Answer:

a) 9 miles

b) 6 miles

c) 3 miles

Step-by-step explanation:

a) Clare's speed = 12 mph

Calculate Clare's speed in miles per minute by dividing 12 by 60 (as there are 60 minutes in an hour):

12 ÷ 60 = 0.2 miles per minutes

Therefore, position after 45 minutes: 45 x 0.2 = 9 miles

b) Han's speed = 8 mph

Calculate Han's speed in miles per minute by dividing 8 by 60 (as there are 60 minutes in an hour):

8 ÷ 60 = 2/15 miles per minutes

Therefore, position after 45 minutes: 45 x 2/15 = 6 miles

c) Distance between Clare and Han = 9 - 6 = 3 miles

Find the equation of the circle with center (4, 4)

madam [21]

General equation of a circle is (x+a)^2 + (y+b)^2 = radius ^2
a and b are the centre and you put in the inverse so as x=-4, a=-4. same for b as the y-coordinate is positive, it becomes negative
the last part is the radius of the circles squared so just 7^2 = 49 !

Can someone please help me with this problem?

GenaCL600 [577]

You need to know and have memorized metric unit conversions. They are easy, you just need to know how many zeros to add.

1 cm = 10 mm
1 m = 1000 mm
1 m = 100 cm
1 km = 1000 m

(1.) 4m + 3cm = 400cm + 3cm = 403cm
(2.) 3km + 8m = 3000m + 8m = 3008m
(3.) 7cm + 9mm = 70mm + 9mm = 79mm
(4.) 1m + 5cm = 100cm + 5cm = 105cm
(5.) 5km + 5m = 5000m + 5m = 5005m

Do you see that to switch 5km to smaller unit meters you just add the zeros on to the end. Because 1km = 1000m ; 5km = 5000m

You try the rest. let me know if you have any questions.

Whats the answer to 8h+5-3h=8h-4 and how do i do it

tiny-mole [99]

The solution to the linear equation:

8h + 5 - 3h = 8h - 4

is h = 3.

<h3>How to solve the linear equation?</h3>

Here we have the linear equation:

8h + 5 - 3h = 8h - 4

To solve it, we need to move all the terms with h to the left side of the equation and the terms without x to the right side:

8h - 3h -8h = -4 - 5

-3h = -9

Now we can divide both sides by -3 to get:

h = -9/3 = 3

We conclude that the solution to the linear equation is h = 3.

At one company a level 1 engineer receives a salary of $45,000 and a level 2 receives a salary of $65,000. The company has a bud

kkurt [141]

Answer:

Company will hire 3 Engineers of Level 1 and 10 Engineers of level 2.

Step-by-step explanation:

Let the number of engineers for level 1 be x.

Let the number of engineers for level 2 be y.

Given:

Total Number of engineers company can hire = 13

Now Total number of engineers are equal to sum of number of engineers for level 1 and number of engineers for level 2.

Hence Framing in the equation form we get;

$x+y=13 \ \ \ \ equation\ 1$

Also Given:

Salary of level 1 engineers = $45,000

Salary of level 2 engineers = $65,000

Total Budget of Company = $785,000

But Total Budget of Company depends upon the sum of Salary of level 1 engineers multiplied with number of level 1 engineers and Salary of level 2 engineers multiplied with number of level 2 engineers.

Hence equation can be framed as;

$45000x+65000y = 785000$
