Answer:
39 pounds is needed
Step-by-step explanation:
Given
Lawn Dimension: 78' by 93'
4 pounds fertilizer for 750ft² area
Required
Determine the amount needed for the given dimension
First, we need to calculate the area of the lawn
[tex]Area = 78' * 93'[/tex]
' means feet
So:
[tex]Area = 78ft * 93ft[/tex]
[tex]Area = 7254 ft^2[/tex]
Let the amount of fertilizer need be x
So, we have:
4 pounds = 750ft²
and
x = 7254ft²
Cross Multiply:
[tex]x * 750 = 4 * 7254[/tex]
[tex]x * 750 = 29016[/tex]
Solve for x
[tex]x = 29016/750[/tex]
[tex]x = 38.688[/tex]
[tex]x = 39[/tex] (approximated)
(c) is a circle of center O and radius R=2 cm, and A is a point such that OA=3 cm. There exist two circles of center A and tangent to (c). Construct these circles; calculate their radii
Given :
C) is a circle of center O and radius R=2 cm, and A is a point such that OA=3 cm.
There exist two circles of center A and tangent to (C).
To Find :
The radius of the new circles.
Solution :
Since, OA is 3 cm .
So, first circle with tangent to C if centre is at A is OA itself.
First radius, r = 3 cm.
And second circle is the on with radius , R = 3 + 2 = 5 cm.
Therefore, the radius of both the circles are 3 cm and 5 cm.
Hence, this is the required solution.
Which expression is equivalent to 13(6x +3) −p
Answer:
-p+78x+39
Step-by-step explanation:
In the accompanying diagram of a parallelogram
ABCD ,DC= 5x-18, BC=3x-6, AB=2x+12 find measure BC. Please help
Answer:
BC = 39
Step-by-step explanation:
Given:
DC = 5x - 18,
BC = 3x - 6,
AB = 2x + 12
Opposite sides of a parallelogram are equal.
Therefore:
AB = DC
2x + 12 = 5x - 18
Collect like terms
12 + 18 = 5x - 3x
30 = 2x
Divide both sides by 2
15 = x
x = 15
BC = 3x - 6
Plug in the value of x
BC = 3(15) - 6 = 45 - 6
BC = 39
Solve the system of equations below:
y = 3x - 5
y = -2x + 10
Answer: x=3
y=4
Step-by-step explanation:
since both equations equal y then you can just make them equal
so 3x-5=-2x+10
3x=-2x+15
5x=15
x=3
y=3(3)-5
y=9-5
y=4

On the coldest day of the year, the temperature at noon was 11℉. By midnight, the temperature had decreased by 15.5℉. What was the temperature at midnight? *
Answer: -4.5 ℉
Step-by-step explanation:
Given: On the coldest day of the year, the temperature at noon = 11℉
By midnight, the temperature had decreased by 15.5℉.
i.e. The temperature at midnight = Temperature at noon - 15.5℉
= 11℉ - 15.5℉
= (11-15) ℉
= -4.5 ℉
Hence, the temperature at midnight was -4.5 ℉.

7) 2.1x + 45.2 = 3.2 -8.4x
Answer:
x=-4
Step-by-step explanation:
brainliest please
Answer:
x=-4, Give brainliest please
Step-by-step explanation:
Step 1: Add 8.4x to both sides.
2.1x+45.2 = -8.4x +3.2
+8.4x +8.4x
10.5x+45.2=3.2
Step 2: Subtract 45.2 from both sides.
10.5x + 45.2 = 3.2
-45.2 -45.2
10.5x=−42
Step 3: Divide both sides by 10.5.
[tex]\frac{10.5x}{10\\}[/tex]=[tex]\frac{-42}{10}[/tex]
x=−4

-5 |3 + 4k| =-115
Answer:
-2k
Step-by-step explanation:
Answer:
5
To find:
k
Step-by-step explanation:
-5 (3 + 4k) = -115
-5 × 3 + -5 × 4k = -115
-15 - 20k = -115
-20k = -115 + 15
-20k = -100
k = -100/-20
k = 5

What unit is used to measure the density of a solid??
Answer:
Grams per cubic meter or g/cm3
Step-by-step explanation:
The answers vary, but they have the same format which is
density = mass/volume
For instance, if the mass is in grams and the volume is in cubic centimeters, then the density would be in grams/cm^3, where "cm^3" is the abbreviation of "cubic centimeters". We can read "grams/cm^3" out as "grams per cubic centimeter"

What is the value of x in the equation 3(4x-6) - 2x + 1 = 3 -(3x -6)
Answer: the answer is 21
Answer:
x = 2
Step-by-step explanation:
3(4x-6) -2x + 1 = 3 - (3x -6)
12x-18 -2x + 1 = 3-3x + 6
10x-17 = -3x+9
+17 +17
10x = -3x + 26
+3x +3x
13x = 26
/13 /13
x = 2
