Which sentence contains an error in word usage​

SAT
1 answer:
slava [35]4 years ago
3 0

Answer: The answer is B, "Jon was surprised when it did not take him long to learn three cords on the guitar"

Explanation: "Cords" is a type of rope and therefore incorrect in the context of the sentence. Instead, it should be "chords" because Jon is learning to play a musical instrument, and chords refers to a group of harmonized notes used in music.

The lengths of two sides of an isosceles triangle are eight and 10. what is the length of the third side
leva [86]

The length of the third side can be either 10 or 8, if the lengths of two sides of an isosceles triangle are eight and 10.

According to the given question.

The lengths of two sides of an isosceles triangle are 8 and 10.

Since, the properties of an isosceles triangle are

  • Two sides are congruent to each other.
  • The sum of the length of the two sides of a triangle is greater than the length of the third side.
  • The difference between the two sides of a triangle is less than the length of the third side.

So, according to the property of an isosceles triangle

The third side must be less than the sum of 8 and 10.

⇒ length of third side < 8 + 10

⇒ length of third side < 18

And,

Length of the third side > 10 - 8

⇒ length of the third side > 2

But, the triangle is an isosceles triangle therefore, the third side must be either 8 or 10.

And

8 or 10 both are less than 18 and greater than 2.

Therefore, the length of the third side can be either 10 or 8.

Quadrilateral ABCD is similar to quadrilateral EFGH.
Inessa [10]

Answer:

s = 11

Explanation:

Given

The attachment completes the question.

Required

Find s

Because ABCD and EFGH are similar, then:

\frac{AB}{CD} = \frac{EF}{GH}

From the attachment:

AB = 2s

CD = 3s - 3

EF = 5.5

GH = 7.5

So, we have:

\frac{2s}{3s - 3} = \frac{5.5}{7.5}

Cross Multiply

2s * 7.5 = 5.5(3s - 3)

Open bracket

2s * 7.5 = 5.5*3s - 5.5*3

15s = 16.5s - 16.5

Collect Like Terms

15s - 16.5s = - 16.5

-1.5s = - 16.5

Make s the subject:

s = \frac{-16.5}{-1.5}

s = \frac{16.5}{1.5}

s = 11

<em>Hence, the value of s is 11 m</em>

HURRY THE F^CK UP AND ANSWER.
Evgesh-ka [11]

Answer:  These apply as goals of the United Nations:

<em>(▢ establishing human rights )</em>

<em>▢ preventing war </em>

<em>(▢ promoting social progress )</em>

<em>▢ encouraging international cooperation </em>

The UN does not seek to take over aggressive nations in a military way, nor does it set up an international military tribunal.   It will provide peacekeeping forces to regions of conflict.  

The UN Charter, signed in 1945, lists the purposes of the organization in Chapter I, Article 1.  Here's the official wording as found in the Charter:

The Purposes of the United Nations are:

To maintain international peace and security, and to that end: to take effective collective measures for the prevention and removal of threats to the peace, and for the suppression of acts of aggression or other breaches of the peace, and to bring about by peaceful means, and in conformity with the principles of justice and international law, adjustment or settlement of international disputes or situations which might lead to a breach of the peace;

To develop friendly relations among nations based on respect for the principle of equal rights and self-determination of peoples, and to take other appropriate measures to strengthen universal peace;

To achieve international co-operation in solving international problems of an economic, social, cultural, or humanitarian character, and in promoting and encouraging respect for human rights and for fundamental freedoms for all without distinction as to race, sex, language, or religion; and

To be a centre for harmonizing the actions of nations in the attainment of these common ends.
