There are 4 sticks, you pick up one stick. How many sticks are left

LenaWriter [7]

There are 3 sticks because:

4 sticks is the total and when you take away 1 stick, it is

4 - 1, which equals 3 sticks

So, the answer is 3 sticks are left.

Question: If u are in high school, why did you ask this question? You already know 4-1=3. Im guessing it was either a joke, or u were helping other people get points. If it is the second one, thx!!

Find the value of x and y

Romashka [77]

Step-by-step explanation:

$\triangle ABC \sim\triangle DEF..(Given) \\ \therefore \frac{AB}{DE} =\frac{BC}{EF}=\frac{AC}{DF}..(CSST)\\\\\therefore \frac{6}{4} =\frac{7}{x}=\frac{8}{y}\\\\ \therefore \frac{6}{4} =\frac{7}{x} \\ \therefore \: x = \frac{7 \times 4}{6} \\ \\\therefore \: x = \frac{28}{6} = \frac{14}{3} \\ \\ \huge \red{ \boxed{ \therefore \: x = \frac{14}{3} }} \\ \\ \because \: \frac{6}{4} =\frac{8}{y} \\ \\ \therefore \:y = \frac{4 \times 8}{6} \\ \\ \therefore \:y = \frac{32}{6} \\ \\ \huge \purple{ \boxed{ \therefore \:y = \frac{16}{3} }}\\ \\$

Wheeler Company can produce a product that incurs the following costs per unit: direct materials, $10.30; direct labor, $24.30,

salantis [7]

Answer:

Incremental cost of buying = $2.50

Step-by-step explanation:

Cost per unit;

Direct materials = $10.30

Direct labor = $24.30

Overhead = $16.30

Total Overhead cost = 10.30 + 24.30 + 16.30

= $50.90

Where the item is purchased,

Total cost = $46.88 + (40% × 16.30)

= $46.88 + $6.52

= $53.40

Cost difference = $53.40 - $50.90

= $2.50

There is an incremental cost of buying. This amounts to $2.50

2x-y²=1<br> 3x+y=4 <br> Heelp...

bogdanovich [222]

So first we solve for y in second equation
3x+y=4
y=4-3x
sub for y in first equiton
2x-(4-3x)^2=1
2x-(16-12x-12x+9x^2)=1
2x-(16-24x+9x^2)=1
2x-16+24x-9x^2=1
-9x^2+26x-16=1
times -1 both sides
9x^2-26x+16=-1
add 1 to both sides
9x^2-26x+17=0
factor
(x-1)(9x-17)=0
set each to zero
x-1=0
x=1

9x-17=0
9x=17
x=17/9

so sub back to find y
y=4-3x
y=4-3(1)
y=4-3
y=1
(1,1)

y=4-3x
y=4-3(17/9)
y=4-17/3
y=12/3-17/3
y=-5/3
(17/9,-5/3)

the 2 intersection points are
(1,1) and $( \frac{17}{9} , \frac{-5}{3} )$
