Answer:

they have 214 grams of cheese together

Answer:

214g

Step-by-step explanation:

Sara has 84 grams of cheese.

Olivia has 130 grams of cheese.

Total amount of cheese = Sara's cheese + Olivia's cheese

Total amount of cheese = 84 + 130

214 = 84 + 130

Answer:

4 g after 30 seconds.

Step-by-step explanation:

After 10 seconds 32 * 1/2  = 16 g are present.

After 20 seconds 32 * (1/2)^2 = 8 g are present

After 30 seconds 32 * (1/2)^3 = 4 g are present.

Answer:

The measure of side BD is 8.6  and The measure of side CE is 8.4  

Step-by-step explanation:

Given as :

The Triangle is ABC with side AB , BC , CA

And The points E  and D  is on the side AB and AC

So, AED is a Triangle

And Δ AED [tex]\sim[/tex] Δ ABC

The measure of side AD = 6.9

The measure of side AE = 7.2

The measure of side ED = 5.2

The measure of side BC = 10.2

Let The The measure of side EB = x

And The measure of side DC = y

So, From similarity property

[tex]\dfrac{AB}{AE}[/tex] = [tex]\dfrac{AC}{AD}[/tex] = [tex]\dfrac{BC}{ED}[/tex]

Or,  [tex]\dfrac{AB}{AE}[/tex] = [tex]\dfrac{BC}{ED}[/tex]

So, [tex]\dfrac{7.2 + x}{7.2}[/tex] = [tex]\dfrac{10.2}{5.2}[/tex]

Or, 5.2 × ( 7.2 + x ) = 10.2 × 7.2

Or, 37.44 + 5.2 x = 73.44

Or, 73.44 - 37.44 = 5.2 x

∴ x = [tex]\frac{36}{5.2}[/tex]

I.e x = 6.9

Now in Δ BED

BE² + ED² = BD²

Or, 6.9² + 5.2² = BD²

Or, BD² = 74.65

∴  BD = [tex]\sqrt{74.65}[/tex]

I.e BD = 8.64

Or, BD = 8.6

Similarly for y

[tex]\dfrac{AC}{AD}[/tex] = [tex]\dfrac{BC}{ED}[/tex]

Or,  [tex]\dfrac{6.9+y}{6.9}[/tex] = [tex]\dfrac{10.2}{5.2}[/tex]

Or, 5.2 × ( 6.9 + y ) = 10.2 × 6.9

Or, 35.88 + 5.2 y = 70.38

or, 5.2 y = 70.8 - 35.88

Or, 5.2 y = 34.5

∴  y = [tex]\frac{34.5}{5.2}[/tex]

I.e y = 6.6

Now in Δ CED

CD² + ED² = CE²

Or, 6.6² + 5.2² = CE²

Or, CE² = 70.6

∴  CE = [tex]\sqrt{70.6}[/tex]

I.e CE = 8.40

Or, CE = 8.4

Hence The measure of side BD is 8.6  and The measure of side CE is 8.4  Answer

Answer:

By using geometric calculations,the measure of BD and CE are 6.9 and 7.4 respectively.

Answer:

3:45 P.M.

Step-by-step explanation:

After I fill the tank, the content settles for 14 hours before the liquid is removed.

So, the liquid is removed after content settlement i.e. after 14 hours of filling up the tank.

If I fill the tank at 1:45 A.M. then after 14 hours i.e. at 3: 45 P.M I will remove the liquid.

If we separate the 14 hours into (12 hours + 2 hours), then by adding 12 hours the time will remain the same, only the A.M. will change to P.M i.e. 1: 45 P.M. and then by adding 2 hours more the time will be 3:45 P.M. (Answer)  

Answer: x=0.5

Step-by-step explanation: In order to solve this problem, you need to simplify the rest of the problem first. You can do this by dividing -7 by 2, which will result in -3.5, making the equation 3x-3.5=-5. If you add 3.5 to both sides, the equation becomes 3x = 1.5. If you divide 1.5 by 3, you are left with 0.5, so x=0.5.

Final answer:

The solution to the linear equation '3x minus 7 divided by 2 equals negative 5' is found by performing algebraic operations to isolate the variable, resulting in x = -1.

Explanation:

The question involves solving a linear equation which is a fundamental concept in mathematics. To solve the equation 3x minus 7 divided by 2 equals negative 5, you will perform algebraic operations to isolate the variable x. Here is a step-by-step process:

Applying this process, you can see that the original equation is satisfied when x = -1, which completes our solution.

Answer:

The answer is definitely C. a naturally formed solid substance with a crystal structure

Answer:  (-7, -4)

========================================

Explanation:

The general equation y = a| x-h | + k has the vertex (h,k)

Rewrite the original function in this form to get f(x) = -1|x - (-7)| + (-4) and we see that h = -7 and k = -4

So that's why the vertex is (h,k) = (-7, -4)

The V shape graph opens downward meaning that the vertex (-7, -4) is at the highest point. The graph is shown below. I used GeoGebra to make the graph.

Answer:

-7,-4

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

First of all,

Since, from the graph we can see that the line is sloping upward, we know the correlation coefficient would be POSITIVE, so we can immediately eliminate choices A & B.

Now, the closer the correlation coefficient value is to 0, the less steep the line is. The closer it is to 1, the more steeper it is.

Looking at the graph, it isn't that flat, it is quite steep. So the correlation coefficient would be 0.8, NOT 0.1

So, answer choice C is right.

Answer:

General formula of slope=change in y/change in x

1:0.25

2:0

For this case we have that by definition, the slope of a line

is given by:

[tex]m = \frac {y_ {2} -y_{1}} {x_ {2} -x_ {1}}[/tex]

Where:

[tex](x_ {1}, y_ {1})\ and\ (x_ {2}, y_ {2})[/tex] are two points through which the line passes.

According to the statement we have:

[tex](x_ {1}, y_ {1}): (3,5)\\(x_ {2}, y_ {2}): (3, -5)[/tex]

Substituting we have:

[tex]m = \frac {-5-5} {3-3}[/tex]

Answer:

m ∠ UVT = 97° is the required answer.

Step-by-step explanation:

Given:

m∠WVU = 169°

m∠WVT = (2x + 20)°

m∠UVT = (3x + 19)°

To Find:

m∠UVT = ?

Solution:

Angle Addition Postulate is that if you place two angles side by side, then the measure of the resulting angle will be equal to the sum of the two original angle measures.

So By applying this property in the diagram below we get,

m∠ WVT + m∠UVT = m∠WVU ............{Angle Addition Postulate}

[tex](2x+20) + (3x+19) = 169\\5x + 39 = 169\\5x=169-39\\5x=130\\\therefore x=\frac{130}{5} \\\therefore x=26\\[/tex]

Now,

m∠UVT = (3x + 19)°

Substituting x = 26 we get

  m∠UVT = 3 ×26 + 19

                = 78 +19

∴ m∠UVT = 97°

The number of weeks requires is 15 weeks

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Steps to Use Unitary Method

First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.

Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.

Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.

Help please thanks

Final answer:

Jason will have to work approximately 6.67 weeks, or about 6 weeks and 5 days, to pay off a $1200 mistake if he earns $4.50 per hour after government income reduction.

Explanation:

To calculate how many weeks a student would have to work to pay for a $1200 mistake, we will use the information provided about Jason's income and work scenario as a reference. According to the information, Jason nets $4.50 for every hour of work due to a reduction in government income. Thus, if Jason has to repay $1200, we will divide this amount by his net hourly income to find the total hours he needs to work.

$1200 ÷ $4.50 per hour = 266.67 hours

Now, to convert these hours into weeks, we assume a standard work week is 40 hours. Therefore, we divide the total hours by 40 hours per week.

266.67 hours ÷ 40 hours per week = 6.67 weeks

Jason will have to work approximately 6.67 weeks to pay off a $1200 mistake.

Answer:

Part a) Camilo is 34 years old and Juan is 28 years old

Part b) The difference between Camilo's age and Juan's age is 6 years

Part c) The sum of the ages of Camilo and Juan not coincide with the age of Andres' grandmother

Step-by-step explanation:

The question in English is

If Camilo is 6 years older than Juan, Juan is 7 years younger than Andrés and Andrés is 35 years old .

Part a)  How old is Camilo and how old is Juan? raises the equation.

Part b) What's the difference between Camilo's age and Juan's age?

Part c) If Andres's grandmother is 65 years old, does the sum of the ages of Camilo and Juan coincide with the age of Andres' grandmother?

Part a)  How old is Camilo and how old is Juan? raises the equation.

Let

x -----> Camilo's age

y -----> Juan's age

z -----> Andres's age

we know that

[tex]x=y+6[/tex] -----> equation A

[tex]y=z-7[/tex] -----> equation B

[tex]z=35[/tex] -----> equation C

Find the value of y

substitute the value of z in the equation B

[tex]y=35-7=28[/tex]

Find the value of x

substitute the value of y in the equation A

[tex]x=28+6=34[/tex]

therefore

Camilo is 34 years old and Juan is 28 years old

Part b) What's the difference between Camilo's age and Juan's age?

Subtract Juan's age from Camilo's age

so

[tex]x-y=34-28=6\ years[/tex]

Part c) If Andres's grandmother is 65 years old, does the sum of the ages of Camilo and Juan coincide with the age of Andres' grandmother?

Adds Camilo's age and Juan's age

[tex]x+y=34+28=62\ years[/tex]

[tex]62\ years\neq 65\ years[/tex]

therefore

The sum of the ages of Camilo and Juan not coincide with the age of Andres' grandmother

Answer:

n = - 3

Step-by-step explanation:

We have to solve the equation [tex]2^{n} = \frac{1}{8}[/tex] for n.

Now, as the variable is in power, we will take a log on both sides.

So, [tex]2^{n} = \frac{1}{8}[/tex]

⇒ [tex]\log 2^{n} = \log \frac{1}{8}[/tex]

⇒ n log 2 = log 1 - log 8 {Since we know the property of logarithm [tex]\log a^{b} = b \log a[/tex] and [tex]\log \frac{a}{b} = \log a - \log b[/tex]}

⇒ n log 2 = -  log 2³ { Since, log 1 = 0}

Required number is [tex]\frac{-13}{5}[/tex] and required expression is n – 10 = 6n + 3

Given that  

Ten less than a number is three more than six times the number.

Number is represented by variable "n"

Need to determine equation and the number.

Ten less than number means subtracting 10 from the number  

As number is n so ten less than number = n – 10   ------(1)

Six times the number = number multiplied by 6 = 6n  

So three more than Six times the number = 6n + 3 --------(2)

As ten less than number is equal to  3 more than six times the number  

=> n – 10  = 6n + 3

Solving the above expression for n we get

-10-3 = 6n – n

=> 5n = -13

[tex]\Rightarrow \mathrm{n}=-\frac{13}{5}[/tex]

Hence required number is [tex]-\frac{13}{5}[/tex] and required expression is n – 10  = 6n + 3

Elena is wrong, because the two sides of equation are not equal for all values of x

Step-by-step explanation:

An equation of x is true for all values of x when the left hand side

is equal to the right hand side

To prove that an equation is true for all values of x do that

Lets check that with given equation 5(x + 2) = 5x + 10

∵ 5(x + 2) = 5x + 10

- Simplify the left hand side

∵ 5(x) + 5(2) = 5x + 10

∴ 5x + 10 = 5x + 10

- Subtract 5x from both sides

∴ 10 = 10

∵ L.H.S = R.H.S

∴ The equation is true for all values of x

Lets do that with Elena's equation

∵ 20(x + 2) = 4(5x + 10) + 31

- Simplify the two sides of the equation

∵ 20(x) + 20(2) = 4(5x) + 4(10) + 31

∴ 20x + 40 = 20x + 40 + 31

- Add like terms in the right hand side

∴ 20x + 40 = 20x + 71

- Subtract 20x from both sides

∴ 40 = 71 ⇒ and that not true

∵ L.H.S ≠ R.H.S

∴ The equation is not true for all values of x

Elena is wrong, because the two sides of equation are not equal for all values of x
