Millie needs to cook a roast lamb for 1 hour and 50 minutes at 356c. How much does the roast weigh in kilo grams if the recommendation is 20 minutes for every 250 grams
Answer:
The roast weighed 1.375 kg
Step-by-step explanation:
Here, we want to know what the roast lamb will weigh in kilograms given its cooking time.
From the question, we are told that to cook 250 grams, 20 minutes is need.
So let’s make a relationship here,
Firstly let’s express 1 hour and 50 minuets in minutes, that will be 60 + 50 = 110 minutes( 1 hour is 60 minutes)
Now;
let’s have our relationship;
20 minutes = 250 grams
110 minutes = x grams
By cross multiplication;
20 * x = 250 * 110
20x = 27,500
x = 27500/20
x = 1,375 grams
But, mathematically 1000g = 1kg
So 1,375 will be 1375/1000 = 1.375 kg
what is the value of x in 30 - 3x = 15 + 12x
Answer:
[tex]x=1[/tex]
Step-by-step explanation:
So we have the equation:
[tex]30-3x=15+12x[/tex]
First, let's add 3x to both sides. The left side cancels:
[tex]30=15+15x[/tex]
Now, subtract 15 from both sides. The right cancels:
[tex]15=15x[/tex]
Divide both sides by 15:
[tex]x=1[/tex]
So, the value of x is 1.
And we're done!
Answer:
1 =x
Step-by-step explanation:
30 - 3x = 15 + 12x
Add 3x to each side
30 - 3x+3x = 15 + 12x+3x
30 = 15x +15
Subtract 15 from each side
30-15 = 15x+15-15
15 =15x
Divide each side by 15
15/15 = 15x/15
1 =x

P = 2(I + W)
Answer:
i=12p−w
Step-by-step explanation:
Step 1: Flip the equation.
2i+2w=p
Step 2: Add -2w to both sides.
2i+2w+−2w=p+−2w
2i=p−2w
Step 3: Divide both sides by 2.
2i2=p−2w2
i=12p−w
Jed is training for a marathon. Jed ran 15.6 miles away from his home. Then Jen ran 10.8 miles towards his home. Finally, Jed ran 5.3 miles away from his home. How far is Jed from his home?
Answer:
He is 10.1 miles away from his house
Step-by-step explanation:
First you translate the text into an equation using the miles he runs away from his house as positives and the miles he runs towards his house as positives.
+15.6, -10.8, +5.3
Then you put it into an equation and solve
(15.6 - 10.8) + 5.3
4.8 + 5.3

1. If Bob scored a 75 on a test with a mean of 75, what would his z-score be?
Answer:
the z score is 25
Step-by-step explanation:
since 75 needs 25 more for and 100%
The z-score of Bob if he scored 75 on a test that has a mean of 75 is: z-score = 0.
What is the Z-score?The z-score = (raw score - mean score)/standard deviation.
A z-score of 0 means the raw score is exactly average.
For a raw score of 75, where the average(mean) is 75, the z-score would definitely be 0.
Thus, Bob's z-score is 0.

A rectangle has a perimeter of 60 inches. The length of the rectangle is 3 inches less than twice the width
Answer:
width = 11, len = 19
Step-by-step explanation:
length = 2w - 3
l = length
w = width
2(length) + 2(width) = perimeter
2(2w - 3) + 2(w) = 60
6w -6 =60
w = 11
len = 2(11) - 3
The length of the rectangle is 19 inches and the width is 11 inches
The perimeter of a rectangle is given as 2(l+w)
Now
Given that the Perimeter is 60 inches
Let the width be w
So that the Length is 2w -3
Putting the values into the equation , we have
Perimeter = 2(l+w)
Perimeter =2L + 2w
Putting the values
Perimeter =2(2w -3) + 2w
Perimeter =4w -6 + 2w
60=6w-6
60+6=6w
66=6w
w =66/6 =11inches
Since the width is 11 inches,
The length will be 2w -3 = (2x11)-3=19 inches

A school choir needs to make T-shirts for its 75 members and has set aside some money in their budget to pay for them. The members of the choir decided to order from a printing company that charges $3 per shirt, plus a $50 fee for each color to be printed on the shirts. (The fee applies to the order, not to individual shirts) Write an equation that represents the relationship between the number of T-shirts ordered, the number of colors on the shirts, and the total cost of the order. If you use variables, specify what they represent (define them).
Answer:
[tex]Equation = 225 + 50y[/tex]
Step-by-step explanation:
Given
Members = 75
Cost of Shirt = $3
Color = $50 on all shirts
Required
Determine an equation to represent the scenario
Represent the members with x
Such that:
[tex]x = 75[/tex]
First, we need to determine the total cost of ordering x shirts
A shirt costs $3;
So,
[tex]x\ shirts = 3 * x[/tex]
[tex]x\ shirts = 3 x[/tex]
Next, we determine the total cost of colors
Represent each color with y
[tex]1\ color = \$50[/tex]
[tex]y\ color = \$50 * y[/tex]
[tex]y\ color = 50 y[/tex]
The required equation is calculated as thus;
[tex]Equation = x\ shirts + y\ color[/tex]
[tex]Equation = 3x + 50y[/tex]
Substitute 75 for x
[tex]Equation = 3 * 75 + 50y[/tex]
[tex]Equation = 225 + 50y[/tex]
Answer:
50 + 3(B) + 50 + 3(R) + 50 + 3(Y) would be the equation.

Plaz mark brainliest. I just need 2 more to raise my level.
Answer:
Yes unless the fraction is equal to a whole number or is an improper fraction
Step-by-step explanation:
A normal fraction like 2/4 is less than a whole number because a whole number is whole and a fraction is part of
Exceptions:
4/4 is a fraction but is also a whole number
any improper fraction ( a fraction not simplified)
5/4 it equals more than a whole number 1 1/4
So simplify the fraction and if it is equal to or more than a whole number you know, but if it is less than a whole number then you know it is less.

imagine reflecting triangle ABC across line MN. Then answer the questions about the reflected figure
Answer:
Triangle.
Step-by-step explanation:
Reflection of an figure across any line is the mirror image of the figure.
That means reflection of a figure is a rigid transformation, in which size or shape of the image doesn't change.
Therefore, when we reflect triangle ABC across the line MN shape of the reflected angle will remain same as a triangle.

Answer:
Observational
Step-by-step explanation:
Observational studies are studies that measure the outcome of events without the introduction of interventions. They are useful in the formation of a hypothesis. The experiment described above is an observational study that compares two groups so as to measure the predictors of an outcome. No intervention is introduced to influence the outcome of the research.
An experiment on the other hand is often organized as a randomized control trial where subjects are divided into groups and a placebo or control group is introduced to monitor the outcome of the study.

The commute time to work in the U.S. Has a bell shaped distribution with a population mean of 24.4 minutes and a population standard deviation of 6.5 minutes. What proportion of the population has a commute time: a) between 11.4 minutes and 37.4 minutes? (1 pt) b) less than 11.4 minutes? (1 pt) c) greater than 37.4 minutes? (1 pt) 3. Using the parameters provided in the previous question, Q2, determine the z-score that corresponds to a commute time of 15 minutes. (2 pts)
Answer:
Q1 a) 0.9545
b) 0.02275
c) 0.97725
Q2 z is approximately equal to -1.466
Step-by-step explanation:
Q1 The given information are;
The mean time to commute to work = 24.4 minutes
The standard deviation = 6.5 minutes
a) The z-score for 11.4 is given as follows;
[tex]Z=\dfrac{x-\mu }{\sigma }[/tex]
Where;
x = Observed value 11.4
μ = The mean = 24.4 minutes
σ = The standard deviation = 6.5 minutes
[tex]Z=\dfrac{11.4-24.4 }{6.5 } = -2[/tex]
The z-score for 37.4 is given as follows;
[tex]Z=\dfrac{37.4-24.4 }{6.5 } = 2[/tex]
-2 < z < 2, which gives, from the z-score table;
The probability of commute time to be between 11.4 minutes and 37.4 minutes = 0.97725 - 0.02275 = 0.9545
b) From the z-score table, the probability that the commute time to be less than 11.4 minutes = The probability at z = -2 = 0.02275
c) From the z-score table, the probability that the commute time to be greater than 37.4 minutes = The probability at z = 2 = 0.97725
Q2 The the z-score that corresponds to a commute time of 15 minutes is given as follows;
[tex]Z=\dfrac{x-\mu }{\sigma }[/tex]
[tex]Z=\dfrac{15-24.4 }{6.5 } = -\dfrac{94}{65} \approx -1.466[/tex]

What is equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S.
There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators. An equation can be formed without these as well, for example, 5 + 10 = 15.
Given equation:
8ax−5=−3
8ax= -3+5
8ax= 2
x= 2/8a
x= 1/4a
Hence, the value of x is 1/4a
