At a particular fast food restaurant, tacos cost $1.29 and
burritos cost $2.19. Michael spent a total of $42.93 at the
restaurant to buy food for a party. If he purchased half as
many burritos as tacos, how many tacos did he buy?

Answers

Answer 1

Answer:

9 burritos and 18 tacos

Step-by-step explanation:

We can start this problem by assigning a variable to our unknowns.

Let's name x the number of burritos he buys.

The question states he buys half as many burritos as tacos.

Therefore, the number of tacos he bought is 2x.

Let's set up an equation.

(Cost of burrito)(number of burritos)+(Cost of taco)(number of tacos)=Total Cost

2.19x+1.29(2x)=42.93

Simplify

2.19x+2.58x=42.93

4.77x=42.93

x=9

Michael bought 9 burritos.

2*9=18

Michael bought 18 tacos.

Answer 2

Answer:

[tex] \displaystyle 18[/tex]

Step-by-step explanation:

we are given that,

tacos cost $1.29 burritos cost $2.19Michael spent a total of $42.93he purchased half as many burritos as tacos

let the number of tacos and burritos be t and b respectively

according to the 3rd condition we get:

[tex] \displaystyle 1.29t + 2.19b = 42.93[/tex]

according to the 4th condition we obtain:

[tex] \displaystyle t = 2b[/tex]

therefore our system of linear equation is

[tex]\begin{cases}\displaystyle t=2b \\ \displaystyle 1.29t + 2.19b = 42.93\end{cases}[/tex]

so now we end up with a system of linear equation in order to solve the equation we can consider substitution method

so substitute the value of t which yields:

[tex] \displaystyle 1.29 \cdot 2b+ 2.19b = 42.93[/tex]

simplify multiplication:

[tex] \displaystyle 2.58b+ 2.19b = 42.93[/tex]

since we have same variable we can consider the like terms:

[tex] \displaystyle 4.77b = 42.93[/tex]

divide both sides by 4.77:

[tex] \displaystyle \frac{4.77b }{4.77}= \frac{ 42.93}{4.77}[/tex]

reduce fraction:

[tex] \displaystyle \bcancel{ \frac{4.77b }{4.77}}= \cancel \frac{ \stackrel{ \large9}{ 42.93}}{4.77}[/tex]

[tex] \displaystyle b = 9[/tex]

now substitute the value of b:

[tex] \displaystyle t = 2.9[/tex]

simplify multiplication:

[tex] \displaystyle t =18[/tex]

hence,

he bought 18 tacos

Find the area of the figure

Answers

Answer:

145.1327

Step-by-step explanation:

Divide the given figure up into two smaller figures. Calculate the area of each of the smaller figures and then add up the areas. One can divide this figure into a rectangle with sides (8 and 15), and a semi-circle with a diameter of (8m).

Calculate the area of the rectangle, the formula to calculate the area of a rectangle is ([tex]base*height[/tex])

8 * 15 = 120

Calculate the area of the semi-circle. The formulas for the area of a semi-circle is the formula for the area of a circle divided by (2), ([tex]A=\frac{(pi)r^2}{2}[/tex]). Where (A) represents the are, (pi) represents the number (3.1415...), and (r) represents the radius of the circle. The radius is always half of the diameter of a cricle. Substitute in the given values, and solve

[tex]\frac{(pi)(\frac{8}{2})^2}{2}[/tex]

[tex]=\frac{(pi)(4)^2}{2}[/tex]

[tex]=\frac{(pi)16}{2}[/tex]

[tex]=8(pi)[/tex]

~25.1327

Now add up the two values,

120 + 25.1327

= 145.1327

the length and the breadth of a rectangular Garden are 0.8 km and 0.6 km respectively find the length of a wire required to put a fivefold fans around the garden​

Answers

Answer:

Length of wire required for 5 fold of garden = 14 km

Step-by-step explanation:

Given:

Length of rectangle garden = 0.8 km

Width of rectangle garden = 0.6 km

Find:

Length of wire required for 5 fold of garden

Computation:

Perimeter of rectangle = 2[l + b]

Perimeter of garden = 2[0.8 + 0.6]

Perimeter of garden = 2[1.4]

Perimeter of garden = 2.8 km

Length of wire required for 5 fold of garden = 5 x Perimeter of garden

Length of wire required for 5 fold of garden = 5 x 2.8

Length of wire required for 5 fold of garden = 14 km

a set of speakers that regularly cost $160 are on clearance for 35% off. Find the sales price of the speakers

Answers

Answer:

I'm pretty sure this is the answer....

The speakers are $56.

Sorry if i'm wrong. :')

Step-by-step explanation:

Answer:

You want to buy something that costs $160, and it's on sale for 35% off. What is the item's sale price?

First, convert the 35% to a real mathematical number. For percents, this is always done by dividing the 35% by 100%, or 35% / 100% = 0.350.

Second, find out what 35% of $160 is. This is the amount of the sale discount. This is always found by mulitplying 0.350 by the item's cost $160, like this:

0.350 x $160 = $56.00.

So for this sale, you'll save $56.00 on this item.

This means, the cost of the item to you is

$160 - $56.00 = $104.00.

Alternatively, you can think about it this way. The item is 35% off. This means you'll pay 65.000% of the total cost (100% - 35% = 65.000%).

Now what's 65.000% of the total cost?

0.650 x $160 = $104.00.

Just like the result above, the sale price on the item is $104.00

Is this a function? please explain if possible.​

Answer:

Yes, it is a function.

Step-by-step explanation:

A function is a relation where each x-value (input value) has exactly one y-value (output value) that is related to it or mapped to it. In order words, in a function, an input value can only have one output value.

Thus, the relation represented by the table of values above is a function because every x-value (input value) has exactly one y-value (output value).

A sealed room in a hospital, measuring 5m wide, 10m long, and 3m high, is filled with pure oxygen.
One cubic meter volume of oxygen contains 1000L gas, and 22.4L of oxygen gas contains
6.02 x 1023 molecules (Avogadro's number).
A. 2.1976 x 100 molecules
B. 3.0051 x 1026 molecules
C. 4.0313 x 1027 molecules
D. 7.5014 x 1030 molecules​

Answers

Answer:

Option C. 4.0313×10²⁷ molecules.

Step-by-step explanation:

We'll begin by calculating the volume of oxygen in the room. This can be obtained by calculating the volume of the room since the gas will eventually fill the room.

Width (W) = 5 m

Length (L) = 10 m

Height (H) = 3 m

Volume (V) =?

V = L × W × H

V = 10 × 5 × 3

V = 150 m³

Thus, the volume of oxygen is 150 m³

Next, we shall convert 150 m³ to L. This can be obtained as follow:

1 m³ = 1000 L

Therefore,

150 m³ = 150 m³ × 1000 L / 1 m³

150 m³ = 150000 L

Finally, we shall determine the number of molecules of oxygen in the room. This can be obtained as follow:

22.4 L = 6.02×10²³ molecules

Therefore,

150000 L = 150000 × 6.02×10²³ / 22.4

150000 L = 4.0313×10²⁷ molecules

Thus, the number of molecules of oxygen in the room is 4.0313×10²⁷ molecules

Its says in question 4 tue horizontal translation is A right.?

Answers

Answer:

Here we have:

g(x) = 3*f( 2*x - 2) - 1

We want to know the horizontal translation used here.

We need to discuss two types of transformations here.

horizontal translation.

If we have a function f(x), a horizontal translation of N units is written as:

g(x) = f(x + N)

if N is negative, the translation is to the right.

if N is positive, the translation is to the left.

Horizontal dilation.

For a function f(x) an horizontal dilation of scale factor k is written as:

g(x) = f( x/k)

You can see that in our function we have both of these transformations.

Because we compare the translation with f(x), we assume that the horizontal translation is the first thing we did, then we must have

translation:

g(x) = f(x + N)

and now a horizontal dilation of scale factor k

g(x) = f( (x + N)/k)

Then we must have that the argument of the above function is the same as the argument of the given function.

(x + N)/k = 2*x - 2

then:

k = 1/2

(x + N)/1/2 = 2*x + 2*N = 2*x - 2

2*N = -2

N = -2/2 = -1

This means that we have a translation of 1 unit to the right.
