The sum of three times a number and -4 is at least twice the number plus 8

Answer:

1. 27.0 m

2. 28.0 degrees

Step-by-step explanation:

1. AB

To find AB, we start by getting the measure of the third angle A

Mathematically;

A + 90 + 51 = 180

The sum of angles in a triangle is 180

A = 180-90-51

A = 39

We then proceed to use the sine rule

Mathematically, the sine rule states that the ratio of the measure of a side and the sine of the angle facing the side is same for each side of the triangle

Thus, with respect to the given triangle;

17/sin 39 = x/sin 90

x = 17sin90/sin 39

x = 27.0 m

Kindly note that we substituted x for AB

2. To find the measure of angle A we use the sine rule as used above, but here we have a missing angle and not a missing side

Thus;

34/sin 127 = 20/sin A

Sin A = (20 sin 127)/34

sin A = 0.469

A = sin^-1 0.469

A = 28.0 degrees

Answer:

Short-term investments, also known as marketable securities or temporary investments, are those which can easily be converted to cash, typically within 5 years. Many short-term investments are sold or converted to cash after a period of only 3-12 months. Some common examples of short term investments include CDs, money market accounts, high-yield savings accounts, government bonds and Treasury bills. Usually, these investments are high-quality and highly liquid assets or investment vehicles.

Given that:

Total yards of satin bought by Maddie = [tex]3\frac{2}{3}[/tex] yards

Number of yards required make one ribbon = [tex]\frac{2}{3}[/tex] yards

To find:

Number of complete bows that can be made ?

Solution:

First of all, let us learn about converting the mixed fraction to fractional form.

Formula:

[tex]a\dfrac{b}{c} = \dfrac{a\times c+b}{c}[/tex]

Therefore, total yards of satin bought by Maddie can be written in fractional form as:

[tex]3\dfrac{2}{3} = \dfrac{3\times 3+2}{3} = \dfrac{11}{3}[/tex]

One hair bow requires [tex]\frac{2}{3}[/tex] yards of ribbon.

Number of hair bows that can be made, can be found by dividing the total ribbon length by ribbon required for making one hair bow.

Answer is:

[tex]\dfrac{\frac{11}{3}}{\frac{2}{3}}\\\Rightarrow \dfrac{11\times 3}{2\times 3}\\\approx 4[/tex]

4 hair bows can be made.

Answer:

0.25

Step-by-step explanation:

1.75/7 would equaln0.25, use your calculator if you have one

The decimal 1.75 when divided by the number 7 gives the decimal 0.25.

In mathematics, a decimal is a base-10 numeral system applied to characterize real numbers. It's known as "decimal" because it uses ten dissimilar symbols, videlicet the digits 0 through 9, to portray all achievable values. The decimal system is the most generally used numeral system in day-to-day life.

The decimal system works on a positional memorandum principle, where each digit's position determines its value within the number.

The decimal 1.75 can be written as a fraction as follows:

[tex]1.75 = \dfrac{175}{100}[/tex]

      [tex]= \dfrac{7}{4}[/tex]

To divide 1.75 by 7, let's divide [tex]\dfrac{7}{4}[/tex] by 7.

[tex]\dfrac{7}{4} \div 7\\= \dfrac{7}{4} \times \dfrac{1}{7}\\= \dfrac{1}{4} \times 1\\= \dfrac{1}{4}\\= 0.25[/tex]

Thus, 0.25 is 1.75 divided by 7.

Answer:

[tex]T_n = -97n[/tex]

Step-by-step explanation:

The actual sequence is: -97, -194, -291, -388

Required

Determine the nth term

nth term of an arithmetic progression is:

[tex]T_n = T_1 + (n - 1)d[/tex]

Where

[tex]T_1 = First\ Term = -97[/tex]

[tex]d = Common\ Difference = -194 - (-97) =-97[/tex]

So:

[tex]T_n = T_1 + (n - 1)d[/tex] becomes

[tex]T_n = -97 + (n - 1) * -97[/tex]

[tex]T_n = -97 -97n + 97[/tex]

Collect Like Terms

[tex]T_n = -97n + 97-97[/tex]

[tex]T_n = -97n[/tex]

Hence, a term of the sequence is:

Answer:

b on edge, 16.3

Step-by-step explanation:

trust

The angle between the two given vectors is 16.26°

Here we have the vectors u = (3, 4) and y = (4, 3).

We know that:

u*y = |u|*|y|*cos(θ)

Then:

u*y = 3*4 + 4*3 = 24

And:

|u| = √(3^2 + 4^2) = √25 = 5 = |y|

Then we have:

24 = 5*5*cos(θ)

24/25 = cos(θ)

To find theta, we apply the inverse cosine function in both sides:

Acos(24/25) = θ = 16.26°
