How do you write 3.74 x 10-4 in standard form?

Mathematics
1 answer:

Answer:

#3.77xx10^3=37700#

Explanation:

In scientific notation, we write a number so that it has single digit to the left of decimal sign and is multiplied by an integer power of #10#.

In other words, in scientific notation, a number is written as #axx10^n#, where #1<=a<10# and #n# is an integer and #1<=a<10#.

To write the number in normal or standard notation one just needs to multiply by the power #10^n# (or divide if #n# is negative). This means moving decimal #n# digits to right if multiplying by #10^n# and moving decimal #n# digits to left if dividing by #10^n# (i.e. multiplying by #10^(-n)#).

In the given case, as we have the number as #3.77xx10^4#, we need to move decimal digit to the right by four points. For this, let us write #3.77# as #3.770000# and moving decimal point four points to right means #37700.00#

Hence in standard notation #3.77xx10^3=37700#

A student randomly selected crayons from a large bag of crayons. The table below shows the number of each color crayon in a bag.
Assoli18 [71]
<h3>- - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - </h3>

➷ Since 5 out of those 30 crayons are blue, the probability would be:

\frac{5}{30}

This can be simplified to:

\frac{1}{6}

➶ Good Luck (:

➶ Have A Great Day ^-^

Given: JP = KP; PX = PY Prove: ΔPYJ ≅ ΔPXK Triangles P Y J and P X K overlap and intersect at point Z. Point X of triangle P X K
FrozenT [24]

Answer:

Prove: ΔPYJ ≅ ΔPXK

Step-by-step explanation:

Overlapping triangles are said to be triangles that share at least part of a side or an angle.

To prove ΔPYJ is congruent to ΔPXK

First we would draw the diagram obtained from the given information.

Find attached the diagram.

Given:

JP = KP

PX = PY

From the diagram, ΔPYJ and ΔPXK share the line KJ (part of the side of each of the triangle)

KJ ≅ KJ (A reflexive property - the segment is congruent to itself)

In ∆PYJ

JP = KP + KJ

In ∆PXK

KP = JP + KJ

Since JP = KP

KP + KJ = JP + KJ

PJ ≅ PK

The overlapping section makes a smaller triangle KXJ

∠K = ∠J (opposite angles of congruent sides are equal)

In ∆PYJ: PY + YJ + PJ (sum of angles in a triangle)

In ∆PXK: PX + XK + PK (sum of angles in a triangle)

If ΔPYJ ≅ ΔPXK

PY + YJ + PJ = PX + XK + PK

XK ≅ YJ

Therefore, ΔPYJ ≅ ΔPXK

A store sells 2 1/2 pounds of shrimp for $18. What is the unit price of the shrimp? Explain Plz
krok68 [10]
2 1/2 pounds = $18
for 1 pound = How many dollars

1 pound = $18 ÷ 2 1 /2
= 18 ÷ 2.5
= $ 7.2

1 pound = 453.6 grams
so 453.6 grams = $7.2

price of 1 gram = 7.2 / 453.6 = $ 0.0158

Sheila is moving to a new house. She rents a truck with a storage body as shown below.
patriot [66]

Answer:

volume of the storage body is 576. multiply by 9. she can fit 64 boxes

Step-by-step explanation:

so draw a line at the short end of the body so it would be 6ft x 4 ft x 2ft = 48 ft. then the rest of the body becomes 11 ft (15 ft minus 4 ft) x 8ft x 6ft =528. so 48 + 528 = 576 then you divide 576 by 9 and get 64.

I need simple working out thank you for anyone helping me​
Paul [167]

Answer:

Step-by-step explanation:

we know that the triangle to the center is an isosceles,  so the two angle on the circle of that triangle are the same.   both 41,  so 41*2 =82  

all the way around that isosceles triangle is 180  so

180-82 = 98

the angle at O is 98°

the arc BC spans 98°

angle 'a'  is 1/2(98°)

a = 49°
