divide 450 in the ratio 2 is to 3 is to 5
Answer:
90 : 135 : 225
Step-by-step explanation:
sum the parts of the ratio, 2 + 3 + 5 = 10 parts
Divide the number by 10 to find the value of one part of the ratio
450 ÷ 10 = 45 ← value of 1 part of the ratio, then
2 parts = 2 × 45 = 90
3 parts = 3 × 45 = 135
5 parts = 5 × 45 = 225
Then
450 in the ratio 2 : 3 : 5 is 90 : 135 : 225

1. Dolores is on a bridge that is 42 feet above a lake. What is the distance from Dolores to the boat? G
Answer:
See answer below
Step-by-step explanation:
You are missing data such as the angle of the boat next to Dolores. I found an exercise similar to this, and I'm going to show it here and use the missing data to show you how to do it:
Dolores is on a bridge that is 45 feet above a lake. She sees a boat at a 30 degree angle of depression. What is Dolores' approximate horizontal distance from the boat?
According to that, I will use the angle of 30° to do this, but the distance of 42 feet.
Now, we can see this as a triangle. Dolores is on a bridge 42 feet above a lake, this 42 feet distance should be one side of the triangle (The vertical forming the 90° angle), and the boat that is on the lake, is seen with an angle of 30°. So the distance of the boat, to the spot where dolores is, under the bridge would be the horizontal side.
With this, we have the opposite side (a) and the adyacent side (b) of the triangle, and we have the angle, therefore:
tanα = a/b
Replacing we have:
tan30° = 42/b
b = 42 / tan30°
b = 72.75 feet
Hope this helps

NEED HELP A mine extracts 2 tons of ore in an hour. Of the total ore extracted in a day, 4 tons is purchased by the government and more than 10 tons is sold to a mineral extractor. If the mine operates for x hours in a day, what is the simplest inequality that represents the number of hours the mine must operate to meet its obligations?
A.
x > 3
B.
x > 4
C.
x > 5
D.
x > 7
Answer:
D. x > 7
Step-by-step explanation:
The mine operates x hours per day and extracts 2 tons of ore per hour.
The amount of ore extracted as a function of hours of operation is
2x
The mine must produce 4 tons plus more than 10 tons each day. The mine must produce more than 14 tons in one day. That means that 2x must be greater than 14.
2x > 14
Divide both sides by 2.
x > 7
Answer: D. x > 7
Ms. Brown bought 6 boxes of pencils with a total of 240 pencils. How many pencils were in each box?

In 3 hours, Jim can walk 14 miles. To find the time
he would take to walk 25 miles, he wrote the proportion 3/14= 25/h.
Explain his error.
Answer:
He should have used the proportion:
3/14=h/25
h=5.36 hours
Step-by-step explanation:
He should have used the proportion:
3/14=h/25
14h=3(25)
14h=75
h=5.36
Among two supplementary angles the measure of the larger angle is 400 more than the
measure of the smaller. Find their measures.
9514 1404 393
Answer:
70° and 110°
Step-by-step explanation:
The sum of angles is 180°; their difference is 40°. So, the larger is ...
(180° +40°)/2 = 110°
The smaller is 180° -110° = 70°
The two angles are 70° and 110°.
_____
Above, we have "cut to the chase." If you let the larger be 'a' and 's' and 'd' represent the sum and difference, you have ...
a + (a-d) = s . . . . the sum of the larger and smaller angles
2a = s+d . . . . . . add d
a = (s+d)/2 . . . . the relation we used.

represent
[tex] \frac{ - 7}{5} [/tex]
on the number line
Given:
The number is [tex]-\dfrac{7}{5}[/tex].
To find:
The location of the given number of the number line.
Solution:
We have,
[tex]Number=-\dfrac{7}{5}[/tex]
It can be written as
[tex]Number=-\dfrac{5+2}{5}[/tex]
[tex]Number=-\dfrac{5}{5}-\dfrac{2}{5}[/tex]
[tex]Number=-1-\dfrac{2}{5}[/tex]
It means the number is less than -1 but more than -2. So, the number lies between -2 and -1.
The mixed fraction form of given number is
[tex]Number=-(1+\dfrac{2}{5})[/tex]
[tex]Number=-(1\dfrac{2}{5})[/tex]
[tex]Number=-1\dfrac{2}{5}[/tex]
Divide the number in 5 equal parts between two consecutive integers.
Now each unit represents [tex]\dfrac{1}{5}[/tex].
Since [tex]Number=-1-\dfrac{2}{5}[/tex], therefore, it is 2 units left from -1.
The number line is given below.

Just need answer for both
Answer:
First one: 12 ft
Second one: 50ft^2
Step-by-step explanation:
Because both triangles are congruent, any value on one triangle is the same one on the other triangle so CBD= 12ft for the perimeter
Second one:
because both triangles are congruent like I stated above, both triangle are congruent.
But in this case we have to find the area of the whole rectangle.
What we do here is multiply 25 by 2
or
add 25+25
our answer is 50ft^2
Which equation represents the total cost of a repair by an electrician after x hours?
An electrician charges $90 per hour plus a $50 travelling fee.
Answer:
y = 90x + 50
Step-by-step explanation:
In this situation, let's define the variable and the constant.
The variable is what changes, so in this case the wage ($90) changes with how many hours the electrician is hired for.
The constant is the number that stays the same, in this case it would be the $50 traveling fee because it remains the same every time.
The equation should be written in this form:
y = mx + b
m = slope (variable)
b = y-intercept (constant)
Therefore, you can write the equation like this:
y = 90x + 50
