Answer:

This is a triangle with 2 equal angles and equal to 60

=> this is an equilateral triangle

=> y = 60

    4x.3 = 54

=> y = 60

    x = 54/12 = 4.5

Step-by-step explanation:

Answer:

Step-by-step explanation:

if two angles are 60 degrees, the third one is also 60 degrees

that means all the sides are equal

if one side is 4x

4x+4x+4x=54

12x=54

x=4.5

Answer:

100 customers

Step-by-step explanation:

The computation of the number of dell customers would be in the spring is shown below:

Given that

In winter season

The ratio of daily customers to weekly customers  = 1:5.

In Spring season :

The ratio of daily customers to weekly customers = 4:2.

And, the Number of the weekly customer in the winter is 125

So if we can see that the weekly customers would be 5 times of daily customers  

So, the daily customers in winter is

= 125 ÷ 5

= 25 customers

Now in the spring it would be

= 25 × 4

= 100 customers

Answer:

C: 191.

Step-by-step explanation:

The total area of this is a little less than 15 x (3+4+10) = 15 x 17 = 255.

So then we subtract that by 36, which is the rectangle that is missing from the shape. So 255-36 = 219.

So now we have to guess. The triangle seems a little small, so it has to be the largest option, which is C: 191.

Answer:

  (b)  30

Step-by-step explanation:

The standard form of a quadratic is ...

  y = ax^2 +bx +c

For such a function, the axis of symmetry is ...

  x = -b/(2a)

Your quadratic function has a=-5, b=+300, so the axis of symmetry is ...

  x = -300/(2(-5) = 30

The peak of the curve is on the axis of symmetry. So, profit is maximized when 30 items are produced.

Of course, a graphing calculator can display the maximum of the function easily.

Answer:

16 girls in the class

14 boys in the class

Step-by-step explanation:

Because of the ratio of 7:8, I added 7+8.

7+8= 15

30 (the number of students in the class) divided by 15 (the sum of the ratio)

30/15= 2

I then multiplied 8 from the "girls" part of the ratio by 2 (the quotient of 30/15) and got 16. Then I subtracted 16 from 30 and got 14, which s the number of boys in the class.

Hope this helps!

Answer:

x = -9

Step-by-step explanation:

-2x + 6 + 4x = -12

-2x + 4x = -12 - 6

2x = -18 -----Divide -18 by 2

x = -9

Answer:

x < - 3

Step-by-step explanation:

Given

15 < - 5x

Divide both sides by - 5, reversing the symbol as a result of dividing by a negative quantity

- 3 > x , that is

x < - 3

The simplified expression is x < -3.

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is the condition of being unequal. It is used most often to compare two numbers on the number line by their size.

For the given situation,

The expression is 15 < -5x

⇒ [tex]15 < -5 x[/tex]

Divide both sides by -5,

⇒ [tex]\frac{15}{-5} < \frac{-5}{-5} x[/tex]

When we divide an inequality with negative number, we need to change the sign,

⇒ [tex]-3 > x[/tex]

⇒ [tex]x < -3[/tex]

Hence we can conclude that the simplified expression is x < -3.

Answer:

Let Ishaan's age be x. Then, Christopher's age is x-20. These are their current ages.

14 years ago,

x-14 = 3(x-20-14) (we need to subtract 14 from both of their ages')

x - 14 = 3(x - 34)

x - 14 = 3x - 102

2x = 88

x = 44

Ishaan is 44 years old now.

Answer:

Christopher is 44 and ishaan is 24

Step-by-step explanation:

So im guessing this question is asking how old they are now

if christopher is 20 years older he will always be 20 years older

so we need to find how old he was 14 years ago

he was 1/3rd the age meaning that 20 is 2/3s so that means that ishaan was 10 years old

then add 14 years and he is 24

Answer:  The original rectangle was 15 inches by 6 inches

=============================================================

Explanation:

Let's make the length longer than the width, so L = W+9 since we're told that one side is 9 inches longer than another.

The area of this rectangle is

Area = length*width

A = L*W

Through substitution, we can replace L with W+9

A = (W+9)W

A = W^2 + 9W

We'll come back to this later.

--------------

Now let's decrease the longer side L by 5 inches to get L-5. At the same time, we'll increase the shorter side W by 3 to get W+3.

The new rectangle is (L-5) inches by (W+3) inches which leads to the area of...

A = (length)*(width)

A = (L-5)*(W+3)

A = (W+9-5)*(W+3) .... L replaced with W+9

A = (W+4)(W+3)

A = W^2 + 3W + 4W + 12 .... FOIL rule

A = W^2 + 7W + 12

--------------

We found these two area expressions

We're told that the two areas (of the original and new rectangle) are equal to one another. Set them equal to each other and solve for W

W^2 + 9W = W^2 + 7W + 12

9W = 7W + 12 ............ subtracted W^2 from both sides

9W-7W = 12

2W = 12

W = 12/2

W = 6

The original width is 6 inches

L = W+9 = 6+9 = 15

The original length is 15 inches

The original area is L*W = 15*6 = 90 square inches

The new rectangle has side lengths of (L-5) = (15-5) = 10 inches and (W+3) = (6+3) = 9 inches. Then note how the area of this new rectangle is 10*9 = 90 square inches to match the other area. This helps confirm we have the correct answer.

Answer: it’s D

Step-by-step explanation:

The correct postulate or theorem that applies is,

D. Cannot be determined

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Since, We have to given that,

Side AG = 10 units

And, ∠AGT ≅ ∠AGB.

Thus, options A and B are discarded.

Now, As for the SAS criteria, we need two sides to be congruent and their included angles to be congruent.

But, as no other information is given, we cannot determine whether the given triangles are congruent or not.

Hence, option D is correct.

Statement 4 is incorrect.

Adoption cost in the given problem is the money spent in maintenance, feeding, and other expenses in order to adopt a pet.

"Adoption costs more money than buying a pet" is an incorrect statement because if we extract the conclusion combinedly from statements 2 and 3, it is clear that adoption cost is in the range of $50 and $500 in the case of a shelter animal while an animal from a pet store typically costs at least $1,000.

"Pet stores are more expensive than breeders", this is an incorrect statement because in the third paragraph it is mentioned that "an animal from a pet store typically costs at least $1,000. Breeders are even more expensive."

"It is more expensive to buy a pet than it is to adopt" is a correct statement because in the fourth paragraph it is mentioned that "adopting pets from shelters is the logical choice because shelter animals are less expensive than those bought from pet stores or breeders."

"Cats are more expensive than dogs" is an incorrect statement because in the second paragraph it s mentioned, "adopting a dog or a cat from a shelter usually costs between $50 and $500." There has not been discussed anything about the individual adoption costs for each.

Therefore, Statement 1 is incorrect.

Statement 2 is incorrect.

Statement 3 is correct.

Statement 4 is incorrect.

Step-by-step explanation:

-4x + 7 ≥ 27

-4x ≥ 20

-x ≥ 5

Whenever you multiply or divide by a negative number in an inequality, flip the sign:

x ≤ -5

x/1 - 9 < -10

x - 9 < -10

x < -1

3x - 10 < -25

3x < -15

x < -5

5 (x - 2) > -15

Use Distributive Property:

5x - 10 > -15

5x > -5

x > -1

A) x < -5

So, A) 3x - 10 < -25.

B) x ≤ -5

So, B) -4x + 7 ≥ 27.

C) x < -1

So, C) x/1 - 9 < -10.

D) x > -1

So, D) 5 (x - 2) > -15.
