Answer:

12 [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Put 5 in fraction form ( [tex]\frac{5}{1}[/tex] ) and multiply it by [tex]\frac{5}{2}[/tex]

[tex]\frac{5}{1}[/tex]×[tex]\frac{5}{2}[/tex] = [tex]\frac{25}{2}[/tex]   now simplify  to 12 [tex]\frac{1}{2}[/tex]

Answer:

95 cm^2

Step-by-step explanation:

perimeter(p)=39cm

L=3x-1

B=2x+3

Now,

p=2(l+b)

39=2(3x-1+2x+3)

39=6x-2+4x+6

39=10x+4

39-4=10x

x=35/10

x=3.5

Putting the value of x

L=3x-1; =3×3.5-1; =10.5-1; =9.5cm

B =2x+3; =2×3.5+3; =7+3; =10cm

Again,

A= L×B

=9.5×10

=95cm^2

Answer:

x=9                   x=-1

Step-by-step explanation:

2(x-4)^2=50

Divide each side by 2

2/2(x-4)^2=50/2

(x-4)^2=25

Take the square root of each side

sqrt((x-4)^2)=sqrt(25)

x-4 = ±5

x-4 =5            x-4 = -5

Add 4 to each side

x-4+4=5+4    x-4+4 = -5+4

Answer:

It took Riley 9 hours to clean the garage.

Step-by-step explanation:

With the information provided, you can say that the amount Riley earns for cleaning the garage is equal to the price per hour for the number of hours it takes to clean the garage, which can be express as:

x=4.25y, where:

x is the amount Riley earns for cleaning the garage

y is the number of hours it takes to clean the garage

Now, you can replace x with $38.25 that is the amount that Riley earned and you can solve for y to find how long it took her to clean the garage:

38.25=4.25y

y=38.25/4.25

x=9

According to this, the answer is that it took Riley 9 hours to clean the garage.

8*22 = 22*8

Answer: [tex]15\times\frac{1}{2}[/tex]

Explanation:

Multiplying by 1/2 is the same as dividing by 2.

For example, if you have 10 slices of cake and 2 friends, then each friend gets 10/2 = 5 slices. We could also say [tex]10\times \frac{1}{2} = 5[/tex]

The fraction 1/2 converts to the decimal form 0.5, which means [tex]10 \times \frac{1}{2} = 10*0.5[/tex]

Answer:

6 * 10^2

Step-by-step explanation:

Simplify : (4.2×10^7)÷(7×10^4)

(4.2 × 10^7) / (7 × 10^4)

From indices : 10^a ÷ 10^b = 10^(a - b)

(4.2 / 7) * 10^(7-4)

0.6 * 10^3

= 6 * 10^2

Hence, (4.2×10^7)÷(7×10^4) = 6 * 10^2

Answer: 720

Step-by-step explanation:

From the question, we are informed that cthe researches counted 400 turtles, of which 20 were marked. This implies that 20/400 = 1/20 were marked.

If the researchers wanted to track the reptile population around a lake, and the researchers marked 36 turtles, the estimate of the total population will then be:

1/20 × x = 36

x/20 = 36

x = 20 × 36

x = 720

The turtle population is 720

Step-by-step explanation:

After dilation of ΔABC, the length of B'C' = 8m and ∠A' = 28°.

Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.

When the triangle undergoes dilation, the length of its sides gets multiplied by 1/2 (dilation factor) but the angles remain the same ( since, the shape has to remain same).
