Answer 1

Answer:

a = 2 √13 cm

Step-by-step explanation:

Here, we want to find the length of BC

To do this, we can use the cosine rule

Thus;

a^2 = b^2 + c^2 - 2BC cos A

= 8^2 + 6^2 - 2(8)(6) cos 60

Mathematically cos 60 = 1/2

= 64 + 36 - 48 = 52

a^2 = √52

a = 2 √13 cm

While a gram is a unit of weight equal to 1/1000th of a kilogram. A gram is the approximate weight of a cubic centimeter of water.

Sekhar gives a quarter of his sweets to Renu and then gives 5 sweets to Raji. He has
7 sweets left. How many did he have to start with?​

Answers

Answer:

16 sweets

Step-by-step explanation:

Number of sweet that Sekhar had = x

Sweets given to Renu = (1/4) of x = [tex]\frac{1}{4}x[/tex]

Sweets given to Raji = 5

Remaining sweets = 7

[tex]x = \frac{1}{4}x +5 + 7\\\\x -\frac{1}{4}x = 12\\\\\frac{4*x}{1*4}x-\frac{1}{4}x = 12\\\\\frac{4x}{4}-\frac{1}{4}x= 12\\\\\frac{3x}{4}=12\\\\x = 12*\frac{4}{3}\\\\x=4*4\\\\x=16[/tex]

Find the missing side

Answers

Answer:

20

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2, where a and b are the sides and c is the hypotenuse

15^2 + b^2 = 25^2

225 + b^2 = 625

b^2 = 625 -225

b^2 =400

Take the square root of each side

sqrt(b^2) = sqrt(400)

b = 20

If a car travels 825 miles in 15 hours and the car travels at an constant rate how many miles does the car travel in 1 hour?

Answers

Answer:

55 miles

Step-by-step explanation:

Given data

DIstance =  825 miles

Time = 15 hours

Speed= distance/time

Speed= 825/15

Speed= 55  miles per hour

Given that we want to find the distance traveled in 1 hour, we have

Distance= Speed*time

Distance= 55*1

Distance= 55 miles

Hence the car will travel 55 miles in 1 hour

Heather has divided $5600 between two investments, one paying 9% the other paying 5%. If the return investment is $396, how much does she have in each investment?

Answers

Answer:

x = 2700 y=2900

Step-by-step explanation:

x+y = 5600

5/100 x + 9/100 y = 396

x+y=5600

5x+9y=39600

5x+5y = 28000

5x+9y=39600

-4y = -11600

y= 2900

x = 5600-2900 = 2700

0.9x. +0.6(5600-x)=396
9x + 6 (5600-x) =39600
9x + 33,600 - 6 = 39600
3x = 6000
X = $2000




So 2000 invested at 9% and 3000 invested at 5%

38 is 90 percent of what

Answers

Answer:

42.22 (2 repeating)

Step-by-step explanation:

When you are given percentage problems, you deal with the percent (%), base (amount you are starting with), and the amount.

Starting with the most basic equation,

Percent * Base = Amount

In this problem, you are given the amount (38) and the percent (90)

So to find the base, you can do

Base = Amount / Percent

As always, convert the percent to a decimal by dividing by 100.

38/ 0.9 = 42.222 repeating

Using logarithm table evaluate the

Answers

Answer: 3.845312455 just put it in a scientific calculator

By using the logarithm table, the value of the expression is approximately  written as 5.796.

To begin, let's use the properties of radicals and logarithms to rewrite the expression:

[tex]\frac{\sqrt[3]{1.373} }{\sqrt[4]{0.007} } = 1.373^{1/3} \times 0.007^{-1/4}[/tex]

Now, we can utilize logarithm tables to evaluate each term separately. Using logarithms, we can convert the above expression into a more manageable form:

=> 1.373 ¹/₃ = 1.092,

=> 0.007⁻¹/₄ = 5.311

Finally, we can substitute the approximated values back into the original expression:

≈1.092×5.311≈5.796.

b) David will charge 3 pound for leveling of 1m square What will be the total
amount he will charge for leveling the playground.​

Answers

Answer:

A. 180 m²

B. 540 pounds

Step-by-step explanation:

Area of rectangular playground = length × width

Length of a Rectangular playground = 15m

width of the playground =

12m

Area of rectangular playground = length × width

= 15m × 12m

= 180m²

B. 1m square = 3 pounds

What will be the total amount he will charge for leveling the playground.

Total cost of leveling the playground = 180 m² × 3 pounds

A student wants to arrange four points to form a rectangle on a grid. She has already placed points at Syntax error. Where should she place the last point? PLEASE HURRRY

Answers

Question:

A student wants to arrange four points to form a rectangle on a grid. She has already placed points at (-4. 4). (-4, 8). and (4, 8). Where should she place the last point?

Answer:

[tex]D = (4,4)[/tex]

Step-by-step explanation:

Let the rectangle be ABCD

[tex]A = (-4,4)[/tex]

[tex]B= (-4,8)[/tex]

[tex]C = (4,8)[/tex]

Required

Determine the location of the last point

A rectangle has the following coordinates

[tex]A = (x_1,y_1)[/tex]

[tex]B = (x_1,y_2)[/tex]

[tex]C = (x_2,y_2)[/tex]

[tex]D = (x_2,y_1)[/tex]

From the given coordinates:

[tex]x_1 = -4[/tex] --- see x coordinates of A and B

[tex]x_2 = 4[/tex] --- see x coordinates of C

[tex]y_1 =4[/tex] --- see y coordinates of C

[tex]y_2 =8[/tex] --- see y coordinates of B and C

So:

[tex]D = (x_2,y_1)[/tex]

[tex]x_2 = 4[/tex]

[tex]y_1 =4[/tex]

The coordinates of the last point (D) is:

[tex]D = (4,4)[/tex]

What is the y-intercept of function g if g(x) = 2f(x) + 1 ?

A. (0,2)
B. (0,-1)
C. (0,3)
D. (0,1)

Answers

By evaluating the function in x = 0, we will see that the y-intercept is (0, 3), so the correct option is C.

How to find the y-intercept of a function?

The y-intercept of a function g(x) is given by evaluating the function in x = 0.

So the y-intercept of g(x) is:

y = g(0).

In this case, we have:

g(x) = 2f(x) + 1

The y-intercept will be:

g(0) = 2*f(0) + 1

By looking at the graph, we can see that f(0) = 1, replacing that above we get:

g(0) = 2*1 + 1 = 3

Then the y-intercept is the point (0, 3), meaning that the correct option is C.

the angles of a quadrilateral are x°, (x+5)°, (2x-25)° and (x+10)°
find the value of x​

Answers

Given:

The angles of a quadrilateral are x°, (x+5)°, (2x-25)° and (x+10)°.

To find:

The value of x.

Solution:

We know that the sum of all interior angles of a quadrilateral is 360°. So,

[tex]x^\circ+(x+5)^\circ+(2x-25)^\circ+(x+10)^\circ=180^\circ[/tex]

[tex](5x-10)^\circ=180^\circ[/tex]

It can be written as

[tex](5x-10)=180[/tex]

[tex]5x=180+10[/tex]

[tex]5x=190[/tex]

Divide both sides by 5.

[tex]x=\dfrac{190}{5}[/tex]

[tex]x=38[/tex]

Therefore, the value of x is 38.

Answers

D has the same answer. D has the same answer, because a means -14 + 8 which equals -6 which isn’t equal to the answer to the first one (-22). The next one you switch the - to a + and the -8 to 8 so it would equal 22. C equals -6 which also doesn’t equals the first one. So the last one is right because one you add to negative so still end up with a negative.

the slope would be 4/2 because if you do the triangle method you see that the vertical distance of y is 4 and the horizontal distance of x is 2 so that gives you 4/2 the y intercept is where the line starts at 0 which you can see is 3. if the equation is y=mx+b you plug in the slope which is 4/2 or 2 and plug in the y-intercept which is 3 which gives you y=2x+3

Probability of drawing one yellow ball from a box containing 20 blue balls, 15 white balls and 10 yellow

In this case, there are a total of [tex]20+15+10=45[/tex] ways to choose any ball, since there are [tex]45[/tex] balls in the box. However, only [tex]10[/tex] are yellow, so there are [tex]10[/tex] ways to successfully choose a yellow ball.

Options B and C don't work because we don't know the initial values and an initial value would be represented in the equation.
