Answer:

The answer should be a letter which is t.

Step-by-step explanation:

1) Simplify 2/3t to 2t/3.

$\frac{2t}{3} \times 1 \frac{1}{2}$

2) Convert 1 1/2 to improper fraction. Use this rule: a b/c = ac+b/c.

$\frac{2t}{3} \times \frac{1 \times 2 + 1}{2}$

3) Simplify 1 × 2 to 2.

$\frac{2t}{3} \times \frac{2 + 1}{2}$

4) Simplify 2 + 1 to 3.

$\frac{2t}{3} \times \frac{3}{2}$

5) Cancle 3.

$2t \times \frac{1}{2}$

6) Cancle 2.

$t$

Therefor, the answer for this equation is a letter which is t.

F(0) =2,and f(3) =5. if k =f(5),, whT is the value if k

Pachacha [2.7K]

The question in incomplete..f(x) maybe a polynomial of any degree and will yield varying results for each ..but assuming it's a linear equation , we would have f(x) = x +2 , So , F(5) = 7.

Find the area of triangle DEF with vertices D(-1,2), E(3,-2) and F(-2,-2).*

Veronika [31]

Answer:

The area of the triangle DEF is 10.

Step-by-step explanation:

Area of a Triangle:

A triangle of base B and height H (both must be perpendicular) has an area of:

$\displaystyle A=\frac{BH}{2}$

The image below shows the triangle formed by the points DEF. It's important to notice the points E and F lie on the same horizontal line because they both have the same y-coordinate.

This fact simplifies the calculations since we can easily compute the length the of base as the difference of their x-coordinates:

B=3-(-2)=3+2=5

Being the base of a horizontal line, the height of the triangle can be calculated as the difference of y-coordinates of D and the height of that line.

H=2-(-2)=4

With these two values, we calculate the area:

$\displaystyle A=\frac{5*4}{2}=10$

The area of the triangle DEF is 10.

The square below represents one whole.

grandymaker [24]

Answer:

Fraction: 81/100

Decimal: 0.81

Percentage: 81%

Step-by-step explanation:

The question is complete but the diagram mentioned can be found in

brainly.com/question/12188410

First step is to find the area of the whole square and then the area of the part that was shaded.

From the diagram, there are 100 squares in the whole square. 81 of those squares are shaded.

Area of the whole square = 10 by 10

= 10×10 = 100unit²

Area of shaded region = (10 by 8) + 1

= 80+1 = 81unit²

shaded area expressed as a fraction = 81unit²/100unit²

= 81/100

Shaded area expressed as a decimal = 81/100

You take the number 81 and carry the point by two decimal place from the right

= 0.81

Shaded area expressed as a percent of the whole = (81/100) × 100

= (81×100)/100

= 81%
