Split £180 into a 7 : 5 ratio

Answers

7 + 5 = 12
180 / 12 = 15
7 x 15 = 105
5 x 15 = 75
£105 : £75

The splitted bill of  £180 into a 7 : 5 ratios are  £105 and  £75 respectively.

What are ratio and proportion?

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, A bill has to be split £180 in the ratio of 7 : 5.

One part is (7/7 + 5)×180.

= (7/12)×180.

= 105.

Another part is (5/7 + 5)×180.

= (5/12)×180.

= 75.

Answer:

71.1 degrees

Step-by-step explanation:

The side opposite angle A is 35 and that adjacent to angle A is 12.  The trig function that connects A and these two sides is

tan A = (opp) / (adj)

which here is

tan A = 35/12.  Find A using a calculator's arctan function:

arctan 35/12 = 1.25 radian or 71.1 degrees.

Eight cards are picked three, four, five, six, seven, eight, nine, and 10 such that each card has exactly one of these numbers a card is picked without looking find each probability write each answer is a fraction and decimal and a percent P(9)

Answers

Answer:

Probability (Fraction, Decimal, Percentage)  = 1/8 , 0.125 , 12.5%

Step-by-step explanation:

Total cards = 8 ; numbered 'three, four, five, six, seven, eight, nine, ten'

Prob (Card with number three) = card with no. three / total cards = 1/8

Prob (Card with number four) = card with no. four / total cards = 1/8

Similarly , Prob (A Card with any other number) = 1/8

Fraction Probability = 1/8 ; Decimal Probability = 0.125

Percentage probability = 1/8 x 100 = 12.5%

What is one value of x that makes the equation-16x^2+121=0 true

Answers

Answer:

x = ±11/4

Step-by-step explanation:

Rewrite -16x^2+121=0 as 16x^2 - 121=0 and then as 16x^2 = 121.

Take the square root of both sides.  This returns 4x = ±11, and so:

x = ±11/4

265.6 is what percent of 256 rounded to the nearest tenth

Answers

Answer:

103.75 %

Step-by-step explanation:

[tex] \frac{265.6}{256} \times 100[/tex]

Take 265.6 and divide it by your original number of 256. Now multiply this resultant by 100 to see your final answer rounded to the nearest 10th.

Answer:

256:265*100 =

(256*100):265 =

25600:265 = 96.6

Step-by-step explanation:

Percentage solution with steps:

Step 1: We make the assumption that 265 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$x.

Step 3: From step 1, it follows that $100\%=265$100%=265.

Step 4: In the same vein, $x\%=256$x%=256.

Step 5: This gives us a pair of simple equations:

100%=256(1)

x%=256(2)

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%);

100%/x% = 256/256

Step 7: Taking the inverse (or reciprocal) of both sides yields

x%/100%=256/256

-->x=96.6%

Therefore, 256 is 96.6% of 265

A rectangle’s width is one-fourth of its length. Its area is 9 square units. The equation l(l) = 9 can be used to find l, the length of the rectangle.

What is the length of the rectangle?

0.75 units
1.5 units
3 units
6 units

Answers

Answer:

6 units

Step-by-step explanation:

The formula for the area of a rectangle = Length × Width

A rectangle’s width is one-fourth of its length.

W = 1/4 × L

W = L/4

Cross Multiply

L = 4W

A = 9 square units

Hence

9 = L × W

We substitute 4W for L

9 = 4W × W

9 = 4W²

We square root both side

√9 = √4W²

3 = 2W

W = 3/2

W = 1 1/2 unit or 1.5 units

Solving for L = Length

9 = L × W

9 = L × 1.5

L = 9/1.5

L = 6 units

Therefore, the Length of the rectangle = 6 units

Which pair of triangles can be proven congruent by SAS?

Answers

The third set of triangle can be proven by SAS as both triangles have a congruent angle in between two congruent sides.

Third pair of triangles is congruent by SAS.

What is congruency?

In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

If any two sides and angle included between the sides of one triangle are equivalent to the corresponding two sides and the angle between the sides of the second triangle, then the two triangles are said to be congruent by SAS rule.

In the third pair, this rule is visible. Two pair of sides are equal to each other and the angles formed at the common vertex of the two sides are equal. Hence, the two triangles are congruent by SAS.
