Step-by-step explanation:

Use the method of TOA CAH SOH.

[tex]tan(51.3) = \frac{opp}{adj} \\ \tan(51.3) = \frac{u}{4} \\ u = 4 \tan(51.3) [/tex]

[tex] cos(51.3) = \frac{adj}{hypo} \\ \cos(51.3) = \frac{4}{v} \\ v \cos(51.3) = 4 \\ v = \frac{4}{ \cos(51.3) } [/tex]

Perimeter of triangle = Sum of all sides =

Answer:

QR = 4.6 ft

Step-by-step explanation:

By applying tangent rule in the given triangle PQR,

tan(62°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

             = [tex]\frac{8.6}{QR}[/tex]

QR = [tex]\frac{8.6}{\text{tan}(62)}[/tex]

QR = 4.573

QR ≈ 4.6 ft

Answer: 2/21

Step-by-step explanation:

5[5y -6] = 4[y -7]

We first need to open the bracket to be able to solve the question

25y - 30 = 4y - 28

Collect like terms

25y - 4y = -28 + 30

21y = 2.

y = 2/21

Therefore, the value for y is 2/21.

Answer:

8 2/8 kg or 8 1/4 kg

Step-by-step explanation:

Multiply 2/3 by 12 3/8 to find 2/3 of Kurt's last year pumpkin

The fraction 2/3 of 12 3/8 is 8 1/4 thus the mass of the pumpkin Kurt grew this year is 8 1/4.

It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.

The value that appears above the horizontal line is referred to as the numerator.

Given that,

Mass of pumpkin last year = 12 3/8

It's grown by 2/3 factor this year.

2/3 of 12 3/8 → 2/3(12 + 3/8)

⇒ 8 + 2/8

⇒ 8 + 1/4 = 8 1/4

Hence "The fraction 2/3 of 12 3/8 is 8 1/4 thus the mass of the pumpkin Kurt grew this year is 8 1/4".

Given:

Perimeter of a rectangular paper = 22 inches.

Area of the rectangular paper = 28 square inches.

To find:

The dimensions of the rectangular paper.

Solution:

Let l be the length and w be the width of the rectangular paper.

Perimeter of a rectangle is:

[tex]P=2(l+w)[/tex]

Perimeter of a rectangular paper is 22 inches.

[tex]2(l+w)=22[/tex]

[tex]l+w=\dfrac{22}{2}[/tex]

[tex]l=11-w[/tex]                      ...(i)

Area of a rectangle is:

[tex]A=lw[/tex]

Area of the rectangular paper is 28 square inches.

[tex]28=lw[/tex]

Using (i), we get

[tex]28=(11-w)w[/tex]

[tex]28=11w-w^2[/tex]

[tex]w^2-11w+28=0[/tex]

Splitting the middle term, we get

[tex]w^2-7w-4w+28=0[/tex]

[tex]w(w-7)-4(w-7)=0[/tex]

[tex](w-7)(w-4)=0[/tex]

Using zero product property, we get

[tex](w-7)=0\text{ and }(w-4)=0[/tex]

[tex]w=7\text{ and }w=4[/tex]

If [tex]w=7[/tex], then by using (i)

[tex]l=11-7[/tex]

[tex]l=4[/tex]

If [tex]w=4[/tex], then by using (i)

[tex]l=11-4[/tex]

[tex]l=7[/tex]

Therefore, the dimensions of the paper are either [tex]7\times 4[/tex] or [tex]4\times 7[/tex].

Answer:

Step-by-step explanation:Because many objects are not regularly shaped their volume cannot be determined using a volume formula. The volume of these objects can be found by water displacement. A volume of water sufficient to cover the object is placed in a graduated cylinder and the volume read. The object is added to the cylinder and the volume read again. The difference between the two volumes is the volume of the object. This method is demonstrated using the same battery used above.

Answer and Step-by-step explanation:

f(n) = 45 - 4(n - 1)

This is the explicit formula for the sequence.

45 is the initial amount, which is why it is by itself.

The change in the sequence is take away 4, so this becomes a negative 4, which is then multiplied by (n - 1), where n is the term in the sequence.

3. 3 x 0.4 = 1.2

Step-by-step explanation: Hope this helps :)

Answer:

see below

Step-by-step explanation:

whenever there is negative number being squared, you need to add the brackets so that you inside the - 1 in front of the number

so this step is wrong

[tex] \sqrt{ - 9 { }^{2} - 4(1)(20) } [/tex]

the -9 ² , you must include the brackets to include the -1 in front of the 9

so it should be

[tex] \sqrt{( - 9) {}^{2} - 4(1)(20) } [/tex]

so you will get = 1

and then you continue with other parts of the formula and you will get real solutions
