Joy definitely does have enough soup for 22 people.

Step-by-step explanation:

Upper Bound: 285ml  turn it to 0.285 L                      10÷2=5

280ml  :

Lower Bound: 275ml turn it  to 0.275 L

Upper Bound: 6.75 L                           0.5÷2=0.25

6.5 Litters  :

Lower Bound:6.25  L

6.75÷0.275=24.54 or 25  

6.25÷0.285=21.92 or 22Answer:

Answer:

The answer would be B

Step-by-step explanation:

Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle. If you are working with equilateral triangles, divide 180 by three to find the value of X.

Answer:

$7.50

Step-by-step explanation:

$50 x .15 = $7.50

$7.50 estimated to nearest cent is $7.50

Step-by-step explanation:

Given

[tex]f(x) = \frac{x + 5}{x} [/tex]

So

[tex]f(2) = \frac{2 + 5}{2} \\ = \frac{7}{2} [/tex]

Now

[tex] {f}^{ - 1} (x) = \frac{5}{x - 1} [/tex]

So

[tex] {f}^{ - 1} (2) = \frac{5}{2 - 1} \\ = \frac{5}{ 1} \\ = 5[/tex]

Hope it will help :)❤

Step-by-step explanation:

first you will put a line in the missing part of the inside of the figure.Once you do you will see that there are two figures.

to find the diagonal of the half-circle : 7cm-2cm-1cm=4cm

Now use the area formulas for each figure.The area of the semicircle is pi×d/2.The area of the rectangle is a×b.

A of semicircle =3.14×4cm/2=6.28cm²

A of rectangle =7×3=21cm²

to find the perimeter of them:

P of semicircle = 3.14×4=12.56cm

P of rectangle =2(7+3)=14+6=20cm

Answer:

[tex]\frac{3}{2} x[/tex] - 2

Step-by-step explanation:

1/2 (2+ 3x -6)

1/2(3x-4)

3/2x - 2

You do the parentheses first because of PEDMAS.  So 1 combined the 2 and the -6.

Answer:

The first answer (3/2x - 5)

Step-by-step explanation:

You need to multiply 1/2 by 2 which gives you 1.  then when you multiply 1/2 by 3, you can't make it a whole number, so you make it a fraction and it then becomes 3/2x.  Lastly, you do 1/2 times -6 which gives you -3.  The equation goes from 1/2(2+3x-6) to then 1+3/2x-3.  Since 1 and 3 can be subtracted because they're both whole numbers, you do 1-6 which gives you -5.  The answer then becomes 3/2x -5

Hope this helped

4 goes into itself 1 and into 16 4 times then u just multiply the 3 x 4 which is equal to 12 ;)

Answer:

Angle 13 equal 90 and Angle 12 equal 45

Step-by-step explanation:

This is a square so all of the corner angles and the diagonals angles measure 90 degrees. A square also forms 4 congruent isoceles triangles or technically 45-45-90 triangles. So that means the following angles measure 45 degrees since they share a point

Angle 5,6,7,8,9,10,11,12. So the measure of 12 is 90 degrees.

To find the measure of 13, in a square diagonals bisect each other and form perpendicular lines so that means every angle in the middle of the square measure 90 degrees.

Using that

Angle 13,15,16 and R measure 90 degrees so Angle 13 equal 90.

Answer:

7.5 miles per hour

Step-by-step explanation:

Given: Kayla runs 3/4 mile in 1/10 hour assuming she runs at a constant rate

To find: speed in miles per hour

Solution:

Distance travelled by Kayla = [tex]\frac{3}{4}[/tex] mile

Time = [tex]\frac{1}{10}[/tex] hour

To find the speed in miles per hour, use the following formula:

Speed = Distance ÷ Time = [tex]\frac{\frac{3}{4} }{\frac{1}{10} }=\frac{3}{4}(10)=7.5[/tex] miles per hour

Answer:

[-2,4]

Step-by-step explanation:

The domain is just asking for all the possible x values

we can see that the lowest x value is -2 and the highest is 4 which means our answer is

[-2,4]

Answer:

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the

x

-axis. The range is the set of possible output values, which are shown on the

y

-axis. Keep in mind that if the graph continues beyond the portion of the graph we can see, the domain and range may be greater than the visible values.

We can observe that the graph extends horizontally from −5 to the right without bound, so the domain is [−5,∞). The vertical extent of the graph is all range values 5 and below, so the range is (−∞,5]. Note that the domain and range are always written from smaller to larger values, or from left to right for domain, and from the bottom of the graph to the top of the graph for range.

Answer:

Each field has cornstalks = 660

Step-by-step explanation:

P.S - The exact question is -

As given,

There are 2 types of corn - Type A and Type B

Each field has 60 rows

In each row -

Type A corn grow = 8

Type B corn grow = 3

⇒Total corn grow in each row = 8 + 3 = 11

Now,

1 row = 11 cornstalks

⇒60 rows = 60×11 cornstalks = 660 cornstalks

∴ we get

Each field has cornstalks = 660

Answer:

$2,297.76

Step-by-step explanation:

Present value: P = 2000

Future value: F

Annual interest rate: r = 3.5% = 0.035

Time: t = 4 years

Number of compounding periods per year: n = 2

[tex] F = P(1 + \dfrac{r}{n})^{nt} [/tex]

[tex] F = 2000(1 + \dfrac{0.035}{2})^{2 \times 4} [/tex]

[tex] F = 2000(1 + 0.0175)^{8} [/tex]

[tex] F = 2000(1.0175)^{8} [/tex]

[tex] F = 2000(1.148881783) [/tex]

[tex] F = 2297.76 [/tex]
