Answer:

9.9 hours, rounded to the nearest tenth hour.

Step-by-step explanation:

To calculate the time of travel, we must first divide the distance by the speed. Why, you ask? Because of this equation:

[tex]Speed\=\ \frac{distance}{time}[/tex]

Therefore, with a little bit of arrangement, we get:

[tex]Time\=\ \frac{distance}{speed}[/tex]

So, let's get on with it.

[tex]Time\=\ \frac{643 \ miles}{65 \ mph}[/tex]

[tex]Time\=\ 9.9 \ hours [/tex]

Finally, we have our answer: 9.9 hours, rounded to the nearest tenth.

Hope this helped!

Answer: 1 : 3

The red tiles will therefore form 75% of the whole pattern.

Ratio of Yellow tiles to Red tiles is;

25 : 75

Simplest form. Divide each side by 25;

15 times and more. After she pours the 15th container, in the middle of the next one, the work will be done.

Step-by-step explanation:

Length, Area, and Volume Scale Factors

If two similar shapes have a length scale factor of a:b, then the scale factor of their areas (or surface lateral areas) is [tex]a^2:b^2[/tex] and the scale factor of their volumes is [tex]a^3:b^3[/tex].

We are given the scale factor of the surface areas of two similar containers A and B as 4:25.

The length scale factor is

[tex]\sqrt{4}:\sqrt{25}=2:5[/tex]

The volume scale factor is: [tex]5^3:2^3[/tex] = 125:8 = 15.625

Warda needs to fill with oil and pour into container B 15.625 times to get container B full of oil.

Thus, after she pours the 15th container, in the middle of the next one, the work will be done

Answer: The discount price is $11.60. The discount is $46.40. (I didn't know which answer you wanted)

Step-by-step explanation: First, you need to find the discount. To do that, all you need to do is multiply 58 by 80/100 (this is still equal to 80%). You should get 46.40 (you might get 46.4 but it's the same thing), Then, subtract 46.40 form 58. You should get 11.60. So your final answer should be $11.60.

Answer:

( √15 + 8)/7

Step-by-step explanation:

TanA = -√15

.we are to find tan(A-π/4).

In trigonometry

Tan(A-B) = TanA - TanB/1+ tanAtanB

Hence:

tan(A-π/4) = TanA - Tanπ/4/1+ tanAtanπ/4

Substitute tan A value into the formula

tan(A-π/4) = -√15-tanπ/4 / 1+(-√15)(tanπ/4

tan(A-π/4) = -√15-1/1-√15

Rationalize

-√15-1/1-√15 × 1+√15/1+√15

= -√15-√225-1-√15/(1-√225)

= -2√15-15-1/1-15

= -2√15 -16/(-14)

= -2(√15+8)/-14

= √15 + 8/7

Hence the required value is ( √15 + 8)/7

Step-by-step explanation:

Answer:

A) 0

Step-by-step explanation:

hope this helps, pls mark brainliest :D

Answer:

a)First, solve and regroup

11=y-5x

y=11+5x.

Plug in:

6x-2(5x+11)=-6

6x-10x-22=-6

-4x-22=-6.

-4x=16

x=-4.

Plug it:

y=11+5(-4)

y=11-20

y=-9.

x,y=-4,-9.

b) The error Tim made is that he confused the x and y.

The correct answer is -4,-9.

He said it was -9,-4.

Hope this helps plz hit the crown ;D

The correct solution is -4,-9 time might have changed x coordinate with y-coordinate

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

6x-2y = -6...1

11= y-5x...2

(a) Rearranging the 2 equation;

11=y-5x

y=11+5x.

substituting in first equation;

6x-2(5x+11)=-6

6x-10x-22=-6

-4x-22=-6.

-4x=16

x=-4.

Now putting the value of x in second equation;

y=11+5(-4)

y=11-20

y=-9.

x,y=-4,-9.

(b) The error Tim made is; he confused the x and y.

The correct answer will be -4,-9.

Answer:

the median home size.

Step-by-step explanation:

In this scenario, the confounding variable would be the median home size. This is because this factor is both a cause and effect of the median home prices. A bigger house would obviously be worth more than a smaller house so the house size affects the prices of the homes in the market. At the same time, the median home sizes can also cause an increase or decrease in crime rates as criminals are more likely to target homes that seem as though they have more valuables inside.

Answer:

$6.3

Step-by-step explanation:

Given that:

There are 3 friends who have ordered some eatables.

Price of one pizza = $14

Price of two-liter soda bottle = $2.75

Price of a bag of chips = $2.15

The price of all the items is split evenly.

To find:

How much each person owes i.e. the amount of money each person will have to pay?

Solution:

First of all, let us find the total amount to be paid for all the three items.

Total amount to be paid = $14 + $2.75 + $2.15 = $18.9

Now, this total amount is evenly split i.e. equally divided in three parts.

Let us divide the total amount by 3.

Therefore, share of each friend = [tex]\frac{\$18.9}{3} = \bold{\$6.3}[/tex]

Answer:

What's your question you have having a problem?

Answer:

Step-by-step explanation:

Draw the graph of x = - y - 7.

Convert to the slope-intercept form (y = mx + b):

x = -y - 7      add y to both sides

x + y = -7     subtract x from both sides

y = -x - 7

This is the straight line equation. We only need two points to plot the graph.

Choose any value of x, put to the equation and calculate the value of y.

for x = 0:

y = -0 - 7 = -7 → (0, -7)

for x = -7:

y = -(-7) - 7 = 7 - 7 = 0 → (-7, 0)

Mark points in the coordinate system and draw a line.

The intersection points of the circle and the line are the solution.

Answer:

(-7, 0) and (0, -7)

Step-by-step explanation:

Draw the graph of x = - y - 7.

Convert to the slope-intercept form (y = mx + b):

x = -y - 7      add y to both sides

x + y = -7     subtract x from both sides

y = -x - 7

This is the straight line equation. We only need two points to plot the graph.

Choose any value of x, put to the equation and calculate the value of y.

for x = 0:

y = -0 - 7 = -7 → (0, -7)

for x = -7:

y = -(-7) - 7 = 7 - 7 = 0 → (-7, 0)

The intersection points of the circle and the line are the solution.
