GEW has angle measures given by m/_G=5x + 66, m?/_ E = 3x, and m/_ W= 142 -4x whats the mesure of e
Answer:
21°
Step-by-step explanation:
GEW has angle measures given by m/_G=5x + 66, m?/_ E = 3x, and m/_ W= 142 -4x whats the mesure of e
= 5x + 66 + 3x + 142 - 4x = 180
4x + 208 = 180
4x = 208 - 180
4x = 28
x = 28/4
x = 7
Solving for E = 3x
E = 3 × 7
E = 21°

Calculate the slope of the passing line through each pair of points: (8, 6) and (-1, 6)
Answer:
[tex]\displaystyle m=0[/tex]

Slope Formula: [tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]Step-by-step explanation:
Step 1: Define
Point (8, 6)
Point (-1, 6)
Step 2: Find slope m
Simply plug in the 2 coordinates into the slope formula to find slope m

Answer:
Actual distance is 4500 cm (45 m).
Step-by-step explanation:
A scale is a representative fraction that can be used to either increase or decrease proportionally the dimension of a given object.
scale = [tex]\frac{distance on map}{actual distance}[/tex]
It is in the form of a ratio.
From the question, Distance on map = 4.5 cm,
scale = 1 : 1000
= [tex]\frac{1}{1000}[/tex]
scale = [tex]\frac{distance on map}{actual distance}[/tex]
Let the actual distance be represented by d.
So that,
[tex]\frac{1}{1000}[/tex] = [tex]\frac{4.5}{d}[/tex]
⇒ d = 4.5 x 1000
= 4500
d = 4500
The actual distance is 4500 cm (45 m).

The marked price of a water cooler is $ 4650. The shopkeeper offers an off-season discount of 18% on it. Find its selling price.
Answer:
3813
Step-by-step explanation:
M.P of water cooler=$4650
Discount% on water cooler=18%
Discount on water cooler=18/100*$4650 i.e.$837
So,selling price=$4650-$837i.e.$3813 Ans.
Answer:
3813
Step-by-step explanation:
the formula will be 18 upon 100 multiply by 4560. the answer is 837. now subtract the original price from the discount. 4560-837 is 3813 which is ur answer.
The equation P = 21 + 2w can be used to find the perimeter of a rectangle. A 1 point rectangular shaped playground is enclosed by a fence that is 500 m. The length of the playground is 120 m. Use the equation to determine the width of the playground *
Answer:
130 mStep-by-step explanation:
Given:
P = 2l + 2wP = 500 mLength is:
l = 120 mSubstitute values and solve for w:
500 = 2*120 + 2w2w = 500 - 2402w = 260w = 260/2w = 130 mThey found that in some people, this activity was reduced when the subjects participated in a
