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

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°.

Ricardo buys at least 8.5 but no more than 11
gallons of gas each week. The price of gas has
ranged from $2.40 to $2.65 per gallon each
week.
Answer:
Here we have two inequalities.
P is price of the gallon,we have that:
$2.40 ≤ P ≤ $2.65
C is the amount of gallons that Ricardo buys each week.
8,5 ≤ C ≤ 11
Now, with this you can find the maximum and minimum amount that he can spend on a week.
The minimum is when he buys only 8.5 gallons and the price per gallon is $2.40
Cost = 8.5*$2.40 = $20.4
The maximum cost is when he buys 11 gallons, and the price of the gallon is $2.65
Cost = 11*$2.65 = $29.15
So the amount that he spends per week in gas, S, is:
$20.4 ≤ S ≤ $29.15
27^x=1/9 find the value of x with steps
Answer:
x = -2/3
Step-by-step explanation:
27^x=1/9
writing 27 as 3^3 and 1/9 as 3 ^-2
3^3^x = 3^-2
We know that a^b^c =a^(b*c)
3^(3x) = 3^-2
Since the bases are the same the exponents need to be the same
3x = -2
x = -2/3

Step-by-step explanation:
An American motor company is releasing a new car model. There will be 2 body styles (2 or 4 door) from which to choose. They also offer 3 interior packages (deluxe, luxury, or special edition) and an option of 2 drive trains (front-wheel or four-wheel drive). If a local dealer wanted one of each possible model on her sales lot, how many cars would she need to order?
Answer:
She needs to order 12 cars
Step-by-step explanation:
To find the total number of models, we just need to multiply the number of options for each choice:
body style: 2 options
interior package: 3 options
drive train: 2 options
So the number of different models is:
2 * 3 * 2 = 12 different models
So in order to have all the possible models, she needs to order 12 cars.
usain bolt ran the 2012 olympic 100-meter race in 9.63 seconds. if he runs at this rate on a road wait a speed limit of 25 miles per hour, how will his speed compare to the speed limit? justify your answer.(25 mi/hr=40,234 meter/hr)
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.

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

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.

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

the perimeter of a stop sign is 99.2 inches. Each side of the stop sign is equal.
Write and solve an equation to find the measurement of one side of the stop sign n.
Answer: The equation can be written as 8n = 99.2.
Step-by-step explanation:
In my answer, I used the variable n to distinguish itself as one side of the stop sign. 99.2 is the final perimeter in inches.
A stop sign is an octagonal shape (otherwise, it is made up of 8 equal sides). Therefore, with this information, you can interpret that the length of one side would be equal to the length of all of the other sides.
Hence, the answer can be represented as 8n = 99.2.
Which of the following is not a true statement?
a) 4 * -3 = -8 - 4
b) 1/4 * -8 = 7 + -9
c) 3 + -7 =2 * -4
d) 8 / -2 = -10 + 6
Solve each equation to see if the left side equals the right side.
The answer would be C because when solved it becomes -4 = -8 which is false.
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.
