Answer: 63.36 in
Step-by-step explanation: To find the area of the base its just 4.8x4.8= 23.04 and the area of the triangle is (4.8x4.2)/2= 10.08 multiply that by 4 since there are 4 sides thats 40.32 and add the area of the base making it 63.36
What is 588.75 to the nearest cubic inch?
Answer:
589
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.
588.75 --> 589
Answer:
589
Step-by-step explanation:
588.75 rounded up would be 589!

Answer:
b) AD || BC
Step-by-step explanation:
The missing options are:
a) AB || DC
b) AD || BC
c) none
The missing drawn is shown in the figure attached.
The only way that m∠8 = m∠4 is that segment AD and segment BC are parallel. Because in that case, they are alternate angles, and therefore, they are equal. Notice that angle 8 lies on side AD and angle 4 lies on BC
Answer:
b) AD || BC

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.
Base and ExponentA base number and an exponent are typically used to denote a power.
What is base value?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.
What is exponent?The exponent, a little number printed above and to the right of the base number, provides the multiplicative power of the base number.
Calculation for the exponent of 2: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.
Calculation for the exponent of -2: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.

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

Answer:
Step-by-step explanation:
radius of the circle=12 cm / 2=6 cm
Area of the square=side²=(12 cm)²=144 cm²
Area of the circle=πr²=(3.142)(6 cm)²≈(3.142)*36 cm²≈113.112 cm²
Area of the four sides between the square and the circle=
=Area of the square - area of the circle=144 cm²-113.112 cm²=30.888 cm²
shaded area =30.888 cm²/4=7.722 cm²

4
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.
What is probability?
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.

Kai was making pizza for lunch. They used 1/4 of a package of pepperoni and 1/6
of a package of sausage. How much more pepperoni than sausage did Kai use on
their pizza?
Answer:
1/12 more pepperoni than sausage
Step-by-step explanation:
to make 1/6 and 1/4 have the same denominator you multiply top and bottom by 6 and 4.
1/6*4 = 4/24
1/4*6 = 6/24
6/24 - 4/24= 2/24= 1/12
