The expression (2)(3)(4)(5)6)  shows repeated multiplication.

(2)(3)(4)(5)6)   = 2 × 3 × 4 ×5 × 6 has the repeated multiplication expression

Step-by-step explanation:

given expressions are

i)  (1)9)       ii) (190       iii) (77)77)       iv) (2)(3)(4)(5)6)        v) (9(99999)

×

i)  (1)9) = 1×9  

ii) - (190      = - 190

ii) (77)77)  = 77 × 77

iv) (2)(3)(4)(5)6)   =2 × 3 × 4 ×5 × 6

v) (9(99999) = 9 × 99999

Here , we need to find out the repeated multiplication expression ,

Hence., (2)(3)(4)(5)6)   = 2 × 3 × 4 ×5 × 6 has the repeated multiplication expression

Kyle soles 18 of 24 puzzles in a puzzle book. he says that he can use an equivalent fraction to find the percent of puzzles in t
tino4ka555 [31]

Answer:

He solved 75% of the puzzles!

Step-by-step explanation:

Okay, let's look at our fraction 18 out of 24. We can see that they are both even numbers, so at worst, we can divide the entire fraction by two. However, they have a GCF of six, so we will use that.

18                               3

----  divided by 6  =  ----

24                              4

Now that we have the fraction 3/4, we can turn that into a percentage!

3/4 is 0.75. To get the percentage, we multiply that by 100--now we have 75%.

The average mass of an ant is approximately 3 × 10 − 3 grams. The average mass of a giraffe is approximately 2 × 10 3 kilograms.
Vika [28.1K]

Given that average mass of an ant = 3 \times 10^{-3}grams.

Given that average mass of a giraffe = 2 \times 10^{3} Kilograms.

Now we have to find about how many times more mass does a giraffe have than an ant. Before carring out any comparision, we must make both units equal.

Like convert kilogram into gram or gram into kilogram.

I'm going to convert kilogram into gram using formula

1 Kg = 1000 g


So the average mass of a giraffe = 2 \times 10^{3} *10^3 grams.


Now we just need to divide mass of giraffe by mass of ant to find the answer.

\frac{2 \times 10^{3} *10^3 }{3 \times 10^{-3} }

= \frac{2 \times 10^{3} *10^3 *10^{3}}{3  }

= \frac{2 \times 10^{3+3+3}}{3  }

= \frac{2 \times 10^9}{3  }

= \frac{2}{3  } \times 10^9

=666666666.667

Hence final answer is \frac{2}{3  } \times 10^9 which is approx 666666666.667.

Carson's wheelbarrow can hold 345 pounds. If he has 121 pound of rock in the wheelbarrow what number of pounds p can he pull wit
dangina [55]

Answer:

p\leq 224\ lb

The maximum number of pounds p is 224

Step-by-step explanation:

Let

p ----> the maximum number of pounds he can pull without going over the weight limit

we know that

121 pound of rock in the wheelbarrow plus p pounds must be at most 345 pounds

In this problem the word "at most" means "less than or equal to"

so

The inequality that represent this situation is

p+121\leq 345

solve for p

subtract 121 both sides

p\leq 345-121

p\leq 224\ lb

therefore

The maximum number of pounds is 224
