Answer:
[tex]s = 8+b\\2s+3b=156[/tex]
Step-by-step explanation:
To find which systems of equation represents the situation, we can break down the key information and create two variables:
Variables:
Let [tex]s[/tex] = number of sundaes sold.
Let [tex]b[/tex] = number of banana splits sold.
Given information:
Sundae: [tex]\$2[/tex]
Banana Splits: [tex]\$3[/tex]
8 more sundaes sold than banana splits. This can be expressed by [tex]s=8+b[/tex].
Total sold was [tex]\$156[/tex]. This can be expressed as [tex]2s+3b=156[/tex].
∴ The systems of equation that expresses this situation are [tex]s=8+b[/tex] and [tex]2s+3b=156[/tex].
Hope this helps :)
The nth term of an AP is 12-4n. Find the first term and the common difference.
Answer:
first term is 8 and common difference d is -4
Step-by-step explanation:
nth term of an arithmetic sequence is: aₙ=12-4n
First term is putting n=1:
aₙ=12-4n
a₁=12-4(1)
a₁=12-4
a₁=8
So, first term a₁= 8
Now finding second term to find common difference
Second term is: n=2
aₙ=12-4n
a₂=12-4(2)
a₂=12-8
a₂=4
So, second term is: 4
The common difference is: a₂-a₁= 4-8 = -4
So, first term is 8 and common difference d is -4 if nth term is 12-4n
Divers erected a cage in a shape of an upright cylinder on rhe ocean floor for protection. The diameter of the base measures 32 feet. How much space on the ocean floor does the cage have
Answer:
The cage will cover an area of 805 ft^2 on the Ocean floor
Step-by-step explanation:
To calculate the amount of space the cage has on the Ocean floor, we calculate the area of the base of the cylinder
Mathematically, that will be pi * d^2/4
= 22/7 * (32 * 32)/4
= 22/7 * 256 = 804.5714285714286
The cage will cover an area of 805 ft^2 on the ocean floor

Answer:
we conclude that in the second step, 3 should have been subtracted from the right side as well on the left side.
Step-by-step explanation:
Given the expression
[tex]4 < -2x + 3 < 9[/tex]
SECOND STEP
subtract 3 from the right-hand side as well as on the left-hand side
[tex]4-3 <-2x+3-3<9-3[/tex]
SOLVING THE REMAINING COMPLETE COMPRESSION
[tex]1 < -2x < 6[/tex]
Divide all parts by -2
Please note that multiply or divide an inequality by a negative number flips the inequality sign.so the expression becomes
[tex]\frac{1}{-2}\:<\:\frac{-2x}{-2}\:<\:\frac{6}{-2}[/tex]
[tex]\frac{1}{-2}\:>x\:<\:-3[/tex]
Hence, from the explanation, we conclude that in the second step, 3 should have been subtracted from the right side as well on the left side.

Answer:
B. 14Step-by-step explanation:
The Greatest Common Factor (GCF) for 14 and 56, notation CGF(14,56), is 14.
Explanation:
The factors of 14 are 1,2,7,14;
The factors of 56 are 1,2,4,7,8,14,28,56.
So, as we can see, the Greatest Common Factor or Divisor is 14, because it is the greatest number that divides evenly into all of them.

This equation shows how the number of pictures Carrie has taken so far this year is related to the number of days she spends on vacation. p = d + 9. The variable d represents the number of days she spends on vacation, and the variable p represents the total number of pictures taken this year. How many days will Carrie have to spend on vacation before she will have taken 17 pictures? *
Answer: 8
Step-by-step explanation: Carrie already has taken 9 pictures. This means you have to subtract 9 from 17. That leaves 8 more photos to take.
Find the probability. A cooler contains fifteen bottles of sports drink: seven lemon-lime flavored and eight orange flavored. You randomly grab a bottle and give it to your friend. Then, you randomly grab a bottle for yourself. You and your friend both get lemon-lime. 3 13 ≈ 0.231 4 9 ≈ 0.444 1 5 = 0.2 4 15 ≈ 0.267
Answer:
[tex]\dfrac{4}{15} \approx \bold{0.267}[/tex]
Step-by-step explanation:
Given that:
Number of lemon - lime flavored bottles = 8
Number of orange flavored bottles = 7
Bottles are picked one by one.
First for the friend and then for the person himself.
To find:
The probability that both the bottles drawn are of lemon-lime flavor.
Solution:
Total number of bottles available in the cooler = 8 + 7 = 15
Formula for probability of an event E can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
[tex]P(First\ lemon-lime) = \dfrac{8}{15}[/tex]
Now, lemon - lime flavored bottles left = 7
Total number of bottles left = 14
[tex]P(Second\ lemon-lime)=\dfrac{7}{14}[/tex]
Required probability:
[tex]P(Both\ lemon - lime) = \dfrac{8}{15}\times \dfrac{7}{14}\\\Rightarrow P(Both\ lemon - lime) = \dfrac{4}{15} \approx \bold{0.267}[/tex]

A gardener is planting two types of trees: Type A is 10 feet tall and grows at a rate of 19 inches per year. Type B is 4 feet tall and grows at a rate of 25 inches per year. Algebraically determine exactly how many years it will take for these trees to be the same height.
Answer:
It'll take 12 years
Step-by-step explanation:
Given
Type A:
[tex]Initial\ Height = 10ft[/tex]
[tex]Growth = 19in[/tex]
Type B:
[tex]Initial\ Height = 4ft[/tex]
[tex]Growth = 25in[/tex]
Required
Determine the years they'll reach the same height
First, convert feet to inches in both measurements (this is done by multiplying measurement by 12):
Type A:
[tex]Initial\ Height = 10ft[/tex]
[tex]Initial\ Height = 10 * 12in[/tex]
[tex]Initial\ Height = 120in[/tex]
Type B:
[tex]Initial\ Height = 4ft[/tex]
[tex]Initial\ Height = 4 * 12in[/tex]
[tex]Initial\ Height = 48in[/tex]
The height at any year from both trees is calculated using
[tex]Height = Iniital\ Height + Growth * x[/tex]
Where x represents the year;
For Type A:
[tex]Height = 120+ 19 * x[/tex]
[tex]Height = 120+ 19x[/tex]
For Type B:
[tex]Height = 48+ 25 * x[/tex]
[tex]Height = 48+ 25x[/tex]
To get when their height will be equal, we simply equate both expressions:
[tex]48+ 25x = 120 + 19x[/tex]
Collect Like Terms
[tex]25x - 19x= 120 - 48[/tex]
[tex]6x= 72[/tex]
Solve for x
[tex]x = 72/6[/tex]
[tex]x = 12[/tex]
Hence, It'll take 12 years

Find the x- and y-intercepts of the equation 3x - 7y= 21.
A) x-intercept: (7,0), y-intercept: (0,3)
B) x-intercept: (7,0), y-intercept: (0,-3)
C) x-intercept: (0,7), y-intercept:(-3,0)
OD) x-intercept: (0,-7), y-intercept: (3,0)
x-intercept: (7,0), y-intercept: (0,-3). Therefore, the correct answer is option B.
The given equation of a line is 3x-7y=21.
The x-intercept is the value of the x-coordinate of a point where the value of y-coordinate is equal to zero.
When y=0, we get
3x-7(0)=21
3x=21
x=7
So, the x-intercept is (7, 0)
The y-intercept is the value of the y-coordinate of a point where the value of x-coordinate is equal to zero.
When x=0, we get
3(0)-7y=21
0-7y=21
y=-3
So, the y-intercept is (0, -3)
Therefore, the correct answer is option B.

Assuming only the lengths of the sides of a triangle are given, how can you determine if the triangle has a right angle?
By the Pythagorean Theorem, the lengths of the sides of a triangle satisfy [tex]a^2+b^2=c^2[/tex] if the triangle is a right triangle (in which case the angle between sides a and b is the right angle).
Use the change of base rule to find the logarithm to four decimal places. (2 points) log base nine of 0.877.
Given:
The value is [tex]\log_90.877[/tex].
To find:
The logarithm to four decimal places using the change of base rule.
Solution:
We have,
[tex]\log_90.877[/tex]
Using the change of base rule, we get
[tex]\log_90.877=\dfrac{\log_{10}0.877}{\log_{10}9}[/tex] [tex][\because \log_yx=\dfrac{\log_ax}{\log_ay}][/tex]
[tex]\log_90.877=\dfrac{-0.057000}{0.9542425}[/tex]
[tex]\log_90.877=-0.0597332439081[/tex]
Round the value to the four decimal places.
[tex]\log_90.877\approx -0.0597[/tex]
Therefore, the required value is -0.0597.
