Which two numbers doesStartRoot 61 EndRoot lie between on a number line? 7.7 and 7.8 7.8 and 7.9 7.9 and 8.0 8.0 and 8.1

Answer:

[0, infinity)

Step-by-step explanation:

The domain is including all numbers from 0 to infinity.

The reason negative numbers are not included is because of the [tex]\sqrt{x}[/tex]. A negative number cannot be included there, otherwise it would be what's called an "imaginary number" (i).

Therefore, every number besides negative numbers are included in the domain.

Answer:

denominator-of a fraction the number below the horizontal bar

numerator-of a fraction the number above the horizontal bar

fraction- ??? I don't see the definition

decimal fraction-symbol with three parts: a horizontal bar, a whole number above the bar, and a whole number below the bar number what's up value less than one, written place value notation, using a decimal point

percent-per hundred; out of every hundred; hundredths

improper fraction - fraction with a numerator greater than its denominator, giving it a value greater than 1

mixed number - number with a whole number part and a fraction part

Answer:

The area of trapezoid is 39.6cm²

Step-by-step explanation:

Given that the formula of area of trapezoid is A = 1/2×(a+b)×h where a and b is the length and h is the height. So you have to substitute the values into the formula :

[tex]area = \frac{1}{2} \times (a + b) \times h[/tex]

[tex]let \: a \: = 8.9 \\ let \: b \: = 5.5 \\ let \: h \: = 5.5[/tex]

[tex]area = \frac{1}{2} \times (8.9 + 5.5) \times 5.5[/tex]

[tex]area = \frac{1}{2} \times 14.4 \times 5.5[/tex]

[tex]area = \frac{1}{2} \times 79.2[/tex]

[tex]area = 39.6 {cm}^{2} [/tex]

 Answer: The area is 39.6

Step-by-step explanation:

First multiply 5.5×5.5= 30.25

Then subtract 8.9 - 5.5=3.4

Then multiply 5.5 x 3.4=18.7

Divide 18.7/2=9.35

Add 30.25 + 9.35 =39.6

Good luck on your assignment

For the base value of 4, if the exponent is 2; the value will be 16.

For the base value of 4, if the exponent is -2; then value will be 1/16.

A base number and an exponent are typically used to denote a power.

The total number of digits required to express numbers in a number system is known as the base in mathematics. What number is being multiplied is revealed by the base number.

The exponent, a little number printed above and to the right of the base number, provides the multiplicative power of the base number.

The base number is given as 4.

The exponent is given as 2.

So, the number becomes,

=> [tex]4^{2} =4[/tex]×[tex]4[/tex]

= 16

Thus, the base 4 with exponent 2 becomes 16.

The base number is given as 4.

The exponent is given as -2.

So, the number becomes,

=> [tex]4^{-2} =\frac{1}{4^{2} }[/tex]

= [tex]\frac{1}{16}[/tex]

Thus, the base 4 with exponent -2 becomes 1/16.

Step-by-step explanation:

To find the nearest cubic inch, round your volume measurement down to the nearest whole number if the number to the right of the decimal point is less than 0.5 . If the decimal point is 0.5 or greater, round up.

In this case, your decimal point is 0.75 , which is greater  than 0.5 . This means we round up.

Answer:

1/4

Step-by-step explanation:

In a spinner which has 4 equal-sized sections., the probability of pointer must land on a purple section to win the game is 1/4.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

A spinner has 4 equal-sized sections. To win the game, the pointer must land on a purple section.  Thus, the number of favorable outcomes is,

[tex]P(\text {purple}) =1[/tex]

Total number of possible outcomes is 4 as there is 4 equal-sized sections. Thus, the probability of the pointer must land on a purple section is,

[tex]P=\dfrac{1}{4}[/tex]

Thus, in a spinner which has 4 equal-sized sections., the probability of pointer must land on a purple section to win the game is 1/4.
