Question is: Mom can make 10 brownies from a 12-ounce package. The brownie mix is also sold in 1 and a half-pound bags. How many bags would be needed to make  120 brownies?

Step-by-step explanation:

As mentioned in question,

10 brownies made from = 12 ounce package

120 brownies will be made from = 10 * 12 packages

now 12 packages will have ounces = 12 * 12 = 144 ounces

We also know that packages are one and a half pounds

Applying conversion factor = 1.5 pound = 24 ounces

Now we can find answer: 144 ounces total requires / 24 ounces

Answer = 6 bags

6 bags of 1.5 pounds will be required for 120 brownies.

Answer:

169 [tex]cm^2[/tex]

Step-by-step explanation:

The surface area is the two-dimensional distance around a figure. In essence, if one was going to wrap the figure in paper, the surface area would be the amount of paper one would need. To find the surface area, one would have to find the area of each individual face, and add up the values.

(7) * (5) = (35)

(9) * (5) = (45)

(7) * (5) = (35)

([tex]\frac{1}{2}[/tex]) * (6) * (9) = (27)

([tex]\frac{1}{2}[/tex]) * (6) * (9) = (27)

Add up all of the values:

(35) + (45) + (35) + (27) + (27) = 169

James has dimes and quarters saved up in his change jar. He has a total of 162 coins totaling $31.20 what is the total amount james has in quarters?

a. $10.00

b. $6.20

c.$15.50

d.$25.00

Answer:

d.$25.00

Step-by-step explanation:

With the information provided, you can write the following equations given that dimes are equal to 0.10 and quarters to 0.25 to determine the number of dimes and quarters that James has:

x+y=162 (1)

0.10x+0.25y=31.20 (2), where:

x is the number of dimes

y is the number of quarters

First, you can solve for x in (1):

x=162-y (3)

Then, you have to replace (3) in (2) and solve for y:

0.10(162-y)+0.25y=31.20

16.2-0.10y+0.25y=31.20

0.15y=31.20-16.2

0.15y=15

y=15/0.15

y=100

Finally, you have to replace the value of y in (3) to find x:

x=162-100

x=62

Now, you know that James has 100 quarters and you can multiply this number for the value of a quarter to find the amount James has in quarters:

100*0.25=25

According to this, the answer is that James has $25 in quarters.

Answer:

16 years

Step-by-step explanation:

Given data

For the first tree

let the expression for the height be

y=4+x--------------1

where y= the total height

          4= the initial height

          x= the number of years

For the second tree, the expression is

y=12+0.5x-------------2

Equate 1 and 2

4+x=12+0.5x

x-0.5x=12-4

0.5x= 8

x= 8/0.5

x=16

Hence it will take 16 years for both trees to have the same height

Answer:

25 is the answer

for proof see the pic

first divide it by 11 then and when you get the numerator as 100 and denominator as 4 divide it by 2

So as to get numerator as 50 and denominator as 2 .

Later, Divide it by 2 and hence, your answer is 25.....;)

The value of x in the triangle is 35 degrees, option A is correct.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Let us find the interior angles

The sum of interior and exterior angle is 180

95+x=180

x=85

We know that the sum of three angles is 180 degrees by angle sum property

60+85+x=180

145+x=180

Subtract 145 from both sides

x=180-145

x=35 degree

Hence, the value of x in the triangle is 35 degrees, option A is correct.

Answer:

Area of triangle = 8.9

Area of parallelogram = 53.4 yd² (option A)

Step-by-step explanation:

✔️Area of the triangle = ½*base*height

base = 3 m

height = 5.9 m

Area of triangle = ½*3*5.9

Area of triangle = 8.85 ≈ 8.9 (nearest tenth)

✔️Area of parallelogram = base*height

base = 8.9 yd

height = 6 yd

Area of parallelogram = 8.9*6 = 53.4 yd²

Answer:

of triangle =12base×height

Area of triangle =2x2−11x+15

base =2x−5

Plugging in the given;

2x2−11x+15=12(2x−5)×height

2x2−11x+15=2x−52×height

2x2−11x+151=2x−52×height

2(2x2−11x+15)=(2x−5)×height

4x2−22x+30=(2x−5)×height

4x2−22x+302x−5=height

Resolving the quadratic equation;

(4x2−22x+30)

Simplifying;

4x

Answer:

2x-6

Step-by-step explanation:

height : 2(2x^2-11x+15)/(2x-5)

(4x^2-22x+30)/(2x-5)

Δ/4 = 121 - 120 = 1

x1 = (11+1)/4 = 3

x2 = (11-1)/ 4 = 5/2

4(x-5/2)(x-3)

(4x-10)(x-3)/(2x-5)

2(2x-5)(x-3)/(2x-5)

2x-6

Proof

(2x-6)(2x-5)/2

2(x-3)(2x-5)/2

2x^2-5x-6x+15

2x^2-11x + 15
