Answer:
The equation that best represents the line that is parallel to 3x - 4y = 7 and passes through the point (-4, -2) is y = 3/4x + 1.
Step-by-step explanation:
3x - 4y = 7 and (-4, -2)
First, solve for y in the equation:
3x - 4y = 7
-4y = -3x + 7
4y = 3x - 7
y = 3/4x - 7/4
m = 3/4 (This will be the slope of the parallel line.) and (-4, -2)
Use the point-slope equation to find the equation that will best represent a parallel line:
y − y1 = m(x − x1)
y - -2 = 3/4(x - -4)
y + 2 = 3/4x + 3 (the 4s cancel out)
(3/4 x 4/1 = 3)
y = 3/4x + 1
The graph that I attached is what these two equations would look like graphed. I am not sure what you mean by two options, I'm sorry!
Which of the following should have been the proportion that the student wrote?
answer choices:
a) AD/AB=AB/AC
b) AD/AC=AB/AB
c) AB/AD=AB/AC
d) AB/AC=AB/AD
Answer:
Therefore the choice is
a) AD/AB=AB/AC
Step-by-step explanation:
In Δ ADB and Δ ABC
∠A ≅ ∠A …………..{Reflexive Property}
∠ ADB ≅ ∠ ABC ..............{ measure of each angle is 90° given }
Δ ADB ~ Δ ABC ….{Angle-Angle Similarity test}
If two triangles are similar then their sides are in proportion.
Therefore the choice is
a) AD/AB=AB/AC

Step-by-step explanation:
347.2 cm3
351.9 cm3
359.1 cm
372.4 cm
Answer:
Volume = 351.9cm³
Step-by-step explanation:
Volume of cylinder = πr²h
r = 4cm, h = 7cm, π = 3.142, volume = 347.2cm³
Volume = 3.142 × 4² × 7
Volume = 3.142 × 16 × 7
Volume = 351.90cm³
Volume = 351.9cm³
I hope this was helpful, please mark as brainliest
Answer:
B) 351.9 cm3
Step-by-step explanation:
351.9 cm3
V = πr2h
V = π(4)2(7)
V = π(16)(7)
V = 112π
V = 351.858
Answer:
1/96
Step-by-step explanation:
scale is
a model cannot be as same size as that of actual object ,
hence objects are scales down to some value so that its model can be comfortably made.
scale is generally ratio of length of drawing and actual length of object
scale = length of drawing / actual length of object.
Given
length of classroom drawing = 5in
actual length of classroom = 40 ft
as unit of drawing and actual classroom is different lets make unit of class smilar to that of drawing that is in inches
we know
1 feet = 12 inches
thus 40 feet = 12*40 inches = 480 inches
thus,
actual length of classroom in inches = 480 inches
scale used by Carla = length of drawing / actual length of classroom
= 5 inches/480 inches = 1/96 (answer)
