Find the equation of the linear function represented by the table below in slope-
intercept form.

Answer:

1/5

Step-by-step explanation:

[tex]5^{-x}= 25\\\\5^{0.5x) = (5^{-x})^{-0.5}\\\\=(25)^{-0.5}\\\\=(25)^{\frac{-1}{2}}\\\\=(\sqrt{25})^{-1}\\\\=5^{-1}\\\\= \frac{1}{5}[/tex]

Answer:

19

Step-by-step explanation:

Answer:

38 multiplied by 50/100 equals 19

Step-by-step explanation:

just multiply 38 and 50 then over 100 and divide then you should get 19

Answer:

Please check the explanation.

Step-by-step explanation:

Given that the measures of the Angles of the triangle ΔXYZ are in the ratio 2:4:6.

Also, the sum of the measure of angles in a triangle is 180°.

so

2x + 4x + 6x = 180

Add similar elements: 2x + 4x + 6x = 12x

12x = 180

Divide both sides by 12

12x/12 = 180/12

Simplify

x = 15

Therefore, the measure of the angles of a triangle will be:

2x = 2(15) = 30

4x = 4(15) = 60

6x = 6(15) = 90

Verification:

30 + 60 + 90 = 180

180 = 180

Step-by-step explanation:

C is the answer

Answer:

There's an infinite number of possible answers because there might be any multiplication of 3 for boys and any multiplication of 2 for girls. So, for example:

There might be 3 boys and 2 girls.

There might be 6 boys and 4 girls.

There might be 9 boys and 6 girls.

There might be 12 boys and 8 girls.

etc...

In each case the ratio stays the same - 3 : 2.

Of course there probably can't be more than a few dozens of people in one class, but theoretically we can raise the numbers up to infinite.

Step-by-step explanation:

Answer: The height of the palm tree is 21 feet.

Step-by-step explanation:

We can use a ratio to solve this:

Actual height to shadow for both objects. The fraction equivalents must be equal.

6/8 = x/28 . Cross multiply

6(28) = 8x

168 = 8x   Divide both sides by 8  (8's "cancel" on the right)

168/8 =8x/8

21 = x . This gives us the tree's height as 21 feet.

Another way to solve this is to use the ratios, but simplify the first fraction

6/8 = 3/4

Then multiply the length of the shadow by 3/4

3/4 × 28 = height

28÷4 = 7    7 × 3 = 21

21  feet= the height of the palm tree.

Answer:

what subject is this for

Step-by-step explanation:

Answer:

sin²θ

Step-by-step explanation:

Using the trigonometric identities

sin²x + cos²x = 1 ⇒ cos²x = 1 - sin²x

cotx = [tex]\frac{cosx}{sinx}[/tex]

Given

[tex]\frac{1-sin^20}{cot^20}[/tex]

= [tex]\frac{cos^20}{\frac{cos^20}{sin^20} }[/tex]

= cos²θ × [tex]\frac{sin^20}{cos^20}[/tex] ( cancel the cos²θ )

= sin²θ

Answer:

Just add the painted miles

2 1/6 + 1 2/3

=3 5/6

then we subtact the total miles that wanna be painted which is 6

6 - 3 5/6

=2 1/6

The answer B

The Answer is 4 meters per second

Answer:

4

Step-by-step explanation:

You want to take the farthest coordinates ( 16/4 ), the closest coordinates to 0 ( 4/1 ), and then subtract to get 12m/3s, then divide 12m by 3s to get 4m/s.

Remember to solve for Slope is SUBTRACTING then dividing.

Answer:

x² + y² is equal to = (4 / 81)(845m² + 78m + 18)

Step-by-step explanation:

We first need to get the values of x and y, which can be done using a system of equations, substituting one of the two functions into the other:

Given:

y = 2x + 2

3x + 3y = 26m

Then:

3x + 3(2x + 2) = 26m

3x + 6x + 6 = 26m

9x + 6 = 26m

9x = 26m - 6

x = (26m - 6) / 9

Now we can solve for y:

y = 2x + 2

y = 2(26m - 6) / 9 + 2

y = 2(26m - 6) / 9 + 18 / 9

y = (52m - 12 + 18) / 9

y = (52m + 6) / 9

Now we can sum up their squares:

x² + y²

= ((26m - 6) / 9)² + ((52m + 6) / 9)²

= (676m² - 312m + 36) / 81 + (2704m² + 624m + 36) / 81

= (3380m² + 312m + 72) / 81

= (4 / 81)(845m² + 78m + 18)

please try to correct the the question.because the second function is a constant function.i mean it has an answer but it is not found in the match.

Answer:C

Step-by-step explanation:

keeping proportional and thats the only answer where the difference is still $2.25

Answer:

Correct choice: B

Step-by-step explanation:

Proportions

The ice cream shop sold small ice creams for $1.25 each and large ice creams for $3.75 each.

This summer the prices will be raised at the same proportion. If x is the new price for small ice creams and y is the new price for large ice creams, then it should be satisfied:

[tex]\frac{1.25}{x}=\frac{3.75}{y}[/tex]

Let's test each option:

A.

[tex]\frac{1.25}{2.50}=0.5[/tex]

[tex]\frac{3.75}{5.00}=0.75[/tex]

B.

[tex]\frac{1.25}{1.50}=0.83[/tex]

[tex]\frac{3.75}{4.50}=0.83[/tex]

C.

[tex]\frac{1.25}{2.00}=0.625[/tex]

[tex]\frac{3.75}{4.25}=0.88[/tex]

D.

[tex]\frac{1.25}{1.80}=0.694[/tex]

[tex]\frac{3.75}{7.20}=0.52[/tex]

Correct choice: B

Answer:

No

No

Step-by-step explanation:

In a right angled triangle :

The square of the length of the longest side is equal to the sum of the squares of the two remaining sides : - Pythagoras

That is :

a² = b² + c² (condition must be satisfied).

9m, 4m, 5m

9² = 4² + 5²

81 = 16 + 25

81 ≠ 41 (not right angled)

5cm, 12cm, 14cm

14² = 12² + 5²

196 = 144 + 25

196 ≠ 169 (not right angled)

Answer:

13/20

Step-by-step explanation:

Probability is the ratio of the number of possible outcome to the number of total outcome.

Given that for the past 60 days, on 39 of those days she arrived at work before 8 AM while for the rest of those days she arrived after 8:30 AM, the probability that she will arrive at 8 AM on the next day she goes to work

= 39/60

= 13/20

In decimal, this will be expressed as 0.65 and 65% in percentage.

Answer:

a. 80%

b. £34

c. £340

Step-by-step explanation:

a. We are given that Mrs Trent spent 20% of her weekly wage on food. This means she would have 80% of her weekly wage left with her.

b. 10% of Mrs Trent weekly wage:

If 20% = £68

10% = (10*68)/20 = £34

c. Let x represent weekly wage of Mrs Trent

Given that she spends £68 of x (weekly wage) on food, which is 20% of x.

This means that, 20% of x = £68

Let's find her weekly wage, x:

[tex] \frac{20}{100} * x = 68 [/tex]

[tex] 0.2x = 68 [/tex]

Divide both sides by 0.2

x = 340

Her weekly wage is £340.

Answer:

a) 80%

b) £34

c) £340

Step-by-step explanation:

A -

100% - 20% = 80%

B -

68 = 20%

34 = 10%

c -

34 = 10%

340 = 100%

as you times both sides by 10
