Answer:

answers are in the attached file!

Step-by-step explanation:

these are super simple to solve if you break it down! in order to turn a mixed number into an improper fraction, you first need to multiply the whole number by the denominator of the fraction. then, you add the numerator of the fraction to the product of the multiplication problem. that answer is then the new numerator of the fraction! the denominator will stay the same.

for example, the very first one that is given in the picture is 6 1/2. 6•2 equals 12, plus the numerator, 1, gives 13.

Tristán wants to build a square garden in his backyard if the garden is going to be 64 ft2 how many feet of material will he nee

Alex777 [14]

Answer:

Tristan will need 32 feet of material for the perimeter of the garden.

Step-by-step explanation:

Given that

Area of square garden = A = 64 square feet

Perimeter = P = ?

We know that for calculation of perimeter, length of side of square is required which is not directly given in the question. The area will be used to calculate length of side and then length will be used to calculate the perimeter.

So,

$Area = A = s^2$

s is for side

Putting the value of area

$64 = a^2$

Taking square root on both sides

$\sqrt{s^2} = \sqrt{64}\\s = 8\ feet$

The length of side is 8 feet.

Perimeter will be:

$P = 4*s\\P = 4*8\\P = 32\ feet$

Hence,

Tristan will need 32 feet of material for the perimeter of the garden.

$\cfrac{(12-5)^7}{\left((3+4)^2\right)^2}= \cfrac{7^7}{(7^2)^2} =\cfrac{7^7}{7^4}=7^{7-4}=7^3=343$

what are a) the ratio of the perimeters and b) the ratio of the areas of the larger figure to the smaller figure? the figures ar

Alla [95]

We know that

a) find the ratio of the perimeters

the ratio of the perimeters is equal to the scale factor
scale factor=26/6-----> 13/3
the answer Part a) is
the ratio of the perimeters is 13/3

b) find the ratio of the areas of the larger figure to the smaller figure
we know that
area larger figure=[scale factor]²*area smaller figure
scale factor²=area larger figure/area smaller figure

the ratio of the areas of the larger figure to the smaller figure is equal to scale factor squared
scale factor²=(13/3)²----> 169/9

the answer Part b) is
169/9

the complete answer is
13/3 and 169/9
