since triangles are similar

4/x = 7x/7

=》 4/x = x

=》x^2 = 4

=》 x = 2

for right triangles a^2 = b^2+c^2

DF^2 = 7^2+2^2 = 53

=》 DF = 7.28

perimeter of DEF = 7 +2+7.28 = 16.28

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:

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]

The number that is in the millions place is 3

The value of each digit in a number is known as the place value. The correct option is C, 3.

The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.

Identification of the place value of a digit in a number:

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.

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.

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:

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)

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.
