what is 1 and 5/32 as a decimal

Answers

Answer:

1 5/32 is equal to 1.15625 in decimal form.

Step-by-step explanation:

Hope this helped, Have a Great Day!!

1 and 5/32 is equivalent to 1.15625 as a decimal.

To convert the mixed number 1 and 5/32 to a decimal, you need to combine the whole number and the fractional part.

First, you convert the fractional part to a decimal.

The denominator of 32 tells you that there are 32 equal parts in a whole.

To determine the value of 5/32, you divide the numerator (5) by the denominator (32):

5 ÷ 32 = 0.15625

Next, you add the decimal value of the fractional part (0.15625) to the whole number (1):

1 + 0.15625 = 1.15625

Therefore, 1 and 5/32 is equivalent to 1.15625 as a decimal.

Pentru sala de mese a scolii s-au adus 12 scaune si 7 mese, plătindu-se 320lei.Știind că 4 scaune costă cât trei mese, află prețul unui scaun și prețul unei mese.

Answers

Răspuns:

Costul scaunului = 15

Costul mesei = 20

Explicație pas cu pas:

Dat fiind:

Să prețul scaunelor = c; pretul mesei = t

12c + 7t = 320 - - - (1)

4c = 3t; c = 3/4 t - - - (2)

Introducerea c = 3 / 4t în (1)

12 (3 / 4t) + 7t = 320

9t + 7t = 320

16t = 320

t = 320/16

t = 20

c = 3 / 4t

c = 3/4 (20)

c = 15

Costul scaunului = 15

Costul mesei = 20

What is the volume of the following rectangular prism?

Answer:

Step-by-step explanation:

The volume of the rectangular prism is V = 64 units³

What is the volume of a prism?

A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.

The volume of a prism is the product of its base area and height

Volume of Prism = B x h

where B = base area of prism

h = height of prism

Given data ,

Let the volume of the rectangular prism be represented as V

Now , the height of the prism is H = 4 units

The length and width of the prism is 1 and 16 units respectively

So , the base area of the prism B = 16 units²

Now , Volume of Prism = B x h

On simplifying , we get

The volume of rectangular prism V = 16 x 4

The volume of rectangular prism V = 64 units³

Hence , the volume of the rectangular prism is 64 units³

which value if x makes this proportional true? 14/20=56/x A.x=62 B.x=70 C.x=80 D.x=100​

Answers

Answer:  C) x = 80

==================================================

Work Shown:

Let's cross multiply to get the following

14/20 = 56/x

14*x = 20*56

14x = 1120

x = 1120/14

x = 80

-------------------

As a way to check the answer, we can type 14/20 - 56/80 into the calculator and we should get 0. I'm taking advantage of the rule that if A = B, then A-B = 0. This trick is handy to check if two sides of any equation are equal to one another.

your answer will be 80 pretty sure

4 intervals of 1000 feet
c.
6 intervals of 500 feet
b.
5 intervals of 1000 feet
d.
7 intervals of 500 feet

Answers

Answer:

D. 7 intervals of 500 feet

Step-by-step explanation:

Got it right

Jamie used 5 intervals of 1000 feet as per the given data. The correct option is b.

What are tallies and frequencies?

A tally chart is a straightforward method of recording and counting frequencies. Each occurrence is represented by a tally mark, and every fifth tally is drawn diagonally to form a five-pointed star.

The first interval has a frequency of 7, which corresponds to the first 7 data points in the list:

1010

1470

1600

2000

2800

1053

1495

The last interval has a frequency of 2, which corresponds to the last 2 data points in the list:

2310

4260

Since there are 25 data points in total, and the first 7 and last 2 have been accounted for, that leaves 16 data points for the remaining intervals.

If Jamie used 1000-foot intervals, each interval would cover a 1000-foot range. The remaining data points range from 1200 to 4200 feet, so they are divided into 1000-2000, 2000-3000, and 3000-4000 foot intervals.

If Jamie used 500-foot intervals, each interval would cover a 500-foot range.

Thus, because the remaining data points range from 1200 to 4200 feet, they are divided into 1000-1499, 1500-1999, 2000-2499, 2500-2999, 3000-3499, 3500-3999, and 4000-4499 foot intervals.
