Answer:7 3/5

Step-by-step explanation: 3 4/5 blueberries = 2 2/3 strawberries

                                               ? blueberries    =5 1/3 strawberries

do 3 4/5 times 5 1/3 which gives you 20 4/15.Now divide 20 4/15 by 2 2/3 which gives you 7 72/120 and you can simplify to 7 3/5.

Answer:

D

Step-by-step explanation:

Given:

A piecewise function

[tex]f(x)=\begin{cases}3 &,x<0 \\ x^2+2 &,0\leq x<2 \\ \dfrac{1}{2}x+5 &,x\geq 2 \end{cases}[/tex]

To find:

The range of the function.

Solution:

Range is the set of output values.

For [tex]x<0[/tex], the function is [tex]f(x)=3[/tex]       ...(i)

For [tex]0\leq x<2[/tex], the function is [tex]f(x)=x^2+2[/tex].

[tex]0\leq x<2[/tex]

Squaring each side.

[tex]0^2\leq x^2<2^2[/tex]

Adding 2 on each side.

[tex]0+2\leq x^2+2<4+2[/tex]

[tex]2\leq f(x)<6[/tex]               ...(ii)

For [tex]x\geq 2[/tex], the function is [tex]f(x)=\dfrac{1}{2}x+5[/tex].

[tex]x\geq 2[/tex]

Divide both sides by 2.

[tex]\dfrac{1}{2}x\geq 1[/tex]

Adding 5 on each side.

[tex]\dfrac{1}{2}x+5\geq 1+5[/tex]

[tex]f(x)\geq 6[/tex]                 ...(iii)

From (i), (ii) and (iii), it is clear that the values of f(x) lies in the interval [2,∞).

So, the range of the given function is [2,∞).

Therefore, the correct option is b.

correct answer is B

Answer:

77.6

Step-by-step explanation:

Given the data:

Weighting :

First exam = 20% ; second exam = 30% ; third exam = 50%

Scores :

First exam = 67 ; second exam = 84 ; third exam = 78

Weighted Average :

Σ(Weight * Score)

Σ[(0.2 * 67) + (0.3 * 84) + (0.5 * 78)]

13.4 + 25.2 + 39

= 77.6

Based on the weights assigned to these grades, Emily's weighted average in the class would be 77.6 marks.

= ∑ (Percentage of grade x Score in exam)

Solving gives:

= (20% x 67) + ( 30 % x 84) + (50% x 78)

= 13.4 + 25.2 + 39

= 77.6

Emily's weighted average is 77.6 marks.

Answer:

-2<x<8

see below for graph

Step-by-step explanation:

First, we need to solve the inequality.

Inequality: |x-3|<5

Split into two equations:

x-3<5

x-3>-5 (notice how the sign is flipped when we make the number negative)

let's start with x-3<5

add 3 to both sides

x<8

now

x-3>-5

add 3 to both sides

x>-2

The graph is below

the intersection is the solution.

Notice how I made the maroon line go to the right- which shows that it's greater than (for x>-2) and the silver line go to the left, which shows that it's less than (for x<8)

the equation is -2<x<8

Answer:

29%

Step-by-step explanation:

210-150/210 = 60/210 or 6/21

Now we have to find the percent out of 100 so we have to find out 100/21 to see what we have to multiply by to get to 100 so we can do the same with the 2 (numerator) so 1000/21= 4 16/21

then we have to multiply the 6 by 4 16/21 which is about 29%

Answer:

y = 103

y = 180 - 77 = 103

Step-by-step explanation:

........

Answer:

103

Step-by-step explanation:

All we have to do is subtract the measure of the line which is 180 by 77 to get the measure of < y. Since they are adjacent to each other this concept will work but if they weren't it would be a little different.

[tex]y+77=180\\y=130[/tex]

So the measure of < y is 130°

Answer:

370 millimeters of compound B is needed for 666 millimeters of solution.

Step-by-step explanation:

Given that:

4 millimeters of compound A are used for every 5 millimeters of compound B.

The scientist wants to make 666 millimeters of solution.

Let,

x be the multiplier number of the compounds in the solution.

Then,

4x + 5x = 666

9x = 666

Dividing both sides by 9

[tex]\frac{9x}{9}=\frac{666}{9}\\x=74[/tex]

Millimeters of compound B = 5x = 5(74) = 370 millimeters

Hence,

370 millimeters of compound B is needed for 666 millimeters of solution.

Answer:

To solve the problems in this lesson, students use the slope formula, which states that m = (y2 -- y1) / (x2 -- x1). The slope formula can be read as "slope equals the second y coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate".

Answer:

(-5, -3)

Step-by-step explanation:

To graph the two equations, you can look at two things, the slope and the y-intercept.

The two equations are in slope-intercept form, y= mx + b. m is the slope and b is the y-intercept. The slope is rise/run and the y-intercept is where the line crosses the y-axis.

In the first equation, the slope is -1 and the y-intercept is -8. So, to graph you would start at (0, 8) and move up one unit and then left one unit to get the next point.

For the second equation, the slope is 2/5 and the y-intercept is -1. So, to graph you would do the same thing. Start at (0, -1) and then go up 2 units and right 5 units to get the next point.

Answer:

hmm ..

just transfer the X at the right side and others on left side

Step-by-step explanation:

so you get

w-z = yx

so later

(w-z)/y = x

The required value of x for the equation w - yx = z  is (w - z)/y.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

The given equation is,

w - yx = z

Solve to determine the value of x,

Subtract w from both the sides,

w - yx - w = z - w

-yx = z - w

Multiply with -1 both the sides,

yx = w - z

⇒x = (w - z)/y

The value of x for the given equation is (w - z)/y.
