Answer:
turkey: $3.50
ham: $3
Step-by-step explanation:
Use system of equations:
turkey-x ham-y
5x+7y=38.5
4x+6y=32
multiply by 4 on equation 1 and multiply by 5 on equation 2
20x+28y=154
20x+30y=160
-2y=-6
y=3 ham is $3
5x+7(3)=38.5
5x=38.5-21
5x=17.5
x=3.5 turkey is $3.50

Describe the solution of g(x) shown in the graph. parabola opening down passing through 0 comma 2, negative 1.5 comma 4.25, and negative 3.5 comma 0 All real solutions All negative solutions All whole number solutions All solutions that lie on g(x)
Answer:
(A)All real solutions
Step-by-step explanation:
Given the function g(x) shown on the graph
One of the points of the parabola is (-3.5, 0).
The point x=-3.5 is one of the solution of the parabola since it intersects the x-axis at that point.
The other point of intersection is on the positive side between 0 and 1.
Therefore, g(x) has two solutions: One negative real number and one positive real number.
Therefore, g(x) has all real solutions.
The correct option is A.
Answer:
All solutions that lie on g(x)

What is the measure of angle Q to the nearest whole degree?
43°
49°
53°
58°
Answer:
m∠Q ≈ 53°
Step-by-step explanation:
To find the measure of ∠Q, the law of cosines will need to be used. Lowercase letters represent the side lengths, while upper case letters represent angles.
In this situation, 'A' will be ∠Q. Therefore:
17² = 18² + 20² -2(18)(20)cosQ
Simplify:
289 = 324 + 400 -2(360)cosQ
Continue simplifying down:
-435 = -720cosQ
Divide both sides by '-720':
0.604 = cosQ
[tex]cos^{-1}Q = 0.604[/tex]
m∠Q ≈ 52.83 or 53° rounded to the nearest whole degree.
Based on the calculations, the measure of angle Q to the nearest whole degree is equal to 53°.
How to calculate the measure of angle Q?Based on the triangle attached in the image above, we can deduce the following parameters:
Side QM = 18 units.Side MN = 17 units.Side QN = 20 units.In this scenario, we would apply the cosine trigonometry function to determine the measure of angle Q:
MN² = QM² + QN² - 2(QM)(QN)cosθ
17² = 18² + 20² - 2(18)(20)cosθ
289 = 324 + 400 - 720cosθ
720cosθ = 724 - 289
720cosθ = 435
θ = cos⁻¹(435/720)
θ = cos⁻¹0.6042
θ = 52.8 ≈ 53°.

a wedding ring costs £13000. Work out the price after a 11% increase
Answer:
14430 pounds
Step-by-step explanation:
Given that:
cost of ring: 13000
percentage increase: 11%
So, to find the new cost, we have to find the increase cost, in pounds:
11 / 100 times 13000 = 1430 pounds.
NOW to calculate the new cost, we add the increase cost to the original:
13000 + 1430 = 14430

An urn contains 7 pink and 5 black balls. Four balls are randomly drawn from the urn in succession, with replacement. That is, after each draw, the selected ball is returned to the urn. What is the probability that all 4 balls drawn from the urn are pink? Round your answer to three decimal places.
Answer:
.116
Step-by-step explanation:
7 pink and 5 black balls. = 12 balls
P( pink) = pink balls/ total = 7/12
replace
P( pink) = pink balls/ total = 7/12
so this is true for each case
P( pink, pink, pink, pink) = 7/12*7/12*7/12*7/12 = 2401/20736
=.115788966
To 3 decimal places

The theoretical probability of rolling an even number is one-half.
Option B is the correct answer.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
To find the theoretical probability of rolling an even number, we need to determine how many of the 6 possible outcomes are even.
In this case, we have 3 even outcomes: 2, 4, and 6.
Therefore, the probability of rolling an even number on a fair die is:
P(even) = number of even outcomes / total number of outcomes
P(even) = 3 / 6
P(even) = 1/2
Thus,
The theoretical probability of rolling an even number is one-half.

Please answer correctly !!!!!!! Will mark brainliest !!!!!!!!!!!
Answer & Step-by-step explanation:
In the problem, we are given an equation. h(t) = -20 + 11t
In the equation, t represents an unknown value. So, if we are given a number that is in the replacement of t, then we can plug that number in to where t is at.
t = 11
h(11) = -20 + 11(11)
h(11) = -20 + 121
h(11) = 101
So, h(11) is equal to 101
Answer:
101
Step-by-step explanation:
h(t)= -20+11t
h(11)= -20+11(11)
h(11)= -20+121
h(11) = 101

1. Kane earns an annual salary of $42,500.
He is paid twice a month with paychecks being
of equal amounts. If Medicare taxes
represent 1% of his income, then how much
will Kane bring home after Medicare taxes?
Answer:
$1753.13
Step-by-step explanation:
Kane's Annual Salary = $42,500
Gross Pay = $42,500
Net Pay = Gross Pay - 1% of Gross Pay
=42500 - (0.01 X 42500)
=$42,075
Since he is paid twice a month with paychecks being of equal amounts.
Number of Payments in a Year =12 X 2= 24
Therefore, Kane's Take Home pay after Medicare taxes
[tex]= \$42075 \div 24\\=\$1753.13$ (to the nearest cent)[/tex]

Answer:
F is greater than 25
F is positive
Step-by-step explanation:
You know that F must be positive, since a number is subtracted from it and then another number is multiplied by that difference. Since a positive number multiplied by a negative number is negative, F must be positive.
You also know that F is greater than 25, because a number is subtracted from it and it is multiplied by a fraction between 0 and 1, meaning that that difference is further reduced.

Mrs. Quotient asked her students to simplify each of the expressions below. Which of the numbered choices represents the expressions which simplified to the same result? A 126/2 B 23 × 3 C 3 × 21
When simplifying an algebraic expression, the following steps are needed to be taken.
Firstly, remove parenthesis by multiplying the constant with the term in the parenthesis or remove parenthesis using exponent rules for parenthesis in exponent form.
Secondly Combine terms by adding coefficients of terms with the same order and lastly sum all constant.
A) 126/2
Applying the division rule give:
126/2 = 63
B) 23 × 3
Applying multiplication rule gives:

HOW DO I FIND THE AREA OF DEF?
Answer:
169.7
Step-by-step explanation:
first lets find the other side of the small triangle
cos(30 degrees)=(7*sqrt (3))/x
x*cos(30 degrees)=7*sqrt (3)
x=(7*sqrt (3))/cos(30 degrees)
x=14
14/14=1
so proportion is 1/1
thus the bottom the outer part of the triangle is also 7*sqrt(3)
now, for the area
lets find the 2 side length of the triangle we need
DE: 14+14=28
DF: 7*sqrt(3)+7*sqrt(3)=14*sqrt(3)
let's find EF,
sin(30 degrees)=x/28
x/28=sin( 30 degrees)
x=28*sin( 30 degrees)
x=14
A=(14*sqrt(3))*14*0.5
A=(14*sqrt(3))*7
A= around 169.7
Answer:
≈169.7
Step-by-step explanation:
cos30 = (7[tex]\sqrt{3}[/tex])/x
x= (7[tex]\sqrt{3}[/tex])/cos30 = 14
h = 14+14 = 28
sin30 = EF/28
EF = sin30 * 28 = 14
tan30 = 14/DF
DF = 14/tan30 ≈ 24.248
Area = 24.248*14/2 ≈ 169.74 ≈ 169.7
