Answers

Answer 1

Answer:

Answer:

P(spades) = 7/10

Step-by-step explanation:

there are 10 different cards that can be picked, out of which what we want to pick is spades which are 7. and so there are 7 chances that we will get to pick spades out of all the 10 possibilities. hope it is easy to understand

Triangle ABC is an isosceles right triangle. What is the measure of a base angle?

Answers

Answer:

The measure of base angle is 45°

Step-by-step explanation:

Given that triangle ABC is an isosceles right triangle.

we have to find the measure of base angles.

As given triangle is right angled triangle therefore one angle which is not a base angle is of 90°

Also the triangle ABC is isosceles therefore two sides of triangle are equal and angles opposite to the equal sides are equal.

Let these equal angles which are base angles is x°

By angle sum property of triangle,

the sum of all angles of triangle equals to 180°

∠A+∠B+∠C=180°

$x^(\circ)+90^(\circ)+x^(\circ)=180^(\circ)$

$2x^(\circ)+90^(\circ)=180^(\circ)$

$2x^(\circ)=90^(\circ)$

$x^(\circ)=(90)/(2)=45^(\circ)$

Hence, the measure of base angle is 45°

If Triangle ABC is an isosceles right angle, base angle would be equal to 45 degree. It is because, in an isosceles right triangle, two angle remains equal (45) and one is larger.(90)

In short, Your Answer would be 45

Hope his helps!

Raymond just got done jumping at Super Bounce Trampoline Center. The total cost of his session was \$43.25$43.25dollar sign, 43, point, 25. He had to pay a \$7$7dollar sign, 7 entrance fee, and \$1.25$1.25dollar sign, 1, point, 25 for every minute he was on the trampoline.

Answers

Answer:

29 minutes

Step-by-step explanation:

Given

$Total = \$43.25$

$Entrance\ Fee = \$7$

$Per\ Minute = \$1.25$

Required

Determine the number of minutes (t) that he was on the trampoline.

This can be expressed as:

$Total\ Payment = Entrance\ Fee + Amount\ per\ minute * t$

Where t represents the number of minutes

Substitute values for Total, Entrance Fee and Amount per minute

$43.25 = 7 + 1.25 * t$

$43.25 = 7 + 1.25t$

Solving further to get the value of t, we have:

$1.25t = 43.25 - 7$

$1.25t = 36.25$

$t = 36.25/1.25$

$t = 29$

Answer:

29 minutes

Step-by-step explanation:

7 + 1.25t = 43.25 is the equation

How did I solve this?

I divided those two and that is how you get the equation

In total is 29 minutes

I did the Khan and it was right!

Find the absolute value of the complex number -3 - 6i.a.
6.07
c.
6.7
b.
6.17
d.
6.71

Please select the best answe

Answers

Answer: 6.71

Explanation:

1) The absolute value of a complex number a + bi is √ [ (a)² + (b)²]

2) The given number - 3 - 6i is equivalent to (-3) + (-6)i, so you see that a = -3 and b = - 6.

3) Therefore, the absolute value is √ [ (-3)² + (-6)² ] = √ [ 9 + 36] = √(45) ≈ 6.708 ≈ 6.71
