unit price would be price for each drink

since the overall price is 2.99 and there are 6 drinks

divide 2.99 by 6 for the unit price

2.99/6 = 0.498 cents per drink

Given the coordinates below, what is the midpoint of AB?<br> A(-6, -10)<br> B(2,5)

madreJ [45]

Given :

$\:$

A(-6, -10)
B( 2, 5)

$\:$

$\gray{ \frak{The \: given \: two \: \: points \: are(x_{1 },y_{1})=(−6 , -10)and(x_{ 2 },y_{2} )=( 2,5 )\:}}$

$\:$

Let's solve by using midpoint formula :

$\:$

$\bf \boxed{\color{red}\frak{Midpoint \: \: Formula : {( \: x ,\:y \: ) = }( \frak{ \frac{x_{1 } + y_{1}}{2} , \frac{x_{2 } + y_{2}}{2} )}}}$

$\:$

$\large \gray{ \frak{( \: x ,\:y \: ) = }( \frak{ \frac{ -6 + 2}{2} , \frac{ - 10 + 5}{2} )}}$

$\:$

$\: \large \gray{ \frak{( \: x ,\:y \: ) = }( \frak{ \frac{ -4}{2} , \frac{ - 5}{2} )}}$

$\:$

$\large \gray{ \frak{( \: x ,\:y \: ) = }( \frak{ \cancel\frac{ -4}{2} , \cancel\frac{ - 5}{2} )}}$

$\: \:$

$\underline{ \boxed{ \large \red{ \frak{option \: d }( \frak{ - 2, - 2.5)}}}}✓$

What value for c will make the expression a perfect square trinomial? x2 – 7x + c

ANEK [815]

Answer:

Final answer is $\frac{49}{4}$ .

Step-by-step explanation:

Given expression is $x^2-7x+c$ .

Now we need to find about what value for c will make the given expression $x^2-7x+c$ , a perfect square trinominal.

Coefficient of middle term that contains x, in $x^2-7x+c$ -7.

Take half of that so we get $-\frac{7}{2}$ .

Then take square of the half value.

We get $\left(-\frac{7}{2}\right)^2=\frac{49}{4}$ .

We add the square value to make perfect square trinomial.

Hence final answer is $\frac{49}{4}$ .

The length of one leg of a right triangle is 7 cm more than that of the other leg. The length of the hypotenuse is 3 cm more tha

Lady bird [3.3K]

Answer:

The lengths are 5, 12, and 13.

Step-by-step explanation:

Let x represent the shorter leg of the triangle. Since the other leg is 7 cm more, the longer leg is x+7. Since the length of the hypotenuse is 3 cm more than double that of the shorter leg, the hypotenuse is 2x+3.

The Pythagorean Theorem may be used to find the lengths.

$a^{2}$ + $b^{2}$ = $c^{2}$ a, b are the short and long lengths and c is the hypotenuse

→ $x^{2} + (x+7)^{2} = (2x+3)^{2}$

→ $x^{2} + x^{2} + 14x + 49 = 4x^{2} + 12x + 9$

→ $2x^{2} + 14x + 49 = 4x^{2} + 12x + 9$

→ $2x^{2} - 2x - 40 = 0$

→ $x^{2} - x - 20 = 0$

→ $(x-5)(x+4) = 0$

→ $x = 5$ (The length cannot be negative)

The shorter leg, x, is 5 cm. Since the longer leg is x+7, it is 12 cm. Since the length of the hypotenuse is 2x+3, the hypotenuse is 13 cm.

shtirl [24]

Answer:

Rational

please put me as brainliest

Step-by-step explanation:

Here 3 is recurring , so from statement 1) 0.3333 or 1/3 is a rational number. And also 0.3333 is non-terminating as the decimal is not ending or the remainder for 1/3 is not zero
