Answer:

[tex]\huge\boxed{\texttt{The number is 27.}}[/tex]

Step-by-step explanation:

In order to find the number we need to set up an equation where we represent the unknown number as a variable. I'll call it [tex]n[/tex].

5 times a number can be represented as [tex]5n[/tex].

18 more than that can be represented as [tex]5n+18[/tex].

We know it equals 153, so [tex]5n+18=153[/tex].

We can solve for n by reversing the equation until we have n isolated on one side.

Subtract 18 from both sides:

[tex]5n=135[/tex]

Divide both sides by 5:

[tex]n = 27[/tex]

So our unknown number is 27.

Hope this helped!

Step-by-step explanation:

Answer:

So the width should be 21 cm, to have a length of 99 cm and a perimeter of 240 cm.

Step-by-step explanation:

240 = 2(99) + 2x

240 = 198 + 2x

42 = 2x

21 = x

Answer:

Ahh. I see your troubles with this.

Step-by-step explanation:

So what the paper wants you to do is utilize the Pythagorean Theorem, to find the answer to each question, and whatever answer that turns out to be, you'll color the square with that color.

I'll walk you through the first one! I hope you can do the rest on your own.

Okay, the hypotenuse is 10, and one of the legs is 6. Time to input that!

([tex]a^2=b^2+c^2[/tex] <- Pythagorean Theorem, where a is the hypotenuse, b and c are the legs.)

[tex]100=36+x^2\\x^2=64\\x=8[/tex]

There you go, there's your first answer!

This means that you have to color the square Orange!

Happy Pythagoring!

Answer:

[tex] Area = 101.4 cm^2 [/tex] (3 S.F)

Step-by-step explanation:

Diameter of circle (D) = one side of the equilateral ∆

Circumference of the circle = πD = 48 cm

Thus:

πD = 48

Divide both sides by π

D = [tex] \frac{48}{\pi} [/tex] = 15.3 cm (approximated to nearest tenth)

Since all sides an equilateral ∆ are equal, therefore, and the diameter, D, of the circle given is the same as the length of one side of the ∆, therefore, all sides of the equilateral triangle would be 15.3 cm.

Recall that the area of a triangle can be found if we know lengths of the two sides of the ∆ and the measure of the included angle between both sides.

Since an equilateral ∆ has equal angles, each measuring 60°, then we already have all the information needed to calculate the area of the ∆.

Thus:

Length of the two sides = 15.3 cm and

15.3 cm

Included angle = 60°

Use the following formula:

[tex] Area = \frac{1}{2}ab \times Sin(C) [/tex]

Where,

a = 15.3 cm

b = 15.3 cm

C = 60°

Plug the values into the formula to find the area.

[tex] Area = \frac{1}{2} \times 15.3 \times 15.3 \times Sin(60) [/tex]

[tex] Area = \frac{1 \times 15.3 \times 15.3 \times Sin(60)}{2} [/tex]

[tex] Area = 101.4 cm^2 [/tex] (3 S.F)

Answer:

Angle E is 53 degrees.

Step-by-step explanation:

Let's start with the ABC triangle first.

Since AC=BC, angle A and angle B are equal.

We know that the interior angles of a triangle add up to 180.

106 + A + B = 180

A + B = 74

A = B = 37

Moving on to the BDE triangle.

We have angle B = 37 (it's an opposite angle).

We know that angle D is 90, since this is a right triangle.

90 + 37 + E = 180

E = 53

Answer:

m<F = 79 degrees

Step-by-step explanation:

As per the given information;

m<E = 22, the triangle EDF (the one that is given in the picture) is isosceles (meaning that the sides are congruent).

In an isosceles triangle, (a triangle where the sides are congruent) the base angles (the angles opposite to the two congruent sides) are also congruent. One should also know, that in an isosceles triangle, like in any triangle, the sum of the measures of the angles equals 180 degrees.

Using this we can say that

m<D = m<F

To keep it simple while solving the problem, let's say that they have a value of x degrees.

So,

m<E + m<D + m<F =180

Subsitute

22 + x + x = 180

Simplify and inverse operations

22 + x + x = 180

-22              -22

2x = 158

/2     /2

x = 79

So the measure of <D and <F is 79 degrees.

Answer:

79

Step-by-step explanation:

An acute triangle adds up to 180

subtract 22 from 180

180-22 = 158

divide by 2

158/2 = 79

Answer:

102 degrees

Step-by-step explanation:

m< CDA & m<CBA are both 78 degrees because they are both acute angles.

m<DAB & m<DCB are both 102 degrees because they are both obtuse angles.

Whenever you add 78 + 78 + 102 + 102 you get 360 degrees which is how much a four-sided figure should be.

Hope this helps!

Answer:

∠ DAB = 102°

Step-by-step explanation:

The consecutive angles of a parallelogram are supplementary.

∠ CDA and ∠ DAB are consecutive angles, then

∠ DAB = 180° - 78° = 102°
