Answer:

24 feet

Step-by-step explanation:

Given that,

Mrs. Booker had to run 8 yards to make it to a safe zone.

We need to convert this distance in feet.

The conversion from yards to feet is as follows :

1 yard = 3 feet

So,

8 yards = 24 feet

Hence, Mrs. Booker had to run 24 feet to make it to a safe zone.

Answer:

Is 6x and 4x+2 equivalent

? No!

Step-by-step explanation:

6x doesn't equal 4x+2

In order for them to be the same you would have to add the same terms example:

4x+2x would equal 6x

Extra explaining:

The only way for those term to be added would be if they had the same variable since only 4x has a variable the 2 cant be added. In math you CANNOT move your variables off of a number and add them back on after.

Answer:

x = 30

Step-by-step explanation:

AB  is a tangent to the circle so ∠ ABO = 90°

The sum of the 3 angles in a triangle = 180° , then

x + 2x + 90 = 180

3x + 90 = 180 ( subtract 90 from both sides )

3x = 90 ( divide both sides by 3 )

x = 30

Answer: x = 30

OA cuts the circle (O) at C

because ∠ABC is the  angle created by tangent rays and chord

=> ∠ABC = 1/2.∠AOB = 1/2.2x = x

ΔOBC has OB = OC (are both radii)

=> ΔOBC is the  isosceles triangle at O

=> ∠OCB = (180° - ∠COB)/2 = (180° - 2x)/2 = 90° - x

because ∠OCB is the outer angle of ΔABC

=> ∠OCB = ∠ABC + ∠CAB

⇔ 90° - x = x + x

⇔ 90 = 3x

⇔ x = 30

Answer:

za=24

Step-by-step explanation:

supplementary angles add up to equal 180

180=7x+x+30+6

step 1 combine like terms

180=8x+36

step 2 subtract 36 from each side

144=8x

step 3 divide each side by 8

x=18

now we just plug in 18 to x in x+6

18+6=24

Answer:

24°

Step-by-step explanation:

The sum of supplementary angles is 180°.

Thus, we can set up our equation as:

(x + 6) + (7x + 30) = 180

Combine like terms.

8x + 36 = 180

Isolate the variable by subtracting 36 from both sides.

8x = 144

Divide both sides by 8.

x = 18

Now, let's revisit the equation for m∠ZA, and plug in our x.

Answer:

$25,500

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 7%/100 = 0.07 per year,

then, solving our equation

I = 15000 × 0.07 × 10 = 10500

I = $ 10,500.00

The simple interest accumulated

on a principal of $ 15,000.00

at a rate of 7% per year

for 10 years is $ 10,500.00.

Answer:33

Step-by-step explanation:

Answer:

B. $352.80

Step-by-step explanation:

edge 2021

The principal on the loan with interest rate of 6% is $2000.

Given that a loan is given in the interest rate of 6%, interest received is $840 and the duration of the loan is 7 years,

We need to find the principal on the loan,

To find the principal on the loan, we can use the formula for simple interest:

Interest = Principal × Rate × Time

In this case, we know the interest is $840.00, the rate is 6%, and the time is 7 years.

Let's solve for the principal:

Principal = Interest / (Rate × Time)

Principal = $840.00 / (0.06 × 7)

Principal ≈ $840.00 / 0.42

Principal ≈ $2000.00

Therefore, the principal on the loan is $2000.00.

Answer:

Step-by-step explanation:

Given

[tex]A(t) = 30+8t-\frac{2}{3}(t+1)^{\frac{3}{2}}[/tex]

Required

Determine the maximum amount of water the tank can hold --- Missing from the question

Start by differentiating A w.r.t t

[tex]A'(t) = 0 + 8 + \frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}}][/tex]

Solving: [tex]\frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}}[/tex]

[tex]\frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}} = -\frac{2}{3}\frac{d}{dt}[(t+1)^{\frac{3}{2}}[/tex]

Apply power rule:

[tex]\frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}} = -\frac{2}{3}[\frac{3}{2}(t + 1)^{\frac{3}{2}-1} * \frac{d}{dt}[t+1][/tex]

[tex]\frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}} = -(t + 1)^{\frac{3}{2}-1} * \frac{d}{dt}[t+1][/tex]

[tex]\frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}} = -(t + 1)^{\frac{3}{2}-1} * [1+0][/tex]

[tex]\frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}} = -(t + 1)^{\frac{3}{2}-1} * [1][/tex]

[tex]\frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}} = -(t + 1)^{\frac{3}{2}-1}[/tex]

[tex]\frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}} = -(t + 1)^{\frac{1}{2}}[/tex]

So:

[tex]A'(t) = 0 + 8 + \frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}}][/tex]

A'(t) = 0 + 8 + \frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}}]

[tex]A'(t) = 0 +8 -(t + 1)^{\frac{1}{2}}[/tex]

[tex]A'(t) = 8 -(t + 1)^{\frac{1}{2}}[/tex]

Equate to 0 to solve for t

[tex]A'(t) = 0[/tex]

[tex]8 -(t + 1)^{\frac{1}{2}} = 0[/tex]

Collect Like Term

[tex]-(t + 1)^{\frac{1}{2}} = -8[/tex]

Square both sides

[tex](-(t + 1)^{\frac{1}{2}})^2 = (-8)^2[/tex]

[tex]t +1 = 64[/tex]

Make t the subject:

[tex]t = 64 - 1[/tex]

[tex]t = 63[/tex]

So, the tank is at maximum when t = 63.

Substitute 63 for t in: [tex]A(t) = 30+8t-\frac{2}{3}(t+1)^{\frac{3}{2}}[/tex]

[tex]A(63) = 30+8*63-\frac{2}{3}(63+1)^{\frac{3}{2}}[/tex]

[tex]A(63) = 30+8*63-\frac{2}{3}(64)^{\frac{3}{2}}[/tex]

[tex]A(63) = 30+8*63-\frac{2}{3}*512}[/tex]

[tex]A(63) = 30+8*63-\frac{2*512}{3}}[/tex]

[tex]A(63) = 30+8*63-\frac{1024}{3}}[/tex]

[tex]A(63) = 30+8*63-341.33[/tex]

[tex]A(63) = 192.67[/tex]

Approximate:

[tex]A(63) = 193[/tex]

Answer:

p = 2

Step-by-step explanation:

[tex]\frac{p}{18}[/tex] = [tex]\frac{8}{72}[/tex]

to work with smaller numbers you can look to reduce

for example, 8/72 can be reduced to 1/9

[tex]\frac{p}{18}[/tex] = [tex]\frac{1}{9}[/tex]

now you can cross-multiply:

9p = 18

p = 18/9 which is 2

Answer:

5

Step-by-step explanation:

(I'm assuming that by m2 and n2 you mean m to the power of 2 and n to the power of 2)

Whenever you have a number to a power, it is the same as that number times itself that power number of times. For example, 3 to the power of 4 is equal to 3 times itself 4 times, which is 3 * 3 * 3 * 3. If we use this and substitute the values in for m and n, we get that 3^2 - 2^2, and since 3^2 is 3 * 3 and 2^2 is 2 * 2 and 3 times 3 is 9 and 2 times 2 is 4, we get that 9 - 4 is 5.
