Answer:
Step-by-step explanation:
speed = distance/time
so renaldo speed = 3.2/0.5 = 6.4miles/hr (since time taken is 1/2 hr)
now after 1 hr of his appoinment i.e at 5:30pm he took bus whose speed is same as before i.e 6.4 miles/hr
now time taken to cover this 4.8 miles = 4.8/6.4 = 3/4 hr (since time = distance /speed )
3/4 hr = 3/4 * 60 = 45 minutes
so he reached at 6:15pm . so he will be on time.
Umar has 5 dimes in his right pocket and three dimes in his left pocket how much money does Omar have? What is the hidden question?
Answer:
he has 80 cents
Step-by-step explanation:
dime=10 cents
I'm guessing that the hidden question is how many dimes does Omar have? because this is the first thing I asked myself when solving this equation.
So how many dimes does Omar have?
5 + 3 = 8
Now we know that one dime = 10 cents, so to find the amount of money in cents, all we need to do is multiply 8 * 10
8 * 10 = 80
Omar has 80 cents

Answer:
[tex]3x^2-3x-60[/tex]
Step-by-step explanation:
Given: [tex]3(x+4)(x-5)[/tex]
Let's use the distributive property to multiply [tex](x+4)(x-5)[/tex] together since they are right next to each other. We can use the FOIL method.
[tex](x+4)(x-5)\\x^2-5x+4x-20\\x^2-x-20[/tex]
Now that we simplified that, we still have to multiply everything by the value of [tex]3.[/tex]
[tex]3(x^2-x-20)\\3x^2-3x-60[/tex]
Now, you could have left the answer as [tex]3(x^2-x-20)[/tex] since it is factored, but the problem wants us to find the product, so we need to completely simplify.
A classmate plotted the following points:
A(-3, 2), B(-1, 4), and C(1, 2).
Where should the classmate plot point
D so that the quadrilateral formed has
perpendicular sides?
Answer:
D(-1,0)
Step-by-step explanation:
Plot points A(-3, 2), B(-1, 4), and C(1, 2) on the coordinate plane (see attached diagram).
Two sides AB and BC are of equal length and are perpendicular, because
[tex]AB=\sqrt{(-3-(-1))^2+(2-4)^2}=\sart{(-2)^2+(-2)^2}=\sqrt{4+4}=2\sqrt{2}\ units\\ \\BC=\sqrt{(-1-1)^2+(4-2)^2}=\sart{(-2)^2+2^2}=\sqrt{4+4}=2\sqrt{2}\ units\\ \\\text{Slope AB}=\dfrac{4-2}{-1-(-3)}=\dfrac{2}{2}=1\\ \\\text{Slope BC}=\dfrac{2-4}{1-(-1)}=\dfrac{-2}{2}=-1\\ \\\text{Slope AB}\cdot \text{Slope BC}=1\cdot (-1)=-1\Rightarrow \text{lines AB and BC are perpendicular}[/tex]
If the quadrilateral ABCD has all sides perpendicular, then ABCD is a square. The diagonals of the square bisects each other. Find the coordinates of the point of intersection of these diagonals. This is the midpoint of segment AC:
[tex]x=\dfrac{-3+1}{2}=-1\\ \\y=\dfrac{2+2}{2}=2[/tex]
If point O(-1,2) is the point of intersection of diagonals, then it is the midpoint of the diagonal BD. Find coordinates of point D:
[tex]x_O=\dfrac{x_B+x_D}{2}\Rightarrow -1=\dfrac{-1+x_D}{2},\ -1+x_D=-2,\ x_D=-1\\ \\y_O=\dfrac{y_B+y_D}{2}\Rightarrow 2=\dfrac{4+y_D}{2}, 4+y_D=4,\ y_D=0[/tex]
Thus, D(-1,0)

7 + 1 = 88/3 is the answer.So far, Carmella has collected 14 boxes of baseball cards. There are 315 cards in each box. Carmella estimates that she has about 3,000 cards, so she buys 6 albums that hold 500 cards each.
a. Will the albums have enough space for all of her cards? Why or why not?
b. How many cards does Carmella have?
c. How many albums will she need for all of her baseball cards?
Answer:
4410 cards, 9 albums
Step-by-step explanation:
Number of cards in a box = 315
Number of boxes = 14
b) Total number of cards = Number of boxes × Number of cards in 1 box
=[tex]315\times 14 = 4410[/tex]
a) Carmella estimated she had 3,000 cards so she bought a 6 album of 500 cards.
No, 6 albums are not enough as she estimated wrong number of cards. There are total of 4410 cards but she estimated it to be 3000 cards.
c) Total number of albums required = [tex]\displaystyle\frac{\text{Total number of cards}}{\text{Number of card 1 album can hold}}[/tex]
[tex]=\frac{4410}{500} = 8.82 \approx 9[/tex]
Thus, she will require 9 albums to put all her cards.

A 21-foot rope is cut into 2 pieces. Seven less than three times the length of the longer rope piece x is five times the length of the shorter piece, which is (21 − x) ft. Find the length of the longer rope piece x In ft
Answer:
The length of the longer rope piece is 14 ft
Step-by-step explanation:
Let
x -----> the longer piece
y ----> the shorter piece
we know that
The sum of the longer piece plus the shorter piece must be equal to the length of the original piece
x+y=21
y=(21-x) -----> equation A
3x-7=5y ----> equation B
substitute equation A in equation B and solve for x
[tex]3x-7=5(21-x)\\3x-7=105-5x\\5x+3x=105+7\\8x=112\\x=14\ ft[/tex]
therefore
The length of the longer rope piece is 14 ft

⇒ 6(4x − 10) = 84
Now, We can simplify as;
6(4x - 10) = 84
24x - 60 = 84
24x + (-60) = 84
24x - 60 + 60 = 84 + 60
24x = 144
24x/24 = 144/24
x = 6
Therefore, Solution is,
⇒ x = 6

10. The values of x and y vary directly, and
when x = 48, y = 36. Find the value of x when
y = 18.
Answer:the answer is 24
Step-by-step explanation:
Because when 18 is the half of 36 so 24 is the half of 48
Given x and y vary directly with constant ratio 1.33, the value of x when y equals 18 is 23.94.
Explanation:The subject question deals with direct variation, a concept in Mathematics. When two variables vary directly, a change in one variable results in a proportionate change in the other variable. If x and y vary directly, it means the ratio of x to y is constant.
From the problem, x = 48 when y = 36. Therefore, the ratio of x to y is 48/36 = 1.33.
To find the value of x when y = 18, simply multiply the constant ratio (1.33) by the new value of y.
So, x = 1.33 * 18 = 23.94

Which diagram shows AABC rotated 120° counterclockwise about B?
Answer:
second one diagram rotated 120
In a 120° counterclockwise rotation about point B, diagram AABC would shift each point along a circular path 120° in a counterclockwise direction around point B. The positions of points A and C would change, while point B would stay as it is. The correct diagram would reflect these changes.
Explanation:Without a specific diagram to refer to, I can provide only a general explanation of how to determine the diagram that represents AABC rotated 120° counterclockwise about point B.
Rotations in a plane are performed counterclockwise with a positive degree measure. So, a 120° counterclockwise rotation about a fixed point B would take every point on triangle AABC and shift it along a circular path 120° in a counterclockwise direction around point B. The result would be a new triangle A'B'C'. If point B is the origin of rotation, it would remain unchanged. However, points A and C would change their positions after the rotation.
To determine the correct diagram, you would look for a triangle that has been shifted around point B in a counterclockwise direction with positions of points A and C reflecting a 120° rotation.

Answer:
[tex]y= \frac{-5}{2}x-1[/tex]
Step-by-step explanation:
the line equation is 5x + 2y = 12
Solve for y to find out slope m
y=mx+b
[tex]5x + 2y = 12[/tex]
Subtract 5x from both sides
[tex]2y =-5x+12[/tex]
Divide both sides by 2

Ayodele received a raise in her hourly pay, from $24.50 to $25.48. Find the percent change.
Answer:
4%
Step-by-step explanation:
The raise in her hourly pay is
$25.48-$24.50 =$0.98
Cross multiplying (rule of three)
24.50------100%
0.98--------x%
and so, x= 0.98*100/24.5 = 4%
Answer: The required percent change is 4%.
Step-by-step explanation: Given that Ayodele received a raise in her hourly pay, from $24.50 to $25.48.
We are to find the percent change.
The percent change is given by
[tex]p=\dfrac{\textup{increse in the amount}}{\textup{original amount}}\times100\%.[/tex]
In the given situation, we have
[tex]\textup{increase in the amount}=\$(25.48-24.50)=\$0.98.[/tex]
Therefore, the percent change is given by
[tex]p=\dfrac{0.98}{24.50}\times100\%=\dfrac{98}{24.50}\%=4\%.[/tex]
Thus, the required percent change is 4%.

How many 2/3-cup servings are in 6 cups of cereal?
Answer: 9
Step-by-step explanation:
6 divided by 2/3 = 9
In 6 cups of cereal, there are 9 servings of 2/3 cup.
Explanation:To find out how many 2/3-cup servings are in 6 cups of cereal, we need to divide the total cups of cereal by the size of each serving. In this case, we divide 6 by 2/3. To divide a whole number by a fraction, we can multiply the whole number by the reciprocal of the fraction. The reciprocal of 2/3 is 3/2, so we have 6×3/2 = 9 cups in total. Therefore, there are 9 servings of 2/3 cup in 6 cups of cereal.
