Answer:
28 decrease
Step-by-step explanation:
2,500 - 1,800 = 700
700/2500 x 100 = 28
So its 28% decrease.

In BCD, H is the centroid. If DE=51 find HE.
Answer:
[tex]HE=17[/tex] units.
Step-by-step explanation:
In a triangle, centroid is the intersecting point of the medians.
Centroid divides each of the medians in ratio [tex]2:1[/tex]
So,
[tex]\frac{DH}{HE}=\frac{2}{1} \\\\\frac{DH}{HE}+1=\frac{2}{1}+1\\\\ \frac{DH+HE}{HE} =3\\\\\frac{DE}{HE}=3[/tex]
Put [tex]DE=51[/tex] units
[tex]\frac{51}{HE}=3\\\\HE=\frac{51}{3}[/tex]
[tex]HE=17[/tex] units.
A ski slope is 320 yards long with a vertical drop of 100 yards. Find the
angle of elevation of the ski run. Round to the nearest degree.
Answer:
18°
Step-by-step explanation:
A ski slope is 320 yards long with a vertical drop of 100 yards. Find the
angle of elevation of the ski run. Round to the nearest degree.
The formula for angle of elevation is given as:
sin θ =Opposite/ Hypotenuse
Opposite = Vertical drop = 100 yards
Hypotenuse = Ski slope = 320 yards.
Angle of elevation =
sin θ = 100/320
sin θ = 0.3125
θ = arc sin(0.3125)
= 18.209956864°
Approximately = 18°

Answer:
$65.02
Step-by-step explanation:
15% of 85 = 12.75
sale price = 85-12.75 = 72.25
10% of 72.25 = 7.225 = 7.23
final cost = 72.25 - 7.23 = 65.02

£330 is divided between Henry, Gavin & Jim so that Henry gets twice as much as Gavin, and Gavin gets three times as much as Jim. How much does Gavin get?
Answer: Gavin gets $99
Step-by-step explanation:
Step 1
LET amount gotten by Jim be =x
amount gotten by Gavin be = 3x
amount gotten by Henry be = 2 x 3x = 6x
Such that the total amount shared by the three of them can be expressed as
x+ 3x + 6x = 330
Step 2
x+ 3x + 6x = 330
10x= 330
x= 330/10
x = 33
Jim gets $33
Gavin gets 3x= 3x 33= $99
Henry gets 6x= 6x 33= $198

Find the value of x in the triangle shown below.
Answer:
58
Step-by-step explanation:
Since two of the sides are both 6.2, we know that this is an isosceles triangle. Thus, the two angles opposite of x are both equal (61 degrees).
The angles inside of a triangle always add up to 180, so now we have
180 = 61 + 61 + x
Solving for x, we get x = 180 - (61 + 61) = 180 - 122 = 58
The lengths of two sides of a triangle are given.
Find the range of possible lengths for the third side. 17 cm and 12 cm
Answer:
Range = 5 - 29
Step-by-step explanation:
a + b > c
a+c > b
c+b > a
so
17+ 12 > c ,,,,,,,,,,,,,,,,,,,,,,,,,,,, so it should be lesser than 17+12 which is 29
17 +c > 12 ,,,,,,,,,,,,,,,,,,,,,,,,, and it should be greater than 17- 12 = 5
c+12 > 17 ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, same here, it should be greater than 17- 12 = 5
So the range is ,
17 + 12
to
17-12
whcih is - (5 to 29)
I hope I am right!!!

Janice used 1/3 yard of ribbon to tie a package and 1/6 yard of ribbon to tie a bow. How many yards of ribbon did Janice use? Is it 9/18? Which is 1/2? Sorry I really can't help her. I can help Sean with algebra no problem
Answer:
1/2 yard of ribbon
Step-by-step explanation:
Janice used 1/3 yard of ribbon to tie a package and 1/6 yard of ribbon to tie a bow. How many yards of ribbon did Janice use?
The number of yards that Janice used is calculated as:
1/3 yard + 1/6 yard
Lowest Common Denominator = 6
2 + 1/6
= 3/6
= 1/2 yard of ribbon
Janice used 1/2 yard of ribbon

Find mZA. The diagram is not to scale.
96°
118°
159
104°
Answer:
A=73
Step-by-step explanation:
sum of interior angles is (n-2)*180
5 sides, so (5-2)*180 = 3x180=540
sum of current interior angles (118+96+115+104)=433
subtract 540-433=107
This is NOT "A", this is your final interior measurement.
To get "A", take 180-107=73
A=73 degrees

Kris has 3 daughters who all live in different cities across Georgia. She wants to live somewhere that is an equal distance from each of her daughters. She mapped out the 3 cities and drew a triangle connecting them. How can she find a point on the map that is an equal distance from all 3 cities?
construct the incenter
construct the orthocenter
estimate the best place
construct the circumcenter
===========================================================
Explanation:
Consider triangle ABC. The vertex points are at A,B,C. These represent the three cities in which the three different daughters live. Constructing the circumcenter will produce a circle such that all three points A,B,C are on that circle. Let's say that D is the center of that circle.
This means that AD, BD, CD are all radii of this same circle. Radii of the same circle are the same length, which is why point D is equally distant from A,B,C. If the mother lives at point D, then she will travel the same distance to visit any three of her daughters. See the note below.
To construct the circumcenter, we form perpendicular bisectors to segments AB, BC and AC. Technically you only need two of them. All three of these perpendicular bisectors intersect at point D.

Note: Keep in mind that roads aren't completely straight, so that means we'll have to factor in the curvature of each road. But to keep things simple, we assume each road is a straight line segment.

A projectile is thrown upward so that its distance above the ground after t seconds is h=-121t^2 +504t. After how many seconds does it reach it maximum height?
Answer:
2.08secs
Step-by-step explanation:
Given the equation modeled by the height as h=-121t^2 +504t
The velocity of the object at the max height is zero, hence;
v = dh/dt = 0
dh/dt = -2(121)t + 504
dh/dt = -242t + 504
0 = -242t + 504
242t = 504
t = 504/242
t = 2.08secs
Hence the projectile reaches its maximum height after 2.08secs
Last week, the price of apples at a grocery store was $1.60 per pound. This week, apples at the same grocery store are on sale at a 10% discount. What is the total price of 4 1/2 pounds of apples this week at the grocery store?
Answer:
6.48 dollars total,
Step-by-step explanation:
First, you would want to multiply the amount of money per pound, by the amount of pounds. 1.60 multiplied by 4 1/2 or 4.5, would equal to 7.2 dollars. In order to find 10% of 7.2, your would need to multiply 7.2 by 0.10, which would give you 0.72. Then you would subtract 7.2 by 0.72 to get 6.48. So your answer would be 6.48 dollars. Hoped this helped.
