For an area of 18m²,the amount of a fertilizer required is 675g.
a) how much is needed to fertilise 11m²?
b) what area will 862.5g fertilise?
Answer:
a) 412.5g
b)23m²
Step-by-step explanation:
a)18m²=675g
11m²=x
by cross multiplication,
18x=11×675
18x=7425
x=7425/18
x=412.5g
b)18m²=675g
y=862.5g
18×862.5=675y
15525=675y
15525/675=y
y=23m²
Answer:
Step-by-step explanation:
This is a rate problem so using ratios is a good way to calculate the answer for different areas or amounts
675 g per 18 m² 675/18 g/m²
a) How many grams for 11m²
675/18 g/m² = ??? / 11 m² i cross multiply 675 times 11 divide by 18
or more simply multiply both side by 11
solving for the ???
(675)(11) g m² / 18 m² = ??? g = 412.5 grams ( the m²/m² cancel)
b) what area can be fertilised with 862.5 g? again applying ratio
this time we know the g and want to calculate an unknown area
675 / 18 = 862.5 / ??? this will take one more step since the ??? is
in the denominator
18 / 675 = ??? / 862.5 I just inverted both sides
18m² / 675g = ??? / 862.5g again simply multiply both sides by 862.5g
(18m²)(862.5g) / (675g) = ??? this time the grams cancel leaving m²
??? = 23 m²
In Orlando Florida the high temperature was 85 degrees Fahrenheit on Saturday and 79 degrees Fahrenheit on Sunday what is the percent of change in the high temperature from Saturday to Sunday to the nearest whole percent
Answer:
[tex]7\%[/tex]
Step-by-step explanation:
Initial temperature = 85 degrees Fahrenheit
Final temperature = 79 degrees Fahrenheit
Percentage change in temperature is given by
[tex]\dfrac{|\text{Final temperature}-\text{Initial temperature}|}{\text{Initial temperature}}\times 100\%\\ =\dfrac{|79-85|}{85}\times 100\%\\ =7.05\approx 7\%[/tex]
The change in the high temperature from Saturday to Sunday is [tex]7\%[/tex].

Lateral surface area = 280 square inches
Step-by-step explanation:
Lateral surface area of a prism = (Perimeter of the base) × height of the prism
Perimeter of the base = 8 + 15 + 17
= 40"
Height of the prism = 7"
Therefore, Lateral surface area of the prism = 40 × 7
= 280 square inches

Is -1-126
(-12b - 6 + 9b - 18) equivalent to 2(b + 8)? Show your work.(please help)
Answer:
Well, -1-126 (-12b - 6 + 9b - 18) equals 378b + 2023.
Step-by-step explanation:
Subtract numbers:
−1−126 (−12−6+9−18)
−1−126 (−12−24+9)
Combine like terms:
−1−126 (−12−24+9)
−1−126 (−3−24)
Then you'll have to distribute:
−1−126 (−3−24)
−1+378 + 3024

Someone Pls solve both fast
Answer:
#1) x=38
#2) x=12
Step-by-step explanation:
For (1)
Since its a triangle we know that all 3 interior angles added up is gonna eqaul 180 degrees. So we already have 2 angles which are 21 and 17. You add those up and you’d get 38. Now since the final angles is unknown we can just make a simple equation of 38+x=180 since we know 2 angles and we need 1 more and a triangle is 180 degrees alli ddded up together. You’d get 142 for that angle. X is adjacent to that angle and they form a straight line so it also has to be 180. We got 1 side and so we subtract 180-142= 38. X will be 38.
For (2)
Since its 2 parallel lines cut by a transversal and we have two same side interior angles we know its gonna be supplementary Which means that both those angles added up will be 180. Now we have the two different angles so we add them up and solve for x. (10x+17)+(3x+7)= 180. Commbine like terms which will turn out to be 13x+24=180. Subtract 24 on both sides. 13x= 156. Solve for x by diving 13 on both sides which will lead to x= 12

Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
The given possible roots have the form that we'd get by using the quadratic formula, so let's start with that. Here the coefficients are {2, -6, 3}, and so the discriminant (b^2 - 4ac) is (-6)^2 - 4(2)(3), or 36 - 24 = 12.
Because the discriminant is positive we know immediately that there are two different real roots.

what is the discount? (tell me how you got your answer)
Answer:
the discount is 43.35 or the final price $7.65
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 51 × 85/100
Discount = 51 x 0.85
You save = $43.35
Final Price = Original Price - Discount
Final Price = 51 - 43.35

Answer:
Step-by-step explanation:
Triangles EFG and FGH are similar.
x/15 = 36/39
x/15 = 12/13
x = 15*12/13 = 180/13 ≈ 13.8 units
The required measure of x is given as 5.8 in the given triangle.
The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°.
What are similar triangles?Similar triangles are triangle that has a relationship as of some scale factor.
here,
From the figure,
From triangle GHF and triangle EGF
x / 15 = 15 / 39
x = 225 / 39
x = 5.8
Thus, the required measure of x is given as 5.8 in the given triangle.

Rank the following in order from most precise to least precise.
1500 grams
8.43 inches
1580 meters
5.426 seconds
Answer:
1st most = 8.43 inches
2nd most = 5,426 Seconds
3rd most = 1580 meters
4th most = 1500 grams
Step-by-step explanation:
8.43 inches = 0.7025 feet is most precise as it rounded to 0.7 feet it wouldn't be precise enough.
5,426 Seconds = 01:30:26. hrs mins sec can be converted.

The ratio sin 30° : tan 45º can be written in the form 1 : n.
Find the value of n.
Answer:
n = 2
Step-by-step explanation:
sin 30° = ½
tan 45° = 1
then
sin 30° : tan 45° = 1 : n
½ : 1 = 1 : n
n = 2
The value of n for the trigonometric expression will be n = 2
What is trigonometry?The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.
The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.
Given that the ratio sin 30°: tan 45º can be written in form 1: n. The value of n will be calculated as:-
sin 30° = ½
tan 45° = 1
Then,
sin 30° : tan 45° = 1 : n
½ : 1 = 1 : n
n = 2
