Answer:
6 days
Step-by-step explanation:
Given
[tex]Rate = -1\frac{1}{2}^\circ F[/tex] -- Negative because it decreases
[tex]Final\ Temperature = -9^\circ F[/tex] -- Negative because it still decreases
Required
Determine the number of days
Let the number of days be d.
So:
[tex]Rate * d = Final[/tex]
[tex]-1\frac{1}{2} * d = -9[/tex]
[tex]1\frac{1}{2} * d = 9[/tex]
Convert to improper fraction
[tex]\frac{3}{2} * d = 9[/tex]
Make d the subject
[tex]d = \frac{9 * 2}{3}[/tex]
[tex]d = 3 * 2\\\\d = 6[/tex]

Answer:
29.3
Step-by-step explanation:
to find average you find the sum of all the minutes she practiced and divide it by the total amount of day she practiced.
first we have to find the sum of the minutes she practiced:
20+30+40+38+25+22+39+22+26+31
this equation is equal to 293 minutes she practiced in total. Now we have to divide this by the total amount of days she practiced whice according to the data is 10! So:
293/10 =29.3

Four wholesalers are having specials on chicken this week.
A table is shown. The table has three columns and four rows. The first column is labeled Wholesaler. The second column is labeled Pounds of Chicken. The third column is labeled Cost. Wholesaler A, ten pounds of chicken, forty dollars. Wholesaler B, fifteen pounds of chicken, forty-five dollars. Wholesaler C, twenty pounds of chicken, fifty dollars. Wholesaler D, twenty-five pounds of chicken, eighty dollars.
Which wholesaler has the best price on chicken?
a
wholesaler A
b
wholesaler B
c
wholesaler C
d
wholesaler D
Answer:
Wholesaler A.
Step-by-step explanation:
First, put the pounds and dollars into fraction form. Then simplify those fractions. Finally, convert the fractions into decimals and compare the unit prices for each wholesaler. Whichever one is the lowest has the best price.
find the direction angel of this vector <-5, 9>
Answer:
θ = -60.94°
Step-by-step explanation:
The given vector is:
v = -5i+9j
We need to find the angle of this vector.
The angle of this vector form is given by :
[tex]\tan\theta=\dfrac{y}{x}\\\\\tan\theta=\dfrac{9}{-5}\\\\\tan\theta=-1.8\\\\\theta=\tan^{-1}(-1.8)\\\\=-60.94^{\circ}[/tex]
So, the angle of this vector is -60.94°.

Step-by-step explanation:
plese help with both of these
Answer:
Step-by-step explanation:
Explicit formula of a G.P. is given by,
[tex]a_n=a(r)^{n-1}[/tex]
Here, [tex]a_n[/tex] = nth term
a = First term
n = number of term
r = common ratio
Given sequence is 3, 6, 12, .......
a = 3
r = [tex]\frac{6}{3}[/tex] = 2
Therefore, explicit formula will be,
[tex]a_n=3(2)^{n-1}[/tex]
Option (3) is the answer.
Parent function → f(x) = 3ˣ
Transformed function → g(x) = [tex]3^{x+5}[/tex]
Since, g(x) = f(x + 5)
Therefore, function 'f' has been shifted 5 units left.
Option (1) is the answer.
5x + 13 + (2y-7)i = -2 + i please please help
Find the equation of the line given the two points below
A(−3,−2) B(6,−8)
Answer:
y = -2/3x - 4
Step-by-step explanation:
Formula: y = mx + b
m (slope)
b (y-intercept)
Slope Formula: y2 - y1 ÷ x2 - x1
Substitute: -8-(-2) = -8+2 = -6
6-(-3) = 6+3 = 9
-6/9 (funny, I know)
Simplify --> -2/3
slope = -2/3
Substitute for the y-intercept --> to do this, we plug in a coordinate pair
-8 = -2/3(6) + b
-8 = -4 + b => add 4 to both sides
b = -4, and thus, our y-intercept is -4
Plug our values into the formula: y = mx + b
y = -2/3x + (-4)
simplify to get our final equation
y = -2/3x - 4

Write the following in slope intercept form. 3x+5=2y
Step-by-step explanation:
Given
3x + 5 = 2y
Writing in slope intercept form
y = (3x + 5) / 2
y = 3/2 x + 5/2
Hope it will help :)
3x+5=2y
here's some answer's
if it is from exact then it is : y= 15/2
if it is from decimal then it is : y= 7.5
if it is from mixed number then it is : y 7 1/7
Nancy lives in a state where sales tax is 9%. This means you can find the total cost of an item, including tax, by using the expression c + 0.09c, where c is the pre-tax price of the item.
Use the expression to find the total cost of an item that has a pre-tax price of $84.00.
9514 1404 393
Answer:
$91.56
Step-by-step explanation:
We can simplify Nancy's cost expression to ...
c +0.09c = c(1 +0.09) = 1.09c
The the total cost of the item of interest is ...
(1.09)($84) = $91.56

Answer:
[tex]\text{D. The terms may be combined.}[/tex]
Step-by-step explanation:
Recall that [tex]\sqrt{a\cdot b}=\sqrt{a}\cdot\sqrt{b}[/tex]. Using this, we can simplify and combine the two terms:
[tex]6\sqrt{32}-12\sqrt{72},\\=6\cdot \sqrt{4}\cdot \sqrt{8}-12\cdot \sqrt{9}\cdot \sqrt{8},\\=6\cdot 2\cdot \sqrt{8}-12\cdot 3\cdot \sqrt{8},\\=12\sqrt{8}-36\sqrt{8},\\=-24\sqrt{8}=-24\cdot\sqrt{4}\cdot\sqrt{2}=\boxed{-48\sqrt{2}}[/tex]. Therefore, the terms may be combined.
