Annie earns $320 for 8 hours of work. At that rate, how long would she have to
work to earn $1,120?
Answers
Answer:
28 hrs
Step-by-step explanation:
in 8 hrs she earns $320,
so in 1 hr she earns $320/8=$40
no. of hrs she takes to earn $1120 is,
=1120/40= 28 hrs
Annie would need to work 28 hours to earn $1,120 at the same rate.
To determine how long Annie would have to work to earn $1,120 at the same rate, we can set up a proportion based on the given information.
Let's define:
x = the number of hours Annie needs to work to earn $1,120.
According to the information given, Annie earns $320 for 8 hours of work. This can be expressed as the rate: $320/8 hours.
We can set up the proportion as follows:
320/8 = 1120/x
To solve this proportion, we can cross-multiply and then solve for x:
320x = 8 * 1120
320x = 8960
Dividing both sides of the equation by 320:
x = 8960/320
x = 28
Therefore, Annie would need to work 28 hours to earn $1,120 at the same rate.

A triangle has vertices of (−3, 3), (−3, 2), and (1, −2). What are the coordinates after dilating from the origin by a scale factor of 1 2 ?
Answers
Answer:
(-1.5, 1.5), '(-1.5, 1) and (0.5, -1)
Step-by-step explanation:
Given the coordinate (x, y) If dilated by a factor k, the resulting coordinate will be (kx, ky).
Similarly given the coordinates of a triangle (−3, 3), (−3, 2), and (1, −2)
when dilated by a factor of 1/2, the new coordinates will be at;
A (-3, 3) = A'(1/2*-3, 1/2 * 3) = A'(-1.5, 1.5)
B (-3, 2) = B'(1/2*-3, 1/2 * 2) = B'(-1.5, 1)
C (1, -2) = C'(1/2*1, 1/2 * -2) = C'(0.5, -1)

the cosine rule calculate tha angle of r 7.2 3,7 5.2
Answers
Given:
Consider the below figure attached with this question.
To find:
The measure of angle r by using the cosine rule.
Solution:
According to Law of Cosine,
[tex]a^2=b^2+c^2-2bc\cos A[/tex]
Using the Law of Cosine, we get
[tex](7.2)^2=(3.7)^2+(5.2)^2-2(3.7)(5.2)\cos r[/tex]
[tex]51.84=13.69+27.04-38.48\cos r[/tex]
[tex]51.84=40.73-38.48\cos r[/tex]
[tex]51.84-40.73=-38.48\cos r[/tex]
On further simplification, we get
[tex]11.11=-38.48\cos r[/tex]
[tex]\dfrac{11.11}{-38.48}=\cos r[/tex]
[tex]-0.2887=\cos r[/tex]
[tex]\cos^{-1}(-0.2887)=r[/tex]
[tex]106.780143=r[/tex]
[tex]r\approx 106.78[/tex]
Therefore, the measure of angle r is 106.78 degrees.
