Answer: [tex]4.14\ \text{pints}[/tex]

Step-by-step explanation:

Given

Keiko uses 6.9 Pints of blue and white paint

If the fraction of blue paint is [tex]\frac{2}{5}[/tex], then thr fraction of white paint is

[tex]1-\dfrac{2}{5}=\dfrac{3}{5}[/tex]

Amount of white paint is

[tex]\Rightarrow \dfrac{3}{5}\times 6.9=4.14\ \text{pints}[/tex]

Volume of a cube = edge x edge x edge

volume of one cube= 4x4x4=64

Answer:

Step-by-step explanation:

We must rewrite 7x^2 = 9 + x in standard form first:  7x^2 - x - 9 = 0.

The coefficients are 7, -1 and -9, and so the discriminant b^2 - 4ac is

(1)^2 - 4(7)(-9) = 253.

The roots are:

       -(-1) ± √253           1 ± √253

x = --------------------- = --------------------

              2(7)                       14

Answer:

250

Step-by-step explanation:

Every number is multiplied by 5

2 x 5 = 10

10 x 5 = 50

50 x 5 = 250

Answer:

20

Step-by-step explanation:

Given data

Let the number of magic tricks be x

we are told that she knows 70% of card trick which is 14 card tricks

hence we have

70/100*x= 14

0.7x= 14

x= 14/0.7

x=20

Hence the number of magic tricks she knows is 20

Answer:

16

Step-by-step explanation:

Answer:

5% times 3=15%

4% times 3=12%

15-12=3

1300 times 0.03= $39

39 dollars.

p ² + 6 is even if p ² is even (the sum of two even numbers is even), and this happens only if p itself is even, i.e. if p = 2 since 2 is the only even prime.

All other primes p are odd, so p ² would be odd, and adding 6 would not change that (odd + even = odd).

Answer:94 m^2

Step-by-step explanation:

surface area equation for rectangle is 2*(a*b + a*c + b*c)

where a=4 b=5 and c=3

so substitute in all numbers and get:

Surface Area = 2×(4×5 + 4×3 + 5×3)

do the maths and got a solid 94 meters

(I squared because in this equation you are multiplying numbers that equal the area of a surface and not the whole volume which would be cubed)

Answer:

radius = 7.5 cm

Step-by-step explanation:

Since M is the midpoint of the chord AB then OM is perpendicular to AB

Using Pythagoras' identity in right triangle OMB with hypotenuse OB, the radius of the circle, then

OB² = OM² + MB² = 4.5² + 6² = 20.25 + 36 = 56.25 ( take square root of both sides )

OB = radius = [tex]\sqrt{56.25}[/tex] = 7.5

The value of z in the given arrangement is 2 m.

Similar triangles are the triangles that look similar to each other, but their sizes might not be exactly the same.

Also,

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.

Given that, an engineer needs to find the length of a beam to support the beam holding the wall, the two beams are perpendicular to one another, and a=4 m and b=1 m, we need to find z.

So, here we will use the concept of similar triangles,

According to the definition the corresponding sides are in proportion.

So, we get,

z/a = b/z

z² = 4

z = 2

Hence, the value of z in the given arrangement is 2 m.

Answer:

d. 20°

Step-by-step explanation:

First, we need to solve for m<Q

m<Q+m<R+m<S=180°

where m<R=90° and m<S=70°

m<Q+90°+70°=180°

m<Q=20°

Since m<Q=m<M

Then, m<M=20°

Answer:

2,320

Step-by-step explanation:

4.2% gets taken every year and there is 10 year,so 4.2% s uqual to 0.042,so just mutiply 4000 by 0.042 which  is 168,then times 168 by 10 which brings you to 1680 and 4000 subtracyed by 1680,which equals 2,320

Answer:

275 m^3

Step-by-step explanation:

The volume of a triangular pyramid is V=(1/3)Ah, where A is the area of the triangular base and h is the height.

First, let's find A, the area of the base. The area of a triangle is bh/2, where b is the base and h is the height.

In this question, 5 is the base and 15 is the height, so A=5*15/2=75/2.

Now we know A is 75/2, so let's go back to the formula for the volume of a pyramid. We are given h is 22, so

V=(1/3)(75/2)*22=275

The statement (D) "the fewest students prefer black Model A1 calculators" is correct.

It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the total frequency cell to total frequency.

There is the fewest value is 0.05

More students prefer Model C3 calculators than Model A1 calculators, mathematically,

0.30 > 0.45 (false)

More students prefer black calculators than white calculators, mathematically,

0.35 > 0.65 (false)

Similarly, statement third is also false.

Thus, the statement (D) “the fewest students prefer black Model A1 calculators” is correct.
