Answer:
13.6
Step-by-step explanation:
The measure of the segment AQ is related to the measure of the segment A'Q by the dilation factor as follows:
dilation factor = A'Q/AQ
AQ = A'Q/dilation factor
Replacing with data:
AQ = 2.4/0.15 = 16
Then, the distance between points A and A' is
x = 16 - 2.4 = 13.6

Solve for t.
–17t = –9(3t + 17) − 7
t =
Answer:
t = -16
Step-by-step explanation:
→Distribute the -9 to (3t + 17):
-17t = -9(3t + 17) - 7
-17t = -27t - 153 - 7
→Add like terms:
-17t = -27t - 160
→Add 27t to both sides:
10t = -160
→Divide both sides by 10:
t = -16
Answer:
[tex] \boxed{t = - 16} [/tex]
Step-by-step explanation:
[tex] = > - 17t = - 9(3t + 17) - 7 \\ \\ = > - 17t = - (9 \times 3t) - (9 \times 17) - 7 \\ \\ = > - 17t = - 27t - 153 - 7 \\ \\ = > - 17t = - 27t - 160 \\ \\ = > - 17t + 27t = - 160 \\ \\ = > 10t = - 160 \\ \\ = > t = - \frac{160}{10} \\ \\ = > t = - 16[/tex]

Sidney is eating lunch at a salad bar where you
create your own salad. An 8-ounce salad costs
$2.49. Each additional ounce of salad costs
$0.25. How much does Sidney’s salad cost if it
weighs 1 pound, 8 ounces?
Answer:
$7.47
Step-by-step explanation:
Since a 8-ounce salad cost 2.49
You do 2.49+1 pound times 0.25
1 pound equals to 16 ounces
2.49 + 2.49 + 2.49
Correct. If I am wrong
Answer:
Step-by-step explanation:
the base is 2.49 for eight ozs so you already take off the ozs from 1 pound
since there are 16 ounces in one pound you multiply 16 by .25 and get 4 so you add 2.49 and 4 to get 6.49$ is the answer assuming there is no tax on the food

Use the discriminant to determine the number of real solutions of the equation.
x^2 = -6x - 10
Answer:
No real solutions.
Step-by-step explanation:
x² + 6x + 10 = 0
a = 1
b = 6
c = 10
D = b² - 4ac = 6² - 4*1*10 = 36 - 40 = - 4
- 4 < 0,
so this equation has no real solutions.
Circle O is shown. Line segments C O And A O are radii. Lines are drawn from points C and A to point B to form chords B C and B A. Angle C B A is 80 degrees. What is the measure of angle COA? 140° 150° 160° 170°
Answer:
Its 160 on ED
Step-by-step explanation:
Based on the angle-arc relationship, the measure of angle COA is: C. 160°.
What is the Angle-Arc Relationship?The angle-arc relationship relates the measure of an inscribed angle to its central angle, such that the central angle is twice the measure of the intercepted arc.
Given:
m∠CBA = 80° (intercepted arc)m∠COA = ?° (central angle)Therefore:
m∠COA = 2(m∠CBA)
Substitute
m∠COA = 2(80°)
m∠COA = 160°
Therefore, based on the angle-arc relationship, the measure of angle COA is: C. 160°.

Answer:
Usain Bolt runs about 37,383 meters an hour so he will not exceed the speed limit but will run at about 23 miles per hour.
Step-by-step explanation:
Usain Bolt runs about 37,383 meters an hour so he will not exceed the speed limit but will run at about 23 miles per hour. We get this from 3600 seconds in an hour, 3600÷9.63×100≈37383 meters an hour. 1609.344 meters in a mile. 37383÷1609.344≈23 mph
Answer:Sample Response: The speed limit is about 11.2 meters per second. Usain is running 10.38 meters per second. So he is running slower than the speed limit.

Help to answer 2 & 3 Pablo and Jasmine had just started studying systems of linear equations in algebra. They looked at Pedro's drawing and said, "We could write that as a system of equations." Let t be the price of each taco and d be the price of each drink. - Write an equation that represents the cost of Pablo's order. (6T + 2D = 9) - Write an equation that represents the cost of Jasmine's order. (4T + 2D = 7) 2. What operations with the equations from part (1) match your way of using Pedro's sketch to find the prices t and d? 3. Why do the operations make sense?
Answer:
Step-by-step explanation:
The equation for Pablo's order is given as 6T+2D=9 or 6T+2D-9=0
While the equation for Jasmine's order is given as 4T+2D=7 or 4T+2D-7=0
Subtracting Jasmine's equation from Pablo's
6T+2D-9-(4T+2D-7)=0
This gives us
6T+2D-9-4T-2D+7=0
The reduces to
2T-2=0
Dividing all through by 2 gives
T-1=0
Therefore
T=1
Substituting the value for T into any of the equations of either Pablo and Jasmine
Using Pablo's
6T+2D=9
6(1)+2D=9
2D=9-6
2D=3

On a coordinate plane, 5 parallelograms are shown. Parallelogram L M N P has points (3, 1), (4, 1), (4, 3), and (5, 3). Figure D is reflected across the x-axis. Figure B is reflected across the y-axis. Figure C is rotated in the first quadrant. Figure A is rotated in the third quadrant. Which figure represents the image of parallelogram LMNP after a reflection across the line y = x? figure A figure B figure C figure D
Answer:
Figure C
Step-by-step explanation:
Reflection across the line y = x transforms point (x, y) into (y, x)
(3, 1) -> (1, 3)
(4, 1) -> (1, 4)
(4, 3) -> (3, 4)
(5, 3) -> (3, 5)
After rotation, all points remain in the first quadrant. Figure C is rotated in the first quadrant, then it is the correct option.
Because Figure C is rotated in the first quadrant,its represents the image of parallelogram LMNP after a reflection across the line y = x
What is a Parallelogram?A Parallelogram is simply a four-sided quadrilateral with opposite sides parallel to each other.
