Mary covered her kitchen floor with 10 tiles. The floor measures 6 feet long by 5 feet wide. The tiles are each 3 feet long and
Talja [164]

Answer:

1 feet wide

Step-by-step explanation:

We first need to find the area of the floor.

6*5=30

Then we divide the area by the number of kitchen tiles to get the area of each tile.

30/10=3

After this, we set up a L x W = A equation to solve for w.

3*w=3

3w=3

w=1

A marketing research company is estimating the average total compensation of party clowns. Data were randomly collected from 48
ExtremeBDS [4]

Answer:

"90% confidence" means there is a probabilty of 90% that the population mean (average compensation for the population of party clowns) lies within the confidence interval.

Step-by-step explanation:

The confidence interval is a range of values in which, according to the level of confidence that is calculated, is likely to include a parameter of the population. In this case, this parameter is the population mean compensation of party clowns.

The level of confidence is 90%, so there is 90% of confidence (or probability) that the population mean compensation for party clowns lie within $9394 and $9926.

None of the options below is correct.

Drag a statement or reason to each box to complete this proof.
Pepsi [2]

In the given quadrilateral ABCD,

m\angle A=7x^{\circ} , m\angle B=5x^{\circ}, m\angle C=7x^{\circ} , m\angle D=5x^{\circ}  (Given)

m\angle A + m\angle B+ m\angle C+ m\angle D=360^{\circ}

(Sum of interior angles of a quadrilateral is 360 degrees)

7x\dot{^{\circ}} + 5x^{\circ}+ 7x\dot{^{\circ}} + 5x^{\circ}=360^{\circ}(Substitution Property)

24x^{\circ}=360\dot{^{\circ}} (Addition Property of Equality)

x=15^{\circ}

A total of $32,000 is invested in two municipal bonds that pay 4.25% and 6.25% simple interest. The investor wants an annual int
Aleks04 [339]

Answer:

$16000 invested in 4.25%  and 16000 invested in 6.25%

Step-by-step explanation:

Let x be the amount invested in 4.25%  and y be the amount invested in 6.25%

4.25%= 0.0425

6.25%= 0.0625

x+y= 32000

subtract x from both sides

y= 32000-x

total interest earned is 1680

0.0425x+0.0625y=1680

0.0425x+0.0625(32000-x)=1680

Now solve for x  and y

0.0425x+2000-0.0625x=1680

subtract 2000 from both sides

-0.02x=1680-2000

-0.02x=-320

divide by -0.02 from both sides

x=16000

y= 32000-x

y= 32000-16000=16000

Find the number if 1 2/3% of it is 4.75
Alecsey [184]
<h2>Answer:</h2>

The number is:

                      285

<h2>Step-by-step explanation:</h2>

It is given that:

1 2/3% of a number is 4.75.

Let the number be x.

We know that:

1\dfrac{2}{3}=\dfrac{1\times 3+2}{3}=\dfrac{5}{3}

This means that:

\dfrac{5}{3}\%\ of\ x=4.75

i.e.

\dfrac{5}{3\times 100}\times x=4.75\\\\\dfrac{1}{60}\times x=4.75\\\\x=4.75\times 60\\\\x=285

Hence, the number is: 285
