its for 7th grade plss help me

Answer:

[tex]Q = 96.4^\circ[/tex]

[tex]R = 58.4[/tex]

[tex]P =25.2[/tex]

Step-by-step explanation:

Given

See attachment for PQR

Required

Solve the triangle

From the attached triangle, all sidea of the triangle are known.

i.e.

[tex]PQ = 6\\QR=3\\PR=7[/tex]

So, we are to solve for [tex]\angle P, Q \& R[/tex]

Using cosine rule:

[tex]a^2 = b^2 + c^2 - 2bcCosA[/tex]

To solve for Q, we have:

[tex]PR^2 = PQ^2 + QR^2 - 2 * PQ * QR Cos(Q)[/tex]

[tex]7^2 = 6^2 + 3^2 - 2 * 6 * 3 * \cos(Q)[/tex]

[tex]49 = 36 + 9 - 36 * \cos(Q)[/tex]

Collect like terms

[tex]49 - 36 - 9 = - 36 * \cos(Q)[/tex]

[tex]4 = - 36 * \cos(Q)[/tex]

Divide both sides by -36

[tex]\cos(Q) = \frac{-4}{36}[/tex]

[tex]\cos(Q) = -0.1111[/tex]

Take arc cos of both sides

[tex]Q = cos^{-1}(0.1111)[/tex]

[tex]Q = 96.4^\circ[/tex]

To solve for R, we make use of sine rule;

[tex]\frac{a}{\sin A} = \frac{b}{\sin B}[/tex]

So, we have:

[tex]\frac{PQ}{\sin R} = \frac{PR}{\sin Q}[/tex]

[tex]\frac{6}{\sin R} = \frac{7}{\sin 96.4}[/tex]

Cross multiply

[tex]\sin R * 7 = 6 * \sin 96.4[/tex]

Solve for sin R

[tex]\sin R = \frac{6 * \sin 96.4}{7}[/tex]

[tex]\sin R = \frac{6 * \0.9938}{7}[/tex]

[tex]\sin R = 0.8518[/tex]

Take arc sin of both sides

[tex]R = sin^{-1}(0.8518)[/tex]

[tex]R = 58.4[/tex]

Solving P:

[tex]P+ Q + R = 180[/tex] --- angles in a triangle

Solve for P

[tex]P =180-Q-R[/tex]

[tex]P =180-96.4-58.4[/tex]

[tex]P =25.2[/tex]

Answer:

son consonantes

guíate por esto.

La rima asonante se caracteriza porque solo coinciden los sonidos vocálicos en la última sílaba de cada verso, mientras que la rima consonante es aquella donde coinciden tanto vocales como consonante.

Answer:

[tex]A_f=470ft[/tex]

[tex]P_f=88ft[/tex]

Step-by-step explanation:

From the question we are told that:

Width of Portrait [tex]w=10inches[/tex]

length of Portrait [tex]l=13inches[/tex]

Frame each [tex]l_W=21/4inch each[/tex]

Generally the equation for area of portrait A is mathematically given by

[tex]A=w*l\\A=10*13\\A=130m^2[/tex]

Generally the equation for Perimeter of portrait is mathematically given by

[tex]P=2(w+l)\\P=2(10+13)\\P=46m[/tex]

Generally the equation for area of portrait  with frame is mathematically given by

[tex]A=w_f*l_f[/tex]

where

w_f=width of portrait with frame

[tex]w_f=2*21/4+w\\w_f=2*21/4+10\\w_f=20.5ft[/tex]

l_f=Length of portrait with frame

[tex]l_f=2*21/4+l\\l_f=2*21/4+13\\l_f=23.5ft[/tex]

Therefore Area of picture with frame

[tex]A_f=w_f*l_f[/tex]

[tex]A_f=20.5*23.5[/tex]

[tex]A_f=470ft[/tex]

Generally the equation for Perimeter of portrait is mathematically given by

[tex]P_f=2(w_f+l_f)\\P_f=2(20.5+23.5)\\P_f=88ft[/tex]

Answer:

area = 228 m^2

Step-by-step explanation:

here's your solution

=> length = 20 m. , width = 12 m

=> Area of rectangle = length*width

=> Area of rectangle = 12*20

=> Area of rectangle = 240 m^2

now we need to find area of traingle

=> base = 4 m. , height = 6 m

=> area of traingle = 1/2*base*height

=> area of traingle = 1/2*4*6

=> area of traingle = 12 m^2

=> now , area of figure = 240 m^2 - 12 m^2

=> 228 m^2

Answer:

Steps:

600 - 480 = 120

100(120/480) = 25

Answer:

increase in percentage = 25%

Step-by-step explanation:

here's your solution

==> Total number of students last year = 480

==> Number of students this year = 600

==> Number of increased students = 600 - 480

= 120 students

==> now , in percentage = (120/480)*100

==> percentage increase = 25%

Answer:

5. B 6A. True 6B. True 6C. False 6D. True

Step-by-step explanation:

Answer:

5/9

Step-by-step explanation:

You have 10 movies in total. You take 1 out of 6 action movies. Now you have 5 action movies left, so that means the probability is 5/9. It's 5/9 because you chose 1 action movie out of 10 movies in total, so that means there are 9 movies in total left.

Hopes this helps and makes sense!

Answer:

3x-2

Step-by-step explanation:

12x-8/4 = 3x-2 is one side length of a square

Answer:

48

Step-by-step explanation:

by parallel laws

132 + x = 180

x = 48

so x must be 48

Answer:

D . 8x - 3

proof

16x - (3 + 8x ) = 8x - 3

16 -3 - 8x = 8x - 3

8x -3 = 8x - 3

Answer: 1/4

Step-by-step explanation:

In a stack of 24, the 2 mediums are odd and even cards in this question. This means that 1/2 the cards are even and 1/2 are odd. To get a even card once is a 1/2 chance, then to get it again is 1/2 x 1/2 chance or 1/4 chance. This is what I think.

Answer:

CB = sqrt62

Step-by-step explanation:

The pythagorean theorem will help with this! First take triangle ACD, AD^2 + CD^2 = AC^2. Plug in, AD^2 + 16 = 25. AD^2  = 9. AD = 3. I'm not exactly sure how to find DB, but I can assume it's double of AD< so 6. We know CD is 4, so  4^2 + 6^2 = CB^2. 16 + 36 = CB^2. CB = sqrt62

Sorry if this isn't exactly right, there's no exact way to find DB.

Step-by-step explanation:

Answer:The mean absolute deviation (MAD) of the number of pages in the 5 books Rori read =24

Step-by-step explanation:

To find the the mean absolute deviation (MAD,we start firt by

Getting  the mean of all values

Mean =120, 106, 94, 100, 180/5  =600/5=120

Next we subtract the mean value  from each value which is called distance

120 -120  = 0

106 -120 = -14

94 -120=  -26

100 -120=-20

180 -120=60

Thirldly, we find the mean of the distances  ignoring the negative signs

0+14+26+20+60 / 5 = 120/5=24

r = 1/15

a branliest from the answer will be appreciated
