Answer:

The slope is 5

Step-by-step explanation:

To find the slope we use the equation (y2-y1)÷(x2-x1). x is the first number in each equation and y is the second so this equation would be (10-5)÷(1-0). Which is 5÷1 which equals 5. Thefore the slope is 5

In this truss bridge, AAOB ABDC. AO=5 meters, BD=10 meters, AB=5 meters. What is the length of BC? A. 5 m B. 8 m C. 10 m D. 15 m

Olenka [21]

Consider $\Delta AOB\cong \Delta BDC$ .

Given:

$\Delta AOB\cong \Delta BDC, AO=5\ m,BD=10\ m, AB=5\ m.$

To find:

The length of BC.

Solution:

We have,

$\Delta AOB\cong \Delta BDC$

We know that the corresponding parts of congruent triangles are congruent (CPCTC).

$AB=BC$ (CPCTC)

$5\ m=BC$

The length of BC is 5 m. Therefore, the correct option is A.

Elza [17]

Answer:

Total length of string required in yards $8112$ yards

Step-by-step explanation:

The length of the string attached with each balloon is equal to $12$ feet

In the party total number of balloon used is equal to $52$ balloons

The total length of the string required

Length of string used in one balloon * total number of balloons

$= 12 * 52 = 624$ feet

1 feet is equal to 13 yards

Total length of string required in yards $13 * 624 = 8112$ yards

Solve each exponential equation by using properties of common logarithms. When necessary, round answers to the nearest hundredth

lisabon 2012 [21]

Answer:

0.08

Step-by-step explanation:

Please use parentheses to indicate which operations must be done first. I 'm choosing to believe that you meant 7^(3x-1) and 5^(x-1).

Taking the common log of both sides, we get:

(3x-1)log 7 = (x-1)log 5

Then 3x·log 7 - log 7 = x log 5 - log 5

Grouping the x terms:

x(3·log 7 - log 5) = log 7 - log 5. We combine log 7 and log 5, obtaining log (7/5).

Then x(3·log 7 - log 5) = log (7/5).

Solving for x:

log (7/5)

x = ---------------------

3·log 7 - log 5

0.1461

x = ------------- = 0.08

1.0363

This agrees with the 3rd answer choice.
