En total, Juan gastó $205.25. 1 kilo de queso cuesta $90. 1/2 kilo de jamón cuesta $60. Si comprara un kilo de tortilla, un kilo de pepino y un kilo de jamón, Juan gastaría $129. Si Juan tiene $430, puede comprar 3 kilos de jamón, 1 kilo de queso, 5 kilos de pepino y 1 2/3 de tortillas.

Dado que Juan compró 1/4 de pepino que cuesta $3, 1 1/2 de jamón que cuesta $120, 1/3 de tortillas que cuesta $6 y 4/8 de queso que cuesta $45, para determinar cuánto dinero gastó en total, cuánto cuesta un kilo de queso, cuánto cuesta medio kilo de jamón, cuánto gastaría si comprara un kilo de tortilla, un kilo de pepino, y un kilo de jamón y, si Juan tiene $430, qué puede comprar sin que le sobre ni un peso, se deben realizar los siguientes cálculos:

Answer:

y=1(x-5)^2+3

Please correct me if i am wrong.

Step-by-step explanation:

We know that the turning point of a graph in the form a(x+p)^2+q is (-p,q) so,

TP(5,3) means that p=-5, q=3.

To solve a for the function y = a(x-5)^2+3, we can substitute one of the points we know lie on the graph for x and y so,

Substitute (8,12) into y=a(x-5)^2+3,

12=a(8-5)^2+3

12=9a+3

9=9a

a=1,

So substitute in a,

y=1(x-5)^2+3

The distance, in feet, between the ground and the top of the ladder is 8 feet.

The diagram formed will be a right triangle having the hypotenuse, adjacent and opposite sides

To get the  distance, in feet, between the ground and the top of the ladder, we will use the Pythagoras theorem as shown:

Given the following sides

Substitute the given parameters into the formula to have:

10² = opp² + 6²

opp²=100 - 36

opp² = 64

opp = 8feet

Hence the distance, in feet, between the ground and the top of the ladder is 8 feet.

Answer:

y = 70°

z = 40°

Step-by-step explanation:

The two red marks in the sides HF and HG of the triangle means that it is an isosceles triangle, and it means that it have the two angles in the base with the same value, so the angle y have to be 70°. Now, the sum of the 3 internal angles of a triangle is always 180°. We have two angles with 70, so 70+70= 140°. 180-140 = 40°

Answer:

m∠EFD = 90°

m∠EHF = 127°

m∠HFG = 56°

m∠G = 71°

m∠E = 19°

Step-by-step explanation:

From inspection of the given diagram, line segment GD is a straight line and m∠EFG=  90°.  

Angles on a straight line sum to 180°:

⇒ m∠EFG + m∠EFD = 180°

⇒ 90° + m∠EFD = 180°

⇒ 90° + m∠EFD - 90° = 180° - 90°

⇒ m∠EFD = 90°

Angles on a straight line sum to 180°:

⇒ m∠EHF + m∠FHG = 180°

⇒ m∠EHF + 53° = 180°

⇒ m∠EHF + 53° - 53° = 180° - 53°

⇒ m∠EHF = 127°

From inspection of the given diagram, m∠EFH and m∠HFG form a right angle:

⇒ m∠EFH + m∠HFG = 90°

⇒ 34° + m∠HFG = 90°

⇒ 34° + m∠HFG - 34° = 90° - 34°

⇒ m∠HFG = 56°

Interior angles of a triangle sum to 180°:

⇒ m∠HFG + m∠GHF + m∠G = 180°

⇒ 56° + 53° + m∠G = 180°

⇒ 109° + m∠G = 180°

⇒ 109° + m∠G - 109° = 180° - 109°

⇒ m∠G = 71°

Interior angles of a triangle sum to 180°:

⇒ m∠E + m∠EFH + m∠EHF = 180°

⇒ m∠E + 34° + 127° = 180°

⇒ m∠E + 161° = 180°

⇒ m∠E + 161° - 161° = 180° - 161°

⇒ m∠E = 19°

Answer:

5y = 45.00; y = $9.00

Step-by-step explanation:

Step-by-step explanation:

as there are only 3 types of discontinuity overall : A, B and C.

there is no fourth, so D is out.

to check we use x = 2 in both equations and see, if and how the 2 connect or disconnect at that point.

5x + 4, x = 2

5×2 + 4 = 14

this is finite and a well-defined number.

2 - x, x = 2

2 - 2 = 0

this is again finite and well-defined.

but it is different from 14 above.

there is no multiplication factor or so that causes special values. so, there is no removable discontinuity. A is out.

none of the values at the point go to infinity, so there is no infinite discontinuity. B is out.

but yes, the functional value Suendenbock suddenly jumps at the point from 0 to 14 without any connection.

so, yes, it is a jump. C is right.

8$ per hour

Step-by-step explanation

First, we need to find how many hours Naomi worked, total.

Simply add [tex]2.5+4.25=6.75[/tex]

Now we know that Naomi earned 54$ over 6.75 hours.

All we have to do to find the hourly rate is divide [tex]54/6.75=8[/tex]

Naomi earns 8$ per hour mowing lawns.

Answer:

$8

Step-by-step explanation:

Set up an equation with the payrate ($/hr) as the unknown.

2.5 × R + 4.25 × R = 54

6.75 × R = 54 ; R = [tex]\frac{54}{6.75}[/tex] = 8

Answer:

48, 28 respectively

Step-by-step explanation:

You would find the pattern for both.

1) 42, 43, 45, ?, 52

the pattern is +1, +2, +3, +4

42 + 1 = 43 +2 = 45 + 3 = 48 + 4 = 52

42, 43, 45, 48, 52

2) 23, ?, 33, 38, 43

the pattern is to add 5

23 + 5 = 28 + 5 = 33 + 5 = 38 + 5 = 43

23, 28, 33, 38, 43

Answer:

A  angles are 15 and 75    B.  angles are 30 and 60     C.  angles are 36 and 54

Step-by-step explanation:

Remember that the two acute angles of a right triangle = 90

A  one angle = x ; the other angle = 60 + x     so  60 +x + x = 90

 60 + 2x = 90; 2x = 30;  x = 15  one angles; the other angle is 60 + 15 = 75

B.   One angle = x ; the other angle = 2x     so  x + 2x = 90

     3x = 90 ; x = 30 one angle;    the other angle s 2x = 2(30) = 60  

C    2 : 3 means 2x:3x

       One angle = 2x ; the other angle = 3x ;  so  2x + 3x = 90

       5x = 90;  x = 18  this is what x is equal to.  Now the find the angles:

       one angle is 2x meaning 2(18) = 36 and the other angle is 3x meaning              3(18) = 54.    

To check this answer one angle to the other angle is represented by the ratio 2:3;   36:54 = 2:3   Reduced!  

Answer:

Millie is 11. Molly is 8.

Step-by-step explanation:

Step 1: Subtract 3 from 19. The reason why you do this is to make sure that you don't have an extra 3 lying in there for the next few steps.

19-3=16

Step 2: Divide 2 from 16. You do this because there are two sisters.

16÷2=8

8 will then become Molly's age

Step 3: Add 3 to 8. This will give you Millie's age because she is 3 years older than Molly.

3+8=11

In conclusion, Millie is 11 and Molly is 8.

Answer:

Step-by-step explanation:

3x + 4y = 24

Find the x intercept by solving intersecting the graph of f(x) or y with

y=0 (which is the x-axis)

4y= -3x+24, subtract 3x from both sides of the equation

y = (-3x/4) +6, divide both sides by 4

if y=0 then  

(-3x/4) +6 = 0  , subtract 6 from both sides

-3x/4 = -6, multiply both sides by 4

-3x = -24 , divide both sides by

x= 8, so the x intercept is at (8, 0)

the general formula of a line is y=mx+b , where b is the y-intercept

since our equation is y = (-3x/4) +6 then y intercept is at (0, 6)

Answer:

22)43300000, 23)~7, 24)~20

Step-by-step explanation:

22)6.48*10^(7)-(2.15*10^(7))=4.33*10^7 (or 43300000)

23)2.95*10^6=2950000, 2.15*10^7=21500000, 21500000/2950000=~7

24)1.3*10^9=130000000, 1300000000/64800000=~20

Answer:

Step-by-step explanation:

22.  You can write these exponents out if it makes it easier to understand, then convert back into exponential form.

6.48 x 10⁷ = 64800000 France

2.15  x 10⁷ = 21500000  Australia

Subtracting Australia from France = 43300000

Converting back to exponential  would be 4.33 x 10⁷

But if you notice both number have the exponent of 10⁷.  Since these are both the same, you can just subtract the whole number for Australia from the number for France  6.48 - 2.15 = 4.33

then just put the exponent on the end.  4.33 x 10⁷

23.  Again it might be easier to convert to standard numbers first.

Area of Australia = 2.95 x 10⁶  or 2950000

Population = 2.15 x 10⁷  or 21500000

So population per square mile would be population divided by area.

21500000 / 2950000 = 7.3 people per square mile

Now if you look at the two numbers, the exponents are only different by 1.  You can easily make the population have the same exponent as the area by moving the decimal place of the whole number

Population 2.15 x 10⁷ is the exact same as 21.5 x 10⁶.  Now since both number have the same exponents, you can cancel those out and just divide the whole numbers.   21.5 divided by 2.95 which also equals 7.3.

24. You can look at this the same way.

China population 1.3 x 10⁹  is 1300000000

France population 6.48 x 10⁷ is 64800000

Dividing China by France you get about 20.1 which means China is about 20.1 times great in population than France.

If you use the same method as in question 23, you can change the population of China so the exponent matches that of France.

1.3 x 10⁹ is exactly the same as 130 x 10⁷

Again, since both exponents are the same, you can cancel them out and just divide the whole numbers.

130 / 6.48 which also equals about 20.1
