Mathematics
1 answer:
insens350 [35]3 years ago
5 0

Answer:

x = 45°

Step-by-step explanation:

From the triangle given in the picture,

It's given that two sides of the triangle are equal so the triangle is an isosceles triangle.

By the property of isosceles triangle,

Opposite angles of the equal sides are equal in measure.

By triangle sum theorem,

x + x + 90° = 180°

2x + 90 = 180

2x = 180 - 90

x = \frac{90}{2}

x = 45°

isabella Went hiking she climbed park way up a mountain and stopped to have lunch then she climbed down. which graph could rep
Natali5045456 [20]

Answer:

Step-by-step explanation:

The speed one (c) is a red herring. Nothing we can see measures her speed.

The only graph that could possibly represent the right answer is D (first graph from the right). It shows that she topped 1/2 way up. It also shows that she took her time about coming down when she was at the top.

The only thing we don't know is A. What's on the vertical axis?

In the equation below a is a number between 0 and 1 8 x a = b which statement about the value of b is always true
Kamila [148]

Answer:

See Explanation

Step-by-step explanation:

Given

0 \le a \le 1

8*a =b

Required

Determine the true statement about b

The question is incomplete as options are not given. However, a general explanation is as follows:

Rewrite 8*a =b

b = 8 * a

When a = 0

b = 8 * 0 = 0

When a = 1

b = 8 * 1 = 8

This means that:

For 0 \le a \le 1

Then 0 \le b \le 8

<em>This means that: b is a number between 0 and 8</em>

How much of 30% HCI and 45% HCI would be needed to mix and produce 50 liters of 35% HCI
VladimirAG [237]

Answer:

  • 33 1/3 liters of 30%
  • 16 2/3 liters of 45%

Step-by-step explanation:

Let x represent the liters of 45% solution needed. Then the amount of HCl in the mix is ...

  0.45x +0.30(50 -x) = 0.35(50)

  0.15x = 0.05(50) . . . . . simplify, subtract 0.30(50)

  x = (0.05/0.15)(50) = 50/3 = 16 2/3 . . . liters of 45% HCl

33  1/3 liters of 30% and 16 2/3 liters of 45% HCl are needed.

_____

<em>Comment on the solution</em>

You may notice that the general solution to a mixture problem of this sort is that the fraction of the mix that is the highest contributor is ...

  (mix % - low %) / (high % - low %) = (.35 -.30) / (.45 -.30) = .05/.15 = 1/3
