Step-by-step explanation:
Answer:
t = 1
Step-by-step explanation:
When you cross multiply the equation becomes:
10(t+8)=10(9)
Now, solve for t.
10(t-8) = 10(9)
10t+80= 90

Write an equation of the line in slope intercept form
Answers
Answer: y = x + 2 OR f(x) = x + 2
Step-by-step explanation:
Calculating slope:
Remember rise over run; when going from one point to another point, in this case from (-3, -1) to (0,2), locate the distance moved in the x and y directions. This scenario moves 3 up and 3 right, meaning a positive slope of one. However, if the line was directed left, your slope would be negative.
Finding y-intercept:
Where does the line intersect the y-axis and have a x-value of 0? This is your y-intercept --> (0,2).
Write Equation:
y = mx +b
y = 1x + 2
y = x + 2 (your final answer)
An airplane descends 1.5 miles to an elevation of 6.05.Find the elevation of the plane befor its descent the intial elevation of the plane was blank miles
Answers
Answer:
7.55 miles
Step-by-step explanation:
Given that :
Distance of descent = 1.5 miles
New elevation point after descent = 6.05 miles
The initial elevation of the plane before descent will be :
New elevation point after descent + Distance of descent
(6.05 miles + 1.5 miles)
= 7.55 miles
A man sold a fan for Rs. 400. Find the cost price if he incurred a loss of 15%.
Answers
Answer:
Cost price of the fan is [tex]\text {Rs. 470.59}[/tex].
Step-by-step explanation:
Given: A man sold a fan for [tex]\text{Rs.}\:400[/tex]. He incurred a loss of [tex]15\%[/tex].
To find: The cost price of the fan
Solution:
We have,
Selling price, S.P., of the fan [tex]= \text{Rs.} 400[/tex]
Loss [tex]=15\%[/tex]
We know that [tex]\text {Loss\%}=\frac{\text{C.P.-S.P.}}{\text{C.P.}}\times100\%[/tex]
Now let the C.P. of the fan be [tex]\text{Rs.} \:x[/tex]
So, [tex]15=(\frac{x-400}{x})\times 100[/tex]
[tex]\implies 15x=100x-40000[/tex]
[tex]\implies 100x-15x=40000[/tex]
[tex]\implies 85x=40000[/tex]
[tex]\implies x=\frac{40000}{85}[/tex]
[tex]\implies x= 470.59[/tex]
Hence, the cost price of the fan is [tex]\text {Rs. 470.59}[/tex].
Little billy wants to buy a pineapple upside down came. The cakes are 2 days old so they are 70% off! The original price is $20. What is the sale price
Answers
Answer:
$6
Step-by-step explanation:
Original price of the pineapple = $20
Percentage off = 70%
Amount discounted = 70% of $20
Amount discounted = 0.7 * 20
Amount discounted = $14
Sale price = Original price - Discount
Sale price = $20 - $14
Sale price = $6
Hence the sale price was $6

Answer:
(b) 13.5
Step-by-step explanation:
The upper vertex would be ...
3/2(3, 3) = (4.5, 4.5)
and the right vertex would be ...
3/2(4, 0) = (6, 0).
The base of the larger triangle would be 6, and its height would be 4.5. Then the area is ...
A = (1/2)bh
A = (1/2)(6)(4.5) = 13.5 . . . area of dilated triangle

Step-by-step explanation:
Given : Rachel has [tex]\dfrac23[/tex] pound of snack mix..
If she ate [tex]\dfrac5{12}[/tex] of the snack mix.
Then, Quantity of snack mix eaten by Rachel = [tex]\dfrac5{12}\times\dfrac23[/tex]

The discriminant D = b² - 4ac tells the types of roots the equation has.
If D < 0 , then quadratic equation has no real roots, has two imaginary roots.
If D = 0 , then quadratic equation has one real root.

Determine whether the representation is proportional. y = -9x
Answers
Answer:
Yes, they are
Step-by-step explanation:
y = -9x
Here y∝ x
Where -9 is constant of proportionality
If "y" increases by factor of 2, then "x" will also increases by factor of 2. Hence, y and x are " directly proportional" to each other.
Clara found the product of 3 – 6y2 and y2 + 2. Her work is shown below.
(3 – 6y2)(y2 + 2) = 3(y2) + (–6y2)(2)
= 3y2 – 12y2
= –9y2
Is the student’s work correct?
Answers
Answer: No the students work is not correct. Because you are using distribution. Which means that 3 has to multiply the y2 and 2 not just the y2! And after you distribute it you need to simplify!
Step-by-step explanation:
Answer:
(3 – 6y²)(y² + 2) = - 6y⁴ - 9y² + 6
Step-by-step explanation:
Given the expression
3-6y² and y²+2
We have to find the product of 3-6y² and y²+2
Clara's Solution:
(3 – 6y²)(y² + 2) = 3(y²) + (–6y²)(2)
= 3y² – 12y²
= -9y²
NO!
The student's work is INCORRECT!
Clara did not imply the correct distribution of multiplying the terms in the first step.
Here is the correct solution:
(3 – 6y²)(y² + 2) = 3(y²) + (–6y²)(2) + (3)(2) + (–6y²)(y²)
= 3y² – 12y² + 6 - 6y⁴
= - 6y⁴ - 9y² + 6
Therefore,
(3 – 6y²)(y² + 2) = - 6y⁴ - 9y² + 6

Find the missing terms 14.5_,_,18.4
Answers
The 4th term is a + 3d = 18.4
We know what a is so we can substitute it into the above equation...
14.5 + 3d = 18.4
3d = 3.9
d = 1.3
So the common difference is 1.3... now you just have to add that to the first term so...
14.5 + 1.3 = 15.8 (2nd term)
15.8 + 1.3 = 17.1 (3rd term)
