Answer:

17.5 acres

Step-by-step explanation:

Let the areas of A, B, and C be 2x, 3x, and 5x, respectively,

then 2x = 3.5 acrea, x = 3.5/2 acres

Total area is 2x + 3x + 5x = 10x = 10 * 3.5/2 = 17.5 acres

It takes them 12 hours to design a total of 7 logos if they both start working at the same time

This is the amount per unit time.

Since one graphic designer takes 3 hours to design a logo. Her less experienced colleague takes 4 hours to design a logo, we need to find the rate at which the work is done.

Now, since we require the time to desigh 7 logos, this time is T = number of logos/combined rate

= 7 logos ÷ 7/12 logo/hr

= 12 hr

So, it takes them 12 hours to design a total of 7 logos if they both start working at the same time

Answer:

The angle of x is 83°

Step-by-step explanation:

A straight line has a total of 180°. That means if you can figure out what the third angle on the bottom is (the one in the middle) you can add 41 to it and subtract that from 180. Since all the lines are straight you can say that the middle angle on the bottom is the same as the middle angle on the top. So:

180° - (41° + 56°) = 83°

Answer:

2 < AB < 18

Step-by-step explanation:

Answer:

The range is from [tex]18[/tex] to [tex]2[/tex] (greatest to least)

[tex]2 < x < 18[/tex]

Step-by-step explanation:

we know that

The triangle inequality theorem, states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side

Let

x-----> the length of the third side AB of triangle ABC

Applying the triangle inequality theorem

case A)

[tex]8+10 > x[/tex]

[tex]18 > x[/tex]

Rewrite

[tex]x < 18[/tex]

case B)  

[tex]8+x > 10[/tex]

[tex]x > 10-8[/tex]

[tex]x > 2[/tex]

The solution for the range of possible side lengths of the third side is the interval

[tex](2,18)[/tex]

so

[tex]2 < x < 18[/tex]

All real numbers greater than [tex]2[/tex] and less than [tex]18[/tex]

The number [tex]2[/tex] and the number [tex]18[/tex] are not included in the solution

The value of the angles between the altitudes dropped from the vertices A and C equals [tex]180^{\circ} - \alpha[/tex].

In this question we must apply definitions and theorems of Euclidean geometry to derive the value of all required angles.

Based on geometry we know that heights are perpendicular to sides opposite to an angle, sum of internal triangles equals 180°, sum of supplementary angles equals 180°.

Answer: B

Step-by-step explanation:

This is a vertical line, meaning it fails the vertical line test, and thus cannot be a function.

Answer:

Lori reportedly paid her mother a third of the $39. Now let's see what 1/3 of $39 is.

$13 = 39/1 x 1/3 So she paid $13, but she still owes $23 of the original $39.

So, we need to figure out what 2/3 is, and here's how: 39 - 13 = $26. She owes her mother $26.

As a result, it now indicates that she paid 1/4 of the outstanding debt. Let's see what 1/4 of $26 equals.

6.50 = 26/1 x 1/4 She repaid $6.50 of the $26 she had borrowed. And she still owes 3/4 of what she owes. Let's find out what 3/4 means now. So, remove $6.50 from $26, as follows: 26 - 6.50= $19.50.

Step-by-step explanation: See above.

Answer:

7.08

Step-by-step explanation:

39 divide by 1/3 =117

117 divide by 1/4= 708

and u get 7.08

The cost of 1 apple and 5 mangoes is $6.15.

Let's look at how to form and solve simultaneous equations in a word problem.

Assuming that the cost of each apple and mango is equal in both packs.

Let the cost of an apple be a and that of a mango be m.

10a +5m= 12 -----(1)

15a +4m= 14.15 -----(2)

Steps for solving equations with two variables

Working

Here, I am making the value of the coefficient of m constant.

(1) ×4:

40a +20m= 48 ----(3)

(2) ×5:

75a +20m= 70.75 -----(4)

Moving on to step 2, we can eliminate the m term by subtracting equation (3) from (4). When the sign of the terms are equal, we use subtraction to eliminate the term. On the other hand, if one of the sign is positive and the other is negative, adding the two equations together will eliminate the term (provided that you have already ensured that the magnitude of the coefficient is equal).

(4) -(3):

75a +20m -(40a +20m)= 70.75 -48

Expand:

75a +20m -40a -20m= 22.75

Simplify:

35a= 22.75

Let's continue with step 3, where we solve for a.

a= 22.75 ÷35

a= 0.65

The cost of an apple is $0.65.

Now, moving on to step 4!

Substitute a= 0.65 into (1):

10(0.65) +5m= 12

6.5 +5m= 12

5m= 12 -6.5

5m= 5.50

5 mangoes costs $5.50.

Cost of 1 apple and 5 mangoes

= $0.65 +$5.50

= $6.15

Thus, the cost of 1 apple and 5 mangoes is $6.15.

Answer: 64

Step-by-step explanation:

Answer:

1560

Step-by-step explanation:

First (2 1/2)/(1/4) = (5/2)(4) = 20/2 = 10

Next, 3/(1/4) = 3(4) = 12

Lastly, (3 1/4)/(1/4) = (13/4) x 4 = 52/4 = 13

This means we need 10 rows of 12, 13 high. 10(12)(13) = 1560 cubes.

Another way is to multiply 2 1/2 x 3 x 3 1/4 = 5/2 x 3 x 13/4 = 195/8

A 1/4 inch cube is 1/4 x 1/4 x 1/4 for a volume of 1/64

(195/8)/(1/64) = (195/8)(64) = 1560 cubes.

Answer:

40° and 100°

Step-by-step explanation:

An obtuse triangle has one obtuse angle, or an angle that measures more than 90° but less than 180°. Options 1 and 2 are not correct, because these are acute angles.

So, one of the angles must be 40°, and the other may be 100° or 120°.

The measures of the angles in a triangle add up to 180°

40° + 40° + [tex]x[/tex] = 180°

80° + [tex]x[/tex] = 180°

[tex]x[/tex] = 180° - 80°

[tex]x[/tex] = 100°

The other two angles are 40° and 100°.

Step-by-step explanation:

Step 1- convert 25% into a decimal

Step 2- Multiply 34,400.00 x 0.25

            Which should give you $8600.00

Step 3- Then subtract 34,400.00 from 8600.00
