Can someone please help explain how to do multi- digit number multiplication? Please help ASAP!

Answers

Answer 1

Answer:

To multiply large numbers, stack the first number on top of the second. Then multiply each digit of the bottom number, from right to left, by the top number. In other words, first multiply the top number by the ones digit of the bottom number.

Step-by-step explanation:24

* 1 5

Answer 2

Answer:

Answer:

Example: 456 times 7

400 times 7 is 2800

50 times 7 is 350

6 times 7 is 42

2800+350+42=3192

the figure below shows segments ac and ef which intersect at point b. segment af is parallel to segment ec: which of these facts is used to prove that triangle abf is similar to triangle cbe? angle fab is equal to angle ceb because corresponding angles are congruent. angle abf is congruent to angle ceb because vertically opposite angles are congruent. angle afb is congruent to angle ceb because alternate interior angles are congruent. angle afb is congruent to angle ceb because supplementary angles are congruent. i chose b, but i'm not positive it is the answer. can anyone give some clarification?

Answers

Answer: Angle AFB is congruent to angle CEB because alternate interior angles are congruent.

Step-by-step explanation:

Given: $fa\parallel ec$ ,

And, ac and ef are intersecting each other at point b.

Prove: Triangle abf is similar to triangle cbe

Since, $\angle abf \cong \angle cbe$ (Reflexive)

$fa\parallel ec$ ,

⇒ ef is the common transversal of parallel lines fa and ec.

$\angle afb \cong \angle ceb$ (Because Alternative interior angles are congruent)

Thus, By AA similarity postulate,

$\triangle abf\sim \triangle cbe$

angle A = angle Cangle F = angle Ebecause of some line through parallel lines postulate

Step-by-step explanation:

A karat equals 1/24 part of gold in an alloy [ eg 9 karat gold is 9/24 gold]. How many grams of 9 karat gold must be mixed with18 karat gold to make 200 grams of 14 karat gold alloy?

Answers

This is a mixture problem.

mass1 * karat1 + mass2*karat = total mass * total carat

Total mass = 200g.
Total karat = 14.

Let the 9 karat gold to be mixed be x. The 18 karat would weight (200 - x). Since the total = 200g.

9*x + 18*(200 -x) = 14*200

9x + 18*200 - 18*x = 14*200

18*200 + 9x - 18x = 14*200

3600 - 9x = 2800

3600 - 2800 = 9x

800 = 9x

9x = 800

x = 800/9

x ≈ 88.89

Therefore 88.89 grams of 9 karat gold must be mixed.

Solve 4^2x=7 by graphing

Answers

Answer:

0.702 is the solution of this function.

Step-by-step explanation:

We have

$4^(2x)=7\n\n4^(2x)-7=0$

Let us plot $y=4^(2x)-7$ when y value of this function is zero then that is the solution of $4^(2x)=7$

Refer the figure given, we have at x = 0.702 y value is zero that is 0.702 is the solution of this function.

I can't solve that by graphing but I'll try logarithms:
log(7)4 = 2x
log(7)/log(4) = 2x
1.403 = 2x
x = 0.702

What is the value of x to the nearest tenth?
A) 9.2
B) 7.2
C) 4.8
D) 12.0

Answers

Answer:

B. 7.2

Step-by-step explanation:

radius=24÷2= 12

other line =19.2÷2=9.6 because line from centre bisects chord and is perpendicular to it

Therefore: X²=√ 12²-9.6² ( theorem of Pythagoras)

X=7.2

Isabel pays $24.07 for 5.8 gallons of gas. What is the unit price in dollars per gallon?

Answers

To find the unit price of gas in dollars per gallon, you can divide the total cost by the number of gallons:

Unit price (dollars per gallon) = Total cost / Number of gallons

Unit price = $24.07 / 5.8 gallons ≈ $4.15 per gallon

So, the unit price of gas is approximately $4.15 per gallon.

Answer:

4.15

Step-by-step explanation:

24.07 divided by 5.8 = 4.15
