and sorry for the low points i dont have a lo
Answer:
2
Step-by-step explanation:
To find the slope given two points you do [tex]\frac{y2-y1}{x2-x1}[/tex]
so we just plug in the y values and x values
[tex]\frac{-7-5}{-2-4}[/tex]
[tex]-7-5=-12[/tex]
[tex]-2-4=-6[/tex]
[tex]\frac{-12}{-6} =2[/tex]
Therefore the slope is 2

Sandy went to her local zoo that featured 10 lion exhibits. If the zoo features 20 exhibits in total, then what percent of the zoo's exhibits feature lions? Round your answer to the nearest whole number if necessary.
Answer:
Answer is 50%
Step-by-step explanation:
Zoo that featured for 10 lion exhibits.
And Zoo featured for 20 exhibits in total.
Now, let's find the percent of zoo's exhibit featured for lions.
We can write it as
x=[tex]\frac{10}{20} *100%[/tex]
Simplify it
x=50%
decrease 50 by 60% please
Answer:
20
Step-by-step explanation:
60% of a hundred is 60, and since 50 is half of that I just halfed sixty too, so decrease 50 by 30
David is considering changing his car to one which used liquefied
petroleum gas (LPG). A litre of LPG costs £0.62 and a litre of petrol
costs £1.29. What is the cost of a litre of LPG as a percentage of the
cost of a litre of petrol (give your answer to the nearest whole number)?
Answer:
48%
Step-by-step explanation:
A liter of LPG costs £0.62
A liter of petrol costs £1.29.
Therefore,
The cost of a liter of LPG as a percentage of the cost of a liter of petrol is calculated as:
Cost of LPG/ Cost of Petrol × 100
= £0.62/£1.29 × 100
= 48.062015504%
Approximately to the nearest whole number = 48%

A restaurant chef was ordering supplies. He ordered 9 pounds of beef at 7.53 per pound, 9 pounds of potatoes at $6.45 a pound and 4 pounds of carrots at $6.23 per pound. He estimates that this will make 27 meals. If he charges 39.53 per meal how much profit will he make
Answer:
916.57 pounds
Step-by-step explanation:
Cost of beef = 7.53 pounds × 9
= 67.77 pounds
Cost of potatoes = 6.45 pounds × 9
= 58.05 pounds
Cost of carrots = 6.23 pounds × 4
= 24.92 pounds
Total cost = 67.77 pounds + 58.05 pounds + 24.92 pounds
= 150.74 pounds
Total revenue = 27 meals × 39.53 pounds
= 1067.31 pounds
Total profits = Total revenue - Total cost
= 1067.31 pounds - 150.74 pounds
= 916.57 pounds
how do i solve this ?
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Angle sum property of a Triangle.
hence,
==> 4x + 8° + 60° + 60° = 180
==> 4x + 128° = 180°
==> 4x = 180 - 128
==> 4x = 52°
==> x = 52/4
==> x = 13°
hence the value of x = 13 °
36/2^5 over 8+7x(3+11)
Answer:
119.25
Step-by-step explanation:
36/32 simplified is 9/8.
8 + 7(3+11), I'm assuming it's not x.
8 + 7(14) = 106
(9/8)/106 = 9/8*106 = 954/8 = 119.25
Hope this helps, lmk if the "x" is actually a variable instead of multiplication :)
−2x=x2−6 Rewrite the equation by completing the square.
Answer:
(x + 1)² = 7
Step-by-step explanation:
Given:
-2x = x² - 6
We'll start by rearranging it to solve for zero:
x² + 2x - 6 = 0
The first term is already a perfect square so that's fine. Normally, if that term had a non-square coefficient, you would need to multiply all terms a value that would change that constant to a perfect square.
Because it's already square (1), we can simply move to the next step, separating the -6 into a value that can be doubled to give us the 2, the coefficient of the second term. That value will of course be 1, giving us:
x² + 2x + 1 - 1 - 6 = 0
Now can group our perfect square on the left and our constants on the right:
x² + 2x + 1 - 7= 0
x² + 2x + 1 = 7
(x + 1)² = 7
To check our answer, we can solve for x:
x + 1 = ± √7
x = -1 ± √7
x ≈ 1.65, -3.65
Let's try one of those in the original equation:
-2x = x² - 6
-2(1.65) = 1.65² - 6
- 3.3 = 2.72 - 6
-3.3 = -3.28
Good. Given our rounding that difference of 2/100 is acceptable, so the answer is correct.

Which method presented by teams in problem 8-48 seemed able to help find the area of other regular polygons? Discuss this with your team. Then find the area of the two regular polygons below. If your method does not work, switch to a different method. Assume c is the center of each polygon.
Create a poster or transparency that shows the two different methods that your team used to find the area of the regular hexagon in part (b) of problem 8-43. Then, as you listen to other teams present, look for strategiesthat are different than yours. For each one, consider the questions below. •Which geometric toolsdoes this method use? •Would this method help find the area of other regular polygons (like a pentagon or 100-gon)?8-45. Which method presented by teams in problem 8-44 seemed able to help find the area of other regular polygons? Discuss this with your team. Then find the area of the two regular polygons below.

Answer:
x = 5
Step-by-step explanation:
To get the value of x we will use similar triangles as shown;
AT/AG = AB/AC
9/3 = x+10/3x-10
Cross multiply
3(x+10) = 9(3x-10)
3x + 30 = 27x - 90
Collect like terms
3x - 27x = -90 - 30
-24x = -120
x = 120/24
x = 5
Hence the value of x is 5

Answer:
Step-by-step explanation:
Are the volumes equal? No, so throw out the first and the last one.
Is the volume of the pyramid greater than the volume of prism?
No, so throw out the third one
so by inspection it must be the remaining one
or mathematically
vol pyramid = (1/3)(base)(height)
vol prism = (base)(height)
vol pyramid / vol prism
(1/3)(base)(height) / (base)(height) = 1/3
