Answer:

1)6

2)20

3)45

Step-by-step explanation:

a=1/2 bh

1) 4*3=12/2=6

2) 8*5=40/2=20

3)15*6=90/2=45

Answer:

1) 6

2) 20

3) 45

Step-by-step explanation:

To find the area of a triangle, use the formula [tex]\frac{1}{2} bh[/tex], where [tex]b[/tex] represents the length of the base, and [tex]h[/tex] represents the height. In the first triangle, the base length is 4 and the height is 3, so the area is 6. In the second triangle, the base length is 5 and the height is 8, so the area is 20. In the third triangle, the base length is 15 and the height is 6, so the area is 45.

Answer: Looks like u already answered the question

Step-by-step explanation:

The expression 4[(3/4)y - 2 + (1/2)y] is equivalent to the expression 5y - 8 and 3y - 8 + 2y.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The expression is given below.

⇒ 4[(3/4)y - 2 + (1/2)y]

Simplify the expression, then we have

⇒ 4[(3/4)y - 2 + (1/2)y]

⇒ 3y - 8 + 2y

⇒ 5y - 8

The expression 4[(3/4)y - 2 + (1/2)y] is equivalent to the expression 5y - 8 and 3y - 8 + 2y.

Step-by-step explanation:

Answer:

Total cost of footpath = 528 m²

Step-by-step explanation:

Width of footpath is 2m.

Thus,

For longer footpath, there will be two sides. Thus; area = 2(24 + 2 + 2) × 2 = 112 m²

For shorter footpath, since the 2 longer sides have been taken care of, length remains 16m. Then area = 2(16 × 2) = 64 m²

Total area = 112 + 64 = 176 m²

cost to tile foot path is $3 per square metres.

Total cost of footpath = 176 × 3

Total cost of footpath = 528 m²

Answer:

Step-by-step explanation:

Answer:

E = 12.20(h) - 7.15

h = 6.82 hours

Given:

Pay hour = $12.20 per hour

Bus fare = $7.15

1.Equation:

Assume

She has work for "h" hours

Total earning = E

So,

E = 12.20(h) - 7.15

If,

Total earning = E = $90.45

So,

E = 12.20(h) - 7.15

90.45 = 12.20(h) - 7.15

h = 6.82 hours

Step-by-step explanation:

Use the distributive property to multiply 6 to the values given in the parentheses.

6(a - b + 4)

6 x a = 6a

6 x - b = 6b

6 x 4 = 24

Combine them:-

V = volume of cube - volume of sphere

   = 7³ - [tex]\frac{4}{3}[/tex] πr³ ( r is the radius and r = 7 ÷ 2 = 3.5 )

   = 343 - [tex]\frac{4}{3}[/tex] π × 3,5³

Answer:

C. -1

Step-by-step explanation:

Find the y intercept by plugging in the slope and a given point into the equation y = mx + b. Then, solve for b:

y = mx + b

-7 = -3(2) + b

-7 = -6 + b

-1 = b

So, the y intercept is -1.

The correct answer is C. -1

Complete question is;

Which properties are necessary to claim that the two prisms are congruent? Check all that apply.

1) The lengths of corresponding edges are in a 1:1 ratio.

2) The volumes are equal.

3) Corresponding angles have different measures.

4) Corresponding faces are not congruent.

5) The base areas are equal.

6) The prisms have the same height

Answer:

1) The lengths of corresponding edges are in a 1:1 ratio

2) The volumes are equal.

5) The base areas are equal.

6) The prisms have the same height

Step-by-step explanation:

For two prisms to be congruent, it means they are similar with the following properties;

Each pair of their corresponding angles must be the same.

Each pair of their corresponding lengths must have same ratio.

The ratio of their corresponding lengths will have to be 1:1

Also, they must have same volume and same height.

Thus, looking at the options, the correct ones are 1,2,5,6
