Um, we see that the slice created the triangle, and the formula to find the area of the triangle:
1/2×B×h where B represent Base and h represent height.
In this case, Base=5 cm
Height=11 cm
A=1/2×11×5
A=5.5×5
A=27.5 square cm. As a result, the area of the resulting two-dimensional cross section is 27.5 square cm. Hope it help!

(u+v)*2+2(u+v)-3 factorise it completely it's a challenge

lions [1.4K]

If you mean

$(u+v)^2+2(u+v)-3$

you can first substitute $x=u+v$ to get

$x^2+2x-3=(x+3)(x-1)$

and so

$(u+v)^2+2(u+v)-3=\boxed{(u+v+3)(u+v-1)}$

The spinner shown is divided into 8 equal sections. What is the probability that the arrow will land on a section labeled with a

Oxana [17]

The probability of the arrow will land on a section labeled with the number greater than 3 is $\frac{5}{8}$

Step-by-step explanation:

Given,

The spinner is divided into 8 sections say named 1, 2, 3, 4, 5, 6, 7, 8

To find the P : probability of the arrow will land on a section labeled with the number greater than 3

Formula

P = (the number of possible outcomes) ÷ ( the number of total result)

We will count the probability when the arrow land on either 4 or 5 or 6 or 7 or 8 = 5 times

Total number of result = 8

Hence the probability = $\frac{5}{8}$

What is a simplified form of the expression (5^2)-^2Divided by 5^3

laila [671]

Answer:

5^ -7 =1 / 5^7

Step-by-step explanation:

(5^2)-^2/ 5^3

We know that a^b^c = a^(b*c)

(5^2)-^2 = 5^(2*-2) = 5^-4

5^-4/ 5^3

We know that a^b /a^c = a^ (b-c)

5 ^ (-4-3)

5^ -7

If we don't want to use negative exponents

We know that a^ -b = 1/ a^b

1 / 5^7

Answer:

12. 14 - 9 = 5

13. 8 + 4 = 12

14. 28/7 = 4

15. 9 x 3 = 27
