Step-by-step explanation:
To find out how much Tyrell ate, you multiply 6 times two (which is 12), then to find out how much Lucy ate, you have to divide 2 and 6 (Which is 3) . Now you add up how many they ate in all.. 6 (Katy) plus 12 (Tyrell) and that equals 18, then you add 3 (Lucy), which comes to a total of 21

Find the value of x. The diagram is not to scale. Explain your reasoning.
Answer:
x = 24
Step-by-step explanation:
Since SR = ST then Δ RST is isosceles, thus the base angles are congruent.
∠ SRT = ∠ STR = 4x - 60
∠ STR and ∠ STU are adjacent and supplementary, thus
∠ STR + ∠ STU = 180, substitute values
4x - 60 + 6x = 180, that is
10x - 60 = 180 ( add 60 to both sides )
10x = 240 ( divide both sides by 10 )
x = 24

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).
Consider the equation below.
–2(bx - 5) = 16
The value of xin terms of b is
The value of x when bis 3 is
Answer:
If b is 3, x=-1
Step-by-step explanation:
-2(3x-5)=16
use distributive property
-6x+10=16
take 10 away from both sides
-6x=6
divide both sides by -6
x=-1
The value of x in terms of b is given by equation x = -3/b
The value of x when b = 3 , is x = -1
What is an 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.
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 data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
The given equation is:
-2(bx - 5) = 16
To solve for x in terms of b, we need to isolate x on one side of the equation. We can start by distributing the -2 on the left-hand side:
-2bx + 10 = 16
Next, we can subtract 10 from both sides:
-2bx = 6
Finally, we can divide both sides by -2b to solve for x:
x = -3/b
So the value of x in terms of b is -3/b.
To find the value of x when b is 3, we can substitute b = 3 into the equation we just found:
x = -3/b = -3/3 = -1
Hence , the equation is solved and when b is 3, the value of x is -1.

The formula for the circumference C of a circle with diameter d is C = xd. Write an expression to represent the circumference of the following circle
The circumference of a circle is calculated based on its diameter using the formula C = πd. Replace 'd' with the value of the circle's diameter to obtain an expression representing the circumference.
Explanation:The formula for the circumference C of a circle with a diameter d is given by C = πd, where π (Pi) is approximately 3.14. To write an expression to represent the circumference of a specific circle, simply replace the term 'd' with the actual diameter of the circle. For example, if the diameter of the circle is 10 units, then the expression for the circumference would be C = π * 10 or C = 3.14 * 10, hence the circumference C of the circle would be about 31.4 units.

How do you set up this equation ?
Given:
Quadrilateral PQRS is a rhombus.
To find:
The value of y.
Solution:
In the rhombus PQRS,
PS = 10y and SR = y + 45
Property of rhombus:
All sides are congruent.
⇒ PS = SR
⇒ 10y = y + 45
Subtract y from both sides.
⇒ 10y - y = y + 45 - y
⇒ 9y = 45
Divide by 9 on both sides.
[tex]$\Rightarrow \frac{9y}{9} =\frac{45}{9}[/tex]
⇒ y = 5
The value of y is 5.

1. What If? If Alex had saved $333.34 a month for 3 months, how
much money would he have? If he had used his savings instead
of his credit card, how much less would his purchases have cost him?
2. How much less did Barry's loan, at an interest rate of 9%, cost than
Alex's loan at 21%?
Alex would have saved $1,000.02 over 3 months. The cost of purchases would have been less if he used his savings instead of a credit card because of no interest rates applied. Barry's loan is $120 less expensive than Alex's loan
Explanation:If Alex had saved $333.34 a month for 3 months, he would have saved $333.34 x 3 = $1,000.02. As for the cost of purchases using savings instead of a credit card, we can't directly answer that without knowing the associated credit card interest rate & the time duration. In general, using a credit card would have cost more due to the interest applied to the unpaid balance.
For the second part of your question related to loans, let's assume both Alex and Barry took out loans of $1,000 each for one year. Alex's loan, with an interest rate of 21%, would cost him $1000 x 21/100 = $210 in interest. Barry's loan, at an interest rate of 9%, would cost him $1000 x 9/100 = $90 in interest. Therefore, Barry's loan costs $210 - $90 = $120 less than Alex's loan.

Final answer:
To convert 56/15 to a decimal and round to the nearest tenth, you divide 56 by 15 to get 3.7333 and then round it down to 3.7 since the hundredths place is less than 5.
Explanation:
The question is asking to convert the fraction 56/15 to a decimal and round it to the nearest tenth. To convert a fraction to a decimal, you need to divide the numerator by the denominator. In this case, divide 56 by 15. The decimal form of 56/15 is approximately 3.7333. When rounding this number to the nearest tenth, we look at the hundredths place, which is a 3. Since it's less than 5, we do not round up. Therefore, the decimal rounded to the nearest tenth is 3.7.
The diagram below shows triangle MNR with ray NM. Triangle M N R. Angle N is 97 degrees. Side N M extends to form an exterior angle of M with a measure of 115 degrees. What is the measure of Angle M R N? 3° 5° 18° 28°
Answer:
18 degrees.
Step-by-step explanation:
115-97=18
The calculated measure of the angle MRN is 18 degrees
Calculating the measure of Angle MRN?From the question, we have the following parameters that can be used in our computation:
Triangle = MNR
Angle N = 97 degrees
From the attached figure
Segment NM is an extension from the exterior angle of M
By the sum of opposite interior angles of triangle, we have
MRN + ∠N = 115 degrees
This means that
MRN + 97 = 115 degrees
Subtract 97 from both sides
MRN = 18 degrees
Hence, the measure of the angle MRN is 18 degrees

Penny drives a truck. The function p = 20h + 75 represents her daily pay, in dollars, for working h hours. She travels 60 miles each hour. She also receives $0.10 for each bonus mile she drives. The function b = 60h × (0.10) represents the amount she earns for her bonus. Which function represents Penny's earnings, P, for driving h hours?
Answer:
Penny's earning for driving h hours is represented by the function
P = 26h + 75
Step-by-step explanation:
- The function p = 20h + 75 represents her daily pay
- The function b = 60h × (0.10) represents the amount she earns for her bonus.
Penny's earnings is the addition of her daily pay and bonus.
It is represented by the function P.
P = (20h + 75) + 60h × 0.10
Simplifying this, we have
P = 20h + 75 + 6h
= 26h + 75

Which statement best describes the association between variable X and variable Y?
moderate positive association
perfect positive association
moderate negative association
perfect negative association
The correct answer is the fourth option.
Given is a scatter graph with points marked on the graph. The x axis shows the dependent variable and y axis the independent variable
From the graph we see that there seems to be a linear relationship but not fully perfect. Because so many points deviate from the line we can only say that there is a moderate association.
Whenever x increases y increases also the linear regression line of fit has a positive scope.
Hence there is a positive association between variable x and variable Y.

There are 8 marbles in a jar. One of the marbles is clear. What is the decimal expansion of 1/8? please help me
Answer:
Step-by-step explanation: 1/8 = .125
move two decimals to right = 12.5
The decimal expansion of 1/8 is 0.125, which is also the probability of drawing a clear marble from a jar of eight marbles, if only one of those marbles is clear.
Explanation:The question asks for the decimal expansion of 1/8. To determine the decimal expansion of the fraction, you simply divide the numerator (the top number, which in this case is 1) by the denominator (the bottom number, which in this case is 8). When performed, 1 divided by 8 results in the decimal 0.125. This concept is similar to calculating probabilities in which the total number of outcomes is divided by the desired outcome. For example, in the case of the marbles in a jar, if one is clear and there are eight total, the probability of drawing a clear marble is also 1/8 or 0.125.
