number 20 ............​

Answer:

5+2=7

Step-by-step explanation:

Step-by-step explanation:

Since Sara and friends ate 60% of the container of cookies, it means that they ate 60% of 40 cookies.

∴

How many cookies Sara and Friends ate = total × (percentage of cookie ate)

                                                                    = 40 × 0.60

                                                                    = 24

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°

h= $3.50

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

Answer:

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

Your Answer is B, D, F

perimeter of non-shaded part = 7

perimeter of shaded part = 9

so ratio of shaded to non shaded is =

shaded:non shaded = 9:7 = 9/7

so option b is correct

Answer:

I think it's 9/7 for the nonshaded one and the shaded one is 81/49

Answer:

24

x-18=24

x=24+18

x=42

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.

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

Answer:

The first, second, third, and fourth

Step-by-step explanation:

Each input in the first, second, third, and fourth only have one output. In the fifth one 3.3 and 6.6 are seen twice as the x-value, so this is incorrect.

Cada entrada en la primera, segunda, tercera y cuarta tiene solo una salida. En el quinto, 3.3 y 6.6 se ven dos veces como el valor de x, por lo que esto es incorrecto.
