Em uma competição esportiva uma equipe ganhou 80 medalhas sendo que 25% de ouro 35% de prata e o restante de blusa e qual o número de medalhas de bronze que essa equipe ganhou
Answer:
32 medals
Step-by-step explanation:
Given that
The team wons 80 medals
out of which 25% is gold
35% is silver
and rest is bronze
we need to find out the number of bronze medals that win by the team
The total percentage is 100
So, the remaining percentage is
= 100 - 25 - 35
= 40%
So, the number of bronze medal should be
= 40% of 80 medals
= 32 medals

A parallelogram has an area of 300 square kilometers and a height of 20 kilometers. What is the length of the base?
Answer: the length of the base is 15 kilometers.
Step-by-step explanation:
formula : Area of parrallelogram = Length of base x height
Given: Area of parallelogram = 300 square kilometers
height = 20 kilometers
Substituting values in the formula , we get
300 = Length of base x 20
Length of base = [tex]\frac{300}{20}[/tex]
= 15 kilometers
Hence, the length of the base is 15 kilometers.

Fruntum A bucket is 20cm in diameter at the open end,12cm in diameter at the bottom,and 16cm deep. To what depth would the bucket fill a cylindrical tin 28cm in diameter?
Answer:
The depth is 5.33cm
Step-by-step explanation:
Given
[tex]D =20cm[/tex] --- diameter at open end
[tex]d = 12cm[/tex] --- diameter at bottom
[tex]H=16cm[/tex] -- depth
[tex]d_c = 28cm[/tex] --- diameter of the cylinder
Required
The depth the bucket will fill the cylinder
First, calculate the radii at the ends of the bucket
[tex]R=D/2 =20cm/2 = 10cm[/tex]
[tex]r=d/2 =12cm/2 = 6cm[/tex]
The volume of the bucket (frustum) is:
[tex]V = \frac{1}{3} \pi H(R^2 + Rr + r^2)[/tex]
[tex]V = \frac{1}{3} *\pi * 16 * (10^2 + 10*6 + 6^2)[/tex]
[tex]V = \frac{1}{3} *\pi * 16 * 196[/tex]
[tex]V = 1045.33\pi cm^3[/tex]
The volume of a cylinder is:
[tex]V = \pi r_c^2h_c[/tex]
Where:
[tex]r_c = d_c/2 = 28cm/2 =14cm[/tex]
So, we have:
[tex]1045.33\pi = \pi * 14^2 * h_c[/tex]
[tex]1045.33\pi = \pi * 196 * h_c[/tex]
[tex]1045.33\pi = 196\pi * h_c[/tex]
Make h the subject
[tex]h_c = \frac{1045.33\pi}{ 196\pi}[/tex]
[tex]h_c = \frac{1045.33}{ 196}[/tex]
[tex]h_c = 5.33[/tex]

= 22°. Which equation can you use to find the value of c = AB?
Answer:
7.7
Step-by-step explanation:
use law of cosines
c² = a² + b² - 2ab * cosC
c² = 16² + 10² - 2(16)(10)cos22
c² = 256 + 100 - 320 * 0.927183854566787
c² = 59.3011665386
c ≈ 7.7
Answer:
You can use the Law of Cosines to solve for c:
c2 = a2 + b2 − 2ab cos C = 162 + 102 − 2(10)(16) cos 22°.

-6x+y= -2
-3x-6y= 12
Answer:
Ans: x=0
y= -2
Step-by-step explanation:
-6x+y= -2--------- (1) × 6
-3x-6y= 12--------(2) × 1
-36x+6y= -12-----(3)
-3x-6y= 12--------(2)
(3)+(2)
-36x+6y+(-3x-6y) = -12+12
⇒ -36x+6y-3x-6y = 0
⇒ -36x-3x = 0
⇒ -39x=0
⇒ x= 0/-39
∴ x = 0
Substitute x = 0 into (1)
-6x+y= -2
⇒-6(0)+y= -2
⇒0+y= -2
∴y = -2
Ans: x = 0
y = -2
Check:
-6x+y= -2--------- (1)
= -6(0)+(-2)
= 0 - 2
= -2 ✔
-3x-6y= 12--------(2)
= -3(0)-6(-2)
= 0+12
= 12 ✔

QUESTION:
The angled of a triangle are (x-40), (x-20), (1/2- 10), find x
Answer:
x=124.75
Step-by-step explanation:
Sum of angles of a triangle=180°
(x-40)+(x-20)+(1/2- 10)=180°
(x-40)+(x-20)+(−9.5)=180°
x-40+x-20−9.5=180°
x+x-40-20-9.5=180°
2x−69.5=180°
2x=180°+69.5
2x=249.5
2x/2=249.5/2
x=124.75

Step-by-step explanation:
QR= 1.5 inches
TS= 2 inches
TP= 3.8 inches
RS= 1.4 inches
PQ= 2.6 inches
now complete ur promise
Answer:
Step-by-step explanation:
Remark
The question says to increase the lengths of each side by a factor of 1.5.
That means that every measurement we see on the diagram is multiplied by 1.5
QR = given length times 1.5
given length = 1.5
QR = 1.5 * 1.5
QR = 2.25
TS = given length * 1.5
TS = 2 * 1.5
TS = 3
TP = given length * 1.5
TP given = 3.8
TP = 3.8 * 1.5
TP = 5.7
RS = given length * 1.5
given length = 1.4
RS = 1.4 * 1.5
RS = 2,1
PQ = given length * 1.5
given length = 2.6
PQ = 2.6 * 1.5
PQ = 3.9
Circle D is shown. Angles F A E, F D E, and F B E intercept arc F E. ∠FAE measures 72°. What other angle must measure 72°? ∠BFD ∠DEA ∠EDF ∠FBE
Answer:
Option D, ∠FBE
Step-by-step explanation:
The image for the question is attached herewith
Solution
As per the property of arc, angles subtended by the same arc (chord) on the circumference of a circle have equal measures.
∠FAE is an angle subtended by the arc FE that touches the circle at point 'A'.
∠FBE is also subtended by the arc FE at the point 'B'.
Therefore, we must have
m∠FAE = m∠FBE.
Since, m∠FAE = 72°, so m∠FBE = 72°.
Hence, option D, ∠FBE

Its D

Erica took out a loan to buy her new motorcycle. The purchase price of the motorcycle was $11349.00 plus 5% GST and 7% PST. She pays $409.00 per month on her loan, which has a term of 3 years. How much more is she paying than the purchase price? a. $2415.74 b. $1610.50 c. $2254.69 d. $2013.12
Answer:
The correct answer is D. $2,013.12.
Step-by-step explanation:
Since Erica took out a loan to buy her new motorcycle, and the purchase price of the motorcycle was $ 11349.00 plus 5% GST and 7% PST, and she pays $ 409.00 per month on her loan, which has a term of 3 years, for To determine how much more is she paying than the purchase price, the following calculation must be performed:
11,349 + (11349 x 0.12) = X
11,349 + 1,361.88 = X
12,710.88 = X
409 x 12 x 3 = X
4,908 x 3 = X
14.724 = X
14,724 - 12,710.88 = X
2,013.12 = X
Therefore, Erica is paying $ 2,013.12 more than the purchase price.

Answer:
Option C.
Step-by-step explanation:
We know that, for a value a > 1.
if b > c, then:
a^b > a^c
Now, this means that if we have two functions:
f(x) = x^n
g(x) = x^m
and m > n
then for large values of x, g(x) will be larger than f(x), because g(x) has a larger exponent.
now, is also true that:
f(x) = x^n
g(x) = n^x
for n > 1
For large values of x, g(x) will be larger than f(x), again, because for larger values of x g(x) will have a really large exponent, thus it grows really fast.
Then we can conclude that for the functions:
f(x) = 3*x
g(x) = 3*x^2
h(x) = 2^x
For a given value of x, h(x) will exceed the other two functions.
This can be seen in the graph below, where:
h(x) is purple, g(x) is blue, and f(x) is green.
We can see that eventually, h(x) exceeds the other two.
The correct option is C.
