The amount of money Wally and Drake have left to save is equal to $29.96 if each one of them wanted to buy a telescope.
The amount of money left to be saved can be calculated by using an algebraic expression.
First, we determine the cost of two telescopes if each one of them wanted to buy a telescope to see the moons of Jupiter.
As the cost of one telescope is $62.48, the cost of two telescopes will be;
62.48 + 62.48 = 124.96
An algebraic expression can be given as;
95 + x = 124.96
where x is the money left to be saved.
Solving for x;
x = 124.96 - 95
x = 29.96
Hence, $29.96 is the amount left to be saved for each one of them to buy a microscope.

Please help me my mom is very upset and I’m grounded
look and solve this:
a) fractions; 15.3/3
b) yes, it is a rational number
b) A different pattern is made using 20 straight lines
and 14 arcs.
The straight lines and arcs are made from metal.
20 straight lines cost £12
cost of one straight line: cost of one arc = 2:3
Work out the total cost of metal in the pattern.
26.4
total cost of metal in the pattern is £24.6
What is ratio and proportion ?To compare two values is to use a ratio. A proportion is formed when two ratios have the same value. Choose whether the ratio is part-to-part or part-to-whole before you write it.
Calculation20 straight line cost £12
12 ÷ 20 = 0.6 per straight line
straight line : cost of one arc = 2:3
arc = 0.6 x (3/2) = 0.9
total = 12 + 14 x 0.9
= 12 + 12.6
= 24.6

Kaj needs to order some new supplies for the restaurant where she works. The restaurant needs at least 736 knives. There are currently 155 knives. If each set on sale contains 12 knives, what is the minimum number of sets of knives Kaj should buy?
The minimum number of sets of knives Kaj should buy if the restaurant needs at least 736 knives is 48. 4 sets of knives
How to find the minimum number of sets of knives Kaj should buy?Number of knives needed by the restaurant = at least 736 knivesNumber of knives currently available at the restaurant = 155 knivesEach set of knives = 12Number of sets of knives needed to buy = x155 + 12x ≥ 736
substract 155 from both sides12x ≥ 736 - 155
12x ≥ 581
divide both sides by 12x ≥ 581 / 12
x ≥ 48.41666666666666
Approximately,

n(-2) = 4/3
n(0) = 2/3
n(5) = -1
The function is n(x)= [tex]-1-\frac{1}{3}x+1\frac{2}{3}[/tex]
The function is an equation which expression the relationship between one variable and another variable. If one variable is independent variable then another variable will be dependent variable.
The function is n(x)= [tex]-1-\frac{1}{3}x+1\frac{2}{3}[/tex] when x= -2,0 and 5
Here we have to substitute the value of x in the given function
n(-2) = -1-(1/3)(-2)+5/3
= -1+(2/3)+5/3
= 4/3
n(0) = -1-(1/3)(0)+5/3
= -1+(5/3)
= 2/3
n(5) = -1-(1/3)(5)+5/3
= -1-(5/3)+(5/3)
= -1
Hence, the result of the function n(x)= [tex]-1-\frac{1}{3}x+1\frac{2}{3}[/tex] when x = -2,0 and 5

How to find the area in terms of the given dimensionsGiven data
length of fence = 1040 ft
length if the pasture = L
width of the pasture = x
Expression for length L in terms of x
from the figure we can see that the fenced part is 3 sides which include 2 widths and 1 length. So we represent this with the expression below
L + x + x = 1040
L + 2x = 1040
L = 1040 - 2x
Expression for the area of the pasture in terms of L and x
Area of the pasture, A = L * x
A = Lx
Expression for the area of the pasture in terms of x only

Which term of the arithmetic sequence 7, 3, -1, -5, ... is -385?
99th term of the given arithmetic sequence 7, 3, -1, -5, ... is -385.
We are provided with the arithmetic sequence mentioned below;
7, 3, -1, -5, ................. -385
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n−1)d
where [tex]a_{1}[/tex] is the first term, [tex]a_{n}[/tex] is the nth term and d is the difference between a term and its previous term.
With the help of provided arithmetic sequence we can write;
[tex]a_{n}[/tex] = -385
[tex]a_{1}[/tex] = 7
d = difference between a term and its previous term = 3 - 7 = -4
Put these values in equation 1 , we will get
-385 = 7 + (n-1) (-4)
392 = 4n -4
4n = 396
n = 99

The dimensions of the region which enclose the maximum area is a side of 162 feet and vertical segment of 108 feet
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the side parallel to the vertical segment and y represent the other side. If the farmer has 648 feet of fencing, hence:
x + x + y + y + x = 648
3x + 2y = 648
y = 324 - 1.5x
Area (A) = xy
A = xy
A = x(324 - 1.5x)
A = 324x - 1.5x²
The maximum area is at A' = 0, hence:
A' = 324 - 3x
324 - 3x = 0
3x = 324
x = 108 feet
y = 324 - 1.5(108) = 162 feet

Answer: c
Step-by-step explanation:
The solution set for the inequality is p > -9.4. See attachment below for the graph.
How to Graph the Solution Set for an Inequality?An open circle is used when the inequality sign involved is ">" or "<". That is, it is used for numbers that are less than or greater than.
An arrow shaded to the right means the solution set is greater than a given value, while an arrow shaded to the left means the solution set includes all values that are less than a given value.
Given the inequality, p + 3.6 > −5.8, solve for p:
p + 3.6 > −5.8
Subtract 3.6 from both sides
p + 3.6 - 3.6 > -5.8 - 3.6
p > -9.4
Thus, the solution set would be all the values that are greater than -9.4. The graph is shown below.

Grayce has three diamonds that weigh 0.275 g each. Morgan has two diamonds that weigh 0.412 g each. Who has more grams of diamonds?
Grayce has 0.825 g of diamonds and Morgan has 0.824 g of diamonds. Grayce has more grams of diamonds
Calculating weightsFrom the question, we are to determine the person that has more grams of diamonds
From the given information,
"Grayce has three diamonds that weigh 0.275 g each"
and
"Morgan has two diamonds that weigh 0.412 g each"
Thus,
The total mass of Grayce's diamonds is 3 × 0.275 g
3 × 0.275 g = 0.825 g
Also,
The total mass of Morgan's diamonds is 2 × 0.412 g
2 × 0.412 g = 0.824 g
Since 0.825 is greater than 0.824,
Then,
Grayce has more grams of diamonds.
