Step-by-step explanation:
Jose has 200 baseball cards. He has the Topps brand which he paid $1.50 each, Upper Deck Company brand which he paid $5.75 each, and Panini Group brand which he paid $2.60 each. He has 20 fewer Upper Deck Company brand than Panini Group brand. The total amount he spent was $589.50. How many of each brand of baseball cards does he have?
Answer:
Jose has 70 Panini, 50 Upper Deck, and 80 Topps cards.
Step-by-step explanation:
Given that Jose has 200 baseball cards, and he has the Topps brand which I have paid $ 1.50 each, Upper Deck Company brand which I have paid $ 5.75 each, and Panini Group brand which I have paid $ 2.60 each, and he has 20 fewer Upper Deck Company brand than Panini Group brand, and the total amount he spent was $ 589.50, to determine how many of each brand of baseball cards does he have, the following calculation must be performed:
100 Panini + 80 Upper Deck + 20 Topps = X
100 x 2.6 + 80 x 5.75 + 20 x 20 x 1.5 = X
260 + 460 + 30 = X
X = 750
80 Panini + 60 Upper Deck + 60 Topps = X
80 x 2.6 + 60 x 5.75 + 60 x 1.5 = X
208 + 345 + 90 = X
X = 643
60 Panini + 40 Upper Deck + 100 Topps = X
60 x 2.6 + 40 x 5.75 + 100 x 1.5 = X
156 + 230 + 150 = X
X = 536
70 Panini + 50 Upper Deck + 80 Topps = X
70 x 2.6 + 50 x 5.75 + 80 x 1.5 = X
182 + 287.5 + 120 = X
X = 589.5
Therefore, Jose has 70 Panini, 50 Upper Deck, and 80 Topps cards.
If 64x=82, what is the value of x?
Round your answer to three places.
Answer:
1.28
Step-by-step explanation:
First, you need to do 82/64, which will give you just x. Then, you need to round to three places. Without rounding it would be 1.28125
So with rounding it would be 1.28. Hope this helps and Happy learning!

What ideas do you have about what makes Anchorage, Alaska, cooler than Christchurch, New Zealand?
Answer:
You can explore a variety of things in Alaska. There are so many activities you could do such as visiting museums and hiking and tons more. The thing about this is that it is out in the wilderness which makes it more exciting and cooler to see nature more than it does in new zealand. The climate can be pretty chilly in Alaska but it is way much fun to see tons of glaciers. New zealand has eathquakes frequently whilst Alaska doesn't.
The length the height of a rectangular prism are 12 feet and 9 feet respectively. Determine the width of the rectangular prism whose surface area is 258 square feet
Answer:
Width = x feet = 1 feet
Step-by-step explanation:
Surface area of a rectangular prism = 2(lw +lh + wh)
Length = 12 feet
Width = x feet
Height = 9 feet
Surface area = 258 square feet
Surface area of a rectangular prism = 2(lw +lh + wh)
258 = 2{(12*x) + (12*9) + (x*9)}
258 = 2(12x + 108 + 9x)
258 = 24x + 216 + 18x
258 - 216 = 24x + 18x
42 = 42x
x = 42/42
x = 1 feet
Width = x feet = 1 feet
Please help me with this. And my teacher said to show your work so what do I have to do and she said on paper please help thank you!
Answer:
Step-by-step explanation:
V=H x W x L so 11.25= H (1.5) (2); 3H=11.25 so the height of one box is 3.75’
To find the volume of 5 stacked boxes multiply the volume of one box by 5.
5(3.75 x 1.5 x 2) which is 20.25 cubic feet.
can 5,7 and 13 make a triangle
Answer:
No
Step-by-step explanation:
5+7=12
12>13 X
13+5=18
18>13 YES
13+7=20
20>5 YES
If all equations were true, it would make a triangle, but since only 2 are true, it doesn't make a triangle.

Solve for a and b in the following circles:
A)
Given:
A quadrilateral inscribed in a circle.
To find:
The values of a and b.
Solution:
A quadrilateral inscribed in a circle. So, the quadrilateral is a cyclic quadrilateral.
We know that the sum of the opposite angles of a cyclic quadrilateral is 180 degrees.
[tex]a+79^\circ=180^\circ[/tex]
[tex]a=180^\circ-79^\circ[/tex]
[tex]a=101^\circ[/tex]
We know that the measure of arc is twice of measure of subtended angle on that arc.
[tex](110^\circ+b)=2(96^\circ)[/tex]
[tex]110^\circ+b=192^\circ[/tex]
[tex]b=192^\circ-110^\circ[/tex]
[tex]b=82^\circ[/tex]
Therefore, the value of a is 101 degrees and the value of b is 82 degrees.

. Which of the following is the correct algebraic representation of the translation below?
a. (x – 6, y – 5)
b. (x – 5, y – 6)
c. (x + 5, y + 6)
d. (x + 6, y + 5)
Answer:
D) (x+6, y+5)
Step-by-step explanation:
You can start with the top corner of triangle A
Then count up 5 units and right 6 units
Because you count vertically 5 units that means you're using the y-axis, And because you're counting up, than means the values are positive.
And because you count horizontally 6 units you're using the x-axis, And you are counting to the right so the values are positive.
Down vertically=Negative Y-axis Values. Up vertically=Positive Y-axis Values
Right horizontally=Positive X-axis values. Left horizontally=Negative X-axis Values

In a high school high jump contest, the height of clearing the bar ranged from 71 inches to 84 inches. The mean height was 76 inches and the standard deviation was 3.5 inches. What percent of the jumpers were in the group jumping below 79.5 inches
Step-by-step explanation:
Given data:
Range of jumps = 71 to 84 inches
Mean of jumps = 76 inches
standard deviation = 3.5
To calculate the percent of jumpers in the group jumping below 79.5 inches
Let us calculate the number of standard deviation in 79.5 inches
= 79.5/3.5
= 22.71 times
Answer:
84.1%
