Hello!

This is just a conceptual problem where you'll be converting units.

If her semitrailer is 3.5m high and the bottom of the bridge (how tall the support beam are) is 11ft 9in high, we'll need to convert them into the same units and then compare both values.

Let's convert from inches to meters.

Since there are 12 inches in a feet, we can convert 11 feet into 132 inches, meaning that the bottom of the bridge is at 141 inches.

In 1 meter, there is around 39.37 inches, so we'll be dividing 141 by 39.37, giving us a number of around 3.5814, meaning that the bottom of the bridge is higher than the height of the semitrailer, and her vehicle will fit under the bridge.

Hope this helps!

What is the approximate value of this logarithmic expression?
mestny [16]

Answer:

log_8{24} = 1.53

Step-by-step explanation:

Given

log_8{24}

Required

Solve:

Apply the following law of logarithm:

log_a{b} = \frac{log\ b}{log\ a}

So, we have:

log_8{24} = \frac{log\ 24}{log\ 8}

Using calculator, we have:

log_8{24} = \frac{1.38021124171}{0.90308998699}

log_8{24} = 1.52832083358

Approximate

log_8{24} = 1.53

Asap answer plssss!, John can do a piece of work in 6 days. When he and Marsha work together, it takes only 4 days. How long wil
BartSMP [9]

Answer:

12 days

Step-by-step explanation:

Let the amount of work be x.

John:

6 days = x

1 day = \frac{1}{6}x

Together:

4 days = x

1 day = \frac{1}{4}x

Marsha:

1 day = \frac{1}{4}x - \frac{1}{6}x

        = \frac{6}{24}x - \frac{4}{24}x

        = \frac{2}{24}x

        = \frac{1}{12}x

Marsha can do \frac{1}{12} of the work in 1 day.

No. of days taken (Marsha) = x ÷ \frac{1}{12}x

                                             = 12

Which is a possible number of real roots for a cubic function? Select all that apply.
poizon [28]
A cubic equation has degree 3. That means that the highest exponent of x (or whatever variable is being used) is 3. This means the function can have 0, 1, 2 or 3 roots.

Whatever the highest exponent of the variable is tells us the highest number of roots it can have. It can have that many or fewer but no less than 0.

Answer:

\overline{BC} \cong  \overline{DC} because corresponding parts of congruent triangles ΔACD and ΔACB are Congruent

Step-by-step explanation:

Statements,                                                Reason

\overline{AC} bisects ∠BCD,                                      Given        

\overline{DC} \perp  \overline{AD}                                                    Given

∠CDA ≅ ∠CBA                                           Right angles are ≅

\overline{AC} \cong  \overline{AC}                                                     Reflexive property

ΔACD ≅ ΔACB                                           Hypotenuse Leg (HL) congrurency

\overline{BC} \cong  \overline{DC}                                                    CPCTC

Where:

CPCTC = Corresponding parts of Congruent Triangles are Congruent

⊥ = Perpendicular to

≅ = Congruent

∠ = Angle

Δ = Triangle.
