In questions 1-5, help the developer name the streets if the entrance street is y=2/3x-7, by using the patterns you discovered i

n the opening activity and the chart you filled in for the closing questions. All the streets that run parallel to the entrance street ( Oak Street) were given tree names, while all those that run perpendicular to the entrance street were given flower names. If it is neither parallel nor perpendicular to the main street, then the street was labeled with an animal name.
1. Street equation: y=-3/2x-2
weeping willow street
hibiscus street
oak street
Panther street

2.Street equation: y=2/3x+4
weeping willow street
hibiscus street
oak street
gray squirrel

3. Street equation: y=8/12x-7
silver maple street
hibiscus street
oak street
raccoon street

4. Street equation: y=-2/3x-16
elm street
daffodil street
oak street
panther street

5. Street Equation: y=4/6 x+5/3
elm street
camilla street
oak street

A) If volume of a cylinder is 4817 and the radius is 4, find the height.
Diano4ka-milaya [45]

Answer:

71. 8

Step-by-step explanation:

volume of a cylinder = 4/ 3 π r² h

=> 4817 = 4/ 3 × 22/ 7 × 4² × h

=> h = (4817 × 3 × 7)/ (4 × 22 × 4²)

=> h = 71.8

Can someone please help me with 3,4,5,6 pleaseeee!
FromTheMoon [43]

Answer:

3) m∠E = 102°

4) m∠V = 41°

5) x = 9

6) m∠J = 77°

Step-by-step explanation:

3) Find m∠E:

∠DFE and ∠GFH are opposite angles, so they have equal measures.

Now you know have 3 expressions for the angle measures of ΔGFH

Write an equation and solve for x:

(10x + 3) + (13x - 5) + 90 = 180

combine like terms:

23x + 88 = 180

subtract 88:

23x = 92

divide by 23:

x = 4°

Now that you have the value of x, you can evaluate both expressions given for ΔDFE:

6(4) + 11 = 35°

10(4) + 3 = 43°

Solve for the missing angle:

35 + 43 + m∠E = 180

m∠E + 78 = 180

m∠E = 102°

4) Find m∠V

ΔRST is an equilateral triangle (all sides are equal)

An equilateral triangle has 3 equal angles:

180 ÷ 3 = 60°

∠STR and ∠UTV are supplementary (add up to 180°):

m∠STR + m∠UTV = 180

m∠UTV + 60 = 180

∠UTV = 120°

Now that you have this angle, you can calculate the value of x:

120 + (5x + 6) + (4x - 9) = 180

9x + 117 = 180

9x = 63

x = 7

Now you can calculate the measure of ∠V

m∠V = 5(7) + 6 = 41°

5) Find the value of x

ΔPQR is an isosceles triangle (2 sides are equal)

In an isosceles triangle, the base angles are congruent.

Write an equation and solve for x:

29 + 29 + (8x - 14) = 180

8x + 44 = 180

8x = 136

x = 17

6) Find m∠J

Same as the last one, base angles are congruent.

Write an equation and solve for x:

(8x + 5) + (8x + 5) + (5x - 19) = 180

21x - 9 = 180

21x = 189

x = 9

Calculate the measure of ∠J:

m∠J = 8(9) + 5 = 77°
