Martha wants to buy a laptop case for $40. So far she has saved $27. How much more does she need in order to have enough money to purchase the laptop case? Which equation correctly represent this situation?

Answer:

This is your answer ☺️☺️

Value of x is 19 cm.

The area of a trapezium is defined as the number of unit squares that can fit into it . The area of a trapezium can be calculated using the lengths of two of its parallel sides and the distance (height) between them. The formula to calculate the area (A) of a trapezium using base and height is given as,

A = ½ (a + b) h where,

a and b = bases of trapezium, and,

h = height (the perpendicular distance between a and b)

Given

Area of trapezium = 48 [tex]cm^{2}[/tex]

Area of trapezium = [tex]\frac{(AB+DC).h}{2}[/tex]

48 =  [tex]\frac{(AB+DC).h}{2}[/tex]

⇒ 48 = [tex]\frac{(5+x).(4)}{2}[/tex]

⇒ 96 = (5+x).4

⇒ 5 + x = [tex]\frac{96}{4}[/tex]

⇒ 5 + x = 24

⇒ x = 24 - 5

⇒ x = 19 cm

Hence, Value of x is 19 cm.

Answer:

Step-by-step explanation:

Answer:

P = $ 482.00

Equation:

P = I / rt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

P = 72.3 / ( 0.05 × 3 ) = 482

P = $ 482.00

The principal required to

accumulate interest of $ 72.30

on a rate of 5% per year for 3 years is $ 482.00.

Answer:

y=-3x+5

Step-by-step explanation:

The resulting equivalent expression is (6x^3 - 6x^2 +36)•(5y^2-9)

Given the functions:

d(x) = 2x^3 - 2x^2 +12 c(y) = 5y^2 - 9

We are to find the expression 3d(x) • c(y)

3d(x) = 3(2x^3 - 2x^2 +12)

3d(x) = 6x^3 - 6x^2 +36

c(y) = 5y^2 - 9

Substitute into the expression:

3d(x) • c(y) = 6x^3 - 6x^2 +36(5y^2-9)

Hence the resulting equivalent expression is (6x^3 - 6x^2 +36)•(5y^2-9)

Answer:

x = 27

Step-by-step explanation:

A circle adds up to 360 degrees. So we make this equation:

2x+21 + 5x+6 + 54 + 90 = 360

Combine like terms:

7x + 171 = 360

Subtract both sides by 171

7x = 189

Divide both sides by 7

x = 27

Answer:

Step-by-step explanation:

this has a bunch of "implied"  things that you're supposed to know.   one is that all the way around a circle is 360°   two is that if you know the angle on the interior.. that is also the arc length.. so knowing those things  we can say

360 = 54 + 2x + 21 + 5x + 6 + 90

put like terms together

360 = 171 + 7x

189 = 7x

27 = x

Answer:

1)  cos(29) x 13 = 11.4

2) 18/sin(63) = 20.2

3) 14/tan(71) = 4.8

4) tan(18) x 11 = 3.6

5) 21/cos(35) = 25.6

6) tan(43) x 20 = 18.7

7) 9/sin(33) = 16.5

8) 17/tan(67) = 7.2

9) cos(38) x 19 = 14.97 or 15 (rounded to nearest 10th)

10) sin(59) x 26 = 22.3

Update: now all rounded to nearest 10th

Answer:

30°, 60°, 90°

Step-by-step explanation:

sum the parts of the ratio, 1 + 2 + 3 = 6 parts

divide the sum of the angles in a triangle. 180° by 6 to find the value of one part of the ratio.

180° ÷ 6 = 30° ← value of 1 part of the ratio , then

2 parts = 2 × 30° = 60°

3 parts = 3 × 30° = 90°

The 3 angles are 30°, 60° and 90°

Answer:

I am not the best at math but I know that u can't change the bottom half of the fraction so it would just be four and then multiply the five and the three which would be fifteen. The answer would be 15/4ths. So you want to color in 15 boxes. Hopefully I could be of some kind of help to you!

Answer:

color in 15 boxes

15/32

Step-by-step explanation:

first off, the points are split so I'm only getting 12, just so that you know.

so 1/8x1/4 is 1/32, so each box is 1/32.

5/8x3/4=15/32 (multiply the top of the first with the top of the second and the bottom of the first with the bottom of the second)

so color in 15 boxes and the answer to the multiplication is 15/32

Answer: 0

Step-by-step explanation: 18a + 3 = 3

                                                     -3    -3

                                                   --------------

                                              18a   =    0  you can't divide 18 and zero it would be 0

Answer:

So to factorize an expression, you put it into a form where if you expanded the brackets, you'd get the given expression.. if that makes sense. Therefore, you need to multiply the 3 by something to get 18a, and so the first term is 6a. You don't need to multiply 3 by anything to get 3, so the second term is 1. The final result looks like this :

3(6a + 1)

Answer:

.85 times the cost to make the shirt

Step-by-step explanation:

Let x represent cost to make the shirt.

Today, the shirt is in a 15 percent discount from its normal price.

Discount = 15/100 * x = 0.15x

Current cost = Original cost - discount

Current cost = x - 0.15x = 0.85x

The answer is;

.85 times the cost to make the shirt
