The height of the tide at the Bay of Fundy in New Brunswick decreases 36 feet in 6 hours. What is the mean hourly change in the height in feet per hour?

help

I started by labeling the right angle (Angle C) 90º. Next, I wrote down everything in one equation.

2x + 90 + 3x - 20 = 180º (180 degrees in a triangle)

Next, I add 20 on both sides.

2x + 90 + 3x = 200º

I combine like terms (2x and 3x)

5x + 90 = 200º

I subtract 90 from both sides.

5x = 110º

Divide 110 by 5 to get x.

x = 22

======

For problem two, I label all the angles I know.

49º + 80º + r = 180º

I add 80 and 49.

129º + r = 180º

I subtract 180 and 129 and get 51º, which is your angle for R.

For angle X, you know that angle R plus angle X equals half of a circle, which is 180º

We know from before that 129º is 180º without R, so X is 129º

I hope this helps! Let me know if I'm wrong!

The distance from Dan's house to Samuel's house is 4 km

The distance from Dan to Samuel house, Dan to Cindy house and Samuel to Cindy house forms a right angled triangle.

Distance from Dan to Samuel house = x, Distance from Dan to Cindy house = 3 km and Distance from Cindy to Samuel house = 5 km

Pythagoras theorem shows the relationship between the lengths of a right angled triangle.

Using Pythagoras theorem:

5² = x² + 3²

25 = x² + 9

x² = 16

x = 4 km

Hence the distance from Dan's house to Samuel's house is 4 km

Answer:

 149sx+127v+275f =

276

Step-by-step explanation:

multiply all the numbers than add you get the answer  149sx+127v+275f

149s + 127v + 275f  is expression represents the total amount of money the Smiths will spend, before sales tax, based on the number of sports sets they buy.

An expression is combination of variables, numbers and operators.

The total amount of money the Smiths will spend on the soccer, volleyball, and football training sets can be represented by the expression:

149s + 127v + 275f

Here, 149s represents the cost of s soccer training sets,

127v represents the cost of v volleyball training sets, and

275f represents the cost of f football training sets.

To find the total amount of money the Smiths will spend based on the number of sports sets they buy, simply substitute the corresponding values of s, v, and f into the expression above and simplify.

Hence, 149s + 127v + 275f  is expression represents the total amount of money the Smiths will spend, before sales tax, based on the number of sports sets they buy.

Answer:

Head Jamz

Step-by-step explanation:

Noisy Music Regular Price $250 Clearance Special - 15% off

If 15% is off then we pay only 100-15 =85% from the original price.

$250 / 100 % = x / 85%

x= 250*85/100 = $ 212.5

Loud N Sharp Regular Price $200 $5 off for every $100 spent

If the price is 200 then will get $5+$5 =$10 discount

Final price will be 200-10 = $ 180

Music Mart Regular Price $300 Mail-in rebate for $115

$300-$115 = $ 185

Head Jamz Regular Price $225 Manager special – 25% off

If 25% is off we only pay 75% of the original price

$225/ 100% = x / 75%

x= 225*75/ 100 = $168.75 is the lowest price

Step 3: Subtract f(4) from f(3).

Therefore, the answer is 2.

Inequalities are used to compare unequal expressions.

The actual comparison is:[tex]\mathbf{-3.5 < 5}[/tex] or [tex]\mathbf{5 > -3.5}[/tex]

The temperatures are given as:

[tex]\mathbf{Temperature = -3.5F,\ \ 5F,\ \ 1.5F,\ \ -0.5F,\ \ -2F,\ \ 2.5F,\ \ -4F}[/tex]

From the above list, we have:

[tex]\mathbf{Day \ 1= -3.5F}[/tex]

[tex]\mathbf{Day \ 2= 5F}[/tex]

By comparison,

[tex]\mathbf{-3.5 < 5}[/tex] or [tex]\mathbf{5 > -3.5}[/tex]

Using absolute values, the inequalities are:

[tex]\mathbf{|-3.5| < |5|}[/tex] or [tex]\mathbf{|5| > |-3.5|}[/tex]

area = (width * height) / 2

area = 6 * 3 / 2

area = 18 / 2

area = 9 square units²

Answer:

9 [tex]units^{2}[/tex]

Step-by-step explanation:

The formula to find the area of a triangle is [tex]A=\frac{1}{2}b*h[/tex] where b is the base or bottom of the triangle and h is the height of the triangle.

The base of the triangle in the picture is 6 units.

The height of the triangle in the picture is 3 units.

Substituting these values into the area formula:

[tex]A=\frac{1}{2}(6*3)=\frac{1}{2}(18)=9[/tex]

So the area of the triangle is 9 [tex]units^{2}[/tex]

Se prepararon 68 porciones.

Lo que sabemos en principio es que, por cada porción de arroz, se necesitan 70 gramos de arroz.

Sabemos que en total se utilizan 4,760 gramos de arroz. Para saber cuantas porciones se prepararon, hay que tomar el cociente entre la cantidad total utilizada y lo que se usa para cada porción.

Esto nos da:

4,760g/70g = 68

$5.29 per pair of socks

Step-by-step explanation:

26.45/5=5.29

Answer:

Line passing through (2,2) is parallel to X - 2Y = 4, so, the slope is same as given line.

m = -a/b = -1/-2 = 1/2

The equation is

(Y - Y1) = m(X - X1) => Y - 2 = 1/2(X - 2) =>

2Y - 4 = X - 2 => | X - 2Y = -2 |
