Answer:

42.3

Step-by-step explanation:

3.6 × (3) + 4.5 × (7)

= 10.8 + 31.5

= 42.3

Answer:

351

Step-by-step explanation:

3.6 x 3 = 10.8                                3.6 x (3) + 4.5 x (7)

4.5 x 7 = 31.5                                       10.8 + 31.5

10.8 + 31.5 =  42.3                                  42.3

1) It's February and you go to the store to buy some food for your pets. You have a Great

Dane and a Savannah cat. The Dane eats 3 times as much as your cat so his food

cost $60 for the big bag and he eats that in one week. The Savannah cats food cost

$15 a bag and it lasts him one week as well. You are there to buy food for the month

and have no more than $300 total to spend. Can you afford a month's worth of food?

a) If you bought the cat 6 weeks worth of food, how many weeks worth can you

buy your Great Dane?

7. Definition of midpoint

5. Definition of angle bisector

1reflexive property of equality

According to the Angle Addition Postulate, the total of two angle measurements connected by a common ray equals the size of the angle they produce.

Given,  ∠PSR = ∠PST, and PS bisects the angle ∠ QSU.

Thus From the figure, ∠TSU = ∠QSR

And also given PS bisects the angle ∠ QSU. and p is the same

Thus From the figure  ∠PSU = ∠PSQ

Additive property of length:

The additive property of equality in an equation asserts that the sides stay equal whether we add or subtract the same amount from both sides of the equation. For entire numbers as well, this property is valid.

Definition of angle bisector:

A "Bisector" in geometry is a line that splits a line into two distinct or equal sections. It is applied to angles and line segments.

Definition of an equilateral triangle:

An equilateral triangle in geometry is a triangle with three equal-length sides. An equilateral triangle has congruent sides, which means that each side is the same length. Additionally, each inside angle is identical (60 degrees).

Definition of midpoint:

the location on a line that is equally spaced from both ends. a time interval that lies halfway between the start and finish of an event.

Verticals angle theorem:

According to this theorem, when two straight lines cross, they create two sets of linear pairs with matching angles. The adjacent angles created by the junction of these two lines are likewise said to be supplementary, or equivalent to 180 degrees.

Therefore, Since ∠PSR = ∠PST and PS bisects the angle ∠QSU, ∠TSU = ∠QSR. Since PS divides the angle ∠QSU, ∠PSU = ∠PSQ. It is the same because PS is the same line.

Answer:

3.28 cm

Step-by-step explanation:

The calculation is given below:

we assume the following things

R denotes the radius of the circle

And, A denotes An arc  

Now , the length of the arc is  

L = (A ÷ 360°) × 2 × 3.14 × R

According to the question

R = 6 cm

Angle = 5 minutes and 15 seconds

The clock could complete its revolution in 60 minutes  

Therefore  

60 minutes = 360°

Also

1 min = 60 seconds

So  

1 seconds =  1min ÷ 60seconds  

Now for 15 seconds it is

= 15 seconds × (1 ÷ 60)

= (15 ÷ 60) min

= 0.25 min

 And for 5 minutes and 15 seconds, it is  

= 5 min + 0.25 min

= 5.25 min

Also

60 minutes = 360°

So,  

1 minute = 360° ÷ 60min

Now For  5.25min

= (5.25min) × (360° ÷ 60min)

= 31.5°

Finally the length would be    

L = (31.5° ÷ 360°) × 2 × 3.14 × 6cm

= 3.28 cm

Answer:

A factor can be a number, variable, term, or a longer expression. For example ... In the expression 2x+4y− 9 , the term 9 is a constant. Like Terms: Terms that contain the same variables such as 2m , 6m or 3xy and 7xy .

Step-by-step explanation:

Factor, in mathematics, a number or algebraic expression that divides another ... For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12 .

Answer:

Step-by-step explanation:

As we know that from a theorem,

A greater angle of a triangle is opposite a greater side. Let ABC be a triangle in which angle ABC is greater than angle BCA; then side AC is also greater than side AB. For if it is not greater, then AC is either equal to AB or less.

As we have  angle A =120 so it means the other 2 angles will be less than angle A , hence the opposite side to angle A is BC ,

Hence BC line is the longest line in triangle ABC

Case : BC is the longest side

#Remember that the total degree of triangle is 180°

#If A° = 120° so B° + C° = 180°-120°

B° + C° = 60°

#From here, you already know that even the total of both of B and C is less than 120° which is the degree of A.

#If you are gonna find the length of BC, then you need to use trigonometry which will be

BC/sinA = AB/sinB = AC/sinC

#so, from here you can know that BC will be the longest one, because bigger the value, in sin, will be smaller the value

Answer:

8.5

Step-by-step explanation:

The required value of the number is 8.5 which is twice the difference between a number and 5 is 7​.

To solve this problem, we first need to express the given information in terms of a mathematical equation.

The statement "Twice the difference of a number and 5 is 7" can be represented as the equation 2 × (x - 5) = 7, where x is the number we're trying to find.

Next, we can solve this equation to find the value of x. To do this, we can first distribute the 2 on the left-hand side of the equation to get 2x - 10 = 7.

Then, we can add 10 to both sides of the equation to get 2x = 17.

Finally, we can divide both sides of the equation by 2 to get x = 17/2 = 8.5.

Therefore, the required value of the number is 8.5.
