Step-by-step explanation:

Answer:

11 and 23

Step-by-step explanation:

If she uses a scale factor that is greater than one, then we know that the answer has to be greater than 10 units, since the triangle is going to be larger.

The only two answers here that are greater than 10 are:

11 and 23

So answer is 11 and 23

Answer:

19.11 square units

Step-by-step explanation:

The fish tank is composed by eight rectangles with base = 0.9 units and height = 2 units; and by a regular octagon at the bottom, which sides are 0.9 units long.

Area of each rectangle = 0.9*2 = 1.9 square units

Area of the regular octagon = 2*(1 + √2)*0.9² = 3.91 square units

Therefore:

Surface area of the fish tank = 8*1.9 + 3.91 = 19.11 square units

Step-by-step explanation:

Answer:

? ≈ 52.3°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin ? = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{19}{24}[/tex] , thus

? = [tex]sin^{-1}[/tex] ([tex]\frac{19}{24}[/tex] ) ≈ 52.3° ( to the nearest tenth )

Answer:

≈ 52.3

Step-by-step explanation:

You are given the opposite and hypotenuse side, leading you to use sin. However, since you're trying to find the angle measurement, you use the inverse of sin: [tex]sin^-1[/tex]

Set it up like this:

[tex]sin^-1(\frac{19}{24}) = ?[/tex]

When you solve, you get:

52.34

Round to the nearest tenth:

52.3

Answer:

1) 25

2) 20

Step-by-step explanation:

1)

Since these are vertical angles, they are congruent. Therefore, 3x=75, and x=25 degrees.

2)

Once again, these are vertical angles.

2+3x=62

3x=60

x=20 degrees

Answer:

[tex](x-5),(2x+3)[/tex]

Step-by-step explanation:

Given: area of a rectangle is [tex]2x^2-7x-15[/tex]

To find: binomials that represent the length and the width of the rectangle

Solution:

A polynomial that consists of two terms is known as binomial.

[tex]2x^2-7x-15=2x^2-10x+3x-15\\=2x(x-5)+3(x-5)\\=(2x+3)(x-5)[/tex]

Also, area of rectangle is length × breadth

So, length × breadth = [tex](2x+3)(x-5)[/tex]

So, length = 2x+3, breadth = x-5 or length = x-5, breadth = 2x+3

Answer:

100 miles

Step-by-step explanation:

Using the red line

Go on the x axis to the 5

Then go straight up til you meet the red line

Go to the left and read the y axis

100 miles

Answer:

B) 100

Step-by-step explanation:

Just follow the line. x = 5 so y = 100

A trick a teach of mine once told me was to imagine the grid as an airplane taking off. It has to start from the x and go up to the y so it can fly. If it started from the y and then went down to the x, it would crash.

Hope this helps!!

Answer:

a) x + y ≤ 16

y/x ≥ 3/5

12*x + 4*y ≥ 72

b) see picture attached

c) 5 pizza makers and 3 cashiers should be hired.

Step-by-step explanation:

a) Let's define:

x: amount of pizza maker

y: amount of cashier

From conditions in the question:

x + y ≤ 16

y/x ≥ 3/5

12*x + 4*y ≥ 72

b) In the picture attached, the feasible region (also called solution region) is shown.

c) We want to minimize:

10*x + 6*y

subject to the previous restrictions.

It is known that the optimum solution is on the vertex of the feasible region (it is a linear system). Evaluating cost function at each point, we get:

10*1 + 6*15 = 100

10*5 + 6*3 = 68

10*10 + 6*6 = 136

Then, 5 pizza makers and 3 cashiers should be hired.

Answer:

the slopes of DE and EF are opposite reciprocals make the triangle Δ DEF a right triangle.

Step-by-step explanation:

The characteristics will prove that Δ DEF is a right isosceles triangle is the lengths of DE and EF are congruent, and their slopes are opposite reciprocals.

Now, the equal sides of DE = EF make the triangle Δ DEF an isosceles triangle and the slopes of two perpendicular lines are always the opposite reciprocals.

So the correct answer would be: The lengths of DE and EF are congruent, and their slopes are opposite reciprocals.

A right-angle triangle with two equal sides forming that right angle must be a right isosceles triangle.

What is a right isosceles triangle?

A triangle that has  a right-angle and two equal sides is called a right-isosceles triangle.

Characteristics will prove that ΔDEF is a right isosceles triangle are as follows:

1. A right isosceles triangle must have a right angle.

2. Two sides of it must be equal. Obviously, the hypotenuse is the biggest side of the triangle. Apart from the hypotenuse, other two sides must be same. It will make their slope with the hypotenuse equal. Hence, the triangle will be also be isosceles.

Answer:

B

Step-by-step explanation:

you add 3 plus 2 which gives you 5

then it said one red marble which is 2/5 then it said another one which is 1/4

2/5 times 1/4 equals 1/10

As you can see, the cube and the cylinder are the same height and width. But, if you use their 2d counterparts, a square and a circle, a circle always takes up 78.5% of the squares area. Knowing this, we can take this knowledge and see that the cube will have a greater volume.

Answer:

Your answer is B.), 26 in.²

Step-by-step explanation:

So, what you do is you have to split it into two different shapes, find the areas of those, and then "put them back together" (add them together).

So, what I did is I made the whole top part one shape and then the bottom part. Here are the dimensions:

Top Part: 2 in. × 9 in.

Bottom Part: 4 in. × 2 in.

Now, you multiply and add them.

Top Part:

[tex]2*9=18[/tex]

Bottom Part:

[tex]4*2=8[/tex]

Add:

[tex]18+8=26in.^{2}[/tex]

Since it's a 2-dimensional figure, do not forget that when you label, you have to put a "2," as in "squared," like it's an exponent, but know that it is not an exponent. It's just so that people know, when looking at it, that it's the area of a 2-dimensional figure.

Answer:

25. x = 17°

26. x = 50°

Step-by-step explanation:

25. There is a straight line which means :

108 +4x = 180

solving the obtained equation

108+4x = 180

4x = 180 - 108

4x = 72

x = 72/4

x = 17°

26. Again we can see that the angles in which 101 and x + 29 exists is a straight line . which means :

101 + x + 29 = 180

101 + 29 + x = 180

130 + x = 180

x = 180 - 130

x = 50°

So the answer of question no. 25 is 18 degree.

The answer of question no 26 is 50 degree.

The first 4 guests can arrive at party in 1365 ways if 15 guest have been invited

Step-by-step explanation:

Total number of guests invited = 15

We are supposed to find in how many ways can the first 4 guest arrive at a party if 15 guest have been invited

We will use combination

Formula :[tex]^nC_r=\frac{n!}{r!(n-r)!}[/tex]

Substitute n = 15 and r = 4

So,Total no. of ways = [tex]\frac{15!}{4!(15-4)!}=1365[/tex]

Hence the first 4 guests can arrive at party in 1365 ways if 15 guest have been invited

Answer:

Step-by-step explanation:

The first 4 guests can arrive in 32,760 ways.
