Prove angle DBC= 45 degrees

Answer:

Step-by-step explanation:9

Answer:

slope = - 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, 5) and (x₂, y₂ ) = (4, 1)

m = [tex]\frac{1-5}{4-2}[/tex] = [tex]\frac{-4}{2}[/tex] = - 2

Answer:

Miranda made 9 visits to the store and Savannah made 7 visits to the store

Step-by-step explanation:

To find how many times Miranda and Savannah went to the store we would need to find the Greatest Common Multiple of the amount that each of them spends per visit. We do this by simply going through each of these numbers' times tables until we find a common one.

7 * 1 =  7                     9 * 1 = 9

7 * 2 =  14                   9 * 2 = 18

7 * 3 =  21                   9 * 3 = 27

7 * 4 =  28                  9 * 4 = 36

7 * 5 =  35                  9 * 5 = 45

7 * 6 =  42                  9 * 6 = 54

7 * 7 =  49                  9 * 7 = 63

7 * 8 =  56                  

7 * 9 =  63      

Finally, we can see that the first time that both Miranda and Savannah have spent the exact same amount would be when Miranda made 9 visits to the store and Savannah made 7 visits to the store. Each of which wasted $63

Answer: b. four fifths plus two fourths

Step-by-step explanation: Change the fractions to their equivalents in 20ths-- like finding the common denominator.

Divide the original denominator into 20, then multiply the result by the original numerator to get the new numerator.

4/5  20/5 = 4    4×4 = 16   so 4/5 is equivalent to 16/20

2/4   20/4 = 5    5×2 = 10   so  2/4 is equivalent to 10/20  

Add:    16/20 + 10/20 = 26/20

Answer:

The answer is option 2

Step-by-step explanation:

Working out above

Initial speed of the skateboard (u) = 0 m/s (Starts from rest)

Acceleration of the skateboard (a) = 2 m/s²

Time taken by the skateboard (t) = 2s

By using equation of motion, we get:

[tex] \bf \longrightarrow v = u + at \\ \\ \rm \longrightarrow v = 0 + 2 \times 2 \\ \\ \rm \longrightarrow v = 4 \: m {s}^{ - 1} [/tex]

[tex] \therefore [/tex] Final speed of the skateboard(v) = 4 m/s

Answer:

Please check the explanation!

Step-by-step explanation:

Given the equation

[tex]f\left(x\right)=-2|x+1|-1[/tex]

As some of the absolute rules are:

NOW, let us solve!

Let us substitute all the table values

Putting x = -4

[tex]y=-2\left|-4+1\right|-1[/tex]        ∵[tex]\mathrm{Apply\:absolute\:rule}:\quad \left|a\right|=a,\:a\ge 0[/tex]

[tex]y=-6-1[/tex]

[tex]y=-7[/tex]

So, when x = -4, then y = -7

Putting x = -3

[tex]y=-2|-3+1|-1\:[/tex]

[tex]y=-4-1[/tex]

[tex]y=-5[/tex]

when x = -3, then y = -5

Putting x = -2

[tex]y=-2\left|-2+1\right|-1[/tex]

[tex]y=-2-1[/tex]

[tex]y=-3[/tex]

when x = -2, then y = -3

Putting x = -1

[tex]y=-2\left|-1+1\right|-1[/tex]

[tex]y=-0-1[/tex]

[tex]y=-1[/tex]

when x = -1, then y = -1

Putting x = 0

[tex]y=-2\left|0+1\right|-1[/tex]

[tex]y=-2-1[/tex]

[tex]y=-3[/tex]

when x = 0, then y = -3

Putting x = 1

[tex]y=-2\left|1+1\right|-1[/tex]

[tex]y=-4-1[/tex]

[tex]y=-5[/tex]

when x = 1, then y = -5

I'm not 100% positive that my answer is remotley correct but I would say 25.

Step-by-step explanation:

and if that is you in your profile pic, you are very pretty.

I hope my answer helps!

Answer:

We can use a trick here. Let's look at the first few exponents of i to realize this:

i^0 = 1

i^1 = i

i^2= -1

i^3 = -i

i^4 = 1

i^5 = i

i^6 = -1

i^7 = -i

we can see that the pattern (1, i, -1, -i) repeats. Since 82/2 = 41, and 41 is only divisible by 1, i^41 = i, and i^2 = -1. -1*i = -i, so i^82 = -i.

Answer:

28 brownies - 4 scoops

x brownies - 5 scoops

Cross multiply and we get:

140 = 4x

Divide both sides by 4:

140/4 = 4x/4

35 = x

Hence, 5 scoops of flour will bake 35 brownies

Answer:

45

Step-by-step explanation:

Given :

Trina and Jessie went on a vacation to Hawaii. Trina went scuba diving and reached an elevation of −85.6 meters, which is below sea level.

Jessie went hang-gliding and reached an altitude of 87.9 meters, which is above sea level.

To Find :

The distance between them.

Solution :

Distance between them is :

[tex]D=87.9-(-85.6)\ m\\\\D = 173.5\ m[/tex]

Therefore, maximum distance between them is 173.5 m.

Hence, this is the required solution.

Answer:

0.1458 in decimal form.

Step-by-step explanation:

In mathematics, every integer is a rational number, hence a whole number 8 can be written as 8/1. 7/6 ÷ 8 = 7/48 in fraction form.

7/6 ÷ 8 = 0.1458 in decimal form.

Answer:

12 gallons of paint

Step-by-step explanation:

Sasha can paint 400 square feet using 1 gallon of paint

If she needs to paint 4,704 square feet, then she will need to purchase 4,704 / 400 = 11.76 gallons of paint. Since she can only purchase paint in whole gallons, she will need to purchase 12 gallons of paint (we have to round up).

Answer:

416

Step-by-step explanation:

Given that:

A previous random sample = 4000

Sample mean = 2250

[tex]\hat p = \dfrac{x}{n}[/tex]

[tex]\hat p = \dfrac{2250}{4000}[/tex]

[tex]\hat p = 0.5625[/tex]

The confidence interval level = 90%

Desired Margin of error E = 0.04

The level of significance at 90% C.I  = 1 - 0.90 = 0.10

The critical value [tex]Z_{\alpha/2} = Z_{0.10/2}[/tex]

[tex]\implies Z_{0.05} = 1.645[/tex]   ( From the  z tables)

[tex]n = \hat p \times (1- \hat p ) \bigg ( \dfrac{z_{0.05}}{E} \bigg)^2[/tex]

[tex]n = 0.5625 \times (1- 0.5625) \bigg ( \dfrac{1.645}{0.04} \bigg)^2[/tex]

[tex]n = 0.5625 \times (0.4375) \bigg ( 41.125 \bigg)^2[/tex]

n = 416.21

Thus, the number of citizens required to be sampled is [tex]\simeq[/tex] 416
