A group of birds are flying, they meet another group of birds. They ask 'hello hundred.' They replied we are not 100. we need half of us plus you to be hundred. How many birds are needed?​

Given:

In triangle OPQ, o = 700 cm, p = 840 cm and q=620 cm.

To find:

The measure of angle P.

Solution:

According to the Law of Cosines:

[tex]\cos A=\dfrac{b^2+c^2-a^2}{2bc}[/tex]

Using Law of Cosines in triangle OPQ, we get

[tex]\cos P=\dfrac{o^2+q^2-p^2}{2oq}[/tex]

[tex]\cos P=\dfrac{(700)^2+(620)^2-(840)^2}{2(700)(620)}[/tex]

[tex]\cos P=\dfrac{490000+384400-705600}{868000}[/tex]

[tex]\cos P=\dfrac{168800}{868000}[/tex]

On further simplification, we get

[tex]\cos P=0.19447[/tex]

[tex]P=\cos^{-1}(0.19447)[/tex]

[tex]P=78.786236[/tex]

[tex]P\approx 79[/tex]

Therefore, the measure of angle P is 79 degrees.

Answer:

yes its decimal

Step-by-step explanation:

The given fraction into percent and decimal are; 2.8  and 280%

Percent counts the number compared to 100.

There is a fraction, containing numerator(upper value) and denominator(lower value).

So, if we have a%, that means for each 100, there are 'a' parts. If we divide each of them with 100, we get,

For each 1, there are a/100 parts.

Thus, 50% = 50/100 = 0.50 (in decimal)

There is a fraction, containing numerator(upper value) and denominator(lower value).

The mixed fraction contains a sum of whole number and a proper fraction.

WE have been given a fraction as;

Answer:

w = 6

Step-by-step explanation:

Solve

8w = 48

8w/8 = 48/8

Standard Form and Scientific Notation

What is standard form of numbers?

Standard form is the normal way of writing numbers no matter how big or small the number is.

Examples:

15,000,000

0.0000000678

What is scientific notation?

Scientific notation is a different way of expressing numbers. It is a short way of expressing very big numbers or very small numbers. It is also known as exponential form. Scientific notation is written as the product of a number and a power of 10.

Examples:

1.3 × 10⁶

34.5 × 10^⁻9

Going back to the question above, we need to convert the given scientific notation to its standard form.

Converting of Scientific Notation to Standard Form

To convert a number from scientific notation to standard form, move the decimal point.

The exponent tells the direction and the number of times we need to move the decimal point.

The positive exponent indicates a large number so we need to move the decimal point to the right.

The negative exponent indicates a small number so we need to move the decimal point to the left.

Do not write the power of 10 anymore.

Solution:

Now, let us convert 3.643 x 10^-1 in standard form.

The exponent is negative 1 so we will move the decimal point to the left once.

3.643 = 0.3643

Answer:

Step-by-step explanation:

It takes Lucas 3 hours to cycle from his home to his friend’s village:  

3 hours • (a certain speed) = distance in miles  

If he travels 5mph slower, it will take him 1.5 hours longer:

4.5 hours • (the same speed - 5mph) = the same distance in miles

 4.5 • (x - 5) = 3x

4.5x - 22.5 = 3x

1.5x = 22.5

x = 15mph  

3hours • 15mph = 45 miles

If he's been at the gym for 6 months, and he is charged $20 each month, then he has paid $120 dollars, not counting his membership fee. His total bill is $150.

150-120= $30

His membership fee was $30.

Hope this helps!

Mark Brainliest plz!

x is the number of months and y is the membership fee

[tex]cost = 20x + y[/tex]

[tex]150 = 20(6) + y[/tex]

[tex]150 = 120 + y[/tex]

[tex]150 - 120 = 120 - 120 + y[/tex]

[tex]30 = y[/tex]

The membership fee was $30.

Answer: The acute angle ∠YXZ = 24.3°.

Step-by-step explanation:

If in triangle ABC, C is the angle included between sides a and b then

Area of triangle = [tex]\dfrac12a\cdot b\cdot sin C[/tex]

here, XZ = 21.5cm and XY = 13.5cm are sides that includes acute angle ∠YXZ..

Area of a triangle = 59.7cm²

then, as per given, we have

[tex]59.7=\dfrac12(21.5)(13.5)\ \sin X\\\\\Rightarrow\ 59.7=145.125\ \sin X\\\\\Rightarrow\ \sin X = \dfrac{59.7}{145.125}\\\\\Rightarrow\ \sin X =0.41137\\\\\Rightarrow\ X = \sin ^{-1}(0.41137)\approx24.3^{\circ}[/tex]

Hence, the acute angle ∠YXZ = 24.3°.

658

Step-by-step explanation:

4+654=658.........

Answer:

658

Step-by-step explanation:

First solve 2x2, which is equal to 4.

Then solve 6 x 109 which is equal to 654.

Now add 4 to 654, and you'll get 658

Percentage of yellow leaves on a tree during Autumn = 40%

Percentage of green leaves on a tree during Autumn = 24%

Percentage of half yellow leaves on the tree during Autumn :

[tex] = \tt100 - 40 + 24[/tex]

[tex] = \tt 100 - 64[/tex]

[tex] = \tt 36 \%[/tex]Thus, the percentage of half yellow leaves on the tree during Autumn = 36%

Number of half yellow leaves on the tree = 36%

Let the total number of leaves on the tree be x.

Which means :

[tex] = \tt36 \% \: of \: x = 72[/tex]

[tex] = \tt \frac{36}{100} \times x = 72[/tex]

[tex] = \tt \frac{36 \times x}{100} = 72[/tex]

[tex] = \tt \frac{36x}{100} = 72[/tex]

[tex] = \tt 36x = 72 \times 100[/tex]

[tex] = \tt36x = 7200[/tex]

[tex] = \tt x = \frac{7200}{36} [/tex]

[tex] \color{plum} = \tt \: x = 200[/tex]

Thus, total number of leaves on the tree = 200

Number of yellow leaves on the tree :

[tex] = \tt40 \% \: \: of \: \: 200[/tex]

[tex] = \tt \frac{40}{100} \times 200[/tex]

[tex] = \tt \frac{40 \times 200}{100} [/tex]

[tex] = \tt \frac{8000}{100} [/tex]

[tex] \color{plum} \tt = 80 \: yellow \: \: leaves[/tex]

Thus, total number of yellow leaves on the tree = 80

Number of green trees on the tree :

[tex] = \tt24 \% \: \: of \: \: 200[/tex]

[tex] = \tt \frac{24}{100} \times 200 [/tex]

[tex] = \tt \frac{24 \times 200}{100} [/tex]

[tex] = \tt \frac{4800}{100} [/tex]

[tex] \color{plum} = \tt 48 \: green \: \: leaves[/tex]

Thus, the total number of green leaves on the tree = 48

Since the sum of all types of leaves form 200[80+48+72=200], we can conclude that we have found out the correct number of each type of leaf.

▪︎Therefore, the total number of leaves on the tree = 200

The number of leaves is on the tree is 200.

Given that,

Now as per the above explanation:

= 100 - 40 + 24

= 100 - 64

= 36

Here we assume the number of leaves on the tree be x

So,

36% of x = 72

x = 200

Therefore we can conclude that the number of leaves is on the tree is 200.
