Answer:
$27.83
Step-by-step explanation:
15.88+5(.55)+12(.85)=28.83
Answer:
Ann spent $28.83.
Why?
We can find the answer by just multiplying the prices of cookies and doughnuts by their amounts, and adding the total prices together. 0.55 x 5 = $2.75, 0.85 x 12 = $10.20. 2.75 + 10.20 + 15.88 = 28.83. Therefore, Ann spent $28.83.

Jason has a starting salary of 9.25 per hour .Jason’s manager informs him that if he meets his self quota each month he can expect annual pay rate increase of 0.90 write an equation representing the relationship between the years on the job y and pay per hour p
Answer:
Assuming the "pay increase" is $/hr: p = 9.25 + 0.90y
Step-by-step explanation:
p = 9.25 + 0.90y : The 9.25 is for year (y)=0[the starting hourly wage]. 0.90 is added each year, starting with y=1. Each addirtional year add one more 0.90 to his starting wage.

39% of the boys play a sport, who plays more sports?
Answer:
The boys play more sports.
Step-by-step explanation:

In the given figure, m ǁ n, then the value of y is:
(a) 70°
(b) 35°
(c) 60°
(d) 40°
Answer:
(b) 35°Step-by-step explanation:
x + 60° = 180° ( interior angles )
[tex]x + {60}^{o} = {180}^{o} \\ x = {180}^{o} - {60}^{o} \\ x = {120}^{o} \\ [/tex]
x = z ( opposite angles )
z = 120°
y + 25° + 120° = 180°
(The sum of all interior angles of any triangle is equal to 180°)
[tex]y + {25}^{o} + {120}^{o} = {180}^{o} \\ y + {145}^{o} = {180}^{o} \\ y = {180}^{o} - {145}^{o} \\ y = {35}^{o} \\ [/tex]
The value of y in the given figure is (b) 35°
Since m||n, hence:
a + 60 = 180 (sum of consecutive interior angles formed by two parallel lines are supplementary)
a + 60 = 180
a = 120°
a = b (vertical opposite angles are congruent to each other)
120 = b
b = 120°
y + 25 + b = 180 (sum of angles in a triangle)
y + 25 + 120 = 180
y + 145 = 180
y = 35°
Hence the value of y is (b) 35°

3 friends went to lunch and total was $38.49. how much would it have cost 7 friends
Answer:
89.81
Step-by-step explanation:
divide 38.49 by 3 and you get 12.83
then multiply 12.83 by 7
Answer:
Step-by-step explanation:
Cost of lunch for 3 persons = $ 38.49
Cost of lunch for 1 person = 38.49 ÷ 3 = $ 12.83
Cost of lunch for 7 persons = 12.83 * 7 = $ 89.81

Step-by-step explanation:
fatima claims that the distribution of u is uniform with a median of 0.4 field goal percentage. is fatima’s claim supported by the table?
Fatima's claim is not supported by the table because, the distribution is skewed right, with a median of 0.4 field goal advantage.
From the table, the median position is calculated as:
[tex]\mathbf{Median = \frac{1}{5} th}[/tex]
[tex]\mathbf{Median = 0.2\ nd }[/tex]
The 0.2nd data falls in the 0.4 field goal category.
So, the median element is:
[tex]\mathbf{Median = 0.4}[/tex]
However, the distribution of the table are concentrated on the left.
This means that, the distribution is not uniform, instead it is skewed right.
A uniform distribution has a skewness of 0.
Hence, Fatima's claim is not supported by the table

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
given:
0.4x = 2.8
Now, solving for x
Dividing both side by 0.4 we get
0.4x/ 0.4 = 2.8 / 0.4
x = 28/4
x= 7

if f(x)=2x-3 find f(7)
Answer:
f(7) = 11
Step-by-step explanation:
Given the linear function, f(x) = 2x - 3:
In order to find the value of f(7), simply substitute the value of the input, x = 7 into the function:
f(x) = 2x - 3
f(7) = 2(7) - 3
f(7) = 14 - 3
f(7) = 11
Therefore, the value of f(x) when x = 7 is:
