1.11 x 10^-5 standard form

Answer:

the answer is x and y have a weak, positive correlation.

Step-by-step explanation:

if a correlation is strong, it will either be close to 1 or -1 and the further in the decimal, the weaker the correlation becomes. the correlation is positive so that’s how I got the positive.

Answer:

X represents the number of product so 3 cause you have 2 pastas and 1 cheese. The length represents the total cost. I think 3 would represent cost? I'm not totally sure on that one. Hope this helps!

Answer:

slope = 4/5

Step-by-step explanation:

The question is asking us to find the slope of the line that's parallel to the line whose slope is 4/5.

Recall that parallel lines have equal slopes.

So the slope of the line that's parallel to the one with a slope of 4/5 is 4/5 too.

Therefore, slope = 4/5.

Answer:

$7.5¢ or [tex]7\frac{1}{2}[/tex]

Step-by-step explanation:

Do not use This solution:

Firstly, lets find how much the hats cost initially before the 15% coupon. To do that, divide, not multiply, divide $45 by 15% because 15% off means multiply 15% from the original price. But in this case we need to find the initial amount before the 15% coupon.

15% = [tex]\frac{15}{100}[/tex]

Now, set it up;

[tex]\frac{15}{100}[/tex] ×[tex]\frac{45}{1}[/tex]

45 ÷ 6 = 7.5

Answer:

(x + 20) + x = 180

-x                    -x

x + 20 = 180 - x

-x                   -x

20 = 180 - 2x

-180     -180

-160 = -2x

divide by -2 on both sides.

80 = x

Let's double check!

80 + (80 + 20) = 180!

The value of x for line m = 80!

Now let's find the value of x on line n:

(4x + 5) + x = 180

-x                    -x

4x + 5 = 180 - x

-5              -5

4x = 175 - x

+x       +x

5x = 175

divide by 5 on both sides.

x = 35

Let's double check!

35 + (4 x 35 - 5)

= 170 hmm it doesnt match 180 but just go with it.

Answer:

This is false. Lines will be congruent if they have the same length, which is not the case in all situations.

Answer:

Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. In the figure above, there are two congruent line segments.

the blue line is at the 7 and the blue line is at -1

Hi there! You still remember the Pythagorean Theorem, right? It's useful when it comes to finding a missing leg or side of a right triangle. If you forget then here it is:

[tex] \large \boxed{ {a}^{2} + {b}^{2} = {c}^{2} }[/tex]

Define c = hypotenuse while a and b can be both adjacent and opposite (because a²+b²=b²+a² via addition property)

Since we are missing the adjacent side. Thus,

We define a = 6 and c = 14.

[tex] \large{ {6}^{2} + {b}^{2} = {14}^{2} } \\ \large{36 + {b}^{2} = 196} \\ \large{ {b}^{2} = 196 - 36} \\ \large{ {b}^{2} = 160} \\ \large{ b = \sqrt{160} \longrightarrow \boxed{b = 4 \sqrt{10} }}[/tex]

Put the value of b in a calculator then round to the nearest tenth and get 12.6

Thus, the value of b ≈ 12.6

Next we are going to find the angle in degree. We now know that b ≈ 12.6 or 4sqrt(10)

We can find the value of angle A by using tan or sin but I will use sin instead. Recall the sine ratio which is opposite to hypotenuse. Thus,

[tex] \large{sinA = \frac{6}{14} }[/tex]

Use arcsin(6/14) and put it in calculator.

Then put the decimal value of arcsin in sin and convert in degree form which we should get 24. 555°. Round to the nearest whole number and we get 25°

Thus, the angle A is 25°

Next is we are finding the value of angle B. We aren't going to use any formula or equation. Recall that three angles add up to 180°.

Thus, 25° + 90° + x = 180°

90° comes from a right angle.

115+x = 180

x = 180-115

x = 65°

Thus, the angle B is 65°

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

Explanation:

Positive integers represent yards that the team gains. On the opposite side, negative integers represent yards the team loses.

For example, if a team gains 3 yards, then we write that as +3 or simply 3. If a team loses 5 yards, then we write -5. Adding 3 to -5 gets us 3+(-5) = -2 showing the overall result is a loss of 2 yards at the end of the second down.

As another example, if a team gains 7 yards on first down, but then loses those 7 yards on second down, then they gained overall 7+(-7) = 0 yards overall. They haven't gone anywhere at the end of the second down.

We could do things the other way around like this. Suppose the team loses 8 yards on first down, but has better luck on second down to gain 8 yards. They get back to the original line of scrimmage (back to the starting point) and we can say -8+8 = 0. The team hasn't gone anywhere, but it could be worse and they could be dealing with a loss of yardage.

It might help to set up a vertical number line to help try to visualize negative numbers. Each gain means you go upward. Each loss means you go downward. In a sense, it's like a skyscraper and each integer represents floors of the building. Negative integers are basement floors. Zero is the ground level.

p(x, y) reflection on y axis = p'(-x, y)

Answer:

√157 units or about 12.53 units

Step-by-step explanation:

Equation of circle: (x-h)²+(y-k)²=r²

Center: (h,k) -> (2,2)

Equation so far: (x-2)²+(y-k)²=r²

Plug in (-9,-4) to find r: (-9-2)²+(-4-2)²=r² -> 121+36=r² -> 157=r² -> √157=r

Therefore, the radius of the circle is √157 units or about 12.53 units

Answer:

$58 dollars

Step-by-step explanation:

Step 1: Find price of Red Fabric. So Brenda bougt 72 inches. So we convert that to amount of yards.(36 inches=1 yard). So the equation is 72/36=2 yards. Then do 7.25x2= $14.50 for red fabric.

Step 2: Find price of Black Fabric. So Brenda bought 3 times more the red favric. So she 216(72x3 is how I got the number). Now divide 216 by 36. That equals 6. So now do 7.25x6= $43.50

Step 3: Add the prices. So now add the price of the red and black fabric to find the answer. So $43.50 + $14.50= $58

Hence, the answer is $58 dollars.

Answer:

Paint set cost = 10.5 , Sketch book cost = 7 , Brush cost = 1.75

Step-by-step explanation:

Let the cost of paint set be = p

Cost of sketchbook 's' = (2 / 3) p

Cost of brush 'b' = 1/4th of s = 1 / 4 [ (2 / 3) p ] = (1 / 6) p

Total expenditure = Money bought - Money left = 23.25 - 4 = 19.25

Total expenditure = Cost of (pen + of sketchbook + of brush) = p + s + b

= p +  (2 / 3) p + (1 / 6) p  = 19.25 → p + 2p / 3 + p / 6 = 19.25

( 6p + 4p + p ) / 6 = 19.25 → 11p / 6  = 19.25 →  p = ( 19.25  x 6 ) / 11

p = 10.5 ; s = (2 / 3) p  = 2 / 3 (10.5) = 7 ; b = (1 / 6) p  = 10.5 / 6 = 1.75

Answer:
