A 40 x 110 rectangle has an area of 4400 sq. ft.

The horse has a 14 ft lead. That makes 14 ft. the radius that the horse can cover.

The formula for the area of a circle is r^2 * PI ( radius squared * 3.14 ).

So the horse can't get to 4400 - ( 14 * 14 * 3.14 ) sq. ft.

The rabbit population in a certain area is 200% of last year's population. There are 900 rabbits this year. How many were ther

Nezavi [6.7K]

There would be 450 rabbits last year.

Since 900 is double 450, 200% of 450 is 900. (450 would be 100%, so you would double it).

To find the product of 42.12 and 10³, move the decimal point in 42.12 __ places to the right because 10³ has __ zeros.

Yakvenalex [24]

<h3>To find the product of 42.12 and 10^3, move the decimal point in 42.12 3 places to the right because 10^3 has 3 zeros</h3>

<em><u>Solution:</u></em>

Given that,

$\text{ product of } 42.12 \text{ and } 10^3$

Which means,

$42.12 \times 10^3$

Here, the exponent of 10 is positive ( which is 3)

When the exponent is positive, we have to move the decimal point to right

When you multiply a number by a power of 10, ( 10!, 10^2, and so on ) move the decimal point of the number to the right the same number of places as the number of zeros in the power of 10

Here, exponent is 3 , therefore move the decimal point right 3 places in 42.12

Therefore,

$42.12 \times 10^3 = 42120$

In the diagram m angle ACB = 61<br> Find m angle BCD

Marina86 [1]

we are given that

angle(ACF)=90

angle(ACB)=61

sum of all angles along any line is 180

so, we get

angle(ACF)+angle(ACD)=180

we can plug value

90+angle(ACD)=180

angle(ACD)=90

now, we can use formula

angle(ACD)=angle(ACB)+angle(BCD)

now, we can plug values

and we get

90=61+angle(BCD)

90-61=61-61+angle(BCD)

angle(BCD)=29................Answer

PLEASEE HELPP ME IM DESPERATE

miss Akunina [59]

Answer:

I can help with Q "4" as -

It uses triangle congruence test - here we use - SAS, as

one side is equal as it is given

both the angles are 90 degree

and they share a same side

so -

8x = 6x + 5

8x - 6x = 5

2x = 5

x = 2.5

RU = 6x+ 5 = 6 (2.5) + 5 = 20

( I am not so sure but I think this is the answer )
