Answer: 10 pans

Step-by-step explanation:

Step 1:

If the number of biscuits needed= 80

Step 2:

And the number of biscuits on each pan= 8

Step 3:

Then the number of pans needed= 80 ÷ 8

Answer: 80 ÷ 8 = 10pans

Answer:

i love algebra anyways

the ans is in the picture and the steps how got it

(hope it helps can i plz have brainlist it will make my day :D hehe)

Step-by-step explanation:

Answer:

Step-by-step explanation:

(-2x-3)(4x+5) = -(2x+3)(4x+5) = -(8x^2+12x+10x+15) = -8x^2 - 22x - 15

Leading coefficient is -8

Answer:

tan y°

Step-by-step explanation:

by using the Sine Rule (See attached), we can form the equation:

[tex]\frac{r}{sin (y)} = \frac{p}{sin (x)}[/tex]

rearranging this, we get:

[tex]\frac{r}{p} =\frac{sin(y)}{sin(x)}[/tex]   ---------------------eq 1

Recall that all internal angles of a triangle must sum to 180°. we observe that we have a right triangle where one of the angles is 90°. It then follows that the sum of the other two angles must sum to 90°

i.e x + y = 90°

with a little rearranging, we get

x = (90° - y)

Substituting this into eq 1 above, we get:

[tex]\frac{r}{p} =\frac{sin(y)}{sin(90- y)}[/tex]  ---------eq 2

recall that from the trigonometric co-function identities,

sin (90°- y) = cos y

substituting this into eq 2 gives :

[tex]\frac{r}{p} =\frac{sin(y)}{cos(y)} = tan(y)[/tex]   (answer)

Answer:

52 minutes

Step-by-step explanation:

it takes him 13 minutes to complete 5 so if he wants  to do 20 problems  do 20 divided by 5 (4) then do 13 times 4=52

♥ Hey Grey Here! ♥

Answer:

i believe it should be C

Step-by-step explanation:

dont forget to say thanks

brainelist??

Answer:

C

Step-by-step explanation:

Answer:

Step-by-step explanation: It would be A because the factor is the denominator and it would be more units in size, so there are 60,000 inches in 5,000 feet.

Answer

Step-by-ste$6.48- $6.00= $.48

.48÷ 6.0= 0.08

0.08 = 8%

tax rate is 8%

p explanation:

Answer:

3%

Step-by-step explanation:

6.18-6.00 = .18

.18/6.00= .03

.03= 3%

Answer:

c. 80

Step-by-step explanation:

cos x = sin(x-70)

cos x = cos [90-(x-70)]

cos x = cos (90-x +70)

cos x = cos 160 -x

x= 160-x

2x = 160

x =80

Answer:

Answer:

The width of Dana's living room is 16 feet.

Explanation:

Because Dana's living room is rectangular and we are given the length of one side and the length of the diagonal we can use the Pythagorean Theorem to solve this problem.

For a right triangle which the length, width and diagonal make up the Pythagorean Theorem states:

a

2

+

b

2

=

c

2

Let the length of 12 be

a

and because the diagonal is the hypotenuse of the triangle (the side opposite the right angle) we let

c

be 20. Substituting and solving gives:

D is your answer i believe

Step-by-step explanation:

using g(x), -1, which is our change of x will go right. -5 is our change in y, so therefore it goes down. negative means down, positive means up for our change of y. for our change of x, negative goes right, and postive goes left. thats why i think the answer is d

Step-by-step explanation:

If <y=A

In this case 360-25=335

Step-by-step explanation:

x = 49° { being vertically opposite angles }

y = 63° (being alternate angles)

Hope it will help :)

Answer:

C. The y-intercepts of the two functions are opposites.

Step-by-step explanation:

The y-intercept of g(x) is -1 and the y-intercept of h(x) is 1. -1 and 1 are opposites, so the two y-intercepts are also opposites.

Answer:

5x+6

Step-by-step explanation:

x-3+7x+21-3x-12

Answer: Charlotte's 15 and Edgar's 7

Step-by-step explanation:

7*2=14

14+1 = 15

15 + 7 = 22

Answer:

162

Step-by-step explanation:

a=[tex]\frac{a+b}{2} h[/tex]

a=base and the base is 13 ft.

b= also means base which is 23 ft.

h= height which is 9 ft.

so 13+23 is 36

36/2 is 18

and 18 times 9 is 162

sorry for the lengthy answer but i hope this helps :) have a nice day !!
