Ann increased the quantities of all the ingredients in a recipe by 60% 60, percent. She used 808080 grams (g) of cheese. How much cheese did the recipe require?
Answer:
50 gram
Step-by-step explanation:
The actual percentage recipe = 100%
Percentage Increase in recipe = 60%
Recipe used as a result of increment = 80 gram
Hence,
100% + 60% = 80
160% = 80g
If :
160% = 80
100% = x
Cross multiply
1.6x = 80 * 1
1.6x = 80
x = 80 / 1.6
x = 50
Recipe required 50 gram

Answer:
Step-by-step explanation:
10). m(arc AB) = m(arc BC) = m(arc CA) [given in the picture]
m(arc AB) = [tex]\frac{360^0}{3}[/tex]
= 120°
Therefore, m(arc ACB) = m(arc AC) + m(arc BC)
= 120° + 120°
= 240°
11). m(arc CD) = 127° [Given]
m(arc AB) = 51° [Given]
m(arc AC) = m(arc BD) [Given]
m(arc CD) + m(arc BD) + m(arc AB) + m(arc AC) = 360°
127° + 2[m(arc BD)] + 51° = 360°
178° + 2[m(arc BD)] = 360°
2[m(arc BD)] = 360° - 178°
m(arc BD) = 91°
Since, m(arc CDB) = m(arc CD) + m(arc BD)
Therefore, m(arc CDB) = 127°+ 91°
= 218°
12). m(arc EH) + m(arc ED) + m(arc DH) = 360°
180° + 53° + m(arc DH) =360°
m(arc DH) = 360° - 233°
m(arc DH) = 127°

To find a(n) area of a triangle, all you need to do is use the triangle shape to make a rectangle and then calculate the area of the rectangle and divide it by the number of triangles you used to make the triangle.
for your triangle I can imagine it needs four triangles to make a rectangle.
unless you want to multiply 1/2x6x11 to get your answer.
hope this helped !

Answer:
[tex]\sf 1)\:4x - 2 > 2x + 8[/tex]
Add 2 from both sides:
[tex]\sf 4x-2+2>2x+8+2[/tex]
[tex]\sf 4x>2x+10[/tex]
Subtract 2x from both sides:
[tex]\sf 4x-2x>2x+10-2x[/tex]
[tex]\sf 2x>10[/tex]
Divide both sides by 2:

[tex]\boxed{\sf x>5}[/tex]
_______________________________
[tex]\sf 2)\: -3x - 6 > 4x - 20[/tex]
Add 6 from both sides:

[tex]\sf -3x>4x-14[/tex]
Subtract 4x from both sides:
[tex]\sf -3x-4x>4x-14-4x[/tex]
[tex]\sf -7x>-14[/tex]
Multiply both sides by -1:
[tex]\sf\left(-7x\right)\left(-1\right)<\left(-14\right)\left(-1\right)[/tex]
[tex]\sf 7x<14[/tex]
Divide both sides by 7:
[tex]\sf \cfrac{7x}{7}<\cfrac{14}{7}[/tex]
[tex]\boxed{\sf x<2}[/tex]

[tex]\sf 4x<3x-6[/tex]
Subtract 3x from both sides:
[tex]\sf 4x-3x<3x-6-3x[/tex]
[tex]\boxed{\sf x<-6}[/tex]
_______________________________
[tex]\sf 4)\: 2x + 3 + x < -2x + 1 + 12[/tex]
Combine like terms:
[tex]\sf (2x+x)= 3x[/tex]
[tex]\sf( 1+12)=13[/tex]
[tex]\sf 3x+3<-2x+13[/tex]
Subtract 3 from both sides:
[tex]\sf 3x+3-3<-2x+13-3[/tex]
[tex]\sf 3x<-2x+10[/tex]
Add 2x from both sides:
[tex]\sf 3x+2x<-2x+10+2x[/tex]
[tex]\sf 5x<10[/tex]
Divide both sides by 5:
[tex]\sf \cfrac{5x}{5}<\cfrac{10}{5}[/tex]
[tex]\boxed{\sf x<2}[/tex]

Apply distributive property:
[tex]\sf 2x-2>-x+4[/tex]
Add 2 from both sides:
[tex]\sf 2x-2+2>-x+4+2[/tex]
[tex]\sf 2x>-x+6[/tex]
Add x from both sides:
[tex]\sf 2x+x>-x+6+x[/tex]
[tex]\sf 3x>6[/tex]
Divide both sides by 3:

Combine like terms:
[tex]\sf (8x-2x)=6x[/tex]
[tex]\sf 4x-7<6x[/tex]
Add 7 from both sides:
[tex]\sf 4x-7+7<6x+7[/tex]
[tex]\sf 4x<6x+7[/tex]
Subtract 6x from both sides:

[tex]\sf 2x>-7[/tex]
Divide both sides by 2:
[tex]\sf \cfrac{2x}{2}>\cfrac{-7}{2}[/tex]

Upon descent, an airplane is 20,000 feet above the ground. The air traffic control tower is 200 feet tall. It is determined that the angle of elevation from the top of the tower to the plane is 15°. To the nearest mile, find the ground distance from the airplane to the tower.
Answer:
Base length of plane from control tower = 73,880 feet (Approx.)
Step-by-step explanation:
Given:
Height of plane from ground = 20,000 feet
Height of control tower = 200 feet
Angle of elevation from control tower = 15°
Find:
Base length of plane from control tower
Computation:
Height of plane from control tower = 20,000 - 200
Height of plane from control tower = 19,800 feet
Tan θ = Perpendicular / Base
Tan15 = 19,800 / Base length of plane from control tower
0.268 = 19,800 / Base length of plane from control tower
Base length of plane from control tower = 73,880 feet (Approx.)

4. Find an equation of the line that is tangent to the graph of 4x + 2xy^2 +44 = y^3 at the point (-3,2).
i need this asap.
Given:
The equation is:
[tex]4x+2xy^2+44=y^3[/tex]
To find:
The equation of the tangent on the given equation at point (-3,2).
Solution:
We have,
[tex]4x+2xy^2+44=y^3[/tex]
Differentiate with respect to x.
[tex]4(1)+2[x(2yy')+y^2(1)]+0=3y^2y'[/tex]
[tex]4+4xyy'+2y^2=3y^2y'[/tex]
[tex]4+2y^2=3y^2y'-4xyy'[/tex]
[tex]4+2y^2=(3y^2-4xy)y'[/tex]
Isolate y'.
[tex]\dfrac{4+2y^2}{3y^2-4xy}=y'[/tex]
Now, we need to find the value of the derivative at point (-3,2).
[tex]y'_{(-3,2)}=\dfrac{4+2(2)^2}{3(2)^2-4(-3)(2)}[/tex]
[tex]y'_{(-3,2)}=\dfrac{4+8}{12+24}[/tex]
[tex]y'_{(-3,2)}=\dfrac{12}{36}[/tex]
[tex]y'_{(-3,2)}=\dfrac{1}{3}[/tex]
It means the slope of the tangent line is [tex]\dfrac{1}{3}[/tex].
The equation of tangent line that passes through the point (-3,2) with slope [tex]\dfrac{1}{3}[/tex] is:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-2=\dfrac{1}{3}(x-(-3))[/tex]
[tex]y-2=\dfrac{1}{3}x+1[/tex]
[tex]y=\dfrac{1}{3}x+1+2[/tex]
[tex]y=\dfrac{1}{3}x+3[/tex]
Therefore, the equation of tangent line is [tex]y=\dfrac{1}{3}x+3[/tex].
find the area of ABCD
trapezoid ABCD ~ trapezoid EFGH
trapezoid ABCD: 20cm
trapezoid EFGH: 5cm
area of EFGH = 40 sq cm
Answer:
640 cm²
Step-by-step explanation:
The ratio of the area of 2 similar polygons = the ratio of the square of their corresponding lengths
Thus:
Area of Trapezoid ABCD to Area of Trapezoid EFGH = AB² to EF²
Area of Trapezoid ABCD = ? = x
Area of Trapezoid EFGH = 40 cm²
AB = 20 cm
EF = 5 cm
Substitute
x:40 = 20²:5²
x/40 = 400/25
x/40 = 16
Cross multiply
x = 16*40
x = 640
Area of trapezoid ABCD = 640 cm²

Anita has ₹130. She spent ₹25 on transportation, got ₹125 from a friend, bought fruits for ₹82 and received ₹75 from her mother. Calculate the money she has now.
Answer:
223.
Step-by-step explanation:
Money in hand = 130
Spent on transportation = 25
Received from friend = 125
Spent on fruits = 82
Received from mother = 75
So, Current money in hand = Money in hand - Spent on transportation + Received from friend - Spent on fruits + Received from mother
= 130 - 25 + 125 - 82 + 75
= 223
Hence, she has now 223.
