Answer:

[tex]1\frac{3}{8}[/tex] hours, or 1 hour and 22.5 minutes

Step-by-step explanation:

Wanda spends a third of her [tex]4\frac{1}{8}[/tex] hours studying math. Let us multiply these two fractions to find how much time she spent. Our first step would be to convert the mixed number into an improper fraction, as mixed numbers are hard to manipulate with:

[tex]4\frac{1}{8} =\\\frac{33}{8}[/tex]

Now let us multiply:

[tex]\frac{1}{3} *\frac{33}{8} =\\\frac{11}{8}[/tex]

If we wish, we can convert this into a mixed number:

[tex]\frac{11}{8}= \\1\frac{3}{8}[/tex]

or, 1 hour and 22.5 minutes.

Therefore, Wanda spent [tex]1\frac{3}{8}[/tex] hours, or 1 hour and 22.5 minutes studying math.

I hope this helps! Let me know if you have any questions :)

Answer:

x=10

Step-by-step explanation:

First off those are not triangles, tell someone that if you can and it hasn't been said already. Since 6 and 9 correspond we know the big triangle is 1.5 times the size of the small one. Because of this, we can set 1.5(2x-10) or 3x -15 = 15. x = 10. You can also just take 15/1.5 to get 10 but the stuff above is the work.

Answer:

x = 10

Step-by-step explanation:

since the two shapes are similar , setting them up in proportion can help to find x, like this ;

2x - 10 / 15 = 6 / 9......cross multiply

9 × ( 2x - 10 ) = 6 × 15

18x - 90 = 90

18x = 90 + 90

18x = 180

x = 10

Answer:

VX=50

Step-by-step explanation:

VX=[tex]\frac{1}{2} *UT[/tex] (The straight line joining the mid points of two sides of a triangle is parallel to the third side and equal to half of it.

[tex]z-41=\frac{1}{2} *z+9[/tex]

[tex]z-41=z+9/2[/tex]

do cross multiplication

2(z-41)=z+9

2z-82=z+9

2z-z=9+82

z=91

VX=z-41

=91-41

Answer:

x = 5

Step-by-step explanation:

You need to find de value of x.

4x - 1 = 18

4x = 18 + 1

4x = 19

x = 19/4

x = 4,75 but, the questions says:  smallest integer value, so, the smallest is the integer number more near of 4,75, which is 5.

testing:

x = 5

4*5 - 1 > 18

20 -1 > 18

19 > 18 TRUE

x = 4

4*4 - 1 > 18

16 - 1 > 18

15 > 18 FALSE

Answer:

2b-10≤27

Step-by-step explanation:

In this problem, we use b to represent the unkown number. Please be careful of order of operations when writing the inequality. (The difference of a number and 5) multiplied by 2 is at most 27. Also, note that the both sides of the inequality can be 27, but no more than 27.

[tex]2(b-5)\leq 27\\2b-10\leq 27\\[/tex]

If you wish to solve for b from here, simply isolate the term containing b and solve from there.

I hope this helps! Let me know if you have any questions :)

Answer:

2(x - 5) < 27

Step-by-step explanation:

Equation

2(b - 5)<27

Explanation

Break this down

difference means subtract.

The number is b

and finally for now, the difference between a number and 5 is

x - 5

Twice that difference is

2(x - 5)

And the keyword less (than) 27. Always make sure you know what less than means. It means that it is never equal to 27, but it can be pretty close.

26.999999999999 < 27

So the final result is

2(x - 5) < 27

Answer:

Step-by-step explanation:

Perimeter

The perimeter is the total length of all the sides. The length of the horizontal sides is 8 ft + 10 ft = 18 ft. The length of the slant sides can be found using the Pythagorean theorem. For side length s, we have ...

  s^2 = 8^2 + 16^2

  s^2 = 64 +256 = 320

  s = √320 = 8√5

Then the perimeter is ...

  P = 2(8√5 + 18) = 36 +16√5 ≈ 71.777 . . . feet

__

Area

The area is given by the formula ...

  A = bh

where b is the base and h is the height.

  A = (18 ft)(16 ft) = 288 ft²

Answer:

a₂₅ = - 367

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = - 22 - (- 7) = - 37 - (- 22) = - 15

This indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 7 and d = - 15 , then

a₂₅ = - 7 + (24 × - 15) = - 7 - 360 = - 367

Change to a decimal

.833333

Multiply by 100

83.33333%

.33333 repeating is 1/3

83 1/3 %

Answer:

[tex]83.33\%[/tex]

Step-by-step explanation:

Number of kittens in the litter = 6

Number of Black kittens = 5

Number of Brown Kittens = 1

Now let's find the percentage of black kittens

[tex] = \frac{number \: \: of \: \: black \: \: kittens}{number \: \: of \: \: total \: \: kittens} \times 100\% \\ = \frac{5}{6} \times 100\% \\ \\ = \frac{500}{6} \times 100\% \\ = 83.33\%[/tex]

Answer:

The volume is 60 cubic units

Step-by-step explanation:

It is given that Savannah is using the unit cubes for determining the volume of her desk drawer.

Each of the cube have dimensions of 1 unit by 1 unit by 1 unit

The base of the drawer is 4 unit cubes by 3 units cubes. And the height of the desk drawer is 5 units cube.

Thus the volume of her desk drawer is = 4 x 3 x 5

                                                                = 60 cubic units

Step-by-step explanation:

Answer:

Point T is the right angle of the triangle, so RTS = 90 degrees

8x + 18 = 90 (degrees)

8x = 72

x = 9 degrees

Step-by-step explanation:

If  [tex]\angle RTS = 8x + 18[/tex] and line [tex]TR[/tex] is perpendicular to line [tex]TS[/tex], then  [tex]x[/tex]  will be [tex]9^0[/tex].

A line is said to be perpendicular to another line if the two lines intersect at a right angle i.e. make [tex]90^0[/tex] angle with that line.

We have,

[tex]\triangle RTS[/tex] in which,

[tex]\angle RTS=8x+18[/tex]

Also it is mentioned that [tex]TR \perp TS[/tex] i.e.

[tex]\angle RTS=90^0[/tex]

So, compare values of [tex]\angle RTS[/tex],

We get,

[tex]8x+18=90[/tex]

[tex]8x=72[/tex]

[tex]x=9^0[/tex]

Hence, we can say that If  [tex]\angle RTS = 8x + 18[/tex] and line [tex]TR[/tex] is perpendicular to line [tex]TS[/tex], then  [tex]x[/tex]  will be [tex]9^0[/tex].
