As an estimation we are told 5 miles is 8 km.
Convert 88 km to miles.
Answer:
8 km = 5 miles
88km= (5×88)/8 miles = 55 miles
55 miles is the right answer.How much of an alloy that is 10% copper should be mixed with 600 ounce of an alloy that is 70%copper in order to get an alloy that is 30%copper?
Answer:
1200 ounces
Step-by-step explanation:
How much of an alloy that is 10% copper should be mixed with 600 ounce of an alloy that is 70%copper in order to get an alloy that is 30%copper?
Let us represent
Number of ounce of 10% copper = x
Hence, our Equation =
x × 10% + 600 × 70% = (x + 600) × 30%
0.1x + 420 = (x + 600)0.3
0.1x + 420 = 0.3x + 180
Collect like terms
0.3x - 0.1x = 420 - 180
0.2x = 240
x = 240/0.2
x = 1200 ounces
6) Walmart and Target are having deals on Barbie dolls. Walmart is selling 8 dolls for $120 and Target is selling 6 dolls for $102. Which store has the better deals on Barbie dolls? Explain how you know
Answer:
Walmart has the better deal
Step-by-step explanation:
If you do $120/8 dolls you get $15 for each doll at Walmart. If you do $102/6 dolls you get $17 for each doll. You know $15 is less than $17 making it cheaper and a better deal. Target's dolls are $2 more than Walmart. $17-$15=$2

A. focus
B. vertex
C. directrix
D. center
Answer: B.) vertex
Step-by-step explanation:
On a parabola, the extreme point (which is the highest, lowest, or farthest point left or right) is called the ''Vertex.''
What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
To find the extreme point of the parabola.
Now, We know that;
Every parabola has a shape of an U,
Then, they have an extreme point. Depending if the parabola has the formula y = ax² + bx + c or x = ay² + by + c (where a, b and c are constants) and what value constant a has, what kind of extreme point the parabola have.
Hence, On a parabola, the extreme point (which is the highest, lowest, or farthest point left or right) is called the ''Vertex.''

Which compound inequality is represented by the graph?
(A.) -2
(B.) -2_
(C.) x<-2 or x_>4
(D.) x_<-2 or x>4
Answer: Choice C
[tex]x < -2 \ \text{ or } \ x \ge 4[/tex]
========================================================
Explanation:
The blue portion on the left is represented by [tex]x < -2[/tex] as it describes values smaller than -2. Notice the open hole at -2 which indicates we do not include this value. So that's why we go with [tex]x < -2[/tex] instead of [tex]x \le -2[/tex]
The blue portion on the right is represented as [tex]x \ge 4[/tex] describing values that are equal to 4, or larger than 4.
So overall, the entire graph visually represents x values such that [tex]x < -2 \ \text{ or } \ x \ge 4[/tex]
Side note: the "or" means we pick one region or the other, but not both regions at the same time.

Gilligan sees a ship coming close to the shore he's standing on. He wants to
determine the distance (SD) from the ship to the shore. He walks 130 ft along the
shore from point D to point C and marks that spot. Then he walks 23 ft further and
marks point B. He turns 90 and walks until his location (point A), point C, and point
S are collinear.
o
Answer the following questions making sure to show all your work.
(a) Can Gilligan conclude that triangle ABC and triangle SDC are similar? Why or why
not?
(b) Suppose AB = 90 ft. What can Gilligan conclude about the distance of the ship
from the shore? Explain.
The triangles ABC and SDC are similar triangles
Gilligan can conclude that triangles ABC and SDC are similarGilligan can conclude that the distance of the ship from the shore is 509 ftHow to determine if the triangles are similarFrom the question, we understand points S, C and A are collinear, while line AB and SD are vertical and parallel lines at the either sides of point C.
Hence, Gilligan can conclude that triangles ABC and SDC are similar
How to calculate the distance SD
To do this, we make use of the following equivalent ratio
[tex]SD : 130 = AB : 23[/tex]
Substitute 90 for AB
[tex]SD : 130 =90 : 23[/tex]
Express as fraction
[tex]\frac{SD}{130} =\frac{90}{ 23}[/tex]
Make SD the subject
[tex]SD =\frac{90}{ 23} * 130[/tex]
[tex]SD =509[/tex]
Hence, Gilligan can conclude that the distance of the ship from the shore is 509 ft

Loris has one of each of the following colours of felt-tip pen in her pencil case:
red (R) blue (B) yellow (Y) green (G) purple (P)
She pulls out two random pens.
How many different combinations of pairs of colours are there?
there are 10 different combinations of pairs of colors.
What is the combination?Combinations are ways to choose elements from a collection in mathematics where the order of the selection is irrelevant. Let's say we have a trio of numbers: P, Q, and R. Then, combination determines how many ways we can choose two numbers from each group.
Given, Loris has one of each of the following colors of felt-tip pen in her pencil case: red (R) blue (B) yellow (Y) green (G) purple (P) She pulls out two random pens.
from the formula of combination;
total combination ⁿCₓ = [tex]\frac{n!}{(n-r)! * r!}[/tex]
Where, n = total numbers
r = desired number out of total
In our case
n = 5 and r = 2
Thus, the Total combination = ⁵C₂
Total combination = 5! / (3! *2!)
total combination = 5 *4 /2 = 10
therefore, There are ten distinct ways to pair the colors together.

A quadratic function, f(x) = x2 + bx + 9, is such that there is only one real root. Which of the following are possible values of b?
I. b = 2
II. b = 6
III. b = -6
IV. b = -2
A. I, II, III, and IV
B. I and IV only
C. II and III only
D. I only
Answer:
C
Step-by-step explanation:
Remember that we can use the discriminant to determine the amount of roots that a quadratic function has.
If the determinant equals 0, then we only have one real root.
Our function is given by:
[tex]f(x)=x^2+bx+9[/tex]
Then the discriminant will be:
[tex]\Delta = b^2-4(1)(9)=b^2-36[/tex]
We only have one real root, thus our discriminant must be 0:
[tex]0=b^2-36[/tex]
Solve for b:
[tex]b^2=36[/tex]
Thus:
[tex]b=\pm 6[/tex]
The answer is both II and III.
The final answer, then, is C.
