the product of -5 and the number is 35 what is the number
a. 40
b. 30
c. -7
d. 7

Answer:

5 and 7

Step-by-step explanation:

The two-sided limit exists as long as the limits from either side also exist and are equal. So to compute the limit, you have to compute the one-sided limits,

[tex]\displaystyle\lim_{x\to0^-}f(x)[/tex]

[tex]\displaystyle\lim_{x\to0^+}f(x)[/tex]

f(x) has a different definition and thus different behavior as x approaches 0 depending on which direction x is approaching 0:

• When x approaches 0 from the left (or from below), you use the definition of f for x < 0, so

[tex]\displaystyle\lim_{x\to0^-}f(x) = \lim_{x\to0}(-x-2) = -2[/tex]

• When x approaches 0 from the right (or above), you use the other definition, so

[tex]\displaystyle\lim_{x\to0^+}f(x) = \lim_{x\to0} \left(\frac x2-2\right) = -2[/tex]

The limits from either side match, so the two-sided limit exists and is also -2.

Answer:

f(3)= 33

Step-by-step explanation:

Answer:

1/5^8 ⋅ 5^5

Step-by-step explanation:

Answer:

[tex]\frac{1}{5^{3} }[/tex]

Step-by-step explanation:

Using the rules of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex] ,  [tex]a^{-m}[/tex] = [tex]\frac{1}{a^{m} }[/tex]

[tex]5^{-8}[/tex] × [tex]5^{5}[/tex]

= [tex]5^{(-8+5)}[/tex]

= [tex]5^{-3}[/tex]

= [tex]\frac{1}{5^{3} }[/tex]

Answer:

5 seconds

Step-by-step explanation:

When the rocket is on the ground, then h = 0 , that is

- 6t² + 30t = 0 ← factor out - 6t from each term

- 6t(t - 5) = 0

Equate each factor to zero and solve for t

- 6t = 0 ⇒ t = 0 ← when rocket is launched

t - 5 = 0 ⇒ t = 5 ← time when rocket returns to ground

Answer:

B is our answer 12.56

When finding area for circles we do

radius x radius x pi

Since we don't have the radius in the problem we have to figure it out but it wont be so hard knowing that the radius is half of the diameter so 4 ÷ 2 = 2 so 2 is our radius now we need tp square it in easier words multiply by itself so

2 x 2 = 4 then we just do 4 x pi!

So 4 x 3.14 = 12.56 So our answer is 12.56

Answer: Rose used 2.075 pints of blue paint for her bedroom walls

Step-by-step explanation:

Amount of white and blue paint used for bedroom walls=8.3 pints

Amount of white paint used =3/4 x8.3 pints =6.225 pints

Amount of blue paint used = Amount of white and blue paint used for bedroom walls-Amount of white paint used

8.3 pints - 6.225 pints=2.075 pints

Answer:

x = 25

Angle B = 65 degrees

Angle C = 50 degrees

Step-by-step explanation:

All triangles will add up to 180 degrees.

65 + 3x - 10 + 2x = 180

Combine like terms

55 + 5x = 180

Subtract both sides by 55

5x = 125

Divide both sides by 5

x = 25

Plug in the value for x in angle B:

3(25) - 10

75 - 10

65

Do the same for angle C:

2(25)

50

Check your work:

65 + 65 + 50 = 180

180 = 180

Correct

Answer:

The correct option is (b).

Step-by-step explanation:

Given that,

The radius of the circle, r = 8 cm

The area of the sector, [tex]A=56\pi \ cm^2[/tex]

We need to find the measure of the sentral angle. The formula for the area of a sector is given by :

[tex]A=\dfrac{1}{2} r^2\theta[/tex]

Where

[tex]\theta[/tex] is the central angle

Substitute all the values,

[tex]\theta=\dfrac{2A}{r^2}\\\\\theta=\dfrac{2\times 56\pi }{8^2}\\\\\theta=\dfrac{7\pi}{4}\ rad[/tex]

So, the correct option is (b).

Answer:

z = -2.13

The standardized score for the state of Colorado is negative and this means the score is smaller than the mean.

Step-by-step explanation:

The above question can be solved using z score.

The formula for z score is given as:

z = (x-μ)/σ,

where

x is the raw score = 9.7%

μ is the population mean = 13.26%

σ is the population standard deviation = 1.67%

z = z score or standardize score

Hence,

z = 9.7 - 13.26/1.67

z = -2.13174

Approximately z = -2.13

Therefore, the standardized z score for the state of Colorado is negative and this indicates that the score is below or smaller than the mean.

Answer:

always catchin em lackin

Step-by-step explanation:

Answer:

The answer is D

Step-by-step explanation:

the standard equation for circle is (x －h)² ＋(y －k)² = r² which h is the x coordinate, k is the y coordinate, r is radius. In this case, both x coordinate and y coordinate are 0, so the left side of the equation is x² + y², since the radius is √249, the r² is 249. So the equation is x² + y² = 249, and the answer is D.

Answer:

40[tex]cm^{3}[/tex]

Step-by-step explanation:

The volume of the rectangular prism is equal to...

L x W x H    (where L is length, W is width, and H is the height)

Therefore we know that the volume of this rectangular prism is...

L x W x H

8cm x 1cm x 5cm = 40[tex]cm^{3\\}[/tex]

Answer:

B) h = 3V/πr²

Step-by-step explanation:

Answer:

Step-by-step explanation:

1)

a/c =b/d  where a=27 c=30 b=x d=18

27/30 = x/18

27*18/30=x

16.2 = x

2)

a/c =b/d  where a=2x-5 c=x+11 b=16 d=14

2x-5 / x + 11  = 16 / 14

14(2x-5) = 16(x+11)

28x - 70 = 16x + 176

12x = 246

x = 20.5

3)

6+15 / 7+x  = 7 /6

6(6+15) = 7(7+x)

6*21 = 49 +7x

126 = 49 +7x

77 = 7x

11 = x

4)

3*[(x-6)+3]=[tex]6^{2}[/tex]

3(x-3) = 36

3x-9 = 36

3x = 45

x = 15

3.25 :)

Step-by-step explanation:

Answer:

3.25

Step-by-ste

Answer:

130

Step-by-step explanation:

? is an exterior angle of a triangle

An exterior angle is equal to the sum of the two opposite interior angles ( 35 and 95 in this case )

That being said the missing angle = 95 + 35

95 + 35 = 130

Hence, the answer is 130

Answer:

130

Step-by-step explanation:

1. We have a triangle and all angles in a triangle sum up to 180, so do 35+95 and then subtract the difference from 180, and you get 50

2. Now we have a linear pair next to 50' on the outside, signifying a linear pair, meaning that both angles should sum up to 180, so 180-50= 130

Answer:

Mel's height is 159cm, her brother's height is 177cm and their grandma's height is 166cm.

Step-by-step explanation:

Let the grandma's height be g cm.

Mel's height= (g -7) cm

Brother's height= (g +11) cm

Total height

= Mel's height +brother's height +grandma's height

= g -7 +g +11 +g

= (3g +4) cm

Given that their total heights is 502 cm,

(3g +4) cm= 502 cm

3g +4= 502

3g= 502 -4 (-4 on both sides)

3g= 498

g= 166 (÷3 on both sides)

To find their heights, substitute g= 166 back into the expressions.

Grandma's height= 166cm

Mel's height

= 166 -7

= 159cm

Brother's height

= 166 +11

= 177cm

Answer:

x = 14.4

Step-by-step explanation:

Using dilations, the following equation can be written to show the relationship between the two similar triangles:

x/4 = (6.5 + 2.5)/2.5

x/4 = 9/2.5

Cross multiply

x*2.5 = 9*4

2.5x = 36

2.5x/2.5 = 36/2.5

x = 14.4

Answer:

B) The speed of the car depends on the distance traveled
