Answer:

I hope this helps you

Step-by-step explanation:

9/10 + 3/5

= LCM of 10 and 5 =10

= 9/10 + 6/10

= 9+6/10

= 15/10 = 3/2 = 1.5

Answer:

It will be 2x -1

If x=2

2*2 - 1 = 4 - 1 = 3

Step-by-step explanation:

7 - x    If x=2

7 - 2 = 5

11 - 3x   If x=2

11 - 3*2 = 11 - 6 = 5

2x -1   If x=2

2*2 - 1 = 4 - 1 = 3

4x - 3    If x=2

4*2 - 3 = 8 - 3 = 5

Answer:

D

Step-by-step explanation:

24/-3 = -8

since we divided by a negative, we have to flip the symbol to <

x < -8

Answer:

B. Twenty-three dollars is the price for each ticket

Step-by-step explanation:

The answer is B because 1 concert ticker is $23. If you buy 2 concert tickets, the price would go up by x2 $46. You are basically buying $23 for 1 concert ticket and $23 for each 1 concert ticket you buy. Hope this helps

Answer:

[tex]r=1.05\ \text{ft}[/tex]

[tex]h=2.12\ \text{ft}[/tex]

[tex]20.91\ \text{ft}^3[/tex]

Step-by-step explanation:

r = Radius

h = Height

Volume of cylinder = [tex]7.35\ \text{ft}^3[/tex]

[tex]V=\pi r^2h\\\Rightarrow h=\dfrac{V}{\pi r^2}\\\Rightarrow h=\dfrac{7.35}{\pi r^2}[/tex]

Surface area is given by

[tex]A=2\pi r^2+2\pi rh\\\Rightarrow A=2\pi r^2+2\pi r\dfrac{7.35}{\pi r^2}\\\Rightarrow A=2\pi r^2+\dfrac{14.7}{r}[/tex]

Differentiating with respect to radius we get

[tex]\dfrac{dA}{dr}=4\pi r-\dfrac{14.7}{r^2}[/tex]

Equating with zero we get

[tex]0=4\pi r-\dfrac{14.7}{r^2}\\\Rightarrow 4\pi r=\dfrac{14.7}{r^2}\\\Rightarrow r^3=\dfrac{14.7}{4\pi}\\\Rightarrow r=(\dfrac{14.7}{4\pi})^{\dfrac{1}{3}}\\\Rightarrow r=1.05[/tex]

[tex]\dfrac{d^2A}{dr^2}=4\pi-2\times \dfrac{14.7}{r^3}\\\Rightarrow \dfrac{d^2A}{dr^2}=4\pi+2\times \dfrac{14.7}{1.05^3}\\\Rightarrow \dfrac{d^2A}{dr^2}=37.96>0[/tex]

So, the value of the function is minimum at [tex]r=1.05[/tex]

[tex]h=\dfrac{7.35}{\pi r^2}=\dfrac{7.35}{\pi 1.05^2}\\\Rightarrow h=2.12[/tex]

So, the radius and height which would minimize the surface area is 1.05 feet and 2.12 feet respectively.

Surface area

[tex]A=2\pi r^2+2\pi rh\\\Rightarrow A=2\pi \times 1.05^2+2\pi 1.05\times 2.12\\\Rightarrow A=20.91\ \text{ft}^3[/tex]

The minimum surface area is [tex]20.91\ \text{ft}^3[/tex].

Answer: I'm not sure i understand. Are you asking a question or is this just a statement

Step-by-step explanation:

Answer:

Gloria would text 360 words if Erica texted 500 words.

Step-by-step explanation:

Let 'y' be the number of words Gloria texts

Let 'x' be the number of words Erica texts

Given that the relationship is  proportional

y ∝ x

y = kx

where 'k' is called the constant of proportionality

Given

substituting the values to determine the constant of proportionality 'k'

k = y / x

   = 18 / 25

Thus, the constant of proportionality = k = 18/25

When Erica texted 500 words, we need to determine the number of words Gloria will text.

so

k = 500

y = ?

k = y / x

y = kx

  = 18 / 25 × 500

  = 360 words

Thus, Gloria would text 360 words if Erica texted 500 words.

Answer:

D. 24 degree

Step-by-step explanation:

Sides of the triangle are

a = 330 ft

b = 180 ft

c = 420 ft

From cosine rule we have

[tex]\angle A=\cos^{-1}(\dfrac{b^2+c^2-a^2}{2bc})\\ =\cos^{-1}(\dfrac{180^2+420^2-330^2}{2\times180\times 420})\\ =48.65^{\circ}[/tex]

[tex]\angle B=\cos^{-1}(\dfrac{a^2+c^2-b^2}{2ac})\\ =\cos^{-1}(\dfrac{330^2+420^2-180^2}{2\times 330\times 420})\\ =24.17^{\circ}[/tex]

[tex]\angle C=\cos^{-1}(\dfrac{a^2+b^2-c^2}{2ab})\\ =\cos^{-1}(\dfrac{330^2+180^2-420^2}{2\times 330\times 180})\\ =107.19^{\circ}[/tex]

The smallest angle in the triangle is [tex]\angle B=24.17^{\circ}[/tex].

Answer:

-2 (x -3 ) = 16 (use the distributive property)

-2x +6 = 16 (subtract 6 from both sides)

-2x = 10 (divide both side by -2)

x= -5

Step-by-step explanation:

y=mx+b

Answer:480

Step-by-step explanation:

Answer:

A. [tex] y = \frac{1}{4}x + 2 [/tex].

Step-by-step explanation:

Equation of a line in slope-intercept form, is given as [tex] y = mx + b [/tex].

Given a slope (m) of ¼, and y-intercept (b) of 2, we can get the equation if the line by substituting m = ¼, and b = 2 into [tex] y = mx + b [/tex].

Thus, the equation of the line would be:

[tex] y = \frac{1}{4}x + 2 [/tex].

Answer: m= -9

Step-by-step explanation: First use distributive property, -4(m) is -4m and -4(3) is -12. Then you have -4m -12 =24. Then use 12 and add it to the other side of the equation, cause of the subtraction sign, 12+24=36. Then you have -4m=36. Then divide the 4 to get the m by its self. 36 divided by -4 is -9. Your answer is m=-9

Answer:

idek

Step-by-step explanation:

Answer:

1.63

Step-by-step explanation:

Answer:

Step-by-step explanation: First, you isolate x, meaning only x can be on one side. you subtract 3 from both sides, getting x<4- x is less than four.

there are two graphs showing x less than four, but since this is less than and not less than/equal to, your answer is the fourth graph, where the point is open and not closed.

Answer:

Last choice,

open circle on 4 arrow going left.

Step-by-step explanation:

X + 3 < 7

x < 4

Answer:

No, it isn't.

Step-by-step explanation:

The point on y = 5 should be on y = 7, and the point on x = 5 should be on x = 7. The attachment shown is what the graph should look like.

Answer:

(3p + 5)^2

Step-by-step explanation:

9p^2 + 30p + 25

9p^2 is the square of 3p = a

25 is the square of 5 = b

This may be the square of a binomial.

We need to check the middle term.

(a + b)^2 = a^2 + 2ab + b^2

2ab = 2(3p)(5) = 30p

This is the square of a binomial.

9p^2 + 30p + 25 = (3p + 5)^2

Answer:

0.25(7x-6y)

Step-by-step explanation:

Two numbers on each die are squares: 1 and 4. 4 numbers on each die are not squares: 2 , 3, 5, and 6. there are 16 ways for him to roll a non-square die, out of 36 outcomes for the pair of dice. The other 20 options each have a square number showing on one or both dice. So, the probability is 5/9. hope this helps please pick my answer as brainliest, have a good day!
