(1/3)⁷

Answer:

B

Step-by-step explanation:

Because 4 times 3.5 equals 14 and minus 3 equals -11 so its B.

Answer:

Your answer is B.

Step-by-step explanation:

The reason is because:

3-4x=-11

turns to

-4x=-14

when you subtract 3 from both sides then divide both sides by negative 4

and you get:

x=-14/-4

if you simplify -14/-4 your final answer will be

7/2 which equals 3.5:    x=3.5

Answer: 18 quarts

Step-by-step explanation:

As per given,

Quantity of sparkling juice is proportional to quantity of course with grape juice.

Given: A free cable sparkling juice calls for [tex]1\dfrac12[/tex] quarters of sparkling water and [tex]\dfrac34[/tex] course with grape juice .

Let x be the quantity of sparkling water need to mix with 9 quarts of grape juice.

then, by equation of direct proportion , we have

[tex]\dfrac{1\dfrac12}{\dfrac34}=\dfrac{x}{9}\\\\\Rightarrow\dfrac{\dfrac{3}{2}}{\dfrac{3}{4}}=\dfrac{x}{9}\\\\\Rightarrow\ \dfrac21=\dfrac{x}{9}\\\\\Rightarrow\ x=9\times2\\\\\Rightarrow\ x=18[/tex]

Hence, the quantity of sparkling water need to mix with 9 quarts of grape juice = 18 quarts

The midpoint of the line segment is (2,5) (option B)

When given the end points of a line segment, you can find out its midpoint by using the midpoint formula. As the name might have already suggested, midpoint is basically the halfway between two end points. All you need to do is dividing the sum of x-values and the sum of y-values by 2.

The sum of x coordinate is -1+5 = 4

half of sum of x coordinate = 4/2 = 2

The sum of y coordinate = 5+5= 10

half of sum of y coordinate = 10/2 = 5

therefore the midpoint of the line is ( 2,5)

The required inequalities are x + y ≤ 10 and 5x + 10y ≥ 50

A relationship between two expressions or values that are not equal to each other is called inequality.

Given that, You work as a cashier for a grocery store and earn $5 per hour. You also mow lawns and earn $10 per hour. You want to earn at least $50 per week, but would like to work no more than 10 hours per week.

Let, you work at grocery story (x), and you work mowing lawns (y)

You want to work no more than 10 hrs

So, first inequality will deal with hrs.

x + y ≤ 10....(i)

A less than or equal to sign tells that you do not want to work more than 10 hrs, but you can still work 10 hrs, so we include the equal sign as well.

And,

Grocery store (x) earning $5 per hr and lawn mowing (y) earning $10 per hr, making at least $50...

Now we will make an inequality dealing with the $

5x + 10y ≥ 50.....(ii)

A greater than or equal to sign tells that, you want to make 50 or more, so we include the equal sign.

So, the inequalities are :

x + y ≤ 10

5x + 10y ≥ 50

A. Function before discount:

f(c)= 8.97c

This means that cost per strand of outdoor light is $8.97 and c is number of strands of outdoor light bought. Therefore to model the function g(c) after he has received a $5 discount on his purchase(total purchase)

g(c)=8.97c-5

B. cost of 6 strands of light before discount

f(c)= 8.97×6= $53.82

The alternative hypothesis is:

[tex]H_a: \mu > 30[/tex]

This is a right-tailed test since the alternative hypothesis is greater than 30

Suppose the level of significance is 0.05 and we are given a p-value less than  0.05.

Then, we reject the null hypothesis.

Answer:B 19.1 feet

Step-by-step explanation:

The value of the x is 19.1 feet.

"It is an ordered pair of numbers a and b, written [tex]\frac{a}{b}[/tex] where b does not equal 0."

"When two ratios are equal then they are said to be in proportion."

For given question,

A small triangle has a base of 1.7 feet and height of 9.3 feet.

A larger triangle has a base of 3.5 feet and height of x feet.

Since it is the enlargement of the triangle, the sides of both the triangle must be in proportion.

[tex]\Rightarrow \frac{1.7}{3.5}= \frac{9.3}{x}\\\\\ \Rightarrow 1.7\times x=3.5\times 9.3\\\\ \Rightarrow 1.7\times x=32.55\\\\ \Rightarrow x=19.14[/tex]

Therefore, the value of the x is 19.1 feet.

Answer:

AB = 20 units

Step-by-step explanation:

Given the coordinate midpoint M(4.-2) and A(-2,6), we are to find the length AB. To get that, we need to get the coordinate of B first as shown

M(X, Y) = [(x1+x2/2, y1+y2/2]

X = x1+x2/2

4 = -2+x2/2

8 = -2+x2

x2 = 8+2

x2 = 10

Y = y1+y2/2

-2 = 6+y2/2

-4 = 6+y2

y2 = -4-6

y2 = -10

Hence the coordinate of B is (10, -10)

Recall that A =(-2, 6)

Get AB;

AB = √(x2-x1)²+(y2-y1)²

AB = √(-2-10)²+(6+10)²

AB = √(-12)²+(16)²

AB = √144+256

AB = √400

AB = 20 units
