Claire is 18 years old and her mother is 40 years old.
Answer with explanation:
Let Claire's age = x years
Age of Claire's mother =(2 x +4 ) years
Sum of the ages of Claire and her mother =58 years
If we write the above statement in terms of equation , it will be
⇒ x + 2 x +4=58
⇒3 x +4=58
⇒3 x =58 -4
⇒3 x =54
Dividing both side by , 3 , we get
→x=18
Claire's age = 18 years
Age of Claire's mother =(2 x +4 )=2×18+4=36+4= 40 years
The sum of their ages is 58. The "sum of their ages" includes:
Claire's age + 2(Claire's Gage) + 4 = 58
3(Claire's age) + 4 = 58
3 x Claire's age = 58 -4 = 54
Claire's age= 54/3 = 18
Claire is 18 years old.
Since Claire's mom is 4 years older than twice clears age, her age is (18 x 2) + 4 = 40
So Claire is 18 and her mother is 40
I hope this helps!
Magan went to the grocery store and purchased cans of soup and frozen dinners. Each can of soup has 350 mg of sodium and each frozen dinner has 650 mg of sodium. Magan purchased a total of 11 cans of soup and frozen dinners which collectively contain 4750 mg of sodium. Determine the number of cans of soup purchased and the number of frozen dinners purchased.
Magan bought 8 cans of soup and 3 cans of frozen dinners.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Let x represent the number of cans of soup purchased and y the number of frozen dinners purchased.
Magan purchased a total of 11 cans of soup and frozen dinners.
As per the given information, we can write the equations would be as
x + y = 11 ....(i)
Also:
350x + 650y = 4750
7x +13y =95 ....(ii)
Solving equations (i) and (ii) simultaneously gives the values are:
x = 8, and y = 3

The probability is
The required probability for 1 adult female is randomly selected, find the probability that her pulse rate is less than 83 beats per minute is 0.5948.
In statistics, what does a probability mean?
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes.Statistics is the study of events that follow a probability distribution.Let, X= The female have pulse rate
μ = 7.60 bpm , σ² = 12.5²
a) We find
P[ 1 adult female is randomly selected, her pulse rate is less than 79 bpm]
= P [ X < 79]
= P [ X - μ/ σ < 79 - μ/ σ ]
= P[ X - 76/12.5 < 79 - 76/ 12.5 ]
= P[Z < 0.24]

The mean age of 12 women in an office is 22 years old.
The mean age of 3 men in an office is 24 years old.
What is the mean age (nearest year) of all the people in the office?
The mean age (nearest year) of all the people in the office is 22.4.
How to find the mean age?Age for women
Age = 12 women × 22 years old / 12
Age = 264 /12
Age = 22
Age for men
Age = 3 men × 24 years old / 3
Age = 72/3
Age = 24
Now let find the mean age
Mean age = Sum of men and women age / Number of men and women
Mean age = 264 + 72 / 12 +3
Mean age = 336 /15
Mean age = 22.4

A. b = -4
B. b = 4
C. b = -24
D. b = 24
The value of b after solution of the expression, b-14 = -10, is 4.
According to the question,
We have the following expression:
b-14 = -10
Now, we will first add 14 on both sides of the above equation:
b = -10+14
We know that when two integers are of different signs then the smaller number is subtracted from the larger number but the sign in the result is of the larger number.
So, in this case, 14 is larger than 10 then the result will be positive.

a grocer wants to mix kenyan beans that sell for $8.25 per pound with venezuelan beans that sell for $9.50 per pound to form a 50 pound batch of beans that sells for $9.00 per pound. how many pounds of kenyan beans should go
into the blend?
Grocer will mix 20 pounds of the kenyan beans $8.25per/lb one and another 30 pounds of the venezuelan beans $9.50per/lb one.
Let's x be the kenyan beans that sell for $8.25 per pound and y be venezuelan beans that sell for $9.50 per pound.
Altogether there are 50 pounds of beans.
The algebraic equation would be x + y = 18.
At $9.00 per pound, he will make 50 * $9.00 = $ 450.0
So, how many of the x and y kinds of coffee should he use to make the $9.00 per pound mixture which will net him $450.0.
The algebraic equation would be 8.25x + 9.50y = 450
We now have two equations
x + y = 50 --(i)
8.25x + 9.50y = 450 --(ii)
Substituting x= 50 - y in the second equation gives us
8.25(50-y) + 9.50y = 450
412.5 - 8.25y + 9.50y = 450
1.25y = 450 - 412.5
1.25y = 37.5
y = 30
Substitute the value of y in equation(i)
x + y = 50
x = 50 - 30
x = 20
Hence, Grocer will mix 20 pounds of the kenyan beans $8.25per/lb one and another 30 pounds of the venezuelan beans $9.50per/lb one.

Answer:
m∠1 = 50°
Step-by-step explanation:
From inspection of the given diagram we can see that angle 1, angle 40° and a right angle are the interior angles of a right triangle.
As the interior angles of a triangle sum to 180°:
⇒ m∠1 + 40° + 90° = 180°
⇒ m∠1 + 130° = 180°
⇒ m∠1 + 130° - 130° = 180° - 130°
⇒ m∠1 = 50°
Therefore, the measure of angle 1 is 50°.

What is the probability that:
(i) the first ticket drawn is red and the second ticket drawn is blue?

The probability that a red ticket is drawn first and then the second ticket drawn is blue is 0.253.
What is the probability?Probability determines the odds that a random event would occur. The odds that the random event occurs has a probability value that lies between 0 and 1.
The more likely it is that the event would occur, the closer the probability value would be to 1. The more unlikely it is that the event would not happen, the closer the probability value would be to 0.
The probability that a red ticket is drawn first and then the second ticket drawn is blue = (number of red tickets / total number of tickets) x (number of blue tickets / total number of tickets)
Total number of tickets = number of blue tickets + number of red tickets
25 + 20 = 45

Given,
Out of 150 coins, 90 are quarters. Of the remaining coins, 40% are nickels and the rest are dimes and pennies. There are 5 dimes for every penny.
Here we need to find the number of pennies in the coins.

Here the number of Quarters are 90
Therefore, the remaining coins are calculated as,
=> 150 − 90 = 60
Here the percent of nickels is 40, then the number of nickels is
=> 60x 40/100

Round your answer to the nearest cent. Do NOT round until you calculate the final answer.
In the year 2018, the amount that Chase owes in federal income taxes is $16, 280.70
How to find the federal income taxes?In 2018, Chase earned $91, 630 which put him in the 24% tax bracket. Here, his tax is $14,089.50 plus 24% of every dollar above $82,500.
The amount that Chase made above $82, 500 is:
= 91, 630 - 82, 500
= $9, 130
The federal income tax that Chase owes is therefore:
= 14, 089.50 + (9, 130 x 24%)

Answer: $16,280.70
Step-by-step explanation:
First, find the difference between $91,630 and $82,500 to find the amount that is taxed at the 24% tax rate.
$91,630−$82,500=$9,130
Now, multiply $9,130 by 24% to find the additional amount of tax.
$9,130⋅24%=$2,191.20
Add $2,191.20 to $14,089.50 to find the total amount of federal income taxes Chase owes.
$2,191.20+$14,089.50=$16,280.70
Therefore, Chase owes $16,280.70 in federal income taxes for 2018.
