How much wrapping paper is needed to cover a box (rectangular prism) that measures 6 feet by 2.5 feet by 3 feet?
Answer:
81 feet ²
Step-by-step explanation:
Given that:
Dimension of rectangular prism :
6 feets by 2.5 feets by 3 feets
To obtain the amount of wrapping paper required to cover the box ; we find the area of the box ;
Area of box = 2(wl + hl + hw)
Area of box = 2(6*2.5 + 6*3 + 2.5*3)
Area of box = 2(15 + 18 + 7.5)
Area of box = 81 feet²
Brazil's currency is called the real and is denoted with this symbol: R$. A plumbing contractor allotted R$10,236 in his bank account to complete three residential jobs. If he estimates Job 1 to cost R$2,477, Job 2 to cost R$2,263 and Job 3 to cost R$3,218, how much money will he have left in the account for unexpected costs?
Step-by-step explanation:
I added together his estimations and then subtracted the total from how much money was in his bank.
2,477+2,263+3,218=7,958
10,236-7,958=2,278

The measures of the angles of a triangle are shown in the figure below. Solve
for x.
30°
(4x-4)
In this triangle it is given that one angle if of 30⁰ and another one is of 90⁰
so By using ANGLE SUM PROPERTY we can solve it
so,
30⁰+ 90⁰ + 4x - 4⁰ = 180⁰(ASP)
120⁰ + 4x - 4 = 180⁰
4x - 4 = 60⁰
4x = 64
x = 16⁰
Hence solved

The ratio of yellow flowers to the total number of flowers in a bucket is 5 to 9. How many flowers are yellow if there are 45 lowers in all
Answer:
There are 25 yellow flowers.
Step-by-step explanation:
The ratio is yellow/all and 5/9.
We know that all the flowers in total equal 45, which is a multiple of 9.
So 45 divided by 9 = 5.
So all I had to do was multiply 5/9 times 5/5.
So then we get the ratio of 45 total flowers with 25 yellow flowers.

A bucket contains stones and seashells. There are 40 seashells in the bucket and the ratio of stones to seashells is 7: 4. Find the number of stones in the bucket.
Answer:
There are 70 stones in the bucket.
Step-by-step explanation:
If there are 40 seashells in the bucket and the ratio of stones to seashells is 7:4, then there are 70 stones, because 4 x 10 = 40, and 7 x 10 = 70

Ingrid has $28 to buy oil paints for her painting class. Each tube of paint costs $8. How many tubes can she buy? Do not include units in your answer.
Answer:
3
Step-by-step explanation:
You have to divide 28 divided by 8.
28/8 = 3.5
I'm pretty sure you can't buy half a tube of paint, so Ingrid would only be able to buy 3.

Answer:
15v^5 +4v^3 -24v^2
Step-by-step explanation:
Distributing the minus sign, we have ...
3v^5 +8v^3 -10v^2 +12v^5 -4v^3 -14v^2
= (3 +12)v^5 +(8 -4)v^3 +(-10 -14)v^2
= 15v^5 +4v^3 -24v^2
show that the equation x^3-3x^2+3=0 has a solution between x=2 and x=3
The equation has 3 solutions (determined by the degree of polynomial and non-extreme case).
If you use cubic equation to try and solve the equality you get
[tex]x_1\approx-0.88 \\ x_2\approx1.35 \\ x_3\approx2.53[/tex]
Clearly third one is in [tex](2,3)[/tex] so the statement that one solution is between 2 and 3 is true.

in a class of 50 student,18 offered mathematics, 21 offered chemistry while 16 offered biology, 7 student offered mathematics and biology, 9 student offered chemistry and biology while 5 student offered the three subjects. find the number that offered mathematics but neither chemistry nor biology.
b the number of students that offered biology but neither chemistry nor mathematics and the number that offer biology neither mathematics nor chemistry
Answer:
ill try:
18 - 7 = 11
11 - 5 = 6
6 offered math but neither chem nor bio.
16 - 7 = 9
9 - 9 = 0
0 - 5 = -5
so 0 offered bio but neither chem nor math.

Answer:
missing angle = 41, b. 45, c. 72
Step-by-step explanation:
A circle has 360 degrees, so add all of the existing angles
48+45+129+97 = 319 and 360-319 = 41
25/200 = 12.5% so 12.5% of 360 = .125x360 = 45
Sector 129 represents 129/360 = 35.83% so 200x.3583=72 cars

TW is the mid segment of the trapezoid RSUV. If UV equals - Z +15, TW = -4z + 55, and RS = -3z + 43 what is the value of Z?
Answer:
13
Step-by-step explanation:
A trapezoid is a quadrilateral (has four sides and four angles) with two parallel opposite sides. These parallel sides are known as the bases.
According to the mid segment theorem of a trapezoid, The mid segment of a trapezoid is half the lengths of the two parallel sides.
Given that TW is the mid segment, UV and RS are the parallel bases, hence:
[tex]TW=\frac{UV+RS}{2} \\\\-4z+55=\frac{(-z+15)+(-3z+43)}{2} \\\\-4z+55=\frac{-4z+58}{2} \\\\-8z+110=-4z+58\\\\-4z+8z=110-58\\\\4z=52\\\\z=13[/tex]

Answer:
90/13, 45/13
Step-by-step explanation:
[tex] - 2 = x \\ 7x + 9y = - 45 \\ \\ 7 \times ( - 2)y + 9y = - 45 \\ y = 9 \\ \\ 7x + 9 \times 9 = - 45 \\ x = - 18 \\ (x.y) = (- 18.9) \\ \\ [/tex]
Simplify:
[tex] - 2 \times 9 = - 18 \\ 7 \times ( - 18) + 9 \times 9 = - 45 \\ - 18 = - 18 \\ - 45 = - 45[/tex]
