Guina made a scale drawing of a window she is making for her house.
1 centimeter = 3 inches. Triangle A B C. Side A is 4 centimeters, side B is 3 centimeters, and side C is 5 centimeters.
Which proportion could Guina use to find the length of side B?
StartFraction 1 centimeters over 3 inches EndFraction = StartFraction 3 centimeters over x centimeters EndFraction
StartFraction 3 centimeters over 1 centimeter EndFraction = StartFraction x centimeters over 3 centimeters EndFraction
StartFraction 1 centimeter over 3 inches EndFraction = StartFraction 3 centimeters over x inches EndFraction
StartFraction 3 inches over 3 centimeters EndFraction = StartFraction x inches over 1 centimeter
Answer:
Proportion: 1/3=3/x
Step-by-step explanation:
The "1/3" proportion is telling us how the scale measurement relates to the real measurement.
The "3/x" describes the length of side B.
Now it is easy to figure out the answer! :D

Brianna wants to buy a digital camera for a photography class. One store offers the camera for $49 down
and a payment plan of $20 per month. The payment plan for a second store is described by y - 15x + 79,
where y is the total cost in dollars and x is the number of months. Which camera is cheaper when the
camera is paid off in 12 months? Complete the explanation.
Answer:
Step-by-step explanation:
Cost of the camera at one store,
Down payment = $49
Per month payment = $20
Duration of the payment = 12 months
Total payment to be done = down payment + payments to be done in 12 months
= 49 + (20×12)
= 49 + 240
= $289
Cost of the camera at second store,
Equation describing the payment plan,
y = 15x + 79
Here, x = number of months
y = Total amount to be paid
If x = 12 months
y = (15×12) + 79
y = 180 + 79
y = $259
The camera at the second store is cheaper when the camera is paid off in 12 months because the cost at the first store is $289 and the cost at the second store is $259.
What is the slope of a line perpendicular to the line whose equation is x - 3y = -18. Fully reduce your answer.
Given:
Equation of a line is
[tex]x-3y=-18[/tex]
To find:
The slope of the line perpendicular to the given line.
Solution:
The slope of the equation [tex]ax+by=c[/tex] is
[tex]Slope=-\dfrac{a}{b}[/tex]
We have,
[tex]x-3y=-18[/tex]
Here, a=1, b=-3. So, slope of this line is
[tex]m_1=-\dfrac{1}{-3}[/tex]
[tex]m_1=\dfrac{1}{3}[/tex]
Product of slopes of two perpendicular lines is -1.
Let slope of perpendicular line is [tex]m_2[/tex].
[tex]m_1\cdot m_2=-1[/tex]
[tex]\dfrac{1}{3}\cdot m_2=-1[/tex]
[tex]m_2=-3[/tex]
Therefore, the slope of the perpendicular line is -3.

Answer:
Hope this helps~
Step-by-step explanation:
Look at the graph they gave you. ... At first it looks like an ugly mess.
But look closer. There are only two lines there that go through the origin,
so one of those is the answer to the question.
Now let's talk about the slope of a line.
-- If the slope of a line is positive, that means it rises as it goes.
If you walk the graph from left to right, you're climbing.
-- If the slope of a line is negative, that means it falls as it goes.
If you walk the graph from left to right, you're going down-hill.
The equation they gave you is [ y = 1/2 x ].
The slope is 1/2 . That's positive.
The line on the graph slopes up. To walk it, you have to climb.
In the picture, that can only be line 'c' .
Answer:
The equation they gave you is [ y = 1/2 x ].
The slope is 1/2. That's positive.
The line on the graph slopes up. To walk it, you have to climb.
Can someone help me plz and thank u
Answer:
<A = 44
Step-by-step explanation:
A triangle is 180 degrees
(x+59) + (x+51) + 84 = 180 >> add everything on the left side
2x + 194 = 180 >> subtract both sides by 194
2x = -14 >> divide both sides by 2 to get x alone
x = -7
since you are finding A<, substitute
<A = x + 51
<A = (-7) + 51
<A = 44

Answer:
1/3, 33.33%
Step-by-step explanation:
The full square is 6x6 which means there are 36 tiles in total. The shaded area is 3x4 which is 12. 12/36 is 1/3 simplified or 33.33%.
Answer:
1/3 and 33.33℅
Step-by-step explanation:
total number of rectangles is 36 and the shaded are 12
so 12/36 =1/3
1/3= 0.3333
to change to percent we multiply by 100
0.3333×100℅ = 33.33℅

Answer:
60°
Step-by-step explanation:
Since, all sides of the given triangle are marked with identical signs.
So, measures of all sides are equal.
Therefore, it is an equilateral triangle.
Measure of each angle of an equilateral triangle is 60°.
So, x = 60° ( Alternate angles)

Answer:
Option (3)
Step-by-step explanation:
If the sides of a triangle are unequal then the measure of sides opposite to these angle will be in the order from least to greatest.
In ΔABC,
m∠CAB = 180°- (m∠B + m∠C)
= 180° - (25° + 27°)
= 180° - 52°
= 128°
Since, ∠CAB > ∠ABC ∠ACB
Therefore, a > b > c ---------(1)
Now from ΔADB,
m∠BAD + m∠ADB + m∠DBA = 180°
32° + m∠ADB + m∠35° = 180°
m∠ADB = 180° - 67°
= 113°
Since, m∠ADB > m∠DBA > m∠BAD
Therefore, c > d > e -------(2)
Combining both the inequalities,
a > b > c > d > e

[tex]z = 40digree[/tex]
[tex]find y[/tex]
Answer:
x = 110
y = 110
Step-by-step explanation:
Here, we are going to apply an important triangle property
The sum of opposite interior angles equal the exterior angle of the third side
Thus, we have that;
y = 70 + 40 = 110
As we can see, the third angle in the triangle will be;
180-70-40 = 110
This is because sum of angles = 180
Thus, applying the exterior angle relationship,
x = 70 + 40 = 110
