2 answers:

6 0

This is not a difficult question and I will help you solve it :)

When calculating 1/10 from 40, what we have to do is this:

(1/10) * 40 = 4

This means that we have to multiply 40 by 1 and divide by 10 :)

So the answer in this case is 4.

'of' in mathematics means multiplication

$\frac{1}{10} \times 40 = \frac{40}{10} = \frac{4\times 10}{1\times 10} = \frac{4}{1} = \boxed{4}$

Find two numbers with a sum of 20 and a difference of 14

sergey [27]

Find two numbers with a sum of 20 and a difference of 14

Make two equations

X+Y=20

X-Y=14

Now add x since y cancels out and add 20+14 To end up with

2x=34

Now divide 2 both sides to get x alone

2x/2=34/2

X=17

Now substitute x answer to first equation and solve for y

17+y=20

Subtract 17 both sides

Y= 3

Your two numbers are

3 and 17

1. A wooden box is to be built so that it measures 156 cm by 122 cm by 95 cm.

NeX [460]

The amount of plywood needed to build the garbage bin is the surface area. Therefore, the amount of plywood needed is 90884 cm².

<h3>How to find the surface area of a rectangular prism</h3>

The wooden box is a rectangular prism. The amount of plywood used to construct the wooden box is the surface area of the box.

Therefore,

surface area of rectangular prism = 2(lw + lh + hw)

where

l = length
w = width
h = height

l = 156 cm

w = 122 cm

h = 95 cm

surface area of rectangular prism = 2((156 × 122) + (156 × 95) + (122 × 95))

surface area of rectangular prism = 2(19032 + 14820 + 11590)

surface area of rectangular prism = 2(45442)

surface area of rectangular prism = 90884 cm²

For 30 minutes you do a combination of walking and jogging At the end of your workout your screen displays 2.5 miles you know th

tigry1 [53]

Let the time spent in walking = x minutes

And the time spent in jogging = y minutes

If I walk with the speed = 0.05 miles per minute

Distance covered in walking = Speed × Time

= 0.05x miles

If I jog with the speed = 0.1 miles per minute

Distance covered in jogging = Speed × Time

= 0.1y miles

Since, screen displays the distance covered in walking and jogging = 2.5 miles

Equation for the situation will be,

0.05x + 0.1y = 2.5

5x + 10y = 250

x + 2y = 50 -------(1)

Total time spent in walking and jogging = 30 minutes

Therefore, equation for the situation will be,

x + y = 30 ----- (2)

By subtracting equation (2) from equation (1),

(x + 2y) - (x + y) = 50 - 30

y = 20 minutes

By substituting the value of y in equation (2),

x + 20 = 30

x = 10 minutes

Therefore, time spent in walking is 10 minutes and time spent in jogging is 20 minutes.

PLEASE PLEASE HELP I DON'T UNDERSTAND AND IT'S DUE TMRW

zmey [24]

The answer to the above math expression is . See the computation below.

<h3>What is the calculation justifying the above?</h3>

First we solve for the numerator. The numerator is:

7√2 - 2√16

Where:

7√2 = 9.89949493661; and

2√16 = 8

Hence,

7√2 - 2√16 = 1.89949493661

Next we solve for the denominator. This is given as:

3√8=8.48528137424

Hence,

(7√2 - 2√16)/3√8 = 1.89949493661/8.48528137424

= 0.22385762508

$\approx$ 0.224

melisa1 [442]

Answer:

The test statistic | t | =4.45

Step-by-step explanation:

Given that the first sample size n₁ = 36

Given that the second sample size n₂ = 34

Mean of the first sample x₁⁻ = 68.5

Mean of the second sample x₂⁻ = 70

Test statistic

$t = \frac{x^{-} _{1}-x^{-} _{2} }{\sqrt{S^{2} (\frac{1}{n_{1} }+\frac{1}{n_{2} } } )}$

$t = \frac{68.5-70}{\sqrt{2(\frac{1}{36}+\frac{1}{34} ) } }$

$t = \frac{-1.5}{0.337} = -4.45$

The test statistic | t | = |-4.45| =4.45
