrow 4x+16-16 = 36-16

\Rightarrow 4x =20

Divide by 4 on both sides.

$\Rightarrow\frac{4x}{4}=\frac{20}{4}

\Rightarrow x = 5

The length of line segment PQ is 5 units.

Write an expanded form and find the sum . plzz solve it 100% right... <br>​
harina [27]

Step-by-step explanation:

n = 0 : 2(0) -1 = -1

n = 1 : 2(1) - 1 = 1

n = 2 : 3

n = 3 : 5

n = 4 : 7

n = 5 : 9

sum = -1 + 1 + 3 + 5 +7 + 9 = 25
