Answer:

For question 2 (Triangle):

The triangle hThe entire triangle area = 2 * 13.125 =

26.25

Triangle perimeter both legs = 16.6 + base (7) = 23.6

For question 1 (Parallelogram):

longer congruent sides = 6-0 OR 4-(-2) = 6units

area= 3×6 = 18units^2

Q19. Four positive whole numbers add up to 36

MAXImum [283]

Answer:

Step-by-step explanation:

let the numbers be 7x,y,y,y.

7x+3y=36

3y=36-7x

$y=\frac{36-7x}{3} \\let~x=3\\y=\frac{36-7 \times 3}{3} =\frac{15}{3} =5\\$

numbers are 7×3,5,5,5

or 21,5,5,5

21×5×5×5=2625

Mario and Julio are working together to detail cars. When they work together, they can wash7 cars in 2 hours. If mario works alo

Morgarella [4.7K]

Answer: 6.56hours.

Step-by-step explanation:

Given;

Mario and julio can wash 7 cars in 2hours

While only mario can wash 5 cars in 3hours

Let m represent the rate at which mario work

j represent the rate at which julio work

t represent the rate at which mario and jolio combined work.

t = m + j

j = t -m .......1

t = 7 cars per 2hours = 7/2 = 3.5cars/hour

m = 5 cars per 3hours = 5/3 = 1.67cars/hour

From eqn 1

j = t -m = 3.5 - 1.67 = 1.83cars/hour

So, to determine the number of time it will take julio to detail 12 cars

Where = number of cars detailed

N = rate × time = j × time

time = N/j

time = 12/1.83

time = 6.56 hours

Therefore, it will take julio to detail 12 cars is 6.56 hours.

Find the angle measures. Justify your responses. Given: a||b, m1=71º Find m5, m8

Natalka [10]

Answer:

The measure of angle MNP is

m ∠ MNP = (x - y)/2

Explanation:

The image attached shows the figure corresponding to this question.

The angle MNP, which is also the angle LNP, is formed by the intersection of a secant and a tangent to a circle.

Then, you can use the theorem:

the angle formed by a secant and a tangent to a circle that intersect outside the circle is half the difference of the major arc minus the minor arc.

The major arc formed is identified with the letter x and the minor arc is identified with the letter y. Thus, the measure of the angle MNP is half the difference x - y:

m ∠ MNP = (x - y)/2
