Answer:

Total number of loaves of bread sold in [tex]4[/tex] hours is [tex]120[/tex] and [tex]40[/tex] loaves of bread will remain unsold.

Step-by-step explanation:

Given: A bakery produces [tex]2[/tex] batches of bread with [tex]80[/tex] loaves in each batch.

           It sold [tex]30[/tex] loafs each hour.

To find: How many loaves of bread were sold in [tex]4[/tex] hours? How many loaves of bread were left to sell?

Solution:

Total number of loaves of bread produced [tex]=2 \times 80=160[/tex].

Number of  loafs sold each each hour [tex]=30[/tex].

So, number of loafs sold in [tex]4[/tex] hours[tex]=4 \times 30=120[/tex].

Therefore, number of loaves of bread that were remain unsold [tex]=160-120=40[/tex]

Hence, total number of loaves of bread sold in [tex]4[/tex] hours is [tex]120[/tex] and [tex]40[/tex] loaves of bread will remain unsold.

Step-by-step explanation:

first we need to know that redious isn't gien

so we have to find redious

according to Pythagoras theorem

a²+b²=c²

a=√c²-b²

a=17²-15²

a=√(17+15)(17-15)

a=√64

a=8

Step-by-step explanation:

Answer:

x = 27

Step-by-step explanation:

Given

[tex]\frac{2}{3}[/tex] x - 7 = 11 ( multiply through by 3 to clear the fraction )

2x - 21 = 33 ( add 21 to both sides )

2x = 54 ( divide both sides by 2 )

x = 27

The value of x in the equation 2/3x-7 =1 is 12.

The given equation is 2/3x-7 =1.

x is the variable in the equation.

Minus is the operator.

To solve for x add 7 on both sides:

2/3x-7+7=1+7

2/3x=8

Multiply both sides by 3/2.

x=3/2×8

x=12

Hence, the value of x in the equation is 12.

Answer:

D or 176.71 inches squared.

Step-by-step explanation:

the radius is 7.5. put it in a calculator and you get D.

Answer:

[tex]176.7 in^{2}[/tex]

Step-by-step explanation:

The area of a circle is defined as:

[tex]A = \pi r^{2}[/tex]

Where r is the radius and A is the area. We're given the diameter, 15 inches. The radius is half of the diameter, so the radius is therefore 7.5 inches. Now let's take this value back into the formula above:

[tex]A = \pi r^{2} =\pi (7.5)^{2} = 56.25\pi = 176.7 in^{2}[/tex]

So the circle has an area of [tex]176.7 in^{2}[/tex]

Answer:

The percent error is 20%.

Step-by-step explanation:

The general formula is to subtract the actual value from the estimated value, take the absolute value of the difference, divide that answer by the actual value, then multiply it by 100.

So, 20 (estimated) minus 25 (actual) is -5. The absolute value of -5 would be 5, since absolute value is always positive. Divide 5 by the actual value, 25, and you get 0.2. Multiply 0.2 by 100 to get a percent value, and the answer will amount to 20%. Hope this helps.

Answer:

Dilation.

Step-by-step explanation:

From the given picture , it can be seen that the size of trapezoid P'Q'R'S' is decreased from trapezoid PQRS .

Reflection , rotation and translation are rigid motions that produces congruent images and do not change the size of the shapes.

But dilation is not a rigid motion because it changes the size of the shape by using a scale factor.

Hence, the transformation maps trapezoid PQRS onto trapezoid P'Q'R'S' is "Dilation".

A contractor purchases 5 dozen pairs of padded work gloves for $71.40

the unit price will be

total number of gloves

5 pairs

unit cost per glove

=71.40/5

=$14.28 per glove

The estimated cost per pair is

$14.28 per pair

The error is

%Error= 14.28-14.28/14.28*100

%Error= 0.0*100
