Jada is making circular invitations

we have d=12 cm, the radius r=6

she needs to find out the circumference

C=2x3.14x r

C=2x 3.14x6=37.68

180/37.68=4.77

she can make just 4 invitations

Answer: x = 3

Step-by-step explanation:

first, we calculate.

27 - 25x = -63 + 5x

then, we move the terms around.

-25x - 5x = -63 - 27

next, we collect the like terms.

-30x = -90

finally, we divide both sides.

x = 3

Given:

In Miss Rogers science class, 32%, 33%, 11%, 5% of students have A, B, D, F respectively.

To find:

The percent of the students have a C in Miss Rogers science class.

Solution:

We know that, sum of the percentages of all parts of pie chart is 100%. So,

[tex]A+B+C+D+F=100\%[/tex]

Substituting the given values, we get

[tex]32\%+33\%+C+11\%+5\%=100\%[/tex]

[tex]C+81\%=100\%[/tex]

[tex]C=100\%-81\%[/tex]

[tex]C=19\%[/tex]

So, 19% of the students have a C in Miss Rogers science class.

Therefore, the correct option is C.

Answer:

4/3 or

Step-by-step explanation:

Let's get this equation into y=mx+b form.

m=slope b=y-int

Subtract 5 from both sides to isolate y on a side.

4x-6=3y

Divide both sides by 3 to isolate y on one side.

(4/3)x-2=y

y=(4/3)x-2

m=4/3

b=-2

So our slope is 4/3

Answer:

A = 27π cm²

Step-by-step explanation:

Area of the shaded region = area of full circle of O - Area of the unshaded sector

= (πr²) - (θ/360*πr²)

Where,

r = 6 cm

θ = 360

Area of shaded region = (π*6²) - (90/360*π*6²)

= (36π) - (¼*π*36)

= 36π - 9π

Area of shaded region = 27π cm²

Answer:

The speed of the truck is 1,200 miles.

Step-by-step explanation:

Car = 10 MILES PER HOUT FASTER THAN THE TRUCK.

Truck = X times 10

X = 120 MILES times 10

120 times 10= 1,200, BECAUSE IF YOU TAKE THE "1" FROM "10" IT'LL BE "1" FROM THE 10, TIMES 120 MILES WHICH = 120. NOW TAKE THE "0" FROM THE 10 AND ADD *0* AT THE END OF THE ANSWER YOU GOT WHICH WAS "120." THEN YOUR ANSWER WILL BE 1,200 IF YOU ADD THE "0" AT THE END.

Answer:

1.39

Step-by-step explanation:

Creating a table:

X :___0 __ 1 __ 2 ___ 3 ____ 4 ___ 5 ___ 6

P(x):0.02_0.03_0.07, 0.12, 0.30_ 0.28_0.18.

The standard deviation = sqrt(Var(x))

Var(x) = Σx²*p(x) - E(x)²

E(x) = ΣX*p(x)

E(x) = (0*0.02) + (1*0.03) + (2*0.07) + (3*0.12) + (4*0.30) + (5*0.28) + (6*0.18) = 4.21

Var(X) :

((0^2*0.02) + (1^2*0.03) + (2^2*0.07) + (3^2*0.12) + (4^2*0.30) + (5^2*0.28) + (6^2*0.18)) - 4.21^2

19.67 - 17.7241

= 1.9459

Standard deviation = sqrt(Var(X))

Standard deviation = sqrt(1.9459)

Standard deviation = 1.3949551

= 1.39

Answer: 11 is the answer.

there are 11 2/7's in 3 with a remainder of 1/7, 11 1/7.

Step-by-step explanation:

Answer:

10.5 or 21/2

Step-by-step explanation:

The question is asking how many 2/7 are in 3. So let make 3 a equivalent fraction that has 7 as it denomanater. 7/7 is 1, 14/7 is 2, so 21/7 is 3. Now let divide 21/7 by 2/7.  flip 2/7 around to 7/2 then multiply by 21/7 which equals

[tex]\frac{147}{14}[/tex] which equals 10.5 or 21/2.

Step-by-step explanation:

14. y = x²+4x+1

    y=x+1

x+1 = x²+4x+1

x²+3x=0        x(X+3)=0

x=0 or x=-3

18. y=x²-3x-20

y=-x-5

-x-5 = x²-3x-20         x²-2x-15 = 0      (x-5)(x+3) = 0

x=5 or x=-3

20. y=x²+5x+1

y=x²+2x+1

x²+2x+1 = x²+5x+1            3x = 0

x = 0

22. y=-x²-3x-2

y=x²+3x+2

x²+3x+2 = -x²-3x-2        2x²+6x+4 = 0    2(x²+3x+2) = 2 (x+1)(x+2) = 0

x = -1 or x = -2

Answer:

{0.99, 5.01, 5.25, 6.79, 6.99, 7.50, 7.51}   second option

Step-by-step explanation:

You can see from the histogram that there is

- one value = 0.99  that is from 0 to  2 dollars and 50 cents

- no values between 2 dollars and 51 cents and 5 dollars

- 5 values between  5 dollars and 1 cent to 7 dollars and 50 cents

-1 value between  7 dollars and 51 cents to 10 dollars

All the four bars the value of dollar fall between the range of 0 dollar to the 10 dollar. This condition satisfy only by the option C.

Hence, The option C is the correct option which is,

{0.75, 2.50, 7.50,7.50,7.50,7.50,10.00}

Given-

Histogram titled number of Items Sold with Price Range on the x axis.

Histogram titled number of Items Sold on the y axis.

The range of bar 1 is 0 to 2 dollars and 50 cents and has a height of 1. As 1 dollar has 100 cents hence 50 cent will be equal to the 0.50 dollar. Thus the range of bar 1 is 1 to 2.5 dollar.

The range of Bar 2 is 2 dollars and 51 cents to 5 dollars and has a height of 0. As 1 dollar has 100 cents hence 50 cent will be equal to the 0.50 dollar. Thus the range of bar 2 is 2.51 to 5 dollar.

The range of bar 3 is 5 dollars and 1 cent to 7 dollars and 50 cents and has a height of 5. As 1 dollar has 100 cents hence 50 cent will be equal to the 0.50 dollar. Thus the range of bar 3 is 0.01 to 7.5 dollar.

The range of bar 4 is 7 dollars and 51 cents to 10 dollars and has a height of 1. As 1 dollar has 100 cents hence 50 cent will be equal to the 0.50 dollar. Thus the range of bar 4 is 7.51 to 10 dollar.

In all the four bars the value of dollar fall between the range of 0 dollar to the 10 dollar. This condition satisfy only by the option C.

Hence, The option C is the correct option which is,

{0.75, 2.50, 7.50,7.50,7.50,7.50,10.00}

Answer:

In this equation, y = 2x - 5, it is already in that form and so the cumber in front of the x is the slope (2) and the constant number is the y-intercept (-5) - it's negative because of the minus sign in front of the number. So, the slope is 2 and the y-intercept is -5.

Answer:

100°

Step-by-step explanation:

A triangle is a polygon shape with three sides. Triangles are of different types such as obtuse, scalene, equilateral, isosceles etc.

In triangle ABC:

70° + 50° + ∠C = 180° (sum of angles in a triangle)

120 + ∠C = 180

∠C = 180 - 120

∠C = 60°

Since ∠C is bisected into ∠ACD and ∠BCD, hence:

∠ACD = ∠BCD = ∠C / 2

∠ACD = ∠BCD = 60 / 2

∠ACD = ∠BCD = 30°

In triangle ACD:

∠A + ∠ACD + ∠ADC = 180° (sum of angles in a triangle)

50 + 30 + ∠ADC = 180

∠ADC + 80 = 180

∠ADC = 100°

Final Answer: [tex]f = \frac{ax}{2} + \frac{3b}{2}[/tex]

Steps/Reasons/Explanation:

We will be trying to rewrite the equation. To do this we will move [tex]2f[/tex] to the left. Then, we will move [tex]ax + 3b[/tex] to the right.

Question: Solve for [tex]f[/tex]: [tex]ax + 3b = 2f[/tex].

Step 1: Rewrite the equation.

[tex]2f = ax + 3b[/tex]

Step 2: Divide each term by [tex]2[/tex] and simplify.

[tex]\frac{2f}{2} = \frac{ax}{2} + \frac{3b}{2}[/tex]

Step 3: Cancel out the common factor of [tex]2[/tex].

[tex]\frac{Cancel 2 f}{Cancel 2} = \frac{ax}{2} + \frac{3b}{2}[/tex]

Step 4: Divide [tex]f[/tex] by [tex]1[/tex].

[tex]f = \frac{ax}{2} + \frac{3b}{2}[/tex]
