64

Step-by-step explanation:

.64 = Sixty-four hundredths or 64/100

That is 64% or 64 voters out of 100

Answer: If you spend 7 hours a week studying for English, and 4.5 hours studying for math what is the ratio of time spent studying math to studying English?

Math: English

4.5: 7 Now you divide both sides by 4.5 to get 1 on one side

1: 1.555556

So the ratio of time spent studying math to english is 1 to 1.555556. Hope I helped

Answer:

Row D

Step-by-step explanation:

y = 2x - 3

if x = 10

y = 2 * 10 - 3

= 20 - 3

= 17

so row d is incorrect.

Answer:

√15

Step-by-step explanation:

Assuming that it is:

[tex]15^\frac{1}{2}[/tex]

Exponent rule for fractional exponents are:

[tex]x^\frac{a}{b}=\sqrt[b]{x^a}[/tex]

Apply rule:

[tex]15^\frac{1}{2}=\sqrt{15}[/tex]

Hope this helps!

t (23) ≤ 97 - 23

The minus 23 at the back represents the feet she already descended before what the question wants us to calculate

≤ is used instead of < because it states more than, not "equal or more than" (meaning 97 sharp is fine)

Answer: Day 6

Step-by-step explanation: Every 3 days 1 pound of hay is used every day 1 pound of grain is used. There are 10 pounds of grain and 8 pounds of hay. On the 6th day there are 6 pounds of hay left and 6 pounds of grain left.

um i don't understand im sorry

Answer:

Ans : =x

brainliest plsssssss

Step-by-step explanation:

Let's simplify step-by-step.

−2(x+8)+1(3x+16)

Distribute:

=(−2)(x)+(−2)(8)+(1)(3x)+(1)(16)

=−2x+−16+3x+16

Combine Like Terms:

=−2x+−16+3x+16

=(−2x+3x)+(−16+16)

=x

Answer:

The cost per pound is: $5.45 per pound

Step-by-step explanation:

Given

8kg ham costs $12/kg

To determine

Find the cost per pound

As

1 kg = 2.2 pounds  

Weight of 8kg in ponds = 8 × 2.2 = 17.6 ponds

Cost of ham/pound = $12/2.2 pounds

                                 = $5.45 per pound

Thus, the cost per pound is: $5.45 per pound

Answer:

11 1/5

Step-by-step explanation:

subtract 9 from both sides

5x = 56

divide both sides by 5

x = 56/5

11 1/5

Answer:

11.2 because 65 - 9 = 56 and 56 divided by 5 is 11.2

Answer:

Step-by-step explanation:

Answer:

3(3y-1)

Step-by-step explanation:

To find out which expression is equivalent, expand and simplify the options listed to see which one equals 9y-3.

Let's try the second option. To simplify the expression, use the distributive property. So, multiply each term in the parentheses by 3:

[tex]3(3y-1)\\= 9y-3[/tex]

Thus, the answer would be the second option.

45b - 10a

Step-by-step explanation:

Answer:

5(9a-2b)

Step-by-step explanation:

This is a polynomial and you have to factor it.

GCF of 45a and 10b is 5

5(9a-2b)

Answer:

a^n = 36 + (n-1) * 3

Step-by-step explanation:

Explicit formula for arithmetic sequences: a^n = a^1 + (n-1) * d

In this case, a^1 = 36 and common difference/d = 3

So...

a^n = 36 + (n-1) * 3 is the explicit formula for this sequence.

Answer:

Corresponding angles

Step-by-step explanation:

<3 and <7 lie on the same side of the transversal line. Each angle also is located on the outside of each parallel lines cut across by the transversal.

Therefore, <3 and <7 are corresponding angles.

Answer:

12 marbles

Step-by-step explanation:

0.15 times 80= 12

so

15% of 80 is 12

Brainliest ?!?!!?!?

The linked answer is wrong because that integral gives you the net displacement of the object, not the total distance.

To get the distance, you have to integrate the speed (as opposed to velocity), which involves integrating the absolute value of the velocity function.

[tex]\mathrm{distance} = \displaystyle\int_1^5 |\sin(t)| \,\mathrm dt[/tex]

By definition of absolute value,

[tex]|\sin(t)|=\begin{cases}\sin(t)&\text{for }\sin(t)\ge0\\-\sin(t)&\text{for }\sin(t)<0\end{cases}[/tex]

Over this particular integration interval,

• sin(t ) ≥ 0 for 1 ≤ t < π, and

• sin(t ) < 0 for π < t ≤ 5

so you end up splitting the integral at t = π as

[tex]\mathrm{distance} = \displaystyle\int_1^\pi \sin(t)\,\mathrm dt + \int_\pi^5 (-\sin(t))\,\mathrm dt[/tex]

Now compute the distance:

[tex]\mathrm{distance} = -\cos(t)\bigg|_1^\pi + \cos(t)\bigg|_\pi^5[/tex]

[tex]\mathrm{distance} = -(\cos(\pi) - \cos(1)) + (\cos(5) - \cos(\pi))[/tex]

[tex]\mathrm{distance} = -2\cos(\pi) + \cos(1) + \cos(5) \approx 2.82[/tex]

making B the correct answer.

Answer:

Step-by-step explanation:

The area of a trapezium is given as;

Area = [tex]\frac{1}{2}[/tex](a + b)h

where: a is the length of the upper side, b is the length of its base and h is its height.

This implies that; a = x - 4, b = x + 5, h = 2x and area = 351

Thus,

351 =  [tex]\frac{1}{2}[/tex]((x - 4) + (x + 50)) 2x

      = (x - 4 + x + 5) x

531 = (2x + 1) x

      = 2[tex]x^{2}[/tex] + x

So that;

2[tex]x^{2}[/tex] + x - 531 = 0

This gives a quadratic equation.

Answer:

x = 3

Step-by-step explanation:

Measure of a triangle is 180° degree.

.·. 46 + 105 + 6x + 11 = 180

.·. 162+6x=180

.·. 6x=180-162

.·. 6x= 18

.·. x= 18/6

.·. x= 3
