£50 is divided between Krutika, Natasha & Richard so that Krutika gets twice as much as Natasha, and Natasha gets three times as much as Richard. How much does Krutika get?
Answer:
£30
Step-by-step explanation:
→ Model the situation in terms of x
Richard = x, Natasha = 3x and Krutika = 6x
→ Now put the values into ratio form
6x : 3x : x = 50
→ Collect the x terms
10x = 50
→ Divide both sides by 10 to isolate
x = 5
→ Substitute x = 5 into Krutika
6 × 5 = 30
Answer:
£30
Step-by-step explanation:
Let's break down the information given to help us find how much Krutika gets.
"Natasha gets three times as much as Richard" - We can express the value that Natasha gets as [tex]3r[/tex] in terms of what Richard gets.
"Krutika gets twice as much as Natasha" - We can express this as [tex]2(3r)[/tex] which equals [tex]6r[/tex].
We know that the total money is £50, so we can write the equation:
[tex]r+3r+6r=50[/tex]
[tex]10r = 50[/tex]
[tex]r=5[/tex]
∴ Richard gets £5.
Since the money Krutika gets can be expressed as [tex]6r[/tex]:
[tex]6(5) = 30[/tex]
∴ Krutika gets £30.
Hope this helps :)

25
will he have in 1 vear?
Answer:
Step-by-step explanation:
The amount of money Robert has after 1 year is; $2495.
How to solve Algebra Word Problems?We are told that Robert came up with the following expression 45w + 155.
where w is the number of weeks that he has been saving.
The equation above represents the amount he will have in his bank account.
Now, 1 year has 52 weeks. Thus, the amount he would have saved in 52 weeks is;
45(52) + 155 = $2495
Thus, we conclude that the amount of money Robert has after 1 year is $2495.

How many x-intercepts would the function shown below have? F(x)=-5(x^2-7)(x+6)^2(x+1)(4x+1)
Answer:
5
Step-by-step explanation:
plug this ecuation into desmos graphing calculator(it's a website). Then see how many times the graph crosses the x-axis.
To find the zeroes:
0 of a function means for what value(s) of x will the f(x) or y equal zero(0). To find the zeroes of this function, just see what numbers will make f(x) = 0. Since this equation is already factored, our job is much easier. Focus on small parts of the equation and don't get ovewhelmed by how long it its. For you problem, start by -5(x^2-7). what x will make -5(x^2-7) = 0? As long as (x^2-7) = 0, the whole equation will equal zero since any number times 0 is 0. (x^2-7)=0, move -7 to the right, x^2=7, get squre root of both sides, you will have x=plus or minus[tex]\sqrt{7}[/tex]. This is one of the zeroes. There are many more in this equation since we have more than one x-intercepts. Now using thsi tactic, you can solve for the rest of the zeroes.
there is a calculator called symbolab, It's also a website and it can calculate whatever you need.
The number of x-intercepts is five would be the given function.
What is x-Intercept?The x-intercept is defined as an intercept that is located at the x-axis of the plane, is the location or coordinate from where the line crosses,
The function is given in the question
F(x) = -5(x²-7)(x+6)²(x+1)(4x+1)
We have to determine the number of x-intercepts that would the function.
F(x) = -5(x²-7)(x+6)²(x+1)(4x+1)
The x-intercept occurs at a point where F(x) = 0
0 = -5(x²-7)(x+6)²(x+1)(4x+1)
-5(x²-7)(x+6)²(x+1)(4x+1) = 0
Here (x²-7) = 0, and (x+6)² = 0, (x+1) = 0, and (4x+1) = 0
x² = 7 , and (x+6) = 0, x = -1 , and 4x = -1
x = ±7 and x = -6 , x = -1 , and x = -1/4
x = 7, -7 and x = -6 , x = -1 , and x = -1/4
Therefore, the number of x-intercepts is five would be the given function.

Un chef tiene 24 patatas. Si necesita 178 patatas para la cena de Navidad. ¿Cuántas patatas va a necesitar ahora? Luego le informan de que necesita 89 chuletones asados con mantequilla. Si cada chuletón cuesta 3 € y la unidad de caja de mantequilla 50 cts y necesita una caja para cada chuletón. ¿Cuánto se va a gastar en total?
Answer:
El chef necesitará 154 patatas.
El gasto total será 311.5 €
Step-by-step explanation:
Un chef tiene 24 patatas. Si necesita 178 patatas para la cena de Navidad. ¿Cuántas patatas va a necesitar ahora?
Para calcular la cantidad de patatas que el chef necesita debes hacer la diferencia entre la cantidad de patatas requeridas para la cena de Navidad y la cantidad de patatas que el chef ya tiene. Esto es:
178 -24= 154 patatas
El chef necesitará 154 patatas.
Luego le informan de que necesita 89 chuletones asados con mantequilla. Si cada chuletón cuesta 3 € y la unidad de caja de mantequilla 50 cts y necesita una caja para cada chuletón. ¿Cuánto se va a gastar en total?
Ahora el chef necesita 89 chuletones asados con mantequilla, y necesita una caja de mantequilla para cada chuletón. Por lo que necesita 89 chuletones y 89 cajas de mantequilla.
Si cada chuletón cuesta 3 € y la unidad de caja de mantequilla 50 cts (equivalentes a 0.5 €), entonces el gasto total será calculado como:
89 chuletones* 3 € + 89 cajas de mantequilla* 0.5 €= 311.5 €
El gasto total será 311.5 €

3. D is the midpoint of segment AC (statement 2)
Definition of midpoint (reason 3)
SSS postulate (reason 5)
4. b. AC ≅ DC.
5. c. ∠ABC ≅ DBC.
What is the Definition of a Midpoint?The midpoint of a segment is where the segment is divided into two equal parts.
Thus, in question one, the statement that matches the reason in step 2 is: d. QS ≅ ST.
What is the Definition of Perpendicular Lines?Two lines that are perpendicular to each other will form right angle where they intersect each other.
Therefore, in question 2, the statement for step 2 reason is: a. ∠A and ∠D are right angles.
For question 3, the statement for the reason in step 2 is D is the midpoint of segment AC; the reason in step 3 why AD ≅ CD is: definition of midpoint, while both triangles are congruent to each other based on SSS postulate.
In question 4, since BC bisects segment AD, therefore, the statement for reason 2 is: b. AC ≅ DC.
In question 5, since BC bisects angle ABD, therefore, the statement for reason 2 is: c. ∠ABC ≅ DBC.
In summary, applying the definition of midpoint among other definitions, the missing statements or reasons in the two-column proofs are:
1. d. QS ≅ ST.
2. a. ∠A and ∠D are right angles.
3. D is the midpoint of segment AC (statement 2)

What is the slope between points T (9, -3) and U (-4, 1)?
Answer:
The slope between points T (9, -3) and U (-4, 1) is [tex]\mathbf{-\frac{4}{13}}[/tex]
Step-by-step explanation:
We need to find the slope between points T (9, -3) and U (-4, 1)
The formula used to find slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\[/tex]
We are given: [tex]x_1=9,y_1=-3, x_2=-4, y_2=1[/tex]
Putting values and finding slope:
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\\\Slope=\frac{1-(-3)}{-4-9} \\Slope=\frac{1+3}{-4-9} \\Slope=\frac{4}{-13}\\Slope=-\frac{4}{13}[/tex]
So, slope between points T (9, -3) and U (-4, 1) is [tex]\mathbf{-\frac{4}{13}}[/tex]

A student claims that more than 55% of the mothers with school-age children worked outside the home. The student finds that a sample of 150 mothers from Bronx New York revealed that 96 were working outside the home. At a significance level of = 0.05, is the student correct?
Answer:
There is sufficient evidence that the students claim is correct.
Step-by-step explanation:
From the information given:
The population proportion P = 55% = 0.55
The sample size n = 150
The sample mean x = 96
The sampling proportion from the sample mean [tex]\hat p = \dfrac{x}{n}[/tex]
[tex]\hat p = \dfrac{96}{150}[/tex]
[tex]\hat p =0.64\\[/tex]
The null and alternative hypothesis is:
[tex]H_o : p = 0.55 \\ \\ H_1 : p > 0.55[/tex]
The test statistics can be computed as follows:
[tex]Z = \dfrac{\hat p - p}{\sqrt{\dfrac{p(1-p)}{n}}}[/tex]
[tex]Z = \dfrac{0.64 - 0.55}{\sqrt{\dfrac{0.55(1-0.55)}{150}}}[/tex]
[tex]Z = \dfrac{0.09}{\sqrt{\dfrac{0.2475}{150}}}[/tex]
[tex]Z = \dfrac{0.09}{\sqrt{0.00165}}[/tex]
Z = 2.22
The P - value = P ( Z > 2.22)
= 1 - P( Z < 2.22)
= 1 - 0.98679
= 0.01321
Since P-value is less than the level of significance ∝ = 0.05
We reject the null hypothesis [tex]H_o[/tex]
Conclusion: There is sufficient evidence that the students claim is correct.

How many more students enrolled in drivers education in 2005 than in 1995? Pls give a full sentence and explain how you did it.
Answer:
In total 177 more students enrolled this year.
Step-by-step explanation:
First get the sum of the students who enrolled in 1995, then the sum of 2005 and then subtract the sums.
Answer:
177 more students
Step-by-step explanation:
1995 had 65 students enrolled
females - 23 males - 42
23 + 42 = 65
2005 had 242 students enrolled
113 + 129 = 242
now to get how many more, you'll want to subtract
242 - 65 = 177
we know this is correct by adding 65 to 177
177 + 65 = 242
either way our answers will be the same
