Answer:
A) 3.44 ft²
Step-by-step explanation:
before cutouts, the area was 4 x 4 = 16 ft²
the circles have a diameter of 2 ft each, and a radius of 1 ft
each circle has an area pf (3.14)(1²) = 3.14 ft²
3.14 x 4 = 12.56 ft²
16 - 12.56 = 3.44 ft² left

What is the area of the logo?
Answer:
[tex]the \: area \: of \: the \: logo \: is \: {91cm}^{2} [/tex]
Step-by-step explanation:
To determine the area of the logo you have to calculate the area of the triangle and the square that comform it and then add the four areas.
Area of the square.
To calculate the area of the square you have to calculate the square of one of its sides, following the formula:
[tex]a = {a}^{2} [/tex]
Where "a" is the length of one of its side.
The side length of the square is a=7cm, so its area will be:
[tex]asquare = {7}^{2} \\ asquare = {49cm}^{2} [/tex]
Area of the triangles.
The three triangles are equal, they have a base equal to the side of the square, i.e. with a length of 7cm, and their height is h=4cm.
To calculate the area of one triangle, you have to multiply its base by its height and divide by 2, following the formula:
[tex]a = \frac{b.h}{2} \\ a = \frac{7.4}{2} \\ a = \frac{28}{2} \\ a = {14cm}^{2} [/tex]
The area calculated the correspond to one triangle, since all triangles are congruent, you have to multiply the said area by 3 to determine the area of three figures:
[tex]atriangles = 3a \\ atriangles = {42cm}^{2} [/tex]
Now that the area of all shape are calculated, you have to add them to determine the area of the logo:
[tex]alogo = asquare + atriangle \\ alogo = 49 + 42 \\ alogo = {91cm}^{2} [/tex]
Answer:
(7×7)+3(1/2×7×4)
49+42

The following are the ages (years) of 5 people in a room:
17, 21, 15, 15, 25
A person enters the room.
The mean age of the 6 people is now 25.
What is the age of the person who entered the room?
Answer:
57 years
Step-by-step explanation:
total=25*6=150
17+21+15+15+25+x=150
93+x=150
x=150-93
x=57
Answer:
age=57
Step-by-step explanation:
ages=17 21 15 15 25 ?
17+21+15+15+25=93(old mean)
17+21+15+15+25+?=25(new mean)
25(new mean)*6(number of numbers)=150
?=150-93=57
= 57

A total of 629 tickets were sold for the school play. They were either adult tickets or student tickets. There were 71 fewer student tickets sold than adult
tickets. How many adult tickets were sold?
Answer:
350 adult tickets were sold.
Step-by-step explanation:
let x = number of adult tickets
number of student tickets -> x-71
x - 71 + x = 629
2x - 71 = 629
2x = 700
x = 350

The circumference of the hub cap of a tire is 73.79 centimeters. Find the area of this hub cap. Use 3.14 for π. Use pencil and paper. If the circumference of the hub cap were smaller, explain how this would change the area of the hub cap.
The area of this hub cap is about __ square centimeters.
Answer:
433.5 cm²
Step-by-step explanation:
The formula for circumference is C = 2πr, where r is the radius.
Here, C = 2πr = 73.79 cm. Solving this for the radius, r, we get:
73.79 cm
r = ---------------- = 11.75 cm
2(3.14)
Then the area of the hubcap is A = πr², or, in this case,
A = 3.14(11.75 cm)² = 433.5 cm²
Answer:
simple answer (and rounded for u) = 434 centimeters squared! hope it helps peeps

Square OPQR is inscribed in triangle ABC. The areas of △AOR, △BOP, △CRQ are 1, 3, and 1, respectively. What is the area of square OPQR?
Answer:
9 units²
Step-by-step explanation:
We know that ΔCRQ and ΔBOP are right triangles because RQ and OP are perpendicular to CB.
ΔAOR must also be a right triangle because ∠AOR = ∠OBP and ∠ARO = ∠RCQ.
Because of the Angle-Angle-Angle theorem, we know that ΔAOR ≅ ΔBOP ≅ ΔCRQ.
AR/AO = OP/PB
3(1/2)(AR)(AO) = (1/2)(OP)(PB)
PB = 6, OP = 3
3 x 3 = 9 units²
The area of square OPQR is 9 units².
Calculation of the area of square:Since
ΔCRQ and ΔBOP are right triangles since RQ and OP are perpendicular to CB.
Also,
ΔAOR must also be a right triangle due to ∠AOR = ∠OBP and ∠ARO = ∠RCQ.
So it can be like
AR/AO = OP/PB
3(1/2)(AR)(AO) = (1/2)(OP)(PB)
PB = 6, OP = 3
= 3 x 3
= 9 units²
hence, The area of square OPQR is 9 units².

Takashi Caldwell has health insurance that pays 80 percent of coverage charges after a $150 deductible. She received a statement for $350 of covered charges. How much will Takashi have to pay?
Subtract the deductible from the total:
350 - 150 = 200
Takashi then needs to pay 20% of what is left.
200 x 0.20 = 40
Takashi has to pay the 150 deductible plus 40 for a total of $190
