Answer:
a. 43
Step-by-step explanation:
This question is asking how much candy he had initially.
This means that t = 0 days
Thus anything to the power of 0 is just 1.
Hence: 43 x 1 = 43 candies
Plz help I literally suck at math... btw this is 6th grade math (there is an image)
Answer:
y=7x
Step-by-step explanation:
one way to think of it is by taking a y value from the table like (for example) 42 so you would do something like 42 divided by x = 6, or u could just do 42 divided by 6 which gives u 7. u can check ur answer by plugging in an x value to the equation. so for example we can plug in 8 to y=7x which is basically 7x8 and 7x8 is 56 which is true to the table.

Answer:
[tex]x=\frac{21}{4}[/tex]
[tex]y=\frac{21}{2}[/tex]
Step-by-step explanation:
equation (1): [tex]\frac{1}{2} (2x+y)=\frac{21}{2}[/tex]
equation (2): y=2x
solve the system by substitution
step1: sub (2x) for y in equation 1:
[tex]\frac{1}{2} (2x+y)=\frac{21}{2}[/tex]
[tex]\frac{1}{2} (2x+2x)=\frac{21}{2}[/tex]
step2: simplify the expression:
[tex]\frac{1}{2} (4x)=\frac{21}{2}[/tex]
[tex]2x=\frac{21}{2}[/tex]
(divide by 2 for both sides)
[tex]x=\frac{21}{4}[/tex]
To find the value for y sub 21/4 for x in equation 2:
y=2x
y=2×(21/4)
[tex]y=\frac{21}{2}[/tex]

A shirt is on sale for $15.75. This is 15% off the original price. What was the original price of the shirt?
$18.11
$13.39
$17.25
$18.53
Divide sale price by (1 - percent of discount):
15.75 / (1- 0.15) =
15.75 / 0.85 = 18.53
Answer = $18.53
Answer:
18.53
Step-by-step explanation:
18.53*0.15≈2.7795
Rounded = 2.78
18.53-2.78=15.75

Answer:
WX = [tex]\sqrt{74} \approx 8.6023253\\\\[/tex]XY = [tex]2\sqrt{37} \approx 12.1655251\\\\[/tex]WY = [tex]\sqrt{74} \approx 8.6023253\\\\[/tex]Classify: Isosceles============================================================
Explanation:
Apply the distance formula to find the length of segment WX
W = (x1,y1) = (-10,4)
X = (x2,y2) = (-3, -1)
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-10-(-3))^2 + (4-(-1))^2}\\\\d = \sqrt{(-10+3)^2 + (4+1)^2}\\\\d = \sqrt{(-7)^2 + (5)^2}\\\\d = \sqrt{49 + 25}\\\\d = \sqrt{74}\\\\d \approx 8.6023253\\\\[/tex]
Segment WX is exactly [tex]\sqrt{74}[/tex] units long which approximates to roughly 8.6023253
-------------------
Now let's find the length of segment XY
X = (x1,y1) = (-3, -1)
Y = (x2,y2) = (-5, 11)
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-3-(-5))^2 + (-1-11)^2}\\\\d = \sqrt{(-3+5)^2 + (-1-11)^2}\\\\d = \sqrt{(2)^2 + (-12)^2}\\\\d = \sqrt{4 + 144}\\\\d = \sqrt{148}\\\\d = \sqrt{4*37}\\\\d = \sqrt{4}*\sqrt{37}\\\\d = 2\sqrt{37}\\\\d \approx 12.1655251\\\\[/tex]
Segment XY is exactly [tex]2\sqrt{37}[/tex] units long which approximates to 12.1655251
-------------------
Lastly, let's find the length of segment WY
W = (x1,y1) = (-10,4)
Y = (x2,y2) = (-5, 11)
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-10-(-5))^2 + (4-11)^2}\\\\d = \sqrt{(-10+5)^2 + (4-11)^2}\\\\d = \sqrt{(-5)^2 + (-7)^2}\\\\d = \sqrt{25 + 49}\\\\d = \sqrt{74}\\\\d \approx 8.6023253\\\\[/tex]
We see that segment WY is the same length as WX.
Because we have exactly two sides of the same length, this means triangle WXY is isosceles.

Answer: b = 7.4 yards
Step-by-step explanation:
In a right angle triangle, the length of each base squared added together is equal to the hypotenuse squared (Pythagorean theorem written as a^2 + b^2 = c^2)
The bases are b and 3 and the hypotenuse is 8
b^2 + 3^2 = 8^2
b^2 + 9 = 64
b^2 = 55
the square root of 55 is approximately 7.4
Marisa’s mother is driving her to a doctor’s appointment in a town 75 mi. away. If they travel at a constant rate of speed of 50 mph, how long will it take to get to the doctor’s office? A. 1 hr. B. 1.5 hr. C. 2.5 hr. D. 3 hr.
Answer:
B) 1.5 hr
Step-by-step explanation:
75 miles/50 mph = 1.5 hrs
Answer:
B.1.5
Step-by-step explanation: We can already add 1 hour to the answer since 75 minus 50 would be 25. Next, we know that 25 is one half of 50 so that would result in us adding half an hour or 0.5. Now we can add. 1 plus 0.5 results in 1.5

Answer:
2/7
Step-by-step explanation:
This is easy! No need to over think it btw!
1) whenever you divide by a whole number such as in this case;4. You need to put a 1 under 4... like this: 4/1 (so it can become a fraction!)
2) Use KEEP, CHANGE, FLIP when you are dividing fractions!
8/7 --> you keep that number
÷ ---> × = you change the division sign into multplication sign
4 ---> 1/4 = you put 1 over 4 and flip it which you get from 4/1 --> 1/4
3) Your would look like this....
8/7 * 1/4 = ?
4) Muliply horizontally; 8 * 1 = 8 , 7 * 4 = 28
5) You get 8/28 Don't forget to simplify!!!
6) 8/4 / 32/4 = 2/7
ALSO, here's an example of KEEP, CHANGE, FLIP:

Aysha’s new bike has 26 inch diameter wheels. What is the circumference of her new wheel? Give your answer correct to 1 decimal place.
Answer:
81.6 inches is the circumference
Step-by-step explanation:
Circumference is π times diameter.
We can use a common value of π, 3.14
3.14 × 26 = 81.64
Round to 81.6 inches
Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2, and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.
1:Change the equation to slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all your work.
2:Describe how you would graph this line using the slope-intercept method. Be sure to write using complete sentences.
3:Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.
4:Graph the function. On the graph, make sure to label the intercepts. You may graph your equation by hand on a piece of paper and scan your work or you may use graphing technology.
5:Suppose Sal's total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different.
Answer:
Answer:
1.) the y intercept is 490 and the slope is -2/3x
2.) First, I would find the point (0,490) and plot a point there. Then I would use our slope -2/3 to figure out what direction and what angle the line goes by counting 2 down and 3 to the right
3.) f(x)= -2/3x+490
The graph represents how many wraps could've been sold for each number of sandwich sales to keep the same profit of $1,470.
4.) graph down below
5.) the profits are the same (slope) but the y intercept is higher then the original graph.
6.) y=-2/3x+300
Step-by-step explanation:
some of these are part of the problem as well.
1.) 2x+3y=1,470
3y=-2x+1,470
-2x+1,470/3
-2/3x + 490
y=-2/3x + 490
the y intercept is 490 and the slope is -2/3x
2.) First, I would find the point (0,490) and plot a point there. Then I would use our slope -2/3 to figure out what direction and what angle the line goes by counting 2 down and 3 to the right
3.) f(x)= -2/3x+490
The graph represents how many wraps could've been sold for each number of sandwich sales to keep the same profit of $1,470.
5.) 2x+3y=1,593
3y=-2x+1,593
y=-2/3x+531
the profits are the same (slope) but the y intercept is higher then the original graph.
6.) (150, 200) (300, 100)
y intercept= 300
m= 100-200/300-150 = -100/150 = -2/3
y=-2/3x+300
this was a question from a while ago but I thought I would answer it anyways, hope its right and hope it helps you! <3
