Answer:

48in sq

Step-by-step explanation:

8*12/2=8*6=48

Answer:

48in

Step-by-step explanation:

A triangle like this is like half of a rectangle. The rest fits in the upper left and right. So to find the area of the triangle, we're going to start be pretending it's a recrangle.

Our rectangle is 12 by 8.

12 x 8 = 96

If this were a rectangle, the area would be 96in.

Since it's a triangle and that's only half of a rectangle, the area is half of that.

96 / 2 = 48

The area of this triangle is 48in.

Answer:

The family will travel at least 4 days.

Step-by-step explanation:

The inequality would look like this:

350d ≤ 1400

it's ≤ because the problem said that they had to travel AT LEAST a distance of 1400.

To solve the inequality, use inverse operations.

350d ÷ 350 ≤ 1400 ÷ 350

d ≤ 4

the family will travel at least 4 days.

Answer:

(a) Denise received $640.

(b) The total amount the bank charged Denise was £11

Step-by-step explanation:

Proportions and Percentages

The exchange rate between the American Dollar ($) and the British Pound(£) is $1.60= £1.

(a) Denise changed £400 into dollars. Applying the exchange rate:

£400 = 1.60*400 = $640

Denise received $640.

(b) To change the money, we need to add both fees the bank charged Denise:

A fixed amount of £3

2% of £400 = £8

The total amount the bank charged Denise was £11

Answer:

a=54

Step-by-step explanation:

EASY

look triangles are 180 degrees

means all 3 sides add to 180

look at 2a and the missing angle they add up to 180

180-(a+10)-44

missing angle is

−a+126

exteriro plus interior angles add up to 180

-a+126+2a=180

solve and simplify

a=54

x> -5/13

Step-by-step explanation

Given :

To find :

Solution :

As it is given that the length of rectangle is 6 m more than the breadth.

Thus, let us consider the Breadth as ''x''.

Then the Length will be ''x+6''.

We know that,

Perimeter of rectangle = 2(l + b)

According to Question,

➠Perimeter of rectangle = 2(x+6+x)

➠60 = 2(x+6+x)

➠60 = 2(x+x+6)

➠60 = 2(2x + 6)

➠60 = 4x + 12

➠60 - 12 = 4x

➠48 = 4x

➠48/4 = x

➠12 = x

______________________

∴ We got the Value of Breadth as 12 m, because we have let the breadth as x.

And the Length of the rectangle will be,

↠x + 6

↠12 + 6

↠18 m

Hence,

Step-by-step explanation:

Answer:

74 , 76 , 78

Step-by-step explanation:

Let the first of your number be x, As you are only looking at even integers, the next consecutive even integer would be x+2 and the consecutive even integer after that would be x+4. The sum of these three even integers results in 228 so we can say that:

[tex]First\ even\ number\ + Second\ even\ number\ + Third\ even\ number\ =228 \\\\x+(x+2)+(x+4)=228[/tex]

[tex]x+x+2+x+4=228\\3x+6=228\\3x=228-6\\3x=222\\x=222/3\\x=74\\[/tex]

so the first even number is 74 then the second consecutive even number is 76 then the third consecutive even number is 78

Answer:

A, C, E

Step-by-step explanation:

I don't really know how to explain it but you can kinda substitute 9 for the variable to confirm if you want.

Using proportions, it is found that it takes 525,960 minutes for the earth to travel one full rotation around the sun.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

One day has 24 hours of 60 minutes, hence the number of minutes in a single day is given by:

Md = 24 x 60 = 1440 minutes.

Hence, the number of minutes in 365.25 days is given by:

My = 1440 x 365.25 = 525,960 minutes

Answer:

68 or 62 degrees

Step-by-step explanation:

If the 56 degree angle is one of the base angles of the triangle, you can multiply it by two (because base angles of an isosceles triangle

are congruent), and then subtract 180 (because you must subtract the sum of two angles from 180 to get the measure of the third angle).

If the 56 degree is not a base angle, then you can use this equation to get the measurement of each base angle:

(180-56)÷2=measure of each base angle

180=sum of angle measures in a triangle

56=measure of third angle

With 180-56, you get the sum of the base angles, so you must divide by two. (Base angles of an isosceles triangle are congruent)

The other angles that could be in that  isosceles triangle should be considered as the 56°, 68°, or 62°.

Since One angle of an isosceles triangle measures 56°.

So in the case when  56° angle is one of the two congruent angles, so the remaining angles are 56° and 180-2(56) = 68°

Now

In the case when the is 56° Is not congruent to either of the other angles, so each of the remaining two angles should be [tex](180-56)/2[/tex]= 62°.

hence, The other angles can be 56°, 68°, or 62°.

Answer:

$25 a lamp

Step-by-step explanation:

First divide $10,000  by 500 lamps to find how much one of them cost

That is $20 a lamp so then multiply .25 *20 or 1/4 *20

you get 5 than add 20 +5=25

The unit price in cents per ounce will be 17 cents / ounce.

The cost of the 6 ounce frozen orange juice is given as:

Cost = $ 1.02

We know that:

$ 1 = 100 cents.

So, by using multiplication, we get that:

$ 1.02 = 1.02 × 100 cents

$ 1.02 = 102 cents.

Now, Number of ounces = 6 ounces

Unit price in cents per ounce = 102 cents / 6 ounce

Unit price in cents per ounce = 51 cents / 3 ounce

Unit price in cents per ounce = 17 cents / ounce

Therefore, the unit price in cents per ounce will be 17 cents / ounce.

Answer:

[tex]350 * D \geq 1400[/tex]

[tex]D\ge 4[/tex]

This means that the family must travel for at least 4 days.

Step-by-step explanation:

Given

[tex]Rate = 350\ miles\ daily[/tex]

[tex]Distance = 1400\ miles\ (atleast)[/tex]

Required

Determine and solve the inequality

The number of days is represented with D

So:

On any D number of days, the family would have covered a distance of 350 * D miles

If the total distance is at least 1400, then the inequality is:

[tex]350 * D \geq 1400[/tex]

[The term "At least" is used to represent greater than or equal to]

[tex]350 * D \geq 1400[/tex]

Divide through by 350

[tex]\frac{350 * D}{350} \ge \frac{1400}{350}[/tex]

[tex]D \ge \frac{1400}{350}[/tex]

[tex]D\ge 4[/tex]

This means that the family must travel for at least 4 days.
