Which value is furthest from 0 on the number line? a. 30 b. -31 c. 30.5 d. -31.5

Mathematics
2 answers:
Lena [83]3 years ago
4 0

Answer:

d. -31.5

Step-by-step explanation:

Distance will be positive  

a. 30

To get to 30 from 0   we go 30 units  so the distance is 30

b. -31

To get to -31 from 0 we go 31 units  so the distance is 31

c. 30.5

To get to 30.5 from 0 we go 30.5 units  so the distance is 30.5

d. -31.5

To get to -31.5 from 0 we go 31.5 units  so the distance is 31.5

(i.) CA = πrl
CA = π (5*13)
CA = 65π

(ii.) TA = πrl + πr^2
TA = 65π + π (5^2)
TA = 65π + 25π
TA = 90π

(iii.) To get the height of the cone, you have to use the Pythagorean theorem. Plug in the radius for a and the slant height for c.

a^2 + b^2 = c^2
5^2 + b^2 = 13^2
25 + b^2 = 169 Height = 12
b^2 = 144
b = 12

(iv.) v = (1/3)πr^2h
v = (1/3)π(5^2)*12
v = (1/3)π(25*12)
v = (1/3)π*300
v = 100π

When 43,55 and 67 are divided by a certain number, the remainder is 7 in each case. Find the number? ​
siniylev [52]

Answer:

12

Step-by-step explanation:

First subtract 7 from 43, 55 and 67

43 - 7 = 36 ;  55 - 7 = 48  ;  67 - 7 = 60

Now find the GCF of 36 , 48 , 60

36 = 2 * 2 * 3 * 3

48 = 2 * 2 * *2*2 * 3

60 = 2 * 2 * 3 * 5

GCF = 2 * 2 * 3 = 12

The required number is 12

When you divide 43 by 12, the remainder is 7.

When you divide 55 by 12, the remainder is 7

When you divide 67 by 12, the remainder is 7

Which pyramids with base area B and height h have equal volumes?
Pachacha [2.7K]
Option A:

V = 1/3 * b^2 * h

V = 1/3 * 10.5^2 * 6

V = 1/3 * 110.25 * 6

V = 220.5

Option B:

V = 1/3 * b^2 * h

V = 1/3 * 3.6^2 * 8

V = 1/3 * 12.96 * 8

V = 34.56

Option C:

V = 1/3 * b^2 * h

V = 1/3 * 4.2^2 * 12

V = 1/3 * 17.64 * 12

V = 70.56

Option D:

V = 1/3 * b^2 * h

V = 1/3 * 6^2 * 8.4

V = 1/3 * 36 * 8.4

V = 100.8

I guess it's 'None of the Above'

What is the value of y? Enter your answer in the box. y = An isosceles triangle with vertices labeled A, B, and C. Side B C is t
masha68 [24]

Answer:

y = 5

Step-by-step explanation:

Given:

An isosceles triangle ABC with AB = AC.

∠A = (4y+10)\°

∠B = 75\°

∠C = (3x)\°

We know that, for an isosceles triangle, the angles opposite equal sides are also equal to each other.

Therefore, ∠B = ∠C

⇒ 75 = 3x

⇒ x=\frac{75}{3}=25

∴ ∠C = 3\times 25=75°

Now, the sum of all the interior angles of a triangle is always 180°.

\angle A + \angle B + \angle C=180\\(4y+10)+75+75=180\\4y+10+150=180\\4y+160=180\\4y=180-160\\4y=20\\y=\frac{20}{4}=5

Therefore, the value of 'y' is 5.
