Answer:
18cm
if it takes 12cm to wrap 6 presents, it means it takes 2cm to wrap one present.

The probability of obtaining a head when a certain coin is flipped is about 0. 65. Which of the following is closest to the probability that heads would be obtained 15 or fewer times when this coin is flipped 25 times?.
The probability that heads would be obtained 15 or fewer times when this coin is flipped 25 times is 0.370
How to determine the probability?The given parameters are:
Sample size, n = 25Probability of success, p = 0.65Number of success, x ≤ 15The probability is represented using the following binomial formula
[tex]P(x) = ^nC_x * p^x * (1 - p)^{n - x}[/tex]
Using the above formula, we have:
[tex]P(x \le 15) = 0.370[/tex]
Hence, the probability is 0.370

Riley drank 8/10 quart of iced tea and her friend drank 0.3 quart. How much more of a quart of iced tea did Riley drink than her friend?
Answer:
1/2
Step-by-step explanation:
0.3 can be converted into 3/10. TO find out how much more of a quart of iced tea that Riley drank than her friend, we have to subtract the amount of iced tea that her friend drank from the amount that Riley drank.
8/10 - 3/10 = 5/10
Now, we have the opportunity to simplify the fraction. 5/10 is the same as 1/2. Therefore, Riley drank 5/10, or 1/2, more than her friend. I hope this helps! Have a lovely day!! :)

Answer:
Shown Below...
Step-by-step explanation:
6) 5.25% will be 5.25/100 = 0.0525
0.0525 x $333.75 = $17.5 (rounded)
$333.75 + $17.5= $351.25
7) 15% will be 15/100 = 0.15
0.15 x $16 = $2.4
$16 + $2.4 = $18.4
8) 20% will be 20/100 = 0.2
0.2 x $2800 = $560
Since it is off the original price, this will be subtraction.
$2800 - $560 = $2240 will be the sales price.
----------
8.25% will be 8.25/100 = 0.0825
0.0825 x $2240 = $184.8
$2240 + $184.8 = $2424.8 will be the total price including tax.

Suppose you know the following facts about angle ABC and angle DEF: (1) both triangles have sides of length a and b (2) For angle ABC, a^2 + b^2 = c^2 (3) For angle DEF, angle F is a right triangle. Use the list of expressions below to find the value of c in angle ABC and the length of the hypotenuse of angle DEF.
The value of c in angle ABC is _______ and the length of the hypotenuse of angle DEF is ________.
A. square root of a^2 + b^2
B. a^2 + b^2
C. b^2 - a^2
D. square root of a^2 - b^2
E. a^2 - b^2
F. square root of b^2 - a^2
(if u have trouble reading the text look at the attached photo for the question)
Answer:
A. square root of a^2 + b^2 for both answers
Step-by-step explanation:
The first problem, we are given
a^2 + b^2 = c^2
What we do is solve for c.
sqrt(a^2 + b^2) = c
c = sqrt(a^2 + b^2)
For problem 2,
WE can apply the Pythagorean theorem because we have a right triangle.
The equations is
a^2 + b^2 = c^2 like the first problem
Solving gets us
sqrt(a^2 + b^2) = c
c = sqrt(a^2 + b^2)
y + 6 = 5(x – 4)
Write a formula fpr f(x) in terms of x.
Answer:
f(x) = 5x - 26
Step-by-step explanation:
y + 6 = 5(x - 4) ← distribute parenthesis by 5
y + 6 = 5x - 20 ( subtract 6 from both sides )
y = 5x - 26
Now y = f(x) , then
f(x) = 5x - 26
Answer:
f(x) = 5x - 26
Step-by-step explanation:
y + 6 = 5(x – 4)
Distribute
y +6 = 5x - 20
Solve for y
y +6-6 = 5x-20+-6
y = 5x - 26
Replace y with f(x)
f(x) = 5x - 26

What is the surface area of the right cone below?
A. 3047 units-
B. 4967 units?
C. 1841 units-
D. 248 units
Answer:
184π units²
Step-by-step explanation:
see attached for reference
given sloped height = 15 units
base radius = 8 units
the height of the cone can be found by using the Pythagorean equation
(sloped height)² = height ² + (base radius)²
15² = h² + 8²
h² = 15²-8² = 161
h = √161
Base surface area = πr² = π 8² = 64π units²
Lateral Surface Area,
= πr √(r² + h²)
= π(8) √[ (8)² + (√161)² ]
= 8π√(64 + 161)
= 8π√225
= 8π (15)
= 120π
Surface area = base area + lateral surface area
= 64π + 120π
= 184π units²
Answer:
C. 184π units²Step-by-step explanation:
Surface Area of a cone : πrl + πr² = πr(l + r)
r = radiusl = slant heightSolving
SA = π x 8 (15 + 8)SA = π x 8 x 23SA = 184π units²HII can someone plss help me with this question. I got 192 but i dont know how to turn it into a base with an exponent. ----> b^e

Answer:
1) x=−y-2
2)x=−y+2
Step-by-step explanation:
Let's solve for x.
y=−x−2
Step 1: Flip the equation.
−x−2=y
Step 2: Add 2 to both sides.
−x−2+2=y+2
−x=y+2
Step 3: Divide both sides by -1.
x=−y−2
Let's solve for x.
3x+3y=6
Step 1: Add -3y to both sides.
3x+3y+−3y=6+−3y
3x=−3y+6
Step 2: Divide both sides by 3.
x=−y+2

The annual percentage rate of the loan is approximately 913%. option c is correct.
What is the annual percentage?The yearly interest earned by an amount charged to borrowers or paid to investors is referred to as the annual percentage rate.
APR is a percentage that indicates the real annual cost of money for a loan or investment over the period of the loan.
The amount borrowed = $75
no of days =8 days
Fees charged = $15
The annual percentage is found as;
[tex]\rm r = \frac{final \ value}{initial \ value } -1 \\\ \rm r = \frac{f 90}{75 } -1 \\\\ r=0.20 \\\\[/tex]
If the rate of interest is 20% then the annually the rate is obtained as;
[tex]\rm r_{annual}= \frac{0.20}{8 \ days} \times \frac{365}{1 \ year} \\\\ \rm r_{annual}=913 /year[/tex]
Hence the annual percentage rate of the loan is approximately 913%. option c is correct.
