Write an algebraic expression for the phrase:six times a length w

Answers

Answer 1

Answer: Six times a length w means that we will repeat the w six times.

This can be expressed algebraically in two ways:
1- using addition:
six times a length w = w+w+w+w+w+w
2- using multiplication:
six times a length w = 6*w

Which strategies can be used to solve this problem? The population of Grayville is 2,345 people. Rosetown has 1,123 fewer people than Grayville. Newtown has 1,020 more people than Rosetown. How many people live in Newtown?

Choose all answers that are correct.

A.
Translate into an equation.
2,345 – 1,123 + 1,020 = p

B.
Work backward.
Add 1,020 to the population of Rosetown (1,123). Subtract this from the population of Grayville (2,345).

C.
Use logical reasoning.
Start with the population you already know (Grayville = 2,345). Subtract Rosetown's 1,123 fewer people than Grayville. Add 1,020 to this amount because Newtown has 1,020 more people than Rosetown.

D.
Draw a diagram.
Draw 3 large circles. Write 2,345 in the first circle and write 1,123 in the second circle. Add the 2 amounts and subtract 1,020 from the sum. Write this amount in the third circle.

Answers

Both A. and C. will give you the same correct answer: 2,242 people. They're the same problem C. is just written longer :) hope this helps

In right triangle ABC, where C is the right angle : b = 12 and B = 33°. Find A, a, and c to the nearest tenth.

Answers

Answer:

A= 57° , a= 7.79 and c = 14.30

Step-by-step explanation:

In a given right triangle,

We have, b =12 ,B =33° and C =90°

We can find Angle A.

Angle sum property of triangle:

i.e A + B + C = 180°

A + 33° + 90° = 180°

A = 57°

Next, by using trigonometry

tanB = Perpendicular /Base = a /b

Here B =33° , a = ? , b = 12

So, tan 33° = a/12

0.6494 = a/12

a = 7.79

So we got a and b. By using Pythagoras theorem we determine c.

c^2 = a^2 + b^2

c^2 = 7.79^2 + 12^2

c = √(2046841) = 14.30

The expression 12a+7s is the cost, in dollars, for a adults s students to enter the local marching band competition. Find the total cost for 4 adults and 30 students.Before you delete this I did try on my own and this has been confusing me

Answers

If 12A is equal to one adult, then this means that one adult will cost $12 to enter.
The same applies for the students, if 7s is equal to one student, then the cost of one student is $7.
As you've got four adults, then you need to find the cost of 4, and you do this by multiply 4 by 12.
4x12=$48
As you've got 30 students, you then need to multiply 30 by 7.
30x7=$210.
To find the total cost, you've then got to add $48 and $210 together.
$48+$210= $258.

Therefore, the total cost for 4 adults and 30 students is $258
Hope this helps :)

a=$4, s=$30

=12($4)+7($30)
=$48+$210
=$258
