Answer:

5a) x=40   using the formulae for perimeter of a rectangle p=2(l+b)

120=2(l+20) factor out and you have 120=2l+40   make L subject of formulae then you have 2L=120-40   so L=80/2    L=40cm.

(5b) use the same procedure p=2(l+b)   then L=250m.

6a) since both area and perimeter are give then using p=2(l+b),  20=2(L+B)  so (L+b)=20/2    therefore (L+b)=10  

Now introduce the formular for area which is A=L*B   24=L*B     then making L sub of formular L=24/B    substitute into (L+B)=10  then u have 24/B +B =10 find LCM  you then have 24+B^2=10B   this becomes a quadratic equation  B^2 -10B +24 =0 solve and  you have B=4 or 6.   Substitute into (L+B)=10 to find L.  L= 4 or 6

6b) use the same procedure as 6a.

L=2 or 12 and W =12 or 2

Ayumi plans to go blueberry piking before school, which starts at 8:00 am the amount of blueberries B, in cups that alum picks g
Trava [24]

Answer:

M(t) = M(16 - 2·t)

Step-by-step explanation:

The function is just formed by using the concept of composite functions.

B is cups of blueberries, and n is cups of blueberries,

So by substituting values the required equations formed are given by :

B(t) = 2·(8 - t)  

M(n) = 12·n  

n = B(t)  

M(t) = M(n)

       = M(B(t))

       = M(2·(8 - t))

       = M(16 - 2·t)

Therefore, this is the required function muffins M

Taylor states that 2,800,000 in scientific notation is 2.8 x 10 -6 because the number has six places to the right of the 2. Is T
soldier1979 [14.2K]

Scientific Notation is the way of <u>writing a number or expressing them</u> in a <u>shorter or more compact way.</u>

No, <u>Taylor's resoning is incorrect</u> because  2,800,000 = 2.8  * 10^{6}

From the question, we are given:

2,800,000 .

2,800,000 in scientific notation is  2.8  * 10^{6}.  

The reason the power is not to the negative 6 is that we are moving from the right-hand side to the left-hand side 6 times.

Therefore, <u>Taylor's reasoning is incorrect. </u>

Find the value of x in the triangle shown below.
MrMuchimi

Answer: 102 degrees

Step-by-step explanation:

This is an isosceles triangle because two of the sides are the same length which means that two angles are congruent as well.

180-(2(39))

=180-(78)

=102

Which is equal to log base 2n=4
o-na [289]
To solve this problem you must apply the proccedure shown below:

 1. You have the following logarithm:

 <span>log(2)n=4

 2. Therefore, you con rewrite it as below:

 loga(b)=logb/loa
</span>
 3. Therefore, you have:

 log(2)n=4⇒log(n)/log(2)=4
 
 4. Then, you obtain:

 log(n)=4log(2)

 5. Therefore, as you can see, the answer for the exercise shown above is the last option, which is:

 log(n)=4log(2)
