Answer:

The two numbers are 17 and 44.

Step-by-step explanation:

x --> smaller number

y --> larger number

x + y = 61

y = 3x - 7

x + 3x - 7 = 61

4x - 7 = 61

4x = 68

x = 17

y = 3(17) - 7

y = 51 - 7

Step-by-step explanation: because each gram is 1000 milligrams

If  the price of a used car is discounted $200 each week then the grapg will be linearly decreasing in nature

A linear graph can be either increasing, decreasing or constant.

Here the price of the car is being discounted $200 every week, so as the number of weeks increase, the price of the car decreases

So, the graph for this situation will be linearly decreasing.

The slope of this kind of graph is negative/

Answer:

27 miles, 40.5 miles, and 47.25 miles

Step-by-step explanation:

9 miles in 2/3 hours. To get to a whole number, we can multiply by the reciprocal of 2/3, which is 3/2. 2/3*3/2=1. Now lets multiply 9 by 3/2. 9*3/2=13.5

We now have a unit rate which is 13.5 miles each hour.

Now lets solve for 2 hours.

13.5*2= 27 miles

Now lets solve for 3 hours.

13.5*3=40.5 miles

Now lets solve for 3.5

13.5*3.5= 47.25 miles

The values of m<4 and m<6 are 160° and 20° respectively

To solve this problem, we need some angle geometry knowledge:

Given that: m<6 = 1/8 m<4

Since m<6 = 1/8 m<4. Thus, m<4 = 8.m<6

m<6+ m<4 =  m<6 + 8.m<6 = 9.m<6    (Algebra)

m<6+ 8.m<__ = 180° will be:

m<6+ 8.m<6 = 180°      

Note: m<6 + m<5 = 180° (angles on a straight line) and m<5 = m<6 (alternate angles)

m<6+ 8.m<6 = 180°

9.m<6 = 180°

m<6 = 180/9 = 20°

m<4 = 8 x m<6

m<4 = 8 x 20° = 160°

Therefore, the values of m<4 = 160° and m<6 = 20°

As we know that if A is complete the work of z in x days and B is complete the same work (z) in y days then both of can do complete work together then Equation of both A and B are completing work (z) together in

( 1/x + 1/y = 1/z ) days

Since Betty can mow a lawn is 120 minutes, then

Betty's mowing rate is 1/120th of a lanw per minute.

Since Bullwinkle can mow a lawn is 40 minutes, then Bullwinkle mowing rate is 1/40th of a lawn per minute.

Suppose working together they can a lawn in x minutes.

both together they can mow a lawn is x minutes, then their combined mowing rate is 1/x th of a lawn per minute.

To get the equation,

the sum of their mowing rates must equal their combined mowing rate,

1/40 + 1/120 = 1/x

Solve that by multiplying through by LCD of 40 and 120 is 120 then 4x = 120 => x = 30

If the dealer gives Bernie the listed trade- in price for his car,  he will pay $391.97  monthly.

Given that,

Bernie has decided to purchase a new car of $ 18,575.

The sales tax is 7.40%

Now,

18,575 x 7.40% = 1,374.55

Now, summing up the result of sales tax and purchase price, we get,

18,575 + 1,374.55 = 19,949.55

Bernie will give registration fees of $795

and, a documentation fees: $110

Now , we will sum up all the above information, i.e.,  

= 19,949.55 + 795 + 110

= 20,854.55

Now, divide the result of documentation fees and registration fees by 5

                         20,854.55 ÷ 5 = 4,170.91

Dividing the above result by 12,                      

                          4,170.91 ÷ 12 = 347.58

Now, the finance the rest of the cost for five years at an interest rate 12.77%.

95km/h is the average speed for the whole journey

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement

Given,

Simon drives 75 km at an average speed of 120 km/h

9 km at 70 km/h without stopping.

We need to find the average speed.

Average speed = Total distance/Total time

The total distance is 75km+9km

84 km

The average speed is sum of speeds by two

120+70=190/2=95km/h

Hence, 95km/h is the average speed for the whole journey

The smallest possible perimeter of the triangle is, 72.4 inches.

What is perimeter?

The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimeters, meters, inches, and feet.

As given the longest side of an acute triangle measure 30 inches.

The two remaining sides' combined length must be longer than the opposite side.

The sum of the two remaining sides should be greater than 30 inches if the side is 30.

Assume the other two sides add up to 31 inches.

So, The perimeter of a triangle is equal to the sum of its three sides, which comes to 30 + 31 = 64 inches.

Consequently, the circumference must be greater than 64 inches.

Hence, based on the possibilities, the triangle's smallest conceivable perimeter is 72.4 inches.

Yes, the graphs of a power function and its inverse are symmetric about the line y=x.

What is an inverse function?

A function that "undoes" another function is called an inverse. In other words, if f(x) yields y, then y entered into the inverse of f yields the output x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f⁻¹.

What is a power function?

Any function where y = xⁿ, where n is any real constant integer, is referred to be a power function. In reality, many of our parent functions, including linear and quadratic functions, are power functions.

Here,

The graphs of self-inverse functions are symmetrical about the line y=x. The domain of a one-to-one function f is the same as the range of its inverse f⁻¹ and the range of f is the same as the domain of f⁻¹.

Hence, the graphs of a power function and its inverse are symmetric about the line y=x.

The rule for given translation is (x,y)→(x + 3, y - 4).

In mathematics, the phrases translation, rotation, and reflection are all used to describe the change of forms. This refers to a form moving beyond a mirror line or a fixed point. While being translated, rotated, or reflected, the shape doesn't change. The constant rotation of a shape around a fixed point or across the mirror line is known as translation. Rotation defines the way a form moves about a central axis. Shapes can be rotated by a specific number of degrees either clockwise or counterclockwise.

The rule for translation of given figure will be,

We need to move x for 3 units to left and y for 4 units downwards to get the translation, so the rule is:

(x,y)→(x + 3, y - 4).

Therefore, the rule for given translation is (x,y)→(x + 3, y - 4).

Let x represent the cost of watermelon

y = cost of napkin + cost of paper plates

The tax rate on non-food items is 5%, hence:

5% of y = 0.19

0.05y = 0.19

y = $3.8
