Answer:

30

Step-by-step explanation:

All of the angles add to 180 degrees for a triangle

x + 2x + 3x = 180

6x = 180

x = 30

The time it would take you to run 3.1 miles given the time it takes you to run a mile is 24 minutes 48 seconds.

Multiplication is a mathematical operation that is used to determine the product of a number. The sign used to represent multiplication is ×.

In order to determine the time, multiply 3.1 miles by 8 minutes

3.1 x 8 = 24.8 =  24 minutes 48 seconds.

Answer:

2 outfits and 7 ties left

Step-by-step explanation:

Answer: my guess is 18 or 4 because you can multiply 2*9 or divide 9/2 which gives you 4.5

You could round it but then it would just be 4 outfits and a half which wouldn’t make sense so it’s best if 4. I really hope if I helped because honestly I was confused too lol have a good day

Answer:

Step-by-step explanation:

Is that Ed genuity?! I used to use it. I had the same problem once!

Expanding the product gives

(2 - 3i) (4 + 3i) = 8 - 12i + 6i - 9i² = (8 + 9) + (6 - 12) i = 17 - 6i

so a = 17.

d) You have a difference of squares:

49y² - 9 = (7y)² - 3²

Recall the identity,

a² - b² = (a - b) (a + b)

So,

49y² - 9 = (7y - 3) (7y + 3)

e) Pull out the common factor 3 from each term:

3x² - 3x - 90 = 3 (x² - x - 30)

Now use the sum-product method. Notice that we can write 30 = 5 • 6, and 5 - 6 = 1, so

3x² - 3x - 90 = 3 (x + 5) (x - 6)

f) Same as in (e), use the sum-product method. Notice that 42 = 7 • 6, and -7 - 6 = -13, so

x² - 13x + 42 = (x - 7) (x - 6)

Step-by-step explanation:

first, find the unit rate. to get the unit rate, we would figure out how many miles he can ride in 1 hour. to get this, divide by 3, to get hours to 1 instead. now divide miles by 3 to get 3 mph. multiply by 4, and you have your answer.

The length of the tent to the nearest foot, from the front to the back is 42 ft. the total amount of space inside the tent is 816.83 cubic feet.

A right triangular prism is a 3-dimensional triangle with two congruent triangular faces and 3 rectangular faces that connect the triangular.

The volume of a right triangular prism = ( height × Base Area)

A. The length of the tent to the nearest foot, from the front to the back

= 15 + 6 + 15+ 6

= 42 ft

B. Given that the tent is in the shape of a triangular prism the volume of the prism will be given by:

The volume of a right triangular prism = ( height × Base Area)

height = √(36 - 9)

          = √27

The volume of a right triangular prism = √27 × 157.2

                                                                = 816.83

Step-by-step explanation:

$920 - $60x

Step-by-step explanation:

after one month, he try would have taken out 60 x 1 dollars, after two months, 60 x 2, 3 months, 60 x 3, etc. so after x months he would have taken out 60x (60 times x) dollars. if he starts with 920 dollars, he would be left with $920 - $60x.

<3

The minimum amount he needs to save each month in order to be able to pay for his first year of college is $375.

The first step is to determine the total amount he needs to save.

Amount he needs to save = $12,000 - $7500 = $4,500

The second step is to divide $4500 by 12.

4500 / 12 = $375

Step-by-step explanation:

There is no options but I think the graph equation is

[tex]f(x) = \sqrt{x} + 2[/tex]

The situation in which triangles will be made congruent for sure is given by: Option ( iii ) Both making a triangle TRY with right angle at T and sides TR =4 cm and RY =5cm

Suppose it is given that two triangles ΔABC ≅ ΔDEF

Then that means ΔABC and ΔDEF are congruent. Congruent triangles are exact same triangles, but they might be placed at different positions.

The order in which the congruency is written matters.

For ΔABC ≅ ΔDEF, we have all of their corresponding elements like angle and sides congruent.

Thus, we get:

[tex]\rm m\angle A = m\angle D \: or \: \: \angle A \cong \angle D \angle B = \angle E\\\\\rm m\angle B = m\angle E \: or \: \: \angle B \cong \angle E \\\\\rm m\angle C = m\angle F \: or \: \: \angle C \cong \angle F \\\\\rm |AB| = |DE| \: \: or \: \: AB \cong DE\\\\\rm |AC| = |DF| \: \: or \: \: AC \cong DF\\\\\rm |BC| = |EF| \: \: or \: \: BC \cong EF[/tex]

(|AB| denotes length of line segment AB, and so on for others).

For two triangles being congruent, we need at least:

Checking all the options:

Only one side and one angle are not enough.

Two equilateral triangles are not necessary to be congruent. Example, one equilateral triangle has sides of 3 units, and other triangle has sides of 5 units.

Two sides TR and RY and a non-included angle T is given. This doesn't satisfy SAS' condition. But since it is given that:

Angle T is right angled, so we now know that RY is going to be hypotenuse.

Using this fact, and the fact that |RY| = 5 cm, |TR| = 4 cm, and Pythagoras theorem, we can get |TY| = 3 cm.

Thus, it will complete SSS condition, and therefore, by SSS congruency, the triangles made in this case would be congruent.

All angles(corresponding) being equal implies similarity, but not congruence.

Thus, the situation in which triangles will be made congruent for sure is given by: Option ( iii ) Both making a triangle TRY with right angle at T and sides TR =4 cm and RY =5cm
