Which of the following expressions are equivalent to -8 -(-1)-5

Answer:4

Step-by-step explanation:What +7=11 bause the () make a multiplication and 11x3=33

Answer:

n=4

Step-by-step explanation:

3(n+7)=33

Lets mulitply..

3n+21=33

Then we need 3n alone...

To do this subract 21 from 33 and you get 12.

3n=12

Divide 3n by 3 and 12 by 3.

n=4

To find the difference, first calculate how much 3 pounds of each meat costs.

$3.20 × 3 = $9.60 for 3 pounds of chicken

$4.59 × 3 = $13.77 for 3 pounds of beef

Now, take the difference.

$13.77 - $9.60 = $4.17

3 pounds of beef costs $4.17 more than 3 pounds of chicken.

Answer:

3 pounds of beef costs $4.17 more than 3 pounds of chicken

65 - 11 = 54

Final answer:

The center of the circle is (3, -4) and the radius is approximately 5.66 units.

Explanation:

To find the center and radius of the given circle, we need to rewrite the equation in the standard form of the equation of a circle. The standard form is: (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius.

So, let's complete the square for both x and y terms in the given equation:

(x^2 - 6x) + (y^2 + 8y) = 7

(x^2 - 6x + 9) + (y^2 + 8y + 16) = 7 + 9 + 16

(x - 3)^2 + (y + 4)^2 = 32

Now we can see that the center of the circle is (3, -4) and the radius is √32 or approximately 5.66 units.

Answer:

$13,952.30

Step-by-step explanation:

refer to attached graphic

the formula for compound interest is given as

A = P [ 1 + (r/n) ] ^ (nt)

where

A = final amount (we are asked to find)

P = principal amount = $13,500

r = rate = 3.3% = 0.033

n = 12 (compounded monthly)

t = 1 year

substituting these values into the equation

A = 13500 [ 1 + (0.033/12) ] ^ [(12)(1)]

A = 13500 [ 1 + 0.00275 ] ^ 12

A = 13500 [1.00275 ] ^ 12

A = 13500 (1.0335)

A = $13,952.30

The balance on a $13,500 deposit earning 3.3% and compound monthly after 1 year is equal to $13,952.30.

In Mathematics and Financial accounting, compound interest can be calculated by using the following mathematical equation (formula):

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

Where:

By substituting the given parameters into the formula for compound interest, we have the following;

[tex]A(1) = 13500(1 + \frac{0.033}{12})^{12 \times 1}\\\\A(1) = 13500(1.00275)^{12}[/tex]

Future value, A(1) = $13,952.30.

Answer:Type of Angle Description

Acute Angle is less than 90°

Right Angle is 90° exactly

Obtuse Angle is greater than 90° but less than 180°

Straight Angle is 180° exactly

Step-by-step explanation:

Answer:

∠ABC = 62°, ∠DBE = 62°, ∠CBE = 118°, ∠ABD = 118°

Step-by-step explanation:

We can say that angle ABC and angle DBE are vertically opposite angles because there are only two intersecting lines. Vertically opposite angles are equal so we can form an equation:

4x + 2 = 5x - 13

5x - 4x = 2 + 13

x = 15

Now we can substitute x into the equation and find out the value for angles ABC and DBE.

4(15) + 2 = 60 + 2 = 62°, just to make sure we need to substitute x into the other equation to see whether we get the same answer:

5(15) - 13 = 75 - 13 = 62°, now we can confirm that angles ABC and DBE are 62°.

Now we can use the rule, angles on a straight line add up to 180°, to find the other two angles, because these two angles are vertically opposite, they are also equal to each other.

180 - 62 = 118°

Angles CBE and ABD are both 118°

Answer:

- 7y²

Step-by-step explanation:

(0,01)⁻¹/² × ∛(- 343y⁶/1000) =

= -(1/100)⁻¹/² × ∛( - 7³y⁶/10³)

= - 100¹/² × 7y²/10

= -(10²)¹/² × 7y²/10

= - 10 × 7y²/10

= - 7y²

Answer:

-7y^2

Step-by-step explanation:

(0.01)^(-1/2) = (1/0.01)^(1/2) = 100^(1/2) = 10

(-343 × y^6 ÷ 1000)^(1/3) =

(-343)^(1/3) × (y^6)^(1/3) ÷ 1000^(1/3)

= -7 × y^2 ÷ 10 = -0.7y^2

10 × -0.7y^2

-7y^2

The slope is the price of a ticket = 95

The y intercept is the service fee = 11

The equation would be multiplying the price of a ticket (slope) by the number of tickets being purchased (x) and then add the service fee ( y intercept)

Equation: f(x) = 95x + 11

Answer:

The slope is the price of a ticket = 95

The y intercept is the service fee = 11

The equation would be multiplying the price of a ticket (slope) by the number of tickets being purchased (x) and then add the service fee ( y intercept)

Equation: f(x) = 95x + 11

8y² + 6y + 1 = (4y + 1)(2y + 1)

Option A:

Lateral surface area = 1319 cm²

Solution:

Given image is the cone.

Radius of the cone = 15 cm

Slant height = 28 cm

Value of π = 3.14

To find the lateral surface area of the cone:

Lateral surface area = [tex]\pi r l[/tex]

                                 [tex]=3.14\times 15\times28[/tex]

                                 =  1318.8 cm²

Change this to nearest whole unit.

Lateral surface area = 1319 cm²

Hence the lateral surface area of the cone is 1319 cm².

Option A is the correct answer.

Answer:1/4

Step-by-step explanation:

Answer:

1) one solution

2) Infinitely many solution

3) no solution

Step-by-step explanation:

The first equation is -14-8x=-2(-3x+7)

Let us expand the right hand side to get:

-14-8x=-2*-3x+-2*7

We multiply -14-8x=6x-14

We group similar terms to get:

-8x-6x=-14+14

Combine similar terms to get:

-14x=0

Divide through by -14 to get:

x=0

2) The second equation is 3+5x=5(x+2)-7

We expand to obtain:

3+5x=5x+5*2-7

Multiply to get:

3+5x=5x+10-7

This gives us

3+5x=5x+3

5x=5x

1=1

There is infinitely many solutions

3) The third equation is: 36-7x=-7(x-5)

We expand to get:

36-7x=-7x+35

Group similar terms;

-7x+7x=35-36

0=-1

The given figure is missing so I attached it below

m∠ A B C = 72°

m∠ F B C = 108°

m∠ A B D = 90°

m∠ D B E = 18°

Step-by-step explanation:

∵ Lines A F and C E are intersected at point B

∴ ∠ A B C and ∠ F B E are vertical opposite angles

- That mean they are equal in measures

∴ m∠ A B C = m∠ F B E

∵ m∠ F B E = 72°

∴ m∠ A B C = 72°

∵ Ray F B and line E C are intersected at B

∴ ∠ C B F and ∠ F B E formed a pair of linear angles

- Their measures is 180°

∴ m∠ C B F + m∠ F B E = 180°

∵ m∠ F B E = 72°

∴ m∠ C B F + 72 = 180

- Subtract 72 from both sides

∴ m∠ C B F = 108°

∵ Ray B D ⊥ to line A F

- That mean ∠ A B D and ∠ F B D are formed a pair of linear

  angles equal in measures, then their measures is 180 ÷ 2 = 90

∴ m∠ A B D = m∠ F B D = 90°

∴ m∠ A B D = 90°

∵ Ray B E divides ∠ D B F into two angles D B E and F B E

∵ m∠ F B D = 90°

∴ m∠ D B E + m∠ F B E = 90°

∵ m∠ F B E = 72°

∴ m∠ D B E + 72 = 90°

- Subtract 72 from both sides

∴ m∠ D B E = 18°

The answer is 20000000000029

Step-by-step explanation:

Let O represents older brother

M represents middle brother

& Y represents younger brother.

Therefore, according to the given condition:

[tex] \frac{3}{4} y = \frac{2}{3} m = \frac{1}{2} o \\ \\ \therefore \: \frac{3}{4} y = \frac{2}{3} m \\ \implies \: m = \frac{3}{2} \times \frac{3}{4} y = \frac{9}{8} y \\ \\ next \: \: \frac{3}{4} y = \frac{1}{2} o \\ \implies \: o = \frac{2}{1} \times \frac{3}{4} y = \frac{3}{2} y \\ \\ \because \: o + m + y = 58 \\ \\ \therefore \: \frac{3}{2} y + \frac{9}{8} y + y = 58 \\ \\ \therefore \: \frac{12}{8} y + \frac{9}{8} y + \frac{8}{8} y = 58 \\ \\ \therefore \: \frac{29}{8} y = 58 \\ \\ \therefore \: y = 58 \times \frac{8}{29} \\ \\ \therefore \: y = 2 \times 8 \\ \\ \therefore \: y = 16 \: years[/tex]

Answer:

18.75 Kg : 11.25 Kg

Step-by-step explanation:

Sum the parts of the ratio, 5 + 3 = 8 parts

Divide 30 Kg by 8 to find the value of one part of the ratio

30 Kg ÷ 8 = 3.75 Kg ← value of 1 part of the ratio, thus

5 parts = 5 × 3.75 Kg = 18.75 Kg

3 parts = 3 × 3.75 Kg = 11.25 Kg

Answer:i think it is 0

Step-by-step explanation:

You can use the fact that if (x-root) is a factor of a single variable polynomial function p(x) = 0

A binomial factor of p(x) is (x-2)

Let its root be x = k

Then we have one of the factor of polynomial as (x-k)

Root of a polynomial function p(x) is a value of x such that putting that value in place of x makes the output 0.

Thus, if x = k is a root of the polynomial p(x), then

p(k) = 0

Since it is given that

p(2) + 4=4

thus,

p(2) = 4-4 = 0

Thus, x = 2 is a root of the polynomial function, and thus, using the aforesaid conclusions, we have (x-2) as one of the factors of the considered polynomial function.

Thus,

A binomial factor of p(x) is (x-2)
