Answe is 75
we have a triangle with the area of 24 you remember that the triangle area has to be divided by two so it will be 12
then we have a normal rectangle which is 48
then we have 12+48 = 60
we have another triangle and the area of it would be 30÷2 would be 15
60+15=75 for your answer

Answer:

answer is 75 square feet

Step-by-step explanation:

area is length time width

8×6=48

to find area of triangle is length time witdht/height divided by 2

6×4=24/2=12

5×6=30/2=15

15+12+48=75

Find number of A intersection B? help me plz

Rom4ik [11]

Try this option:

1. to calculate the difference of the final sequence:

the difference between two terms of the sequence A is 4 (7-3=11-7=...=4) and the difference between two terms of the sequence B is 7 (9-2=16-9=...-7). It means, in the final sequence the difference should be 7*4=28;

2. to calculate the first term of the final sequence:

A={3;7;11;15;19;<u>23</u>;27;31;...;407} and B{2;9;16;<u>23</u>;30;...;709}. It means, the first term of the final sequence is 23.

3. to calculate the last term of the final sequence:

if 407<709, it means the last term is less than 407, then it is possible to make up the equation 23+28*n<407, where 23 - the 1st term of the final sequence, 28 - the difference of the final sequence, (n+1) - number of the last term of the final sequence and n∈Z.

n<(407-23)/28; n<13.71. If n∈Z, then n=13.

So, the last term of the final sequence is 23+28*13=387.

4. if the first term is 23, the last one is 387 and the difference of the final sequence is 28, then the final sequence is consists of 14 terms:

{23; 51; 79; 107; 135; 163; 191; 219; 247; 275; 303; 331; 359; 387}

how high up a vertical wall will a 26-foot-long extension ladder reach if its base is placed 10 feet away from the wall

allsm [11]

Answer:

24ft high

Step-by-step explanation:

Assuming the wall is perpendicular to the ground (so that it forms a right angle, and that when the ladder is placed on the ground and leaned up against the wall that it forms a right triangle), we can use the Pythagorean Theorem to describe the situation mathematically.

<h3><u>The Pythagorean Theorem</u></h3>

For any right triangle (a triangle that has a right angle) the Pythagorean Theorem applies. The Pythagorean Theorem describes the relationship between side lengths as $a^2+b^2=c^2$ , where "c" is the length of the "hypotenuse" (the side across from the right angle), and "a" and "b" are the lengths of the "legs" (the other two sides that are touching the right angle). Since addition is commutative, it doesn't matter which leg you pick for side "a" or side "b", it only matters that the hypotenuse must be "c".

Given that the ladder is across from the right angle (the angle formed by the wall and the ground... the two "legs"), the ladder represents the hypotenuse in this situation.

<h3><u>Substituting known values, and solving the equation</u></h3><h3> $a^2+b^2=c^2$ </h3>

Substitute known values, and simplify...

$a^2+(10)^2=(26)^2$

$a^2+100=676$

Subtract 100 from both sides...

$(a^2+100)-100=(676)-100$

$a^2=576$

Apply the square root property...

$\sqrt{a^2}=\pm \sqrt{576}$

$a=\pm 24$

$a=24$ or $a=- 24$

Since the distance height the ladder will reach is not a negative number, we reject the negative solution. Hence, the ladder will reach 24ft high, if placed 10ft from the base of the wall.
