Quad. ABCD is a trapezoid.
XY is the median
XY = 12; AB=16
Find DC
Answers
Answer:
DC = 8
Step-by-step explanation:
The median is half the sum of the parallel bases, that is
[tex]\frac{AB+DC}{2}[/tex] = XY , substitute values
[tex]\frac{16+DC}{2}[/tex] = 12 ( multiply both sides by 2 to clear the fraction )
16 + DC = 24 ( subtract 16 from both sides )
DC = 8
Answer:
DC = 8
Step-by-step explanation:
The median XY of the trapezoid ABCD is half or the sum of AB and DC.
XY = 1/2 ( AB + DC)
We need to find out DC so we can rewrite this equation isolating DC
XY = (1/2)(AB+DC), multiply both sides by 2
2XY = AB + DC, subtract from both sides AB
2XY - AB = DC, now substitute the given AB = 16 and XY = 12
2* 12 - 16 = DC , using the order of operations rules we multiply first
24 -16 = DC, subtract
8 = DC

Under her cell phone plan, Rajani pays a flat cost of $65 per month and $5 per gigabyte. She wants to keep her bill under $85 per month. Write and solve an inequality which can be used to determine gg, the number of gigabytes Rajani can use while staying within her budget. need help with this
Answers
Answer: $85 [tex]\leq[/tex] $65 + ($5)*gg
Step-by-step explanation:
$85 [tex]\leq[/tex] $65 + ($5)*gg
The values are in $/month, but we'll assume 1 month is all we need to answer the question of what it would take to remain below $85/month. The fixed ciost, $65/month, is added to the gigabyte (gg) usage of $5/gg. (I'd prefer gb for gigabyte, but I'll stick with gg).
Together, they should be [tex]\leq[/tex] $85/month, thus we get:
$85 [tex]\leq[/tex] $65 + ($5)*gg

What is the difference of outputs for any two inputs that are one value apart?
A. -5
B. 1
C. 21.2
D. 27.2
Answers
Answer:
C
Step-by-step explanation:
The question wants you to calculate f(n)-f(n-1) using the data in the table. This could be done on any of the pairs, but I chose f(0)-f(-1) = 6 - (-15.2) = 21.2, giving us C as the final answer.
The local pool near Paxton's house charges a one-time registration fee of $18.25 and $17.50 per month. Last year, Paxton paid $105.75. How many months was Paxton a member of the pool?
Answers
Solving a linear equation we can see that Paxton was a member for 5 months.
How many months was Paxton a member of the pool?We know that the local pool near Paxton's house charges a one-time registration fee of $18.25 and $17.50 per month, then the cost for x months is modeled by the linear function.
f(x)= 18.25 + x*17.50
We know that Paxton paid $105.75, then we need to solve the equation:
105.75 = 18.25 + x*17.50
Solving that for x we will get:
105.75 - 18.25 = x*17.50
87.50/17.50 = x
5 = x
Paxton was a memeber for 5 months.

Write an explicit formula for the recursive formula
A(n) = A(n - 1) + 3; A(1) = 6
Answers
Answer:
[tex]a_{n}[/tex] = 3n + 3
Step-by-step explanation:
The sequence is arithmetic with explicit formula
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
From the recursive formula
a₁ = 6 and d = 3 [ the constant being added to A(n - 1) ] , then
[tex]a_{n}[/tex] = 6 + 3(n - 1) = 6 + 3n - 3 = 3n + 3

Teresa received a $90 gift card for a coffee store. She used it buying some coffee that cost $8.59 per pound. After buying the coffee, she had $38.46 left on her card. How many pounds of coffee did she buy?
Answers
Answer:
6 pounds of coffee
Step-by-step explanation:
Given Teresa's $90 gift card for a coffee store, and a balance of $38.46 on her card:
Subtract the remaining balance of $38.46 from the $90 original balance on Teresa's card, to determine how much she spent on coffee.
$90.00 - $38.46 = $51.54
Next, divide the amount that she spent at the coffee store by the $8.59 cost per pound to find out how many pounds of coffee she purchased from the store:
$51.54 ÷ $8.59 per pound = 6 pounds
Therefore, she bought 6 pounds of coffee worth $51.54 from the store.

Enter the correct answer in the box.
Answers
Answer:
100 meters is 8.6 meters longer than 100 yards.
Step-by-step explanation:
Conversion of yards to meters.
Each yard has 0.914 meters.
So 100 yards is 100*0.9144 = 91.4 meters.
How many meters longer to the nearest tenth is 100 meters than 100 yards?
100 yards = 91.4 meters
100 - 91.4 = 8.6
So 100 meters is 8.6 meters longer than 100 yards.
