Answer:
Step-by-step explanation:
The base and height will be the two equal sides of the isosceles right triangle.
⇒ b = h = x cm
[tex]Area \ of \ triangle = \dfrac{1}{2}bh[/tex]
[tex]\dfrac{1}{2}bh = 72 \ cm^{2}[/tex]
[tex]\dfrac{1}{2}*x*x=72\\\\\\\dfrac{1}{2}*x^{2}=72\\\\\\x^{2}=72*2\\\\x^{2}=144\\\\Take \ square \ root,\\\\\sqrt{x^{2}}=\sqrt{144}\\\\x = \sqrt{12*12}\\\\x = 12 cm[/tex]
Hypotenuse² = b² + h²
= 12² + 12²
= 144 + 144
= 288
hypotenuse = √288
= 16.97 cm
Answer:
[tex]\large{\boxed{\sf Hypotenuse = 16.97\ cm }}[/tex]
Step-by-step explanation:
Here it is given that the area of a right isosceles ∆ is 72 cm² . Let us assume that each equal side is x . Therefore the height and the base of the ∆ will be same that is x .
[tex]\sf\qquad\longrightarrow Area =\dfrac{1}{2}(base)(height)\\ [/tex]
[tex]\sf\qquad\longrightarrow 72cm^2=\dfrac{1}{2}(x)(x)\\[/tex]
[tex]\sf\qquad\longrightarrow x^2= 144cm^2\\ [/tex]
[tex]\sf\qquad\longrightarrow x =\sqrt{144cm^2}\\ [/tex]
[tex]\sf\qquad\longrightarrow \pink{x = 12cm }[/tex]
Hence we may find hypotenuse using Pythagoras Theorem as ,
[tex]\sf\qquad\longrightarrow h =\sqrt{ p^2+b^2} [/tex]
Here p = b = 12cm ,[tex]\sf\qquad\longrightarrow h =\sqrt{ (12cm)^2+(12cm)^2}\\[/tex]
[tex]\sf\qquad\longrightarrow h =\sqrt{144cm^2+144cm^2}\\[/tex]
[tex]\sf\qquad\longrightarrow h =\sqrt{288cm^2}\\[/tex]
[tex]\sf\qquad\longrightarrow \pink{ hypotenuse= 16.97cm }[/tex]
Hence the hypotenuse is 16.97 cm .

Shannon’s mom took her to dinner for her birthday. Their dinners totaled $80 and sales tax was 5%. If Shannon’s mom left a 20% tip on the cost of their dinners before tax, how much money did she spend in all?
Answer:
100 dollars.
Step-by-step explanation:
First you multiply 80 by 5% which is 4. Then you multiply 80 by 20% which is 16. Then you add it all together which gives you $100.
Michelle bought five packs of crayons for $16.25 What is the cost of a pack of crayons, in dollars, if all the packs cost the same?
Answer:
Michelle bought a pack of crayon for $3.25
Step-by-step explanation:
Number of packs = 5
The cost of a pack of crayons =
(Cost of 5 packs of crayon) / (number of packs of crayons)
The cost of a pack of crayons = ($16.25 ) / 5
The cost of a pack of crayons = $16.25 / 5
The cost of a pack of crayons = $3.25
Solve:
q-6/5=1/12
A. 7/17
B. 7/60
C. 1 17/60
D. -1 17/60
Answer:
The choice C .
[tex]1 \frac{17}{60} [/tex]
Step-by-step explanation:
[tex]q - \frac{6}{5} = \frac{1}{12} \\ \\ q = \frac{1}{12} + \frac{6}{5} \\ \\ q= \frac{5}{60} + \frac{72}{60} = \frac{77}{60} = 1 \frac{17}{60} [/tex]
Answer:
q = 1 [tex]\frac{17}{60}[/tex]
Step-by-step explanation:
q - [tex]\frac{6}{5} = \frac{1}{12}[/tex]
Add [tex]\frac{6}{5}[/tex] to both sides.
q = [tex]\frac{1}{12} + \frac{6}{5}[/tex]
The least common multiple of 12 and 5 is 60. Convert [tex]\frac{1}{12}[/tex] and [tex]\frac{6}{5}[/tex] to fractions with denominator 60.
q = [tex]\frac{5}{60} + \frac{72}{60}[/tex]
Since [tex]\frac{5}{60}[/tex] and [tex]\frac{72}{60}[/tex] have the same denominator, add them by adding their numerators.
q = [tex]\frac{5 + 72}{60}[/tex]
Add 5 and 72 to get 77.
q = [tex]\frac{77}{60}[/tex]
Add the 1 and you get:
1 [tex]\frac{77}{60}[/tex]

Santosh brought 300 dotpens for Rs 4500. He sold 200 of them at a loss of 5%. At what rate should he sell the remaining dotpens so as to gain 10% an the whole.
Santosh must sell the remaining dotpens with a surplus of 40 % to gain 10 % on the whole.
How to calculate the gain of selling dotpensWe know that Santosh sold 200 dotpens with a loss of 5 % and he must sell the remaining dotpens with an unknown surplus in order to obtain 10 % of the whole. The situation can be represented by the following expression:
[tex]-0.05\cdot (\frac{4500}{300} )\cdot (200) + x\cdot \left(\frac{4500}{300} \right)\cdot (100) = 0.10\cdot (4500)[/tex] (1)
[tex]-150+1500\cdot x =450[/tex]
[tex]x = 0.4[/tex]
Santosh must sell the remaining dotpens with a surplus of 40 % to gain 10 % on the whole. [tex]\blacksquare[/tex]

Answer:
If the mayor knows the area and length of the base of the flower garden, she can divide the area by the length to determine the height
Step-by-step explanation:
Area = Length • Height
divide both sides by Length
Area/Length = Height
Answer:
First, she starts with the formula for area for the specific shape in the problem. Then, substitute the area and the base into the formula. Finally, she can solve the resulting equation for the height.
