Turn 276% into a mixed number

AlladinOne [14]

Mixed number is (wholenumber)+(properfraction)
a proper fraction is a/b where a<b and b≠0

so

percent means parts out of 100
x%=x/100

so
276%=
276/100=
200/100+76/100=
2+76/100=
2+38/50=
2+19/25

${a}^{ \frac{m}{n} } = \sqrt[n]{ {a}^{m} }$

Convert the expressions from radical to exponent form.

$9 \sqrt[4]{ {t}^{3} } \times 7 \sqrt[3]{ {t}^{2} } \\ 9( {t}^{ \frac{3}{4} } ) \times 7( {t}^{ \frac{2}{3} } )$

Simplify the expression by multiplying.

$63( {t}^{ \frac{3}{4} } \times {t}^{ \frac{2}{3} } ) = 63( {t}^{ \frac{3}{4}+\frac{2}{3} } ) \\ 63( {t}^{ \frac{9}{12} + \frac{8}{12} } ) \\ 63( {t}^{ \frac{17}{12} } )Answer[tex] \large \boxed {63 {t}^{ \frac{17}{12} } }$

What is the vertex of the parabola whose equation is y = (x + 1) ^2+ 3

lora16 [44]

Answer:

The vertex is (-1, 3)

Step-by-step explanation:

The form this is in is called vertex form. We can express the equation using its base form.

y = a(x - h)^2 + k

Now we can identify the vertex as (h, k). By looking at the equation, we can see h is equal to -1 and k is equal to 3.
