Answer:

17.5 yds because Radius is half of the circumference

Step-by-step explanation:

The radius of the circle with a circumference of 35 π yards is 17.5 yards.

The circumference of a circle is the perimeter of a circle. Therefore,

where

r =radius

Therefore,

circumference = 35πyard

35π = 2πr

divide both sides by 2π

35π / 2π = 2πr / 2π

r = 17.5 yards

The total surface area for the given prism is 808 square inches.

The question asks to calculate the surface area of a rectangular prism in square inches. The dimensions given are 1 1/2 ft (length), 2/3 ft (width), and 5/6 ft (height). To convert these measurements to inches, we multiply by 12 since there are 12 inches in a foot. Thus, the dimensions in inches are:

To find the surface area, we calculate the area of each face and then sum them:

Now, add up all the areas of the faces to get the total surface area:

Surface Area = 360 + 288 + 160 = 808 square inches.

Answer:

46x^2 + 73x + 15

Step-by-step explanation:

Expand both equations

Wall = (6x + 7)(8x + 5) = 48x^2 + 56x + 30x + 35 = 48x^2 + 86x + 35

Mural = (x + 4)(2x + 5) = 2x^2 + 5x + 8x + 20 = 2x^2 + 13x + 20

Minus them.

Wall - Mural =

(48x^2 + 86x + 35) - (2x^2 + 13x + 20)

(48x^2 - 2x^2) + (86x - 13x) + (35 - 20)

46x^2 + 73x + 15

Answer:

46x^2 + 73x + 15

Step-by-step explanation:

Expand both equations

Wall = (6x + 7)(8x + 5) = 48x^2 + 56x + 30x + 35 = 48x^2 + 86x + 35

Mural = (x + 4)(2x + 5) = 2x^2 + 5x + 8x + 20 = 2x^2 + 13x + 20

Minus them.

Wall - Mural =

(48x^2 + 86x + 35) - (2x^2 + 13x + 20)

(48x^2 - 2x^2) + (86x - 13x) + (35 - 20)

46x^2 + 73x + 15

Step-by-step explanation:

Answer:

The answer in the procedure

Step-by-step explanation:

we know that

[tex]sin(A + B) = sin A cos B + cos A sin B[/tex]

In this problem we have

[tex]sin(x + \pi)=sin (x)cos(\pi) + cos(x)sin(\pi)[/tex]

Remember that

[tex]sin(\pi) = 0[/tex]

[tex]cos(\pi) = -1[/tex]

substitute

[tex]sin(x + \pi) = sin(x)(-1) + cos(x)(0)[/tex]

[tex]sin(x + \pi) = -sin(x)[/tex]

Final answer:

To prove that sin (x + π) = -sin x, the trigonometric identity for the sine of a sum is used, and by considering the specific values for cos π and sin π, the identity simplifies to the required expression.

Explanation:

To show that sin (x + π) = -sin x, we can use the trigonometric identity for the sine of a sum:

sin (α + β) = sin α cos β + cos α sin β

Applying this identity to sin (x + π):

sin (x + π) = sin x cos π + cos x sin π

Since cos π = -1 and sin π = 0, we substitute these values:

sin (x + π) = sin x (−1) + cos x (0)

sin (x + π) = −sin x + 0

Hence, sin (x + π) = −sin x, demonstrating the original statement.

Answer:

ON MONDAY:  35 mosquitos.

ON TUESDAY: 6 flies.

Step-by-step explanation:

As you can see in the diagram, the frog eats 3 flies for every 7 mosquitoes (for lunch). Then you can expresed this ratio as following:

3:7 or [tex]\frac{3}{7}[/tex]

Based on the table:

-If the frog eats 15 flies on monday, then the number of mosquitos that it eats can be calculated as following:

[tex]\frac{3}{7}=\frac{15}{mosquitoes}\\\\mosquitoes=\frac{15*7}{3}\\\\mosquitoes=35[/tex]

-If the frog eats 14 mosquitoes on tuesday, then the number of flies that it eats can be calculated as following:

[tex]\frac{3}{7}=\frac{flies}{14}\\\\flies=\frac{14*3}{7}\\\\flies=6[/tex]

To evaluate the expression, we follow the order of operations (PEMDAS). The result of the expression is 31.

To evaluate the expression 24 ÷ 3 + 7 ⋅ 2 – 15 ÷ 5 + 6 ⋅ 2, we need to follow the order of operations, also known as PEMDAS. PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Therefore, the evaluated expression is equal to 31.

Answer:

Step-by-step explanation:

(4/5+3/5)+3.5*5

= 7/5+7/2*5

= 7/5+35/2

= 14/10+175/10

= 189/10

= 18.9

Answer:

The value of the expression is 18.9

Step-by-step explanation:

The expression is:

[tex]\bigg( \frac{4}{5}+\frac{3}{5}\bigg)+3.5\times 5[/tex]

The first step is to solve the parenthesis. As both fractions have the same denominator, the numerators must be added:

[tex]\bigg( \frac{4+3}{5}\bigg)+3.5\times 5[/tex]

[tex]\bigg( \frac{7}{5}\bigg)+3.5\times 5[/tex]

The second step is to perform the division between 7 and 5, it is 1.4:

[tex]1.4+3.5\times 5[/tex]

The third step is to perform the multiplication between 3.5 and 5, it is 17.5:

[tex]1.4+17.5[/tex]

The last step is to perform the sum, it is 18.9:

[tex]1.4+17.5=18.9[/tex]

Thus, the value of the expression is 18.9.

Answer: C.

Step-by-step explanation:

All we need to do is add all the number together:

Convert to decimals for easier adding:

2.5+2.5+(3.5*5)+4.25+4.25+5.5=36.50km

Now we convert to a fraction: 36.50=36 2/4km

So the answer is 36 2/4km

Answer:

center:(4,-2)

Radius: 3 units

Step-by-step explanation:

The standard equation of a circle is given as [tex](x-h)^2+(y-k)^2=r^2[/tex], where (h,k) is the center and r is the radius of the circle.

The given equation is [tex](x-4)^2+(y+2)^2=9[/tex].

We compare to the standard equation of the circle to get;

[tex]x-h=x-4[/tex]

[tex]\Rightarrow -h=-4[/tex]

[tex]\Rightarrow h=4[/tex]

and

[tex]y-k=y+2[/tex]

[tex]\Rightarrow -k=2[/tex]

[tex]\Rightarrow k=-2[/tex]

Hence the center of the circle is (4,-2).

Also, we have [tex]r^2=9[/tex]

Therefore [tex]r=\sqrt{9}[/tex]

[tex]r=3[/tex] units.

Answer:

Center at (4,-2); radius: 3
