Answer:

The actual area of the town is 14 miles.

Step-by-step explanation:

Since you know that the scale is 1 inch:4 miles and that the map shows a town with an area of 3.5 inches, you can expressed this as follows:

Scale: 1 inch:4 miles

map area: 3.5 inches

If the actual area is x, you can say that:

3.5:x=1:4

This would be:

[tex]\frac{3.5}{x}=\frac{1}{4}[/tex]

Now, you can solve for x:

x=(3.5*4)/1

x=14

According to this, the answer is that the actual area of the town is 14 miles.

Answer:

D since I had a test question of this and got it right.

Step-by-step explanation:

Option D is correct, credit cards can help you stay within budget since you can't spend more than what's in your linked bank account.

A credit card is a payment card issued to users to enable the cardholder to pay a merchant for goods and services based on the cardholder's accrued debt.

Credit cards can help you stay within budget since you can't spend more than what's in your linked bank account is not accurate because credit cards actually allow users to spend more than what's in their linked bank account, which can lead to overspending and accumulating debt.

Unlike debit cards, which are linked directly to a checking account, credit cards allow users to borrow money from a lender up to a certain credit limit.

This means that users can potentially spend more than they have available in their bank account and then pay off the balance over time with interest.

Hence, Option D is correct, credit cards can help you stay within budget since you can't spend more than what's in your linked bank account.

Step-by-step explanation:

10 x 16

Answer:

the answer is 80

Step-by-step explanation:

Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.

A=bh=10·8=80

Answer:

$11 approx

Step-by-step explanation:

Given data

Total cost of album= $11.65

Tax= 6%

Let the cost of the album without tax be x

x+ 6/100*x=11.65

x+0.06x=11.65

1.06x=11.65

x= 11.65/1.06

x=10.99

Hence the cost is $11 approx

Answer:

complete angle is 360°

360 - 39

329°

Answer: 19.26

Step-by-step explanation: 40% of 30 can be found like 30(0.40), which equals 12, since the game is 40% of they are getting $12 off. 30-12=18. The sales tax is 7% or 0.07 so you can find it by doing 18(0.07) which is 1.26, now you just add 1.26 and 18 which is 19.26.

Answer:

C. (7x + 4)(7x − 4)

Step-by-step explanation:

Given expression:

49x² - 16

Using difference of two squares:

A² - B² = (A + B)(A - B)

49x² - 16 = (7x)² - (4)²

= (7x + 4)(7x - 4)

C. (7x + 4)(7x − 4)

Check:

(7x + 4)(7x − 4)

Open parenthesis

= 49x² - 28x + 28x - 16

= 49x² - 16

Answer:

16

Step-by-step explanation:

Given the recursive function tn= tn-1 + tn-2 where t1 = 4, t2 = 6

We are to find t4

t4 = t₄₋₁ + t₄₋₂

t₄ = t₃ + t₂

Get t₃

t₃ = t₂ + t₁

t₃ = 6 + 4

t₃ = 10

Get t₄

Recall that t₄ = t₃ + t₂

t₄ = 10 + 6

t₄ = 16

Hence the fourth term of the sequence is 16

Answer:

146.8 m^2 to nearest tenth.

Step-by-step explanation:

The surface area = area of the middle 4 rectangles + 2 * curved area + 4 * the semi-circles

= 2*4*6 + 2 *3*6  +  2 * π*2*3 + 4 * 1/2* π 2^2

= 84 + 12π + 8π

= 84 + 20π

= 146.83.

base= 5+h

height= h

area= 1/2bh, so since our area us 18cm^2

therefore 18=1/2*b*h

18*2=(5+h)*h

36=5h+h^2

h^2+5h-36=0 ( for quadratic equation)

h^2+9h-4h-36=0

(h^2+9h)(-4h-36)=0

h(h+9)-4(h+9)=0

(h-4)(h+9)=0

h=4 or h= -9

Answer:

10 x 10 x 10 x 10 X10 x 10

Step-by-step explanation:

10 x 10 = 100 x 10 = 1000 x 10=10000 x 10=100000 x 10= 1,000,000

After multiply the numbers, The correct expression with the same value as ''10 to the power of 6'' is,

⇒ 10⁶

Or, ⇒ 10,00,000

The multiplication of the numbers means to add or sum a number to itself by a particular number of times.

And, Multiplication can be viewed as a process of repeated addition.

We have to given that;

Answer:

180ft

Step-by-step explanation:

By using the formula, we do Pi (3) x the radius which is 6² then x by the height, so, we do 3 x 6² x 5. 6² is 36. 3 x 36 = 108. Next, we do 5 x 108. This gives us 540. Now, we have to divide by 3. This makes our answer 180ft.

The perimeter of a square is 52 m. What is the area of the square ?

Perimeter of a square = 52 m

4 × side = 52

side = [tex] \frac{52}{4} [/tex]

side = 13

So, area of square = (side)² = (13)² = 169 sq m.

Answer:

A = 169 m²

Step-by-step explanation:

The sides (s) of a square are equal , then

s = perimeter ÷ 4 = 52 ÷ 4 = 13 m

The area (A) of a square is calculated as

A = s² = 13² = 169 m²
