56%\100=x/860 the answer is 481.6

56×860=48,160 48,160÷100=481.6

The answer is 481.6, because 56% = 0.56, so just multiply 860 by 0.56 and u get 481.6

You can work at most 20 hours next week. You need to earn at least $90 to cover your weekly expenses. Your dog walking job pays

Vadim26 [7]

Answer:

The answer in the procedure

Step-by-step explanation:

Let

x ----> the dog walking hours

y ----> the car washing hours

we know that

The system of linear inequalities is equal to

$x+y\leq20$ -----> inequality A

$9x+10y\geq 90$ -----> inequality B

Solve the system of inequalities by graphing

The solution is the shaded area

see the attached figure

Two possible combinations of hours are

(10,10) and (0,9)

Verify

For (10,10)

Substitute the value of x and the value of y in both inequalities

Inequality A

$10+10\leq20$

$20\leq20$ -----> is true

Inequality B

$9(10)+10(10)\geq 90$

$190\geq 90$ ----> is true

therefore

(10,10) is a possible solution

For (0.9)

Substitute the value of x and the value of y in both inequalities

Inequality A

$0+9\leq20$

$9\leq20$ -----> is true

Inequality B

$9(0)+10(9)\geq 90$

$90\geq 90$ ----> is true

therefore

(0,9) is a possible solution

If each slab of butter is one cup, and you want to double a recipe that calls for 1 and 2/3 cups of butter, how many slabs of bu

ycow [4]

Answer:

$1\frac{2}{3}\ slabs$

Step-by-step explanation:

Let

x -----> the number of slabs of butter

y ----> the number of cups of butter

we know that

The ratio is

$\frac{x}{y} =\frac{1}{1}$

$x=y$

That means-----> The number of slabs of butter must be equal to the number of cups of butter

In this problem

we have

$y=1\frac{2}{3}\ cups$

Remember that

$x=y$

The number of slabs of butter needed must be equal to the number of cups of butter

therefore

$x=1\frac{2}{3}\ slabs$

Could 10.6cm,5.6cm,and 4.0 cm be rhe length of a triangle

IRINA_888 [86]

Answer: No, sum of two sides is not greater than the tird side.

Step-by-step explanation:

For a triangle, the sum of any of two sides must be greater than the third side.

Given : Measurements for triangle 10.6cm, 5.6cm, and 4.0 cm

Suppose it is possible to have a triangle with given measurements.

But here, 5.6 cm + 4.0 cm= 9.6 cm which is not greater than 10.6 cm

Therefore, a triangle with lengths 10.6cm, 5.6cm, and 4.0 cm is not possible.

A parallelogram has vertex at (-5 , -1) (-2, -1), (-3,-4), and (-6,-4). What is the approximate perimeter of the parallelogram r

Gre4nikov [31]

Answer:

12.4 units

Step-by-step explanation:

We have to find the length of the sides of the parallelogram which is calculated using the formula for Distance

= √(x2 - x1)² + (y2 - y1)² where we are given the vertices (x1, y1) and (x2, y2)

For side A

(-5 , -1) (-2, -1)

= √(-2 -(-5))² + (-1 - (-1))²

= √(-2 + 5)² + (-1 + 1)²

= √3² + 0

= √9

= 3 units

For side B

(-2, -1), (-3,-4)

= √(-3 -(-2))² + (-4 -(-1))²

= √(-3 + 2)²+ (-4 + 1)²

= √-1² + -3²

= √1 + 9

= √10 units

= 3.1622776602 units

Approximately = 3.2 units

For side C

(-3,-4), (-6,-4).

= √(-6 -(-3))² + (-4 - (-4))²

= √(-6 + 3)² + (-4 + 4)²

= √-3² + 0²

= √9

= 3 units

For side D

(-5 , -1), (-6,-4)

= √(-6 - (-5))² + (-4 - (-1))²

= √(-6 + 5)² + (-4 + 1)²

= √-1² + -3²

= √1 + 9

= √10 units

= 3.1622776602 units

Approximately = 3.2 units

From the above calculation , we can see that,

side A = side C

side B = side D

The formula for the Perimeter of a Parallelogram is = 2(Side a + Side b)

= 2(3 + 3.2) units

= 2(6.2) units

= 12.4 units
