Step-by-step explanation: The price of3.8 pounds of almonds=$39.90 thus we can write Hence the price of almonds is $10.50 per pounds.

AWNSERS:$10.50

Answer:

Step-by-step explanation: 39.90 x 3.8 = 151.62

Answer:

-10%

Step-by-step explanation:

precent change = 135 - 150

(divide both sides by 150)

precent change = -0.1

(multiply both sides by 100 so change to precent)

precent change = -10%

Answer:

10%

Answer:

x=-10

Step-by-step explanation:

[tex]2(x+3)=x-4[/tex]

distributive property on left side:

[tex]2x+6=x-4[/tex]

subtract x from both sides

[tex]x+6=-4[/tex]

subtract 6 from both sides

[tex]x=-10[/tex]

Answer:

-10

Step-by-step explanation:

2(x+3)=x-4

Distribute (multiply everything in parenthesis):

2x+6=x-4

Subtract -x from both sides

X+6=-4

Subtract 6 from from both sides:

X=-10

Answer:

1065. 1 * 10^3

Step-by-step explanation:

Answer:

Initial value is (0 , 24) or just y = 24

Step-by-step explanation:

Initial value of a linear function is the y intercept

y = -3x + 24

x = 0, y = 24

Answer:

m∠B = 63°

AB = 26.4

AC = 23.6

Step-by-step explanation:

m∠B = 90 - 27 = 63°

Sin 27 = 12/AB

AB (sin 27) = 12

AB = 12/sin 27 = 26.4

Tan 27 = 12/AC

AC (tan 27) = 12

AC = 12/tan 27 = 23.6

Answer: The answer is B

Answer:

The answer is 80

Step-by-step explanation:

78 is closer to 80

Answer:

the answer is 80

Step-by-step explanation:

it will be 80 because 78 is closest to 8

Answer:

-56

Step-by-step explanation:

That is because the 56 is below sea level, not above it, so it would be negative 56

Hope that helps!

-56ft

Since it is BELOW sea level it would be considered a negative number. If it were ABOVE sea level then it would be a positive number. Another way to think about this:

Above Sea Level = +

Below Sea Level = -

Hope this helps and have a nice day.

Answer:

1.03 inches

Step-by-step explanation:

Volume of a come = 1/3πr²h

If the height of a right cone is 3 inches shorter than the radius, then;

h = r - 3

Substitute

V = 1/3πr²(r-3)

Given that V = 17in^3

17 = 1/3πr²(r-3)

17*3 = 3.14r²(r-3)

51/3.14 = r²(r-3)

16.242 = r²(r-3)

r² = 16.242

r = √16.242

r = 4.03

Since h = r - 3

h = 4.03 - 3

h = 1.03 inches

hence the height is 1.03 inches

Answer:

9 percent

Step-by-step explanation:

Answer:

3%

Step-by-step explanation:

1st Method: Increase Formula = (Last value-first value)/(first value)

Increase = (309-300)/300 = 9/300 = 3/100

= 0.03 or 3%

2nd Method: 309/300 = 103/100 = 1.03 (increase over 1 is 0.03 = 3%

Answer:

65 cm

Step-by-step explanation:

Hey There!

So the congruency statement ABC = TUV

states that side AB = side TU side BC  = side UV and side CA = side VT

The given side lengths are BC and UV which are congruent to each other so we set up an equation to solve for x

7x+2=6x+11

step 1 subtract 2 from each side

2-2 cancels out

11-2=9

Now we have

7x=6x+9

step 2

subtract 6x from each side

7x-6x=x

6x-6x cancels out

now we have 9=x so x=9

Now we just plug in 9 to x in (6x+11)

to find the length of the given side length

6x9=54

54+11=65

Because side VU and side BC are congruent they both equal 65 cm

So we can conclude that the length of the given sides is 65 cm

Answer:

1169 in^2 Approx

Step-by-step explanation:

Given data

We know that the shape of the pencil is cylindrical

Hence the dimension is

Diameter= 12in

Radius= 12/2= 6in

Height= 25in

The surface area of a cylinder is given as

T.S.A.=2πrh+2πr^2

Substitute

T.S.A.=2*3.142*6*25+2*3.142*6^2

T.S.A.=942.6+226.224

T.S.A=1168.824

Hence the area is 1169 in^2 Approx

Answer:jghgghfgfhgfhghfj

Step-by-step explanation:

Answer: k = 16

Step-by-step explanation:

The equation is written in the form:

y = ax^2 + bx + c

y = -x^2 - 6x + 7

y = a(x - h)^2 + k where (h, k) is the vertex

a = -1 (from the original equation)

h = -b/2a (this is the equation for the line of symmetry or the x-value of the vertex)

h = -(-6)/2(-1) = 6/-2 = -3

when x = -3, y = ?

y = -(-3)^2 - 6(-3) + 7

y = -(9) + 18 + 7

y = -9 + 18 + 7

y = 16

(-3, 16) is the vertex

Since k is the y-value of the vertex, k = 16

I'll just take it a step further and write the whole equation:

Substitute all the values we found

-1(x +3)^2 + 16

-(x + 3)^2 + 16
