Find the value of x in the triangle shown below.

Answer:

Y=-1

Step-by-step explanation:

Y-4-4Y=-1

-3Y=-1+4

-3Y=3

Y=3÷-3

Y=-1

Answer:

y = -1

Step-by-step explanation:

y - 4 - 4y = - 1   Combine like terms

y - 4y - 4 = - 1

-3y - 4 = - 1 Add 4 to each side

-3y - 4 + 4 = -1 + 4

-3y = 3 Divide each side by -3

-3y/-3 = 3/-3

y = -1

Answer:

no solutions

Step-by-step explanation:

distribute 7 (n+1) =7n+7=3+7n

subtract 7 from both sides (7n=7n-4)

subtract 7n to get 0=-4

so no solutions

Answer:

243 cm^3

Step-by-step explanation:

The faces of a cube are squares.

A = s^2

s^2 = 9 cm^2

s = 3 cm

The side of the square is the edge of the cube and is 3 cm.

V = s^3

V = (3 cm)^3 = (3 cm)(3 cm)(3 cm) = 27 cm^3

The volume of one cube is 27 cm^3.

The volume of 9 cubes is 9 * 27 cm^3 = 243 cm^3

Answer: 243 cm^3

Answer:

Step-by-step explanation:

Total number of flavors (n) = 12

Number of flavors to combine (r) = 3

Recall:

nCr = n! ÷(n-r)! r!

nCr = 12! ÷ (12 - 3)!3!

nCr = 12! ÷ 9!3!

nCr = (12 * 11 * 10) / (3 * 2 * 1)

nCr = 1320 / 6

= 220 ways

Answer: 0.819

Step-by-step explanation:

Given: X is a normally distributed random variable with mean 95 and standard deviation 3.

Then,  the probability that X is between 89 and 98 will be:

[tex]P(89<X<95)=P(\dfrac{89-95}{3}<\dfrac{X-mean}{standard\ deviation}<\dfrac{98-95}{3})\\\\=P(-2<Z<1)\ \ \ [Z=\dfrac{X-mean}{standard\ deviation}]\\\\ =P(Z<1)-(1-P(Z<2))\\\\= 0.8413- (1-0.9772)\ \ \ [\text{By p-value table}]\\\\= 0.8185\approx0.819[/tex]

Hence, the required probability = 0.819

Answer: 2/3 I got this question on my test to and I got it correct!

Answer:

Below

Step-by-step explanation:

● 3

● 3^2

● 9

● 9 + c

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

Explanation:

3 to the 2nd power is the same as writing 3^2 in shorthand

3^2 = 3 squared

When we square a number, we're multiplying it by itself (having 2 copies total of the number). Think of a square with side length 3 units. Its area is 3^2 = 3*3 = 9 square units.

From here, we add on c to get our answer 9+c. We don't know the value of c, so we cannot evaluate further. Also, 9 and c are not like terms so we cannot combine them.

Your question has been heard loud and clear.

a)

Initial velocity , U=50km/h = 250/18 m/s

Final velocity , V = 0 (this is because the car finally comes to rest)

From 3rd equation of motion , V^2-U^2=2AS.

Now , for a car that goes 50km/h , it has been proven that miniumum brake distance is 6 metres.

so , S = 6 metres.

Using this , we can find the distance stopped by car , and then we can find time.

0-(250/18)^2=2*A*6

0= 2*A*6+(250/18)^2

0 = -12A + 192.90 ( minus sign because car is deccelerating)

So , A = 16.07 m/s^2

V^2-U^2 = 2AS

0 - 192.90 = 2* 16.07*S

So , S (distance) = 24 metres.

Now , we know time = distance / speed

so , time = 24 / 253 = 0.094 seconds

Thank you

Answer:

∠ EFH = 112°

Step-by-step explanation:

∠ ACD and ∠ EFH are Alternate exterior angles and are congruent, thus

11x - 20 = 9x + 4 ( subtract 9x from both sides )

2x - 20 = 4 ( add 20 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12

Thus

∠ EFH = 11x - 20 = 11(12) - 20 = 132 - 20 = 112°

Answer:

The total amount Alex spent is $ 9

Step-by-step explanation:

The given parameters are;

The amount Alex spends on food = 2/3 of his paycheck

The amount Alex spends on coffee = $3

Therefore, we have;

Fraction of the paycheck spent on coffee = 1 - 2/3 = 1/3 of p

The  amount Alex spends on coffee = 1/3 of his paycheck

Therefore, we have;

1/3 × p = $3

p = 3 × $3 = $9

The total amount Alex spent = $ 9

The amount Alex spends on food = 2/3 × $9 = $6.

Answer:

x = -8

Step-by-step explanation:

To answer this equation solve for x. When doing so make sure to get x one side

First subtract 4x from each side. This means the equation is now

x + 6 = -2

Next subtract 6 on both side and you should find x

x = -8

Hey there!

72 athletes can eat for 6 days.

1 athlete can eat for 6(72), or 432 days.

54 athletes can eat for 432/54, or 8 days.

They can eat for 2 more days.

Let me know if this helps :)

Answer:

8 days

Step-by-step explanation:

sufficient food for 72 athlete to last 6 days

when 18 athletes are absent : 72-18=54

multiply scouts by days , to see how many food is packed :

72*6=432

then divide the amount of food packed by the number of scout attended:

432/54= 8 days

Answer:

193.

Step-by-step explanation:

We would solve this question by cross multiplication.

If a sound of fertilizer covers 45 square feet of lawn and the lawn is 8666.7 square feet

To get fertilizer quantity we have

1 pound = 45 square

Unknown = 8666.7 square feet

8666.7/45

= 192.59 when approximated we get 193.

Therefore she has to buy 193 pounds of fertilizer

Answer: b. False

Step-by-step explanation:

The term " correlation" defines the nature of the relationship between the two quantities.

The term "causation" defines the effect of one variable one the other.

They both are used to analyse the relationship between variables such that

Presence of causation implies there is correlation between variables but correlation does not imply causation.

So, correlation coefficient (r) has nothing to do with the cause.

That means having a good correlation of r = 0.71 between the time spent playing video games each week and grade point average for a group of high school boys doesn't imply that playing video games causes students to get lower grades.

Hence, the given statement is False.

Answer: x=-4

Step-by-step explanation:

Answer:

The correct answer is x = -4.

Step-by-step explanation:

To solve this problem, we should first use the distributive property to get rid of the parentheses on the left side of the equation.  This is modeled below:

4(2x - 3) = 11x

8x - 12 = 11x

Then, we should subtract 8x from both sides to move all of the variable terms to the right side of the equation.

-12 = 3x

Finally, we can divide both sides by 3 to get the variable x completely alone on the right side of the equation.

-4 = x

Therefore, the answer to your question is x = -4.

Hope this helps!

Total amount Ari would have saved after 6 months is $220

Step-by-step explanation:

Ari received $100 as a birthday gift and has decided to save this money as well as add $20 of his own money each month. The total money Ari has saved can be estimated using the equation y = 20x + 100, where x is the number of months and y is the total amount of money saved. How much money will Ari have saved after 6 months?

Solution

Given:

g(x) = 20x + 100

where,

x = number of months

g(x) = the total amount of money saved

How much money will Ari have saved after 6 months?

g(x) = 20x + 100

When x = 6

g(x) = 20(6) + 100

= 120 + 100

= 220

g(x) = $220

Total amount Ari would have saved after 6 months is $220

Answer:

Point T is (-1,1)

Step-by-step explanation:

Concept:

If there two points (x1,y1) and (x2,y2) which lies on coordinate plane and them it divided by point p in the ratio m:n then coordinate of point p is given by

p (nx1+mx2)/(m+n),   (ny1+my2)/(m+n)

__________________________________________

Given

points M(-2,-4) and N(1, 5)

ratio : 1:2

point t  is  (2*-2+1*1)/(1+2),   (2*-4+1*5)/(1+2)

=>  (-4+1)/(3),   (-8+5)/(3)

=> -3/3 , 3/3

=> -1, -1

Thus, point T is (-1,1)
