Evaluate the expression for a = 4, b = 5, and c = −4. 17 − 7(a − b)2 =

Answer:

You know 18:3 and 6:1 are equivalent ratios because if you take 18:3 and divide both sides by 3, 18/3:3/3, then you will get 6:1, which is clearly equal to 6:1.

18:3  and 6:1  are equivalent ratio because two ratios are in proportion

Given :

We are given with two ratios 18:3  and 6:1

We need to show that two ratios are equal

Lets take ration 18:3

Both 18  and 3  are divisible by 3

We can write the ratio in fraction form

[tex]\frac{18}{3} \\[/tex]

When we divide both top and bottom by 3  , we get

[tex]\frac{6}{1}[/tex]

we can say that [tex]\frac{18}{3} =\frac{6}{1}[/tex]

Hence, the ratios are equivalent ratios

18:3  and 6:1  are equivalent ratios

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

The number of hours the battery will last if it loses 3/8 of its battery every hour is 1 hour 40.2 minutes.

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

The battery charge left in the phone = 5/8 of its battery

The battery loses every hour = 3/8 of its battery

The number of hours the battery will last if it loses 3/8 of its battery every hour:

= 5/8 ÷3/8

= 5/8 x 8/3

= 5/3

= 1.67 hours

This means,

1 hour = 60 minutes

Multiply 1.67 on both sides.

1.67 hours = 1.67 x 60 minutes

1.67 hours = 100.2 minutes

1.67 hours = 1 hour 40.2 minutes

Thus,

The number of hours the battery will last if it loses 3/8 of its battery every hour is 1 hour 40.2 minutes.

In ΔGHI, GI is extended through point I to point J.

[tex]m\angle GHI=(3x+13)^\circ,m\angle IGH=(x+8)^\circ,m\angle HIJ=(6x-5)^\circ[/tex]

To find:

The measure of angle GHI.

Step-by-step explanation:

According to exterior angle theorem, the measure of an exterior angle of a triangle is equal to the sum of measure of two opposite angles.

Using exterior angle theorem, we get

[tex]m\angle HIJ= m\angle GHI+m\angle IGH[/tex]

[tex](6x-5)^\circ=(3x+13)^\circ+(x+8)^\circ[/tex]

[tex](6x-5)^\circ=(4x+21)^\circ[/tex]

[tex]6x-4x=21+5[/tex]

[tex]2x=26[/tex]

Divide both sides by 2.

[tex]x=13[/tex]

Now,

[tex]m\angle GHI=(3x+13)^\circ[/tex]

[tex]m\angle GHI=(3(13)+13)^\circ[/tex]

[tex]m\angle GHI=(39+13)^\circ[/tex]

[tex]m\angle GHI=52^\circ[/tex]

Therefore, the measure of angle GHI is 52 degrees.

!well what I did. You know that 60 minutes=one hour. So I put 2 & 1/2 over 60.

Make 2 & 1/2 a improper fraction=5/2.

So 5/2 over 60

Then divide. 5/2 divided by 60 ( which is 60/1)

Then leave change flip, meaning leave the 5/2 change the division sign to multiplication, and flip, which you would flip 60/1 to 1/60

So we have 5/2 times 1/60. Multiply across. 5 times 1= 5. 2 times 60=120

So we have 5/120

Now we simplify 120 divided by 5 = 24. And 5 divided by 5 = 1

So 1/24

Answer:

[tex]d=\frac{\sqrt{97}}{6}\approx1.6415[/tex]

Step-by-step explanation:

We have the two points: (2, 5/2) and (8/3, 1).

And we want to find the distance between them.

So, we can use the distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

Let (2, 5/2) be (x₁, y₁) and let (8/3, 1) be (x₂, y₂). Substitute:

[tex]d=\sqrt{(\frac{8}{3}-2)^2+({1-\frac{5}{2})^2[/tex]

Evaluate the expressions within the parentheses. For the first term, we can change 2 to 6/3. For the second term, we can change 1 to 2/2. So:

[tex]d=\sqrt{(\frac{8}{3}-\frac{6}{3})^2+({\frac{2}{2}-\frac{5}{2})^2[/tex]

Evaluate:

[tex]d=\sqrt{(\frac{2}{3})^2+(-\frac{3}{2})^2[/tex]

Square:

[tex]d=\sqrt{\frac{4}{9}+\frac{9}{4}[/tex]

Add. We can change 4/9 to 16/36. And we can change 9/4 to 81/36. So:

[tex]d=\sqrt{\frac{16}{36}+\frac{81}{36}}[/tex]

Add:

[tex]d=\sqrt{\frac{97}{36}}[/tex]

We can separate the square roots:

[tex]d=\frac{\sqrt{97}}{\sqrt{36}}[/tex]

Simplify. So, our distance is:

[tex]d=\frac{\sqrt{97}}{6}\approx1.6415[/tex]

$.48 per bottle

Step-by-step explanation:

The unit price is the total price divided by the number of items

$.48 per bottle

Answer:

Step-by-step explanation:

If the scale showed 2 ounces for a sample of matter and 56.7grams for the same sample, then;

2 ounces = 56.7grams

If She has a rock that weighs 708.75 grams but needs to know the weight in

ounces, we can say;

x ounces = 708.75grams

Combining both equality postulates

2 ounces = 56.7grams

x ounces = 708.75grams

Cross multiply

56.7 × x = 2 × 708.75

x = (2 × 708.75)/56.7

The proportion is (2 × 708.75)/56.7

Calculate x:

x = 1417.5/56.7

x = 25

Hence the weight of the 708.75g rock in ounces is 25ounces
