Answer:

it's a)25

Step-by-step explanation:

angle MHL and JHN+NHK should be the same, they both are 95 degrees

Answer:

45°

Step-by-step explanation:

first of all find X

(3x+20) - (x+25) =x + 20

3x+20-x-25=x+20

3x-x+20-25=x+20

2x-5=x+20

collect like terms

2x-x=20+5

x=25°

recall JHN= (x+20)°

x=25

JHN=((25)+20)°

JHN=(25+20)°

JHN=45°

Okay...the recipe is...

Doughnut muffins

Yields: 36 muffins

5 1/4 cups of flour

1 cup oil

4 1/2 teaspoons baking powder

2 1/4 cups sugar

1 1/2 teaspoons salt

3 eggs

2 1/4 cups milk

3/4 teaspoon cinnamon

Alright, it looks as though what you need to do here first is to turn everything into improper fractions. This would result in:

21/4 cups of flour

1/1 cup oil

9/2 teaspoons baking powder

9/4 cups sugar

3/2 teaspoons salt

3/1 eggs

9/4 cups milk

3/4 teaspoon cinnamon

Then, divide everything by three...

7/4 cups of flour

1/3 cup oil

3/2 teaspoons baking powder

3/4 cups sugar

1/2 teaspoons salt

1/1 egg

3/4 cups milk

1/4 teaspoon cinnamon

...and simplify.

1 3/4 cups of flour

1/3 cup oil

1 1/2 teaspoons baking powder

3/4 cups sugar

1/2 teaspoons salt

1 egg

3/4 cups milk

1/4 teaspoon cinnamon

There you go!

Answer:

The total surface area of the prism is 620 cm²

Step-by-step explanation:

The total area of the prism = lateral area + 2 (area of the cross-section)

The lateral area = perimeter of the cross-section × height

∵ The cross-section of the prism is an isosceles triangle

∵ The sides of the triangle are 13 cm, 13 cm, 24 cm

∵ The perimeter of the triangle is the sum of its sides

∴ The perimeter = 13 + 13 + 24 = 50 cm

∴ The perimeter of the cross-section = 50 cm

∵ The height of the prism is 10 cm

→ Use the rule of the lateral area above to find it

∴ The lateral area of the prism = 50 × 10 = 500 cm²

∵ The area of the triangle = [tex]\frac{1}{2}[/tex] × base × height

∵ The base of the triangle = 24 cm

∵ The height of the triangle = 5 cm

∴ The area of the triangle =  [tex]\frac{1}{2}[/tex] × 24 × 5 = 60 cm²

∴ The area of the cross-section = 60 cm²

→ Substitute the lateral area and the area of the cross-section in the rule

  of the total surface area above

∵ The surface area = 500 + 2(60)

∴ The surface area = 500 + 120

∴ The surface area = 620 cm²

∴ The total surface area of the prism is 620 cm²

Answer:

(1)

Step-by-step explanation:

Given

[tex]\frac{2x}{a}[/tex] + b = c ( subtract b from both sides )

[tex]\frac{2x}{a}[/tex] = c - b ( multiply both sides by a to clear the fraction )

2x = a(c - b) ← distribute

2x = ac - ab ( divide both sides by 2 )

x = [tex]\frac{ac-ab}{2}[/tex] → (1)

Answer:

20cm

Step-by-step explanation:

Answer:

n = 15

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

Here b = n + 1 and h = n + 1 - 5 = n - 4 , then

[tex]\frac{1}{2}[/tex](n + 1)(n - 4) = 88 ( multiply both sides by 2 to clear the fraction )

(n + 1)(n - 4) = 176 ← expand the left side using FOIL

n² - 3n - 4 = 176 ( subtract 176 from both sides )

n² - 3n - 180 = 0 ← in standard form

(n - 15)(n + 12) = 0 ← in factored form

Equate each factor to zero and solve for n

n - 15 = 0 ⇒ n = 15

n + 12 = 0 ⇒ n = - 12

However, n > 0 , thus value of n = 15

Answer:

A=-28 B=-48 C=45

Step-by-step explanation:

-(7x4)= -28 so your first step is multiply the positive and the negative equals a negative (+)x(-)=(-) second is to multiply the numbers

-(6)x8= -28 same steps for the first

(-5)x(9) convert it to 5x9=45

Answer:

9 hours

Step-by-step explanation:

For this problem, we simply need to rewrite the goal length, 3/5 miles, into our ratio of time length equivalence, 1 hour per 1/15 miles.  To do this we find the common denominator to be 15 and rewrite it as so:

3/5

= 3*3 / 5 * 3

= 9 / 15

And since it takes 1 hour per 1/15 mile of road, we can perform the division to find the amount of time:

9/15 / 1/15

= 9/15 * 15/1

= ( 9 * 15 ) / ( 15 * 1 )

= 9 / 1

= 9

Hence, it will take the crew 9 hours to repave the road.

Cheers.

Answer:

A and C

Step-by-step explanation:

Nadine and Trevor both conducted an experiment but Nadine conducted with four possible outcomes and Trevor doubled the trials, therefore, Trevor will have more experimental outcomes than Nadine because he doubled the trials. Moreover, Trevor's experimental probability is more likely closer to theoretical probability than Nadine's, therefore option 'A' and 'C' are correct.

Answer:  

Trevor has more experimental outcomes than Nadine.  

Trevor’s experimental probability is more likely closer to the theoretical probability than Nadine’s.

Answer: B. -4 < y < -1

Step-by-step explanation:

1. Subtract 2 from all three sides to isolate the variable in the center of the inequality

5 < 2 - 3y < 14

3 < -3y < 12

2. Divide each of the three sides by -3 to get y by itself, as each of the answers have y as independent.

3 < -3y < 12

-1, y, -4

3. Rearrange

-4 < y < -1 (b)

Answer:

$45

Step-by-step explanation:

sum the parts of the ratio, 3 + 5 = 8 parts

Divide the amount by 8 to find the value of one part of the ratio.

$120 ÷ 8 = $15 ← value of 1 part of the ratio, thus

3 parts = 3 × $15 = $45 ← amount David received

Answer:

$45

Step-by-step explanation:

ratio is 3:5

David gets 3x, Jack gets 5x

So, 3x+5x=120

8x=120

x=15

David got 3x = 3*15 = $45

Answer:

0

Step-by-step explanation:

A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).

Answer:

0

Step-by-step explanation:

Undefined slopes are vertical, this is horizontal

Answer:

x = 8

Step-by-step explanation:

The attached figure shows the angle pair representation.

Here, two lines are cut by a transversal. It means the corresponding angles are equal i.e.

37 = 6x-11

37+11 = 6x

6x = 48

x = 8

Hence, the value of x is 8.

B

Step-by-step explanation:

[tex]P=2L+2W[/tex]

[tex]P-2L=2W[/tex] (Subtract 2L from both sides of the equation)

[tex]2W=P-2L[/tex] (Symmetric Property of Equality)

[tex]W=\frac{P-2L}{2}[/tex] (Divide both sides of the equation by 2)

[tex]W=\frac{P}{2} -\frac{2L}{2}[/tex] ("Split" the fractions)

[tex]W=\frac{1}{2}P-L[/tex] (Simplify)

Answer:

-7/8 is greater

Step-by-step explanation:

-4/5=-0.8

-7/8=-0.875

To find the greater fraction, we can use the butterfly method.

[tex](-\frac{4}{5} )(- \frac{7}{8} )[/tex]

[tex]-\frac{4\times8}{5\times7}=\frac{32}{35}[/tex]

Therefore, [tex]-\frac{4}{5}[/tex] is greater than [tex]-\frac{7}{8}[/tex].

Answer:

The greatest number of flowers that could be in a bouquet is 9 flowers

Step-by-step explanation:

We solve the above question using Greatest Common Factor method. We find the factors of 27, 9 and 18. The greatest factor common to the 3 number is our answer.

The factors of 9 are: 1, 3, 9

The factors of 18 are: 1, 2, 3, 6, 9, 18

The factors of 27 are: 1, 3, 9, 27

Then the greatest common factor is 9.

The greatest number of flowers that could be in a bouquet is 9 flowers
