Answer:

B) 42 Degrees

Step-by-step explanation:

An angle bisector is basically a line that splits an angle into two congruent angles.

In this case, the large angle ABC is bisected by ray BD.

Angle ABC is given to be 84 degrees, so the measure of angle ABD is exactly half of that, or 42 degrees.

Let me know if this helps!

C

Step-by-step explanation:

Here, we want to select the option that present a function

For a set of points to be a function, we have that every single x value is directly mapped to a single y value

As we can see, this is correct only for the third option

There is no repetition of x-values or y-values

Every x value is directly linked to a different y-values

Answer:

75 cents per can

Step-by-step explanation:

8 for $6 = 75 cents per can

10 for $10 = $1 per can

2 for $3 = $1.50 per can

The last store sold 28-oz for $1.40 each

To obtain the cost per 15-oz can of baked beans

28-oz / 15-oz = 1.86667of 15 - oz cans of baked beans can be obtained from 28 - oz.

The price per can will now be :

$1.40 / 1.8666666

= $0.75

= 0.75 * 100 = 75 cents

Hence, for the last store, they sold at 75 cents per can similar to the first store.

Answer:

x = 5, x = 2

Step-by-step explanation:

y=x²-7x+7 but also y=-3

so x²-7x+7=-3

x²-7x+10=0

when factorising think about 2 numbers you multiply by each other tp give 10 but at the same time their sum is 7

-5x-2=10

-5+-2=-7

so (x-5)(x-2)=0

(note: multiply the two brackets to check if ur answer is correct and that it gives x²-7x+10=0)

x-5=0 so x=5

but also x-2=0 so x=2

Answer:

x = 26°

Step-by-step explanation:

Let us solve the question

In the given figure

∵ The ray NC bisects ∠WNB

→ That means it divides the angle into two equal angles, ∠WNC and ∠CNB.

∴ m∠WNC = m∠CNB

∵ m∠WNC = 3v - 4

∵ m∠CNB = 2v + 6

→ Equate the measures of the two angles

∴ 3v - 4 = 2v + 6

→ Add 4 to both sides

∵ 3v - 4 + 4 = 2v + 6 + 4

∴ 3v = 2v + 10

→ Subtract 2v from both sides

∵ 3v - 2v = 2v - 2v + 10

∴ v = 10

∵ x = m∠WNC

∴ x = 3v - 4

→ Substitute v by 10

∵ x = 3(10) - 4

∴ x = 30 - 4

∴ x = 26°

Step-by-step explanation:

Answer:

The x-coordinate of the intersection point (x, y) = (-0.5, -1) of the system is: -0.5

Hence, option A) i.e. -0.5 is correct.

Step-by-step explanation:

Given the system of equations

2.4x - 1.5y = 0.3

1.6x + 0.5y = -1.3

solving the system of equations

[tex]\begin{bmatrix}2.4x-1.5y=0.3\\ 1.6x+0.5y=-1.3\end{bmatrix}[/tex]

Multiply 2.4x - 1.5y = 0.3 by 2

Multiply 1.6x + 0.5y = -1.3 by 3

so the system of equations becomes

[tex]\begin{bmatrix}4.8x-3y=0.6\\ 4.8x+1.5y=-3.9\end{bmatrix}[/tex]

so

[tex]4.8x+1.5y=-3.9[/tex]

[tex]-[/tex]

[tex]\underline{4.8x-3y=0.6}[/tex]

[tex]4.5y=-4.5[/tex]

so the system of equations becomes

[tex]\begin{bmatrix}4.8x-3y=0.6\\ 4.5y=-4.5\end{bmatrix}[/tex]

solve 4.5y = -4.5 for y

[tex]4.5y=-4.5[/tex]

Multiply both sides by 10

[tex]4.5y\cdot \:10=-4.5\cdot \:10[/tex]

Refine

[tex]45y=-45[/tex]

Divide both sides by 45

[tex]\frac{45y}{45}=\frac{-45}{45}[/tex]

Simplify

[tex]y=-1[/tex]

For 4.8x - 3y = 0.6, plug in y = -1

[tex]4.8x-3\left(-1\right)=0.6[/tex]

[tex]4.8x+3\cdot \:1=0.6[/tex]

[tex]4.8x+3=0.6[/tex]

Multiply both sides by 10

[tex]4.8x\cdot \:10+3\cdot \:10=0.6\cdot \:10[/tex]

Refine

[tex]48x+30=6[/tex]

Subtract 30 from both sides

[tex]48x+30-30=6-30[/tex]

Simplify

[tex]48x=-24[/tex]

Divide both sides by 48

[tex]\frac{48x}{48}=\frac{-24}{48}[/tex]

simplify

[tex]x=-\frac{1}{2}[/tex]

or

[tex]x = -0.5[/tex]

Thus,

(x, y) = (-0.5, -1)

Therefore, the x-coordinate of the intersection point (x, y) = (-0.5, -1) of the system is: -0.5

Hence, option A) i.e. -0.5 is correct.

Step-by-step explanation:

area of square is a^2

3.1yd^2=9.61yd^2

Answer:

Area = 9.61^2

Step-by-step explanation:

A square has all equal sides so each side is the same length. To find the area mulyiply the length by the width. Since it is a square both sides will be 3.1 yds long. So multiply 3.1 by 3.1 and you will get 9.61^2, That is the area of the square.

Answer:

monthly payment =  $56.445

Step-by-step explanation:

given data

loan = $5000

interest rate r = 5.3 % = 0.053

time  t = 2 year = 24 months

solution

we will use here amount of the monthly payments formula that is

monthly payment = principal × [tex]\frac{r}{1+(1-r)^{-t}}[/tex]      ................1

put here value and we get

monthly payment = 5000 × [tex]\frac{0.053}{1+(1-0.053)^{-24}}\\[/tex]

monthly payment =  $56.445

The temperature is [tex]50^{\circ}F[/tex]

Step-by-step explanation:

Given

[tex]F= (C*1.8) + 32[/tex]

Required

Find F when [tex]C = 10[/tex]

[tex]F= (C*1.8) + 32[/tex]

Substitute 10 for C

[tex]F = 10 * 1.8 + 32[/tex]

[tex]F = 18 + 32[/tex]

[tex]F = 50[/tex]

Answer:

m∠BCD = 24°

Step-by-step explanation:

By the theorem,

"Angle subtended by an arc at the center of the circle is twice in measure of the angle subtended at the circumference."

m(∠BOD) = 2(m∠BFD)

                = 2(78°)

                 = 156°

Therefore, m(arc BD) = m∠BOD = 156°

Since, m(arc BD) + m(arc BFD) = 360°

156° + m(arc BFD) = 360°

m(arc BFD) = 360 - 156

                   = 204°

Since, "angle formed outside the circle by the intersection of two tangents measure half of the difference of the intercepted arcs".

m∠BCD = [tex]\frac{1}{2}[m(\text{arc BFD})-m(\text{arc BD})][/tex]

              = [tex]\frac{1}{2}[204 - 156][/tex]

              = 24°

Answer:

480 seconds per day

Step-by-step explanation:

There are 24 hours in a day, 24*20=480 seconds per day

The number of seconds the given clock loses in a day is required.

The number of seconds lost by the clock in one day is 240 seconds.

The clock loses 20 seconds every hour.

A day has 24 hours.

If 20 seconds is lost every hour then the 20 seconds has to be added 24 times or the 20 has to be multiplied by 24.

So,

[tex]20\times 24=480\ \text{s}[/tex]
