Multiply both sides by 4
4xt/4> 4x7
Reduce the number 4
T>4x7
Multiply the 4x7
And the answer is t> 28
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
The original amount of money on the gift card was $45. After buying 8 cups of coffee, the remaining balance was $25.
<u>First, we need to calculate the unitary value of each cup of coffee:</u>
Unitary cost= 20/8= $2.5
<u>Now, we can structure the remaining balance formula (A):</u>
A= 45 - 2.5x
x= cup of coffee
<u>After 2 cups:</u>
A= 45 - 2.5*2
A= 40
Answer:
87.5% of the cube's original volume has melted away.
Step-by-step explanation:
So, you will need to calculate the volume of the initial ice cube, as well as the melted ice cube to find the percentage of the volume.
Original Cube
V=l³
V=2³
V=8
Melted Cube
V=1³
V=1
Next, we need to find how much melted by subtracting the new from the old.
8-1=7
Next, we need to find the percentage that melted by dividing the volume that melted from the original volume. Then multiply the decimal by 100 to get the percentage value.
7/8=0.875
0.875×100=87.5
87.5% of the cube's original volume has melted away.
Answer:
36 units²
Step-by-step explanation:
If you separate the figure into a triangle and a rectangle
A=bl for rectangles
the rectangle dimensions are 4 by 6 or 4(6)=24
A=bh/2
the triangles dimensions are 6 by 4 so
(6*4)/2=24/2=12
24+12=
36 units²
