Let 'x' be the number of pounds of Yurly's package and let 'y' be the number of pounds of Anduray's package. Since the combined weight of both packages is 9 pounds, then:

now, we have that Yurly's package weights three pounds more than two times the weight of Anduray's, we can write this as:

thus, we have the following system of equations to represent this situation:

The side opposite to 30 degree angle is 1/2. So,

The measures of the numbered angles in the rhombus ABCD if m∠ABC = 49° are m∠1 = 24.5°, m∠2 = 90°, m∠3 = 24.5° and m∠4 = 65.5°.

We are given:

A rhombus ABCD and m∠ABC = 49°.

The diagonal of the rhombus divides the angles into 2 equal parts. Therefore,

m∠1 = m∠ABC / 2 = 49 / 2 = 24.5°

The diagonal AC is perpendicular to the diagonal DB.

And we know that diagonals bisect each at right angles.

So, m∠2 = 90°.

Opposite angles of the rhombus are equal.

Therefore,

∠B = ∠D

multiply both sides by 1/2, we will get;

1/2 ∠B = 1/2 ∠D

m∠1 = m∠3 = 24.5°

Sum of angles in a quadrilateral = 360°

360 -  98 = 262°

∠A = ∠C = 262 / 2 = 131

Therefore,

m∠4 = 1 / 2 ∠C

m∠4 = 1 /2 * 131

m∠4 = 65.5°

Thus, the measures of the numbered angles in the rhombus ABCD if m∠ABC = 49° are m∠1 = 24.5°, m∠2 = 90°, m∠3 = 24.5° and m∠4 = 65.5°.

Answer:

y=-1/5x-4

Step-by-step explanation:

just use y=mx+b formula, slope always goes for m and y intercept for b

1.

What do you know?

the troposphere extends 8 to 20 km above the Earth's surface. The surface temperature is 15°C and decreases at a rate of 6.5°C per kilometer away.

What do you want to find out?

The temperature at any point of the troposphere

What kind of answer do you expect?

Any value below 15°C

2. Define variables,

T is for temperature, and

d is the distance away from the surface

3. What is the b -value

b = 15

which is the Earth's surface temperature or the initial temperature for our problem

4. What is the slope

the slope 'm' equals -6.5

which means that the temperature decreases 6.5°C per km

5. write the equation

the general form for this equations is y = b + mx

thus, for our problem, the equation is: T = 15 - 6.5*d

6.

a) the slope represents the rate of change of temperature with respect to distance, since m = -6.5 °C/km , this means the troposphere is getting 6.5 °C colder per km away from Earth's surface

b) the y-intercept represents the Earth's surface temperature

Graph:

7. identify 3 points

when d = 0 then T = 15, so our first point is (0,15)

when d = 1 then T = 15 - 6.5 = 8.5 , so our second point is (1,8.5)

when d = 2 then T = 15 - 13 = 2 so our third point is (2,2)

8. calculate the slope

let's use this equation and this set of points,

let's replace and solve

We can see that it does match the slope from our model, which is -6.5

9. graph the line and the points,

10. Complete the sentence

... ends between 8 km and 20 km above Earth.

11. temperature at the farthest point

True about translations is they can help you see if two figures are congruent

What are translations?

In mathematics, a translation is an up, down, left, or right movement of a shape. Because the translated shapes appear to be exactly the same size as the original ones, they are consistent with one another. Just one or more directions have been altered. There is no change in the shape because it is simply being moved from one location to another.

Each point in a figure is moved the same distance in the same direction using a type of transformation known as translation.

Hence, they can help you see if two figures are congruent.

Answer:

Rides cost $4

Games cost $2.50

Step-by-step explanation:

Let g = cost of games

Let r = cost of rides

6g + 3r = 27

2g + 9r = 41  Multiple this through by -3 and then add to the equation above.

-3(2g + 9r) = (41) -3

-6g - 27r = - 123

6g + 3r = 27

       -24r = -96  Divide both sides by -24

r = 4  This is the cost of the rides.

Plug is 4 for r in either of the two original equations to solve for g

6g + 3r = 27

6g + 3(4) = 27

6g + 12 = 27  Subtract 12 from both sides

6g = 15  Divide both sides by 6

g = 2.5  This is the cost of the games.

Answer:

∡BCA = 29

∡BOC = 58

Explanation:

The angles BDC and BAC form the same arc on the circle, the arc BC. Then, these angles have the same measure, so

∡BCA = ∡BDC

∡BCA = 29

Then, we can use the inscribed angle theorem to find the arc BC as follows

Therefore, arc BC has a measure of 58 degrees, which means that ∡BOC is equal to

∡BOC = Arc BC

∡BOC = 58

So, the answers are

∡BCA = 29

∡BOC = 58

She sold 125 sandwiches and 175 viands as per the equation using substitution method as the definition of substitution method says, "The algebraic approach to solving simultaneous linear equations is known as substitution method. The value of one variable from one equation is substituted in the other equation in this method, as the name implies".

A mathematical formula is an equation that uses algebraic operations like add, subtract, multiply, divide, raise to a power, take the natural logarithm, take the cosine, or some combination of operations to express one variable as a combination of other variable(s). One-step equations can be solved in four different ways: by adding, subtracting, multiplying, and dividing. In an equation, both sides will remain equal if we add the same amount to each side. The "scale" (or equation) must ALWAYS be balanced when solving math equations so that both sides are ALWAYS equal.

Here,

Let x be the sandwiches she sold and y be the viands she sold.

x+y=300

y=50+x
