Answer: approximately 105.7°C

Step-by-step explanation:

Seawater of 35 psu has a specific heat of 0.932 compared with 1.000 for pure water. Pure water freezes at 0 °C and boils at 100 °C (212 °F) under normal pressure conditions. When salt is added, the freezing point is lowered and the boiling point is raised. Therefore, we can tell that salt increases the boiling temperature, but not by very much. If you add 3 grams of salt to 100 grams (or mL) of water, instead of boiling at 100° C, it'll boil at 100.5° C.

And I'm not sure about the ocean water because the expected range is too wide and various, so maybe I guess the boiling point of salty ocean water would be about 105.7°C?

Answer:

J(-5,3) K(-1,-2) L(3,4)

Step-by-step explanation:

Reflections over the y axis make the x its opposite. 5 would change to -5, 1 would change to -1, and -3 would change to 3.

When a shape is reflected, it must be reflected across a line.

See attachment for the graph of the image of JKL

The coordinates are given as:

[tex]\mathbf{J = (5,3)}[/tex]

[tex]\mathbf{K = (1,-2)}[/tex]

[tex]\mathbf{L = (-3,4)}[/tex]

The rule of reflection across the y-axis is:

[tex]\mathbf{(x,y) \to (-x,y)}[/tex]

So, the image of the reflection is:

[tex]\mathbf{J'= (-5,3)}[/tex]

[tex]\mathbf{K'= (-1,-2)}[/tex]

[tex]\mathbf{L'= (3,4)}[/tex]

Answer:

Step-by-step explanation:

What are the two closest square numbers to 73?

64 and 81

[tex]\sqrt{64} \leq \sqrt{73} \leq \sqrt{81}\\8\leq \sqrt{73} \leq 9\\8*9 = 72[/tex]

Answer:

72

Step-by-step explanation:

Since $73$ is between $64=8^{2}$ and $81=9^{2}$, we know that $\sqrt{73}$ is between $8$ and $9.$ Our answer is $8\cdot9=\boxed{72}.$

Answer:

2 periods

Step-by-step explanation:

Simple interest is compounded one time, usually annually, although it could be less time or longer. Thus I answer 2 periods. If your choices include 2 years, that is most likely the answer.

To find the answer,

$10,000 x .03 = $300.

$600 / $300 = 2 periods.

Hope this helps.

Answer:

No, I haven't taken the isat.

Answer:

No, what is it for?

Step-by-step explanation:

PART A:

Finding the slope of the function f(x)

Choose any two pairs of coordinate from the table; (-1, -15) and (0, -10)

Let (-1, -15) be (x₁, y₁) and (0, -10) be (x₂, y₂)

Slope =

Slope of f(x) = 5

The function g(x) is given in the straight line equation form

Where,  is the slope and  is the y-intercept

Slope of g(x) = 2

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

g(x) = 2x + 8

Where, the slope (m) = 2 and the y-intercept (c) = 8

The y-intercept of g(x)  is 8

for f(x), we can read the y-intercept when x = 0.

From the table, when x = 0, y = -10

The y-intercept of f(x) is -10

Function g(x) has higher y-intercept

Step-by-step explanation:

Question: 1

Jessica = $8

Ciara = $12 + 4 $16

Now we times both values.

16 x 8 = $128

8 x 16 = $128

They would both need to work 8 hours ft=or the same money.

Question 2:

$8 x 5 = $40

$16 x 5 =$80

Jessica will be less expensive.

Answer: 3 hours

Jessica=$8

Ciara= $4 + $12

8*3= $24

4*3= $12 +$12= $24

Because Ciara has an additional $12 fee, you have you add it on to her total.

Answer:

One

Step-by-step explanation:

A parallel line has the same slope of the original graph. Because of this, all we need to do is put the equation you gave into slop-intercept form, or:

y = mx + b

Don't forget that m is the slope, and b is the y-intercept!

3x - 3y = 45

-3y = -3x + 45

y = x + 15

Compare this to the equation of the slope-intercept form and look for m:

y = mx + b

There's nothing in front of the variable! No worries, that's the same thing as saying 1x.

But mathematicians are a little lazy (lol) and they don't want to mistake the number 1 for the lowercase letter L or a capital i. Because of that, they made 1x equal x.

Long story short, the slope for the equation (3x – 3y = -45) is one. And because parallel lines have the same slope as their original counterparts, the slope is one as well!

I recommend trying a few other problems like these. You'll end up using them a lot in the future!

Good luck and keep studying!

Answer:

[tex]13x^{2}[/tex]-20x+8

Step-by-step explanation:

Step 1: rearrange the equation

16x^2 - 3x^2 - 7x - 13x +8

Step 2: solve the equation

16x^2 - 3x^2 = 13x^2

-7x - 13x = -20x

(the +8 will stay the same)

so when we put it all together it gives us

13x^2 - 20x + 8

Answer/Step-by-sep explanation:

1. Given:

∆NMK ≅ ∆TRP

[tex] \overline{NM} = 20 [/tex]

[tex] \overline{MK} = 15 [/tex]

[tex] \overline{KN} = 25 [/tex]

[tex] \overline{TR} = 3x - 1 [/tex]

a. To complete the congruent statement, thus: ∆MNK ≅ ∆RTP

b. The side that is congruent to [tex] \overline{TR} [/tex] is [tex] \overline{NM} [/tex]. Thus:

[tex] \overline{TR} [/tex] ≅ [tex] \overline{NM} [/tex]

c. Since [tex] \overline{TR} [/tex] ≅ [tex] \overline{NM} [/tex], therefore:

[tex] \overline{TR} = \overline{NM} [/tex]

[tex] 3x - 1 = 20 [/tex] (substitution)

Add 1 to both sides

[tex] 3x = 20 + 1 [/tex]

[tex] 3x = 21 [/tex]

Divide both sides by 3

[tex] x = \frac{21}{3} [/tex]

[tex] x = 7 [/tex]

2. a. Slope of LK = [tex] \frac{rise}{run} = \frac{4}{3} [/tex]

Slope of LM = [tex] \frac{rise}{run} = -\frac{3}{5} [/tex]

b. ✍️Length of LK is the distance between L(-7, 4) and (-4, 8):

[tex] Lk = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

[tex] Lk = \sqrt{(-4 -(-7))^2 + (8 - 4)^2} [/tex]

[tex] Lk = \sqrt{(3)^2 + (4)^2} [/tex]

[tex] Lk = \sqrt{9 + 16} [/tex]

[tex] Lk = \sqrt{25} [/tex]

[tex] Lk = 5 [/tex]

✍️Length of LM is the distance between L(-7, 4) and (-2, 1):

[tex] LM = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

[tex] LM = \sqrt{(-2 -(-7))^2 + (1 - 4)^2} [/tex]

[tex] LM = \sqrt{(5)^2 + (-3)^2} [/tex]

[tex] LM = \sqrt{25 + 9} [/tex]

[tex] LM = \sqrt{34} [/tex]

[tex] LM = 5.8 [/tex] (nearest tenth)

∆KLM is not an isosceles ∆ because it does not has two equal side lengths. This we can see because LK and LM are not equal.

Therefore, Anthony is incorrect. Am isosceles ∆ has two equal sides.

Answer:

The minimum sample size required is 1068.

Step-by-step explanation:

The complete question is:

A researcher wishes to​ estimate, with 95​%  confidence, the population proportion of adults who eat fast food four to six times per week. Her estimate must be accurate within 3​%  of the population proportion.

​No preliminary estimate is available. Find the minimum sample size needed.

Solution:

The (1 - α)% confidence interval for the population proportion is:

[tex]CI=\hat p\pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

The margin of error for this interval is:

[tex]MOE= z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

The information provided is:

[tex]MOE=0.03\\\text{Confidence level}=95\%[/tex]

Assume that the sample proportion is 50%.

The critical value of z is, 1.96.

Compute the minimum sample size required as follows:

[tex]MOE= z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

      [tex]n=[\frac{z_{\alpha/2}\cdot \sqrt{\hat p(1-\hat p)}}{MOE}]^{2}[/tex]

         [tex]=[\frac{1.96\times\sqrt{0.50(1-0.50)}}{0.03}]^{2}\\\\=1067.1111\\\\\approx 1068[/tex]

Thus, the minimum sample size required is 1068.

Answer:

second quadrant

Step-by-step explanation:

(x, y ) → (x - 5, y + 3 ) means subtract 3 from the original x- coordinate and add 3 to the original y- coordinate.

(- 3, - 2 ) ← in third quadrant

→ (- 3 - 5, - 2 + 3) → (- 8, 1 ) ← in second quadrant

Answer: 1.67 feet in 1 second

Step-by-step explanation: To find out how far the penguin walked in 1 second, you’ll have to divide 10 by 6 or use the ratio 10 : 6 and divide. You should get a final answer or result of 1.67 feet in 1 second.

*Tip: If you want to make sure your answer is correct, simply multiply your answer times 6, and see if it equals to 10 or is near 10.

Answer:

5/3 ft

Step-by-step explanation:

10 ft = 6s

x ft = 1s

cross multiply

10ft × 1s = 6s × x

{divide both sides by The coefficient of x (6x) }

(10 ft × s) ÷ 6s= x

10 ft ÷ 6 = x

5/3 ft = x

x = 5/3 ft
