Hey guys please help ​

Mathematics
1 answer:
zimovet [89]3 years ago
6 0

Answer:

7.98 \:m

Step-by-step explanation:

Area of a triangle is base times height divided by 2.

A= \frac{bh}{2}

69.6= \frac{b \times 17.45}{2}

69.6 \times 2= b \times 17.45

139.2=b \times 17.45

\frac{17.45b}{17.45}=\frac{139.2}{17.45}

b=\frac{2784}{349}

b=7.97707

The appropriate unit is meters.

Isabel wrote this mystery problem. The quotient is multiple of 6. The dividend is multiple of 9. The divisor is a factor of 12.
Marina86 [1]

Answer:

Consider the expression q=\frac{a}{b}. q is called the quotient, a is is the dividend and b is the divisor.

Since q is a multiple of 6, then q has the form q=6k for some integer k.

Since a is a multiple of 9, then a has the form a=9s for some integer s.

Since b is a factor of 12, then if 12 can be expressed of the form 12=c*b, for c an integer. Then b has the form b=\frac{12}{m}

Replacing the preview expression in the initial expression we obtain:

6k=\frac{9s}{\frac{12}{m}}=\frac{9sm}{12}\\6*12k=9sm\\72k=9sm\\72k-9sm=0

Then 72k-9sm=0,\; for \; k,s,m\in \mathbb{Z} is a equation to Isabel's problem.

What is the relative size of (how many times as large) a circle's' circumference C to its diameter, d
Pavlova-9 [17]

Answer:

The circumference is pi times larger than the diameter of a circle.

Step-by-step explanation:

The formula of the circumference of a circle is

C = 2(pi)r = (pi)d

C = (pi)d

To find the ratio of the circumference to the diameter, divide both sides of the equation by d.

C/d = pi

The circumference is pi times larger than the diameter of a circle.
