The width of a rectangle measures (8.4x + 2.2) centimeters, and its length

lorasvet [3.4K]

The algebraic expression that will represent the perimeter in centimeters of the given rectangle is: $(25.8x +11.2) $ cm$

Recall:

Perimeter of a rectangle = 2(L + W)

Given the following dimension of a rectangle:

width (W) = (8.4x + 2.2) cm
length (L) = (4.5x + 3.4) cm

To find the expression that represents the perimeter, plug in the given values into the formula for perimeter.

Thus:

Perimeter = $2((4.5x + 3.4) + (8.4x + 2.2))$

Open the bracket

Perimeter = $2(4.5x + 3.4 + 8.4x + 2.2)$

Add like terms together

Perimeter = $2(12.9x + 5.6)$

Multiply

Perimeter = $25.8x +11.2$

Therefore, the algebraic expression that will represent the perimeter in centimeters of the given rectangle is: $(25.8x +11.2) $ cm$

Find the measure of the arc TDB in the circle P shown below:

andrey2020 [161]

$\huge{ \mathfrak{ \underline{ Answer \: \: ✓ }}}$

The Angle formed by an arc on the centre of the circle is double the angle made by the same arc on the circumference of the circle.

So,

$\boxed{ \mathrm{ \angle TDB = \dfrac{1}{2} \angle TPB }}$

$\mathrm{\angle TDB = \dfrac{1}{2} \times 90 \degree}$

$\mathrm{\angle TDB =45 \degree }$

Asif makes a cuboid of plasticine of sides 75cm, 35cm and 21cm. How many such cuboids will he need to form a cube?

algol [13]

Answer:

The number of cuboids that will be needed to form a cube is 2625 cuboids

Step-by-step explanation:

To form a cube, we have;

The length = The height = The depth

The dimensions of the given cuboid = Length = 75 cm, the width = 35 cm, the depth = 21 cm.

Therefore;

The lowest common multiple of 75, 35, and 21, for the cuboid is given as follows;

75 = 5 × 5 × 3

35 = 5 × 7

21 = 3 × 7

Therefore, multiplying 75 by 7, we get;

75 × 7 = 525

Since 7, 5 and 3 are factors of 525, 35 and 21, can also be factors as we check;

525/35 = 15

525/21 = 25

Therefore, the cube will be;

The length of the cube will consist of 7 pieces of the cuboid, arranged with the side 75 cm facing the front

The depth of the cuboid will be 15 cuboids with the side 35 cm facing the sides

The height of the cuboid will be 25 cuboids with the side 21 cm high

The total number of cuboids is therefore;

7 × 15 × 25 = 2625 cuboids

The number of cuboids that will be needed to form a cube = 2625 cuboids.

Jewel is 7 years old and John is 16 years younger than Dave. One year ago, Dvae's age was twice the sum of Jewel's and John's ag

ivanzaharov [21]

Answer:

Jewel is 7 years old

John is 1 year old

Dave is 17 years old

Step-by-step explanation:

From the question we are told that:

Jewel age is $J=7 years$

John age $J'=(D-16)years$

Dave's age a Year ago

$D-1=2(J-1+J'-1)$

So that Dave.s age this Year could be

$D=2((J-1)+(J'-1))+1$

Simplifying Equation for Dave's age we have

$D=2((7)-1+(D-16)-1)+1$

$D=2(6+D-15)+1$

$D=2(D-9)+1$

$D=2D-18+1$

$D=17 Years$

Dave is 17 years old

Therefore

Johns age is

$J'=(D-16)$

$J'=17-16$

$J'=1year old$

John is 1 year old
