a=bcd
a+b=cd
a+b+c=d
a+b+c+d=1
Answer:
a=1/2,b=-1,c=-1 and d=1/2
Am I right please?
Answer:
a = 1/42; b = 1/7; c = 1/3; d = 1/2
Step-by-step explanation:
a = bcd
a + b = cd
a + b + c = d
a + b + c + d = 1
d + d = 1
2d = 1
d = 1/2
2a = bc
2a + 2b = c
2a + 2b + 2c = 1
bc + 2b = c
bc + 2b - c = 0
bc + 2b + 2c = 1
-3c = -1
c = 1/3
a + b = cd
a + b = 1/6
a = bcd
a = b(1/3)(1/2)
a = 1/6 b
1/6 b + b = 1/6
7/6 b = 1/6
b = 6/42
b = 1/7
a = 1/6 b
a = 1/6 * 1/7
a = 1/42
if 2x+20 and 3x+20 makes a straight angke find value of x
Answer:
x = 28
Step-by-step explanation:
The sum of the angles in a straight angle = 180°
Sum the angles and equate to 180
2x + 20 + 3x + 20 = 180
5x + 40 = 180 ( subtract 40 from both sides )
5x = 140 ( divide both sides by 5 )
x = 28

B. (x+9)^2+(y−2)^2=3
C. (x−9)^2+(y+2)^2=3
D. (x−2)^2+(y+9)^2=9
Answer:
(x-2)^2 + (y+9)^2 = 9
Step-by-step explanation:
The equation of a circle is given by
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x-2)^2 + (y--9)^2 = 3^2
(x-2)^2 + (y+9)^2 = 9

Enter your answer in the box.
Answer:
∠ V = 58°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
∠ WYX = 180° - (52 + 24)° = 180° - 76° = 104°
∠ VYU = ∠ WYX = 104° ( vertically opposite angles )
Then
∠ V = 180° - (104 + 18)° = 180° - 122° = 58°

A recipe requires 500 mL of milk. You will make the recipe once a month for the next 4 months. You do not use milk other than for cooking. Which container of milk should you buy? (1L=1000 mL) *
Answer:
2L
Step-by-step explanation:
Each recipe = 500 mL of milk
Number of times you make recipe per month = 1
Number of months you make recipe = 4
Total milk used for 4 months = 500 mL * 1 * 4
= 2000 mL
Recall,
1L = 1000 mL
Therefore,
2000 mL = 2L
You should buy 2L container of milk

2. Your school building casts a shadow 25 feet long. You are 6 feet tall and cast a shadow 18 inches long. Find the height of the school building in feet
Answer:
Height of school building = 100 feet
Step-by-step explanation:
Given;
Shadow of school building = 25 feet
Height of individual = 6 feet
Shadow of individual = 18 inches = 1.5 feet
Find:
Height of school building
Computation:
Height of individual / Shadow of individual = Height of school building / Shadow of school building
6 / 1.5 = Height of school building / 25
Height of school building = 25 x 4
Height of school building = 100 feet
Myles has calculated that 1/2 a box of tile will cover 1/6 of his kitchen floor. How many boxes of tile will he need to cover the entire kitchen?
Answer: He need 3 boxes.
Step-by-step explanation:
Every 1/6 of his floor needs 1/2 of the tile box.Split his floor into 6 parts, each part needing 1/2 of the tile box:
[tex]6*\frac{1}{2} =\frac{6}{2} =3[/tex]
Or you can add 1/2 six times for each 1/6 of the floor:
[tex]\frac{1}{2} +\frac{1}{2} +\frac{1}{2} +\frac{1}{2} +\frac{1}{2} +\frac{1}{2} =\frac{6}{2}=3[/tex]
