[tex] \Large \underline{\tt Solution} :[/tex]
As, we have side of cube is 7 inches.
So, to find total surface area, we have a formula :
[tex] \underline{\boxed{\bf{Total \: surface \: area_{(cube)} = 6(side)^{2}}}}[/tex]
[tex] \tt : \implies Total \: surface \: area = 6 (7 \: inches)^{2}[/tex]
[tex] \tt : \implies Total \: surface \: area = 6 \times 49 \: inches^{2}[/tex]
[tex] \tt : \implies Total \: surface \: area = 294 \: inches^{2}[/tex]
[tex] \\ [/tex]
Hence, Total surface area of given cube is 294 inches².

Dos triángulos son semejantes, si sus ángulos son iguales y sus lados proporcionales. Verdadero o falso?
Answer: verdadero.
Step-by-step explanation:
En geometría se dice que dos figuras son semejantes si tienen la misma forma pero no necesariamente el mismo tamaño.
Ahora, lo que define la forma de un triángulo son sus ángulos, entonces si dos triángulos tienen los mismos ángulos, estos triángulos van a tener la misma forma.
Y los lados siendo proporcionales entre ellos (recordar que una relación proporcional es y = k*x) habla de la relación entre los tamaños de los dos triángulos.
Entonces si, "dos triángulos son semejantes, si sus ángulos son iguales y sus lados proporcionales" es verdadero.

If x + 3 /3 = y + 2/ 2 ,then x/ 3 =
Answer:
First solve for x
then substitute
Step-by-step explanation:
[tex]\frac{x+3}{3}= \frac{y+2}{2}[/tex]
[tex]6(\frac{x+3}{3}=\frac{y+2}{2})[/tex]
2x + 6 = 3y + 6
2x = 3y
[tex]x = \frac{3y}{2}[/tex]
If [tex]\frac{x+3}{3}= \frac{y+2}{2}[/tex] then [tex]\frac{x}{3}[/tex] =
[tex]x = \frac{3y}{2} /3 = \frac{y}3}[/tex]
Restaurants often slip takeout menus under Nina's apartment door. So far, Nina has collected

Not feeling ready yet? These can help:
Answer:
3 indian menus
Step-by-step explanation:
If we assume that the proportions would remain the same then we can use the values provided to calculate the number of indian menus. We can use the Rule of Three in this scenario, since it is a ratio problem and we are given 3 values and a variable. We simply multiply the diagonal values and divide by the remaining value to get the variable.
20 menus <====> 4 indian menus
15 menus <====> x indian menus
(15 * 4) / 20 = x
60 / 20 = x
3 = x

What is the area of JKLM?
Answer: 96in.^2
Step-by-step explanation:
Ok so first we need to find the missing width of figure NPQR and we can do that by dividing the area by the length to solve for height. so 294/21 is 14 so the missing side of NPQR is 14. With me so far? now since these figures are similar lets find out how similar. so 21/12= 1.75 so JKLM increased in dilation by 1.75 to get to NPQR. So now that we found the missing side from NPQR we can divide that by 1.75 to find the missing side of JKLM now. So 14/1.75= 8. So 8 is the missing side of JKLM. Now all we have to do is multiply. So 8*12= 96 or 96in.^2

Answer:
Option C & D
Step-by-step explanation:
__________________________________________________________
FACTS TO KNOW BEFORE SOLVING :-
Lets say there's an expression [tex]x^{\frac{a}{b} }[/tex] .
It can be also written it as → [tex](\sqrt[b]{x} )^{a}[/tex] and vice-versa.
__________________________________________________________
Lets come to the question.
In option A , [tex]7^{\frac{5}{7} }[/tex] can be also written as [tex](\sqrt[7]{7} )^{5}[/tex] . But it doesn't match with the other expression given. Hence they are not equivalent expressions.In option B , [tex]6^{\frac{2}{7} }[/tex] can be also written as [tex](\sqrt[7]{6} )^{2}[/tex] . But it doesn't match with the other expression given. Hence they are not equivalent expressions.In option C , [tex]5^{\frac{3}{2} }[/tex] can be also written as [tex](\sqrt{5} )^{3}[/tex]. Hence they are equivalent expressions.In option D , [tex](\sqrt[4]{81} )^{5}[/tex] can be also written as [tex]81^{\frac{5}{4} }[/tex] . Hence they are equivalent expressionsThus , Option C & D are correct.
The enrollment at a university increased from 1,000 students to 6,000 students over a 6-year period. What was the percent increase in enrollment over that time period?
Answer: 500%
Step-by-step explanation:
The percent increase is calculated as:
= (New number of students - Old number of students) / Old number of students * 100%
= (6,000 - 1,000) / 1,000 * 100%
= 5 * 100%
= 500%
