PLEASE HELP ME!!!!! take a look at the question please

timurjin [86]

according to clue no. 1 the number is 760 > x > 740. so, it could be any number between 740 - 760.

according to the 2 & 3 clue we can conclude that thousandths and ones digit are even and thousandth digit is twice the ones digit.

so the ones digit could be, 2 & 4 and the thousandth digit could be 4 & 8.

according to the 4th clue we can say that the tenths digit is 1 and thousandths digit is 4 as, thousandth digit is the 2nd even number after ones digit and also, sum of tenths and thousandth digit is 5 so, 1 + 4 = 5.

so, through this we can conclude that,

• ones digit = 2 as ( thousandth is twice the ones = 2 × 2 = 4 )

• tenths digit = 1 ( as 1 + 4 = 5 )

• thousandths digit = 4 ( as 4 + 1 = 5 )

according to clue no. 5 product of hundredths and hundreds is 7 so, 7 × 1 = 7.

so, according to this we can conclude that hundreds digit is 7 because in the required number the hundreds digit is itself 7

• hundreds digit = 7

• hundredths digit is = 1

and also, tens digit is 5 because only ones and thousandths digit are even.

so, the required number is, 752.114

hope this answer helps you dear & may u have a great day ahead!... take care!

What is the area of the figure, use 3.14 for π

xeze [42]

Answer: Area of a square is a².

4² = 16

Now find the area of the semicircle.

(πr²)/2

(3.14)(2)²/2

12.56/2

6.28

Now add the areas to find the total area.

6.28 + 16 = 22.28

Hope this helps :)

In QRS, mQ= 8x-17,mR=19x+4,and mS=5x+1. Classify QRS by its angles and sides

katen-ka-za [31]

Answer:

Option (3) and Option (5)

Step-by-step explanation:

By the property of a triangle,

Sum of interior angles of a triangle is 180°.

m∠Q + m∠R + m∠S = 180°

By substituting the measures of angles in the equation,

(8x - 17)° + (19x + 4)° + (5x + 1)° = 180°

32x - 12 = 180

32x = 192

x = 6

m∠Q = (8x - 17)° = 48 - 17

= 31°

m∠R = (19x + 4)° = 114 + 4

= 118°

m∠S = (5x + 1) = 30 + 1

= 31°

Since, one interior angle measures 118° which is grater than 90°.

Therefore, triangle QRS is an obtuse triangle.

Since, m∠Q = m∠R = 31°

It's an isosceles triangle.

Option (3) and Option (5) are the correct options.

Answer:

$\mathrm{C.\:}25$

Step-by-step explanation:

Notice how each congruent square is divided into four equal parts. Since each square has four parts and there are four squares, there are $16$ of these parts in total. Because each of these parts make up $\frac{1}{4}$ of each square, all parts are equal. Therefore, you can count the total number of shaded parts to get your percentage.

The top left and bottom right both have one part shaded each for a total of $2$ parts.

The top right and bottom left have $0.5$ and $1.5$ parts shaded, respectively, for a total of $2$ parts.

Therefore, in total, there are $2+2=4$ parts shaded out of $16$ total parts.

Thus, the percentage of the total area that is shaded is:

$\frac{4}{16}=\frac{1}{4}=\fbox{$25\%$}$ .
