Answer:

15m+80 would be the correct equation

Answer:

15*m=(530-80)

Step-by-step explanation:

30$ per lawn. 530-80=450. This gives us how much money he still needs to buy his gulf clubs. But, the question says that Carlos can earn the rest of the money ($450) by mowing 15 lawns.

Here's how we model that as an expression:

15m=(530-80)

15 lawns for m dollars would get him 530-80 (450) or the remaining amount.

ummmmm i think apple?

Step-by-step explanation:

because if 4 equals green and you put the square root of branch in there you will get branch×apple tree+water=apple my bad its green apple

i did it wrong i just redid the question and found the right answer. so if you put branch×square root of 9 apples+apple tree=9 apples right? well yes but if you add branch+square root of 4 more apples you will get in total 13 apples.

The third term of the given sequence exists 19.

Term to term rule when the sequence [tex]$-2,1,19 \ldots .$[/tex] is reversed will be [tex]$\frac{a-13}{6}$[/tex].

The sequence exists in a particular order in which connected things follow each other.

The term-to-term rule of the sequence stands 6a+13, where a stands for the first term First-term a = -2

Second term b will be [tex]$-2*6+13=1$[/tex]

The rule for the third term will be 6b+13, where b will be the second term. So the third term will be [tex]$6* 1+13=19$[/tex]

So, the sequence will be [tex]$-2,1,19 \ldots \ldots . .$[/tex]

If the order of the above sequence stands reversed, the new sequence will be [tex]$19,1,-2 \ldots \ldots .$[/tex]

If we subtract 13 from first term 19 and then divide by 6 we will get 1 which stands for the second term of the new sequence [tex]$19,1,-2 \ldots \ldots .$[/tex]

So a new term-to-term sequence rule will be [tex]$\frac{a-13}{6}$[/tex] where a stands for the first term.

Therefore, the third term of the given sequence exists 19.

Term to term rule when the sequence [tex]$-2,1,19 \ldots .$[/tex]  exists reversed will be [tex]$\frac{a-13}{6}$[/tex].

Step-by-step explanation:

since there is no explanation whether the rest of the sweets are orange or not, the probabilty of it is 1-0.8=0.2 or less

Answer:

[tex]\huge\boxed{Answer\hookleftarrow}[/tex]

Assuming that there are only 2 flavors of the sweet ⇻ strawberry & orange.

____________________

P (strawberry flavored sweet) = 0.8

P (orange flavored sweet) = ?

Now, we know that ➳ the value of probability ≤ 1. So, the probability of orange flavored sweets is less than 1.

So,

P (orange flavored sweet) = 1 - P (strawberry flavored sweet)

C)

Step-by-step explanation:

3/4 · 12 = 9

Answer:D.5

Step-by-step explanation:

Let's first take a look at our x here. --- (x + 2)^2

Because we are adding a two to our x, this means that we are shifting our graph 2 to the left. Remember that with functions, it's always the opposite!

There is nothing attached to the y, so we are not moving our function up or down.

And then the radius of our circle. Remember that the equation requires us to square this value (... = r^2), so we need to take the square root of 4. The square root of 4 is 2.

With this information, let's now look at our options.

Option A - INCORRECT, the radius is too large

Option B - INCORRECT, this was shifted 2 units to the right

Option C - INCORRECT, the radius is too large

Option D - CORRECT, the radius is 2 and the circle was shifted 2 units to the left

Hope this helps!! :)

Answer:

D

Step-by-step explanation:

The equation for a circle is

(x-h)^2 + (y-k)^2 = r^2

where (h,k) is the center and r is the radius

(x+2)^2 + (y)^2 = 4

Rewritng

(x- -2)^2 + (y-0)^2 = 2^2

The center is at ( -2,0) and the radius is 2

C and D are the only circles with a center at (-2,0)

B,D are the only circles with radius 2

Answer:

x ≈ 6.2

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + 17.1² = 18.2²

x² + 292.41 = 331.24 ( subtract 292.41 from both sides )

x² = 38.83 ( take the square root of both sides )

x = [tex]\sqrt{38.83}[/tex] ≈ 6.2 ( to the nearest tenth )

Answer:

money earned = 110

Step-by-step explanation:

Money earned * percent saved = money saved

Change to decimal form

money earned * .30 = 33

Divide each side by .3

money earned = 33/.3

money earned = 110

Answer:

82 degrees is the answer

Step-by-step explanation:

angle 6 and 7 are adjacent angles and adjacent angles add up to 180 deg. thus

angle 7 = 180 - 98 = 82 deg

The measure of ∠6 and ∠7 are on a straight line. This means there sum is equals to 180 degrees. Therefore, the measure of ∠7 is 82 degrees.

The sum of angle on a straight line is 180 degrees. This simply means the total angle on a straight line is 180 degrees.

∠6 = 98 degrees

Therefore,

∠6 + ∠7 = 180°(angles on a straight line)

∠6 = 98 degrees

Hence,

98 + ∠7 = 180

subtract 98 from both sides

98 - 98 + ∠7 = 180 - 98

∠7 = 82 degrees.

Answer:

30m x 40m

Step-by-step explanation:

The diagram is 15cm x 20cm

since 1cm = 2m

the backyard measures

30m x 40m

Answer:  The backyard is 30 meters by 40 meters

30 meters = horizontal dimension

40 meters = vertical dimension

===========================================================

Explanation:

The pool on paper is 7.5 units across horizontally. Applying the scale factor, we can see that it corresponds to 7.5*2 = 15 meters

The 20 meter portion is vertical. On paper, we see that it's 10 units tall. So the "times 2" operation applies to jump from 10 cm to 20 meters

Or you could note that the ratio 1 cm : 2 m scales up to 10 cm : 20 m after multiplying both parts by 10.

-----------------

With that in mind, all we need to do really is count the number of squares across the top and along the left side. Across the top, we have 15 squares. That 15 cm corresponds to 15*2 = 30 meters in length.

Along the left side, the figure is 20 cm tall. So that corresponds to 20*2 = 40 meters.

The backyard is 30 meters by 40 meters. This includes the backyard, shed, and other features in the diagram. The entire backyard is 30*20 = 600 square meters. If you wanted to know the area of the grass only, then you'd subtract off the areas of the pool, shed, etc.

-----------------

Your teacher mentions that the pool is similar to the backyard overall. Since we're in a geometry setting, the word "similar" is very specific of course.

We can match up the corresponding lengths to form a proportion like so

(large horizontal)/(small horizontal) = (large vertical)/(small vertical)

30/15 = 40/20

2 = 2

So that confirms we have similar figures, at least in terms of the sides being proportional. Everything being a rectangle helps show that all angles are the same.
