Answer:
Angle: A figure formed by two rays or line ... Time Period 3: Geometric Relationships & Properties, 15 blocks ... dilation of the polygon with that point as the center. Identify the scale factor that you used. G-SRT 2. Given two figures, use the ... the circle centered at the origin and ... Write an equation for a circle with a radius of 2.
Step-by-step explanation:
The equation of the line of dilation centered at the origin with a scale factor of k=3 is,
⇒ y' = (6/5)x + 3.
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Now, To find the equation of the line of dilation centered at the origin with a scale factor of k=3,
we need to apply the dilation transformation to the given equation.
First, we need to rewrite the equation in slope-intercept form:
-2x + 5y = 15
5y = 2x +15
y = (2/5)x + 3
Now, we can apply the dilation transformation by multiplying the slope by the scale factor k = 3;
y' = k y
y' = 3 (2/5)x + 3
y' = (6/5)x + 3
Therefore, the equation of the line of dilation centered at the origin with a scale factor of k=3 is,
y' = (6/5)x + 3.

Which expression has the sum of 11/12
A. 1/12+5/12+5/12
B. 5/4+3/4+3/4
C. 5/6+6/6
D. 10/12+2/12
I’m 13 and don’t understand this at all.
Answer:
A. 1/12+5/12+5/12
Step-by-step explanation:
From the given options; let us calculate the fractions and see which one tallies with 11/12
a) [tex]\dfrac{1}{12}+ \dfrac{5}{12} + \dfrac{5}{12}[/tex]
The lowest common multiple (L.C.M) here is 12 because 12 goes in all the denominators.
So;
[tex]= \dfrac{1+5+5}{12}[/tex]
[tex]= \dfrac{11}{12}[/tex]
b)
[tex]\dfrac{5}{4}+\dfrac{3}{4}+\dfrac{3}{4}[/tex]
Here, the lowest number that can be divisible by the denominators is 4
[tex]=\dfrac{5+3+3}{4}[/tex]
[tex]=\dfrac{11}{4}[/tex]
c)
[tex]\dfrac{5}{6}+\dfrac{6}{6}[/tex]
[tex]=\dfrac{5+6}{6}[/tex]
[tex]=\dfrac{11}{6}[/tex]
d)
[tex]\dfrac{10}{12}+\dfrac{2}{12}[/tex]
[tex]=\dfrac{10+2}{12}[/tex]
[tex]= \dfrac{12}{12}[/tex]
= 1
Thus, from the given options, the expression that has the sum of 11/12 is option A.

Azli has RM (h²-64). He wants to buy RM (h-8) packs of flour. How much is a pack of flour?
Answer:
Cost of one pack = h+8
Step-by-step explanation:
Given that:
Amount Azil have = RM (h²-64)
Packs of flour Azil wants to buy = h-8
To find the price of a pack of flour, we will divide the total amount by packs of flour.
Unit rate = [tex]\frac{h^2-64}{h-8}[/tex]
Unit rate = [tex]\frac{h^2-8h+8h-64}{h-8} = \frac{h(h-8)+8(h-8)}{h-8}[/tex]
Unit rate = [tex]\frac{(h-8)(h+8)}{(h-8)}[/tex]
Unit rate = h+8
Hence,
Cost of one pack = h+8

Answer:
The measure of angle A is:
m ∠ A = 53.13°
Step-by-step explanation:
Given
The length AC = 3 cm
The length BC = 4 cm
To determine
m ∠ A = ?
Using the trigonometric ratio
tan A = opposite / adjacent
From the right-angled triangle, as shown, it is clear that:
The opposite of m ∠ A is the side BC = 4 cmThe adjacent of m ∠ A is the side AC = 3 cmThus, substitute opposite = 4 and adjacent = 3
tan A = 4 / 3
A = arctan (4/3)
A = 53.13°
Therefore, the measure of angle A is:
m ∠ A = 53.13°

adita spends more than 24 dollars at the gift shop she buys a mug for 9 dollars and 3 books that cost the same amount which inequality shows the cost in dollars d of each book answers
Answer: x > 5.
Step-by-step explanation:
The information given in the question can be expressed in an equation as:
Let the cost of each book be x
Cost of mug + Cost of books > 24
9 + (3 × x) > 24
9 + 3x > 24
3x > 24 - 9
3x > 15
x > 5.
Therefore, each book cost more than $5.

x=9
Answer:
x = 0.327
Step-by-step explanation:
[tex]\frac{21}{4}[/tex] = [tex]\frac{12}{7}[/tex] ÷ x
[tex]\frac{21}{4}[/tex] = [tex]\frac{12}{7}[/tex] × [tex]\frac{1}{x}[/tex]
[tex]\frac{21}{4}[/tex] = [tex]\frac{12}{7x}[/tex]
[tex]\frac{21}{4}[/tex] x 7x = 12
[tex]\frac{147x}{4}[/tex] = 12
147x = 12 x 4
x = 48 ÷ 147
x = 0.327

Taliyah has 174 coins in her collection of dimes and nickels. The total value of the collection is $15.20. How many dimes does she have in her collection?
Answer:
130 dimes
Step-by-step explanation:
A nickel is worth 5 cents = 0.05n
A dime is worth 10 cents = 0.10d
Taliyah has 174 coins in her collection of dimes and nickels.
n + d = 174
n = 174 - d
The total value of the collection is $15.20.
0.05n + 0.10d = $15.20
We substitute 174 - d for n
Hence:
0.05(174 - d) + 0.10d = 15.20
8.7 - 0.05d + 0.10d = 15.20
- 0.05d + 0.10d = 15.20 - 8.7
0.05d = 6.5
d = 65/0.05
d = 130 dimes
The number of dimes she has in her collection is 130 dimes
Gwen's blog post about camping has 70 comments. 30% of the comments were questions for Gwen about camping gear. How many of the comments were questions about camping gear? Pick the model that represents the problem.
To figure out how many of the 70 comments were those about questions for Gwen about camping gear, you need to first find the decimal of 30%, which is 0.3. Then the equation should be:
70 x 0.3
Answer: 21
Answer:21 comments about camping gear
Step-by-step explanation: Because percentages are just fractions out of 100, we know that 30% is 30/100. If you multiply 30/100 by 70, you get 21.
