What is the value of the expression below? (4/5+3/5)+3.5x5
Answer:
18.9
Step-by-step explanation:
Start with parentheses.
4/5 + 3/5 = 7/5
Simplify 7/5, 7/5 = 1 2/5
Next numbers.
3.5 x 5 = 17.5
Add.

Question: Find the equation of the circle whose diameter is the segment between the intercepts of 3x + 4y = 24.
If you can answer this please explain the steps so I can understand, please and thank you so much!
Answer:
[tex](x-4)^2+(y-3)^2=25[/tex]
Step-by-step explanation:
We want to find the equation of a circle who diameter is the segment between the intercepts of the linear equation:
[tex]3x+4y=24[/tex]
Find the intercepts first. To find the x-intercept, let y = 0:
[tex]3x+4(0)=24\Rightarrow 3x=24\Rightarrow x=8[/tex]
The x-intercept is (8, 0).
To find the y-intercept, let x = 0:
[tex]3(0) +4y=24\Rightarrow 4y=24\Rightarrow y=6[/tex]
The y-intercept is (0, 6).
Since this segment is the diameter, its midpoint is our center.
Find the midpoint between (8, 0) and (0, 6). The midpoint formula is given by:
[tex]\displaystyle M=\left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right)[/tex]
Hence, the center of the circle is:
[tex]\displaystyle M=\left(\frac{8+0}{2}, \frac{0+6}{2}\right)=(4, 3)[/tex]
To find the radius of our circle, we can find the diameter and divide it by two.
The diameter is the length of the segment or the distance from (0, 6) to (8, 0).
Find the distance using the distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
So, the diameter of our circle is:
[tex]d=\sqrt{(8-0)^2+(6-0)^2}=\sqrt{64+36}=\sqrt{100}=10[/tex]
Therefore, the radius of our circle is 5.
The equation for a circle is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where (h, k) is the center and r is the radius.
Our center is (4, 3) and our radius is 5.
Therefore:
[tex](x-4)^2+(y-3)^2=25[/tex]
The cost of Cynthia's dinner is $15.20. She pays an additional tip that is 20% of the cost of the dinner. What is the best estimate for the amount of the tip?
Answer:
$3 (not exact, this is an estimate)
Step-by-step explanation:
Since it is estimate, it is not the exact amount. 20% is 1/5 and 15/5 = 3 so 1/5 or 20% is 3. the best estimate for the amount of tip is $3.
Find the distance between the points (6, –3) and (4,3).

A rancher planned to fence 6 1/2 acres of land to grow some experimental grasses. After he had finished fencing 4 3/4
acres of the land, it started snowing. How many acres of the land remained to be fenced?
Answer:
1 3/4 acres
Step-by-step explanation:
6 1/2 - 4 3/4 = the remaining acres to be fenced.
we can bring all numbers to "quarters" (1/4th) to be able to make that subtraction.
6 1/2 = 13/2 = 26/4
4 3/4 = 19/4
so, 26/4 - 19/4 = 7/4 = 1 3/4 acres still to be fenced.

109/396×10027.5%A computer store bought a program at a cost of $40 and sold it at a selling price of $32.5. Find the percent markdown (Rounded to a whole number) .
Answer:
answer is 18.76 percent.
Step-by-step explanation:
CP= $40
SP= $32.5
Markdown percent=?
now,
markdown %= CP-Sp/CP×100%
=7.5/40×100%
=750/40
=18.75%
The amount to be reduced is: $40 - $32.5 = $7.5
The percentage decrease is: (7.5 : 40) * 100 = 18.25%
